National Institute of Science and Technology –<br />

Antarctic Environmental Research<br />

<strong>Instituto</strong> Nacional <strong>de</strong> Ciência e Tecnologia – Antártico <strong>de</strong> Pesquisas Ambientais (INCT-APA)<br />

The importance of Antarctic Research<br />

Antarctica is the most preserved region of the planet and<br />

one of the most vulnerable to global environmental changes.<br />

Alterations in the Antarctic environment, natural or caused<br />

by human activities, have the potential to provoke biological,<br />

environmental and socio-economic impacts, which can<br />

affect the terrestrial system as a whole. For this reason, the<br />

scientific research in Polar Regions is of great environmental<br />

and economic importance, since it contributes to the<br />

comprehension of climatic and environmental changes<br />

observed in these regions, offering support to policy makers.<br />

The protection of the Antarctic environment is one of<br />

highest priorities of all the nations that operate on the<br />

continent. For this reason the region should continue<br />

to be the most preserved of the planet, harmonizing the<br />

presence of man and the atten<strong>da</strong>nce of mankind’s needs<br />

related to the mitigation of environmental impact of an<br />

ecosystem which is highly fragile. In 1991, the concerns<br />

over the consequences of human activity in the Antarctic<br />

environment became a reality through the Protocol on<br />

Environmental Protection to the Antarctic Treaty. This<br />

protocol established directives and procedures, which<br />

should be adopted in the un<strong>de</strong>rtaking of activities in<br />

Antarctica. The monitoring of the environmental impact of<br />

Brazilian activities in Antarctica is a commitment assumed<br />

by the Brazilian Government through the ratification of the<br />

Madrid Protocol (1994).<br />

The position of Brazil as consultative member of the<br />

Antarctica Treaty <strong>de</strong>mands an active scientific role at<br />

the Brazilian Antarctic Program, which is un<strong>de</strong>rtaken by<br />

means of:<br />

• Consoli<strong>da</strong>tion of Brazilian research groups in Antarctic<br />

science;<br />

• The un<strong>de</strong>rtaking of Applied and Basic research on<br />

Antarctica for un<strong>de</strong>rstanding the structure and the<br />

function of Antarctic ecosystems. Hence, this knowledge<br />

contributes to management and preservation of this<br />

ecosystem;<br />

• Formation of human resources for higher education and<br />

for scientific and technological <strong>de</strong>velopment;<br />

• Incentive for an interdisciplinary approach to scientific<br />

questions involving Antarctic systems, at the most<br />

diverse levels;<br />

• Generation of knowledge through Antarctic ecosystems<br />

and transfer of this knowledge to Society;<br />

• Consoli<strong>da</strong>te the results obtained by the INCT-APA<br />

scientific research and, communicate it to policy<br />

makers to contribute to <strong>de</strong>fine policies gui<strong>de</strong>d towards<br />

conservation and management of Antarctic region.<br />

Some of the Benefits to Society:<br />

• Improvement of the climate analysis and forecasts for the<br />

whole Brazilian Territory (improvement of the national<br />

climatic mo<strong>de</strong>ls and the weather forecasting system);<br />

• Application of knowledge of physical processes in the<br />

upper atmosphere and in the ionosphere, interactions<br />

with solar radiation (prevention of telecommunication<br />

inci<strong>de</strong>nts);<br />

• Investigation concerning radiation variations as a<br />

result of global atmosphere changes and their impacts<br />

(monitoring of the ozone layer, UV-B radiation,<br />

consequences to human population, e.g. cancer and<br />

glaucoma);<br />

• The <strong>de</strong>velopment of investigative studies concerning the<br />

possible impacts of global changes in Antarctica (global<br />

warming, natural disasters, ice-melt, and preventative<br />

and corrective initiatives of impacts of these kinds of<br />

occurrences);<br />

• Production of knowledge and critical mass to support<br />

<strong>de</strong>cisions and policy recommen<strong>da</strong>tions concerning<br />

biological diversity (sustainable use of live resources);<br />

• Integration of geophysical, geological and biological<br />

investigations related to the Austral Ocean (support for<br />

4 | Annual Activity Report 2011


interdisciplinary research and full knowledge of the<br />

Antarctic region);<br />

• Implementation of a social programme for educational<br />

and outreach activities (creation of public awareness on<br />

Antarctic Research and the importance of this continent<br />

for the planet).<br />

What is the INCT – Antarctic<br />

Environmental Research?<br />

The National Institute of Science and Technology - Antarctic<br />

Environmental Research (abbreviated as INCT in Brazilian<br />

Portuguese used in this document as INCT-APA hitherto)<br />

was created by the Brazilian Ministry of Science, Technology<br />

and Innovation (Ministério <strong>de</strong> Ciência, Tecnologia e<br />

Inovação -MCTI) in search of excellence in scientific<br />

activities at an international level in strategic areas <strong>de</strong>fined<br />

by the Action Plan 2007-2010 of the Science Programme,<br />

Technology and Innovation for Antarctica, by means of<br />

programmes and instruments ma<strong>de</strong> operational by CNPq<br />

and by FAPERJ (Research support Foun<strong>da</strong>tions at different<br />

levels). The referred initiative has the view to implement a<br />

network of atmospheric, terrestrial and marine monitoring<br />

in the Antarctic region.<br />

Who are we?<br />

INCT-APA consists of more than 70 researchers who,<br />

in an integrated manner, evaluate the local and global<br />

environmental impacts in the atmospheric, terrestrial<br />

and marine areas of Maritime Antarctica systems and,<br />

in addition, are involved in the related educational and<br />

scientific outreach of their activities. The research <strong>de</strong>veloped<br />

by INCT-APA will contribute to influence initiatives<br />

concerning biological diversity and environmental<br />

protection of Antarctica, principally in the scope of the<br />

Ministry of Science, Technology and Innovation, and<br />

the Ministry of the Environment. Furthermore, it assists<br />

in educational processes with the purpose of divulging<br />

Antarctic research to the public in general.<br />

introduction<br />

Advances In Brazilian Research In Admiralty Bay<br />

Dr. Yocie Yoneshigue Valentin (IB/<strong>UFRJ</strong>) – General Coordinator of the National Institute of<br />

Science and Technology – Antarctic Environmental Research INCT-APA<br />

yocie@biologia.ufrj.br; yocievalentin@gmail.com<br />

The National Institute of Science and Technology –<br />

Antarctic Environmental Research – un<strong>de</strong>rtakes its<br />

research studies having as driving gui<strong>de</strong>line the Antarctic<br />

Environmental Biocomplexity, based on long term studies<br />

of processes in the atmospheric, marine and terrestrial<br />

environments and its relationships with human activities,<br />

especially in Admiralty Bay (King George Island, South<br />

Shetlands Islands, Maritime Antarctica, 62°S) and adjacent<br />

areas. In this context, the research studies un<strong>de</strong>rtaken<br />

by Brazil over the last 30 years, including those activities<br />

<strong>de</strong>veloped by INCT- APA in Brazilian Antarctic Operations<br />

XXVII, XXVIII, XXIX and XXX, showed that significant<br />

environmental changes are being observed in the Antarctic<br />

region and some of them are evi<strong>de</strong>nced in the several studies<br />

shown in the present report.<br />

Climate records of the last 30 years have shown great<br />

climatic variation in the region where Admiralty Bay is<br />

located. Temperature measurements have shown evi<strong>de</strong>nce<br />

of a ten<strong>de</strong>ncy of heating up (average annual increase of<br />

+0.23 °C). However, from 2007 on, the monitoring of the<br />

air temperature showed a <strong>de</strong>cline, marked by very severe<br />

winters. In 2010 the col<strong>de</strong>st summer of the region in the<br />

last <strong>de</strong>ca<strong>de</strong>s was recor<strong>de</strong>d. The measurements of the Ozone<br />

layer also show a big annual variability over the region of<br />

the Keller Peninsula (King George Island, Antarctica) and<br />

the continuous measurements of UV-A and UV-B radiation<br />

in Admiralty Bay have indicated an increase of radiation<br />

during the occurrence of ozone hole phenomenon. Still<br />

related to atmosphere, studies concerning the behaviour<br />

of the ionosphere between 2004 and 2010 confirmed that<br />

the layer is controlled by solar radiation, whose effect is<br />

well <strong>de</strong>fined during the months of the austral summer,<br />

while in the period April and October is strongly affected<br />

by meteorological processes.<br />

In the terrestrial environment, the studies regarding the<br />

diversity of vegetation and birds communities, have shown<br />

that these are directly exposed to the effects of reduction of<br />

the ozone layer and the consequent increase of UV radiation,<br />

as well as a series of processes originating from anthropic<br />

activities which can occur in the Antarctic region. The<br />

mapping out of terrestrial community has shown that these<br />

are good indicators of the environmental geomorphological<br />

and hydrological conditions in the Antarctic Peninsula.<br />

Up to the present time, 60 species of Bryopsi<strong>da</strong> (mosses),<br />

distributed in 15 Families, apart from the latter, 126 species<br />

of lichens were i<strong>de</strong>ntified, and three species of small size of<br />

vascular plants (with seeds): Deschampsia antarctica and<br />

Colobanthus quitensis (both native species), and Poa annua<br />

(exotic inva<strong>de</strong>r).<br />

Regarding the seabird communities, the Brazilian<br />

studies un<strong>de</strong>rtaken in King George Island and on Elephant<br />

Island, had the purpose of un<strong>de</strong>rstanding the relationship<br />

of population variations and the distribution of seabird<br />

species as a result of climatic variations, including the<br />

possible impacts directly related to human presence in the<br />

region. Through the methods of counting and population<br />

mapping of the main breeding species on King George Island<br />

(Admiralty Bay and Turret Point), the responses of these<br />

species in the light of the temperature variations, pressure,<br />

winds, climate change indices (Southern Oscillation and<br />

Antarctic Oscillation) and intensity of fishing were evaluated.<br />

From these studies the reduction of some species of birds<br />

was verified. In Stinker Point, the penguin Pygoscelis papua<br />

had its population reduced by almost 20% between 1987 and<br />

2012, and the population of Pygoscelis antarctica <strong>de</strong>clined<br />

approximately 60% in the last 20 years, both at Stinker Point<br />

as well as in Admiralty Bay. The <strong>de</strong>clines are being attributed<br />

to the reduction of the availability of food, especially Krill<br />

(Euphausia superba), due to the variations of the extent<br />

10 | Annual Activity Report 2011


and thickness of the ice layers in winter, of the intense<br />

fishing that occurs in the region of the South Shetland<br />

Islands, and the recovery of the population of cetaceans<br />

and pinnipe<strong>de</strong>s. Other seabirds, for example, Sterna vittata<br />

(Antarctic tern) and Macronectes giganteus (Giant petrel),<br />

also had their populations reduced in Admiralty Bay, but<br />

possibly they have increased on other islands of the South<br />

Shetlands Islands,like Stinker Point, in Elephant Island and<br />

on Penguin Island.<br />

In the marine environment, several studies are being<br />

<strong>de</strong>veloped by Brazilian researchers in the region of<br />

the Antarctica Peninsula, especially in Admiralty Bay<br />

and adjacent oceanic areas. In these are inclu<strong>de</strong>d the<br />

studies carried out during scientific studies: NETWORK<br />

1 – Global Environmental Changes and NETWORK<br />

2 – Environmental Management in Admiralty Bay, King<br />

George Island, Antarctica (2002-2006); Projects linked<br />

to the International Polar Year (2007-2009); PRO-OASIS,<br />

INCT-APA, INCT – Cryosphere and other 19 projects which<br />

make up the process 23/2009 of the National Council for<br />

Scientific and Technological Development (CNPq).<br />

Regarding Admiralty Bay, these studies verified that<br />

there exists an intense mixture in the water column of the<br />

bay, caused by ti<strong>de</strong>s and by the winds. This reduces the<br />

stability of the water column, inducing large variations of<br />

phytoplankton primary productivity in the coastal zone.<br />

The monitoring of the phytoplanktonic community at preestablished<br />

points of Admiralty Bay, at the beginning and at<br />

the end of summer, has verified that nano and picoplankton<br />

algae predominate the phytoplankton of this bay, originating<br />

from the Bransfield Strait and that together contribute with<br />

approximately 70 % of the total chlorophyll observed.<br />

The benthic marine ecosystem of Admiralty Bay has<br />

been studied by Brazilian researchers for some 30 years,<br />

and this has resulted in research results that recor<strong>de</strong>d 1.300<br />

species of benthic organisms at <strong>de</strong>pths of between 0 and 500<br />

metres, in consoli<strong>da</strong>ted and non-consoli<strong>da</strong>ted substrates.<br />

These studies have shown that Admiralty Bay contains 20%<br />

of the 4.100 species of benthic organisms <strong>de</strong>scribed for<br />

the Antarctic region. This has led the Scientific Committee<br />

Antarctic Research (SCAR), to consi<strong>de</strong>r Admiralty Bay as<br />

one of the locations of greater scientific and ecological<br />

interest in Antarctica.<br />

Other studies of physiological, biochemical and<br />

molecular nature have contributed to the un<strong>de</strong>rstanding<br />

of metabolic and morphofunctional a<strong>da</strong>ptations imposed<br />

by the selective pressure of low temperatures and of food<br />

seasonality factors. In addition to the latter, there are<br />

studies on traces of metals and persistent organic pollutants<br />

(POPs) in marine organisms, in the sediment and in the<br />

water, which corroborate with information concerning<br />

the environmental monitoring of Admiralty Bay. The<br />

studies <strong>de</strong>veloped about the biomarkers with natural and<br />

anthropic impacts have contributed to the diagnostic of<br />

the environmental alterations and to the i<strong>de</strong>ntification of<br />

metabolic and histopathological responses of Antarctic<br />

organisms of the Admiralty Bay ASMA (Antarctic Specially<br />

Managed Area). These are integrated together with the<br />

biotic and abiotic <strong>da</strong>ta generated by several lines of ongoing<br />

research in the area, with the objective of subsidising the<br />

environmental monitoring of this ASMA.<br />

In parallel to the activities of physical, chemical and<br />

biological research, the INCT-APA also has activities in<br />

technological areas. For example, the technological studies<br />

related to the air quality in confined areas, which can be<br />

especially affected by construction materials with some<br />

level of toxicity and by the activity which takes places in its<br />

interior; the performance of building in relation to thermal,<br />

acoustic and luminosity comfort, which directly interferes<br />

in the consumption of local energy.<br />

In or<strong>de</strong>r for the research activities of Antarctic to<br />

effectively occur, energy is necessary for the transport and<br />

settling down of the researchers, for the functioning of the<br />

Brazilian Station research laboratories in general and for<br />

the movement of machinery, vessels, etc. As a consequence,<br />

the transport and storage of fossil fuels in the proximity<br />

of the scientific Stations in Antarctica is necessary. Every<br />

year, hundreds of thousands of litres of fuel, especially<br />

diesel oil, go through these transport and storage and<br />

usage stages when all the stipulated safety measures are<br />

taken to avoid the occurrence of acci<strong>de</strong>nts. However, it is<br />

impossible to eliminate 100% of the risk of leakages and<br />

inci<strong>de</strong>nts are frequent with varying magnitu<strong>de</strong>. On the<br />

ground, especially in the area of proximity to fuel storage<br />

tanks, contamination of the soil by diesel oil occurs. In the<br />

past there was no knowledge or sufficient technology for<br />

immediate intervention and avoi<strong>da</strong>nce of the spreading<br />

of soil contamination. At present, successful techniques of<br />

bioremediation have appeared, and these based on the ability<br />

of microorganisms to use the oil as a source of carbon and<br />

energy, transforming complex and toxic substances into CO 2<br />

and water, in the presence of sufficient concentration. This<br />

is one of research lines presently <strong>de</strong>veloped by INCT-APA,<br />

with the purpose of <strong>de</strong>veloping bioremediation methods<br />

that can be used in the contaminated soils of Brazilian<br />

Antarctic Station – Coman<strong>da</strong>nte Ferraz (EACF, Portuguese<br />

acronym) for the reduction of hydrocarbon concentrations<br />

originating from diesel oil and, more importantly, to<br />

establish a technology that can be available for all the<br />

Antarctica, being applicable immediately following an<br />

inci<strong>de</strong>nt, thus avoiding contamination.<br />

Within the technological activities of INCT-APA,<br />

attention is called to the <strong>de</strong>velopment of the Environmental<br />

Management System (EMS) for the Brazilian Antarctic<br />

Station – Coman<strong>da</strong>nte Ferraz (SGA/EACF, Portuguese<br />

acronym, henceforth EMS). The EMS has the purpose<br />

of strengthening and formalising the compliance of<br />

the principles related to the protection of the Antarctic<br />

environment, established in the Madrid Protocol, in such<br />

a way as to limit the negative impacts of atmospheric,<br />

terrestrial and marine environments. This system functions<br />

by i<strong>de</strong>ntifying the environmental aspects and <strong>de</strong>fining the<br />

significant environmental impacts as a consequence of<br />

these activities, apart from establishing procedures, creating<br />

plans for the compliance of objectives from the <strong>de</strong>finition<br />

Introduction<br />

The monitoring of the Antarctic atmosphere and ocean<br />

and their influence on South America is being built on<br />

a consoli<strong>da</strong>ted basis as continuous studies have been<br />

un<strong>de</strong>rtaken by Brazilian researchers in the Antarctic region<br />

for <strong>de</strong>ca<strong>de</strong>s. The i<strong>de</strong>a is to give continuity to these studies,<br />

which require long-term series, for a better un<strong>de</strong>rstanding<br />

of global changes, and to use the <strong>da</strong>ta in numerical mo<strong>de</strong>ls<br />

of climate and weather forecasting so more trustworthy<br />

forecasts can be done. The mentioned projects, because<br />

they were not being consi<strong>de</strong>red as monitoring activities<br />

over the years, have always been un<strong>de</strong>r the threat of<br />

interruption. More than two <strong>de</strong>ca<strong>de</strong>s of continuous studies<br />

on the ozone hole and on the influence of Antarctic cold<br />

fronts on our climate, besi<strong>de</strong>s other highly relevant studies,<br />

must, therefore, have their continuity guaranteed. It is<br />

essential that such activities are associated with a long term<br />

monitoring program.<br />

Antarctica plays an essential role in the thermal<br />

equilibrium of the planet. In relation to South America<br />

this is especially relevant. The climate of the Southern<br />

hemisphere is essentially controlled by air masses originated<br />

from the frozen continent.<br />

It is well known that the energy, which comes from the<br />

Sun, is not constant and can cause variation on the earth’s<br />

climate, on global meteorology, and on the environment.<br />

Recent studies have shown that solar radiation can alter<br />

the physical-chemical properties of the atmosphere and<br />

can influence the wind regime and the amount of UV<br />

radiation, which reaches the earth’s surface, as well as the<br />

cloud coverage and precipitation.<br />

The un<strong>de</strong>rstanding of the interaction between the<br />

chemistry of the atmosphere and climate change is a new<br />

and instigating research area. The connection between<br />

atmosphere and solar radiation, especially UV, which<br />

triggers the chemical reactions and these, in their turn,<br />

<strong>de</strong>pend on the temperature, atmospheric circulation<br />

and climate, are now been studied in an integrated and<br />

systematic manner.<br />

New questions are arising with the observed changes<br />

on the atmospheric temperature profile, especially with<br />

the increase on the troposphere (near surface, as a result of<br />

green house gases) and the <strong>de</strong>crease of the low stratosphere<br />

(between 15 and 20 Km, because of the <strong>de</strong>struction of<br />

ozone hole) and of the mesosphere (between 90 and 100<br />

km, cause attributed to the increase of green house gases).<br />

The main questions are: What are the chemical changes<br />

that are occurring in the different layers of the atmosphere<br />

with increase of UV radiation and changes in temperature?<br />

What are the consequences for the dynamic, circulation and<br />

equilibrium between the atmospheric layers?<br />

Objectives<br />

Monitor and Evaluate<br />

Changes in chemistry and atmospheric dynamics and its<br />

influence on climate, involving: the interaction Sun – Earth,<br />

the temperature in the mesosphere, planetary waves, the<br />

Hole in the Ozone, trace gas associated with the chemistry<br />

of the ozone layer, greenhouse effect emissions, greenhouse<br />

gases caused by human activity in the area of the Brazilian<br />

Antarctic Station Coman<strong>da</strong>nte Ferraz (EACF, Portuguese<br />

acronym, from now on) and the impacts of UV radiation<br />

in the ecosystem.<br />

One of the most important properties of the atmosphere<br />

is its ability to withstand wave motion. Gravity waves are<br />

well known to play an important role in the atmosphere,<br />

e.g. its influence on the thermal state and the atmospheric<br />

circulation. The observation of gravity waves has been<br />

conducted on a large scale in regions of low and mid<br />

latitu<strong>de</strong>s. However, at high latitu<strong>de</strong>s, such as in Antarctica,<br />

these observations are sparse and little is known of the<br />

characteristics of these waves. Studies are being conducted<br />

on them at EACF (62° S and 58° W), through campaigns<br />

with observations of airglow imagers at different latitu<strong>de</strong>s<br />

(Bageston et al., 2009). The study of planetary waves and<br />

gravity waves allow us to i<strong>de</strong>ntify and better un<strong>de</strong>rstand the<br />

dynamics of the neutral upper atmosphere (mesosphere)<br />

and its interaction with the other layers of the atmosphere.<br />

The observation of this dynamic from Antarctica to Ecuador<br />

will i<strong>de</strong>ntify the various transport processes and dynamic<br />

connection and how this affects the atmosphere.<br />

The variability observed in the ozone layer and in the<br />

ground intensity of the UV-A and UV-B radiation, in the<br />

last years, was accompanied by changes in the ionized<br />

layer of our atmosphere, the ionosphere. A <strong>de</strong>tailed study<br />

of ionosphere behavior has been un<strong>de</strong>rtaken at EACF in<br />

the last <strong>de</strong>ca<strong>de</strong>. The long term ionosphere behavior shows<br />

clearly it is controlled by the solar radiation, presenting a<br />

slow variation in close association with the intensity of the<br />

solar radiation associated with the <strong>de</strong>creasing activity of<br />

the 23 rd solar cycle and the increasing of the 24 th (Correia,<br />

2011; Correia et al., 2011). Furthermore, during the local<br />

wintertime (April to October in the southern hemisphere<br />

and October to March in the northern hemisphere), the<br />

ionosphere behavior was strongly affected by meteorological<br />

processes from below in all years. The dynamic processes of<br />

the lower-laying atmospheric levels are associated with the<br />

generation of waves, particularly the gravity waves (period<br />

of minutes/hours) and planetary waves (period of <strong>da</strong>ys),<br />

among others. This study showed that during the wintertime<br />

the planetary waves can strongly affect the lower ionosphere<br />

(Correia, 2011; Correia et al., 2011), evi<strong>de</strong>ncing the coupling<br />

between the different atmospheric layers. In addition to the<br />

effect of the planetary waves in the lower ionosphere, these<br />

studies also suggested an interannual variation, which also<br />

has been observed in physical atmospheric parameters, and<br />

it is attributed to the interaction between the atmospheric<br />

waves and winds, as well as to the inter-hemispheric<br />

coupling.<br />

Measurements of ozone concentration obtained by<br />

Brazilian researchers since 1990 to <strong>da</strong>te have shown a<br />

large annual variability over the region of Keller Peninsula<br />

(King George Island, Antarctica), ranging from 70% in<br />

2006 to 55% in 2010. The latter is compared with the<br />

normal concentration, before 1980, when for the first time<br />

it was observed that this layer was <strong>de</strong>creasing over the<br />

South Pole Recovery time. The changed the layer was still<br />

showing reductions in December due to high temperatures,<br />

although the atmosphere was already presenting a scenario<br />

to normalize the <strong>de</strong>struction. The ozone hole occurs only<br />

in very cold atmosphere (characteristic of the South Pole)<br />

and every year when summer arrives in Antarctica the hole<br />

recovers in December, but not to the same level of 1980 that<br />

is the benchmark of what we consi<strong>de</strong>r Normal.<br />

One consequence of this <strong>de</strong>creased concentration of<br />

ozone layer is increased UV radiation. This increase in<br />

radiation is confirmed by extreme events over Antarctica<br />

and South America, including southern Brazil where in<br />

2010 it was possible to observe a 25% reduction in the<br />

concentration of ozone. The southern region of Brazil<br />

is subject to reductions of ozone during the months of<br />

October and November, which may be called si<strong>de</strong> effects<br />

of the Antarctic ozone hole. This shows that there is still a<br />

large amount of chlorofluorocarbon (CFC) in the Antarctic<br />

atmosphere, and its annual variability is a consequence of<br />

temperature in the stratosphere (the region between 15-50<br />

km altitu<strong>de</strong>s) in the Antarctic winter. The monitoring of<br />

the ozone layer has also indicated that the <strong>de</strong>crease of the<br />

same causes change in temperature of the stratosphere and<br />

affects the chemical makeup of some greenhouse gases such<br />

as CO2 and ozone surface forming a line to Rio Gran<strong>de</strong> do<br />

Sul Southern Brazil excessively increasing the inci<strong>de</strong>nce of<br />

UV-B radiation and contributes to the increased number<br />

of cases of glaucoma, skin cancer and <strong>de</strong>terioration of<br />

the DNA in this region of the country as well as <strong>da</strong>mage<br />

to chlorophyll molecules of algae and plants. In large<br />

urban areas the increase of the UV radiation changes the<br />

atmospheric photochemical composition, potentiating the<br />

effect of pollutant gases at ground level.<br />

The monitoring of ultraviolet radiation and ozone in the<br />

Antarctic Peninsula, Punta Arenas (Chile), Rio Gallegos,<br />

Argentina and in southern Brazil has the purpose of<br />

<strong>de</strong>monstrating the influence of the ozone hole in South<br />

America. Continuous measurements of UV-A and UV-B<br />

recor<strong>de</strong>d in these regions have shown increased radiation<br />

18 | Annual Activity Report 2011


during the occurrence of the ozone hole. In 2009 the land<br />

area around EACF registered an increase in UV radiation of<br />

over 150% compared to the normal concentration, without<br />

the presence of the ozone hole (Paes Leme et al., 2010).<br />

An extremely persistent ozone hole overpass was<br />

observed from ground-based instruments at Rio Gallegos,<br />

Argentina, in November 2009. This was the first time that<br />

an extreme event of this duration was observed from the<br />

ground at a subpolar station with a LIDAR instrument.<br />

Record-low ozone (O3) column <strong>de</strong>nsities (with a minimum<br />

of 212 DU) persisted over three weeks at the Rio Gallegos<br />

NDACC station in November 2009. The statistical analysis<br />

of 30 years of satellite <strong>da</strong>ta from the Multi Sensor Reanalysis<br />

(MSR) <strong>da</strong>tabase for Rio Gallegos revealed that such a<br />

long-lasting, low-ozone episo<strong>de</strong> is a rare occurrence. This<br />

statistical analysis reveals that 3% of events only correspond<br />

to 4 or more consecutive <strong>da</strong>ys with total ozone column below<br />

two stan<strong>da</strong>rd <strong>de</strong>viations of the <strong>da</strong>ily climatological mean<br />

(Wolfram et al., 2012).<br />

The effect of UV, as well as potentially harmful to<br />

marine life, may also increase the toxic effects of some<br />

contaminants such as petroleum hydrocarbons, commonly<br />

present in the vicinity of research stations. A recent study<br />

has <strong>de</strong>monstrated that mortality of marine crustacean<br />

Antarctic Amphipod Gondogeneia, subjected to the effects<br />

of anthracene, significantly increased in the presence of<br />

UV (Gomes et al., 2009), reinforcing the importance of<br />

un<strong>de</strong>rstanding the biological responses of species to the<br />

synergistic action the various natural and anthropogenic<br />

environmental factors.<br />

Over the past 65 years, average annual temperatures<br />

of the air in Admiralty Bay show an average warming of<br />

+0.23 °C. However, one must consi<strong>de</strong>r that this region’s<br />

climatological measurement was stan<strong>da</strong>rdized only in<br />

the last 30 years and the <strong>da</strong>ta from this period does not<br />

indicate a warming climate. Over the past 14 years, average<br />

annual temperatures recor<strong>de</strong>d in the air at EACF showed<br />

a downward trend (≈ –0.6 °C / <strong>de</strong>ca<strong>de</strong>, Setzer et al., 2009).<br />

According to the researcher teams weather recordings, the<br />

winters of 2007 and 2009 were very severe, freezing the<br />

two lakes that feed EACF and the amount of ice covering<br />

Admiralty Bay peaked with frozen sea to the vicinity of<br />

the Polish Station, near the entrance to the Bay. January<br />

and February 2010 registered the col<strong>de</strong>st summer months<br />

recor<strong>de</strong>d in EACF in the last 37 years (mean air temperature<br />

+1.0 °C in January and +0.2 °C in February).<br />

Abstract: Here we present the ionosphere behavior obtained from measurements done with the ionoson<strong>de</strong> operating at Coman<strong>da</strong>nte<br />

Ferraz Brazilian Antarctic Station (EACF) in 2011. We also discuss its long-term behavior obtained from 2004 to 2011 using very<br />

low frequency radio signals and GPS measurements. During quiet periods the ionosphere is controlled by the solar Lyman alpha<br />

radiation, presenting variations closely associated with the 11-year sunspot number. But it is strongly affected by the excess of<br />

X-ray emission produced during the solar flares. The long-term studies of ionosphere behavior have also shown it presents strong<br />

variations during local wintertime, which were found to be closely related to the waves of neutral atmospheric origin. The studies<br />

of ionosphere behavior have been improving our un<strong>de</strong>rstanding of its response to natural phenomena, and about its coupling<br />

with the other atmospheric layers. The energy exchange among atmospheric layers might be an important factor in the climate<br />

conditions/changes, which affect the terrestrial and marine environment, especially in the polar region.<br />

Keywords: atmosphere, sun-earth interaction, atmospheric radio sounding<br />

Introduction<br />

The ionosphere is formed/maintained by the solar<br />

Lyman-alpha (121.5 nm) ionizing radiation during quiet<br />

conditions (Nicolet & Aikin, 1960). This solar radiation<br />

presents variability in close association with the 11-year<br />

solar cycle, which affects the ionization processes of the<br />

low ionosphere (Lastovicka, 2006). This effect has been<br />

obtained from long-term measurements of very low radio<br />

frequency (VLF) signals propagating over long distances<br />

insi<strong>de</strong> the Earth-ionosphere wavegui<strong>de</strong> during the 22 nd and<br />

23 rd solar cycles (Thomson & Clilverd, 2000; Correia et al.,<br />

2011, respectively). Since the maximum of the 24 th solar<br />

cycle will be during 2013-2014, the influence of the solar<br />

radiation in our atmosphere will increase in the next two<br />

years due to changes in its chemistry and physics produced<br />

by ionization process enhancements.<br />

The ionosphere is also strongly affected by upward<br />

propagating gravity and planetary waves originated in the<br />

neutral atmosphere particularly during the local wintertime<br />

(Lastovicka, 2006). The effects of planetary waves were<br />

<strong>de</strong>tected in the VLF measurements done from 2004-2011<br />

at Coman<strong>da</strong>nte Ferraz Brazilian Antarctic Station (EACF)<br />

(Correia et al., 2011, 2013). The atmospheric waves have an<br />

important role in the energy and momentum transport from<br />

the lower to upper atmosphere layers, affecting the thermal<br />

structure and general circulation in the middle and upper<br />

atmosphere (Takahashi et al., 1999; Bageston et al., 2011).<br />

The year-to-year variation in ozone holes are also affected<br />

by differences in atmospheric temperature and circulation<br />

(e.g. Newman et al., 2008).<br />

Here we present the solar activity in 2011 and its<br />

influence in the ionosphere obtained from ionoson<strong>de</strong><br />

measurements done at EACF. Recent scientific results<br />

related to ionospheric behavior from 2007 to 2011 obtained<br />

with VLF measurements done at EACF and at Itapetinga<br />

Radio Observatory (ROI, Atibaia/Brazil), and from 2004 to<br />

2011 obtained with GPS system operating at EACF are also<br />

presented and discussed.<br />

Materials and Methods<br />

The ionosphere behavior is obtained using different radio<br />

sounding techniques:<br />

VLF measurements are done in the 1-50kHz frequency<br />

range with 20ms time resolution using Atmospheric Weather<br />

Electromagnetic systems for Observation, Mo<strong>de</strong>ling and<br />

Education receivers - AWESOME (Scherrer et al., 2008)<br />

operating at EACF (62.11° S and 58.41° W, since 2007) and<br />

at ROI (23.21° S and 46.51° W, since 2006). VLF technique is<br />

used to study the lower part of the ionosphere, the D-region<br />

that is between 60 and 85 km of height.<br />

The Vertical Total Electron Content (VTEC) of<br />

ionosphere is obtained using dual-frequency GPS receivers.<br />

The phase shifts produced by the dispersive nature of the<br />

plasma are directly proportional to VTEC, which is the<br />

integral line of the electron concentration along the path<br />

between the satellite and receiver. The ionosphere has been<br />

monitored at EACF since 2004 using a Javad GPS receiver<br />

with a best time resolution of 1s. VTEC is estimated using<br />

the first step of the Implementation of La Plata Ionospheric<br />

Mo<strong>de</strong>l (LPIM) applicative <strong>de</strong>veloped in the National La Plata<br />

University (Argentine) (Brunini et al., 2008).<br />

The ionosphere at EACF has also been monitored<br />

since 2009 using a Canadian Digital Ionoson<strong>de</strong> (CADI,<br />

MacDougall, 1997) that consists of one transmitter at<br />

frequencies between 1 and 20 MHz, and four receivers to<br />

<strong>de</strong>tect the reflected signals. The echoes of the reflected signal<br />

by the F and E regions of the ionosphere provi<strong>de</strong> a profile of<br />

reflection frequency versus virtual height (ionogram), which<br />

gives information of the electron <strong>de</strong>nsity (directly related<br />

to the reflection frequency) profile as a function of actual<br />

height (Piggott & Rawer, 1972). The CADI is programmed<br />

to obtain ionograms each 5min and drift measurements<br />

each 2.5 min. The scaling of ionograms is obtained using<br />

the software <strong>de</strong>veloped at Universi<strong>da</strong><strong>de</strong> do Vale do Paraíba<br />

(UNIVAP) called the UNIVAP Digital Ionoson<strong>de</strong> Data<br />

Analysis (UDIDA) (Fagun<strong>de</strong>s et al., 2005).<br />

Results<br />

Solar activity in 2011<br />

We are in the ascending phase of the 24 th solar cycle, which<br />

started at the beginning of 2010 and which will reach its<br />

maximum during 2013-2014 as shown by the solar cycle<br />

sunspot progression presented in the Figure 1a (http://<br />

www.swpc.noaa.gov/SolarCycle/, access: 22 May 2102).<br />

To evaluate the solar influence in the ionosphere on 2011<br />

we compared the foF2 parameter, which gives information<br />

about the electron <strong>de</strong>nsity at ~200 km of height, with the<br />

<strong>da</strong>ily sunspot number (Rz, http://sidc.oma.be/sunspot<strong>da</strong>ta/,<br />

access: 21 May 2012) (Figure 1b). The foF2 here is<br />

the F2 layer critical frequency parameter estimated from<br />

ionograms at ~16:00 UT (local noon time) obtained from<br />

CADI measurements done at EACF. The foF2 parameter<br />

shows that the ionosphere electron <strong>de</strong>nsity changed in close<br />

association with the solar activity variation, presenting two<br />

peaks (April and November) that are present in the Rz <strong>da</strong>ta<br />

and a similar increase ten<strong>de</strong>ncy during the year.<br />

The effect of the increasing solar activity in the low<br />

ionosphere was also evaluated from the phase variations<br />

of VLF signals, particularly from correlation between the<br />

phase variations and the intensity of the X-ray flares. The<br />

intensity of the X-ray flares able to produce significant VLF<br />

phase variations increased from ≥ 3.0 × 10 –7 W/m 2 during<br />

the solar minimum (2007-2009), to ~3.8 × 10 –7 W/m 2 and<br />

to 4.2 × 10 –7 W/m 2 , respectively in 2010 and 2011.<br />

Ionosphere long-term behavior –<br />

VLF measurements<br />

The study of the solar forcing in the ionosphere using<br />

the <strong>da</strong>ytime VLF amplitu<strong>de</strong> was done for the 2007-2011<br />

period consi<strong>de</strong>ring the VLF signals transmitted from NPM<br />

(Hawaii) and NAA (North Dakota) and received at EACF<br />

and ROI (Correia et al., 2013). The results, as expected,<br />

show the solar Lyman-alpha radiation (http://lasp.colorado.<br />

edu/lisird/lya/) control on the lower ionosphere, which<br />

was characterized by the VLF amplitu<strong>de</strong> <strong>de</strong>cline from<br />

2007 to 2009, when the 23 rd solar cycle reached its lowest<br />

activity level, followed by an increasing ten<strong>de</strong>ncy with<br />

the starting of activity of the 24 th solar cycle (Figure 2).<br />

This result is in agreement with Correia et al. (2011), who<br />

obtained a good correlation during the <strong>de</strong>cay phase of the<br />

23 rd solar cycle (2004-2008). The <strong>da</strong>ytime VLF amplitu<strong>de</strong><br />

also showed high <strong>da</strong>y-to-<strong>da</strong>y variations, which present a<br />

clear seasonal behavior occurring predominantly during<br />

local wintertime in all years. The VLF amplitu<strong>de</strong> variations<br />

indicated a significant component in a 16-<strong>da</strong>y period, typical<br />

of planetary waves of stratosphere/tropospheric origin.<br />

GPS measurements<br />

The ionosphere behavior was evaluated from the study of<br />

monthly VTEC variations observed at EACF from 2004 to<br />

2011 (Figure 3a). The analysis shows that VTEC presents<br />

a seasonal variation produced by the solar illumination,<br />

which slowly changes in close association with 11-year solar<br />

cycle as shown by the variation of the Ultraviolet radiation<br />

(30.4 nm, http://lasp.colorado.edu/lisird/lya/). This good<br />

correlation between VTEC and solar UV variation at local<br />

summer (January) and winter (July) seasons are clearly<br />

seen in Figure 3b.<br />

Discussion and Conclusion<br />

The Sun is the main energy source on Earth, being<br />

responsible for its environmental conditions and for life.<br />

On the other hand, the atmosphere is also an important<br />

element that filters part of the solar radiation that is harmful<br />

to terrestrial and marine life, especially in X-rays and<br />

ultraviolet spectral range. Solar radiation is not constant and<br />

presents variations in different time scales, mainly associated<br />

with the Gleissberg cycle (~90 years), Hale cycle (~22 years)<br />

and Schwabe cycle (~11 years), as well as with 27-<strong>da</strong>ys time<br />

scale associated with the solar rotation.<br />

The more pronounced solar variations occur in an<br />

11-year cycle, which is the main driver of the Earth´s<br />

atmospheric conditions, as evi<strong>de</strong>nced from long-term<br />

ionospheric studies and reinforced by the VLF amplitu<strong>de</strong><br />

increase observed during 2011 in close association with<br />

the enhancement of the 24 th solar cycle activity. Variations<br />

in shorter time scales (minutes to hours) occur in close<br />

association with the solar flares, whose excess of X-ray<br />

emission strongly affects the lower ionosphere. As the Sun<br />

becomes more active, the solar radiation increases and<br />

alters the atmosphere’s chemistry and physics influencing<br />

the environmental conditions, and thus the terrestrial and<br />

marine life.<br />

The studies have also shown that the upper atmosphere<br />

is also affected by atmospheric waves of troposphere/<br />

stratosphere origin. These waves in their upward propagation<br />

strongly affect the ionosphere, especially during the<br />

local wintertime, evi<strong>de</strong>ncing a coupling between all<br />

atmospheric layers. Thus, the simultaneous monitoring of<br />

the atmospheric layers is important for un<strong>de</strong>rstanding how<br />

the solar energy input is transported to lower atmosphere<br />

layers, and to <strong>de</strong>fine the role of solar radiation in the climate<br />

changes.<br />

In the next two years this monitoring will be very<br />

important because the 24 th solar cycle will reach its<br />

maximum activity, and the solar energy input in our<br />

atmosphere will be at its highest level.<br />

Abstract: The upper atmosphere above the Sub-Antarctic Islands and Drake Passage is abun<strong>da</strong>nt in gravity waves from the<br />

troposphere up to the mesosphere. Satellite <strong>da</strong>ta and ground based instruments have <strong>de</strong>monstrated this high gravity wave<br />

activity in these regions. Since 2010 an all sky airglow imager has observed gravity waves through the OH NIR airglow emission<br />

(~87 km height) over Coman<strong>da</strong>nte Ferraz Antarctic Station (62° S) on King George Island. A new-generation meteor ra<strong>da</strong>r<br />

was installed on that site in 2010 and has been operated simultaneously with an OH airglow imager. The <strong>da</strong>ta set of airglow<br />

images from 2010 and 2011 is un<strong>de</strong>r analyses, and the results from 2010 showed similar characteristics for the waves reported<br />

in a campaign carried out in 2007. This work will present the observational results for the gravity waves observed in 2010 and<br />

2011 above King George Island. These results are composed by the observational statistics for 2010 and 2011, and the observed<br />

wave parameters and the preferable propagation directions for the events observed during 2010.<br />

Keywords: airglow, atmospheric gravity waves, wave characteristics<br />

Introduction<br />

The dynamics of the polar mesosphere and lower<br />

thermosphere (MLT) are dominated by waves with periods<br />

ranging from a few minutes to months (Hibbins et al., 2007).<br />

Gravity waves are now recognized to play an important role<br />

in the general circulation of the middle atmosphere. Forcing<br />

by gravity waves causes reversals of the zonal mean jets and<br />

drives a mean meridional transport circulation that leads<br />

to a latitudinal temperature gradient opposite to that which<br />

would be expected in the absence of wave forcing (Fritts<br />

& Alexan<strong>de</strong>r, 2003). Espy et al. (2004) reported seasonal<br />

variations in the gravity wave momentum flux over Halley<br />

Station, Antarctica (75.6° S and 26.6° W). They used <strong>da</strong>ta<br />

from a sodium airglow imager and an Imaging Doppler<br />

Interferometer (IDI) ra<strong>da</strong>r for wind measurements. The<br />

authors showed a significant <strong>da</strong>y-to-<strong>da</strong>y variability in the<br />

momentum flux, with a strong westward momentum flux<br />

that turned eastward around the equinox. Nielsen et al.<br />

(2006) used an all-sky imager at Halley Station to show the<br />

first bore event observed at high latitu<strong>de</strong>s. Bageston et al.<br />

(2009) presented the first airglow observations at Ferraz<br />

Station (62.1° S and 58.4° W) based on a full winter <strong>da</strong>ta<br />

set. They showed the wave parameters distribution and<br />

preferable propagation directions for the waves i<strong>de</strong>ntified<br />

during the austral winter of 2007. Climatology of gravity<br />

waves above Halley Station was reported by Nielsen et al.<br />

(2009), using airglow <strong>da</strong>ta of two consecutive austral winters<br />

(2000 and 2001) and including local hourly winds and<br />

intrinsic wave parameters. This paper present results for two<br />

consecutive austral winters above Ferraz Station (62.1° S,<br />

58.4° W), including example of wave events, statistics of the<br />

observations and the observed wave characteristics.<br />

Materials and Methods<br />

The <strong>da</strong>ta used in this work inclu<strong>de</strong>s all-sky airglow images,<br />

from which it is possible to i<strong>de</strong>ntify small and mediumscale<br />

waves in the upper mesosphere. The observed airglow<br />

emission is the hydroxyl in the near infrared spectrum (OH<br />

NIR, 715–930 nm), with emission peak around 87 km high.<br />

Small-scale gravity waves can be i<strong>de</strong>ntified in Figure 1 in<br />

original all-sky images obtained in May 2010 and August<br />

2011. The images are aligned N-S (top-bottom) and E-W<br />

(left-right) and boxes were drawn in or<strong>de</strong>r to i<strong>de</strong>ntify an<br />

arbitrary region of wave activity since we can see wave<br />

activity over a large area in the images.<br />

The methodology used to analyze airglow images and<br />

obtain the wave parameters was revised by Wrasse et al.<br />

(2007). They <strong>de</strong>scribe the main steps of the imaging<br />

pre-processing and spectral analysis used to obtain the<br />

wave parameters. The first stage is to align the top of the<br />

images with the geographic north, followed by the stars<br />

filtering from images in or<strong>de</strong>r to eliminate the spectral<br />

contamination at the high frequencies (Maekawa, 2000). The<br />

third step consists in mapping the image into the geographic<br />

coordinates, i.e, the images are corrected (unwarped) for the<br />

lens function calibration. The last stage of the imaging preprocessing<br />

is the application of a second or<strong>de</strong>r Butterworth<br />

filter (Bageston et al., 2011). Previous to the wave analysis<br />

(spectral analysis), it is necessary to select one gravity wave<br />

event easily i<strong>de</strong>ntified in a set of airglow images. Then, it is<br />

necessary to animate the images in or<strong>de</strong>r to recognize and<br />

select the interested region of the image where the event is<br />

appearing clearly. The last step in the wave analysis is the<br />

application of the bidimensional Fast Fourier Transform<br />

(FFT-2D) in the selected region which contains the wave<br />

event (Wrasse et al., 2007; Bageston, 2010).<br />

Results<br />

The results already obtained are the observation statistics for<br />

2010 and 2011, and observed wave parameters for the waves<br />

i<strong>de</strong>ntified in 2010. The statistical results revealed that among<br />

81 observed nights in 2010 we could i<strong>de</strong>ntify wave events<br />

in 31 nights with a total of 74 wave events, while in 2011 we<br />

had observations during 123 nights and in 52 of them it was<br />

possible to i<strong>de</strong>ntify 149 wave events. The difference in the<br />

observational statistics between the two years is mainly due<br />

to the time required for the installation of the meteor ra<strong>da</strong>r<br />

and the time spend for the installation of the airglow camera<br />

in 2010. Furthermore, the all-sky airglow camera started<br />

operating automatically only in May of 2010, while in 2011<br />

the beginning of systematic observations was in March. We<br />

should emphasize that we had several technical problems<br />

in the automatic mo<strong>de</strong> of <strong>da</strong>ta acquisition, causing a lower<br />

number of useful nights than would be expected consi<strong>de</strong>ring<br />

the length of the austral winter and its long nights.<br />

The observed characteristics for the waves i<strong>de</strong>ntified in<br />

2010 above Ferraz Station are presented in Figure 2. The<br />

horizontal wavelength, observed period and phase speed<br />

are in panels (a), (b) and (c), respectively. The intrinsic wave<br />

parameters will be estimated later, together with the results<br />

of 2011 (now un<strong>de</strong>r analysis). The horizontal wavelengths<br />

were distributed from 10 to 60 km, with a maximum<br />

occurrence between 20 and 40 km. The observed periods<br />

were distributed from 5 up to 60 minutes, with a maximum<br />

occurrence between 5 and 15 minutes. The observed phase<br />

speed has a distribution that extends from 0 to higher than<br />

70 m/s, and the majority of the waves had velocities between<br />

10 and 40 m/s. The results presented in Figure 2 are very<br />

similar to the observations reported previously for Antarctic<br />

latitu<strong>de</strong>s (Bageston et al., 2009; Nielsen et al., 2009), with<br />

slight differences in the phase speed distribution and<br />

basically the same characteristics regarding the horizontal<br />

wavelength and observed period.<br />

anisotropy, with most of the waves propagating to the<br />

seen propagating to the south and southwest. The results on<br />

the propagation direction of gravity waves are mainly related<br />

with the location of the gravity wave sources and also to the<br />

winds filtering processes below the airglow emission layer.<br />

Discussion and Conclusion<br />

The present work showed the statistics and characteristics of<br />

the gravity waves observed at Coman<strong>da</strong>nte Ferraz Antarctic<br />

Station (62.1° S and 58.4° W) during the austral winters of<br />

2010 and 2011. We presented the wave characteristics and<br />

propagation directions for the waves i<strong>de</strong>ntified in 2010.<br />

These results are similar to previous observations in Ferraz<br />

Station and in other sites around the Antarctic continent.<br />

The characteristics of the waves i<strong>de</strong>ntified during<br />

2011 are currently being analyzed, and the intrinsic wave<br />

parameters will be obtained for the full <strong>da</strong>ta set by using<br />

local mesospheric winds as obtained by a meteor ra<strong>da</strong>r.<br />

Future investigations will focus on gravity wave sources<br />

in the lower atmosphere through the reverse ray tracing<br />

mo<strong>de</strong>l, which makes use of the observed wave parameters,<br />

mesospheric winds obtained by meteor ra<strong>da</strong>r and mo<strong>de</strong>ls,<br />

temperatures <strong>de</strong>rived from satellite and reanalysis <strong>da</strong>ta, and<br />

meteorological satellite images.<br />

Abstract: During spring, poor ozone air masses can come out of the Antarctic Ozone Hole and reach mid and low latitu<strong>de</strong> areas<br />

like the South of Brazil forming a known phenomenon called “Secon<strong>da</strong>ry Effects of the Antarctic Ozone Hole”. One of these<br />

phenomena was observed on October, 13 th , 2010, by OMI Spectrometer over Southern Space Observatory (29.42° S and 53.87° W),<br />

in São Martinho <strong>da</strong> Serra, Brazil. Stratospheric potential vorticity maps on isentropic surfaces and air mass backward trajectory<br />

using HYSPLIT mo<strong>de</strong>l by NOAA confirmed the polar origin of the poor ozone air mass. A <strong>de</strong>scription of the synoptic weather<br />

system during the event was ma<strong>de</strong> by wind field <strong>da</strong>ily average at 250 hPa level and Omega at 500 hPa, thickness between 1000<br />

and 500 hPa levels and GOES 10 enhance satellite image. It was observed that the event of low ozone occurred at the same time<br />

as a high pressure pos frontal system was passing over the south of Brazil and the subtropical jet stream left the weather stable<br />

and without clouds. These actions favored the intrusion of the stratospheric air in the troposphere and helped the stratospheric air<br />

mass transport from the polar region to the South of Brazil.<br />

Keywords: ozone, Antarctic ozone hole, potential vorticity, synoptic analysis<br />

Introduction<br />

The Antarctic continent shows a very low content of ozone<br />

layer during the spring of every year, the Antarctic Ozone<br />

Hole (Farman et al., 1985; Solomon, 1999). However, its<br />

effects were not limited to the Polar Region, since poor<br />

ozone air mass could come out of the polar vortex and reach<br />

mid and low latitu<strong>de</strong> (Prather & Jaffe, 1990), temporarily<br />

reducing the ozone layer. This phenomenon was first<br />

observed over South of Brazil by Kirchhoff et al. (1996). The<br />

relationship between ozone concentration and the passage of<br />

a synoptic weather system is not well known and it is being<br />

consi<strong>de</strong>red a new line of research for ozone (Ohring et al.,<br />

2010), which motivated this work.<br />

Methodology<br />

Events of influence of the Antarctic ozone hole over the<br />

south of Brazil were <strong>de</strong>tected by analysis of ozone total<br />

column, obtained by an OMI Spectrometer installed in<br />

a satellite, over the Southern Space Observatory – OES/<br />

CRS/CCR/INPE-MCTI (29.42° S and 53.87° W), in São<br />

Martinho <strong>da</strong> Serra, Brazil. Days with ozone total column<br />

<strong>da</strong>ily average inferior to the monthly climatological mean<br />

less 1.5 its stan<strong>da</strong>rd <strong>de</strong>viation (µ – 1,5σ) were analyzed. For<br />

these <strong>da</strong>ys, the variation of the absolute potential vorticity<br />

on isentropic surfaces maps at 620 K level of potential<br />

temperature were calculated with <strong>da</strong>ily parameters from<br />

NCEP/NCARreanalysis using GRADS. Air mass backward<br />

Results<br />

In this work, the example of the event that occurred on<br />

October, 13 th , 2010 was used, when the ozone total column<br />

was 276.1 DU, a reduction of 5.6% over the October<br />

climatological mean which was 292,7 ± 10.2 DU. The<br />

air mass with poor ozone reached the South of Brazil on<br />

October, 12 th , as can be observed at Figure 1, when there<br />

occurred an increase at the Absolute Potential Vorticity<br />

at 620 K level of potential temperature from 11 th (a) to<br />

12 th (b) and higher on the 13 th (c), this last <strong>da</strong>y registering<br />

the lowest ozone total column in the period, confirming the<br />

polar air mass origin by backward trajectory (d) and ozone<br />

image from OMI satellite (e), showing the influence of the<br />

Antarctic ozone hole over the South of Brazil.<br />

Because of the poor ozone air mass arrival over the South<br />

of Brazil on October, 12 th , 2010, the synoptic weather system<br />

was analyzed for this <strong>da</strong>y, when action of the subtropical jet<br />

stream polar entry could be observed at 250 hPa level and<br />

level, which was observed at Figure 2a. Furthermore, the<br />

action of an intense high pressure pos frontal system at sea<br />

level (Figure 2b) over the region was observed, getting the<br />

South of Brazil with stable weather with no cloudiness as<br />

can be observed through the satellite image (Figure 2c).<br />

stream over the region caused intrusion of the stratospheric<br />

air into the troposphere (Stohl et al., 2003). This pattern had<br />

an important role at vertical distribution and total content<br />

of ozone layer (Bukin et al., 2011), enhancing the transport<br />

of air mass from polar region towards South America and<br />

the South of Brazil and probably helped poor ozone air<br />

mass transport.<br />

Discussion and Conclusion<br />

The <strong>de</strong>crease in ozone total column of 5.6% less than the<br />

October climatological average which occurred on October,<br />

13 th , 2010 was due to an influence of the Antarctic ozone<br />

hole over the South of Brazil checked through the increase<br />

in Absolute Potential Vorticity indicates the polar origin of<br />

the stratospheric air mass with poor ozone (Semane et al.,<br />

2006) and confirmed by air mass backward trajectory<br />

(Gupta et al., 2007) and ozone image from OMI satellite<br />

in a manner analogous to events found by (Pinheiro et al.,<br />

2011). The synoptic weather system acting during the event<br />

was a high pressure pos frontal system at sea level, indicated<br />

subsi<strong>de</strong>nt movement of the air over the South of Brazil,<br />

which associated with the passage of the subtropical jet<br />

Abstract: The Antarctic Ozone Hole is a cyclical phenomenon, which occurs over the Antarctic region from August to December<br />

each year. The polar vortex turns it into a restricted characteristic dynamics for this region. However, from time to time, some<br />

air masses with low ozone concentration could escape and reach regions of lower latitu<strong>de</strong>s. The aim of this study is analyzed the<br />

influence of the Antarctic Ozone Hole over the South of Brazil in the years 2010 and 2011. To verify these events, ozone total<br />

column from OMI Spectrometer overpass <strong>da</strong>ta for the coordinates of Southern Space Observatory (29.42° S and 53.87° W), in<br />

São Martinho <strong>da</strong> Serra, South of Brazil was used. In addition to OMI <strong>da</strong>ta, potential vorticity maps using GrADS (Grid Analysis<br />

and Display System) generated with the NCEP reanalysis <strong>da</strong>ta and air mass backward trajectories, using the HYSPLIT mo<strong>de</strong>l of<br />

NOAA, were analyzed. Ozone total column for the <strong>da</strong>ys with low ozone were compared with monthly climatological average from<br />

1981 to 2011. Consi<strong>de</strong>ring only the <strong>da</strong>ys with ozone lower than climatological means minus 1.5 stan<strong>da</strong>rd <strong>de</strong>viation, increased<br />

absolute potential vorticity and backward trajectories indicating the origin of polar air masses, 4 events in 2010 and 3 events in<br />

2011, with an average <strong>de</strong>creased about 6.3 ± 2.1% when compared with climatological means, were observed in the period analyzed.<br />

Keywords: mid-latitu<strong>de</strong>, potential vorticity, backward trajectories, Antarctic ozone hole<br />

Introduction<br />

Potential Vorticity (PV) has an important hole at air<br />

mass dynamic movement, having a behavior like a<br />

material surface where potential temperature is preserved<br />

(Hoskins et al., 1985), being used in studies correlating PV<br />

and trace gases like ozone and water vapour over isentropic<br />

surfaces in low stratosphere (Danielsen, 1968). The domain<br />

of the Antarctic polar vortex and its filaments was <strong>de</strong>fine as<br />

being the region with high PV gradient, where air masses<br />

with lower PV than the boun<strong>da</strong>ry of the outsi<strong>de</strong> region<br />

were inclu<strong>de</strong>d insi<strong>de</strong> the vortex, conserving differences<br />

chemical characteristics, and the center of the vortex with<br />

the minimum PV region or maximum Absolute PV (APV)<br />

(Marchand et al., 2005). The PV variation over isentropic<br />

surfaces can be used to transport ozone in stratosphere<br />

(Jing et al., 2005). An increase at the APV indicated a polar<br />

origin of the poor ozone air mass (Narayana Rao et al., 2003;<br />

Semane et al., 2006). The polar origin of an air mass can be<br />

show also with backward trajectories (Gupta et al., 2007).<br />

Although the stability of the polar vortex, air masses could<br />

come out of its filaments and reach mid and low latitu<strong>de</strong>s,<br />

causing a temporary <strong>de</strong>crease in ozone concentration.<br />

Prather & Jaffe (1990) calculated that Antarctic air masses<br />

could be isolated for 7 to 20 <strong>da</strong>ys after their separation of<br />

the vortex, time sufficient to propagate toward mid and low<br />

latitu<strong>de</strong>s. This phenomenon was first observed over South<br />

of Brazil by Kirchhoff et al. (1996).<br />

Materials and Methods<br />

Events of Antarctic ozone hole influence over South of Brazil<br />

in 2010 and 2011 were <strong>de</strong>tected using overpass <strong>da</strong>ta of ozone<br />

total column from Ozone Monitoring Instrument (OMI)<br />

insi<strong>de</strong> ERS-2 satellite for Southern Space Observatory -<br />

SSO/CRS/INPE - MCTI (29.4° S and 53.8° W; 488.7 m), in<br />

South of Brazil. OMI ozone total column was compared with<br />

monthly climatological averages from 1981 to 2011 obtained<br />

by Brewer Spectrophotometer, installed at SSO, Total<br />

Ozone Mapping Spectrometer (TOMS), inboard Nimbus-7,<br />

Meteor-3 and Earth Probe, National Aeronautics and Space<br />

Agency (NASA) satellites, and OMI from 2006. For the<br />

<strong>da</strong>ys with ozone total column lower than climatological<br />

average minus 1.5 stan<strong>da</strong>rd <strong>de</strong>viation, isentropic analysis<br />

using Potential Vorticity maps were ma<strong>de</strong> with National<br />

Centers for Environmental Prediction/Atmospheric<br />

Research (NCEP/NCAR) reanalysis <strong>da</strong>ta (http://www.cdc.<br />

noaa.gov/cdc/reanalysis/reanalysis.shtml). These PV maps<br />

were generated with GrADS (Grid Analysis and Display<br />

System). The analysis verifies if there was an increase at<br />

Absolute Potential Vorticity, indicated the polar origin of the<br />

ozone poor air mass. The confirmation of the polar origin<br />

can be obtained by air masses backward trajectories using<br />

HYSPLIT (HYbrid Single-Particle Lagrangian Integrated<br />

Trajectory) mo<strong>de</strong>l, <strong>de</strong>veloped by National Oceanic and<br />

Atmospheric Agency (NOAA) and Australia‘s Bureau of<br />

Meteorology (http://www.arl.noaa.gov/ready/open/traj.<br />

Results<br />

Monthly Climatological averages of ozone total column<br />

measured by Brewer Spectrophotometer, TOMS and OMI<br />

for Southern Space Observatory from 1981 to 2011 were<br />

291.9 ± 12.5 DU for August, 298.3 ± 9.8 DU for September<br />

and 292.8 ± 10.1 DU for October. The <strong>da</strong>ys of 2010 and 2011<br />

with ozone total column lower than these climatological<br />

averages minus 1.5 times the stan<strong>da</strong>rd <strong>de</strong>viation was<br />

analyzed according to the methodology <strong>de</strong>scribed above.<br />

The examples of October, 22 th 2010 and October, 21 th 2011<br />

are shown in Figure 1 and Figure 2, respectively, where an<br />

increase of absolute potential vorticity at the level of 620 K<br />

(a), the backward trajectories of air masses poor of ozone<br />

(b) and OMI <strong>da</strong>ta (c) are represented showing the influence<br />

of Antarctic Ozone Hole over South of Brazil. Consi<strong>de</strong>ring<br />

only the <strong>da</strong>ys with <strong>de</strong>creased ozone measured at Southern<br />

Space Observatory, increased absolute potential vorticity<br />

shown at GRADS maps and HYSPLIT backward trajectories<br />

indicating the origin of polar air masses, it was observed 4<br />

events in 2010 and 3 events in 2011 presented at Table 1, with<br />

an average <strong>de</strong>creased about 6.3 ± 2.1% when compared with<br />

climatological means.<br />

Discussion<br />

Similar events of low ozone air masses intrusions from<br />

Antarctic ozone hole toward mid latitu<strong>de</strong> like those analyzed<br />

here were also observed over South America (Kirchhoff et al.,<br />

1996; Perez et al., 2000), Southern Africa (Semane et al., 2006)<br />

Abstract: In this work the diurnal evolution of the energy balance at the surface is estimated for the King George Island, based on in<br />

situ observations of net radiation, soil heat flux and vertical profiles of wind speed, air temperature and specific humidity measured<br />

at the South Tower in the Brazilian Antarctic Station Coman<strong>da</strong>nte Ferraz. The turbulent fluxes were estimated by adjusting vertical<br />

profiles expressions based on the Monin-Obukhov Similarity Theory. The diurnal evolution of the energy balance components at<br />

the surface indicates, during this period, that the large input of energy causes large imbalance in the surface energy balance. The<br />

imbalanced term, estimated also for other periods, seems to be related mainly to the heterogeneity of the land use and topography.<br />

Keywords: energy balance, sensible heat, latent heat and soil heat flux<br />

Introduction<br />

Quantifying interaction between surface and atmosphere<br />

through observation is one of the most challenging tasks<br />

ever. It evolves estimating exchange of energy, mass and<br />

momentum, simultaneously, in different places, facing<br />

heterogeneities inherent to the surface of the Earth at<br />

different meteorological scales. Among all ecosystems the<br />

one represented by Antarctica is most challenging given the<br />

extreme weather conditions prevailing during most of the<br />

time. These difficulties worsen in the case of the Brazilian<br />

Antarctic Station Coman<strong>da</strong>nte Ferraz because it is located<br />

on the shoreline region of the King George Island that is<br />

characterized by highly complex topography. Besi<strong>de</strong>s, the<br />

land cover is continuously changing by the temporal and<br />

spatial distribution of precipitation.<br />

The main goal of the ETA (“Estudo <strong>da</strong> Turbulência na<br />

Antártica”- Antarctica Turbulence Study) project is to<br />

estimate the energy fluxes of sensible and latent heat at<br />

the surface at the Brazilian Antarctic Station Coman<strong>da</strong>nte<br />

Ferraz using slow and fast response sensors (Oliveira et al.,<br />

2012). In this work the diurnal evolution of the energy<br />

balance components are estimated using in situ observations<br />

of net radiation and soil heat flux. Hourly values of turbulent<br />

fluxes were estimated using low response sensors to provi<strong>de</strong><br />

vertical profiles of wind speed, air temperature and specific<br />

humidity (Figure 1). Universal non dimensional vertical<br />

gradients, provi<strong>de</strong>d by the Monin-Obukhov Similarity<br />

Theory, were adjusted, by linear fitting technique, to the<br />

observed vertical profiles, yielding turbulent fluxes of<br />

sensible and latent heat.<br />

Materials and Methods<br />

Energy balance at the surface can be expressed as:<br />

Rn = G – H – LE + I<br />

Where Rn is the net radiation, G is the soil energy flux, H<br />

and LE are the turbulent energy fluxes of sensible and latent<br />

heat and I is the imbalanced term. The imbalanced term<br />

takes into account the energy fluxes that are not associated<br />

to local sources, systematic errors caused by observations<br />

In this work all energy fluxes are positive when oriented<br />

upwards and vice versa. Here, the year <strong>da</strong>y 52 (21 February<br />

2012) is used as example of the energy balance, because<br />

the weather conditions are not significantly disturbed on<br />

this <strong>da</strong>y.<br />

Results<br />

The soil temperature and the soil heat flux were obtained<br />

using, respectively, a soil temperature sensor and a soil heat<br />

flux plate set up at 5 cm below the surface (Figure 2).<br />

The sensible and latent heat fluxes were estimated<br />

using vertical profiles of wind velocity (Figure 3a, b), air<br />

temperature (Figure 3c) and specific humidity Figure 3d).<br />

Details of the sensors used here can be found in Oliveira et al.<br />

(2012) and Co<strong>da</strong>to et al. (2012).<br />

According to Monin-Obukhov Similarity Theory, the<br />

mean vertical profiles of horizontal wind speed, potential<br />

temperature and specific humidity can be expressed in<br />

terms of non dimensional universal relations (Wyngaard,<br />

2010). These functions <strong>de</strong>pend on the stability of the surface<br />

layer and can be used to estimate the characteristic scales<br />

of velocity (u *<br />

), temperature (θ *<br />

) and specific humidity (q *<br />

).<br />

The net radiation was estimated using a net radiometer<br />

(Figure 4) installed at south tower of the EACF.<br />

Where ρ is <strong>de</strong> air <strong>de</strong>nsity, c P<br />

pressure and L is the latent heat of vaporization.<br />

Discussion<br />

The major reason for the energy imbalance (Figure 5c, d) is<br />

that over heterogeneous landscape the turbulent exchange<br />

processes of larger scales cannot be captured by eddy<br />

covariance. Long wave and organized turbulence are not<br />

properly <strong>de</strong>scribed because most of the eddy covariance<br />

algorithms do not consi<strong>de</strong>r the covariance when the signal<br />

is non stationary, so that H+LE is un<strong>de</strong>restimated. Besi<strong>de</strong>s,<br />

due to wind direction high variability the foot print has to<br />

be taken into consi<strong>de</strong>ration properly in or<strong>de</strong>r to reduce the<br />

error in H and LE measurements.<br />

Another source of error is caused by phase difference<br />

between soil heat flux and surface temperature. Energy<br />

balance at the surface responds to the temperature and soil<br />

heat flux evolution in time at the surface, the later parameter<br />

is measured using heat plates at some <strong>de</strong>pth so that there is a<br />

significant phase and amplitu<strong>de</strong> difference between surface<br />

temperature and soil heat flux. Besi<strong>de</strong>s, soil heat plates<br />

always un<strong>de</strong>restimate the soil heat flux amplitu<strong>de</strong> due to the<br />

<strong>de</strong>flection of heat flux lines of the soil by introducing the<br />

plate with different thermal conductivity (Gao et al., 2010)<br />

Conclusion<br />

The diurnal evolution of the energy balance components<br />

at the surface indicates that in this particular period<br />

There is a substantial imbalance that may be related to the<br />

methodology used to estimate the turbulent fluxes (indirect<br />

method), lack of representativeness of the soil heat flux and<br />

advection of heat associated mainly to the heterogeneity of<br />

the land use and topography of the region of the Brazilian<br />

Antarctic Station Coman<strong>da</strong>nte Ferraz. The next step is to<br />

compare the indirect method with the eddy correlation<br />

method. This will be possible when the sonic anemometer<br />

Introduction<br />

The module theme “Global Change Impact on the Antarctic<br />

Environment,” which investigates the impact of global<br />

change on terrestrial environment, <strong>de</strong>velops a set of research<br />

areas thaw of Antarctica, to obtain <strong>da</strong>ta which help to<br />

explain the effects of environmental change on biological<br />

communities. Besi<strong>de</strong>s trying to un<strong>de</strong>rstand the dynamics<br />

of populations and their relationships.<br />

The study of vegetation <strong>de</strong>velops surveys to <strong>de</strong>scribe<br />

and map the plant communities in ice-free areas, aiming<br />

to un<strong>de</strong>rstand their evolution, the relationships with<br />

the soil microbial community and birds colony and the<br />

emission of greenhouse gases that contribute to global<br />

warming. With the <strong>da</strong>ta obtained are expected to contribute<br />

to the monitoring of ice-free ecosystems, assessing the<br />

possible environmental impacts by human occupation<br />

or natural phenomena. Based on this objective, was<br />

chosen two indicators, “plant biodiversity” and “plant<br />

cover”. The use of “plant biodiversity” as an indicator of<br />

environmental impacts, based on the fact that most plants<br />

that grow in ice-free areas of Antarctica can be classified<br />

into ornithocropróphylous or ornithocopróphobous. Soon,<br />

all changes that occur in bird populations will be reflected<br />

in the biodiversity of plant communities. The “plant cover”<br />

is important because the global changes are altering the ice<br />

cover in Antarctica, contributing to changing environments<br />

and expansion of ice-free areas. With the <strong>da</strong>ta obtained will<br />

be possible to i<strong>de</strong>ntify, locate and <strong>de</strong>scribe each plant every<br />

community. Through georeferencing of each community<br />

will be possible to prepare maps of vegetation, which can<br />

be compared with those <strong>de</strong>veloped in the period 1995-<br />

2012, thus allowing the assessment of the evolution of each<br />

community, and contribute to building methodologies for<br />

monitoring plant communities of ice-free areas. The study<br />

of soil microbial communities and the gases flow that<br />

contribute to global warming started in 2010/2011 will<br />

continue collecting <strong>da</strong>ta in the same areas associated with<br />

working on vegetation.<br />

The main goal of studying the distribution and dynamics<br />

of seabird populations is un<strong>de</strong>rstand the complex relations<br />

between populations and oceanic factors. Seabirds are useful<br />

as tools for un<strong>de</strong>rstand and monitor the effects of global<br />

change whereas they provi<strong>de</strong> a link between marine and<br />

terrestrial environments. It is, many population measures we<br />

obtain in land are reflection of conditions that the birds are<br />

experiencing off sea. Sea climate and productivity can affect<br />

the foraging efficiency of seabirds and affect their breeding<br />

<strong>de</strong>cisions. Seabirds are on the top of food webs, then, they<br />

reflect the status of all the levels above. As they rely on sea<br />

productivity – Zooplankton, Krill, fishes and squids – any<br />

abrupt changes on lower levels of the food webs can affect<br />

<strong>de</strong>mography parameters such as number of breeding pairs,<br />

survival, breeding success, breeding <strong>de</strong>sertion rates, and so<br />

on. All factors are connected: the productivity on Antarctic<br />

waters clearly <strong>de</strong>pends on the balance of sea-ice-sheets<br />

dynamic which is correlated to sea-surface warming, sea<br />

level pressure and wind regime shifts. All those changes can<br />

directly or indirectly influence seabirds.<br />

As a linkage between sea and land, seabirds drive the<br />

structure of terrestrial communities, be they microbial,<br />

plants, lichens or invertebrates, by “fertilizing” soils and<br />

inputting energy from the ocean on the land. Measure<br />

all those connections is necessary so the whole picture of<br />

terrestrial communities responses to global changes can<br />

be achieved.<br />

Furthermore, seabirds can forage far from breeding<br />

grounds, many reaching subantarctic waters at north or<br />

going south into the Antarctic Circumpolar Currents,<br />

as <strong>de</strong>monstrated by the study “Oceanic habitat use of an<br />

Antarctic Southern Giant Petrel population during breeding<br />

period”. Through geolocation techniques we were able to<br />

access the ocean areas used by the species. Giant Petrels<br />

were wi<strong>de</strong>spread, reaching latitu<strong>de</strong>s between 55° S and 77°<br />

S and longitu<strong>de</strong>s between 35° W and 80° W. By knowing<br />

the foraging areas of the species during summer is possible<br />

estimate how the population dynamics are responsive to<br />

ocean changes at such areas, which is one of the aims of the<br />

Thematic Area 2 about seabirds.<br />

The efforts to measure such relations start by measuring<br />

the seabird population dynamics. Many species are<br />

<strong>de</strong>creasing at West Antarctica, and the paper “Population<br />

fluctuation of Pygoscelis papua and Pygoscelis antarctica,<br />

Elephant Island, South Shetlands, Antarctica” is a good<br />

example of that. Both Penguin populations showed<br />

consistent <strong>de</strong>creases over the last 40 years at one icefree<br />

area on Elephant Island, possible as a response to<br />

climate and food availability shifts. By using current and<br />

past information about seabird populations, the studies<br />

“Responses of an Antarctic Kelp Gull Larus dominicanus<br />

reproductive population to climate change” and “Responses<br />

of an Antarctic Southern Giant Petrel population to climate<br />

change” verified that the populations of both species<br />

are responding to variations of temperature and climate<br />

change in<strong>de</strong>xes such as Antarctic Oscillation In<strong>de</strong>x (AOI)<br />

and Southern Oscillation In<strong>de</strong>x (SOI), though by different<br />

means. Gulls presented a quadratic response to the SOI,<br />

what seems to reflect that cooler or warm conditions can<br />

take the breeding population down, while Giant Petrel<br />

Linear responses to temperature, SOI and AOI indicates a<br />

trend of population growth un<strong>de</strong>r warm conditions.<br />

Abstract: Mapping is an activity which can register the occurrence of phenomenons related to land cover. There are several methods<br />

of map registry. In Antarctic areas, the mapping gives importance to registry of the land cover of plants in ice-free areas. The maps<br />

are tools to un<strong>de</strong>rstand the dynamics of plants in those areas. The Global Navigation Satellite System (GNSS) is an important<br />

tool to reach this objective, such as the plotting of georeference points in any place in the world including Antarctic locations. This<br />

study aims to contribute to the research of mapping in ice-free areas making a comparison with map builds for Hennequin Point<br />

and Keller Peninsula at King George Island, Antarctica. The study was carried out using GNSS L1/L2 and L1 receivers to record<br />

points in ice-free areas with plant coverage and post processing using specific software. The post processed <strong>da</strong>ta were exported to<br />

CAD software. With the points plotted, they were connected using polylines to draw the vegetation patches. The maps obtained were<br />

overlapped to i<strong>de</strong>ntify the growth or retraction between the patches. The resulting maps are presented. The results show differences<br />

between the patches sampled during different polar years. Probably, these divergences are due to the different methodologies used to<br />

obtain the points in these areas. To better un<strong>de</strong>rstand these variations, we need to produce more maps of the same place, obtained<br />

with the same methodologies or compare them using Satellite Images with high spatial resolution.<br />

Introduction<br />

Mapping is an application of the cartographic process<br />

over <strong>da</strong>ta collection or information to obtain a graphic<br />

presentation for several phenomenons in the landscape<br />

(IBGE, 1999). For this activity tools such Remote Sensing,<br />

Photogrammetrie, Photo Interpretation, GNSS and<br />

Geographical Information System (GIS) (Rocha, 2007),<br />

were used. A range of systems such GPS (Global Positioning<br />

System) and GLONASS (Global’naya Navigatsionnaya<br />

Sputnikowaya Sistema) (Leick, 2004) contributed to improve<br />

mapping in areas with difficult access. The systems permit<br />

obtaining the coordinates of the user in real time in any<br />

place in the World. The paper by Rudolph (1963) was one<br />

of the first studies that contained a schematic map of plant<br />

community (PC) distribution in the region of Halley Station,<br />

Victoria Land, Antarctica. Ochyra & Furmańczyk (1982)<br />

used the application of Remote Sensing by multispectral<br />

photography for <strong>de</strong>termining the distribution of PC near<br />

the Arctowski Station, King George Island. The resulting<br />

map was not georeferenced. Pereira & Putzke (1994) used<br />

techniques of mapping to <strong>de</strong>scribe the floristic composition<br />

of Stinker Point, Elephant Island, Antarctica. The study was<br />

based on i<strong>de</strong>ntification and mapping of the PC. The survey<br />

of the coastal ice-free area was un<strong>de</strong>rtaken by helicopter and<br />

i<strong>de</strong>ntified the floristic composition (Pereira & Putzke, 1994).<br />

The referred mapping was carried out through empiric<br />

observation and registered in a base map of that place. The<br />

GPS facilitated the making of points in these areas, since<br />

there is no need for the surveyor to measure distances,<br />

directions and altitu<strong>de</strong>s to obtain the coordinates for the<br />

points of study. This is the principle of Topographic survey<br />

(McCormac, 2007) which <strong>de</strong>mands several repetitions to<br />

complete. Pereira et al. (2007) carried out a study using<br />

GPS to reference the points in an aerial photographic survey<br />

to draw up a map with the distribution of the PC at King<br />

George Island, Antarctica.<br />

Materials and Methods<br />

Our study was conducted comparing two maps of two<br />

locations at Antarctic (Keller Peninsula – 62° 03’ 00”,<br />

62° 06’ 00” S and 58° 27’ 00”, 58° 21’ 00” W; Hennequin Point<br />

– 62° 05’ 00”, 62° 09’ 00” S and 58° 25’ 00”, 58° 16’ 00” W)<br />

both located at King George Island. At Keller Peninsula<br />

(KP), the study was conducted during the austral summer<br />

of 2002/2003 (Pereira et al., 2007) where some points<br />

were georeferenced using GPS for the aerial photographic<br />

survey. Based on the photographic survey the map with<br />

the distribution of the PC was drawn up. The second map,<br />

obtained through a survey making the contour of the PC,<br />

during the austral summer of 2009/2010 (Victoria et al,<br />

private communication), using a GPS L1 receiver able to<br />

obtain centimeter precisions while the <strong>da</strong>ta had to be post<br />

processed with the Astech Solutions® software. The two maps<br />

where overlapped and presented in Figure 1. At Hennequin<br />

Point (HP) the study was conducted during the austral<br />

summer of 2004/2005 (Victoria et al, unpublished) using<br />

the same GPS receiver used to obtain the last map KP. For<br />

the austral summer of 2010/2011 a GPS L1/L2 receiver to<br />

make the contour of the PC was used. The two maps were<br />

superposed and presented in the Figure 2.<br />

Results<br />

The results of the overlapped maps of Keller Peninsula were<br />

presented at the Figure 1. The contour of the vegetation<br />

patches, obtained at austral summer of 2002/2003 year<br />

were presented without hatch colors. The vegetation<br />

patches, obtained in austral summer of 2009/2010 year were<br />

Figure 1. Overlapped maps of Keller Peninsula.<br />

presented with different hatch colors. Each color represents a<br />

plant community as indicated in the subtitles of the Figures.<br />

The superposition of maps obtained can be un<strong>de</strong>rtaken<br />

through two different methods. By the differences between<br />

patch positions, patch areas and patch shapes revealed.<br />

On average the patch areas were bigger in the summer of<br />

2002/2003 than in the summer of 2009/2010, when the<br />

patch shapes show up totally different. But we can see that<br />

on average the patches of vegetation in 2010 appear in the<br />

same place as the patches of vegetation in 2003.<br />

The map obtained by overlaying of Hennequin Point was<br />

presented in the Figure 2. The contour of the PC patches,<br />

obtained in austral summer 2004/2005 year was presented<br />

with red lines. The PC patches, obtained in austral summer<br />

2010/2011 year are presented in a green hatch color.<br />

Figure 2, presents a superposition of maps ma<strong>de</strong> with the<br />

same methodology, but using different GPS receivers. The<br />

two maps were <strong>de</strong>signed with points obtained using the<br />

Stop and Go method which is able to obtain centimeter<br />

precision. We can see differences between the two maps.<br />

In the quadrant located at the longitu<strong>de</strong> 428.000, 429.000E<br />

and latitu<strong>de</strong>s 3.113.500, 3112.500N, there are 3 patches of<br />

PC 2005 which are not superposed with the PC 2011. In the<br />

same quadrant, they are almost 6 PC of 2011 which are not<br />

superposed with the PC 2005.<br />

Discussion<br />

The overlap of PC can indicate that both represent the<br />

same communities. The absence of patches in a map and<br />

a presence in another can indicate that the vegetation<br />

2003 was retracted from 2003 to 2010. This paradigm<br />

can be explained with the difference of obtaining the two<br />

maps. The construction of the contour of patches over a<br />

photographic image can generalize a big area like a plant<br />

community which can have other patches from another<br />

PC in it. To obtain the 2010 vegetation, it was necessary to<br />

make a survey walking around all the patches. Each patch<br />

had several points, which connected to form the shape. To<br />

do this walk is very important that the surveyor has the care<br />

to measure points at their limits between the vegetations and<br />

other themes. The limits are not sharply contoured and it<br />

is possible for there to be some limit confusion. There is a<br />

ten<strong>de</strong>ncy to translate the paradigm to encircle the patches.<br />

To solve this problem, it is necessary that the surveyor has<br />

training to i<strong>de</strong>ntify superficially which species is presented at<br />

each location of the study. The i<strong>de</strong>ntification of the transition<br />

between presence or absence of plants.<br />

Figure 2 can suggest that the 6 patches have grown over<br />

the last 6 years or the patches were covered with snow in<br />

2004/2005 austral summer, implying that they were not<br />

found by the surveyor. We have some patches superposed<br />

with the same shape. Due to the fact that they are not in the<br />

same position can be explained by a cartographic problem.<br />

The latter problem occurs frequently in other areas of the<br />

map.<br />

Conclusions<br />

Regarding the survey methods we need to study more and<br />

collect more <strong>da</strong>ta for further comparisons. We can use<br />

Satellite Images with high spatial resolution to compare<br />

places in temporal evaluation. Probably the methods<br />

using photography and satellite images georeferenced can<br />

generalize the patches. Surveys ma<strong>de</strong> from Stop and Go<br />

methods need more experience on the part of the surveyor<br />

and the limits between the schemes cannot be precisely<br />

<strong>de</strong>lineated. Differences of on average 2 or 3 meters can be<br />

consi<strong>de</strong>red insignificant. The GPS L1 or L1/L2 receivers<br />

show the highest precision to build the patches.<br />

Abstract : Elephant Island is located at 61° 07’ S and 55° 03’ W in the north of the South Shetland Islands. Stinker Point is<br />

the largest ice-free coastal area along Elephant Island, showing the highest level of richness of the island’s fauna and flora.<br />

The Antarctic biome is affected by its geographical isolation and special climatic conditions. The objective of this work is to <strong>de</strong>fine<br />

the most important species at Stinker Point, Elephant Island being the base in<strong>de</strong>x of ecological importance. The phytosociological<br />

study was conducted using the method of the quadrats. The sampling was done in the austral summer to 2012 in ice-free areas<br />

of Stinker Point. To obtain the importance of the species at the points of sampling the in<strong>de</strong>x of ecological significance (IES) was<br />

applied. Twenty-two different sites in the ice-free areas were sampled in this study and 70 species until now (including algae,<br />

liverworts, mosses, lichens, mushrooms and angiosperms) were i<strong>de</strong>ntified. Thirty-four species have an IES higher than 50, being<br />

Sanionia uncinata (Hedw.) Loeske the most important species.<br />

Key word: ecological significance, mosses, lichens, flowering plants<br />

Introduction<br />

The Antarctic continent is one of the harshest habitats in the<br />

world, especially for Antarctic flowering plants, lichens and<br />

bryophytes, which form the dominant elements in rocks and<br />

vegetation on the rocky ground (Kappen & Schroeter, 1997).<br />

The Antarctic vegetation is affected by the geographical<br />

isolation, climatic conditions and its <strong>de</strong>velopment is<br />

restricted to ice-free areas.<br />

Elephant Island is located at 61° 07’ S and 55° 03’ W in<br />

the north of the South Shetland Islands. It is a mountainous<br />

island covered with ice in its central area and in the austral<br />

summer parts of the coast are ice-free. Stinker Point is the<br />

largest coastal ice-free area of Elephant Island rich in fauna<br />

and flora (Pereira & Putzke, 1994). These authors inform that<br />

Stinker Point has two species of higher plants, Deschampsia<br />

antartica Desv. (Poaceae) and Colobanthus quitensis<br />

(Kunth.) Bart. (Caryophylaceae), 38 species of mosses, seven<br />

species of liverworths, 68 species of lichens and four species<br />

of macroscopic fungi.<br />

Lewis-Smith (2001) in a phytossociological survey found<br />

many species of mosses in association with the dominant<br />

species in the formation, reflecting the <strong>de</strong>pen<strong>de</strong>nce of these<br />

species of mosses on the dominant species, which should<br />

they become en<strong>da</strong>ngered, the <strong>de</strong>pen<strong>de</strong>nt species in turn<br />

would be en<strong>da</strong>ngered due to inter<strong>de</strong>pen<strong>de</strong>ncy.<br />

The bird colonies are <strong>de</strong>cisive in the distribution of<br />

plant species, as well as the climatic conditions and the soil.<br />

(Pereira & Putzke, 1994).<br />

The objective of this work was to <strong>de</strong>fine the most<br />

important species in Stinker Point, Elephant Island using<br />

the in<strong>de</strong>x of ecological significance.<br />

Materials and Methods<br />

Phytossociological study was conducted using the method<br />

of quadrats of Braun-Blanquet (1964), a<strong>da</strong>pted to Antarctic<br />

conditions (Kan<strong>da</strong>, 1986). The sampling was done in the<br />

2011/2012 austral summer in the ice-free areas of Stinker<br />

Point, Elephant Island, Antarctica.<br />

The species were i<strong>de</strong>ntified during the phytossociological<br />

survey. The plants not i<strong>de</strong>ntified in situ were collected and<br />

i<strong>de</strong>ntified in the laboratory analyzing the characters in<br />

the optical microscopy with help of the keys for species<br />

proposed by Putzke & Pereira (1990, 2001) and Ochyra et al.<br />

(2008) for bryophytes, Bednarek-Ochyra et al. (2000) for<br />

liverwort, Redon (1985) and Øvste<strong>da</strong>l & Lewis-Smith<br />

(2001) for lichens.<br />

To show the importance of the species in the points of<br />

sampling the in<strong>de</strong>x of ecological significance (IES) of Lara<br />

& Mazimpaka (1998) was applied, which combines the<br />

coverage and frequency (Victoria et al., 2009). This in<strong>de</strong>x has<br />

a value from 0-600, a value above 400 is very rare, because<br />

it would <strong>de</strong>note a consistent area almost absolute taxon<br />

in formation, but the value up to 50 showed a significant<br />

ecological importance (Victoria & Pereira, 2007).<br />

Results<br />

Twenty-two different formations in the ice-free areas<br />

were sampled in this study. 70 species were i<strong>de</strong>ntified<br />

(including algae, liverworts, mosses, lichens, mushroom and<br />

flowering plants). The species of macroscopic fungi, such<br />

as mushrooms cited in this study, have not been i<strong>de</strong>ntified<br />

to species level.<br />

In Table 1 the list of species with higher IES (>50) and<br />

the sampled point where they were found at Stinker Point<br />

is presented.<br />

Discussion<br />

Sanionia uncinata (Hedw.) Loeske showed IES ≥ 50 in<br />

13 to 18 points where that species were found. In 8 of these<br />

13 points S. uncinata was the most important species that<br />

had the highest IES value in the formation. In a single sample<br />

(point 20) this species reached a 573 value, in an in<strong>de</strong>x<br />

that ranged up to 600 as the maximum value. These results<br />

<strong>de</strong>monstrate S. uncinata as a dominant species in most of<br />

the formations in which it is occurs.<br />

Hennediella heimii (Hedw.) R.H Zan<strong>de</strong>r was the second<br />

most important specie found in the plant formation of<br />

Stinker Point, occurring in 16 of 22 sampled points. In seven<br />

points this species reached an IES ≥ 50 and in three of these<br />

points it showed itself to be the specie with the highest IES,<br />

reaching IES = 364 in a single point (point 19). Probably, the<br />

highest occurrence of this species in recent rocky terrains<br />

without a higher frequency of plant and lichen species, an<br />

increase of significant value.<br />

Chorisodontium aciphyllum (Hook. f. & Wilson) Broth.<br />

occurred in 11 of 22 sample points. In 8 points this species<br />

showed a IES above 50, with two of these points showing the<br />

highest IES values (297 in point 9 up to 497 in point 21). In<br />

spite of C. aciphyllum being less frequent in the ice-free areas<br />

of Stinker Point, when this species occurs it is important for<br />

the characterization of plant formation.<br />

For the lichens analyzed, two species showed an<br />

ecological importance. The IES were higher than 50 in five<br />

of the 22 sampling sites, when for Usnea antarctica Du Rietz<br />

the highest value at point 12 (IES = 253) was observed.<br />

Deschampsia antarctica Desv. showed an IES value<br />

higher than 50 in three of the five points sampled. For<br />

Colobanthus quitensis (Kunth) Bartl. an IES value higher<br />

than 50 was observed in three of six points sampled,<br />

although the higher values observed for the grass species<br />

that were not found as a dominant species in the samples.<br />

However, C. quitensis was observed as a dominant species<br />

in two sites when it occurred with an IES value up to 480<br />

in a single point (point 6).<br />

Conclusion<br />

Stinker Point has a wi<strong>de</strong>spread variety of plant species, being<br />

S. uncinata and H. heimmi the most distributed species<br />

among the sampled points. The higher IES of both species<br />

in the region can be attributed to a better a<strong>da</strong>ptation of<br />

these species to local environmental conditions. Further<br />

studies are being <strong>de</strong>veloped to better un<strong>de</strong>rstand the<br />

phytossociology of the plant communities in this region.<br />

Abstract: This study had the purpose of evaluating the effect of soil cover by vegetation on soil chemical attributes in a skua<br />

(Catharacta maccormicki) field at Punta Hennequin, Shetland Island, Antarctica. Four locals along a transect were sampled,<br />

involving soils with 5 and 100% of vegetal cover (L1 and L2, respectively) with Deschampsia+Colobanthus; bare alluvium soil<br />

(L3); and poor-drained moss (Sanionia uncinata) carpet with 100% soil cover (L4). Soil samples obtained from three layers and<br />

three replicates were submitted to chemical and physical analysis. Although both L1 and L2 are in the same nesting field, the more<br />

abun<strong>da</strong>nt vegetation at L2 promoted significantly larger (P < 0.05) total organic C (TOC) stocks in the soil than at L1 (43.08 and<br />

9.03 Mg C ha –1 , respectively, at the 0-40 cm layer). Total N stocks increased from 2.60 to 6.54 Mg ha –1 for L1 and L2, respectively.<br />

Although the presence of seabirds represents an important transfer of organic material from marine to the terrestrial environment,<br />

the differences evi<strong>de</strong>nce the importance of vegetation in or<strong>de</strong>r to raise the soil organic matter levels. Soil pH was consistently lower<br />

in L2 than L1 - about 1.0 unit for the soil layers herein evaluated, which is probably linked to the soil organic matter accumulation.<br />

Contrary to the distribution of TOC and TN contents, exchangeable P and K had no gradient along the soil profile, evi<strong>de</strong>ncing<br />

that most of the P and K is native from the parent material and their input by seabirds to the soil is negligible.<br />

Keywords: organic carbon, total nitrogen, seabird field<br />

Introduction<br />

Soil chemical and physical attributes affect and are affected<br />

by the type and abun<strong>da</strong>nce of vegetal plants growing in<br />

the locality in a dynamic interaction. In ice-free regions of<br />

maritime Antarctica, such interaction is usually influenced<br />

by the presence of seabird colonies and by the heterogeneity<br />

of soil parent material (Navas et al., 2008; Simas et al., 2008),<br />

resulting in complex systems that are not fully un<strong>de</strong>rstood<br />

(Ugolini & Bockheim, 2008; Vieira et al., 2012). For this<br />

reason, the purpose of the study was to evaluate the effect<br />

of soil cover by vegetation on the changes of soil chemical<br />

attributes in a skua field at Punta Hennequin, Shetland<br />

Island, Antarctica.<br />

Materials and Methods<br />

The study was performed in February 2011 in Punta<br />

Hennequin, Shetland Island, Antarctica (58° 23’ 21” W and<br />

62° 7’ 41” S). Four locations along a transect were sampled:<br />

L1 and L2 consisted of a skua (Catharacta maccormicki)<br />

field with 5 and 100% of vegetal cover, respectively, distant<br />

from each other about 50 m, in the same moraine (same<br />

level and parent material); vegetation was mainly composed<br />

by higher plant species, mostly of Deschampsia antarctica<br />

Desv. (Poaceae) and Colobanthus quitensis (Kunth) Bartl.<br />

(Caryophyllaceae); L3 was a poor-drained bare alluvium<br />

soil; and L4 was a poorly-drained moss (Sanionia uncinata)<br />

carpet with 100% soil cover, around a lake shore. Soil<br />

samples were obtained from three layers (0-10, 10-20 and<br />

20-40 cm <strong>de</strong>pth) at three replicates per locality, air-dried,<br />

ground and sieved (2 mm). Soil bulk <strong>de</strong>nsity samples were<br />

taken by the core method. Soil contents of sand, clay, silt,<br />

exchangeable P and K, total N and soil pH were <strong>de</strong>termined<br />

according to Te<strong>de</strong>sco et al. (1995). Total organic C (TOC)<br />

contents were <strong>de</strong>termined by dry combustion using a total<br />

organic C analyzer (Shimadzu TOC-VCSH, Shimadzu<br />

Corp., Kyoto, Japan). Chemical attributes were submitted<br />

to one-way ANOVA, with Tukey test (p < 0.05) to separate<br />

means in each soil layer. Physical attributes are reported<br />

with stan<strong>da</strong>rd <strong>de</strong>viations (n = 3).<br />

Results<br />

Clay contents were relatively similar among the soils of the<br />

four areas (Table 1). However, silt content was consistently<br />

greater for the soil in the moraine (L1 and L2) than for the<br />

other soils, which is likely due to the fact that the soil of<br />

the moraine is more autochthonous and stable than the<br />

others. Lower soil bulk <strong>de</strong>nsity was observed for L2 than for<br />

the other soils up to 20 cm soil layer, which is presumably<br />

credited to the plant roots effect on soil structure.<br />

Although both L1 and L2 are in a nesting/breeding<br />

field of skuas, the more abun<strong>da</strong>nt vegetation at the L2<br />

promoted soil TOC stocks about five times larger than<br />

L1 (9.03 and 43.08 Mg C ha –1 , respectively, at the 0-40 cm<br />

layer), achieving the largest contents in all soil layers herein<br />

evaluated (Figure 1a). Moss vegetation (L3) also promoted<br />

larger soil TOC contents, but this effect was restricted to the<br />

surface soil layer and was not significantly different from<br />

the others. Relatively similar behavior was observed for total<br />

nitrogen contents in the soil profile. Total N stocks increased<br />

from 2.60 to 6.54 Mg N ha –1 for L1 and L2, respectively<br />

(Figure 1b).<br />

The bare alluvium soil and the moss soil had larger<br />

exchangeable K and smaller P contents than L1 and L2<br />

(Figure 2). Contrarily to the distribution of TOC and TN<br />

contents, exchangeable P and K had no gradient along the<br />

soil profile. No significant effect of vegetation cover between<br />

L1 and L2 was observed for exchangeable P and K contents,<br />

but the soil pH was consistently lower in L2 than L1 - about<br />

1.0 unit for the soil layers herein evaluated, which is probably<br />

linked to the soil organic matter accumulation.<br />

Discussion<br />

Although the presence of the seabirds represents an<br />

important transfer of organic material from marine to the<br />

terrestrial environment, the differences in TOC and NT<br />

contents between L1 and L2 evi<strong>de</strong>nce the importance of<br />

the high soil cover by higher plant species in or<strong>de</strong>r to raise<br />

the soil organic matter levels. The seabirds are crucial to<br />

enrich the soil with N, which in turn favors the increase<br />

of vegetal cover and, in consequence, more birds are<br />

attracted, completing a feedback looping. However, if we<br />

consi<strong>de</strong>r that TOC stock in L1 is basically <strong>de</strong>rived from<br />

the presence of seabirds (as vegetation cover was low) and<br />

that the difference between L1 and L2 is primarily due to<br />

the occurrence of plants in the same field, we can infer<br />

that carbon accumulation in the soil was about 4.8 times<br />

larger in the “skuas+higher plants” condition than that of<br />

just skuas. In addition, we speculate that superior plant<br />

species have a larger potential to increase soil TOC and NT<br />

content not only due to their big biomass production rate<br />

(not evaluated), but also due to their important input of C<br />

and N in subsurface soil layers by their root system. This is<br />

supported by the greatest gradient of TOC contents in the<br />

soil profile un<strong>de</strong>r moss than un<strong>de</strong>r superior vegetal species,<br />

which is probably linked to the absence of root systems in<br />

the moss. However, such differences of TOC stocks between<br />

different vegetal species can be hid<strong>de</strong>n if only a surface soil<br />

layer is taken into account (Cannone et al., 2008).<br />

Despite the relatively low annual rates of C and N input<br />

at the vegetated skua fields, TOC and TN stocks in such<br />

soils can be as high as those found in non-polar regions<br />

(Vieira et al., 2009). Stocks of TOC of 40 Mg ha –1 are difficult<br />

to sustain in agricultural soils of tropical and subtropical<br />

climate because of their larger <strong>de</strong>composition rates<br />

(Vieira et al., 2009). Therefore, in a scenario of expansion in<br />

the vegetated area in maritime Antarctic soils, the potential<br />

of C sink through soil organic matter accumulation is<br />

relatively high.<br />

The prevalent absence of gradients for exchangeable P<br />

and K in the soil profile and the large differences among the<br />

soils strongly evi<strong>de</strong>nces that most of the P and K is mostly<br />

driven by their content in the parent material, while their<br />

input by seabirds to the soil is negligible. The only exception<br />

is the exchangeable P content in soil with moss, which is<br />

slightly smaller in the soil surface layer. In all soils, the<br />

exchangeable P and K contents are very high (CQFS, 2004)<br />

and are similar to those reported by Simas et al. (2008) for<br />

ornithogenic and weakly ornithogenic soils of the region.<br />

Conclusion<br />

In the localities of the present study, the presence of soil<br />

cover by higher plant species contributes markedly to<br />

increase the contents of total organic carbon and total<br />

nitrogen, being more effective than the cover by moss and<br />

much more effective than the presence of seabirds without<br />

vegetal cover. The contents of exchangeable P and K in such<br />

soils are more attributed to their content in the soil parent<br />

material than to the presence of seabirds and vegetation.<br />

Abstract: The aim of this work was to verify moss conservation status on ice-free areas of northern Maritime Antarctic, including<br />

<strong>da</strong>ta of Elephant Island, King George Island and Deception Island. The study started with the classification and <strong>de</strong>scription of<br />

the plant communities based primarily on phytosociological and biodiversity <strong>da</strong>ta. All records were obtained from 1991-1992 to<br />

2003-2004 austral summers. The coverage <strong>de</strong>gree and frequency of each species found was used to calculate the in<strong>de</strong>x of ecological<br />

significance. 22 most frequent species based on all island records were found. The most important species in both studied areas<br />

were Sanionia uncinata (Hedw.) Loeske, Polytrichastrum alpinum (Hedw.) G. L. Smith, Bartramia patens Brid., respectively,<br />

occurring in all the studied islands. These results <strong>de</strong>monstrate the fragility of plant communities in Maritime Antarctic, based on<br />

the low frequency and coverage of most species known to this area.<br />

Introduction<br />

Since 1940 there has been evi<strong>de</strong>nce through monitoring and<br />

observation of the global warming effect on the plant species<br />

of Maritime Antarctic, mainly related to the oscillations in<br />

the percentages of plant coverage (Lewis-Smith, 2001). An<br />

important tool to study these fluctuations in bryophytes<br />

populations was i<strong>de</strong>alized by Lara & Mazimpaka (1998).<br />

These authors <strong>de</strong>veloped the In<strong>de</strong>x of Ecological Significance<br />

(IES), which compares the frequency and abun<strong>da</strong>nce of <strong>da</strong>ta<br />

to <strong>de</strong>termine the importance of the species in a studied<br />

area. The in<strong>de</strong>x can be applied for moss conservation<br />

and phytosociological studies and for the classification<br />

of threatened species (Hallingbäck & Hodgetts, 2000),<br />

proposed by the International Union for Conservation of<br />

Nature (IUCN). Furthermore to reflect the importance of<br />

the particular species in plant formation, which also shows<br />

the <strong>de</strong>gree of association within species in the sample, such<br />

is the <strong>de</strong>gree of importance of maintaining this formation. If<br />

many species are associated with the dominant species of a<br />

formation, thus invariably they reflect the <strong>de</strong>pen<strong>de</strong>nce of the<br />

associated species, and if the dominant species is threatened,<br />

their <strong>de</strong>pen<strong>de</strong>nts also will be (Lewis-Smith, 2001).<br />

In or<strong>de</strong>r to complement the knowledge of plant<br />

communities in the ice-free areas of Admiralty Bay, are<br />

presented the conservation status of mosses based in<br />

several phytosociological studies <strong>de</strong>veloped in the Maritime<br />

Antarctic.<br />

Materials and Methods<br />

The <strong>da</strong>ta obtained in the phytosociological approaches since<br />

1991/1992 up to 2003/2004 austral summers, were compiled<br />

to verify the most frequent species found in the plant<br />

communities from northern Maritime Antarctic. Data was<br />

analyzed from some four islands from the South Shetland<br />

Islands, as follows: Elephant Island (1991/1992 summer);<br />

King George Island (2003/2004, 2004/2005 summers) and<br />

Deception Island (1993/1994). High coverage moss species<br />

or dominant lichen species were sampled using the usual<br />

collection methods. The i<strong>de</strong>ntification of the species was<br />

ased on specialized literature, such as Ochyra et al. (2008),<br />

Pereira & Putzke (1994) and Putzke & Pereira (2001). The<br />

in<strong>de</strong>x of ecological significance (IES) was calculated based<br />

on the Lara & Marzimpaka (1998), subsequently Victoria<br />

& Pereira (2007).<br />

Results<br />

Of the 102 moss species confirmed by Ochyra et al. (2008)<br />

for Antarctica, 22 of the most important moss species to<br />

northern Maritime Antarctic were found. From our <strong>da</strong>ta it<br />

was possible to verify the occurrence of Sanionia uncinata<br />

(Hedw.) Loske as the most frequent species in the three<br />

island communities is analyzed in (Tables 1 to 3). However<br />

with the IES of each species it was possible verify the other<br />

dominant species varieties of both islands (Figure 1).<br />

Polytrichastrum alpinum (Hedw.) G.L. Smith was observed<br />

as the second most important species in the ice-free areas<br />

of King George and Deception Islands.<br />

The IES also indicates the <strong>de</strong>gree of colonization of a<br />

<strong>de</strong>termined species in the sample (Lara & Mazimpaka, 1998)<br />

which can also suggest the effect of variations of species<br />

occurrences related to the available substrata. Thus, if a<br />

species <strong>de</strong>pends on a rich matter substrata and those are<br />

unavailable in that region that species will <strong>de</strong>cline due to<br />

the relevant substrata being missing (Victoria et al., 2006).<br />

Probably, for the regions where the terrains are composed<br />

of a lower fraction of organic matter only a few species<br />

inclu<strong>de</strong>d in the most important species list were found. This<br />

is the case of Deception Island, where, due the predominant<br />

volcanic substrata, only four species with significant in<strong>de</strong>x<br />

values (Table 3) were found, most plant communities being<br />

Figure 1. The most frequent moss found in northern Maritime Antarctic and their frequencies in each island sampled.<br />

restricted to the beaches (Putzke & Pereira, 2001) with a<br />

higher content of carbon and other nitrogen compounds.<br />

On the other hand at Elephant Island this relationship<br />

was not observed, for example, Stinker Point has higher<br />

nitrophilic soils related with the bird colonies (Pereira &<br />

Putzke, 1994) and the most important species of the list are<br />

also few. An explanation for the latter can be closely related<br />

to the effect of winds (Putzke & Pereira, 2001) such as in<br />

Admiralty Bay area, which is less exposed and thus shows<br />

a greater number of important species.<br />

Discussion<br />

Comparing the records obtained from the three islands,<br />

was observed such these corroborated with other initiatives.<br />

Most of the species are easily found in the area, but in<br />

lower coverage (IES > 50) with a lower number of species<br />

in higher abun<strong>da</strong>nce and coverage (Victoria et al., 2009,<br />

2011). Ochyra (1998) reports Sanionia uncinata (Hedw.)<br />

Loeske and Polytrichastrum alpinum (Hedw.) G.L.Smith<br />

as the most abun<strong>da</strong>nt moss species in Maritime Antarctic,<br />

being in lower risk of threat compared with other moss<br />

species in this area. These results can suggest the sensibility<br />

of these plant communities to environmental changes, since<br />

the species were found in small patches and populations,<br />

and it showed lower resistance and resilience, wherever<br />

the interrelationships within the organisms was low<br />

(Schaefer et al., 2004). Any impacts on these species can be<br />

irreversible (Victoria & Pereira, 2007).<br />

For example, we can cite the most frequent Bryaceae<br />

occurrences found. Ptychostumum pseudotriquetrum (Hedw.)<br />

J.R. Spence & H.P. Ramsay and Bryum orbiculatifolium<br />

Card. et Broth. Depend on ice-melt found in the water<br />

lines of austral summer (Allison & Lewis-Smith, 1973;<br />

Kan<strong>da</strong>, 1986). P. pseudotrichetrum has higher abun<strong>da</strong>nce<br />

in our samples from King George Island and can be<br />

consi<strong>de</strong>red a lower <strong>de</strong>gree of threatened species compared<br />

to B. orbiculatifolium. The size of P. pseudotrichetrum<br />

population provi<strong>de</strong>s best response in the case of fast<br />

environmental changes, perhaps an a<strong>da</strong>ptative success<br />

related of a higher coverage <strong>de</strong>gree (Lewis-Smith, 2001).<br />

Victoria et al. (2011) records for small sites of Admiralty<br />

Bay area, both in the King George Island (Ulmann Point and<br />

Coman<strong>da</strong>nte Ferraz beach) similar results to those found for<br />

the whole South Shetlands archipelago, whereby S. uncinata<br />

also occurs in higher frequency and coverage. However<br />

with less frequency for P. alpinum P. pseudotrichetrum, for<br />

64 | Annual Activity Report 2011


Ferraz beach, and Syntrichia magellanica (De Not.) Mitt, for<br />

Ulmann Point the species are the second most important<br />

for each area, perhaps because of the lower complexity of<br />

these two plant communities sampled, these communities<br />

being composed mainly of emergent species, such as these<br />

two species mentioned (Victoria et al., 2009).<br />

Victoria & Pereira (2007) reported the same condition<br />

for Arctowski region and Hennequin Point, both regions<br />

located in Admiralty Bay area. The other frequent moss<br />

species mentioned were found to be important species<br />

for the plant communities at Hennequin Point and in<br />

Arctowski region (Victoria & Pereira, 2007), except for<br />

Hennediela heimii (Hedw.) Zand, which was found in higher<br />

frequency in Ferraz beach in the present study compared<br />

with other areas.<br />

All moss species, as well the land biota found in<br />

Admiralty Bay, were directly and indirectly affected by<br />

human presence. The maintenance of scientists and military<br />

insi<strong>de</strong> and outsi<strong>de</strong> of research stations, shelters and camps,<br />

involves high consumption of fossil combustibles and<br />

creates high residue production, causing unclear impacts<br />

on Antarctica wildlife (Olech, 1996).<br />

Conclusion<br />

This essay <strong>de</strong>monstrates the fragility of moss formation<br />

in the ice-free areas of northern Maritime Antarctic,<br />

such species of Bryum, Pohlia and Andreaea appear as<br />

the mostly threatened species. A <strong>de</strong>scriptive <strong>da</strong>ta bank<br />

can collaborate for the continued monitoring of plant<br />

communities, contributing to the conservation of plant<br />

species in Admiralty Bay area. The phytosociological studies<br />

can contribute to the management of scientific activities<br />

involved with the Brazilian Antarctic Program.<br />

Abstract: The aim of this work was to report on the lichen-moss association in the ice-free areas of Elephant Island, King George<br />

Island, Nelson Island and Deception Island. The study started with the classification and <strong>de</strong>scription of the plant communities based<br />

primarily on phytosociological and biodiversity <strong>da</strong>ta. All <strong>da</strong>ta were obtained from 2003-2004 to 2011-2012 austral summers. 12<br />

most frequent lichen-moss association species based on all island records were found. The most frequent association in both studied<br />

areas involved foliose-crustose lichen with a moss carpet species, such as Psoroma cinnamomeum Malme with Sanionia uncinata<br />

(Hedw.) Loesk. The occurrences for each island as well as the common association found in all sampled islands are <strong>de</strong>monstrated.<br />

Keywords: lichen ecology, bryophytes, South Shetlands archipelago, Maritime Antarctic<br />

Introduction<br />

The composition, abun<strong>da</strong>nce and distribution of the plant<br />

communities in Antarctica is directly related with the<br />

changes in the climatic conditions and the effects of climate<br />

warming, resulting in alterations including changes in<br />

populations (Frenot et al., 2005; Convey, 2006).<br />

Lichens is the group that has the highest species diversity,<br />

meeting the conditions best a<strong>da</strong>pted in Antarctica, having<br />

an important contribution in floristic composition in these<br />

areas, and their existence is <strong>de</strong>pen<strong>de</strong>nt on ice-free regions,<br />

climate and a stable substrate (Redon, 1985; Kappen &<br />

Schroeter, 1997). Lewis-Smith (2001) in a phytosociological<br />

study found that many species of mosses are associated<br />

with dominant species in the formation, reflecting the<br />

<strong>de</strong>pen<strong>de</strong>nce of these species of mosses because if the<br />

dominant species become en<strong>da</strong>ngered, the <strong>de</strong>pen<strong>de</strong>nt one<br />

will become en<strong>da</strong>ngered too.<br />

Studies on the coexistence of terrestrial algae species and<br />

lichenized fungi were also published, such their relationship<br />

within the growth habit and ecological a<strong>da</strong>ptation in the<br />

Antarctic environment. Associations are reported between<br />

mosses and lichens species, and plant formations growing<br />

in associations at King George Islands, Nelson Island and<br />

Elephant Island (Allison & Lewis-Smith, 1973; Pereira &<br />

Putzke, 1994; Victoria et al., 2006). A mapping of these plant<br />

formations is being conducted to infer the environmental<br />

changes as well the human impact over the years of the plant<br />

composition in the Antarctic ice-free areas.<br />

In or<strong>de</strong>r to complement the knowledge of plant<br />

communities in the ice-free areas of Maritime Antarctic,<br />

associations between lichens and mosses observed during<br />

the phytosociological survey ma<strong>de</strong> since 2003-2004 up to<br />

2011-2012 austral summers are presented here, as well as<br />

the strongest associations found in each surveyed island<br />

together with their coverage and frequencies.<br />

Materials and Methods<br />

Using the phytosociological <strong>da</strong>ta obtained since 2003/2004<br />

up to 2011/2012 austral summers all records from lichens<br />

found associated to moss species were analyzed. The<br />

<strong>da</strong>ta was obtained from a survey using Braun-Blanquet<br />

phytosociological methods (Braun-Blanquet, 1964), a<strong>da</strong>pted<br />

to Antarctic conditions (Kan<strong>da</strong>, 1986). Whenever possible,<br />

samples of lichens with highly <strong>de</strong>veloped ascomas (presence<br />

of apothecia or perithecia) were ma<strong>de</strong>. Saxicolous species<br />

were pulled out with the help of a geologist hammer, and<br />

muscicolous and/or terricolous species, with the help of a<br />

knife, to make sure the samples would come out with some<br />

substrate. I<strong>de</strong>ntification of the species was based on the work<br />

of Redon (1985), Ochyra (1998), Pereira & Putzke (1994)<br />

and Putzke & Pereira (1990). The records were or<strong>de</strong>red in<br />

a frequency range, by the most to the less frequent species<br />

found in association.<br />

Results<br />

Based on the phytosociological <strong>da</strong>ta it was possible to<br />

verify the occurrence of 12 of the most frequent lichenmoss<br />

associations in ice-free areas in Maritime Antarctic<br />

(Figure 1). Only three associations were observed in all<br />

the sampled islands, being represented by thalose-foliose<br />

lichens. The lichen Psoroma cinamomeum Malme was<br />

found as being the most frequent lichen found associated<br />

with mosses, mainly with species where the cushion is the<br />

most frequent life form. Leptogium spp. were also found<br />

frequently associated with moss species, but the opposite to<br />

that was observed for the previous association, these lichens<br />

were found commonly associated with moss carpets such<br />

Sanionia uncinata (Hedw.) Loeske.<br />

When comparing the records of all the islands a lower<br />

occurrence of fruticose lichens associated with mosses<br />

is observed, probably due to this lichen life form being<br />

found often in rocky sites where both lichen and moss<br />

species are well a<strong>da</strong>pted to colonize rock outcrops directly<br />

(Victoria et al., 2006). Cushion mosses occur mainly in<br />

rocky terrains in higher places (more than 100mts), often<br />

without the need for an early-colonized substrata, growing<br />

directly on outcrops (Ochyra, 1998). This moss life form can<br />

spread to uncovered lower terrains and then are immediately<br />

available for the muscicolous lichen colonization, such as<br />

Ochrolechia frigi<strong>da</strong> (Sw.) Lynge. This lichen species was<br />

found in several sites in association with Andreaea spp.<br />

(Figure 2a) in the sampled islands, except for Deception<br />

Island, frequently found in beach plateaus. This association<br />

is one of the most frequent in Nelson Island along with<br />

Usnea antarctica-Cladonia spp. - Polytrichum juniperinum<br />

and Huea coralligera - Sphaeorophorus globosus - Usnea<br />

aurantiacoatra - Syntrichia saxicola association (Figure 2b<br />

and 2c, respectively).<br />

The same association was the most frequently found<br />

in Elephant Island (Pereira & Putzke, 1994; Putzke &<br />

Pereira, 2012). Two associations were found only in a single<br />

island, one composed by a fruticose lichen (Usnea spp.-<br />

Polytrichastrum alpinum) and the other by a dimorphic<br />

lichen (Cladonia metacorallifera – Sanionia uncinata,<br />

Figure 2d) both in lower frequencies in the King George<br />

Island. The association between Psoroma cinnamomeum<br />

J.R. Spence & H.P. Ramsay were the most frequent<br />

association observed in the Admiralty Bay area (King<br />

George Island). Dimorphic lichen was also found associated<br />

with other fruticose lichens, often in higher plateau<br />

(Øvste<strong>da</strong>l & Lewis-Smith, 2001; Victoria et al., 2009), the<br />

latter being found in Elephant, Nelson and King George<br />

Islands in the Cladonia metacorallifera-Sphaeorophorus<br />

globosus-Polyrtrichastrum alpinum association (Figure 2f).<br />

Discussion<br />

The plants and lichen species found in Antarctica were<br />

<strong>de</strong>veloping, mainly, on rocks or moist soils, the rocks<br />

being fragmented since the soil had a higher ornithogenic<br />

influence. Thus the lichen and moss association were often<br />

found in terrain types where both organisms are a<strong>da</strong>pted,<br />

corroborating the reports ma<strong>de</strong> from several studies on<br />

plant communities in Antarctica (Gimingham & Lewis-<br />

Smith, 1970; Putzke & Pereira, 1990; Victoria et al., 2006,<br />

2009). Several studies reported lichen and mosses growing<br />

at relatively successful growth rates in Polar Regions when<br />

compared with other environments (Scott, 1990).<br />

These findings can be related with the human impacts<br />

in the area, to <strong>de</strong>creasing diversity along the two summer<br />

seasons (Victoria & Pereira, 2007). For Sancho et al. (2007)<br />

these changes can be a climate change indicator, because that<br />

lichen species found in the studied region are susceptible<br />

to extreme temperature variation, increasing or <strong>de</strong>creasing<br />

their growth (Sancho et al., 2007), but the fast <strong>de</strong>velopment<br />

and <strong>de</strong>ath of the foliose muscicolous lichen cannot be<br />

discar<strong>de</strong>d, as certain types of foliose lichens are among the<br />

fastest-growing species which have the ability to grow up<br />

to one centimeter per year, and this growth rate is unusual<br />

in most lichen species (Bednarik, 2004).<br />

Conclusion<br />

The lichen moss association observed in all plant<br />

communities distributed in the South Shetlands Islands<br />

can be used as a indicator of plant sucession on the ice-free<br />

areas. Further monitoring studies are nee<strong>de</strong>d to clarify<br />

these diversity changes in plant associations in the Maritime<br />

Antarctic.<br />

Abstract: Fungi are the most important nutrient cycling organisms in any ecosystem, which is also the case in Antarctica. Among<br />

the species, the Agaricales (Basidiomycota), popularly known as mushroom has a reported presence in this continent, but with no<br />

monographic account done up to now. In field trips to Antarctica and especially to the South Shetland Archipelago, we collected<br />

specimens during a period of 25 years of study of this or<strong>de</strong>r and reviewed specimens from other collections to present a systematic<br />

account of the or<strong>de</strong>r. The collecting and studying of samples was done according to the usual methods in Agaricales mo<strong>de</strong>rn<br />

taxonomy and the material was <strong>de</strong>posited in the HCB herbarium. The study of collections permits the recognition of 9 species<br />

of Agaricales from the area. Leptoglossum lobatum, L. omnivorum and Simocybe antarctica were collected for the first time in<br />

Elephant Island, Antarctica. Species are illustrated and a dichotomous key is proposed for the easy i<strong>de</strong>ntification.<br />

Keywords: Antarctica, fungi, taxonomy<br />

Introduction<br />

The South Shetland Archipelago is a group of 11 greater<br />

islands located at the Northern area of the Antarctic<br />

Peninsula, at ca. 800 km South of South America in an area<br />

called the Maritime Antarctic.<br />

The Maritime Antarctic vegetation is basically composed<br />

of cryptogams (Bryophyta, Marchantiophyta, Lichens and<br />

Algae) and two species of flowering plants (Longton, 1985).<br />

Fungi are also very well represented, but only recently the<br />

group has been monographed (Onofre et al., 2007), but<br />

with no mention of the macroscopic mushrooms of the<br />

Agaricales or<strong>de</strong>r.<br />

The first revision on Antarctic fungi that inclu<strong>de</strong>d<br />

Agaricales was that of Pegler et al. (1980) who reported only<br />

two species in the South Shetland but with references to 13<br />

species in Sub-Antarctic areas.<br />

Gumińska et al. (1994) refers to the occurrence of<br />

4 species (Galerina pseudomycenopsis, Arrhenia salina,<br />

Omphlaina antarctica and Omphalina pyxi<strong>da</strong>ta) collected<br />

in the South Shetland but only sampled in Livingstone and<br />

King George Island.<br />

This work <strong>de</strong>als with the species of Agaricales collected<br />

over 25 years of research activities in the South Shetland<br />

Islands and aims to monograph the or<strong>de</strong>r in the area.<br />

Materials and Methods<br />

The work was done on the South Shetland Archipelago,<br />

mainly in Elephant, Penguin, King George, Nelson and<br />

Deception Islands, Antarctica. The moss carpets were<br />

studied for the occurrence of ring forming fungi. The carpets<br />

chosen were entirely photographed, the photos mounted to<br />

create a map, drawing all the ring fungi found in its exact<br />

point of occurrence. The map was used to un<strong>de</strong>rstand the<br />

fungi distribution.<br />

Collections of mosses were taken to laboratory for<br />

i<strong>de</strong>ntification and or maintenance in culture (humid<br />

chamber) for evaluation.<br />

Results<br />

Nine species of Agaricales were found in the South Shetland<br />

Islands (plus one introduced), keyed out and listed below<br />

(Figure 1). There were found two species with smooth<br />

hymenophore and one with vein like gills, probably<br />

indicating an a<strong>da</strong>ptation to cold environments. There were<br />

found more white spored agarics (6) than brown spored<br />

ones (4). Galerina perrara Sing. appears to be specific<br />

to Chorisodontium acyphyllum, being all the other nonsubstrate<br />

specific. Sanionia uncinata is the substrate most<br />

used among the moss species.<br />

it was probably introduced.<br />

Discussion and Conclusion<br />

Ten species of mushrooms are found in the South Shetland<br />

Islands - Antarctica, only one not collected (Pholiota<br />

spumosa), since it was originally found on introduced<br />

wood. Simocybe antarctica was grown in laboratory when<br />

reported to Antarctica and is here registered fruiting for<br />

the first time in the area. All the remaining species were<br />

found also in other areas on the Archipelago indicating<br />

a more wi<strong>de</strong>spread distribution in the area. More studies<br />

are nee<strong>de</strong>d as to i<strong>de</strong>ntify new occurrences to the area and<br />

substrate preferences of the registered species, including<br />

<strong>de</strong>scription of its relationship with the substrate.<br />

Abstract: The comprehension of species responses to climate change is one of our present ecological challenges. This paper aims<br />

to evaluate the <strong>de</strong>mographic responses of a Southern Giant Petrel population according to climate factors. We used a Multi-State<br />

Mark-Recapture method to estimate survival from bree<strong>de</strong>r and non-bree<strong>de</strong>r, and transition rates. Bree<strong>de</strong>r survival response to<br />

Southern Oscillation In<strong>de</strong>x, Antarctic Oscillation In<strong>de</strong>x and temperature. Non bree<strong>de</strong>r survival response to Southern Oscillation<br />

In<strong>de</strong>x and temperature and Desertion rate with response to Temperature only in summer. Southern Giant Petrels are associated<br />

with warmer sea conditions. No recent <strong>de</strong>crease caused by climate factors can be expected un<strong>de</strong>r the scenario of warming in<br />

Antarctic Peninsula, and actual population size makes this assumption reasonable.<br />

Keywords: Antarctic oscillation, <strong>de</strong>mography, El Niño Southern oscillation<br />

Introduction<br />

The annual variations of the El Niño Southern Oscillation<br />

are influential over the Antarctic Circumpolar Current<br />

(ACC). Anomalies on the ACC are directly correlated with<br />

atypical variations in the seasonal cycles of sea ice caps,<br />

disrupting trends on ocean and atmospheric temperature<br />

in Antarctica by affecting the Antarctic Oscillations (Gong<br />

& Wang, 1999; Kwok & Comiso, 2002).<br />

Seabirds that breed at higher latitu<strong>de</strong>s are affected by<br />

these climate variations through a disruption in <strong>de</strong>mography<br />

rates (Warren et al., 2009), population size (Ainley et al.,<br />

2005) and increased area of dispersion to the north of<br />

Juvenile after fledging (San<strong>de</strong>r et al., 2010). The present<br />

paper evaluates the <strong>de</strong>mographic response of an Antarctic<br />

Southern Giant Petrel (SGP) population to the Southern<br />

Oscillation In<strong>de</strong>x (SOI), Antarctic Oscillation In<strong>de</strong>x (AOI)<br />

and temperature in the 80s. The <strong>de</strong>mography responses of<br />

Antarctic seabirds to climate are unknown for most species.<br />

Therefore the present paper contributes to the knowledge<br />

about the influence of climate un<strong>de</strong>r the Antarctic biota.<br />

Materials and Methods<br />

The study was conducted at Elephant Island, South<br />

Shetlands, precisely at Stinker Point (61° 07’ 31’’S and<br />

55° 19’ 26’’ W). Adult Southern Giant Petrels (Macronectes<br />

giganteus) were ban<strong>de</strong>d and recovered from 1986/1987<br />

until 1993/1994 with aluminum bands supplied by the<br />

National Center for Conservation of Wild Birds (CEMAVE,<br />

Portuguese acronym). For evaluation of survival rates of<br />

bree<strong>de</strong>r and non-bree<strong>de</strong>r stages we used a Multi-State Mark-<br />

Recapture Mo<strong>de</strong>l using the <strong>da</strong>ta collected between 1986<br />

and 1992. Breeding seasons: 1986-87, 1987-88, 1988-1989,<br />

1989-90; 1990-91, 1991‐92. The stages bree<strong>de</strong>r and non<br />

bree<strong>de</strong>r were used for the analysis. We evaluated whether the<br />

responses of survival, recapture and transition probabilities<br />

were constants or time <strong>de</strong>pen<strong>de</strong>nts through a multi-mo<strong>de</strong>l<br />

inference with AICc classification of best mo<strong>de</strong>ls using the<br />

Mark ® software. We used the rates from the 64 resulting<br />

mo<strong>de</strong>ls in a forward analysis. Demography responses<br />

to climate were tested through Analysis of Covariance<br />

ANCOVA by PASW 18.0, with α = 95%.<br />

Results<br />

The average SOI presented a greater variation along the years<br />

than the AOI, while SOI ten<strong>de</strong>d to be lower in summer in the<br />

last three years of the study (Figure 1). Average temperature<br />

ten<strong>de</strong>d to remain positive in summer (but got close to 0 °C<br />

in the last two years) and negative in winter, with a peak in<br />

the 1989 winter, when it reached –1 °C (Figure 2).<br />

Bree<strong>de</strong>r survival (BS) and non bree<strong>de</strong>r survival (NBS)<br />

ten<strong>de</strong>d to show <strong>de</strong>cline throughout all the years, while<br />

<strong>de</strong>sertion rate (DR) showed an increasing trend. Return rate<br />

(RR) was constant along the years (Figure 3). BS answered<br />

to SOI in winter and summer, AOI in summer and to<br />

temperature in winter. The greater slope was positive: AOI<br />

in summer. NBS answered only to SOI and temperature in<br />

winter, with a greater slope in winter SOI, but both values<br />

very closed. DR was only related to temperature in summer<br />

(negative slope) and RR was not related to any climate<br />

variable (Table 1, Figure 3).<br />

Discussion<br />

Adults are less responsive to environmental variability<br />

nonetheless minimal variations on the survival causes<br />

pronounced <strong>de</strong>creases on the population growth rate<br />

(Barbraud et al., 2010). The stan<strong>da</strong>rd trend in Stinker<br />

Point seems to be: higher temperatures in both summer<br />

and winter enhance survival and reduce <strong>de</strong>sertion from<br />

breeding. Higher SOI and AOI mean higher temperatures<br />

in Antarctica (Gong & Wang, 1999; Kwok & Comiso, 2002).<br />

For bree<strong>de</strong>rs, the summer component must be the most<br />

important, since during breeding the energy expenditure to<br />

raise a chick overlaps with energy spent on survival. Other<br />

sub-Antarctic and temperate-water seabird’s adult survival<br />

are affected by temperature and SOI (Croxall et al., 2002;<br />

Rolland et al., 2010). As a consequence of the actual trend<br />

for Antarctic Peninsula region of warming, one can expect<br />

this population may not suffer <strong>de</strong>clines caused by climate<br />

change. Such enhances can be consi<strong>de</strong>red probable, since<br />

the actual population numbers are greater than those from<br />

the studied years.<br />

Conclusion<br />

SGPs from Stinker Point are associated with warmer sea<br />

conditions. Their survival is probably enhanced by the<br />

current scenario of warming in the Antarctic Peninsula,<br />

as consequence no impending <strong>de</strong>crease caused by climate<br />

factors can be expected.<br />

Abstract: The influences of El-Niño over seabird populations have been <strong>de</strong>monstrated for a great number of species, including<br />

Antarctic species. We evaluated the effects of Southern Oscillation In<strong>de</strong>x (an atmospheric component of El-Niño) over a breeding<br />

population of Kelp Gulls in Admiralty Bay, King George Island. We counted breeding pairs in all ice-free areas in the 2009/10 and<br />

2010/11 summers, and used past values of the same areas from literature. We found the lower numbers of kelp gull pairs occur<br />

at the extreme values of Southern Oscillation In<strong>de</strong>x, the lower and the higher. This is strong evi<strong>de</strong>nce of the El-Niño influences<br />

on population processes within Admiralty Bay kelp gulls, probably by affecting the <strong>de</strong>cision on breeding or skipping breeding in a<br />

given year. Such a situation can affect the population in the long term by reducing their instantaneous breeding success.<br />

Keywords: climatic changes, El-Niño Southern Oscillation, King George Island<br />

Introduction<br />

Climate is the main force driving high-latitu<strong>de</strong> bird<br />

populations (Mallory et al., 2009; Croxall et al., 2002).<br />

Climate variations can eventually induce breeding adults<br />

to abandon their nests or chicks (comprising the main<br />

cause of <strong>de</strong>crease in reproductive success) (Mallory et al.,<br />

2009), and affect populations in the long term by reducing<br />

adult survival (Rolland et al., 2010) and recruitment rates<br />

(Ainley et al., 2005). Egg laying, and size of breeding<br />

population can also shift year by year as a response to climate<br />

constraints (Croxall et al., 2002; Barbraud & Weimerskirch,<br />

2006). The Variations of the El-Niño Southern Oscillations<br />

are influential over the Antarctic Climatic Oscillations<br />

and temperature (Changzheng & Feng, 2010). Studies<br />

<strong>de</strong>monstrated that the temperatures are not the only<br />

important predictor of seabird responses to climate, but also<br />

climatic in<strong>de</strong>xes (Rolland et al., 2010). Thus, our objective<br />

is to evaluate whether a breeding population of Kelp Gull<br />

respond to El-Niño Southern Oscillation In<strong>de</strong>x (SOI).<br />

Materials and Methods<br />

All the ice-free areas of Admiralty Bay, King George Island<br />

(Antarctica) were sampled, excluding the areas near the<br />

American Station Copacabana, but including the southern<br />

areas of SSSI8 (Figure 1). Censuses were conducted during<br />

the 2009/2010 austral summer between November 2009<br />

and March 2010. All breeding pairs were counted, taking<br />

in account the active nests, or those that had eggs laid in<br />

them. The nests were also mapped with GPS receptors. The<br />

ice-free areas were classified in accor<strong>da</strong>nce with San<strong>de</strong>r et al.<br />

(2006). The abun<strong>da</strong>nce of breeding pairs in past years was<br />

used (Jablonski, 1986; San<strong>de</strong>r et al., 2006) to <strong>de</strong>tect time<br />

variation as a response to weather. We get the Southern<br />

Oscillation In<strong>de</strong>x (SOI – the atmospheric component of El-<br />

Niño) <strong>da</strong>ta bank from NOAA (www.noaa.gov). To analyze<br />

the response of Kelp Gull pairs to SOI we applied an Analysis<br />

of Covariance using a negative binomial distribution mo<strong>de</strong>l<br />

as the number of pairs has a similar distribution using the<br />

SPSS 18.0 (α = 95%).<br />

Results<br />

The number of breeding pairs in all Admiralty Bay was 20<br />

and 24 in 2009/10 and 2010/11 summers, respectively. Five<br />

areas presented Kelp Gull reproduction in 2009/10 (A,B,G,O<br />

and V) and nine areas in 2010/11, from which five were the<br />

same from the last summer plus H,Q and R (Figure 1). By<br />

a simple visual comparison with past <strong>da</strong>ta (Jablonski, 1986;<br />

San<strong>de</strong>r et al., 2006) we clearly see an abrupt reduction of<br />

number of pairs of Kelp Gulls in Admiralty bay between<br />

2004/05 and 2009/2010, which is followed by an increase<br />

in the subsequent year, the referred reduction seems to be<br />

related to the variation of SOI (Figure 2).<br />

In fact, the number of pairs can be explained by the<br />

variation of SOI (Wald-χ 2 = 3.7; B = –0.31; P = 0.05). The<br />

lower average number of pairs occurred at the extreme<br />

values of SOI (Figure 2) in the extreme negative and in<br />

the extreme positive, in both years we sampled (2009/10<br />

and 2010/11) (Figure 3). The Higher SOI the warmer the<br />

temperature (Figure 4), so, extremes of SOI tends to cause<br />

reduction in the reproductive population of Kelp Gulls.<br />

Discussion<br />

One of the consequences of global climate changes is the<br />

increase in frequency of cold or warm anomalies. The fauna,<br />

particularly the top pre<strong>da</strong>tors, is simultaneously affected<br />

in its breeding and survival by the increased sea ice-cap<br />

(Croxall et al., 2002) and variations on the availability and<br />

accessibility of food during the breeding period and winter<br />

The variations of El-Niño have an influence on Antarctic<br />

waters and can affect the animal population and ecological<br />

processes within populations. In the short term such effect<br />

reduces the numbers of breeding pairs and as a consequence<br />

the breeding success of the population. In the long term,<br />

recruitment rates can be affected, and it may imply in lower<br />

growth rates.<br />

(Lescroël et al., 2009; Beaulieu et al., 2010). One explanation<br />

for such changes is the increasing influence of ENSO in<br />

Antarctica (Croxall et al., 2002). The 2009/10 summer was<br />

the col<strong>de</strong>st in the last <strong>de</strong>ca<strong>de</strong>s (INPE, 2010). We verified<br />

in surveys that there were few ice-free areas, reducing<br />

the availability or suitability of breeding habitat, but the<br />

subsequent summer (2010/11) was warmer providing a<br />

Abstract: Reproductive population size of both the Gentoo penguin (Pygoscelis papua) and Chinstrap penguin (Pygoscelis<br />

antarctica) has changed over the last <strong>de</strong>ca<strong>de</strong>s in many sites in the South Shetlands Islands. We evaluated the population sizes of<br />

these species on Stinker Point, Elephant Island, South Shetlands, Antarctic, during the breeding season 2009, 2010 and 2011, and<br />

we compared with preterit studies. Over the last 40 years, the number of breeding pairs here have shown fluctuations, with changes<br />

of up to 32%. It is possible that these fluctuations are related to the variation in prey availability and/or climate change. However,<br />

additional census and <strong>de</strong>mographic surveys in Elephant Island are clearly nee<strong>de</strong>d to <strong>de</strong>termine whether the <strong>de</strong>cline represents a<br />

long-term trend or random circumstantial fluctuations.<br />

Introduction<br />

Penguins comprise 90% of the total Antarctic avian biomass<br />

(Croxall et al., 2002). Only King penguin (Aptenodytes<br />

patagonicus), Macaroni penguin (Eudyptes chrysolophus),<br />

Rockhopper penguin (E. chrysocome), A<strong>de</strong>lie penguin<br />

(Pygoscelis a<strong>de</strong>liae), Gentoo penguin (P. papua) and<br />

Chinstrap penguin (P. antarctica) breed on ice-free areas<br />

of the Antarctic Peninsula coast and sub-Antarctic Islands<br />

(Woehler, 1993). Of the five penguin species occurring on<br />

Elephant Island the Gentoo and Chinstrap penguin are<br />

the most abun<strong>da</strong>nt. The Gentoo penguin is circumpolar<br />

in breeding and the largest colonies are found in the<br />

Falklands, South Georgia and Kerguelen Islands. Smaller<br />

populations can be found in Macquarie Island, Heard Island,<br />

McDonald Islands, South Shetland Islands and Antarctic<br />

Peninsula (Peterson, 1979). The Gentoo penguin is the<br />

least abun<strong>da</strong>nt of the Antarctic breeding penguin species,<br />

with 314.000-520.000 breeding pairs, and has suffered a<br />

major <strong>de</strong>cline over the last two <strong>de</strong>ca<strong>de</strong>s (BirdLife, 2009).<br />

Chinstrap penguin populations, ≈7.4 million breeding<br />

pairs, are found breeding mainly in sub-Antarctic Islands<br />

and along the Antarctic Peninsula (Woehler, 1993). The<br />

number of breeding pairs has shown fluctuations in the last<br />

50 years, due to climate changes, Antarctic krill (Euphausia<br />

superba) availability, variation in total area of ice-free sites<br />

suitable for breeding and increase in tourism and fishing<br />

activities (Conroy et al., 1975; Jablònski, 1984; Woehler<br />

& Croxall, 1997; Croxall et al., 2002; Hinke et al., 2007;<br />

Trivelpiece et al., 2011).<br />

On Elephant Island, South Shetlands, Gentoo and<br />

Chinstrap penguins co-exist and breed in large colonies<br />

near each other (Petry, 1994). We compare the breeding<br />

population size over the last 40 years of Gentoo and<br />

Chinstrap penguins on Stinker Point, Elephant Island,<br />

and we calculated the population growth rates during this<br />

period.<br />

Materials and Methods<br />

Three observers conducted a direct counting of nests of<br />

Gentoo and Chinstrap penguins, to estimate the numbers of<br />

breeding pairs on Stinker Point (61° 07’ 31” S; 55° 19’ 26” W),<br />

Elephant Island, South Shetlands Archipelago. The total<br />

population was <strong>de</strong>termined for each site by averaging all<br />

total counts that differed less than 10% according to the<br />

stan<strong>da</strong>rd CCAMLR (The Commission for the Conservation<br />

of Antarctic Marine Living Resources) Ecosystem<br />

Monitoring Program Methods (CCAMLR, 2004).<br />

Average annual growth rate was calculated using<br />

the Yáñez In<strong>de</strong>x, i (Yañez et al., 1984), following:<br />

i = [(BPpr/BPps) 1/n – 1] × 100, BPpr stands for the number<br />

of breeding pairs at present, BPps stands for the number of<br />

breeding pairs in former surveys and n stands for the years<br />

that passed by. The average population growth rate was<br />

calculated and compared with <strong>da</strong>ta collected in 2009, 2010<br />

and 2011, <strong>da</strong>ta from past studies such 1970 (Furse & Bruce,<br />

1972) and 1985, 1986, 1987, 1988, 1990, 1991 (Petry, 1994).<br />

Results<br />

In the last 40 years the numbers of breeding pairs of Gentoo<br />

and Chinstrap penguins have shown fluctuations, with<br />

changes of up to 32%. We recor<strong>de</strong>d 915 breeding pairs of<br />

Gentoo penguin in 2009, 905 pairs in 2010, and 1652 in 2011<br />

an increase of 82.5% (Table 1). The average annual growth<br />

for Gentoo penguin was positive between 1970-1987 and<br />

1987-1988, unlike between the years of 1988-1991 and 1991-<br />

2010, when breeding pairs <strong>de</strong>clined in number (Table 1).<br />

For the Chinstrap penguin, we recor<strong>de</strong>d 3974 breeding<br />

pairs in 2009, 5250 pairs in 2010, and 5279 in 2011 with<br />

increase 32.1% and 0.55% (Table 2). Between 1970-1985,<br />

the population size remained stable (increase 0.28% per<br />

year), unlike between 1986-2010 when fluctuations showed<br />

consi<strong>de</strong>rable increase and <strong>de</strong>cline (Table 2).<br />

Several factors may regulate bird reproductive success,<br />

one of them is the availability of nesting sites (Ainley &<br />

Boekelhei<strong>de</strong>, 1990). Despite the increase in ice-free areas in<br />

the South Shetland Islands, and consequently the exposure<br />

of new places suitable for breeding sites over the years<br />

(Jablonski, 1984), local climate events such as excessive<br />

accumulation of snow and snowstorms limit the nesting<br />

sites of penguins, as observed in our study in December<br />

2009, when many breeding pairs of both species lost<br />

their eggs and abandoned their nests. Food availability,<br />

pre<strong>da</strong>tion and climate change also influence the population<br />

fluctuation of the penguins, and specific behaviors of each<br />

species may help compensate for or mo<strong>de</strong>rate effects of<br />

changing environmental conditions (Miller et al., 2010;<br />

Trivelpiece et al., 2011). Our results show that population<br />

fluctuation for the Elephant Island Gentoo penguins varies<br />

less than for its Chinstrap penguins. Even though the<br />

two species co-exist, they exhibit very different behaviors<br />

in respect to reproduction timing, feeding ecology and<br />

Discussion<br />

Comparing our <strong>da</strong>ta with studies from Furse & Bruce (1972)<br />

and Petry (1994), we can see changes in population size of<br />

Gentoo and Chinstrap penguins, at Stinker Point, Elephant<br />

Island. Such changes are indicative of environment quality<br />

in which a population <strong>de</strong>pends on variable food resources<br />

and it is also important to un<strong>de</strong>rstand and to predict the<br />

effects of environmental change (Croxall et al., 2002). For<br />

long-living birds such as penguins, a 2 to 3% annual change<br />

in population size can be quite significant, and the only way<br />

to evaluate this parameter is through monitoring studies<br />

(Trivelpiece & Trivelpiece 1990).<br />

winter habitat selection (Trivelpiece et al., 1987). There<br />

is evi<strong>de</strong>nce that Gentoo penguins remain in the vicinity<br />

of breeding areas during the winter (Bost & Jouventin,<br />

1990), unlike local Chinstrap penguins which move nearer<br />

to the Antarctic convergence (Williams, 1995; Wilson,<br />

1998; Trivelpiece et al., 2007). Un<strong>de</strong>r adverse conditions<br />

during winter, such as low prey availability and excessively<br />

ice conditions, only old, experienced Chinstrap penguins<br />

return to breeding colonies at the beginning of the breeding<br />

season (Trivelpiece & Trivelpiece 1990). Thus, the survival<br />

of juveniles, their recruitment and return rates to colonies<br />

may be affected by adverse winter conditions, as suggested<br />

by Carlini et al. (2009).<br />

Our results corroborate the evi<strong>de</strong>nce of penguin<br />

population <strong>de</strong>cline reported in Antarctica. Trivelpiece et al.<br />

(2011) suggested conservation status review for Chinstrap<br />

penguin given the magnitu<strong>de</strong> of their global population<br />

<strong>de</strong>cline and limitations of distribution range. In contrast,<br />

Gentoo penguins are circumpolar in distribution and are<br />

more generalist fee<strong>de</strong>rs, giving them a distinct survival<br />

advantage (Bost & Jouventin, 1990).<br />

Conclusion<br />

Yet, we conclu<strong>de</strong> that, at Stinker Point, Elephant Island,<br />

continued monitoring and <strong>de</strong>mographics studies are<br />

nee<strong>de</strong>d for both penguin species to <strong>de</strong>termine with<br />

confi<strong>de</strong>nce whether the observed population <strong>de</strong>cline is a<br />

long-term trend or represents transient local environmental<br />

fluctuations and whether changes in conservation efforts<br />

will be required to maintain future global and regional<br />

populations of these species.<br />

Abstract: We present preliminary results on the foraging distribution of Southern Giant Petrels tagged with geolocators in Stinker<br />

Point, Elephant Island. Our results showed that Giant Petrels range over a large area from the Antarctic Peninsula until Southern<br />

South America, and there is notable segregation between male and female. Females tend to use the area they are distributed<br />

equally, while males remain more often close to colonies, but the latitu<strong>de</strong>s and longitu<strong>de</strong>s they used in general were the same.That<br />

is quite different from literature, which indicate that Giant Petrel gen<strong>de</strong>rs use distinct foraging areas, at least South American<br />

populations. Further results from the study are un<strong>de</strong>rway and we expect to add environmental variables to evaluate differences<br />

between gen<strong>de</strong>rs and try to explain their movements.<br />

Keywords: breeding period, foraging ecology, gen<strong>de</strong>r differences, geolocation<br />

Introduction<br />

Seabirds rely almost exclusively on the sea. They are<br />

bon<strong>de</strong>d to land only for reproduction, and even then, the<br />

resources necessary to raise a brood are from off shore.<br />

Factors influencing on land such as severe weather, gusty<br />

winds, hazardous blizzards can reduce adult survival and<br />

breeding success (Mallory et al., 2009), but the main factors<br />

driving seabird population dynamics are the oceanic factors<br />

(Sandvik et al., 2008; Rolland et al., 2010).<br />

Biotic and abiotic factors are used by seabirds for<br />

gui<strong>da</strong>nce when searching for food, such as productivity, sea<br />

and wind currents, temperature, and so on (A<strong>da</strong>ms & Flora,<br />

2010; Copello et al., 2011). Nonetheless, long time changes<br />

in such factors can affect adult survival and breeding success<br />

(Rolland et al., 2010).<br />

Hence, this paper presents preliminary results on a study<br />

conducted with geolocators on an Antarctic population<br />

of Southern Giant Petrels, aiming to obtain <strong>da</strong>ta on sea<br />

distribution and sea use while foraging.<br />

Materials and Methods<br />

Study was conducted on Stinker Point (61° 07’ 31’’ S and<br />

55° 19’ 26’’ W), Elephant Island, recently presented as<br />

Antarctic IBA 072 (Harris et al., 2011). Stinker Point is the<br />

northernmost island of the South Shetlands, and provi<strong>de</strong>s a<br />

breeding ground for several seabird and seamammal species.<br />

The Southern Giant Petrel SGP is one of the most numerous<br />

seabirds in the area. The SGPs breed on elevated and<br />

relatively plain terrains among 30 and 60 m above sealevel.<br />

We <strong>de</strong>ployed on 11/11/2011 (period of egg laying), 12<br />

Lotek LAT 2009 Avian FlatpackGeolocators in males and<br />

females SGPs from different nests. We attached the tags<br />

ma<strong>de</strong> of aluminum bands with small plastic seals. The tags<br />

were recovered from birds in periods between seven and<br />

fourteen <strong>da</strong>ys after <strong>de</strong>ployment, the <strong>da</strong>ta was downloa<strong>de</strong>d<br />

and then re<strong>de</strong>ployed in other SGPs.<br />

The tags generated <strong>da</strong>ily average geographic positions<br />

based on light intensity and hour of sunrise and sunset.<br />

Positions were filtered by generating a threshold circle with<br />

2 stan<strong>da</strong>rd <strong>de</strong>viation position with ArcGis. All points that<br />

fell out of the threshold line were exclu<strong>de</strong>d. We calculated<br />

Kernel <strong>de</strong>nsity to estimate the most frequently used areas<br />

by those individuals. We compared Latitu<strong>de</strong> and Longitu<strong>de</strong><br />

between gen<strong>de</strong>rs and in different months (November,<br />

December and January) with a Repeated Measures ANOVA<br />

to <strong>de</strong>tect differences in areas used by gen<strong>de</strong>rs.<br />

Results<br />

We were able to monitor 18 SGPs (7 males and 11 females)<br />

during all the breeding period. The filtering resulted in a<br />

total of 178 points entering the analysis. From a first visual<br />

inspection of the Kernel Density distribution, both males<br />

and females used similar areas, comprising the Antarctic<br />

Peninsula until Southern South-America (Tierra <strong>de</strong>l<br />

Fuego, near 55° S), a small portion of the South Pacific<br />

until longitu<strong>de</strong>s near South Orkneys and South Georgia<br />

35° W. (Figure 1). Even females generated more points than<br />

males, they generated smaller <strong>de</strong>nsities than males, probably<br />

indicating they forage in a more dispersed way.<br />

Latitu<strong>de</strong> is not different between gen<strong>de</strong>rs (F 1,166<br />

= 0.1;<br />

P = 0.76), but is different in months (F 2,166<br />

= 0.3; P = 0.04)<br />

(Figure 2). No variation of gen<strong>de</strong>r latitu<strong>de</strong> usage was<br />

<strong>de</strong>tected along the months (F 2,166<br />

= 0.5; P = 0.63). Longitu<strong>de</strong><br />

is not different between gen<strong>de</strong>rs (F 1,166<br />

= 0.05; P = 0.83),<br />

nor among months (F 2,166<br />

= 2.3; P = 0.1) and no variation<br />

of gen<strong>de</strong>r longitu<strong>de</strong> usage was <strong>de</strong>tected along the months<br />

(F 2,166<br />

= 0.06; P = 0.94).<br />

Discussion<br />

Our results clearly indicate males forage in more frequency<br />

near the colony than females, and as a consequence tend<br />

to enhance Kernel <strong>de</strong>nsity in the areas they are using.<br />

On the other hand, females’ frequencies are lower along<br />

their entire distribution. These are the first results on<br />

foraging movements of Antarctic SGPs. Some results are<br />

in accor<strong>da</strong>nce with studies on South American Giant Petrel<br />

populations (González-Solís et al., 2000; Copello et al.,<br />

2011). Our study is in accor<strong>da</strong>nce with literature which<br />

indicates that female frequency is homogeneous along<br />

their distribution while males tend to concentrate close to<br />

their colonies. But in matters of distribution, our results<br />

are in disagreement with those found for South American<br />

populations since there are no latitudinal or longitudinal<br />

differences between gen<strong>de</strong>rs. There is a marked difference<br />

between male and female distribution between gen<strong>de</strong>rs<br />

in both Giant Petrel species (González-Solís et al., 2000;<br />

Copello et al., 2011). Copello et al. (2011) verified a<br />

slight difference between southern and northern colonies<br />

Figure 2. Average latitu<strong>de</strong> used by Southern Giant Petrels in November,<br />

December and January in 2011/12 summer. Error bars are stan<strong>da</strong>rd error.<br />

in Argentina, so, differences in foraging behavior can<br />

be attributed to the southern position of Stinker Point<br />

population, as a consequence their behavior is different<br />

from northern populations. Quintana & Dell'Arciprete<br />

(2002) and Copello et al. (2011) tagged birds in the late<br />

incubation period and verified birds remained closer to<br />

their colony, while ours showed differences in areas used<br />

along the breeding period.<br />

Conclusion<br />

Males and females range over the same portion of the<br />

ocean with a high overlap, which is quite different from<br />

literature information. Such differences may be due to a<br />

natural geographical variation of the species and because<br />

of the period the <strong>da</strong>ta was collected. The perspective of<br />

including in the analysis variables such as sea temperature<br />

and productivity will help us extend our explanations on<br />

male-female differences.<br />

Introduction<br />

With the intensification of human activities in Antarctica<br />

and the increased speed of environmental change in the area<br />

of the Antarctic Peninsula, it is of fun<strong>da</strong>mental importance<br />

to give continuity to the long term ecological studies in the<br />

region, in or<strong>de</strong>r to un<strong>de</strong>rstand and predict the effects of<br />

those anthropic and natural changes on the structure and<br />

functioning of Antarctic marine ecosystems. Environmental<br />

monitoring not only permits the evaluation of temporal<br />

trends in the ecosystem properties and functions, but also<br />

subsidises the management and conservation of these<br />

environments, fulfilling the environmental commitments<br />

assumed by Brazil with the member countries of the<br />

Antarctica Treaty. Furthermore, the main studied area<br />

of the marine environmental studies of INCT-APA,<br />

(Portuguese acronym for: The Brazilian Institute of Science<br />

and Technology – Antarctic Environmental Research)<br />

has been the Admiralty Bay, at King George Island, a<br />

recognisably diverse environment (Siciński et al., 2011).<br />

The bay functions as a feeding and breeding area for a great<br />

number of marine species, the whole area being consi<strong>de</strong>red<br />

as an ASMA (Antarctic Specially Managed Area).<br />

The results obtained at the moment, indicate a marine<br />

environment whose physical and chemical characteristics<br />

of the sea water (e.g. water temperature and pH), present<br />

a strong relationship with the air temperature, apart from<br />

indicating the existence of upwelling episo<strong>de</strong>s close to the<br />

main research stations in the Bay, namely, EACF (Portuguese<br />

acronym for: The Brazilian Station – Coman<strong>da</strong>nte Ferraz)<br />

and Arctowski (The Polish Station) (Cascaes et al., in the<br />

volume), which could cause a greater spatial and temporal<br />

variation in the local primary production. In the water<br />

column, the marine phytoplankton has been shown to be<br />

a good indicator of environmental quality. Data from the<br />

last ten years suggest that the abun<strong>da</strong>nce and composition<br />

of the phytoplankton has altered over the years, with a<br />

gradual substitution of microplankton (diatomaceous) by<br />

pico–and ultra-plankton (cells < 10 µm), especially at the<br />

end of summer, which can be reflecting an increase of the<br />

ice-free zones in the region (Barrera-Alba et al., in this<br />

volume). If these changes are confirmed over the next few<br />

years, the consequences could reflect even on the spatial<br />

distribution of Krill in the area, since the latter is unable<br />

to efficiently consume the pico- and ultra plankton. The<br />

dominance of the copepods in the zooplankton in the Bay<br />

has been evi<strong>de</strong>nt, in spite of the significant contribution<br />

of the larvae of echino<strong>de</strong>rms for the local meroplankton<br />

(Kern et al., in this volume).<br />

The monitoring of the marine environment close to<br />

EACF has been un<strong>de</strong>rtaken for the correct evaluation of<br />

the impact of human activities in the marine biota of Martel<br />

inlet and counts with the monitoring of temporal domestic<br />

effluents from the Brazilian Station. In studies carried out<br />

in the summer of 2011, the results showed an increase in<br />

the efficiency of the sewage treatment system at EACF, with<br />

the efficient removal of coliforms and enterococci (between<br />

80-100%), after UV treatment, although inefficient in the<br />

removal of nutrients, suggesting that the treatment system<br />

still nee<strong>de</strong>d to be optimized (Nakayama et al., in this<br />

volume). In spite of the recent fire at the Brazilian Station,<br />

the <strong>da</strong>ta generated by this monitoring is important, since<br />

it can be used as a gui<strong>de</strong> to the installation of more proper<br />

facilities with a minimal of environmental impact at the new<br />

Brazilian Station which will be constructed in the next years.<br />

The faecal sterols and linear alkylbenzenes (LABs) are<br />

excellent geochemical markers of sewage since they are<br />

resistant to rapid environmental <strong>de</strong>gra<strong>da</strong>tion, permitting<br />

mapping out of the range and effect of the sewage in the<br />

marine environment. Data of these markers in the sediment<br />

of Admiralty Bay indicate a greater concentration in the<br />

vicinity of EACF, but with a ten<strong>de</strong>ncy to reduce in relation<br />

to the summer 2003/04, but with consi<strong>de</strong>rably lower values<br />

when compared to other regions of Antarctica. Between<br />

these two types of sewage markers, the LABs show a<br />

potential to be a more specific sewage marker, since their<br />

<strong>de</strong>tectable values were only found close to the EACF sewage<br />

(Martins et al., in this volume). The sterols can also be<br />

used in historic analysis of the contribution of the different<br />

forms of organic material (marine, terrestrial, anthropic) to<br />

the sediment, thus assisting in the evaluation of temporal<br />

variations of the biogeochemical processes (Wisnieski et al.,<br />

in this volume).<br />

Among the marine habitats that can be affected by human<br />

activities or even by climate change, the interti<strong>da</strong>l zone is<br />

the first to suffer from those environmental alterations. The<br />

most conspicuous organism in this region is the gastropod<br />

Nacella concinna, which<br />

has been consi<strong>de</strong>red to be a sentinel species due to<br />

its capacity to accumulate metals (Ahn et al., 2002) or<br />

to be sensitive to the effect of pollutants (Ansaldo et al.,<br />

2005). Up till now, no significant anthropic effect<br />

was found in the populations that inhabit Admiralty<br />

Bay, <strong>de</strong>spite a certain accumulation of heavy metals<br />

found in the species, as well as in a number of benthic<br />

invertebrates in the region (Majer et al., in this volume).<br />

However, studies with biochemical biomarkers reveal a<br />

sensibility of several enzymes in this organism, such as<br />

arginases, phosphofructokinase and catalase, to increasing<br />

concentrations of diesel oil (Feijó <strong>de</strong> Oliveira et al., in this<br />

volume), reinforcing the importance of control methods<br />

for the prevention of oil leaks into the marine environment<br />

of the region.<br />

Even in the sublittoral zone, in water <strong>de</strong>pths of less<br />

than 20-30m, some effect of the effluent of the Station<br />

can be noticed (Montone et al., in press). Fish and benthic<br />

invertebrates un<strong>de</strong>rgo alterations over the time, when<br />

submitted to chronic (sewage) or acute impacts (oil leakages,<br />

for example). Among the fish, most of the nothotenioids<br />

are en<strong>de</strong>mic to Antarctica, which increases the ecological<br />

importance in terms of preservation and conservation of<br />

the marine environment. Through the usage of biochemical<br />

and histological biomarkers, possible alterations in those<br />

fishes can be <strong>de</strong>tected. The histological analysis of the fishes<br />

N. coriiceps and N. rossi showed some changes in the liver<br />

and gills which are still of low occurrence, not affecting the<br />

functionality of their organs and as consequence, not having<br />

any lethal significance (Donatti et al., in this volume). The<br />

same seems to occur with the analyses of the plasmatic<br />

composition of these fish, with variation of glucose,<br />

trygliceri<strong>de</strong>s, cholesterol, total protein and albumins more<br />

related to local physical and chemical differences than to<br />

anthropic ones (Rodrigues Junior et al., in this volume).<br />

For the benthic macroinfauna, the main changes occur<br />

in the abun<strong>da</strong>nce and dominance of species in a range of<br />

200m from EACF (Montone et al., in press). In spite of the<br />

presence of metals in the sediment, analyses consi<strong>de</strong>ring the<br />

mobility of some of these metals, revealed that just Arsenic<br />

and Copper show values that could represent some risk<br />

to the biota (Ribeiro et al., in this volume), emphasising<br />

the importance of evaluating the bioavailability of these<br />

substances in or<strong>de</strong>r to evaluate the real effect on marine<br />

organisms.<br />

One of the greatest threats to Antarctic marine<br />

biodiversity, with a high <strong>de</strong>gree of en<strong>de</strong>mism, is the<br />

introduction of exotic species, whether through human<br />

action or through the increase of the temperature of the<br />

oceans, allowing the spread of Sub-Antarctic species to<br />

the Antarctic region. The potential of bioinvasion in the<br />

Antarctic environment is directly related to the increase of<br />

human activities in the region, especially those related to<br />

the increase in the traffic of vessels, one of the main vectors<br />

in the introduction of species in the marine environment.<br />

A recent survey (Rocha et al., in this volume) indicated an<br />

intensification of human activities, such as tourism, fishing<br />

for Krill and scientific activity on King George Island, in<br />

the last five years, which could represent a greater risk of<br />

introduction of exotic species.<br />

In this context, a study of the local biodiversity is<br />

important to get to know the <strong>de</strong>gree of vulnerability of<br />

the Antarctic marine biota to invasions of exotic species<br />

in the future. Despite recent efforts related to the marine<br />

benthic species inventory in Admiralty Bay (Siciński et al.,<br />

2011), there is still a lot to do regarding the comprehensive<br />

knowledge of the marine biodiversity of the region.<br />

Recent <strong>da</strong>ta regarding the composition of the associated<br />

macrofauna to the kelp Himantothallus grandiflorius<br />

(Campos et al., in this volume), for example, revealed an<br />

abun<strong>da</strong>nt and diverse biota, composed mainly of amphipods<br />

and lophophorates, which still need taxonomic refinement<br />

and which could add new species or new records to this<br />

region. Apart from the latter, the interaction between the<br />

94 | Annual Activity Report 2011


terrestrial and marine environment takes place through<br />

the collaboration of researchers who study the biodiversity<br />

of the two environments in an integrated way. The phytal<br />

fauna, for example, is studied not only in terms of marine<br />

environment, but also in the terrestrial environment, as in<br />

the study of the associated meiofauna of Prasiola crispa,<br />

(Dalto et al., in this volume), which is quite abun<strong>da</strong>nt in<br />

the proximities of the penguin colonies of Arctowski Polish<br />

Station. The results show a biota dominated by Tardigra<strong>de</strong>s<br />

and Nemato<strong>de</strong>, which in the same way as in the marine<br />

environment, can add an expressive number of species to<br />

the biological inventory of Admiralty Bay.<br />

Abstract: Classic hydrographical parameters and dissolved nutrients were measured during the Antarctic summers from 2009<br />

to 2012. Physical and biological processes control the nutrient levels in Admiralty Bay, as well as upwelling of <strong>de</strong>ep water from<br />

Bransfield Strait. Additional <strong>da</strong>ta on summer land run-off and wind speeds and directions is nee<strong>de</strong>d to get a better mo<strong>de</strong>l for the<br />

factors that control the primary production of the area.<br />

Keywords: nutrients, pH, dissolved oxygen, Antarctica<br />

Introduction<br />

Admiralty Bay is a well-studied marine sub Antarctic<br />

environment due to the five research stations (Poland, Brazil,<br />

Peru, Equator and U.S.A) established there since the sixties.<br />

Hydrographical studies of the area have been ma<strong>de</strong> since<br />

1980 by scientists of the Polish Research Station of Arctowski<br />

(Pruszak, 1980; Lipski, 1987; Rakusa-Suszcewski et al.,<br />

1993) and Brazilians from the Ferraz Station (Brandini &<br />

Rebello, 1994).<br />

Further <strong>da</strong>ta of nutrients, dissolved oxygen (DO) and<br />

phytoplankton distribution were summarized by Weber &<br />

Montone (2006). Although there is no scarcity of previous<br />

summer <strong>da</strong>ta, a coherent general pattern could not be<br />

observed due to strong yearly variations. This may reflect<br />

the irregular pattern of terrestrial ice melting and of the<br />

irregular land run-off contributions which are not quantified<br />

on a systematic basis.<br />

The present study reports the temperature, salinity,<br />

dissolved nutrients, dissolved oxygen and pH variations<br />

during the summers of 2009/2010/2011/2012 (from<br />

OPERANTAR XXVII to OPERANTAR XXIX) in five points<br />

of Admiralty Bay near EAFC (Portuguese acronym for<br />

Coman<strong>da</strong>nte Ferraz Antarctic Brazilian Research Station)<br />

and Arctowski Research Stations at three <strong>de</strong>pths.<br />

Materials and Methods<br />

The location of the Sampled Station areas is shown on<br />

Figure 1 and Table 1. The water was collected at 0, 15 and<br />

30 m <strong>de</strong>pth.<br />

Water sampling was done with a peristaltic pump<br />

(Anauger 900 - flow rate of 1200 L h –1 at 30 m <strong>de</strong>pth and<br />

2.300 L h –1 at the sea surface) and the temperature was<br />

measured with temperature sensor (Seamon Mini) attached<br />

to the pump. The samples and the analysis of dissolved<br />

oxygen (DO), pH, nitrite, nitrate, phosphate and silicate<br />

was done according Grasshoff et al. (1983).<br />

Results<br />

In Table 1 we show the oceanographic parameters in<br />

Admiralty Bay: temperature, salinity, dissolved oxygen, pH,<br />

phosphate, silicate and nitrite. The table presents average,<br />

s.d., minimum and maximum of each phase.<br />

Temperature differences were significant between<br />

November and March. In contrast, pH values also presented<br />

significant differences along the sampling periods, which<br />

were expected, but did not affect the pH values. For example,<br />

in the 3 rd Phase of OPERANTAR XXIX we had the lowest<br />

pHs although temperatures were at their highest.<br />

(between November and December) and 3rd phase<br />

OPERANTAR XXVIII (between January and February)<br />

show higher values without significant differences.<br />

Our salinity and temperature is closer to the <strong>da</strong>ta of<br />

<strong>de</strong>eper water of Admiralty Bay (Lipski, 1987; Sarukhanyan<br />

& Tokarczyk, 1988; Weber & Montone, 2006).<br />

Nitrate and nitrite also showed significant variations<br />

between the different sampling periods.<br />

In the third phase of OPERANTAR XXVIII, phosphate<br />

concentrations were uniform during all phases of sampling.<br />

Discussion<br />

The upper mixed layer of Admiralty Bay is between 15 up to<br />

35 m (Brandini, 1993). Vertical mixing is very intense so no<br />

stratification can occur (Prusza, 1980; Nedzarek & Rakusa-<br />

Suszczewski, 2004).This study is limited to this upper layer,<br />

therefore a homogeneity of the hydrographical <strong>da</strong>ta along the<br />

water column is expected. Jażdżewski et al. (1986) showed<br />

that there was a uniform pattern of the hydrographical <strong>da</strong>ta<br />

between the different areas of Admiralty Bay.<br />

An increase in temperature between the beginning and<br />

the end of Antarctic summer is normal (Brandini & Rebello,<br />

1994; Lange et al., 2006). Air temperature can oscillate from<br />

0,5 up to 2,0° Celsius in the summer (INPE, 2011). March<br />

of OPERANTAR XXVIII, however was anomalous. Instead<br />

of increasing as normally expected like in OPERANTAR<br />

XXIX, OPERANTAR XXVII it sinked from 0,8 to 0,2 o C<br />

(INPE, 2011).<br />

As well as the temperature, pH values ​varied wi<strong>de</strong>ly, but<br />

they have not always been correlated, as shown in Table 1.<br />

pH is also influenced by photosynthesis or organic matter<br />

<strong>de</strong>gra<strong>da</strong>tion. To be sure about the biological variables<br />

affecting pH it will be necessary to compare our <strong>da</strong>ta with the<br />

other <strong>da</strong>ta of Module 3 projects INCT-APA. Salinity (PSU)<br />

did not show significant differences in all sampling periods.<br />

Lange et al. (2007), studying Admiralty Bay, reported an<br />

increase in temperature of the surface water but no salinity<br />

changes during the summer. We registered a small difference<br />

in salinity due to an iceberg positioned near Botany Point in<br />

the first phase of this OPERANTAR. Comparing our results<br />

with other authors who studied the area we can perceive<br />

differences. Salinity and temperature for instance are not<br />

the same as reported by other authors for the area.<br />

WSW and NWN winds carry the surface waters of<br />

the inlet in the direction of the Bransfield Strait. This<br />

process creates an inflow of <strong>de</strong>ep water to Admiralty Bay<br />

(Pruszak, 1980; Robakiewicz & Rakuza-Swazcsewski,<br />

1999). As this Bay is influenced by the water masses of<br />

Wed<strong>de</strong>ll Sea, col<strong>de</strong>r and more saline (–0,75 C - 33,50 psu)<br />

and of the Bellinghausen Sea, warmer and less saline<br />

(2,25 C - 34,40 psu) (Weber & Montone, 2006) a small<br />

upwelling on Admiralty Bay may occur.<br />

Therefore our <strong>da</strong>ta has bottom water characteristics<br />

which is more evi<strong>de</strong>nt when looking at the dissolved<br />

oxygen <strong>da</strong>ta whose values are close to the bottom water<br />

and lower than those of the surface waters (Samp, 1980;<br />

Rakusa-Suszczewski, 1995). The first phase of sampling<br />

on OPERANTAR XXIX presented the highest DO<br />

concentrations. The other samples showed lower dissolved<br />

oxygen levels. Oxygen levels are controlled by physical<br />

factors as well as affected by all biological processes of the<br />

water column of the study area. Silicate concentrations for<br />

the first phase of OPERANTAR XXIX were greater than the<br />

average value for all other phases (Table 1).<br />

On this particular phase we observed a Pteropo<strong>da</strong> bloom,<br />

which may be associated with a higher availability of silicate.<br />

Pteropo<strong>da</strong> are plankton grazers eating mainly diatoms<br />

and dinoflagellates as well as small crustaceans (Boersma,<br />

1978). Silicate is the limiting nutrient for diatoms growth.<br />

Increase of the diatom number may be associated with<br />

higher dissolved oxygen as pointed out before. To be sure<br />

of this correlation we had to integrate our chemical <strong>da</strong>ta<br />

with phytoplankton <strong>da</strong>ta form Module 3 studies. Higher<br />

silicate concentrations for the beginning of summer (first<br />

phase) may have been associated with the non utilization<br />

98 | Annual Activity Report 2011


of silicate during the winter months due to the absence of<br />

light. Furthermore upwelling can occur in Admiralty Bay<br />

as shown by (Rakuza-Swazczewski, 1980) which enhances<br />

the silicate levels.<br />

Significant variations of the parameters nitrite and<br />

nitrate were observed. High productivity in the first phase of<br />

OPERANTAR XXIX may be responsible for the high nitrite<br />

concentrations and low nitrate concentrations.<br />

Many biological and physical variables affect the<br />

chemistry of the water column. To infer which processes<br />

predominate, it will be necessary to integrate our <strong>da</strong>ta with<br />

the other sub-projects of Module-3.<br />

Conclusions<br />

Sea surface temperature relates directly to air temperature.<br />

pH is related to air temperature and water temperature.<br />

Changes of pH between different phases of sampling<br />

was not associated with seawater temperature. There are<br />

occasional upwelling episo<strong>de</strong>s near EACF and Arctowski<br />

Stations. Dissolved oxygen in seawater is related to primary<br />

productivity or strong wind fields.<br />

Abstract: The phytoplankton composition and biomass are being monitored in Admiralty Bay, Antarctic Peninsula since 2002 to<br />

<strong>de</strong>tect possible interannual changes on a long-term monitoring perspective. In this report, we present the results of the December<br />

2010 survey regarding the phytoplankton size-structure and biomass. Microplankton <strong>de</strong>nsities were higher than those observed<br />

during the survey 2009/2010, and a dominance of diatoms, especially the centric Thalassiosira spp, over dinoflagellates was<br />

registered. Pico and ultraplankton <strong>de</strong>nsities (~10 6 cells L –1 ) were similar to those registered in previous studies, and results showed<br />

that phytoplankton were dominated in <strong>de</strong>nsity by cells


we show the results from early summer obtained during the<br />

OPERANTAR XXIX, December 2010.<br />

Materials and Methods<br />

Study area<br />

Admiralty Bay (62° 03’-12’ S and 58° 18’-38’ W), located at<br />

King George Island, is a <strong>de</strong>ep fjord-like embayment with 500<br />

m maximum <strong>de</strong>pth at its centre (Rakusa-Suszczewski et al.,<br />

1993). The waters from the bay mix with the <strong>de</strong>ep oceanic<br />

waters from Bellingshausen and Wed<strong>de</strong>ll Seas at its southern<br />

opening, which connects to the Bransfield Strait (Rakusa-<br />

Suszczewski, 1980). The maximum <strong>de</strong>pth varies between<br />

60 m along the shores and 500 m in the centre of the bay.<br />

Deep currents generated by ti<strong>de</strong>s, frequent upwellings,<br />

vertical mixing of the entire water column and current<br />

velocities of 30-100 cm s −1 in the 0-100 m surface stratum are<br />

characteristic of the bay (Rakusa-Suszczewski et al., 1993).<br />

In the context of water column production, Admiralty Bay<br />

at nearshore can be consi<strong>de</strong>red as Platt et al. (2003) <strong>de</strong>fined<br />

as “high nutrient – low chlorophyll (HNLC): showing high<br />

inorganic dissolved nitrogen (16.6-46.9 µM) and phosphate<br />

(0.2-9.9 µM) concentrations, while chlorophyll levels are<br />

lower than 1.7 µg L –1 (Lange et al., 2007).<br />

Sampling<br />

The analysis of pico-, ultra- and microplankton and<br />

chlorophyll was performed from splits of the 5 L water<br />

samples collected by Van Dorn bottle from surface, middle<br />

water column and near the bottom (≈30 m) at five sites<br />

in December 2010. The Admiralty Bay location and the<br />

position of the sampling sites are shown in Figure 1.<br />

Water temperature and salinity were analysed by the<br />

Laboratório <strong>de</strong> Química Orgânica Marinha (LabQOM),<br />

Fixation and preparation of samples<br />

For pico- (10 µm), 1 L were fixed with buffered<br />

formal<strong>de</strong>hy<strong>de</strong> (2% f.c.) and kept in the <strong>da</strong>rk immediately<br />

after sampling. At the laboratory, samples were analysed<br />

using the settling technique (Utermöhl, 1958) in an Olympus<br />

IX70® inverted microscope with 400× magnification. For<br />

chlorophyll biomass, 2L were filtered onto Whatman® GF/F<br />

for total pigments analyses, while 0.8-2 L was used for the<br />

size structure study. In the latter case, water sampled at<br />

3 <strong>de</strong>pths was fractionated by serial filtration on 10 μm and<br />

2 μm polycarbonate filters and GF/F. The filters were fol<strong>de</strong>d,<br />

placed into a 1.2 mL cryotube and immediately quickfrozen<br />

in liquid nitrogen (−196 °C) and stored at −80 °C.<br />

Concentrations of chlorophyll a (Chl.a) were assessed using<br />

a modified version of Neveux and Lantoine’s (1993) method.<br />

In or<strong>de</strong>r to normalize distributions and eliminate<br />

zero values, the biological <strong>da</strong>ta was transformed using<br />

log10 (x + 1). Pearson’s correlation factor was also calculated.<br />

Results<br />

Salinity showed little variation (34.2 ± 0.1) between sampling<br />

sites and <strong>de</strong>pths, while a higher variation was observed in<br />

water temperature (0.30 ± 0.15 °C). Except for BP, water<br />

temperature <strong>de</strong>creased with <strong>de</strong>pth, with values of 0.14 at<br />

surface and 0.73 near the bottom. Total chlorophyll biomass<br />

varied between 0.36 and 0.84 µg L –1 (0.54 ± 0.12 µg L –1 ),<br />

with higher values registered at BP, and the fraction > 10 µm<br />

represented more than 50% (Figure 2b). An average cellular<br />

<strong>de</strong>nsity of 1.9 × 10 7 ± 0.4 × 10 7 cells L –1 was observed for total<br />

autotrophic plankton, with a maximum value of 2.2 × 10 7<br />

cells L –1 observed at TP. The dominant fractions were<br />

pico (mean 79%) and ultraplankton (mean 20.9%) for all<br />

samples sites (Figure 2C). For microplankton, an average<br />

cellular <strong>de</strong>nsity of 8.8 × 10 3 ± 3 × 10 3 cells L –1 was observed,<br />

with a maximum value of 16.4 × 10 3 cells L –1 observed<br />

at BP (Figure 2d). In general, no statistically significant<br />

correlations were observed between <strong>de</strong>nsities and salinity,<br />

temperature or Chl.a. Only microphytoplankton showed a<br />

positive correlation with total chlorophyll biomass (r = 0.77,<br />

p < 0.05). The contribution was shared by the diatoms<br />

(mean 72 %) and dinoflagellates (mean 27%) (Figure<br />

2d). Among centric diatoms was predominant (92%),<br />

mainly the genera Thalassiosira. Thecate forms, especially<br />

Prorocentrum cf. antarcticum, were more abun<strong>da</strong>nt among<br />

dinoflagellates (56%).<br />

Spatially, autotrophic picoplankton <strong>de</strong>nsities generally<br />

<strong>de</strong>creased from the external region (AR-TP) to inner<br />

sampling stations (CF-BP). Ultraplankton contribution did<br />

not show great spatial differences. An inverse pattern was<br />

observed for microphytoplankton and diatom contribution,<br />

with higher <strong>de</strong>nsities observed in BP and bottom samples.<br />

Discussion<br />

Microplankton cellular <strong>de</strong>nsities and chlorophyll biomass<br />

observed in this study were low when compared to those<br />

registered for Admiralty Bay during the <strong>de</strong>ca<strong>de</strong>s of the<br />

1970s, 1980s and 1990s, when <strong>de</strong>nsities of 10 5 cells L –1<br />

were usually registered (i.e. Kopczynska, 2008). However<br />

mean <strong>de</strong>nsities were six times higher than those observed<br />

by Lange et al. (2007) in a study <strong>de</strong>veloped during the<br />

austral summer 2002/2003, and three times higher<br />

than the means registered during the austral summer<br />

2009/2010 (Tenenbaum et al., 2011a). The dominance of<br />

diatoms over dinoflagellates in early summer 2010 is a<br />

characteristic of microplankton community for Admiralty<br />

Bay (Lange et al., 2007; Kopczynska, 2008). But, during<br />

the study <strong>de</strong>veloped at 2009/2010, a <strong>de</strong>creasing (

chlorophyll a concentrations; c) pico and ultraplankton <strong>de</strong>nsities; and d) microphytoplankton <strong>de</strong>nsity and contribution of main groups to microphytoplankton<br />

temperatures measured in the present study were higher<br />

than those registered for early summer in previous<br />

studies, when negative values were usually registered<br />

for December. In a different way to those related in<br />

previous studies, the centric diatoms Thalassiosira spp.<br />

dominated in early summer 2010/2011. Lange et al. (2011)<br />

<strong>de</strong>scribed this genera as one of predominant microalgae<br />

during late summer 2002/2003, while in early summer<br />

usually pennate diatoms were dominant. Densities<br />

of pico and ultraplanktonic fraction of autotrophic<br />

community were similar (~10 6 cells L –1 ) to those observed<br />

in a previous study during the late summer 2009/2010<br />

(Tenenbaum et al., 2011a), and were co-dominant of the<br />

phytoplankton community in Admiralty Bay. The <strong>de</strong>nsities<br />

of picoautotrophs were also in the same range of the values<br />

observed in other Antarctic regions (Delille et al., 2007). In<br />

the nearshore coastal waters along the Antarctic Peninsula,<br />

a recurrent shift in phytoplankton community structure,<br />

from diatoms to cryptophytes, has been documented due to<br />

high temperatures along the Peninsula increasing the extent<br />

of coastal melt-water zones promoting seasonal prevalence<br />

of cryptophytes (Moline et al., 2004). Even the dominance<br />

of pico and ultra-size cells in phytoplankton, which are not<br />

grazed efficiently by Antarctic krill, will likely cause a shift<br />

in the spatial distribution of krill and may allow also for<br />

the rapid asexual proliferation of carbon poor gelatinous<br />

zooplankton, salps in particular (Moline et al., 2004), our<br />

results show that microphytoplankton biomass (>10 µm),<br />

especially diatoms, represent a high percentage of total<br />

phytoplankton biomass.<br />

Conclusion<br />

In the context of the regional warming trend of WAP,<br />

results of the present study showed a shift in Admiralty<br />

Bay plankton community in relation to the study <strong>de</strong>veloped<br />

during the austral summer 2009/2010, when contribution<br />

of diatoms <strong>de</strong>creased and low microplankton <strong>de</strong>nsities,<br />

dominance of dinoflagellates, mainly heterotrophs, and high<br />

contribution of autotrophs pico- and ultraplankton to total<br />

<strong>de</strong>nsity and biomass in late summer, suggested that changes<br />

could be occurring in Admiralty Bay food web. On the other<br />

hand, the dominance of a large diatom community and the<br />

increasing of microphytoplankton <strong>de</strong>nsities, indicate that it<br />

is necessary to continue the long-term monitoring program<br />

and the implementation of microvariation sampling<br />

effort to i<strong>de</strong>ntify the factors that are actually influencing<br />

phytoplankton populations in this environment.<br />

Abstract: This study aims to provi<strong>de</strong> <strong>da</strong>ta on the abun<strong>da</strong>nce and distribution of zooplankton related to oceanographic parameters<br />

of the coastal environment of Admiralty Bay. In December 2009, during the XXVIII Brazilian Expedition, biological samples and<br />

physic-chemical <strong>da</strong>ta were obtained in four shallow areas, located in front of research stations and a reference area at Botany<br />

Point. A total of 15,882 organisms were sorted from 55 samples resulting in a total <strong>de</strong>nsity of 3.03 organisms/100 m 3 . Nineteen<br />

taxa were i<strong>de</strong>ntified. The most abun<strong>da</strong>nt holoplanktonic organism was copepods and meroplanktonic was echino<strong>de</strong>rms. The PCA<br />

analysis emphasized the importance of phosphate and dissolved oxygen for holoplankton, as nitrite and water temperature for the<br />

meroplankton during the four <strong>da</strong>ys of sampling.<br />

Keywords: holoplankton, meroplankton, monitoring, Admiralty Bay<br />

Introduction<br />

Zooplankton is a component of the plankton constituted<br />

by a diversified group of organisms that live in the water<br />

column of the oceans. They have an important role in<br />

the recycling of nutrients and are divi<strong>de</strong>d in two groups:<br />

Holoplankton (stay in the plankton during all their life cycle)<br />

and Meroplankton (in the plankton during a part of their<br />

life cycle). Some zooplanktonic organisms are consi<strong>de</strong>red<br />

good hydrological indicators (Boltovskoy, 1981), enabling<br />

the i<strong>de</strong>ntification of different sources of water inputs that<br />

comprise the dynamic of an area. Montu & Cor<strong>de</strong>iro (1986)<br />

accomplished the first Brazilian study on the Antarctic<br />

zooplankton in the summer of 1982/1983 during the First<br />

Brazilian Scientific Expedition to Antarctica. Freire et al.<br />

(1993) and Santos (1995) studied the zooplankton of<br />

Admiralty Bay, Subsequent scientific works by the Antarctic<br />

Brazilian program concentrated mainly in the meroplankton<br />

(Absher et. al., 2003; Freire et al., 2006).<br />

In Admiralty Bay, with the beginning of the austral<br />

summer (November-March), starts the supply of larvae<br />

or juveniles from the water column or sediment adjacent<br />

regions (Freire et al., 2006). The lower variability in<br />

temperature and salinity favor an environment with almost<br />

no barriers to larval dispersal however is limited by the<br />

type of reproduction. With the purpose to contribute to<br />

the monitoring program INCT- APA - Thematic Module 3,<br />

this study aims to provi<strong>de</strong> <strong>da</strong>ta on the abun<strong>da</strong>nce and<br />

distribution of zooplankton related to oceanographic<br />

parameters of the coastal environment of Admiralty Bay.<br />

Materials and Methods<br />

The samples were collected from four shallow areas near<br />

research stations and one reference area at Botany Point, in<br />

the <strong>da</strong>ys 11, 15, 23 and 12/29/2009 (Figure 1).<br />

Plankton samples were collected in three replicates in all<br />

stations from five minutes oblique tows at 2 knots from the<br />

sea bottom (30 m) to the water surface. A conical net with<br />

a 150 µm mesh size and 60 cm diameter equipped with a<br />

flowmeter was used. Samples were preserved in 4% buffered<br />

formal<strong>de</strong>hy<strong>de</strong>. Zooplankton organisms were i<strong>de</strong>ntified in<br />

high taxonomic levels and separated in meroplankton or<br />

holoplankton. The values have been corrected to a stan<strong>da</strong>rd<br />

100 m 3 .<br />

In or<strong>de</strong>r to evaluate the community structure of<br />

zooplankton in relation to oceanographic dynamics the<br />

following characteristic of the water were <strong>de</strong>termined: water<br />

temperature (°C), salinity, transparency (m), dissolved<br />

oxygen (DO – mL L –1 ), pH, phosphate (PO 4<br />

– μmol L –1 ),<br />

silicate (SiO 4<br />

– μmol L –1 ), nitrite (NO 2<br />

– μmol L –1 ) and nitrate<br />

(NO 3<br />

– μmol L –1 ).<br />

One-way analysis of variance (ANOVA) was used to<br />

<strong>de</strong>termine the statistical difference in the <strong>de</strong>nsity and<br />

diversity of taxa among sampling <strong>da</strong>ys and stations.<br />

Principal Component Analysis (PCA) on a correlation<br />

matrix was applied to the <strong>da</strong>ta of abun<strong>da</strong>nce, spatial<br />

distribution of zooplankton and environmental <strong>da</strong>ta. When<br />

appropriate a log (x + 1) transformation was employed.<br />

Results<br />

Fifty five samples were collected during the period and a<br />

total of 15,882 zooplankton organisms were sorted. The<br />

total volume of sampled water was approximately 5,238 m 3 ,<br />

resulting in a total <strong>de</strong>nsity of 3.03 organisms.100m -3 . Mean<br />

numbers of holoplankton are shown in Figure 2a. Copepods<br />

dominated in the majority of stations and <strong>da</strong>tes. The average<br />

abun<strong>da</strong>nce was nearly constant among stations during the<br />

sampled period, except for station 4 on 12/15/2009 and<br />

station 5 on 12/29/2009, whose averages were higher. The<br />

mean numbers of meroplankton are shown in Figure 2B.<br />

Meroplankton <strong>de</strong>nsity was high in Machu Picchu station<br />

(St. #3) in the <strong>da</strong>ys 11, 23 and 29 December 2009. On<br />

12/15/2009 was observed the lowest average abun<strong>da</strong>nce<br />

in almost all stations during the sampling period.<br />

Echino<strong>de</strong>rmata and Polychaete larvae were the first and<br />

second most abun<strong>da</strong>nt meroplankton, respectively.<br />

The differences observed in the ANOVA resulting from<br />

the comparison of the <strong>de</strong>nsities (organisms.100m -3 ) between<br />

stations and <strong>da</strong>tes were significant (df = 19; F = 2535;<br />

p < 0.05) and caused mainly by the amount of organisms in<br />

station 4 in 12/15/2009 and 5 in 12/29/2009. The differences<br />

between the abun<strong>da</strong>nces of meroplankton in the stations<br />

and <strong>da</strong>tes were significantly different (ANOVA df = 17;<br />

F = 2.57; p < 0.05).<br />

Mean water temperature during the sampling period<br />

ranged from –0.13 to –0.59 °C. Average salinity ranged<br />

from 33.16 to 34.32, water transparency ranged from 1.80 to<br />

10.50 m, pH from 7.85 to 8.07, dissolved oxygen ranged from<br />

6.46 to 7.56 mL L –1 , phosphate from 1.29 to 2.08 μmol L –1 ,<br />

silicate from 40.53 to 42.63 μmol L –1 , nitrite from 0.02 to<br />

0.17 μmol L –1 and nitrate from 12.94 to 19.69 μmol L –1 .<br />

PCA of holoplankton, meroplankton and environmental<br />

parameters are shown in Figure 3.<br />

The first two components of PCA analyses explain<br />

49.27% of the total variance. Holoplankton abun<strong>da</strong>nce is<br />

influenced by waters with higher DO and phosphate and<br />

less silicate, nitrite, nitrate un<strong>de</strong>r lower pH, wind gust and<br />

speed in less turbid waters. The second factor indicated that<br />

environmental conditions favored meroplankton abun<strong>da</strong>nce<br />

in waters with higher temperature, DO, pH, nitrite, less<br />

phosphate, silicate un<strong>de</strong>r low wind gust in more turbid<br />

waters. While holoplankton had a high correlation with<br />

Factor 1 meroplankton had correlation with Factor 2 and<br />

no correlation to each other.<br />

Discussion<br />

Larval forms are common to different groups of marine<br />

invertebrates which makes conclusive i<strong>de</strong>ntification of the<br />

species almost impossible. Stanwell-Smith et al. (1997) is<br />

the only available source for the i<strong>de</strong>ntification of Antarctic<br />

larvae. Due to the very slow <strong>de</strong>velopment rate of larvae in<br />

Antarctic waters (Bosch et al., 1987; Peck 1993; Peck et al.,<br />

2007; Stanwell-Smith et al., 1999), differences among<br />

larvae from consecutive samples through time may be only<br />

successive stages in <strong>de</strong>velopment of the same specie.<br />

Santos (1995) and Freire et al. (2006) observed that<br />

Polychaeta larvae occurred at the beginning and end of<br />

summer. These results are in accor<strong>da</strong>nce with what was<br />

observed in the present study, as Echino<strong>de</strong>rmata and<br />

Polychaete larvae were <strong>de</strong>tected in the beginning of summer<br />

as the first and second most abun<strong>da</strong>nt meroplankton<br />

respectively. According with Absher & Feijó (1995) mollusk<br />

larvae showed temporal variation, occurring in abun<strong>da</strong>nce<br />

in late summer and almost absent in early summer. In the<br />

present study mollusk larvae occurred in small numbers.<br />

These facts suggest that larvae of invertebrates can be found<br />

differentially throughout the summer. Cruz-Kaled (2011)<br />

found the <strong>de</strong>nsity of veliger larvae of gastropods 124.53<br />

individuals.100m -3 during the summer 2002/2003 and<br />

5.35 individuals.100m -3 during the summer 2003/2004 at<br />

Mackellar Inlet (corresponding to station 3 of the present<br />

study). These <strong>da</strong>ta when compared with the present study<br />

show a large interannual difference in the occurrence of<br />

zooplankton organisms, a situation that can be reflected<br />

throughout Admiralty Bay, probably due to the variation<br />

of oceanographic parameters, reproductive patterns of the<br />

species and the interaction with larvae or adults of other<br />

planktonic organisms.<br />

Near the sampling St #5 (Arctowski) penguin’s species<br />

Pygoscelis antarctica and Pygoscelis a<strong>de</strong>liae can be found<br />

nesting on rocky cliffs in the coastal region. These birds<br />

have a significant impact on the balance of carbon, nitrogen,<br />

phosphorus and other minerals in these nesting areas<br />

(Tatur, 2002). Ornithogenics soils, <strong>de</strong>rived from the activity<br />

of these penguins sampled between Point Thomas (St #4)<br />

and Ecology Glacier showed a high content of phosphate,<br />

as observed by Schaefer et al. (2004). According to Bremer<br />

(2008), the combination of nesting habitats with shallow<br />

soils allows organic matter to accumulate and some of<br />

the material returns to the sea by surface drainage or by<br />

percolation.<br />

The dynamics of the water circulation and the wind<br />

regime of the bay associated to the presence of the<br />

research stations and the discharge of nutrients from the<br />

ornithogenic soils in the west coast of the region favors the<br />

increase of the primary production and in consequence of<br />

the zooplankton. Further studies will be nee<strong>de</strong>d to make<br />

possible the un<strong>de</strong>rstanding of the contribution of each one<br />

of those factors.<br />

Abstract: Assessment of faecal pollution indicators (total coliforms, Escherichia coli, Enterococcus sp., sulphite reducing clostridia<br />

and Clostridium perfringens) was carried out in water samples collected during the XXIX Brazilian Antarctic Expedition and<br />

sediment samples from the XXX Brazilian Antarctic Expedition. Wastewater at different stages in the sewage treatment plant<br />

were also analyzed for ammonia, total phosphorus, phosphates, chemical oxygen <strong>de</strong>mand (COD) and faecal indicators, in or<strong>de</strong>r<br />

to characterize the wastewater and evaluate the system performance. Water and sediment analysis showed low populations of<br />

faecal coliforms and the presence of the indicators in all sites, with higher frequencies and concentrations at EACF and Ullman<br />

Point sediment, indicating that a possible human impact is of low magnitu<strong>de</strong> and cannot be differentiated from interference caused<br />

by animal faeces. Assessment of the sewage treatment plant revealed that the wastewater produced at EACF has a typical faecal<br />

indicator composition and low contents of nutrients and COD, when compared to typical domestic sewage. Removal efficiency<br />

of COD was estimated in 20%, coliforms and enterococci removal varied from 84 to 98,7%, and no removal of nutrients was<br />

<strong>de</strong>tected, indicating that the treatment process can be optimized.<br />

Keywords: faecal pollution, microbial indicators, sewage treatment, E. coli, Clostridium sp., Enterococcus sp.<br />

Introduction<br />

Faecal pollution indicators are groups of microorganisms<br />

used to study the impact caused by sewage discharge.<br />

Faecal coliforms and Escherichia coli are the most common<br />

indicators used in these assessments, but they do not<br />

survive long periods un<strong>de</strong>r stress in the environment.<br />

For that reason, other indicator groups of bacteria can be<br />

used as an auxiliary analysis, such as sulphite reducing<br />

clostridia (especially Clostridium perfringens), a group<br />

of spore forming bacteria usually consi<strong>de</strong>red as a remote<br />

contamination indicator due to their longer persistence<br />

in the environment, and Enterococcus sp., which has been<br />

more frequently used as indicator in marine environments<br />

due to their higher resistance to salinity when compared to<br />

coliforms and E. coli (CETESB, 1978; Ferguson et al., 2005).<br />

Sewage treatment plants remove pollutants, nutrients and<br />

pathogenic microorganisms from wastewater through<br />

different stages: (1) preliminary, in which coarse solids are<br />

mechanically removed; (2) primary, which removes settable<br />

solids and part of the organic matter; (3) secon<strong>da</strong>ry, which<br />

consists biological removal of organic matter and eventually<br />

nutrients; (4) tertiary, aimed at removal of specific pollutants<br />

(toxic or non bio<strong>de</strong>gra<strong>da</strong>ble), complementary removal<br />

of nutrients and disinfection. Sewage treatment plants<br />

configuration varies according to the characteristics of the<br />

112 | Annual Activity Report 2011


wastewater and required quality of the effluent based usually<br />

in legislation (von Sperling, 2005). In EACF secon<strong>da</strong>ry<br />

and tertiary stages are present, with the use of aerobic and<br />

anaerobic digesters and a UV light disinfection system.<br />

In the present work, faecal pollution indicators were<br />

enumerated in sediment and water samples collected during<br />

Brazilian Antarctic Expeditions XXIX and XXX (BAE<br />

XXIX and BAR XXX). Wastewater samples at different<br />

stages of the EACF sewage treatment plant and soil in the<br />

effluent discharge area were also characterized for nutrients,<br />

chemical oxygen <strong>de</strong>mand and faecal indicators in or<strong>de</strong>r to<br />

obtain information on sewage properties and treatment<br />

efficiency.<br />

Materials and Methods<br />

Sampling and sample processing<br />

Samples were collected between December 2010 and March<br />

2011 (Brazilian Antarctic Expedition XXIX) and December<br />

2011 to February 2012 (Brazilian Antarctic Expedition<br />

XXX), and consisted of: (1) Water, collected in five stations<br />

(Table 1) along the water column (surface, middle and<br />

1 m from the bottom, as <strong>de</strong>termined by an ecobathymeter<br />

Vexilar mod LPS-1) and analyzed for coliforms (BAE XXIX)<br />

and enterococci (BAE XXX); (2) Sediment, collected in<br />

four stations (Table 1) at the 30 m isobaths (BAE XXX)<br />

and analyzed for coliforms, enterococci and clostridia;<br />

(3) Wastewater, sampled before treatment (affluent), after<br />

secon<strong>da</strong>ry treatment and before disinfection (secon<strong>da</strong>ry<br />

treatment effluent) and after disinfection with UV (effluent),<br />

analyzed for nutrients, chemical oxygen <strong>de</strong>mand (COD),<br />

coliforms, enterococci and clostridia; and (4) Soil at the<br />

interti<strong>da</strong>l region in wastewater discharge area, analyzed<br />

for coliforms, enterococci and clostridia. All samples were<br />

stored at 4 °C until analysis, which took place in a maximum<br />

period of 24 hours after sampling.<br />

Faecal pollution indicators enumeration<br />

In BAE XXIX, coliforms and clostridia in water, wastewater<br />

and soil samples were enumerated by the Most Probable<br />

Number (MPN) technique (APHA, 2005) using Colilert®<br />

medium (IDEXX) for total coliforms and E.coli and DRCM<br />

(differential reinforced clostridial medium) for clostridia.<br />

Presence of C. perfringens in DCRM cultures was confirmed<br />

by growth in Litmus Milk.<br />

In BAE XXX, the membrane filtration technique<br />

(CETESB, 1978) was chosen to enumerate coliforms,<br />

enterococci and clostridia in water, sediment, wastewater<br />

and soil samples. The change was ma<strong>de</strong> in or<strong>de</strong>r to enhance<br />

sensitivity and precision, as larger volumes of samples can be<br />

analyzed by this method. Media and incubation conditions<br />

used for enumeration of coliforms and E.coli, enterococci<br />

and clostridia were, respectively: modified membranethermotolerant<br />

Escherichia coli Agar (Modified mTEC),<br />

incubated at 35 °C for 2 hours, followed by incubation at<br />

44.5 °C waterbath for 22-24 hours; membrane-Enterococcus<br />

Indoxyl-β-D-Glucosi<strong>de</strong> Agar (mEI), incubated at 41 °C for<br />

24 hours; and mCP agar, incubated at 45 o C for 24 hours.<br />

Nutrients and COD<br />

Analysis of ammonia, total phosphorus, phosphates and<br />

chemical oxygen <strong>de</strong>mand in wastewater samples were<br />

carried out using reagent kits and photometer from Hanna<br />

Instruments, Inc. from aliquots of wastewater affluent and<br />

effluent before and after disinfection with UV, diluted to<br />

factors of 1:10 and 1:20 when necessary.<br />

Results<br />

Water, sediment and soil samples<br />

Water samples were analyzed for coliforms in BAE XXIX<br />

and for enterococci in BAE XXX (Figure 1). Analysis of<br />

coliforms, enterococci and clostridia in sediment at the 30 m<br />

isobaths were carried out in BAE XXX (Figure 2). Results<br />

of soil samples analysis in BAE XXIX showed E.coli and<br />

C. perfringens counts of 1.6 × 10 9 and 7.0 × 10 3 NMP/100 mL,<br />

respectively. In BAE XXX counts of E.coli, E. faecalis and C.<br />

perfringens were 1.0 × 10 6 , 1.0 × 10 6 , and 3.2 × 10 4 UFC/mL,<br />

respectively.<br />

Wastewater samples<br />

During BAE XXIX, analysis of sewage before treatment was<br />

carried out once (January 2011) and showed total coliforms<br />

and E.coli counts of 1.7 × 10 7 and 7.9 × 10 6 NMP/100 mL<br />

and sulphite reducing clostridia and C. perfringens counts of<br />

1.7 × 10 5 and 1.1 × 10 3 NMP/100 mL, respectively. Analyses<br />

of wastewater at outfall pipe were carried out four times and<br />

results can be seen in Figure 3. During BAE XXX, faecal<br />

indicators and physical chemical analysis of wastewater<br />

were performed at different stages at the treatment system<br />

(Table 2 and Figure 3), and removal efficiencies calculated<br />

for microbial indicators and COD (Table 2).<br />

Discussion<br />

As observed in previous work, low concentrations and<br />

wi<strong>de</strong>spread distribution of faecal indicators were <strong>de</strong>tected<br />

in Admiralty Bay (Figures 1 and 2). In sediment samples,<br />

higher values were found in EACF and Ullman Point sites, a<br />

pattern also observed in previous analysis (Nakayama et al.,<br />

2010). In water samples, EACF site was the only one to<br />

microbial indicators in bottom water samples may be<br />

related to regional hydrodynamics but can also suggest some<br />

for long time of indicators as coliforms and enterococci<br />

are not expected un<strong>de</strong>r adverse environmental conditions,<br />

Pote et al. (2009) observed that these groups of bacteria were<br />

able to maintain viability for at least 60 <strong>da</strong>ys in microcosms<br />

Figure 3. Most probable number and membrane filtering counts of faecal pollution indicators in wastewater samples at outfall pipe. BAE: Brazilian Antarctic<br />

Expedition.<br />

containing sediment, water and sewage treatment plant<br />

effluent incubated at 10 °C. However the presence of<br />

indicators in the water and sediment samples studied can be<br />

<strong>de</strong>rived not only from human but also from animal faeces.<br />

For instance, Lisle et al. (2004) confirmed the presence<br />

of C. perfringens in Wed<strong>de</strong>l Sea scats and Wright et al.<br />

(2009) <strong>de</strong>tected an average of 3.3 × 10 5 CFU/g enterococci<br />

in birds of a study recreational beach in Flori<strong>da</strong>, USA. All<br />

this consi<strong>de</strong>red, the a<strong>da</strong>ptation of molecular techniques for<br />

the <strong>de</strong>tection of faecal contamination in Antarctic samples<br />

seems to be an alternative to be consi<strong>de</strong>red for future studies.<br />

Some examples inclu<strong>de</strong> the use of PCR and qPCR techniques<br />

with genes related to coliform and enterococci groups as<br />

<strong>de</strong>scribed by Bej et al. (1990) and Colford et al. (2012).<br />

Even though the change in enumeration methods<br />

between BAEs XXIX and XXX may affect <strong>da</strong>ta comparisons,<br />

results of the analysis of the affluent wastewater did not show<br />

great differences during and between expeditions (Table 2).<br />

The populations of faecal indicators reflect the composition<br />

of the sewage produced in EACF, which is coherent to<br />

composition of domestic wastewater in general, with higher<br />

counts of coliforms and enterococci followed by clostridia<br />

(Leclerc et al., 1977). Counts at the effluent of the sewage<br />

treatment plant were more variable (Table 2 and Figure 3),<br />

as expected, once they are related to the flow of sewage<br />

produced in the station. The highest counts of coliforms<br />

(1,6 × 10 9 and 9,2 × 10 8 NMP/100 mL) were actually<br />

observed on 9 January 2011, when there were 150 people<br />

in the station, about twice the regular population at EACF.<br />

Sewage secon<strong>da</strong>ry treatment is usually responsible for 60<br />

to 99% coliforms removal (von Sperling, 2005). However,<br />

removal efficiencies calculated for the EACF plant (Table 2)<br />

showed that although the secon<strong>da</strong>ry treatment led to<br />

reduction of Enterococcus sp. populations (61,05 to 91,50%),<br />

no coliform removal occurred. Clostridia is a spore forming<br />

group of bacteria, which may explain the low removal values<br />

of about 30% observed in some analysis. The introduction<br />

of a tertiary treatment, represented by UV disinfection<br />

was <strong>de</strong>terminant for removal of microorganisms from<br />

the effluent, especially the coliforms, but high amounts of<br />

116 | Annual Activity Report 2011


microorganisms are still discharged and can be <strong>de</strong>tected<br />

in the soil near the sewage treatment plant outfall in<br />

concentrations in the or<strong>de</strong>r of 10 4 to 10 6 CFU/100 g. For<br />

that reason, improvements in the system should be ma<strong>de</strong><br />

to enhance removal of microorganisms from the effluent.<br />

Determination of nutrients and COD in effluent wastewater<br />

(Table 2) showed lower ammonia, total phosphorus and<br />

COD values than expected for regular domestic wastes<br />

(von Sperling, 2005). However, nutrient concentrations<br />

increased along wastewater treatment stages and COD<br />

removal efficiency was only 20.17%. Despite being<br />

preliminary <strong>da</strong>ta (<strong>de</strong>terminations were carried out in only<br />

one sample), values obtained indicate that the process<br />

could be optimized to perform more efficiently. Enhancing<br />

treatment performance would also contribute to increase<br />

inactivation rates of microbial contaminants by the UV<br />

disinfection system, since the presence of suspen<strong>de</strong>d solids,<br />

chemical oxygen <strong>de</strong>mand, color and organic compounds<br />

protect microorganisms by absorbing / scattering the UV<br />

light (Bitton, 1994).<br />

Conclusions<br />

Enumeration of faecal indicators in sediment and water<br />

samples revealed low populations with wi<strong>de</strong>spread<br />

distribution, as observed in previous work, indicating that<br />

influence of animal faeces cannot be discar<strong>de</strong>d and for that<br />

reason impact of human activities in the studied area is not<br />

unequivocally <strong>de</strong>tected. A first assessment of the EACF<br />

sewage treatment plant revealed that sewage produced in the<br />

research station has faecal indicators’ <strong>de</strong>nsities compatible<br />

to domestic sewages but lower contents of nutrients and<br />

organic matter (as indicated by chemical oxygen <strong>de</strong>mand)<br />

than typical domestic wastewater. According to preliminary<br />

<strong>da</strong>ta generated in the present work, the treatment plant<br />

removed about 20% COD, but no nutrient removal was<br />

observed. Removal efficiency of coliforms and enterococci<br />

varied from 84 to 98,7% after UV light disinfection, but<br />

discharged effluent still contained up to 10 6 indicators<br />

CFU/100 mL and 10 4 to 10 6 CFU/100 g were <strong>de</strong>tected in<br />

soil samples near the discharge area. Although impact of<br />

wastewater discharge seems to remain restricted to the<br />

area of discharge, optimization of the process is <strong>de</strong>sirable<br />

to attend to environmental protection goals for Antarctic<br />

ecosystems.<br />

Abstract: Sterols, n-alkanols and phytol were analyzed in three sediment cores collected in different regions of Admiralty Bay<br />

(Barrel Point, Refúgio II and Ferraz). The concentrations of total sterols ranged from 0.91 to 13.99 µg.g –1 , total n-alkanol from<br />

0.20 to 2.14 µg.g –1 and phytol from 0.13 to 2.38 µg.g –1 . Cholesterol was the most abun<strong>da</strong>nt sterol in the three cores, while the<br />

short-chain n-alkanols were the predominant n-alkanols. Phytol showed relatively low concentrations in all cores. These results<br />

indicate marine sources as responsible for the more dominant input of sedimentary organic matter with lower contributions from<br />

terrestrial sources. The vertical distribution of the organic markers analyzed was similar, with higher concentrations found at the<br />

top layers of all cores and the lower concentrations in the <strong>de</strong>epest layers, with some variations occurring along the profile. These<br />

changes may be the result of natural events and temperature oscillation over the last century which may have altered the dynamics<br />

of the supply of organic matter of the sediments of Admiralty Bay.<br />

Keywords: organic matter, sterols, n-alkanols, Antarctic Peninsula<br />

Introduction<br />

Sterols and n-alkanols are organic markers present in the<br />

polar fraction of lipid extracts in marine sediments, being<br />

directly associated with primary production (Hudson et al.,<br />

2001). They are also essential to marine organisms, acting<br />

as key components of cell membranes and to the regulation<br />

of specific metabolic processes (Laureillard et al., 1997).<br />

These markers are used to distinguish terrestrial and marine<br />

sources of sedimentary organic matter through, generally,<br />

the number of carbon atoms present in the aliphatic<br />

chain, and i<strong>de</strong>ntify organisms that act as sources of these<br />

compounds (Volkman, 1986; Faux et al., 2011).<br />

The distribution of these compounds in sediment<br />

cores may be useful for the un<strong>de</strong>rstanding of the temporal<br />

and local environmental changes based on natural and<br />

anthropogenic events in the recent past. The aim of this<br />

work was to i<strong>de</strong>ntify variations in the input and the sources<br />

of sedimentary organic matter <strong>de</strong>posited in sediments<br />

from Admiralty Bay, through the <strong>de</strong>termination of organic<br />

markers, such as sterols and n-alkanols.<br />

Materials and Methods<br />

Study area<br />

The study area was <strong>de</strong>fined as Admiralty Bay (62° 02’ S and<br />

58° 21’ W), the largest fjord in the South Shetland Islands,<br />

located on King George Island (Figure 1), with total area<br />

of 120 km 2 . It is formed by a >500 m <strong>de</strong>ep main channel,<br />

that divi<strong>de</strong>s the bay in three main inlets (Martel, Mackelar<br />

and Ezcurra), and in each there is a research station. The<br />

presence of high diversity of marine organisms, plants<br />

and animals, such as, fungi, mosses, birds and mammals,<br />

represents the sources of different classes of biomarkers.<br />

Sampling<br />

The sampling was carried out during the austral summer of<br />

2006/2007 and 2009/2010, in three inlets around Admiralty<br />

Bay (Ferraz - FER, Barrel Point - BAR and Refúgio II – REF,<br />

Figure 1). The cores were obtained from a box core sampler,<br />

and sub-sampled into sections of 1 cm (except REF, where<br />

sections were 2 cm).<br />

Analytical procedure<br />

The analytical method used to analyze the sterols and<br />

n-alkanols in sediments was a<strong>da</strong>pted from UNEP (1992)<br />

with modification. Around 20 g of sediment were extracted<br />

using a Soxhlet system during 8h with 80 mL of n-hexane:<br />

dichloromethane (DCM) (1:1) (both J.T. Baker), and<br />

with 100 µL of a solution containing surrogates eicosene,<br />

hexa<strong>de</strong>cene (50 ng.µL –1 ) and 5α-androstanol (20 ng.µL –1 ).<br />

This extract was reduced to c. 2 mL by rotoevaporation<br />

and submitted to a clean up in column chromatography<br />

using 3.2 g of silica (silica gel 60, 0.063-0.200 mm, Merck)<br />

and 1.8 g of alumina (aluminum oxi<strong>de</strong> 90 active, 0.063-<br />

0.200 mm, Merck) (5% <strong>de</strong>activated). The samples were<br />

eluted with 10 mL of n-hexane to fraction 1 (aliphatic<br />

hydrocarbons – not analyzed), 15 mL of n-hexane/DCM<br />

30% to fraction 2 (PAHs +alkenones – not analyzed) and<br />

5 mL of ethanol/DCM 1:9, following 20 mL of ethanol<br />

to fraction 3 (sterols and n-alkanols). The fraction 3 was<br />

evaporated to dryness and <strong>de</strong>rivatized to form trimethylsilyl<br />

ethers using BSTFA (bis(trimethylsilyl)trifluoroacetami<strong>de</strong>)<br />

with 1% TMCS (trimethylchlorosilane) during 90 minutes<br />

at 65 °C. The mixture of TMS-sterols and n-alkanols<br />

<strong>de</strong>rivatives was <strong>de</strong>termined by the injection of 2 µL into<br />

a gas chromatograph equipped with a flame ionization<br />

<strong>de</strong>tector (GC-FID).<br />

Results<br />

Seventeen sterols were i<strong>de</strong>ntified, with total sterols<br />

concentration ranging from 0.91 to 2.17 µg.g –1 (BAR), from<br />

1.63 to 8.59 µg.g –1 (REF) and from 2.64 to 13.99 µg.g –1 (FER).<br />

The distribution of total sterols concentration according<br />

to the <strong>de</strong>pth for three cores can be visualized in Figure 2.<br />

Total sterols in BAR showed higher concentration<br />

between 7 and 11 cm, with lower concentrations in <strong>de</strong>eper<br />

layers. In REF, higher concentrations were found from 7 cm<br />

toward the surface while FER showed some variations over<br />

time, with lower concentrations observed between 7 and<br />

16 cm (Figure 2).<br />

Fourteen n-alkanols were i<strong>de</strong>ntified, with total n-alkanols<br />

concentration varies from 0.20 to 0.58 µg.g –1 (BAR), 0.33<br />

to 2.14 µg.g –1 (REF) and 0.22 to 1.97 µg.g –1 (FER). The<br />

distribution of total n-alkanols concentration in different<br />

layers for three cores is shown in Figure 3.<br />

Total n-alkanols en BAR was similar to the total sterols,<br />

with highest concentrations between 7 and 11 cm. In REF,<br />

the highest values of concentrations occurred between 7 and<br />

9 cm, while FER presented three concentrations peak at<br />

16.5, 6.5 and 0.5 cm.<br />

Phytol, an isoprenoid alcohol <strong>de</strong>rived from chlorophyll-a<br />

<strong>de</strong>gra<strong>da</strong>tion (Volkman et al., 2008), was found in all cores<br />

analyzed. The distribution of phytol concentration in<br />

different layers for three cores is shown in Figure 4.<br />

Phytol concentration varied from 0.17 to 0.26 µg.g –1<br />

(BAR), 0.13 to 2.39 µg.g –1 (REF) and 0.24 to 1.26 µg.g –1<br />

(FER). Relative low concentrations and close to the <strong>de</strong>tection<br />

limit were presented in the BAR, while REF and FER showed<br />

highest concentrations in top core sections, represented<br />

as the recent sediments. In the others sections, a regular<br />

distribution with no significant variations was observed.<br />

Discussion<br />

The variation observed along vertical profiles, for both<br />

sterols as n-alkanols, may reflect variations in the input<br />

of organic matter in the environment, besi<strong>de</strong>s the section<br />

with higher concentration indicating higher contributions<br />

of sedimentary material, while sections with <strong>de</strong>creased<br />

values indicate a low input or organic matter reduction on<br />

sediments (Meyers, 1997). These variations may occur due<br />

to environmental changes, which have an influence on the<br />

organic matter processes related with the input, burial and<br />

preservation and/or <strong>de</strong>gra<strong>da</strong>tion (Faux et al., 2011), or as the<br />

result of natural variability. The <strong>de</strong>creased concentrations<br />

with core <strong>de</strong>pth were not constant and may also be a result<br />

of diagenesis (Burns & Brinkman, 2011).<br />

Cholesterol was the most abun<strong>da</strong>nt sterol. Several<br />

organisms that inhabit the region are potential sources<br />

of cholesterol, including seal, whales and phyto and<br />

zooplankton (Volkman, 2005). The <strong>de</strong>tectable concentration<br />

of 17 different sterols analyzed is an evi<strong>de</strong>nce of the large<br />

sources diversity of organic matter contributing to the<br />

sediment composition in Admiralty Bay. The presence of<br />

Figure 3. Vertical profile of total n-alkanols (in µg.g –1 ) in sediment cores from Admiralty Bay, Antarctic Peninsula.<br />

122 | Annual Activity Report 2011


Figure 4. Vertical profile of total phytol (in µg.g –1 ) over the cores in Admiralty Bay, Antarctic Peninsula.<br />

saturated sterols in sediments indicates the occurrence of<br />

diagenic process due to the fact that they are not commonly<br />

found with significant abun<strong>da</strong>nce in organisms (Hassett &<br />

Lee, 1977).<br />

The predominance of short-chain n-alkanols in all<br />

cores suggest the organic matter in this region is primarily<br />

associated with marine organisms, which inclu<strong>de</strong> sources<br />

like, aquatic algae and bacteria (Xiong et al., 2010),<br />

zooplankton (Burns & Brinkman, 2011) and hydrolysis<br />

of the wax esters of zooplankton which may increase the<br />

saturated and unsaturated C 14<br />

-C 22<br />

alcohols (Volkman, 2006).<br />

In Antarctic region, phytol contribution is related to<br />

vascular plants (D. Antarctica e C. quitensis), lichens,<br />

mosses and algae (Wang et al., 2007). However, the low<br />

concentrations observed in all cores in this study compared<br />

to marine sediments from temperate/tropical areas may<br />

be related with the absence of significant sources for this<br />

compound in the region. Another explanation is to low<br />

phytol concentration is related to the <strong>de</strong>gra<strong>da</strong>tion compound<br />

in sediments, which inclu<strong>de</strong>s aerobic and anaerobic<br />

bio<strong>de</strong>gra<strong>da</strong>tion, photo <strong>de</strong>gra<strong>da</strong>tion and sulphurization in<br />

sediment-water interface.<br />

Conclusions<br />

Based on the results, a multiplicity of sources of marine<br />

organic matter from sediments from Admiralty Bay could<br />

be verified, mainly associated with marine origin, with<br />

little contribution from terrestrial material. Despite of the<br />

transformation processes of organic matter, the compounds<br />

showed relative preservation, representing the variations<br />

and distribution of organic matter along the vertical profiles.<br />

This study is a first insight about polar organic markers<br />

in sediment cores of Admiralty Bay and the results, after<br />

more <strong>de</strong>eper interpretation and including other proxies<br />

(e. hydrocarbons, elemental and isotopic analyses) may<br />

contribute to a better un<strong>de</strong>rstanding of the processes related<br />

to organic matter contribution and the changes as a result<br />

of natural events and temperature oscillation over the last<br />

century.<br />

Abstract: Fecal sterols (coprostanol and epicoprostanol) and linear alkylbenzenes (LABs) are efficient geochemical markers<br />

of sewage input in marine environment because they present stability and resistance to <strong>de</strong>gra<strong>da</strong>tion processes. The Antarctic<br />

region is consi<strong>de</strong>red one of the best preserved environments in the world, however the discharge of sewage directly into the<br />

marine environments around scientific stations has resulted in changes in this pristine site. In or<strong>de</strong>r to assess the distribution<br />

and concentration of sewage indicators from Coman<strong>da</strong>nte Ferraz Brazilian Antarctic Station, sediments were sampled during<br />

the 2009/10 austral summer at four points: (1) Refuge II (Mackelar Inlet), (2) Ferraz, (3) Ulmann and (4) Botany Point (Martel<br />

Inlet) at <strong>de</strong>pths around of 20 until 30 m. The organic markers were <strong>de</strong>termined by gas chromatography with flame ionization<br />

(GC-FID) and mass spectrometer <strong>de</strong>tectors (GC-MS). Concentrations of fecal sterols and LABs ranged from


treatment procedures that clean their effluent. However, the<br />

(un)treated sewage containing domestic waste is discharged<br />

directly into the marine environment and these discharges<br />

should be monitored to <strong>de</strong>scribe the extent of sewage<br />

contaminantion from Antarctic stations.<br />

The aim of this report is to evaluate the sewage<br />

contribution from Ferraz station into Admiralty Bay<br />

and to compare the historical trend reported in previous<br />

studies. This evaluation is based on the results of sewage<br />

geochemical indicators from the upper layer of sediments<br />

sampled during the austral summer of 2009/10 and<br />

previous results (1997-2004). In Antarctica, monitoring<br />

the extent of sewage input dispersal is essential as Antarctic<br />

Treaty signatory nations must conform to the Protocol on<br />

Environmental Protection.<br />

Materials and Methods<br />

Study area<br />

The study area is the Martel Inlet, in Admiralty Bay, King<br />

George Island located in the South Shetland Islands,<br />

Antarctic Peninsula (62° 02’ S and 58° 21’ W) (Figure 1).<br />

Admiralty Bay has an area of 131 km², reaches <strong>de</strong>pths<br />

of up to 530 m and has a coastline with many bays<br />

(Santos et al., 2007), being the largest bay of King George<br />

Island, one of the South Shetlands Islands. There are three<br />

large inlets in Admiralty Bay: Martel, Mackelar and Ezcurra<br />

and each of them holds a research station. The Mackelar and<br />

Martel Inlets constitute the North part of the Bay while the<br />

Ezcurra Inlet is in the West.<br />

Sampling<br />

Sediment was obtained from a box core sampler<br />

(25 × 25 × 55 cm) during the austral summer of 2009/10 at<br />

four points: (1) Refuge II (REF) (Mackelar Inlet); (2) Ferraz<br />

(FER); (3) Ulmann (ULM), and; (4) Botany Point (BTP)<br />

(Martel Inlet) (Figure 1), at <strong>de</strong>pths around of 20 until 30<br />

m. The upper sediment layers (first 2 cm) were used for<br />

organic markers analyses.<br />

Analytical procedure<br />

The analytical method used for the analysis of sterols in<br />

sediments is <strong>de</strong>scribed in Kawakami & Montone (2002).<br />

Around 20 g of sediment from each site were extracted<br />

using a Soxhlet system for 8 h with 70 mL of ethanol. The<br />

ethanol extract was reduced to c. 2 mL by rotoevaporation<br />

and submitted to a clean up with column chromatography<br />

using 2 g of 5% <strong>de</strong>activated alumina and elution with<br />

15 mL of ethanol. The extracts were evaporated to dryness<br />

and <strong>de</strong>rivatized to form trimethylsilyl ethers using BSTFA<br />

(bis(trimethylsilyl)trifluoroacetami<strong>de</strong>) with 1% TMCS<br />

(trimethylchlorosilane) for 90 minutes at 65 °C. The mixture<br />

of TMS-sterols <strong>de</strong>rivatives was <strong>de</strong>termined by the injection<br />

of 2 µL into a gas chromatograph equipped with a flame<br />

ionization <strong>de</strong>tector (GC-FID).<br />

The procedure for analyses of LABs is based on UNEP<br />

(1992). About 25 g of dry sediment samples were Soxhletextracted<br />

with hexanes/dichloromethane (1:1) for an<br />

8-hour period. The solvent extract was concentrated<br />

in a rotary evaporator to a volume of approximately<br />

2 mL. The extract was fractionated by adsorption liquid<br />

chromatography into aliphatic and aromatic hydrocarbons<br />

using a column of alumina and silica gel, and hexanes and<br />

30% dichloromethane/hexanes for aliphatic and LABs (F1)<br />

and aromatic (F2) fractions as eluent, respectively. The<br />

fractions were concentrated again in a rotary evaporator,<br />

transferred to a vial, and then the volume was adjusted to<br />

1 mL exactly using a stream of N 2<br />

gas. Instrumental <strong>de</strong>tails<br />

for both analyses are <strong>de</strong>scribed by Montone et al. (2010).<br />

Results<br />

Concentrations of fecal sterols and total concentration of<br />

linear alkylbenzenes (total LABs) containing alkyl chains<br />

ranging from 10 to 14 carbon atoms in the superficial<br />

sediments at Admiralty Bay are shown in Table 1.<br />

Discussion<br />

The values for fecal sterol (coprostanol + epicoprostanol)<br />

ranged from not <strong>de</strong>tected (


Figure 2. Fecal sterols in marine sediments in the vicinity of the EACF (10-20 m <strong>de</strong>pth) in the austral summer from 1997/98 to 2009/10. The line at 0.19 μg g −1<br />

suggests the background value for Martel Inlet.<br />

concentrations of fecal sterols in sediments near the Ferraz<br />

outfall (10-20 m <strong>de</strong>pth) were plotted together, as shown in<br />

Figure 2.<br />

The sewage contribution gradually increases until<br />

2003/04 as a result of the human population doubling at<br />

Ferraz Station over time. However, after this period, the<br />

concentrations <strong>de</strong>clined as result of some a<strong>da</strong>ptation to the<br />

sewage outfall used to discharge the treated waste water. The<br />

sewage contribution to Admiralty Bay is still un<strong>de</strong>r control<br />

because of local hydrodynamic conditions, especially due<br />

to ti<strong>da</strong>l effects, which have favored the dispersion of the<br />

sewage effluent in the shallow coastal zone at Martel Inlet<br />

and the levels found in this study are lower than suggested by<br />

Gonzalez-Oreja & Saiz-Salinas (1998) as indicator of sewage<br />

contamination (>0.50 μg g −1 ). The maximum concentration<br />

to fecal sterols (0.17 μg g −1 ) is close to the value previously<br />

calculated as background level to Martel Inlet (0.19) what<br />

confirms the statement above.<br />

Total LABs were found only at sites close to Ferraz Station<br />

(FER-A and FER-B) and it was around 42.5 and 46.5 ng g –1 .<br />

Further, total LABs found at sites in the current study, in<br />

general, are very low compared to levels at Davis Station<br />

(510 ng g −1 ) (Green & Nichols, 1995). However, the levels<br />

are similar or slightly higher compared to a previous studies<br />

released at Admiralty Bay (12 ng g −1 – Martins et al., 2002;<br />

35 ng.g -1 – Montone et al., 2010).<br />

In general, higher concentrations of LABs with 11 up to<br />

13 carbon atoms were observed, being coinci<strong>de</strong>nt with the<br />

main mixture of Cm-LABs (m = 10 – 14) used in Brazil,<br />

with the percentage of each isomer group as follows: 5-16%<br />

(C 10<br />

-LABs), 28-45% (C 11<br />

-LABs), 25-30% (C 12<br />

-LABs), 10-<br />

30% (C 13<br />

-LABs) and

Abstract: Sequential extraction, based on the method <strong>de</strong>veloped by the European Community Bureau of Reference, was performed<br />

to <strong>de</strong>termine the mobile fractions of trace elements in sediments from Admiralty Bay, Antarctica. Except for As that is not certified,<br />

the quality of the <strong>da</strong>ta was found to be satisfactory for analysis as certified reference material, BCR-701, with recovery values for Cu,<br />

Ni, Pb and Zn, ranging from 90-115%. Zn and Ni were mainly found in the residual fraction, reflecting their natural contribution<br />

in the bay. As, Cu and Pb exhibited high potential mobility, above 60%, for most of the samples. Despite Pb contents being found<br />

mainly in the extractable fraction, its concentrations (ranging from 4.5 to 8.3 mg kg –1 ) were well below the Threshold Effect Levels.<br />

In general, As and Cu mobile contents were higher than the sediment quality values, according to the Canadian Environmental<br />

Gui<strong>de</strong>lines, which indicates that adverse biological effects to aquatic organisms can occur. However, since disturbances in Admiralty<br />

Bay are seldom observed, it can be inferred that As and Cu are preferably bound to the organic matter. Otherwise, this study<br />

presents the <strong>da</strong>ta set regarding sediments collected before the acci<strong>de</strong>nt that happened in Ferraz Station in February of 2012. That<br />

singular event may have caused a relevant increase of available contents of the trace elements in the local aquatic system. Thus,<br />

valuable information is being provi<strong>de</strong>d for the future environmental monitoring, control and mitigation of arsenic and metal<br />

contamination in sediments from Antarctica.<br />

Keywords: Antarctic sediments, arsenic, metals, sequential extraction method<br />

Introduction<br />

Anthropogenic trace-element contamination in aquatic<br />

systems can affect the diversity of benthic organisms<br />

(Stark et al., 2003). The intake body of contaminant inclu<strong>de</strong>s<br />

three different paths, such as pore water intake or, only,<br />

sediment intake (Simpson et al., 2005).<br />

According to Sun<strong>da</strong>ray et al. (2011), there is no<br />

correlation between the total concentration and the<br />

elemental toxicity. Otherwise, the chemical form and<br />

mobility are the principal parameters to assess the elemental<br />

toxicity in the environment. Hence, the ability to i<strong>de</strong>ntify<br />

the chemical forms of elements in marine and freshwater<br />

sediments is very important to environmental monitoring<br />

studies.<br />

Thereafter, sequential extraction techniques have been<br />

used as an alternative to evaluate the history of elemental<br />

input, digenetic transformation within the sediments and<br />

the reactivity of trace-element species of both natural and<br />

anthropogenic sources (Passos et al., 2010; Sun<strong>da</strong>ray et al.,<br />

2011).<br />

Despite the importance of the Antarctic Continent<br />

to local and global environmental changes, the scientific<br />

studies regarding mobility of metals in sediments are<br />

130 | Annual Activity Report 2011


still scarce (Cosma et al., 1994; Dalla Riva et al., 2004;<br />

Ianni et al., 2010). In fact, literature concerning Antarctic<br />

marine sediments focus mostly on total metal content<br />

(Negri et al., 2006; Santos et al., 2007), pseudo total content,<br />

using a mixture of strong acids, such as aqua regia (1 HNO 3<br />

:<br />

3 HCl v/v), or on extractable content by dilute acid, in most<br />

cases to HCl (Cosma et al., 1994; Dalla Riva et al., 2004)<br />

The aim of this work is to contribute to the knowledge<br />

on Antarctic geochemistry regarding metals (Cu, Ni, Pb and<br />

Zn) and arsenic availability to interact to benthic organism<br />

in the aquatic systems. Thus, a sequential extraction was<br />

performed according to the procedure recommen<strong>de</strong>d by<br />

the Stan<strong>da</strong>rds, Measurements and Testing programme of<br />

the European Union, SM& T, so-called BCR, (Pueyo et al.,<br />

2001) in sediments from four sampling sites in Admiralty<br />

Bay, Antarctica.<br />

Materials and Methods<br />

Sampling<br />

Eight short sediment cores, with <strong>de</strong>pth of 10 cm, were<br />

collected in Admiralty Bay, along the Martel (sampling<br />

sites: Ferraz, Botany Point and Ullman Point) and Mackellar<br />

Inlets (sampling site: Refúgio) during the 28 th Brazilian<br />

Antarctic Expedition in the 2009/2010 austral summer.<br />

To obtain undisturbed samples, the cores were sliced in<br />

0-2, 2-6 and 6-10 cm, using a stainless steel spatula, and<br />

the sediment samples were freeze-dried, further, they were<br />

carefully homogenized in mortar and stored in polyethylene<br />

bags until chemical analysis at LaQIMar (Marine Inorganic<br />

Chemistry Laboratory), located at the Oceanographic<br />

Institute of the University of São Paulo (Brazil).<br />

Analytical procedures<br />

Inductively coupled plasma atomic emission spectrometer<br />

(ICP OES) was the analytical technique used to measure<br />

the levels of arsenic and metals in the sediment samples.<br />

The methodology for <strong>de</strong>termining the fractionation of<br />

trace elements was the three step protocol proposed by the<br />

Stan<strong>da</strong>rds, Measurements and Testing programme (SM &<br />

T, formerly BCR) of the European Community Bureau of<br />

Reference . BCR procedure consists of the following stages,<br />

respectively: STEP 1 (S1) – exchangeable and bound to<br />

carbonate (acid-labile fraction); STEP 2 (S2) – bound to<br />

Fe and Mn oxi<strong>de</strong>s and hydroxi<strong>de</strong>s (reducible fraction);<br />

STEP 3 (S3) – bound to organic and matter sulphi<strong>de</strong>s<br />

(oxidizable fraction). The content of residual stage (STEP<br />

4 – S4) was obtained from the difference between the total<br />

concentration of the elements, which was obtained by aqua<br />

regia digestion and the sum of stages 1, 2 and 3. Pueyo et al.<br />

(2001) <strong>de</strong>scribe the <strong>de</strong>tails of the BCR procedure.<br />

Results<br />

Except for As that is not certified, accuracy of the method<br />

was checked by analysis of six replicates of certified sediment<br />

reference material (BCR-701, European Community Bureau<br />

of Reference). For each extraction step, the experimental<br />

concentration of each metal was compared with the<br />

reference value, and the recovery calculated as the ratio (%)<br />

between measured and certified values. The quality <strong>da</strong>ta<br />

was found to be satisfactory with recovery values for Cu,<br />

Ni, Pb and Zn ranging from 93-113%, 109-113%, 93-111%<br />

and 90-115%, respectively.<br />

Figures 1 and 2 show the mobile fractions (%) and the<br />

concentrations (mg kg –1 ) for the sum of the steps (∑ S1; S2;<br />

S3). The elements presented the same behavior, i.e. their<br />

mobile fractions were in same or<strong>de</strong>r of magnitu<strong>de</strong>, in each<br />

sampling site. Therefore, only the results for Ferraz and<br />

Refúgio are shown (Figures 1 and 2).<br />

Ni and Zn extraction were constant (their mobile levels,<br />

for the most sediment samples, were lower than 70 and 40%,<br />

respectively). The mobile fraction of As was higher than<br />

70% and Cu was above 60%. The highest Pb total content<br />

was 8.3 mg kg –1 .<br />

Discussion<br />

According to the Canadian Sediment Quality Gui<strong>de</strong>lines<br />

(CCME, 1999), Zn total contents were well lower than the<br />

Threshold Effect Levels (TEL), indicating its lithogenic<br />

origins and limited potential bioavailabilities.<br />

The Canadian gui<strong>de</strong>lines suggest two sediment<br />

Conclusions<br />

Since there have been no relevant disturbances in the<br />

Antarctic environment until February of 2012, As and Cu<br />

mobilities to the local aquatic system could be suggested as<br />

negligible. Unfortunatly, the tragic event in Ferraz Station<br />

may have caused a significant antropoghenic input of<br />

chemical compounds into Admiralty Bay. Accordingly, the<br />

present study will provi<strong>de</strong> substantial information to the<br />

future recovery works in the Antarctic landscape.<br />

Abstract: The bioaccumulation of trace elements is <strong>de</strong>fined as the uptake of a chemical by an organism from the abiotic and/or<br />

biotic (food) environment, and is a wi<strong>de</strong>ly observed and very important process consi<strong>de</strong>ring the impact assessment of anthropogenic<br />

activities. In Antarctica the main local source of metal and metalloid is related to the activities of research stations. In or<strong>de</strong>r to<br />

verify the contribution of the Coman<strong>da</strong>nte Ferraz Brazilian Antarctica Station (EACF- Portuguese acronym, in continuity) in<br />

the accumulation of these elements, and to supply baseline values to allow future monitoring, the concentration of Ag, As, Cd,<br />

Cu, Ni, Pb and Zn was measured in twelve benthic Antarctic species (Desmarestia sp, Himantothallus grandifolius, Laternula<br />

elliptica, Yoldia eightsi, Amphioplus acutus, Bovalia gigantea, Gondogeneia antarctica, Sterechinus neumayeri, Nacella concinna,<br />

Paraserolis polita, Parborlasia corrugatus and Glyptonotus antarcticus). A wi<strong>de</strong> variation in metal content was observed <strong>de</strong>pending<br />

on the species and the element. These concentrations were usually lower than those of other Antarctic areas, not indicating<br />

relevant anthropogenic impacts of EACF. However, consi<strong>de</strong>ring the serious fire inci<strong>de</strong>nt that occurred at the end of last summer<br />

(February/2012), and that relevant measures of heavy metals (such as Pb, Cd, and Zn) are released in this kind of event, this <strong>da</strong>ta,<br />

and the associated methodology, attains particular importance, due to their potential to enlighten the extension of this impact, as<br />

well as, the success of any recuperation strategy.<br />

Keywords: Antarctica, bioaccumulation, metal, metalloid<br />

Introduction<br />

The bioaccumulation of trace elements is <strong>de</strong>fined as the<br />

uptake of a chemical by an organism from the abiotic and/<br />

or biotic (food) environment (Gray, 2002), and is a wi<strong>de</strong>ly<br />

observed process (e.g. Santos et al., 2006; Farías et al.,<br />

2007; Gray et al., 2008; Grotti et al., 2008). For metals<br />

and metalloids the bioaccumulation may be the result of<br />

natural sources, since these elements are constituents of<br />

any ecosystem (Grotti et al., 2008). In Antarctica, like other<br />

remote regions of the Earth, the natural concentration of<br />

metals and metalloids in abiotic matrices (snow, ice, soil,<br />

sediment and air) of most areas are generally within or<br />

lower than the observed values of other polar areas, being<br />

consi<strong>de</strong>red as background levels (Sanchez-Hernan<strong>de</strong>z,<br />

2000). However, near the research stations a lower but<br />

continuous kind of contamination is observed (Vodopivez<br />

& Curtosi, 1998), directly linked with activities such as<br />

garbage incineration, use of paints, fuel usage and sewage<br />

(Santos et al., 2004). The result is an increased concentration<br />

of both organic and inorganic contaminants, and their<br />

impacts are obviously linked with the increasing presence<br />

of humans (Bargagli et al., 1998). In or<strong>de</strong>r to monitor the<br />

effects of the activities in the surrounding biota, the potential<br />

bioaccumulation of a variety of metals and metalloids<br />

(Ag, As, Cd, Cu, Ni, Pb and Zn) was verified for different<br />

Antarctic organisms sampled near EACF.<br />

Methodology<br />

Twelve benthic Antarctic species (macroalgae –<br />

Desmarestia sp, Himantothallus grandifolius, bivalves<br />

– Laternula elliptica and Yoldia eightsi, ophiuroid –<br />

Amphioplus acutus, amphipods – Bovalia gigantea and<br />

Gondogeneia antarctica, sea urchin – Sterechinus neumayeri,<br />

limpet – Nacella concinna, isopods - Paraserolis polita and<br />

Glyptonotus antarticus, nemertean - Parborlasia corrugatus)<br />

were sampled nearby EACF, located in Admiralty Bay,<br />

the largest bay of King George Island. Samples of benthic<br />

invertebrates and macroalgae were obtained manually in<br />

the interti<strong>da</strong>l zone, and between <strong>de</strong>pths of 10-20 m onboard<br />

the R/B SKUA, using a van Veen grab, a dredge or by Scuba<br />

diving, from November/2005 to February/2006, during the<br />

austral summer of the 24 th Brazilian Antarctic Expedition.<br />

Methods followed those of a previous study performed by<br />

Corbisier et al. (2004).<br />

Silver (Ag), arsenic (As), cadmium (Cd), copper (Cu),<br />

nickel (Ni), lead (Pb) and zinc (Zn) concentrations on<br />

the organisms were obtained by the analytical technique<br />

of Inductively Coupled Plasma – Optical Emission<br />

Spectrometry (ICP OES). For that, 0.35 g of each dried<br />

sample was digested with 4 mL of nitric acid, to which, six<br />

hours later, was ad<strong>de</strong>d 1 mL of hydrogen peroxi<strong>de</strong>. After<br />

18 hours it was disposed in a heating block digester for<br />

3 hours, and the final solution was filtered and diluted to<br />

the final volume of 30 mL. The expressed concentrations<br />

of elements in the samples represent the mean of three<br />

in<strong>de</strong>pen<strong>de</strong>nt <strong>de</strong>terminations. Certified Reference Materials<br />

(CRM - Mussel Tissue – NIST-SRM2976) were analyzed in<br />

parallel with the trace element <strong>de</strong>terminations, and reagent<br />

blanks were run with all sample analyses.<br />

Results<br />

The metal and metalloid concentrations for the several<br />

investigated species are summarized in Table 1. The species<br />

with the highest metal or metalloid concentration varied<br />

according to the analyzed element. The grazer S. neumayeri<br />

showed the highest concentration for Zn (353.91 µg g –1 ).<br />

High concentrations of Cu were observed for the carnivores<br />

G. antarticus and P. polita (126.18 and 115.71 µg g –1<br />

respectively). The suspension fee<strong>de</strong>r L. elliptica showed<br />

the highest values for Ag and As (1.04 and 45.88 µg g –1 ,<br />

respectively), while for Cd, Ni and Pb the highest values<br />

were observed for the carnivore P. corrugatus (5.02 µg g –1 ),<br />

for the macroalgae Desmarestia sp (16.66 µg g –1 ), and for<br />

the ophiuroid A. acutus (9.31 µg g –1 ), respectively.<br />

Discussion<br />

Different factors can affect metal bioaccumulation in<br />

organisms, such as its environmental bioavailability (Gray,<br />

2002), but also the assimilation efficiency and efflux<br />

rate of the studied species (Wang & Ke, 2002). All these<br />

factors contribute to the variability of the results, however,<br />

comparing the concentration for each species with those<br />

in the literature, which for some species is scarce, lower<br />

or similar values were observed in our sampling point<br />

(Admiralty Bay) than for other Antarctic areas. For instance,<br />

the As concentration for H. grandifolius in Admiralty Bay<br />

was only 13% (112 µg g –1 ) of those observed by Farías et al.<br />

(2002) for samples from the Argentinian base at Potter<br />

Cove (King George Island), and 16% (91 µg g –1 ) for those<br />

obtained by Runcie & Riddle (2004) for Casey Station, East<br />

Antarctica. The same pattern was observed when comparing<br />

Cd concentration for S. neumayeri and P. corrugatus from<br />

Terra Nova Bay (Ross Sea–Northern Victoria Land), with<br />

our estimates being only 14 and 23%, respectively, of those<br />

observed by Dalla Riva et al. (2004). Only for Zn, and in<br />

this case in a closer sampling point (in front of EACF), our<br />

concentrations were slightly smaller than those observed<br />

by Santos et al. (2006) for B. gigantea, G. antarctica and<br />

N. concinna. These results agree with those obtained<br />

through sediment analysis for EACF, in which, <strong>de</strong>spite being<br />

observed an enrichment of As, there were no indications<br />

of relevant anthropogenic impacts (Ribeiro et al., 2011).<br />

Conclusions<br />

These results contribute to the knowledge of the possible<br />

impacts of the Coman<strong>da</strong>nte Ferraz Brazilian Antarctica<br />

Station consi<strong>de</strong>ring the liberation of metal and metalloids<br />

due to their routine activities. The temporal comparisons<br />

between this <strong>da</strong>ta and those of other monitoring<br />

samplings (previous and posterior to 2005/2006) will allow<br />

i<strong>de</strong>ntification of any increment in terms of bioaccumulation<br />

in the surrounding biota. Especially, consi<strong>de</strong>ring the serious<br />

fire inci<strong>de</strong>nt that occurred at EACF at the end of last summer<br />

(Feb/2012), and that relevant amounts of heavy metals (such<br />

as Pb, Cd, Fe, Mo, and Zn) are released during this kind of<br />

occurrence, this <strong>da</strong>ta, and the associate methodology, attains<br />

particular importance, due to their potential to enlighten<br />

the extension of the impacts, as well as, the success of any<br />

recuperation strategy.<br />

Abstract: The Antarctic continent is consi<strong>de</strong>red one of the most well preserved areas of the planet; however, human occupation of<br />

this environment, for research purposes, generates impacts on the ecosystem, especially near scientific stations. Studies on structural<br />

alterations, mainly of the liver and gills of fish are an important source of information of environmental toxicity. This work inten<strong>de</strong>d<br />

to evaluate histopathologically, the livers and gills of the Antarctic fish species Notothenia coriiceps and Notothenia rossii captured<br />

in Admiralty Bay, where the Coman<strong>da</strong>nte Ferraz Brasilian Antarctica Station is located. Histological and ultrastructure techniques<br />

were employed. The only liver diseases found were necroses and hyperplasia, aneurysm and branchial <strong>de</strong>tachment were the diseases<br />

found on the gills. The occurrence of alterations, both in the liver and gills, was low and punctual, although with higher inci<strong>de</strong>nce<br />

in the N. coriiceps than N. rossii. It can be conclu<strong>de</strong>d that the low alteration occurrence rate, does not affect the functionality of<br />

the analyzed organs, as it presents no lethality to the species.<br />

Keywords: Antarctic nototeni<strong>da</strong>e, gills, liver, aquatic contamination<br />

Introduction<br />

Studies reporting human activity in the Admiralty Bay<br />

<strong>da</strong>te back to 1987, with the beginning of the analyzes of<br />

hydrocarbon concentrations in sediments and on the<br />

water surface (Bícego et al., 1996; Oliveira et al., 2007;<br />

Martins et al., 2010). The research about distribution<br />

and concentration patterns of waste indicators <strong>de</strong>riving<br />

from the station in soil samples (Montone et al., 2010),<br />

the biomonitoring of genotoxic potential through nuclear<br />

erythrocyte abnormalities (Ngan et al., 2007) and the<br />

evaluation of heavy metal concentration (Santos et al., 2006)<br />

are examples of well-studied cases.<br />

Histopathological and ultrastructure analyses are<br />

excellent methodological tools in studies of environmental<br />

biomonitoring with the fish as a biological mo<strong>de</strong>l. Damage<br />

<strong>de</strong>tected in cells, tissues or organs exposed to polluting<br />

agents represent an integration of cumulative effects of these<br />

substances in a physical and biochemical manner (Myers<br />

& Fournie, 2002).<br />

This work has the objective to evaluate, from a<br />

histological and ultrastructure aspect, the health of Antarctic<br />

fish Notothenia rossii and Nototehnia coriiceps, collected in<br />

different points of the Admiralty Bay – King George Island –<br />

South Shetlands Archipelago, Antarctic Peninsula.<br />

Materials and Methods<br />

In Admiralty Bay, the Antarctic fish species<br />

Notothenia coriiceps (n = 36) and Notothenia rossii (n = 26)<br />

were collected with line and hook at <strong>de</strong>pths ranging from 10<br />

to 25 meters and sacrificed, according to the Committee of<br />

Animal Experimentation-UFPR n°496. Five sampling<br />

stations were established: Coman<strong>da</strong>nte Ferraz Antarctica<br />

Station (EACF) (62° 04' 59,3" S and 58° 23' 23" W); Punta<br />

Plaza (PP) (62° 05' 26,9”S and 58° 24' 11,9”); Arctowski, in<br />

front of the Ecology Glacier (ECO) (62° 10’ 03,5” S and 58°<br />

26’ 59,8”); Botany Point (BO) (62° 06’ 15,7” S and 58° 21’<br />

14,0”) and Refúgio 2 (R2) (62° 04’ 14,5” e 58° 25’ 16,5” W).<br />

For the light microscopic analysis (MO), liver and gills<br />

were fixed in ALFAC, inclu<strong>de</strong>d in Paraplast Plus® and<br />

stained with haematoxylin and eosin (H.E) (Clark, 1981).<br />

For electronic microscopy the gills and liver were fixed in<br />

Karnovsky (1965). The analyses and documentation of<br />

the material were ma<strong>de</strong> using an electronic transmission<br />

microscope JEOL 1200EX II. The liver and branchial<br />

histopathologies were analysed and i<strong>de</strong>ntified according to<br />

Mallat (1985), Roberts (1989), Brasileiro-Filho (1994). The<br />

lesions were quantified according to Bernet’s in<strong>de</strong>x (Bernet<br />

et al., 1999).<br />

captured showed the lesion), while branchial <strong>de</strong>tachment,<br />

aneurysm and hyperplasia were found in the gills of both<br />

species (Table 1; Figure 2). Analyzing the sampling stations<br />

and species collected, the occurrence of histopathologies<br />

was punctual and only affected a small number of animals.<br />

On the N. coriiceps a slightly higher occurrence rate was<br />

noted (Figure 1). The averages of the lesions indicated<br />

by Bernet’s In<strong>de</strong>x in each sampling station and each species<br />

are shown in Figure 1, suggesting that the highest values ​<br />

for N. coriiceps indicate that the species is more sensitive.<br />

Discussion<br />

Studies report that Antarctica has been affected for some<br />

time by sporadic pollution events, generated by the intensity<br />

and variety of human activities, which have increased over<br />

recent years (Oliveira et al., 2007; Tin, 2008). The branchial<br />

<strong>de</strong>tachment or e<strong>de</strong>ma was one histopathology found in all<br />

collected animals, regardless of the species or sampling<br />

Results<br />

Histologically, the liver and branchial tissue of the<br />

N. coriiceps and N. rossii follow the pattern <strong>de</strong>scribed in<br />

literature. The liver is constituted of cells called hepatocytes<br />

and liver parenchyma (Figure 2) while the branchial strand<br />

is ma<strong>de</strong> of a primary lamella, which in turn is ma<strong>de</strong> of two<br />

rows of breathing or secon<strong>da</strong>ry lamellas (Table 1; Figure 2).<br />

Necrosis was the only liver alteration found and just<br />

in N. corriceps (20% BO, 25% EACF and 7.7% of the fish<br />

stations. This alteration acts as a <strong>de</strong>fensive mechanism,<br />

<strong>de</strong>creasing the superficial area of the gills, and increasing<br />

the spreading distance to the harmful agent (Thophon et al.,<br />

2003). Aneurysm was found only one N. rossi and<br />

five N. coriiceps, and for Van <strong>de</strong>n Heuvel et al. (2000),<br />

this <strong>da</strong>mage leads to <strong>de</strong>ath of the pillar cells, causing<br />

accumulation of blood cells in the region. Hyperplasia of<br />

the gills was the main pathology found, <strong>de</strong>tected in both<br />

species but predominant in the N. coriiceps. Hyperplasia may<br />

be a typical <strong>de</strong>fense mechanism which works by increasing<br />

the diffusal distance between the polluents and the blood<br />

flow, causing hindrance to gas exchanges (Dutta et al., 1993;<br />

Karan et al., 1998).<br />

Conclusion<br />

Liver and branchial alterations reported in this study are<br />

not specific of one harmful agent, with the possibility of<br />

being a result of physiological mechanisms or many types<br />

of physical, chemical and biological agents of Admiralty<br />

Bay. From the <strong>da</strong>ta analyzed, it can be conclu<strong>de</strong>d that the<br />

functionality of the analyzed organs was not affected and<br />

thus, may not be classified as lethal to the species un<strong>de</strong>r<br />

investigation.<br />

Abstract: The Antarctic Peninsula, a pristine natural system has been found to be very sensitive to changes in the environment<br />

arising from climate changes and anthropic activities. The plasmatic levels of various metabolic constituents in fish have been<br />

used to i<strong>de</strong>ntify the effect of environmental changes. The present study aims to establish base line of plasmatic constituents<br />

(glucose, triglyceri<strong>de</strong>s, cholesterol, total protein and albumin) concentrations in two Antarctic fish species, Notothenia rossii and<br />

Notothenia coriiceps, which are abun<strong>da</strong>nt in Admiralty Bay, King George Island, Antarctica. Blood sample collection was done by<br />

cau<strong>da</strong>l vessel puncture immediately after capture. Plasmatic levels of glucose, triglyceri<strong>de</strong>s and cholesterol were significantly higher<br />

in N. rossii, at Refuge 2 compared to the other two sites, whereas there was no significant difference in albumin and total protein<br />

concentrations from the three sites. For N. coriiceps, only the albumin levels were higher at Refuge 2 compared to the other sites.<br />

The differences in the plasma constituent’s levels may be due to the physical and chemical differences in marine environments at<br />

sampling sites, as well as the morphological and lifestyle behavior of the two fish species.<br />

Key words: Antarctica, Notothenia, biomarkers, blood<br />

Introduction<br />

Admiralty Bay is the largest embayment located in King<br />

George Island, South Shetland Islands, which presents<br />

characteristics of a fjord, with a branching system of inlets<br />

and is an Antarctic Specially Managed Area (ASMA #1)<br />

(Leal et al., 2008; Valentin et al., 2010). About 1300 species<br />

of benthic organisms are known, including 35 species of<br />

fish of 24 genera and 10 families, where Notothenia rossii<br />

and Notothenia coriiceps are in the four most abun<strong>da</strong>nt<br />

species (Skora & Neyelov, 1992; Siciński et al., 2011).<br />

The two species have different a<strong>da</strong>ptations to the water<br />

column. N. coriiceps is <strong>de</strong>mersal and se<strong>de</strong>ntary, feeds on<br />

benthic organisms, un<strong>de</strong>rgoes dormancy and metabolic<br />

suppression during winter (Campbell et al., 2008). N. rossii<br />

is semipelagic, migratory and feeds on water column<br />

prey during the summer months (Barrera-Oro, 2003;<br />

Campbell et al., 2008). The present study aims to investigate<br />

levels of plasmatic glucose, triglyceri<strong>de</strong>s, cholesterol, total<br />

proteins and albumin in two Antarctic fish species, N. rossii<br />

and N. coriiceps, at three different sites in Admiralty Bay.<br />

The studies were carried out to establish a baseline <strong>da</strong>ta<br />

for biochemical biomarkers and to un<strong>de</strong>rstand the effects<br />

of climate change and pollutants on biological response of<br />

Antarctic organisms for monitoring Admiralty Bay. This<br />

is one of the goals in Antarctic Environmental research of<br />

the Brazilian National Institute of Science and Technology-<br />

Antarctic Environmental Research (INCT-APA).<br />

Materials and Methods<br />

Specimens of N. rossii and N. coriiceps were caught at<br />

Admiralty Bay, between December 2009 and March 2010,<br />

by hook and line fishing at <strong>de</strong>pths between 10 m and<br />

20 m. The sampling sites were Glacier Ecology Inlet (ECO;<br />

62° 10’ 03.5” S 58° 26’ 59.8” W; close to penguin rookeries),<br />

Punta Plaza marine environment (PP; 62° 05’ 26.9” S and<br />

58° 24’ 11.9” W; at least 8 km from penguin rookery),<br />

and Refuge 2 (R2; 62° 04’ 24.1 S and 58° 25’ 19.2”; in the<br />

Mackeller Inlet near a glacier). In addition to these three<br />

areas, fish specimens of the two species were collected near<br />

the oil tank at EACF using fishing net. The <strong>da</strong>ta obtained<br />

for these samples were not used in this study, as the level<br />

of stress of the fish caught using the fishing net is very high<br />

compared to hook and line fishing.<br />

To minimize the effect of stress on fish specimens, the<br />

blood collection was done in less than 60 seconds after the<br />

fish was removed from the water. The blood samples were<br />

collected by cau<strong>da</strong>l vessel puncture with a heparinized<br />

syringe. The samples were centrifuged for 10 minutes at<br />

2,000 g, The plasma was transferred to cryogenic tubes<br />

and frozen in liquid nitrogen. Plasma levels of glucose,<br />

triglyceri<strong>de</strong>s, cholesterol, total proteins and albumin, were<br />

<strong>de</strong>termined using reagent kits of Labtest Diagnostic S/A.<br />

The spectrophotometer readings were carried out using a<br />

BMG Fluostar microplate rea<strong>de</strong>r on 96 wells microplates.<br />

The statistical analysis to compare the sampling sites of<br />

each species was done by one-way ANOVA followed by<br />

Tukey a posteriori multiple pair wise test. Differences were<br />

consi<strong>de</strong>red significant for p < 0.05.<br />

Results<br />

Plasmatic glucose, triglyceri<strong>de</strong>s, cholesterol, total proteins<br />

and albumin levels of N. rossii and N. coriiceps from three<br />

sampling sites are summarized in Figure 1. In N. rossii the<br />

glucose, TG and cholesterol levels in R2 were significantly<br />

higher than ECO and PP, where as total proteins levels in R2<br />

N. rossii were lower than PP. The plasmatic levels of glucose,<br />

TG and cholesterol in N. coriiceps of the three sampling<br />

sites were not significantly different, but were observed<br />

lower plasma total proteins and higher albumin levels in<br />

N. coriiceps of R2.<br />

Discussion<br />

ECO inlet is close to a large penguin colony un<strong>de</strong>r<br />

ornithogenic influence; R2 is located in the Mackellar inlet<br />

and close to a glacier; whereas the PP is far from Penguin<br />

rookeries, glaciers and scientific station. The differences<br />

in these three environments were not able to modulate<br />

the plasmatic levels of glucose, TG and cholesterol in<br />

N.coriiceps, but the same was not observed in N. rossii.<br />

The difference in the results for the two fish species could<br />

be due to functional capacities, which differ according<br />

to their lifestyle, and in turn <strong>de</strong>fines their tolerance to<br />

environmental changes (Bilyk & DeVries, 2011; Mark et al.,<br />

2012). Glycaemia has been used to indicate stress in fish<br />

(Pankhurst, 2011). The glucose metabolism has been<br />

consi<strong>de</strong>red of secon<strong>da</strong>ry energy importance, even though<br />

tissues such as brain, kidneys and gills have high glucose<br />

consumption (Enes et al., 2009). The branchial tissue of<br />

Antarctic fish has elevated oxi<strong>da</strong>tive potential for glucose,<br />

compared to monounsaturated fatty acid (Crockett et al.,<br />

1999). This way, the glicemia rise in vertebrates has been<br />

associated with energy <strong>de</strong>mands “fight to flight” reaction<br />

(Pottinger et al., 2000). The hyperglycaemia of N. rossii<br />

in R2 is not clear, but must be related to specific energy<br />

<strong>de</strong>mands, inherent to the local marine environment, and<br />

must be the aim of future studies.<br />

The lipid transport in fish is similar to that of mammals.<br />

The very low <strong>de</strong>nsity lipoprotein (VLDL) is the main<br />

carrier of TG (Nanton et al., 2006). The high levels of TG<br />

and cholesterol in N. rossii at R2 can be an indication of<br />

high levels of the VLDL. Hepatic, muscular and cardiac<br />

tissues of Antarctic fish have elevated oxi<strong>da</strong>tive potential<br />

for monounsaturated fatty acids and supports an energy<br />

metabolism based on lipid (Si<strong>de</strong>ll et al., 1995). The cause of<br />

the higher plasmatic TG at R2 is not clear, but may have a<br />

relation with N. rossii feeding behavior. The Antarctic krill is<br />

part of N. rossii diet, which is capable of migrating vertically<br />

in the water column and feeding on this crustacean during<br />

the summer. The presence of elevated levels of fluori<strong>de</strong> in<br />

the krill carapace may have a relation with higher glucose<br />

and TG levels observed in R2. Fluori<strong>de</strong> studies with non-<br />

Antarctic organisms showed that this halogen is capable of<br />

increasing the blood levels of glucose and lipid.<br />

The albumin concentration in the fish blood is low<br />

and absent in some cases (Metcalf et al., 2007). The main<br />

physiological function of this protein inclu<strong>de</strong>s the transport<br />

of fatty acids, ions and coloidosmotic pressure control. These<br />

differences can be related to the different physiological and<br />

environmental characteristics. Taking into account and<br />

comparing the base line <strong>da</strong>ta between the two species may<br />

be N. corriceps shows advantages in being used for bioassays<br />

for selection of biomarkers and monitoring programs.<br />

Conclusion<br />

The results presented showed that the marine environments<br />

of Admiralty Bay may have particularities capable of<br />

distinctly modulating glucose, TG, cholesterol, total proteins<br />

and albumin levels in the blood of Antarctic fish N. rossii<br />

and N. coriiceps. Therefore the levels of these plasmatic<br />

constituents cannot be taken as homogenous in Admiralty<br />

Bay for these fish species. This baseline study of plasmatic<br />

constituents is important to environmental monitoring in<br />

the context of climate changes.<br />

Abstract: Raising human impact and pollution in Antarctica has focused studies to verify possible biomarker for environmental<br />

monitoring. Nacella concinna is the most conspicuous macro invertebrate of the Antarctic interti<strong>da</strong>l zone. The diesel oil leakage<br />

of icebreaker Bahia Paradise reduced in 50% N. concinna populations near Palmer Scientific Station. The aim of this study was<br />

to verify the effect of diesel oil on activity of enzymes hexokinase, lactate <strong>de</strong>hydrogenase, citrate synthase, malate <strong>de</strong>hydrogenase,<br />

glucose-6-phoshate <strong>de</strong>hydrogenase, glutathione reductase, catalase, superoxi<strong>de</strong> dismutase and arginase of Nacella concinna gills.<br />

Specimens collected in Keller Peninsula were maintained in mini aquariums containing 1% or 5% of diesel oil. The results showed<br />

that the enzymes arginase, phosphofructokinase and catalase are potential biomarkers for diesel oil pollution.<br />

Introduction<br />

The gastropod Nacella concinna is the most conspicuous<br />

macro invertebrate in the Antarctic seas, with an ample<br />

geographic distribution, and has been postulated as a sentinel<br />

organism due to its capacity for bioaccumulation of heavy<br />

metals (Ahn et al., 2002). The exposure to climate to the<br />

terrestrial environment when the ti<strong>de</strong> rece<strong>de</strong>s, freezing in<br />

winter, friction of the ice on sediments and rocks, reduction<br />

of salinity due to the entry of melt waters in to the sea and<br />

the exposure to ultraviolet radiation have been consi<strong>de</strong>red<br />

the principal stress factors on the organisms that inhabit the<br />

Antarctic interti<strong>da</strong>l zones (Davenport, 2001; Peck et al., 2006;<br />

Barnes & Peck, 2008; Obermüller et al., 2011).<br />

Human presence in the Antarctic has increased<br />

significantly during the last few <strong>de</strong>ca<strong>de</strong>s and has accelerated<br />

by international scientific efforts after the International<br />

Polar year 1957/58 (Tin et al., 2009). The concerns about<br />

the pollution around scientific stations and round the<br />

Anchorage locations of shipping vessels was justified after<br />

the sinking of the icebreaker Bahia Paradise in 1989, which<br />

resulted in the leakage of 600,000L of diesel oil in the Arthur<br />

Harbor, Antarctic Peninsula, close to the Palmer Scientific<br />

Station (USA) (Kennicutt II et al., 1992). In this case, the<br />

gastropod N. concinna population was reduced by 50%<br />

and only partially recovered after one year. Bioassays of<br />

N. concinna showed that diesel oil could elevate the protein<br />

oxi<strong>da</strong>tion and the levels of glutathione peroxi<strong>da</strong>se, in<br />

addition to reducing the levels of the catalase in the digestive<br />

gland. Whereas the levels of he dismutase superoxi<strong>de</strong> were<br />

not altered (Ansaldo et al., 2005).<br />

The present study aims to verify the effect of diesel oil<br />

on the concentrations of the energy metabolism enzymes,<br />

the antioxi<strong>da</strong>nt <strong>de</strong>fense and metabolism of L-arginine in the<br />

gills, as possible biomarkers of the environmental impact.<br />

Materials and Methods<br />

Specimens of N. concinna were collected from the Keller<br />

peninsula (62 o 05’ 28.8” S and 58 o 24’ 21.3” W), close<br />

to the Brazilian Antarctic station Comman<strong>da</strong>nt Ferraz<br />

(EACF), during the period January to March 2011. The<br />

experiments were conducted in mini aquariums (2.5 L)<br />

with 10 specimens/aquarium, subjected to thermo-saline<br />

condition 0 °C and 35 psu, with 5% and 1% diesel oil and<br />

control without diesel oil. The bioassays had duration of<br />

8 <strong>da</strong>ys, aerated continuously, water changed <strong>da</strong>ily and 12<br />

hours of photoperiod without alimentation. Natural controls<br />

were established using specimens that were dissected<br />

immediately after the collection. All the tissue samples<br />

were frozen in liquid nitrogen for posterior analysis. The<br />

homogenates were prepared in the proportion of 1 g of gill<br />

for 10 mL of buffer Tris-HCL 50 mM, pH 7.4, sonicated for<br />

15 seconds, centrifuged at 12,000 x g, for 10 minutes, and the<br />

supernatants used to <strong>de</strong>termine the activities of the enzymes:<br />

hexokinase (HK) (Baldwin et al., 2007); phosphofructokinase<br />

(PFK) (Baldwin et al., 2007); lactate <strong>de</strong>hydrogenase (LDH)<br />

(Thuesen et al., 2005); citrate synthase (CS) (Saborowski &<br />

Buchholz, 2002); malate <strong>de</strong>hydrogenase (MDH) (Childress<br />

& Somero, 1979); glucose-6-phosphate <strong>de</strong>hydrogenase<br />

(G6PDH) (Ciardiello et al., 1995); glutathione reductase<br />

(GRED) (Sies et al., 1979); superoxi<strong>de</strong> dismutase (SOD)<br />

(Crouch et al., 1981); catalase (CAT) (Regoli et al., 1997);<br />

arginase (ARG) (Iyamu et al., 2008). The enzymatic activities<br />

were normalized with the concentrations of proteins,<br />

<strong>de</strong>termined by the “bicinchoninic acid” (BCA, kit QuantiPro<br />

- Sigma) method.<br />

The statistical analysis was done using Statistica 5.0<br />

for Windows. The results are presented as mean ± SEM<br />

(stan<strong>da</strong>rd error of the mean). Statistical comparison between<br />

groups was done using three way ANOVA, followed by the<br />

multiple pairwise Tukey “a posteriori” comparison test.<br />

Levene’s test was used to <strong>de</strong>termine the homosce<strong>da</strong>sticity of<br />

the <strong>da</strong>ta, and a log x correction was applied when required.<br />

Differences were consi<strong>de</strong>red significant for p < 0.05.<br />

Results<br />

The effect of two different concentrations of diesel oil (D1%<br />

and D5%) on the gill levels of HK, PFK, LDH, CS, MDH,<br />

G6PDH, GRED, CAT, SOD and ARG, in the thermo-saline<br />

0-35 experimental condition are summarized in Figure 1.<br />

The increase in the levels of HK, GRED and SOD, as well as<br />

reduction of MDH and G6PDH, observed in the presence<br />

of diesel oil were not significant. The PFK levels were<br />

upregulated in the presence of diesel oil 5% (D5%), whereas<br />

CAT with D5% was downregulated. The levels of ARG were<br />

significantly upregulated in the presence of D%5.<br />

Discussion<br />

The enzymes LDH, MDH and CS have been used as markers<br />

of potential anaerobic and aerobic ATP generators in the<br />

cells (Torres & Somero, 1988) The branchial levels of LDH,<br />

MDH and CS are not influenced by the presence of diesel<br />

oil, indicating that the aerobic and anaerobic metabolic<br />

pathways may not be influenced by the diesel oil effect in this<br />

tissue. The principal glycolytic pathway regulator enzyme<br />

PFK levels were upregulated in the presence of diesel oil. The<br />

enzymes G6PDH, GRED and SOD, directly or indirectly,<br />

participate in the cellular antioxi<strong>da</strong>nt <strong>de</strong>fense. G6PDH<br />

catalyze reducing reactions of NADP + to NADPH+H + ,<br />

GRED reduces glutathione and SOD <strong>de</strong>composes O 2–<br />

. SOD<br />

is often called the primary <strong>de</strong>fense against oxi<strong>da</strong>tive stress<br />

because superoxi<strong>de</strong> is strong initiator of chain reaction and<br />

may the raise in the levels of SOD can be related to the raise<br />

of superoxi<strong>de</strong> in the presence of diesel oil. CAT is part of the<br />

antioxi<strong>da</strong>nt <strong>de</strong>fense enzymes and does the <strong>de</strong>composition<br />

of 2H 2<br />

O 2<br />

in H 2<br />

O and O 2<br />

. It was downregulated in the<br />

presence of diesel oil. The levels of ARG were upregulated<br />

in the presence of diesel oil. This enzyme participate in the<br />

intracellular control of phospo-L-Arginine, nitric oxi<strong>de</strong> and<br />

polyamines levels (Wu & Morris Junior, 1998).<br />

The levels of CS, LDH and SOD are significantly higher<br />

in natural control than in experimental control (Figure 1).<br />

The elevated levels of SOD in the natural control can<br />

be related to this gastropod migration to the interti<strong>da</strong>l<br />

zone during the austral spring and its exposition to more<br />

elevated temperature, which could be inducing increase<br />

in SOD (Abele et al., 1998). The thermic stress has effect<br />

on the energy <strong>de</strong>mand of N. concinna and is capable of<br />

reducing ATP levels, lift the oxygen consumption and down<br />

Conclusion<br />

The elevated levels of enzymes CS, LDH and SOD in gills of<br />

nature controls in relation to experimental control (thermosaline<br />

condition 0-35), showed that natural stress imposed<br />

by the ambient conditions of the interti<strong>da</strong>l zone is capable<br />

of upregulating these enzymes levels. The enzymes ARG,<br />

PFK and CAT can be used as potential biomarkers for<br />

diesel oil pollution, consi<strong>de</strong>ring that: a) the natural stress in<br />

the interti<strong>da</strong>l zone was not capable of inducing expressive<br />

alterations in these enzymes compared to experimental<br />

controls; b) diesel oil induced significant alterations in<br />

these enzymes levels; c) except PFK, the effect of diesel oil<br />

on the ARG and CAT enzymes levels was more intense in<br />

the experimental condition of 5% than at 1%.<br />

Abstract: Phytal ecosystems are characterized as an important area of production and energy transference, due to the complex<br />

trophic web that naturally establishes between diverse organism groups that co-inhabit this eutrophic region. Benthic organisms,<br />

especially of the macro- and meiobenthic, constitute the associated fauna of the phytal kelps. Himantothallus grandifolius is the<br />

most prominent Antarctic kelp species. It is usually found in the Antarctic Peninsula Islands of the Maritime Antarctic region,<br />

<strong>de</strong>spite the ecological importance of associated fauna. The present work has the objective to evaluate qualitatively and quantitatively<br />

the macrofauna phytal of the H. grandifolius collected in February 2011 at Mackelar inlet (Admiralty Bay), with special focus<br />

on taxonomic <strong>de</strong>termination of the associated Isopods fauna. Preliminary results showed that the dominant faunal group was<br />

Amphipods (n = 1776), followed by Ectoprocta (n = 496). Isopods occurred in fewer <strong>de</strong>nsity (n = 207 ind.) and so far have been<br />

i<strong>de</strong>ntified at the following family level (Gnathii<strong>da</strong>e, Munni<strong>da</strong>e, Plakarthi<strong>da</strong>e, Jaeropsi<strong>da</strong>e , Sphaeromathi<strong>da</strong>e and Janiri<strong>da</strong>e).<br />

Keywords: Kelps, Himantothallus grandifolius, phytal fauna, Isopods<br />

Introduction<br />

The seaweed and seagrass communities have a great<br />

importance in the <strong>de</strong>velopment of invertebrate and<br />

vertebrate communities, creating favorable conditions of<br />

habitat, shelter, feeding, reproduction and <strong>de</strong>velopment<br />

for the life cycles of various marine organisms. The marine<br />

biocenosis constituted by animals that live associated to<br />

these plant-substrates is <strong>de</strong>signated phytal (Masunari &<br />

Forneris, 1981; Remane, 1933; Masunari, 1987). Phytal<br />

communities are mainly composed by invertebrates of the<br />

macrofauna (0.5 to 2 mm) and meiofauna (0.045 to 0.5 mm)<br />

size classes. In Admiralty Bay Antarctica, especially in,<br />

phytal communities are very little studied (Pabis & Sincinski,<br />

2010; Sicinski et al., 2011). Over all, in Admiralty Bay there<br />

are some 36 macroalgae species (Zielinski, 1990) and the<br />

Desmarestiaceae is the most common family. From the<br />

36 species Himantothallus grandifolius is the most common<br />

kelp in the whole Bay. H. grandifolius a Heterokontophyta<br />

algae constituted by leaf-like thallus with corrugate edges<br />

narrowing downwards forming a short stipe, which can<br />

reach a large size both in width, more than 1m, and <strong>de</strong>pth of<br />

between 5-15 m in total length. This kelp is found attached to<br />

rocks and stones by a great number of appen<strong>da</strong>ges forming<br />

a strong holdfast. Thallus and holdfast of these large brown<br />

algae are consi<strong>de</strong>red to be structurally complex habitats<br />

(Steneck et al., 2002), consisting in a rich aggregation in<br />

a sublittoral zone ranging within a <strong>de</strong>pth of 10 to 90 m<br />

(Zielinski, 1990).<br />

Phytal fauna of the Admiralty Bay is often composed of<br />

Amphipods, Isopods, Polychaetes, bryozoans and ascidians<br />

like the phytal in other places of the world (Mukai, 1971;<br />

Kito, 1975; Hicks, 1977; Coull & Wells, 1983; Johnson<br />

& Scheibling, 1987; Preston & Moore, 1988; Curvêlo &<br />

Corbisier, 2000; Krzysztof & Sicinski, 2010). There are<br />

few studies on Antarctic macroalgae phytal communities,<br />

<strong>de</strong>spite their great importance in marine coastal ecosystems.<br />

The aim of the present study was to <strong>de</strong>scribe phytal<br />

macrofauna composition associated to H. grandifolius in<br />

Admiralty Bay, emphasizing Isopod fauna composition.<br />

Materials and Methods<br />

Admiralty Bay is located in the King George Island<br />

in the central region of South Shetlands Archipelago<br />

(Rakusa‐Suszczewski, 1980) 62° 05” S and 58° 24” W. The<br />

bay covers some 122.08 km 2 (Battke, 1990) and is comprised<br />

of three inlets, Martel, Mackelar and Ezcurra. It is the largest<br />

bay of King George Island, and about 30% of the bottom of<br />

Admiralty Bay is covered by macroalgae. The specimen of<br />

Himantothallus grandifolius was collected in Mackelar inlet<br />

near Peruvian Station of Machu Pichu up at 15 meters <strong>de</strong>ep<br />

in February 2011. The specimen measured approximately<br />

8 m long and 60 cm wi<strong>de</strong>. The holdfast was circular and the<br />

diameter was approximately 45 cm. After collecting this<br />

specimen, it was stored and frozen immediately. In Brazil,<br />

the specimen was thawed (<strong>de</strong>frosted) at room temperature<br />

(25 °C) in Macroalgae laboratory (Biology Institute/<strong>UFRJ</strong>).<br />

During thawing, the organisms associated to seaweed were<br />

carefully collected and immediately fixed in neutralizing<br />

formal<strong>de</strong>hy<strong>de</strong> 4%. The holdfast was washed to remove the<br />

sediment and organisms. The sediment was elutriated and<br />

the supernatant was poured on two sieves with meshes<br />

of 0.500 and 0.045 mm to separate the macrofauna and<br />

meiofauna organisms. Macrofauna organisms were sorted<br />

into higher taxonomic levels (Phylum, Class, Or<strong>de</strong>r, and<br />

others). The Isopods were separated for preliminarily<br />

taxonomic i<strong>de</strong>ntification to Family level and expressed in<br />

number of individuals found across the seaweed thallus<br />

and holdfast.<br />

The holdfast was the thallus region with the greater<br />

diversity. There are a relatively small number of studies<br />

focused on the fauna of Antarctic and Subantarctic<br />

macroinvertebrates associated with holdfasts of various<br />

macroalgae (Arnaud, 1974).<br />

Discussion<br />

Frequently, the dominant groups of the phytal fauna are<br />

Peracarids Crustacea, especially Amphipods, Isopods,<br />

Tanai<strong>da</strong>ceans (Mukai, 1971; Kito, 1975; Hicks, 1977; Coull<br />

& Wells, 1983; Johnson & Scheibling, 1987; Preston &<br />

Moore, 1988; Curvêlo & Corbisier, 2000), similar with the<br />

faunal composition observed in the present work. Through<br />

the taxonomic i<strong>de</strong>ntification it has been possible from the<br />

results obtained so far to suggest that holdfast was the region<br />

with the greatest diversity of organisms. The latter can be<br />

explained by the morphological aspects of the holdfast such<br />

as textures and interstitial spaces that accumulate sediment,<br />

<strong>de</strong>bris and epiphytes, in addition to providing a greater<br />

<strong>de</strong>gree of protection from as wave exposure and pre<strong>da</strong>tors<br />

(Muralikrishnamurty, 1983; Preston & Moore, 1988).<br />

The Antarctic marine environment is very peculiar, and<br />

presents features like extremely low and stable seawater<br />

temperature, 4 °C a –70 °C, marked differences in the<br />

inci<strong>de</strong>nce of light throughout the year, small fluctuations<br />

in salinity during the summer and a marked seasonality<br />

in food resource input in relation to the annual cycle of<br />

primary productivity (Gutt, 2007). In this environment,<br />

large macroalgae (Kelps) modify physical factors such as<br />

light or water movement and can play a fun<strong>da</strong>mental role<br />

on the distribution patterns and diversity of the marine<br />

organisms (Reed & Foster 1984, Bulleri et al., 2002).<br />

Abstract: Antarctica is not as isolated as once thought. Although persistent and invasive species have not been <strong>de</strong>tected in the<br />

marine environment, some transient species have been. In the present study we investigate the biogeographical patterns of 529<br />

benthic species of 5 target phyla recor<strong>de</strong>d in the Admiralty Bay consi<strong>de</strong>ring that it is an important tool for the i<strong>de</strong>ntification of<br />

species origin. Most species of Admiralty Bay of the studied phyla are en<strong>de</strong>mic to Sub Antarctica and Antarctica. The second<br />

highest percentage was of species with continuous distribution. Chor<strong>da</strong>ta and Anneli<strong>da</strong> presented the highest number of disjoint<br />

species. However most disjoint species predominate in Antarctica and Sub Antarctica indicating their origin in the Southern<br />

Ocean. Cosmopolitan patterns appear to be correlated to taxonomic misi<strong>de</strong>ntification or to the occurrence of cryptic species that<br />

are being revealed by molecular studies. Only a few disjoint species <strong>de</strong>serve further investigation.<br />

Keywords: bioinvasion, biogeographical patterns, en<strong>de</strong>mism<br />

Introduction<br />

Bioinvasion means the movement of species into an area<br />

beyond their natural range, as a result of human activity.<br />

In Antarctica this inclu<strong>de</strong>s movement of species between<br />

biogeographic zones. The main barrier to introductions<br />

of non indigenous species (NIS) in the Southern Ocean<br />

is the physical dissimilarity between donor and recipient<br />

areas. There are no records of persistent and invasive non<br />

indigenous species in the Antarctic marine environment.<br />

So, why are we concerned about bioinvasion in maritime<br />

Antarctica?<br />

We know now that Antarctica is not as isolated as once<br />

thought (Clarke et al., 2005). Non native organisms including<br />

terrestrial invertebrates and plants, marine Crustacean<br />

(adult and larvae) and algal <strong>de</strong>nse mats of an introduced<br />

species (Enteromorpha intestinalis) have already been found<br />

in the Antarctic environment (Frenot et al., 2005). The<br />

rapid regional warming of the Antarctic Peninsula during<br />

the last 50 years also leads to more favorable conditions of<br />

establishment of non indigenous species (Convey, 2006).<br />

Another factor that influences bioinvasion rates is the<br />

transport of people and goods that are increasing due to<br />

logistic, scientific, fisheries and tourism activities every<br />

year. Finally, non native species is the highest priority issue<br />

in the CEP (Committee on Environmental Protection) five<br />

year work plan highlighting that we need to be proactive.<br />

Carlton (2009) listed 12 potential sources of errors<br />

that have led to inva<strong>de</strong>r un<strong>de</strong>restimation. The lag time in<br />

recognizing that an introduced species has been mistakenly<br />

re<strong>de</strong>scribed ranges from months to over 100 years. Although<br />

two hundred terrestrial plants and animals have been<br />

recognized as introduced in the sub Antarctic islands there<br />

are no records for the marine environment.<br />

Consi<strong>de</strong>ring these facts, the investigation of<br />

biogeographical patterns is an important tool for the<br />

i<strong>de</strong>ntification of species origin. This study has investigated<br />

biogeographical patterns of benthic species recor<strong>de</strong>d in<br />

Admiralty Bay.<br />

158 | Annual Activity Report 2011


Materials and Methods<br />

The study of species distribution focused on species of five<br />

target phyla (Mollusca, Echino<strong>de</strong>rmata, Anneli<strong>da</strong>, Artropo<strong>da</strong><br />

and Chor<strong>da</strong>ta) found in Admiralty Bay and are available in a<br />

list at the site www.abbed.uni.lodz.pl, referring to the survey<br />

conducted by Sicinski et al. (2011). The study was ma<strong>de</strong> using<br />

the online <strong>da</strong>tabase OBIS – Ocean Biogeography Information<br />

System (OBIS, 2012) and GBIF – Global Biodiversity<br />

Information Facility (GBIF, 2012). According to the<br />

distribution pattern in marine biogeographic zones proposed<br />

by Rass (1986), species were classified as: I) cosmopolitan: for<br />

those of wi<strong>de</strong> distribution and that are present in at least three<br />

ocean basins; II) continuous: for species located in adjacent<br />

biogeographic areas (but at a lower rate than required for<br />

classification as cosmopolitan), III) disjoint: species that<br />

have occurrences in distinct biogeographic regions (separated<br />

by areas of non-occurrence); IV) en<strong>de</strong>mic: for species<br />

distributed within the boun<strong>da</strong>ries of the Southern Ocean<br />

(Sub Antarctica and Antarctica).<br />

Results<br />

The number of macrozoobenthos taxa of the phylum<br />

Anneli<strong>da</strong>, Arthropo<strong>da</strong>, Mollusca, Echino<strong>de</strong>rmata and<br />

Chor<strong>da</strong>ta recor<strong>de</strong>d by Sicinski et al. (2011) was 603. In<br />

this study, we analyzed the distribution pattern of taxa<br />

i<strong>de</strong>ntified at species level, totalling 529 species (87.7%).<br />

The phylum Arthropo<strong>da</strong> showed the largest number of taxa<br />

(257), proving to be the one with the greatest biodiversity<br />

in the marine environment of Admiralty Bay from the<br />

phyla studied. The phylum Chor<strong>da</strong>ta registered the lowest<br />

number of taxa (16).<br />

Most species of Admiralty Bay phyla studied are en<strong>de</strong>mic<br />

to Sub Antarctica and Antarctica (Figure 1). The highest<br />

percentage of en<strong>de</strong>mic species was found to the phylum<br />

Echino<strong>de</strong>rmata. The second highest percentage was of<br />

species with continuous distribution. The phylum Chor<strong>da</strong>ta<br />

had the highest percentage of species with this distribution.<br />

Most cosmopolitan species were from the phyla Anneli<strong>da</strong>.<br />

The percentage of disjoint species of Chor<strong>da</strong>ta and Anneli<strong>da</strong><br />

were the highest among the phyla studied. Some species were<br />

not found in <strong>da</strong>tabases, and the phylum Anneli<strong>da</strong> presented<br />

the highest percentage of species with no <strong>da</strong>ta (Figure 1).<br />

Cosmopolitan (Table 1) and Disjoint (Table 2) species were<br />

classified according to their dominance pattern in Antarctica,<br />

Sub Antarctica, South America and other bioregions.<br />

Discussion<br />

The introduction of a species is not always documented.<br />

Species that were introduced many years ago (historical<br />

introductions) are already in complete equilibrium with<br />

the native biota (Villac et al., 2008). Cosmopolitan species<br />

are often classified as cryptogenic, species that cannot be<br />

recognized as native or introduced (Carlton, 2009). In NIS<br />

surveys cryptogenic species are often indicated as potential<br />

introduced species to avoid un<strong>de</strong>restimation of bioinvasion<br />

un<strong>de</strong>r a precautionary approach.<br />

In the present study we investigated the species origin of<br />

44 species that presented a disjoint or cosmopolitan pattern<br />

of distribution from their dominance pattern in Antarctica,<br />

Sub Antarctica, South America and other bioregions.<br />

The biogeographical patterns of species with few records<br />

cannot be well established. Cosmopolitan patterns appear<br />

to be correlated to taxonomic misi<strong>de</strong>ntification or to the<br />

occurrence of cryptic species. Particularly cosmopolitan<br />

patterns with few records in Antarctica and Sub Antarctica<br />

are probably a complex of species that are being revealed<br />

by molecular studies. Most disjoint species predominate<br />

in Antarctica and Sub Antarctica indicating their origin in<br />

the Southern Ocean. Only a few disjoint species, especially<br />

for the most number of records in South America, <strong>de</strong>serve<br />

further investigation.<br />

Conclusion<br />

The great majority of investigated species were en<strong>de</strong>mic<br />

to the Southern Ocean. The second highest percentage<br />

was of species with continuous distribution. Disjoint and<br />

cosmopolitan species represented only 8.3% of the total.<br />

The results obtained do not allow us to make conclusions<br />

about which species were introduced to the Southern Ocean.<br />

However they provi<strong>de</strong> <strong>de</strong>tailed information about disjoint<br />

and cosmopolitan species indicating which species <strong>de</strong>serve<br />

further investigation.<br />

Abstract: Tardigra<strong>da</strong> are among the microinvertebrates commonly associated to terrestrial vegetation, especially in<br />

extreme environments such as Antarctica. In the austral summer 2010/2011, Tardigra<strong>da</strong> were found in high <strong>de</strong>nsities on<br />

Prasiola crispa sampled at penguin rookeries from Arctowski Station area (King George Island). Taxonomic i<strong>de</strong>ntifications<br />

performed to <strong>da</strong>te suggest that the genus Ramazzottius is the dominant taxa on P. crispa. This genus has been reported for West<br />

Antarctica and Sub-Antarctic Region. In this context, the present work intends to contribute to the knowledge of the terrestrial<br />

invertebrate fauna associated to P. crispa of the ice-free areas around Admiralty Bay.<br />

Keywords: microinvertebrates, terrestrial macroalgae, tardigra<strong>da</strong>, Ramazzottius<br />

Introduction<br />

Tardigra<strong>da</strong> are micrometazoans (average 250-500 µm) that<br />

present a large distribution in variety of diverse habitats, from<br />

rain forests to arid polar environments, including nunataks<br />

and mountain tops to abyssal plains of the oceanic regions<br />

(Brusca & Brusca, 2007; McInnes, 2010a). In terrestrial<br />

environments, Tardigra<strong>da</strong> are abun<strong>da</strong>nt, especially in<br />

mosses and lichens, which is the main component of the<br />

crypticfauna. Many linmo-terrestres tardigra<strong>de</strong>s can survive<br />

to total <strong>de</strong>siccation in a state of cryptobiosis (ametabolic<br />

state) that is a protection against <strong>de</strong>siccation and freezing<br />

un<strong>de</strong>r natural conditions, but anydrobiosis also allows a<br />

resistance against unnatural abiotic extremes (Jönsson &<br />

Bertolani, 2001). Actually, about 800 species of Tardigra<strong>da</strong><br />

have been <strong>de</strong>scribed from marine, freshwater and terrestrial<br />

environments (Nelson & Marley, 2000).<br />

Antarctic Tardigra<strong>da</strong> were at the beginning <strong>de</strong>scribed<br />

by Murray (1906) and Richters (1908) (apud Convey &<br />

McInnes, 2005), after species lists of Antarctic Tardigra<strong>da</strong><br />

were prepared by Morikawa (1962), Sudzuki (1964),<br />

Jennings (1976, 1979) and Utsugi & Ohyama (1989, 1993).<br />

Tardigra<strong>da</strong> species are currently known from the continental<br />

and Maritime Antarctica biogeographical zones (Pugh,<br />

1993; Convey & McInnes, 2005). Actually, 17 genera and<br />

48 species have been <strong>de</strong>scribed for associated fauna of<br />

terrestrial vegetation of ice-free areas in Antarctica and Sub-<br />

Antarctica regions (McInnes, 2010b), 11 of these species<br />

were reported for King George Island (South Shetland<br />

Islands, Maritime Antarctica) by Utsugi & Ohyama (1993).<br />

In King George Island, terrestrial vegetation is almost<br />

exclusively cryptogamic, comprising mostly mosses,<br />

liverworts, lichens, algaes (Smykla et al., 2007). In this<br />

island, mats of the nithphilous algae Prasiola crispa occupy<br />

wet areas extremely high nutrient concentration at active<br />

rookeries at the coastal regions around Admiralty Bay (South<br />

Shetland Islands, Maritime Antarctica) (Smykla et al., 2007).<br />

According to Jennings (1976, 1979) this foliaceae algae is<br />

among the substrates with higher faunal species richness<br />

and Tardigra<strong>da</strong> is among these organisms (Broady, 1989).<br />

Nevertheless, Antarctic terrestrial biota is known to<br />

have low diversity, a high <strong>de</strong>gree of en<strong>de</strong>mism and clear<br />

patterns of biogeographic distribution <strong>de</strong>fined by consistent<br />

biological and climatic differences (Convey & McInnes,<br />

2005; Convey & Stevens, 2007). Ad<strong>de</strong>d to this, the Antarctic<br />

terrestrial biota inclu<strong>de</strong> organisms ecophysiology a<strong>da</strong>pted to<br />

environmental pressures involving very low temperatures,<br />

nutrient limitation, environmental radiation, lack of liquid<br />

water, <strong>de</strong>siccation and physical abrasion (Convey et al.,<br />

2008). Recent studies have shown that this biota has an<br />

ancient origin and has persisted in isolation for ten million<br />

years (Convey & Stevens, 2007; Convey et al., 2009;<br />

Chow & Convey, 2007). These characteristics result in the<br />

terrestrial communities of Antarctica being particularly<br />

sensitive to the effects of human presence in the region<br />

and to climate change. In this context, the present study<br />

intends to contribute to the knowledge of the composition<br />

of the Tardigra<strong>da</strong> assemblages on the terrestrial macroalgae<br />

Prasiola crispa of the ice-free areas around Admiralty Bay.<br />

Materials and Methods<br />

Prasiola crispa were sampled on the rocks and soil adjacent<br />

to the penguin rookeries of Ornithologist Stream area (Polar<br />

Polish Arctowski Station, King George Island) in January<br />

2011 (XXIX Brazilian Antarctic Operation) (Figure 1).<br />

Three samples of 3 cm² were observed in vivo and<br />

later preserved in formal<strong>de</strong>hy<strong>de</strong> 4% for posterior analysis,<br />

quantification and i<strong>de</strong>ntification of the fauna. In the<br />

Figure 1. Location of Admiralty Bay (King George Island, South Shetland Islands, Antarctic Peninsula), highlighted the scientific stations of Brazil and Poland.<br />

laboratory the organisms were separated through sieves<br />

(500 and 38 µm size meshes). After the total organism<br />

quantifications un<strong>de</strong>r stereoscopic microscope, Tardigra<strong>da</strong><br />

specimens were removed and post fixed in GAW solution<br />

(Glycerin - Acetic acid - Water), before being passed<br />

through a glycerol series and mounted in Faure’s medium<br />

(McInnes et al., 2001). After drying, sli<strong>de</strong>s were ringed with<br />

glycerol. Taxonomic i<strong>de</strong>ntifications were performed by<br />

optical microscopy and based on Pilato & Bin<strong>da</strong> (2010) keys.<br />

Results<br />

The associated microfauna of Prasiola crispa were composed<br />

by Rotifera, Nemato<strong>da</strong>, Tardigra<strong>da</strong>, Acari and Collembola.<br />

Tardigra<strong>da</strong> was the taxa found in greatest <strong>de</strong>nsity, up to<br />

7002,67 ind.cm –2 (x = 2842,11 ind.cm –2 , n = 3) (Table 1),<br />

representing 66% of the total microfauna. The taxonomic<br />

i<strong>de</strong>ntifications conducted so far indicate that the specimens<br />

found Tardigra<strong>da</strong> specimens belong to the Family<br />

Hypsibii<strong>da</strong>e, genus Ramazzotius Bin<strong>da</strong> & Pilato, 1986. Other<br />

i<strong>de</strong>ntifications still in progress, and at the end i<strong>de</strong>ntified<br />

specimens will be <strong>de</strong>posited in the collection.<br />

Discussion and Conclusion<br />

Jennings (1976) when studied the Tardigra<strong>da</strong> from the<br />

Antarctic Peninsula and Scotia Ridge Region found a<br />

high dominance of tardigra<strong>da</strong> only on sites of the foliose<br />

alga Prasiola crispa. According Convey & McInnes (2005)<br />

some terrestrial ecosystems dominated by Tardigra<strong>de</strong>s, and<br />

organisms which would generally be ubiquitous such as<br />

Nemato<strong>de</strong> can also very often be absent. This showed the<br />

Tardigra<strong>da</strong> preference for the relatively rich organic soils<br />

rather than moss and peat substrates.<br />

At the moment, taxonomic i<strong>de</strong>ntifications showed<br />

that Tardigra<strong>da</strong> specimens foun<strong>de</strong>d on the Prasiola<br />

crispa samples from Ornithologist Stream are the family<br />

Hypsibii<strong>da</strong>e and genus Ramazzotius Bin<strong>da</strong> & Pilato, 1986.<br />

The Hypsibii<strong>da</strong>e family are a significant and dominant in<br />

polar habitats (McInnes & Pugh, 2007). This dominance<br />

cannot be explained only by the fact that it possesses features<br />

such as cold tolerance (Cryptobiosis), aerial dispersion or<br />

partenogenisis, whereas other families (e.g. Macrobioti<strong>da</strong>e,<br />

Echisci<strong>da</strong>e) also have such features. McInnes (2007) suggest<br />

that this dominance was more likely to food sources,<br />

many Hypsibii<strong>da</strong>e are hydrophilic, bactereophages and/<br />

or algivores, a factor that can be an advantage to colonize<br />

polar habitats.<br />

Ramazzottius are cosmopolitan genus (Ramazzotti &<br />

Maucci, 1983). Ramazzottius are wi<strong>de</strong>spread throughout<br />

the world (Ramazzotti & Maucci, 1983; McInnes, 1994),<br />

including the previous record of Antarctica continental and<br />

sea. Among the many collection of bryophytes, species of<br />

Echiniscus, Hypsibius, Macrobiotus (and segregate genera),<br />

Milsenium and Ramazzottius seem particularly common.<br />

The genus Ramazzottius is characterized by Hypsibius-type<br />

claws, but only Ramazzottius has a long and straight basal<br />

portion on the outer claw more strongly <strong>de</strong>veloped than<br />

the secon<strong>da</strong>ry branch in addition to a thin main branch<br />

inserted high on the basal portion by means of a flexible<br />

tract (C) (Bertolani & Rebecchi 1993). Sometimes this<br />

tract is very lightly sclerified and the primary branch seems<br />

almost completely separate from the rest of the claw (Nelson<br />

The issues related to comfort and security for a building in<br />

Antarctica are also, necessarily, related to environmental<br />

factors, due to the specific characteristics of the Antarctic<br />

environment. Thus, over the years, the group of researcher<br />

scientists related to technology and environmental<br />

management have sought to improve specific aspects, at<br />

certain moments having as their objective the efficacy of<br />

systems already adopted by Brazil at their Brazilian Station<br />

– Coman<strong>da</strong>nte Ferraz (from now on EACF, Portuguese<br />

acronym), and at other times opening new frontiers of study<br />

from the previous results obtained.<br />

This year, among the main results obtained, the most<br />

noteworthy was the research in the field of acoustics, now<br />

with a focus on its influence on the psychological behaviour<br />

of the users. The article, “Relationship between noise and<br />

psychological comfort of the users in the Coman<strong>da</strong>nte Ferraz<br />

Antarctic Station” evaluates the question of noise using as<br />

instrument correlated national and international norms, and<br />

furthermore, offers a warning regarding the conditions of<br />

specific exposure to be consi<strong>de</strong>red in different ambiences<br />

such as might be found in a building in Antarctica.<br />

Attention is called to pioneer research un<strong>de</strong>rtaken in this<br />

period, “Analysis of Indoor Al<strong>de</strong>hy<strong>de</strong>s in the Coman<strong>da</strong>nte<br />

Ferraz Antarctic Station”, which studied the quality of indoor<br />

air, with strong emphasis on volatile organic composites,<br />

especially the al<strong>de</strong>hy<strong>de</strong>s, whose presence in the flooring and<br />

the furniture has reinforced the need for monitoring. In the<br />

research it was established that in some locations of EACF,<br />

the concentration of formal<strong>de</strong>hy<strong>de</strong> surpassed the directives<br />

proposed by the WHO – World Health Organization,<br />

making evi<strong>de</strong>nt the necessity for more attention to this<br />

matter.<br />

The article “Results of internal audit in the environmental<br />

management system of Brazilian Antarctic Scientific Station<br />

Coman<strong>da</strong>nte Ferraz” shows the results of the internal audit<br />

un<strong>de</strong>rtaken between December 2011 and January 2012 at<br />

EACF, having as principle references the Madrid Protocol<br />

and the stan<strong>da</strong>rd ISO 14001:2004. It was verified that<br />

EACF has a partial level of conformity of 86.2% in relation<br />

to the requirements of ISO 14001:2004, which serves as<br />

fun<strong>da</strong>mental information in <strong>de</strong>lineating an Environmental<br />

Management Programme.<br />

If on the one hand there is vital concern in reducing the<br />

impacts occasioned by human occupation of Antarctica, on<br />

the other hand, it is necessary to <strong>de</strong>al with strategies that<br />

seek to recover the consoli<strong>da</strong>ted impacts. In this respect,<br />

the article “Bioremediation of the diesel-contaminated soil<br />

of the Brazilian Antarctic Station”, presents an alternative<br />

proposal for the treatment of areas contaminated by oil –<br />

which inclu<strong>de</strong>s the essential <strong>de</strong>epening of the research -,<br />

especially of those related to the leakage of fuel. The partial<br />

results were obtained from the carrying out of a successful<br />

experiment un<strong>de</strong>rtaken ex situ.<br />

Thus, Thematic Area 4, restates it vocation of incentivising<br />

research in the areas of technology and management<br />

consi<strong>de</strong>ring the useful lifecycle of a building, which<br />

extends from planning (prevention); usage and operation<br />

(management) until the final <strong>de</strong>stination, recycling or<br />

removal of the installations (recovery).<br />

Abstract: The Coman<strong>da</strong>nte Ferraz Antarctic Station is a base camp and working place, housing a diversity of individuals in a<br />

restricted environment. Comfort is an essential criterion for the resi<strong>de</strong>nce time to be effectively productive, in particular in relation<br />

to acoustics. The relevance of this study is based on the correlation between noise levels <strong>da</strong>ta and potential effects on the human<br />

body, in addition to contributing to the creation of noise prevention methods. The purpose of this paper is to assess the impact of<br />

noise levels on psychological comfort of the researchers of that Station. The <strong>da</strong>ta was gathered in situ, during XXVIII Antarctic<br />

Operation, according to the Brazilian Technical Stan<strong>da</strong>rd for measurement procedures and additional parameters <strong>de</strong>veloped for<br />

the Station. Then, the systematization and analysis were carried out, and subsequently a mapping with mean noise levels was<br />

<strong>de</strong>veloped and the potential correlations with physical, physiological and psychological effects on human beings were verified.<br />

In some working environments the noise levels did not meet the comfort parameters; however they consi<strong>de</strong>r an 8-hour work<strong>da</strong>y.<br />

In the remaining environments whose activities are of rest and work, only the adjacent outdoor points were analyzed, where the<br />

required isolation stan<strong>da</strong>rds for sealing materials were found. Even though additional actions for further research were required,<br />

such as questionnaires and users physical evaluation, the outcomes obtained so far will serve as aid for the construction of new<br />

buildings that will make up the Station, with emphasis on the necessity of acoustic treatment of the environments to reduce noise<br />

from outdoor and indoor activities, especially in long term research locations.<br />

Introduction<br />

Sound is the propagation of mechanical energy through<br />

material medium in the form of wave motion, irradiated<br />

three-dimensionally in all directions. While sound has a<br />

<strong>de</strong>fined frequency, noise is a vibratory physical phenomenon<br />

with un<strong>de</strong>fined characteristics of pressure and frequency,<br />

disharmoniously mixed with each other (Grandjean, 1988<br />

apud Abrahão et al., 2009). It is the ear that captures the<br />

sounds and noise vibrations, allowing communication and<br />

as well acting as an alarm system for the body. When the<br />

hearing system is exposed to high magnitu<strong>de</strong> sounds and<br />

noises, not only is its function affected but it also results<br />

in physical, psychological and physiological harm. Longterm<br />

exposure can lead to hearing loss and extra-hearing<br />

disor<strong>de</strong>rs.<br />

The purpose of this research was to assess the impact of<br />

noise levels on the psychological comfort of the researchers<br />

of the Coman<strong>da</strong>nte Ferraz Antarctic Station (EACF,<br />

Portuguese acronym). The hypothesis was that the noise<br />

levels generated by maintenance and operational equipment<br />

both outdoors and indoors at EACF may cause acoustic<br />

discomfort to the users.<br />

The relevance of this study is based on the correlation<br />

between the noise level <strong>da</strong>ta, according to the environments,<br />

and the potential effects on the human body. It has also<br />

contributed with <strong>da</strong>ta to create prevention methods in<br />

buildings based in Antarctica, such as using techniques<br />

and materials that do not <strong>de</strong>mand using noisy equipment<br />

for their maintenance and the specification of more silent<br />

operating equipment, and also ways to control noise, with<br />

materials such as acoustic isolation (soundproofing) of the<br />

environments that have transmitting equipment. This study<br />

also generates additional reflections that can be used outsi<strong>de</strong><br />

the Antarctic environment, with application to the reality<br />

of urban spaces, for example. However, the great difference<br />

between the comfort conditions for an urban worker and<br />

the specific condition of the users of a Scientific Station are<br />

highlighted, where the stress situation and the confinement<br />

may contribute to enhance the sensation of discomfort.<br />

Materials and Methods<br />

The <strong>da</strong>ta was collected in situ by trained researchers from<br />

the Planning and Projects Laboratory of the Fe<strong>de</strong>ral<br />

University of Espírito Santo during the XXVIII Antarctic<br />

Operation in a period of 15 nonconsecutive <strong>da</strong>ys (due to<br />

climatic variations), from 02 to 22 December 2009. The<br />

measurement procedure followed the recommen<strong>da</strong>tions of<br />

the Brazilian Technical Stan<strong>da</strong>rd NBR 10151 (ABNT, 1987a)<br />

and a methodology <strong>de</strong>veloped specifically for EACF, because<br />

it is a different environment from the Brazilian one, where<br />

some additional parameters were set up such as compliance<br />

with factors compromising the reliability of measurements,<br />

according to Alvarez & Yoshimoto (2004).<br />

Initially, the i<strong>de</strong>ntification of main sound sources that<br />

generate discomfort to users was un<strong>de</strong>rtaken and 13 and<br />

10 points of outsi<strong>de</strong> and insi<strong>de</strong> measurements were set<br />

up, respectively, as well as the measurement times: during<br />

<strong>da</strong>ytime, with higher levels resulting from the operation<br />

of several types of equipment, and during night time,<br />

with lower sound levels. The equipment used was a digital<br />

sound level meter with calipers (Extech TM ) set at weighing<br />

A. This setting has been justified in several studies showing<br />

that sound levels measured in dB(A) are the closest to the<br />

perceptual characteristics of human hearing (Grandjean &<br />

Kroemer, 2005).<br />

For the analysis of collected <strong>da</strong>ta, the mean and<br />

stan<strong>da</strong>rd <strong>de</strong>viation values of the noise levels measured<br />

at each point were calculated in or<strong>de</strong>r to show their<br />

<strong>de</strong>gree of variability. Then, the analysis of <strong>da</strong>ta for every<br />

environment was performed observing the variation<br />

during different collection <strong>da</strong>ys and during two periods,<br />

<strong>da</strong>ytime and night time, as well as active noise sources<br />

at the time of the measurements. This was followed by<br />

acoustic mapping of EACF according to the comfort levels<br />

established by stan<strong>da</strong>rd NBR 10152 (ABNT, 1987b). The<br />

<strong>da</strong>ta of the stan<strong>da</strong>rd and measurement were overlapping<br />

and their differences were noted, and subsequently possible<br />

correlations with physical, physiological and psychological<br />

effects from noise on human beings were carried out.<br />

Results<br />

During the period of measurement, the main noise sources<br />

i<strong>de</strong>ntified in the inner environments of the Coman<strong>da</strong>nte<br />

Ferraz Antarctic Station (EACF) were the electric power<br />

generators, located in the Machinery Room and Garage,<br />

and the air compressors of the Aquariums and Carpentry.<br />

In the outdoor environment, the noisiest were the vehicles –<br />

tractor and boat – in operation, including all night on one<br />

of the <strong>da</strong>ys.<br />

The largest variations in noise levels throughout the study<br />

occurred on <strong>da</strong>ys when two electric power generators had<br />

been replaced, mainly at point B, in the Machinery Room,<br />

where the noise reduction was more significant in the <strong>da</strong>ys<br />

following the change of the electric power generators.<br />

It was also found that the operational equipment, such<br />

as generators, compressors and trash incinerator led to<br />

alterations in the noise level not only in the measurement<br />

environments, but also in the adjacent ones too.<br />

It is noteworthy that the interior of the cabins was not<br />

consi<strong>de</strong>red, since the settings of reduced dimensions did not<br />

allow using the methodological <strong>de</strong>terminants required by<br />

specific stan<strong>da</strong>rd to use the sound level meter. However, the<br />

assessment of environment is consi<strong>de</strong>red to be of essential<br />

importance as negative effects of noise interferes with the<br />

length and quality of sleep, in addition acts indirectly leading<br />

to <strong>de</strong>crease of the <strong>da</strong>ily performance of the human being,<br />

mainly in tasks requiring concentration. The collected <strong>da</strong>ta<br />

were systematized and appear in the Figure 1.<br />

Discussion<br />

When the <strong>da</strong>ta related to <strong>da</strong>ytime and night time periods<br />

of measurement were compared, reduced noise mean<br />

value was found at some points. In general, the places of<br />

measurement are passage environments (points A, Garage;<br />

B, Machinery Room; C, Old Garage; E, Triage Room), except<br />

the points D (Carpentry) and E (Screening Room), where<br />

the standing time was lower.<br />

In these places, the inner measurement of the environment<br />

could be ascertained, at which point E the mean noise levels<br />

during <strong>da</strong>ytime and night time were 64.44 dB(A) and<br />

54.73 dB(A), respectively, noting a <strong>de</strong>crease of 9.01 dB(A)<br />

for the night time period. The stan<strong>da</strong>rd <strong>de</strong>viation values<br />

showed a range of 3.84 dB(A)/<strong>da</strong>ytime and 4.33 dB(A)/night<br />

time. The time of lou<strong>de</strong>r noise was during the measurement<br />

on December 12th, at 10 am, reaching 72 dB(A) when<br />

impact noise (from a hammer) occurred in the Carpentry.<br />

In or<strong>de</strong>r to a<strong>de</strong>quate this environment to a level<br />

consi<strong>de</strong>red comfortable, 40 dB(A), according to stan<strong>da</strong>rd<br />

NBR 10152 (ABNT, 1987a), it would be necessary to reduce<br />

this average to 24.44 dB(A)/<strong>da</strong>ytime and 14.73 dB(A)/night<br />

time. In or<strong>de</strong>r to achieve the level consi<strong>de</strong>red acceptable, 50<br />

dB(A), it would be necessary to reduce 14.44 dB(A)/<strong>da</strong>ytime<br />

and 4.73 dB(A)/night time. However, by applying the NR 15<br />

(Brasil, 1978) the standing time in this environment could be<br />

an 8-hour working <strong>da</strong>y, although it is already characterized<br />

as a situation of discomfort.<br />

In the Carpentry (point D), higher sound level also was<br />

found on December 12 th , at 10 am, recording 89.9 dB(A).<br />

According to the mean of the environment of 72.33 dB(A),<br />

the standing time insi<strong>de</strong> it also could be an 8-hour working<br />

<strong>da</strong>y, as reported in the NR 15, in a discomfort situation.<br />

Murgel (2009) have reported that exposure to noise levels<br />

above 70 dB(A) may lead to sensitive neuropsychological<br />

changes whose symptoms are increased heart and<br />

respiratory rates and high blood pressure, effects from an<br />

alert and <strong>de</strong>fense status to which the body is subjected.<br />

Above this level the body stress increases, and at around<br />

100 dB(A) there may be immediate loss of the hearing<br />

(Souza, 1992).<br />

In the remaining points, the significance for analysis was to<br />

confirm whether the indoor working and rest environments<br />

needing less noise level and having higher standing time<br />

were in accor<strong>da</strong>nce with the recommen<strong>da</strong>tions of stan<strong>da</strong>rd<br />

NBR 10152, such as the Cabins, Ward, Department of<br />

Communication, Library, Audio and Vi<strong>de</strong>o Room and<br />

Laboratories. As the EACF is a Scientific Station, one aspect<br />

consi<strong>de</strong>red is that its environments are used both during<br />

<strong>da</strong>ytime and night time periods, thus the levels should be<br />

compatible in both situations, since in these places the use<br />

of alternatives to protect the user against noise are difficult,<br />

such as using earplugs and controls to reduce the exposure<br />

time, are hampered.<br />

By observing the measurement points next to the Cabins<br />

(9, 10, 11 e 12), at point 9 a <strong>de</strong>crease of 7.04 dB(A) during the<br />

night time period was found; at points 10 and 11 an increase<br />

of 2.45 dB(A) and 0.85 dB(A), respectively were found; and<br />

at point 12 a <strong>de</strong>crease of 1.62 dB(A) was noted. In or<strong>de</strong>r<br />

to a<strong>de</strong>quate to the level of 35 dB(A), the level consi<strong>de</strong>red<br />

comfortable according to NBR 10152 (ABNT, 1987b), would<br />

require sealing materials to isolate the external noise during<br />

the <strong>da</strong>ytime period, reducing its level of transmission into<br />

the environment in 28.17 dB(A), 20.40 dB(A), 23.00 dB(A)<br />

and 21.57 dB(A), respectively at points 9, 10, 11, and 12. In<br />

or<strong>de</strong>r to achieve the level of 40 dB(A), the level consi<strong>de</strong>red<br />

acceptable, would require a <strong>de</strong>crease of 23.17 dB(A), 15.40<br />

dB(A), 18.00 dB(A) and 16.57 dB(A), respectively.<br />

Hearing, being the first alert sense of the human being,<br />

is always active even during sleep and according to the<br />

World Health Organization (WHO, 1980), the effects of<br />

noise on sleep starts from 35 dB (A), thus beginning of<br />

alertness. Above the mentioned level <strong>de</strong>ep sleep time is<br />

reduced, in addition it extends beyond sleep time by a<br />

further 20 minutes for levels higher than 65 dB(A) and up<br />

to 10 minutes for levels up to 55 dB(A), according Murgel<br />

(2009). Thus, the importance of meeting the stan<strong>da</strong>rd is<br />

noted, mainly in the dormitory environments, in or<strong>de</strong>r to<br />

ensure <strong>de</strong>ep sleep, which is the most restorative sleep phase<br />

and which will allow the good performance of tasks on the<br />

following <strong>da</strong>y.<br />

In Laboratory and Library Rooms, which require<br />

intellectual work, the need to keep noise below 55 dB (A)<br />

is justified to avoid losses in productivity and the likelihood<br />

of errors in tasks requiring concentration and memory<br />

(Murgel, 2009).<br />

In environments where intelligible verbal communication<br />

is important, such as the Department of Communication<br />

and the Audio and Vi<strong>de</strong>o Room, it is recommen<strong>de</strong>d to keep<br />

the noise level up to 45 dB(A), so that the conversation<br />

be performed in a normal tone of voice. When the level<br />

increases to 55 dB (A) the speech recognition has become<br />

difficult, and when it reaches 65 dB (A) a higher vocal effort is<br />

required. The necessary reductions in the <strong>da</strong>ytime period in<br />

or<strong>de</strong>r to reach both the comfortable and the acceptable levels<br />

for theses environments to meet the stan<strong>da</strong>rd, respectively,<br />

would be: in the Department of Communication, point I,<br />

24.69 dB(A) and 19.69 dB(A); point J, 21.79 dB(A) and 16.79<br />

dB(A). In the Audio/Vi<strong>de</strong>o Room, point G, 35.24 dB (A)<br />

and 25.24 dB(A); point H, 27.98 dB(A) and 17.98 dB(A);<br />

point I, 24.69 dB(A) and 14.69 dB(A); point J, 21.79 dB(A)<br />

and 11.79 dB(A). For the night time period, the reductions<br />

to reach both the comfortable and acceptable levels would<br />

be: Department of Communication, point I, 23.20 dB(A)<br />

and 18.20 dB(A); point J, 19.39 dB(A) and 14.39 dB(A). In<br />

the Audio/Vi<strong>de</strong>o Room, point G, 35.04 dB(A) and 25.04<br />

dB(A), point H, 27.81 dB(A) and 17.81 dB(A); point I, 23.20<br />

dB(A) and 13.20 dB(A); point J, 19.39 dB(A) and 9.39 dB(A).<br />

Conclusion<br />

In or<strong>de</strong>r to measure the actual noise level from environments<br />

of the EACF the internal measurement of their rooms would<br />

be required, which was expected to occur in the summer of<br />

2012/2013. However, on 25 February, 2012, a fire <strong>de</strong>stroyed<br />

part of the EACF, creating discontinuity of all the studies.<br />

Thus, the <strong>da</strong>ta obtained and measured will serve mainly to<br />

aid in the preparation of the Reference Term that will gui<strong>de</strong><br />

the construction of new buildings that will comprise the<br />

EACF, standing out as <strong>de</strong>sirable the need for more research<br />

regarding the sealing materials of environments and their<br />

contribution to isolation of the sources of noise, whether<br />

outdoors or indoors. The application of questionnaires to<br />

users for subjective assessing of the noise that points out<br />

psychological changes, as well as physical evaluations to<br />

verify the hearing thresholds of the users and the time of<br />

exposure to noises with the aid of professionals from other<br />

fields of science also would complement this research.<br />

In environments directly analyzed, namely Carpentry<br />

and Screening Room, the mean noise levels showed<br />

differences with the stan<strong>da</strong>rds parameters; thus, in the<br />

future specific solutions should be applied to reduce the<br />

noise. In these cases the options are: to reduce the noise<br />

at source, to diminish the noise in the environment<br />

where the source is located, to <strong>de</strong>crease the noise between<br />

the environment where it is produced and the other<br />

environment, or to minimize the noise at the own hearing<br />

organ. In environments indirectly analyzed, namely<br />

Cabins, Ward, Department of Communication, Library,<br />

Laboratories, and Audio/Vi<strong>de</strong>o Room, further research<br />

of construction materials is recommen<strong>de</strong>d to achieve the<br />

correct measurement of indoor noise level.<br />

Acoustic mapping is an important tool that can help in<br />

<strong>de</strong>sign <strong>de</strong>cisions such as the location of noisy equipment,<br />

specification of less noisy equipment, use of materials with<br />

acoustic qualities and use of materials that do not require<br />

maintenance with noisy equipment.<br />

Abstract: The study of indoor air quality has recently increased since most of the time people are in closed spaces. A large contribution<br />

to the emission of indoor pollutants is originated from human activities and building processes. Volatile Organic Compounds,<br />

mainly from the al<strong>de</strong>hy<strong>de</strong>s group are present in most parts of new flooring and furnishing, furthermore, these substances have<br />

adverse effects on human health. This study investigated the al<strong>de</strong>hy<strong>de</strong> concentration using passive samplers in many places of<br />

Coman<strong>da</strong>nte Ferraz Brazilian Antarctic Station. The results showed compounds like formal<strong>de</strong>hy<strong>de</strong>, acrolein, acetal<strong>de</strong>hy<strong>de</strong> and<br />

hexanal<strong>de</strong>hy<strong>de</strong> with significant concentration indoors, in that formal<strong>de</strong>hy<strong>de</strong> concentration in new rooms excee<strong>de</strong>d the gui<strong>de</strong>lines<br />

of The World Health Organization. Therefore, these results show the need for monitoring these compounds as well as the study<br />

of the sources of emission.<br />

Keywords: al<strong>de</strong>hy<strong>de</strong>s, indoor air quality, passive sampling, building materials<br />

Introduction<br />

Over the last half-century there have been major changes<br />

in building materials, personal habits and consumer<br />

products used indoors: composite-wood, synthetic carpets,<br />

polymeric flooring, foam cushioning, plastic items, scented<br />

cleaning agents, time spent indoors, air- conditioning and<br />

others have become ubiquitous (Weschler, 2008). These<br />

new habits and new chemical substances in indoor spaces<br />

other than architectural typology can intensify low rates<br />

of air exchange and contribute significantly to indoor air<br />

quality of a building.<br />

Studies have shown that building materials are responsible<br />

for about 40% of the level of emissions of indoor pollutants,<br />

with significant amounts of emission coming from Volatile<br />

Organic Compounds (VOCs) present in these materials<br />

(Missia et al., 2010). Among compounds, al<strong>de</strong>hy<strong>de</strong>s are of<br />

particular interest due to their impact on health and because<br />

they are mainly domestic environment pollutants.<br />

Most studies of al<strong>de</strong>hy<strong>de</strong>s are related to formal<strong>de</strong>hy<strong>de</strong>,<br />

classified in Group 2A by the International Agency of<br />

Research on Cancer due to its carcinogenicity. It has an effect<br />

on health <strong>de</strong>pending on environment levels. The olfactory<br />

<strong>de</strong>tection threshold is 60 µg/m³ and varies according to<br />

each person; it can cause hea<strong>da</strong>ches, nausea or dizziness. It<br />

can also cause mucous irritations as a result of exposure at<br />

levels from 10 µg/m³ and chronic exposure of formal<strong>de</strong>hy<strong>de</strong><br />

can induce conjunctivitis, pharyngitis, laryngitis, bronchitis<br />

or coughing (Clarisse et al., 2003). The World Health<br />

Organization recommen<strong>de</strong>d an exposure limited to<br />

100 µg/m³ for about 30 minutes to prevent long-term effects<br />

on human health including cancer (WHO, 2010). It is known<br />

that other specific al<strong>de</strong>hy<strong>de</strong>s like acrolein and acetal<strong>de</strong>hy<strong>de</strong><br />

also cause irritation of eyes, skin and mucous membranes of<br />

the human respiratory tract. The acetal<strong>de</strong>hy<strong>de</strong>, for example,<br />

has been classified as B2, as a likely human carcinogen of<br />

low carcinogenic hazard (Weng et al., 2009).<br />

The purpose of our work is to i<strong>de</strong>ntify and quantify<br />

VOCs of the al<strong>de</strong>hy<strong>de</strong> group insi<strong>de</strong> Coman<strong>da</strong>nte Ferraz<br />

Antarctic Station located in Admiralty Bay, King George<br />

178 | Annual Activity Report 2011


Island, South Shetlands archipelago. The results will<br />

evaluate the contribution of pollution sources from human<br />

activities and building materials, as Antarctica is a natural<br />

environment without the anthropogenic interference of<br />

urban centers. Moreover, a large time spent indoors at the<br />

Antarctica Station with probable indoor sources of emission<br />

is a motivation of studies related to health and Sick Building<br />

Syndrome (SBS).<br />

Materials and Methods<br />

The experiment was carried out from January 14 th to<br />

February 3 rd in the Coman<strong>da</strong>nte Ferraz Antarctic Station.<br />

The sampler spaces were selected because of their high usage<br />

with likely indoor pollution sources.<br />

The study consi<strong>de</strong>red ten indoor spaces. Three spaces of<br />

general use: living room, library and gym. Three bedrooms:<br />

two for two people and the third being the Arsenal<br />

accommo<strong>da</strong>tion (twelve people). Four work spaces: kitchen,<br />

carpentry, “Ferrazão” and a space near the incinerator. The<br />

kitchen was located insi<strong>de</strong> the main body of the station and<br />

the other workspaces were located outsi<strong>de</strong> the main body of<br />

the station, without a heating system, but with roof cover.<br />

In general, the mean indoor temperature of the spaces is<br />

22 °C and the relatively humidity around 33%. In the outsi<strong>de</strong><br />

working area the mean temperature is 9 °C and the relatively<br />

humidity, 26%. The space distribution samplers were placed<br />

according to Figure 1.<br />

Al<strong>de</strong>hy<strong>de</strong>s were sampled using Radiello® Al<strong>de</strong>hy<strong>de</strong>s<br />

Samplers (Fon<strong>da</strong>zione Salvatore Maugeri, 2011). These<br />

are passive samplers that are impregnated cartridges with<br />

2,4-dinitrophenyhydrazones adsorbent in a cylindrical<br />

body. The samplers were left about 3, 6 or 7 <strong>da</strong>ys according to<br />

manufacturer’s recommen<strong>da</strong>tion and the potential pollution<br />

of space. A total of 16 samplers and four blanks (samplers<br />

that were not exposed to the environment in or<strong>de</strong>r to <strong>de</strong>tect<br />

back noise or transport contamination) were placed. The<br />

samplers were exposed at a stan<strong>da</strong>rd height of 1.5 m (The<br />

European Stan<strong>da</strong>rd, 2006), which is the medium height of<br />

human breathing, and when possible in the space centre<br />

(Figure 2).<br />

A questionnaire was also ma<strong>de</strong> for each space,<br />

summarizing the present building material, the human<br />

activities during the sampling and other pollution sources.<br />

After exposure the cartridge was set in a specific and<br />

i<strong>de</strong>ntified glass tube and stored in the refrigerator (below<br />

4 °C) in the station to be transported in the same conditions<br />

to Brazil. In Brazil the adsorbent was put into a tube with<br />

2 mL of acetonitrile, and then it was closed and sonicated<br />

for 30 minutes. The final solution of each sampler was then<br />

(Fon<strong>da</strong>zione Salvatore Maugeri, 2011).<br />

Sampler analyses were performed by reverse-phase High<br />

Performance Liquid Chromatography (HPLC) using an UV<br />

<strong>de</strong>tector operated at a wavelength of 365 nm. The hydrazone<br />

separation was carried out on Agilent Technologies C18<br />

column (250 × 4.6 mm, 5 µm) associated with a precolumn.<br />

Two solutions were used for gradient elution: solution A<br />

contained water and solution B contained acetonitrila.<br />

Starting conditions: 40% of solution A and 60% of solution<br />

B for seven minutes, then a linear gradient was applied over<br />

20 minutes with 100% of solution B. After, between 21 and<br />

30 minutes 40% of solution A and 60% of solution B were<br />

applied again. The eluent flowing rate was 2.0 mL/min, the<br />

temperature was constant in 37 °C (Collins, 2007, modify).<br />

The <strong>de</strong>termination of the carbonyls was done according<br />

to the Environment Protect Agency methodology (EPA,<br />

1999). The al<strong>de</strong>hy<strong>de</strong>s quantification was done using a<br />

stan<strong>da</strong>rd hydrazone solution TO11/IP-6A (cod. 47285-<br />

U - Supelco, Bellefonte PA, USA). Both <strong>de</strong>tection and<br />

quantification limits were calculated for all samplers<br />

according to the gui<strong>de</strong> for vali<strong>da</strong>tion of analytical and<br />

bioanalytical methods (ANVISA, 2003).<br />

Results<br />

Figure 3 shows the al<strong>de</strong>hy<strong>de</strong>s concentration found for each<br />

sampler place. The average concentration of total indoor<br />

air carbonyls was 196.06 µg/m³. The acrolein was the<br />

most abun<strong>da</strong>nt carbonyls in most air samples, followed by<br />

acetal<strong>de</strong>hy<strong>de</strong>, formal<strong>de</strong>hy<strong>de</strong>, hexanal<strong>de</strong>hy<strong>de</strong>, butyral<strong>de</strong>hy<strong>de</strong>,<br />

pentanal<strong>de</strong>hy<strong>de</strong>, isopentanal<strong>de</strong>hy<strong>de</strong>, propinal<strong>de</strong>hy<strong>de</strong><br />

and benzal<strong>de</strong>hy<strong>de</strong> with the average value of respectively<br />

44.41 µg/m³; 38.33 µg/m³; 33.68 µg/m³; 30.88 µg/m³;<br />

21.80 µg/m³; 9.01 µg/m³; 8.45 µg/m³; 8.30 µg/m³ and<br />

1.21 µg/m³. Acrolein, acetal<strong>de</strong>hy<strong>de</strong>, formal<strong>de</strong>hy<strong>de</strong> and<br />

hexanal<strong>de</strong>hy<strong>de</strong> accounted for respectively 22%, 20%, 17%<br />

and 16% of total al<strong>de</strong>hy<strong>de</strong>s indoor air.<br />

The acetal<strong>de</strong>hy<strong>de</strong> concentration was higher in the<br />

living room (70.02 µgm³; 81.28 µg/m³; 58.13 µg/m³) and<br />

kitchen (70.63 µg/m³; 80.22 µg/m³; 108.86 µg/m³) than<br />

other places. The formal<strong>de</strong>hy<strong>de</strong> concentration was higher<br />

in the bedrooms (100.93 µg/m³ for bedroom 10 and<br />

131.67 µg/m³ for bedroom 21). Bedroom 21 had a significant<br />

concentration of hexanal<strong>de</strong>hy<strong>de</strong> too (97.52 µg/m³) contrary<br />

to the concentration for bedroom 10 (13.58 µg/m³). In<br />

the library the main compounds found were: acrolein<br />

(61.84 µg/m³; 58.54 µg/m³), formal<strong>de</strong>hy<strong>de</strong> (36.10 µg/m³;<br />

39.48 µg/m³), acetal<strong>de</strong>hy<strong>de</strong> (20.66 µg/m³; 24.1152/m³) and<br />

hexanal<strong>de</strong>hy<strong>de</strong> (18.76 µg/m³; 19.11 µg/m³).<br />

The least concentration from all the compounds was found<br />

in the gym, “Ferrazão”, carpentry and incinerator. The<br />

concentration of propinal<strong>de</strong>hy<strong>de</strong> and benzal<strong>de</strong>hy<strong>de</strong> was<br />

found in minor importance, similar to the concentration<br />

found by Clarisse et al. (2003).<br />

Discussion<br />

Levels of acrolein, acetal<strong>de</strong>hy<strong>de</strong> and formal<strong>de</strong>hy<strong>de</strong> are the<br />

most studied in relation to indoor air quality (Andra<strong>de</strong> et al.,<br />

2002). Studies related to heated cooking oils produce<br />

consi<strong>de</strong>rable amounts of acrolein. Cooking is an important<br />

source of indoor acrolein. In addition it is also formed by<br />

the oxi<strong>da</strong>tion of voltatic organic carbon species released<br />

by building materials (Seaman et al., 2009). The abun<strong>da</strong>nt<br />

concentration of acrolein found in the cartridges in our<br />

work can be explained by the activity of frying in a closed<br />

building like the Antarctic Station. Some spaces like living<br />

room and kitchen sometimes have open windows but the<br />

bedrooms and the library were closed most of the time<br />

resulting in higher concentration.<br />

There are three main sources of acetal<strong>de</strong>hy<strong>de</strong>: cleaning<br />

agents, people and building materials. The higher<br />

acetal<strong>de</strong>hy<strong>de</strong> concentration in the kitchen and living room<br />

can be related to a constant use of cleaning agents in this<br />

place. In the Brazilian Antarctic Station the living room<br />

and kitchen are cleaned about four times a <strong>da</strong>y. Moreover<br />

these rooms have a large number of people during breakfast,<br />

lunch, dinner and parties. Andra<strong>de</strong> et al. (2002) stated that<br />

the main source of acetal<strong>de</strong>hy<strong>de</strong> in human organism is<br />

the metabolism of ethanol. Part of this concentration can<br />

also result from wood products such as doors, walls and<br />

plywood floor (Marchand et al., 2005) found in the living<br />

room of the station.<br />

Many studies reported that formal<strong>de</strong>hy<strong>de</strong> is released by<br />

various building materials mainly wood-pressed products<br />

and the levels are significantly greater in new buildings<br />

(Missia et al., 2010). The rooms that had the highest<br />

concentration for formal<strong>de</strong>hy<strong>de</strong> were the bedrooms. The<br />

highest concentration was found in bedroom 21 probably<br />

because it is one of the most recently built bedrooms of<br />

the station. It was first utilized in this campaign. There was<br />

laminated wood flooring and composite-wood furnishings.<br />

Bedroom 10 had the same building materials but it was<br />

ol<strong>de</strong>r, although this bedroom showed significant levels of<br />

Science Highlights - Thematic Area 4 |<br />

181


formal<strong>de</strong>hy<strong>de</strong> concentration too. Despite many studies<br />

associated VOCs concentration in new buildings, little is<br />

known about the behavior of these indoor compounds after<br />

a certain period of time (Clarisse et al., 2003).<br />

It is important to note that the formal<strong>de</strong>hy<strong>de</strong><br />

concentration in bedroom 21 for an exposure of seven <strong>da</strong>ys<br />

was greater than the limit of the World Health Organization,<br />

which is 100 µg/m³ for 30 minutes exposition. Lower values<br />

were found in other studies. Missia et al. (2010) found<br />

5.8‐62.6 µg/m³ insi<strong>de</strong> three buildings with different ages<br />

and different ventilation systems and Weng et al. (2009)<br />

found a mean concentration for formal<strong>de</strong>hy<strong>de</strong> of 90.61 µg/<br />

m³ insi<strong>de</strong> supermarkets, stores and cinemas.<br />

Bedroom 21 showed the highest hexanal<strong>de</strong>hy<strong>de</strong><br />

concentration compared to bedroom 10, which had the<br />

same building materials. This is due to the new plywood<br />

sub floor in bedroom 21, which is a probable major hexanal<br />

source, this compound is observed in abun<strong>da</strong>nce in new<br />

spaces with less than two years of construction using<br />

this material (Marchand et al., 2005). The library showed<br />

significant levels of formal<strong>de</strong>hy<strong>de</strong> and acetal<strong>de</strong>hy<strong>de</strong>. A<br />

variety of VOCs are known to be emitted from paper and<br />

other cellulose-based materials during <strong>de</strong>gra<strong>da</strong>tion, this<br />

inclu<strong>de</strong>s the al<strong>de</strong>hy<strong>de</strong>s as formal<strong>de</strong>hy<strong>de</strong> and acetal<strong>de</strong>hy<strong>de</strong><br />

(Fenech et al., 2010).<br />

The least concentration of al<strong>de</strong>hy<strong>de</strong>s was shown in the<br />

places with greater air exchange, such as the gym, where<br />

the windows are frequently opened, and also in “Ferrazão”,<br />

carpentry and incinerator that are located outsi<strong>de</strong> the main<br />

body of the station.<br />

Conclusion<br />

Compounds such as acrolein, formal<strong>de</strong>hy<strong>de</strong>, acetal<strong>de</strong>hy<strong>de</strong><br />

and hexanal<strong>de</strong>hy<strong>de</strong> make a significant contribution to<br />

indoor air quality. Regarding building material, it is very<br />

likely that the pressed wood used in the floor, walls and<br />

furnishing present in the Antarctic Brazilian Station are<br />

responsible for many emissions of these pollutants. The<br />

formal<strong>de</strong>hy<strong>de</strong>, that is <strong>da</strong>ngerous to health, showed higher<br />

levels in bedrooms mainly the new bedroom. Furthermore,<br />

the human activities such as cooking and cleaning agents<br />

were also responsible for some of the compounds <strong>de</strong>tected.<br />

This may indicate the need to review the building materials<br />

and indoor ventilation strategy, as an important instrument<br />

of control of the sources of pollutant emissions.<br />

Abstract: With the purpose of strengthening and formalizing the fulfillment of the principles relating to the Antarctic environment<br />

protection established in the Madrid Protocol, an Environmental Management System certifiable to ISO14001:2004 was set up at<br />

the Brazilian Antarctic Scientific Station “Coman<strong>da</strong>nte Ferraz” (EACF, from now on), to limit the negative environmental impacts.<br />

The internal audit of the Environmental Management System of EACF was conducted between December 2011 and January<br />

2012, to verify the compliance of facilities and activities of the EACF in relation to the requirements established by the stan<strong>da</strong>rd,<br />

aiming at the certification audit, scheduled for November 2012.The audit was conducted through interviews, <strong>da</strong>ta collection,<br />

observations and analysis of documents and records, and then the findings were discussed and the non-conformities i<strong>de</strong>ntified.<br />

The level of compliance of the EACF with reference to the requirements of the stan<strong>da</strong>rd ISO 14.001:2004 came to 86,2%. The<br />

conclusion arising from the findings is that the organization is in a situation of partial compliance with the requirement staken<br />

as a reference and scope of the environmental audit.<br />

Introduction<br />

The concern with the quality of the environment is not new,<br />

but it was in the late twentieth century that it was finally<br />

inserted in the plans of the governments of many countries<br />

and different segments of society such as among economists,<br />

scientists and as part of technological concerns.<br />

In this same period, there was an advance in terms<br />

of institutionalizing a new political world aimed at<br />

environmental responsibility and sustainable <strong>de</strong>velopment,<br />

result of a more critical analysis of the relationship between<br />

society and the environment that goes beyond geographical<br />

and temporal boun<strong>da</strong>ries.<br />

The organizational responsibility of the environment<br />

stopped being only a man<strong>da</strong>tory feature to become a<br />

voluntary action, exceeding the expectations of society.<br />

Antarctica is the continent whose natural conditions<br />

are most preserved, where environmental impacts can<br />

cause irreversible consequences and, for this reason, it<br />

is appropriate to be above the legal requirements. Given<br />

this, the Environmental Management System (EMS from<br />

now on) goes beyond being just a preventive strategy to<br />

constitute a need in itself, this because, environmental<br />

quality requires at least a more rational use of inputs, an<br />

aspect of great importance when we speak of supply logistics<br />

for Antarctic stations.<br />

In or<strong>de</strong>r that the commitments ma<strong>de</strong> by Brazil for the<br />

international community are met with an emphasis on<br />

preventive attitu<strong>de</strong>s, during the years 2010 and 2011 the<br />

certifiable EMS ISO 14001:2004 was set up at EACF, which<br />

184 | Annual Activity Report 2011


had the objective of strengthening and formalizing the<br />

fulfillment of the principles relating to protection of the<br />

Antarctic environment established in the Madrid Protocol,<br />

to limit the negative environmental impacts in the Antarctic<br />

environment.<br />

Indispensable to the EMS, the internal audit was<br />

conducted between December 2011 and January 2012<br />

with the objective of verifying the compliance of EACF<br />

installations and activities with requirements established<br />

by ISO 14001:2004 aiming at the certification audit, which<br />

was scheduled for November 2012.<br />

It was observed with the internal audit that the<br />

organization is in a situation of partial conformity with<br />

the requirement staken as a reference and the scope of the<br />

environmental audit, reaching 86.2% of compliance with<br />

the requirements of ISO14001:2004.<br />

It is noteworthy that, the EMS of EACF will not obtain a<br />

certification audit pass, because on February 25th, after the<br />

internal audit, a serious acci<strong>de</strong>nt occurred with the outbreak<br />

of fire at EACF, <strong>de</strong>stroying it completely and causing the<br />

<strong>de</strong>aths of two Brazilian military.<br />

Materials and Methods<br />

The internal environmental audit was carried out to verify<br />

the compliance of EACF installations and activities, in<br />

relation to the requirements of ISO 2004, which provi<strong>de</strong>s<br />

for Environmental Management System - Specification with<br />

Gui<strong>da</strong>nce for Use (ISO 14001, 2004).<br />

The internal audit process was applied in all EACF<br />

installations and activities that were covered by the EMS.<br />

The focus of the internal audit concerned the processes<br />

that have activities with aspect and impact significance and<br />

so have specific procedures <strong>de</strong>veloped in the EMS of EACF.<br />

The steps of the audit were conducted in modules that<br />

had activities contemplated in the EMS of EACF. Firstly the<br />

objective and scope of the audit was <strong>de</strong>fined, and then the<br />

documents requested for preliminary analysis.<br />

After the preliminary analysis of the documents, the<br />

preparation stage for the audit was initiated, which <strong>de</strong>fined<br />

the Audit Plan, for this, the audit team was selected and<br />

trained, and finally the work documentation, the check-list<br />

and audit protocols were <strong>de</strong>veloped.<br />

The checklist was <strong>de</strong>veloped and used to facilitate and<br />

ensure that the observations and search of non-compliances<br />

were conducted on all the EACF modules contemplating<br />

all the procedures established in the EMS documentation.<br />

The audit team consisted of the group-base of Brazilian<br />

Navy and researchers from the National Institute of<br />

Environmental Science and Technology of Antarctic<br />

Environmental Research (INCT-APA).<br />

With the documents and team ready, the audit was<br />

initiated, first un<strong>de</strong>rtaking the opening meeting, which<br />

presented the objective and scope, the audit team, the timing<br />

of the audit and the gui<strong>de</strong>s who accompanied the audit by<br />

the audited.<br />

The audit was conducted through interviews, <strong>da</strong>ta<br />

collection, observations and analysis of documents and<br />

records, and then the findings were discussed and the nonconformities<br />

<strong>de</strong>fined.<br />

The audit report was presented to the management<br />

representative, to show the collected <strong>da</strong>ta and the<br />

conclusions of the audit, and so, confirm the proposed plans<br />

of action or suggest other strategies for the correction of<br />

non-conformities.<br />

Results<br />

The completion of the internal audit counted with the full<br />

support of everyone in the EACF, especially the members<br />

of Brazilian Navy, sometimes acting like internal auditors<br />

or like support team to achieve this important stage of EMS<br />

of the EACF.<br />

With the realization of the Environmental Audit<br />

insi<strong>de</strong> the installations and processes of the organization,<br />

some evi<strong>de</strong>nce that formed the basis for findings was<br />

collected, which indicates the need for corrective and<br />

preventive actions in or<strong>de</strong>r to fully attend the established<br />

recommen<strong>da</strong>tions set by <strong>de</strong>fault reference adopted.<br />

As a summary of the findings we have ma<strong>de</strong> the<br />

i<strong>de</strong>ntification of five non-conformities of great importance,<br />

non-conformity with less significance and ten observations.<br />

The conclusion resulting from the findings is that the<br />

organization is in a situation of Partial Compliance with<br />

the requirements taken as a reference and scope of the<br />

environmental audit.<br />

Figure 1. Requirements of ISO 14.001:2004.<br />

Grouping the results obtained for each requirement of<br />

ISO 14.001:2004 in applying the evaluation tool allowed the<br />

results shown in Figure 1.<br />

Overall, the level of atten<strong>da</strong>nce of EACF in reference to<br />

the requirements of the ISO 14.001:2004 was 86.2%, where<br />

the principle “Environmental Policy” was the only one<br />

which achieved 100% of compliance.<br />

Discussion<br />

By reason of non-registration of new activities with potential<br />

impact on the environment and no clear <strong>de</strong>finition of<br />

the plan presented at the Expedition XXIX about the<br />

objectives, the principle of “planning” which involves items<br />

Environmental Aspects, Legal Requirements and Objectives,<br />

Targets and Programs reached a level of 80% compliance.<br />

The highest level of compliance was observed in the<br />

requirements referred to “Implementation and Operation”<br />

at 88%: Resources, roles, responsibilities and authorities<br />

(93%), Competence, training and awareness (100%),<br />

Communication (80%), Documentation (92%), Control<br />

of Documents (100%), Operational Control (90%) and<br />

Emergency Preparedness and Response, however, the latter<br />

was the item with the lowest atten<strong>da</strong>nce requirements (60%),<br />

special attention should be given to the implementation of<br />

corrective actions related to it.<br />

The group of items “Monitor and Measure” reached a<br />

level of compliance with the requirements of 83%, requiring<br />

corrective actions, in relation to registration and up<strong>da</strong>ting<br />

procedures adopted in EACF.<br />

Finally, the principle of “Review and Improvement”<br />

scored the second lowest compliance with the requirements<br />

of the stan<strong>da</strong>rd, 80%, due to the administrative disputes<br />

involving EMS of EACF.<br />

Conclusions<br />

Some observations have resulted in a<strong>da</strong>pting the EMS<br />

documents of EACF when the way the activity was<br />

performed was more appropriate or more applicable to<br />

the reality of the Antarctic environment, otherwise, when<br />

non-conformities were i<strong>de</strong>ntified, the best way to solve them<br />

was sought through discussions with stakehol<strong>de</strong>rs in the<br />

186 | Annual Activity Report 2011


area, or by bibliographic research, resulting in the proposed<br />

recommen<strong>da</strong>tions for each finding.<br />

Special attention on the part of the organization with<br />

respect to major non-conformities mentioned in the report<br />

was recommen<strong>de</strong>d, noting that the internal audit function<br />

is to check the pending items and record them properly,<br />

being the Chief of EACF, as management representative,<br />

the responsible for reporting and performing periodic<br />

requests for PROANTAR (Brazilian Antarctic Program)<br />

based also on the internal audit report, with the support<br />

of the coordinator of internal audit, Sub-Chief of EACF.<br />

Abstract: Antarctic soils are un<strong>de</strong>r constant risks of oil contamination due the presence of scientific stations. Bioremediation is<br />

the best choice for their recovery. However, before taking the initiative, it is important to test their effect on hydrocarbon <strong>de</strong>pletion<br />

and microorganisms. Furthermore, it is important to search for hydrocarbon <strong>de</strong>gra<strong>de</strong>rs and bioindicators for monitoring. Our<br />

studies showed that the low concentration of N may be causing the recalcitrance of the hydrocarbons in the soil. The microbial<br />

characterization revealed alteration of structure and low diversity of the microbial communities in the diesel-polluted soils. The<br />

results of an ex situ microcosm experiment revealed <strong>de</strong>pletion of the hydrocarbons content due the aeration and the application<br />

of N fertilizer, as well as effects un<strong>de</strong>r the microbial communities. An in situ microcosm experiment with the application of N<br />

fertilizer and oil-<strong>de</strong>gra<strong>de</strong>r bacterial species previously isolated confirmed the changes un<strong>de</strong>r the microbial community. However,<br />

it is important to point out that the impact of the fertilizer un<strong>de</strong>r microbial community is lower than the oil impact. The present<br />

<strong>da</strong>ta provi<strong>de</strong>s information that allows us to propose the appropriate methodology that can be applied in the area of the Brazilian<br />

Antarctic Station for the bioremediation process. In addition, to provi<strong>de</strong> information that allows us to propose an appropriate<br />

action plan using better recommen<strong>de</strong>d materials (e.g. type and dose of fertilizer; stock of consortia of <strong>de</strong>gra<strong>de</strong>rs strains) that will<br />

be available for immediate use in the case of new contaminations due to fuel spills in the new Brazilian Antarctic Station.<br />

Introduction<br />

Since the installation of scientific stations, Antarctic soils<br />

are un<strong>de</strong>r constant risk of fuel spills, especially due to the<br />

leaking of tanks, diesel transference and vehicle refueling<br />

(Aislabie et al., 2004). Anthropogenic activities like these<br />

spills can <strong>da</strong>mage the equilibrium of the <strong>de</strong>licate Antarctic<br />

environments, which used to possess the last remaining<br />

pristine zones on Earth (Reinhardt & Van Vleet 1986;<br />

Delille et al., 2004).<br />

In some cases, the attempt to cleanup can be ma<strong>de</strong><br />

using physical and chemical methods. However, for the<br />

Antarctic environments this is not so simple. Displacement<br />

of the machinery necessary for the application of physical<br />

methods would be very expensive, whereas the application<br />

of chemical methods would be <strong>da</strong>ngerous consi<strong>de</strong>ring<br />

the risks of additional environmental impacts. Therefore,<br />

bioremediation techniques have been consi<strong>de</strong>red an<br />

appropriate remediation technology for polar soils, being<br />

elatively more cost-effective and benign (Aislabie et al.,<br />

2006).<br />

Bioremediation techniques are based on the ability of<br />

some microorganisms to use the petroleum hydrocarbons<br />

as energy source (Alexan<strong>de</strong>r, 1994). The monitored natural<br />

attenuation is the best cost-effective choice to be applied in<br />

oil-polluted sites consi<strong>de</strong>ring the low-risk and presenting<br />

high rates of hydrocarbon <strong>de</strong>gra<strong>da</strong>tion. However, in polar<br />

soils the environmental conditions are suboptimal for<br />

bio<strong>de</strong>gra<strong>da</strong>tion (Aislabie et al., 2006). As for some soils out<br />

of the Polar Regions, a cause of hydrocarbon recalcitrance<br />

can be the <strong>de</strong>pletion of nutrients (especially N and P).<br />

An alternative to overcome this problem is the technique<br />

of biostimulation (Alexan<strong>de</strong>r, 1994), with the addition<br />

of fertilizers (e.g. N-P-K, MAP, DAP). However, these<br />

additions must be ma<strong>de</strong> carefully due the typical coarsetextured,<br />

low-moisture Antarctic soils because excess levels<br />

of fertilizers can inhibit hydrocarbon bio<strong>de</strong>gra<strong>da</strong>tion by<br />

<strong>de</strong>creasing soil water potentials (Aislabie et al., 2006). Other<br />

potential limitations for the activity of <strong>de</strong>gra<strong>de</strong>rs present<br />

in Antarctic soils inclu<strong>de</strong> low temperature and moisture,<br />

alkalinity and the potentially inhibitory effect of toxic<br />

hydrocarbons (Aislabie et al., 2006).<br />

Since the microorganisms are responsible for the<br />

<strong>de</strong>gra<strong>da</strong>tion of the hydrocarbons, it is very important to<br />

know their dynamics. According to Aislabie et al. (2006),<br />

studies have confirmed the presence of hydrocarbon<strong>de</strong>grading<br />

bacteria in polluted polar soils. Besi<strong>de</strong>,<br />

Luz et al. (2004, 2006) <strong>de</strong>monstrated that genes involved in<br />

hydrocarbons <strong>de</strong>gra<strong>da</strong>tion are present in the region of the<br />

Brazilian Antarctic Station (EACF). Additionally, it is known<br />

that the presence of oil can change the microbial diversity<br />

of Antarctic soils (Saul et al., 2005), and the knowledge of<br />

how it occurs may be important for bioindicators selection<br />

and further monitoring.<br />

The aim of this work was to characterize the soil<br />

properties, the extent of oil contamination and the microbial<br />

diversity of polluted and adjacent unpolluted soils of the<br />

Brazilian Antarctic Station. Beyond that, we aimed to test<br />

the impact of the application of different doses of fertilizer<br />

and previously selected <strong>de</strong>gra<strong>de</strong>r strains on <strong>de</strong>pletion of<br />

the hydrocarbons and changes in microbial community<br />

structure, to propose an efficient and sustainable alternative<br />

to minimize the oil pollution at EACF.<br />

Materials and Methods<br />

The sampling site is located on the front of the Brazilian<br />

Antarctic Station. The area close to the fuel tanks was<br />

subjected to a 20,000-L diesel spill in 1986. Previous<br />

analysis indicates that the reached soil contains variable<br />

concentrations of hydrocarbons in its subsurface (0.5-1.0 m)<br />

(<strong>da</strong>ta not shown). Subsurface staining and smell was evi<strong>de</strong>nt<br />

at several areas near the fuel tanks, indicating the presence<br />

of the hydrocarbons. Five superficial (1 m) soil samples were<br />

collected in triplicate in March 2010, during the Antarctic<br />

Summer. Three samples (1, 2 and 3) were collected in the<br />

oil-polluted area, whereas the other two samples (4 and 5)<br />

were collected in the oil-unpolluted area (Figure 1).<br />

The structure and diversity of the microbial communities<br />

of the soil samples are characterized using DGGE and SSU<br />

rDNA sequencing methods, respectively. To confirm the<br />

indigenous bacterial hydrocarbons <strong>de</strong>grading potential we<br />

performed a survey by PCR using specific primers for genes<br />

involved in <strong>de</strong>grading pathways.<br />

We performed ex situ and in situ microcosm<br />

bioremediation experiments to test the hydrocarbons<br />

<strong>de</strong>pletion and the impact of the treatments un<strong>de</strong>r the<br />

microbial communities. In the ex situ experimental doses<br />

of MAP fertilizers (biostimulation) were tested, whereas<br />

in the in situ microcosm a concentration of MAP plus the<br />

reintroduction of bacterial <strong>de</strong>gra<strong>de</strong>rs previously isolated<br />

from the contaminated soil (bioaugmentation) were tested.<br />

Results<br />

Nitrogen is present in extremely low levels in the soil<br />

samples collected in the Brazilian Antarctic Station before<br />

the fertilizer application. After two months since the<br />

application of the MAP fertilizer, the content of N became<br />

<strong>de</strong>tectable and ranged from 0.02 to 0.08 <strong>da</strong>g.kg –1 in the<br />

soil of the in situ microcosm experiment. Figure 2 shows<br />

the content of hydrocarbons of the original soil samples<br />

collected in oil-polluted (1 to 3) and oil-unpolluted (4 and<br />

5) areas and in oil-contaminated and oil-uncontaminated<br />

soils after the microcosm experiment. We can observe a<br />

linear <strong>de</strong>crease of hydrocarbons amount from point 1. After<br />

60 <strong>da</strong>ys of incubation, the hydrocarbons content <strong>de</strong>creased<br />

linearly until the treatment with 250 mg N.kg –1 .<br />

The DGGE analyses revealed that the collection points<br />

harbor different bacterial community structures since<br />

the repetitions of the triplicate or duplicate used always<br />

grouped together (Figure 3). The <strong>de</strong>ndrograms shows<br />

a strong ten<strong>de</strong>ncy of grouping due to the presence or<br />

absence of the hydrocarbon pollution. Furthermore, the<br />

DGGE analysis showed that the application of fertilizer<br />

and the reintroduction of bacterial <strong>de</strong>gra<strong>de</strong>rs influence the<br />

<strong>de</strong>termination of the structure of the bacterial communities<br />

of the soil (Figure 4). The SSU rDNA sequence results<br />

indicate a ten<strong>de</strong>ncy of higher bacterial and microeukaryotic<br />

diversity in the oil-uncontaminated soil (Figure 5),<br />

indicating a toxic effect of the diesel present in the area.<br />

The results from PCR amplification of key genes<br />

encoding bacterial hydrocarbon <strong>de</strong>gra<strong>da</strong>tion pathways<br />

showed that expected fragments of alkB gene, encoding for<br />

aerobic alkane <strong>de</strong>gra<strong>da</strong>tion, and bamA gene, the biomarker<br />

of aromatic <strong>de</strong>gra<strong>da</strong>tion by anaerobic bacteria, were found<br />

in both contaminated and uncontaminated soils. The Grampositive<br />

Discussion and Conclusion<br />

The recalcitrance of hydrocarbons in cold soils may be due<br />

characteristics as: low temperatures (Hai<strong>de</strong>r, 1999), lack of<br />

final electron acceptors (especially oxygen) (Johnsen et al.,<br />

2005), low nutrient concentrations or availability<br />

(especially N and P) (Aislabie et al., 2006), or the absence of<br />

microorganisms capable of using hydrocarbons as C source<br />

(Johnsen et al., 2005; Huesemann et al., 2002). Two of the<br />

cited factors must be contributing to the hydrocarbon<br />

recalcitrance in the soil of the Brazilian Antarctic Station:<br />

the nutrient content, especially Nitrogen, consi<strong>de</strong>ring<br />

the negligible amounts of this element in soil; and the<br />

lack of oxygen as electron acceptor, consi<strong>de</strong>ring that the<br />

polluted area remains un<strong>de</strong>r constant water logging and<br />

soil compression due the thaw of the upstream snow<br />

and the constant traffic of vehicles, respectively, which<br />

<strong>de</strong>creases the oxygen diffusion. The absence of <strong>de</strong>grading<br />

microorganisms not seems to be one recalcitrance factor<br />

consi<strong>de</strong>ring the positive results obtained in the PCR of<br />

the tested genes involved in the hydrocarbon <strong>de</strong>gra<strong>da</strong>tion.<br />

These results indicate that the microbial community of<br />

the oil-polluted soil of the Antarctic Brazilian Station is<br />

able to perform metabolic pathways of the hydrocarbon<br />

<strong>de</strong>gra<strong>da</strong>tion. An indication of the microorganisms<br />

participation in the hydrocarbon <strong>de</strong>pletion via <strong>de</strong>gra<strong>da</strong>tion<br />

is the dose-response effect observed with the application<br />

of the Nitrogen. The application of N at a rate between 125<br />

and 250 mg.kg –1 seems to be sufficient to promote further<br />

Abstract: The educational materials and activities presented arose from the need to publicize the results of research carried out by<br />

the National Institute of Science and Technology - Antarctic Environmental Research (INCT-APA) to basic education stu<strong>de</strong>nts and<br />

teachers and to the general public. The materials are inten<strong>de</strong>d to provi<strong>de</strong> a sample of those investigations and to present the work<br />

of researchers who are in Antarctica. The methodology consists in transcribing the scientific language of the published articles to<br />

an easier-to-un<strong>de</strong>rstand language for the school frequenter public and for those who visit exhibitions for scientific dissemination.<br />

Two exhibitions were held, the FAPERJ Fair and the VIII National Week of Science and Technology, both in Rio <strong>de</strong> Janeiro city.<br />

For the exhibitions, information and educational materials about the Antarctic ecosystems were <strong>de</strong>veloped: interactive theater, an<br />

activity using cut and painted Styrofoam hats shaped like animals (krill, fish, seal, seabird, penguin and whale); two informative<br />

panels about Antarctica and the research un<strong>de</strong>rtaken; a mo<strong>de</strong>l of Brazilian Antarctic Station Coman<strong>da</strong>nte Ferraz; collections of<br />

animals and plants of the continent; the game A Tour of the Antarctica, where participants are the pieces themselves; an interactive<br />

media which focuses on the continent, the story of its occupation and environmental problems generated by human occupation is<br />

presented by a whale and her calf born in Brazil, a seal and a penguin. An Agen<strong>da</strong> and t-shirts complete the work.<br />

Introduction<br />

Research centers and universities, which usually concentrate<br />

a large amount of researchers, are often isolated spheres<br />

of knowledge in society. Dissemination of science can be<br />

un<strong>de</strong>rstood as an action of social commitment, by citizens<br />

who have the opportunity and the privilege of participating<br />

in university institutions of higher education. As a rule,<br />

the scientific language of articles is very peculiar and its<br />

un<strong>de</strong>rstanding is carried out by peers and/or those interested<br />

in that specific area of knowledge, a restricted set of people.<br />

It is know that science should be one of the conditions<br />

necessary for the formation and training of individuals to<br />

<strong>de</strong>al with the world in which they are inserted.<br />

To transpose this language, the choice was for the<br />

<strong>de</strong>velopment of educational and playful materials, which<br />

have been successfully used in the teaching/learning<br />

process in various areas of knowledge such as Biology,<br />

Mathematics and Chemistry (Melim et al., 2009; Rossetto,<br />

2010; Alves, 2001; Barbosa et al., 2004; Zanom et al., 2008;<br />

Domingos & Recena, 2010). Analyzing di<strong>da</strong>ctic games,<br />

Gomes & Friedrich (2001) recognize the pe<strong>da</strong>gogical value<br />

of the di<strong>da</strong>ctic game, as well as an effective contribution to<br />

the teaching-learning process in the areas of Science and<br />

Biology.<br />

In this project, the purpose has been, the dissemination<br />

and popularization of science integrated actions aimed at<br />

getting to know the Antarctic region with its peculiarities,<br />

what the INCT-APA researchers do and to contribute<br />

to this knowledge to enable it to reach basic education<br />

and the general public. The project has been <strong>de</strong>veloped<br />

by Un<strong>de</strong>rgraduate Degree Course stu<strong>de</strong>nts in Biological<br />

Sciences and Fine Arts. It integrates a set of educational<br />

materials, activities and actions for planning, <strong>de</strong>veloping<br />

and implementing exhibitions for scientific exhibitions to<br />

the general public.<br />

Materials and Methods<br />

The methodology consists of transcribing the language<br />

of scientific articles <strong>de</strong>veloped by INCT-APA researchers<br />

in different areas of knowledge for the <strong>de</strong>velopment<br />

of educational materials. Teaching materials about the<br />

194 | Annual Activity Report 2011


Antarctic ecosystems are <strong>de</strong>veloped, emphasizing the<br />

importance of these environments to existing conditions<br />

in South America, in particular Brazil’s coastline and these<br />

and other materials are used on large exhibitions for schools<br />

and for the general public.<br />

The production of materials for scientific dissemination<br />

related to the knowledge of the coastal ecosystems of the<br />

State of Rio <strong>de</strong> Janeiro has formed the basis of materials<br />

<strong>de</strong>veloped about Antarctica since 2010 (Bozelli & Ferreira,<br />

2009, 2010)<br />

Experiences in ecology contributions to the teaching<br />

practice (Bozelli et al., 2011) offers a compilation of<br />

educational practices, games and dynamics of eleven out of<br />

the twenty-seven courses for teachers <strong>de</strong>veloped and carried<br />

out by the team. Playful activities as a facilitator of the<br />

teaching/learning process must be highlighted. The area of<br />

education in particular should take on renewed assignments,<br />

<strong>de</strong>veloping projects of educational experimentation,<br />

elaboration of teaching materials and implementation of<br />

new pe<strong>da</strong>gogical methods.<br />

The transcription of language takes different forms,<br />

namely: games, booklets, fact sheets, material for theater<br />

and exhibitions, using these and other materials, such as<br />

fixed specimens of Antarctic plants and animals.<br />

Informative and educational materials<br />

<strong>de</strong>veloped:<br />

1. Game “A Tour of the Antarctica”: The game consists of<br />

a path divi<strong>de</strong>d into gaps of different alternating colors<br />

(yellow, green, pink and blue) and for each color there<br />

are their respective cards. These cards, in addition to<br />

<strong>de</strong>termining the course of the game, contain information<br />

and fun facts about interactions among marine<br />

organisms, about birds and mammals, about the icy<br />

continent, as well as aspects of man’s relationship with the<br />

Antarctic environment. Players are the pins themselves<br />

and the number of spaces to move is <strong>de</strong>termined by<br />

rolling a giant dice, which contains numbers from 1 to 6.<br />

The objective of the game is to get children, adolescents<br />

and young people to know a little of the ecosystems of<br />

this region in an enjoyable and dynamic way (Figure 3).<br />

2. Interactive panel magnetized: an interactive panel<br />

illustrating the antarctic environments with the different<br />

Magnets shaped like animals and plants for the children<br />

to place, choosing the most appropriate place for each<br />

species and discussing with the mediator (Figure 4).<br />

3. DVD: Antarctica is first shown in a short animated<br />

vi<strong>de</strong>o by these characters: the blue whale, the blue whale<br />

cub, Wed<strong>de</strong>ll the seal and Gentoo the Penguin. In this<br />

animation the blue whale takes its calf, which was born<br />

near the Brazilian coast, to discover Antarctica for the<br />

first time. It uses the long journey to tell a little about the<br />

Antarctic continent and, when they arrive there, with<br />

the help of the seal and the penguin, news things will<br />

happen. After this brief introduction, the public is invited<br />

to interact with various topics present in the DVD,<br />

including a history of discovery and exploration, fauna,<br />

flora and the Coman<strong>da</strong>nte Ferraz Antarctic Station,<br />

where the researchers stay. The Antarctic ecosystems,<br />

their biodiversity, importance to global climate dynamics<br />

and some of the environmental problems created by<br />

human presence are presented. In this DVD there is<br />

also an interactive game of questions and answers for<br />

checking learning. Links to interesting websites on the<br />

topic will also be ma<strong>de</strong> available (Figure 5).<br />

6. T-shirts: for each exhibition, t-shirts i<strong>de</strong>ntifying the<br />

INCT-APA team were created (Figure 8).<br />

7. Fol<strong>de</strong>r: an educational fol<strong>de</strong>r is currently being<br />

<strong>de</strong>veloped, where there will be illustrations, stories and<br />

activities about the Antarctic ecosystems and some of<br />

their species, especially chosen since they generate great<br />

interest in the school public. The activities are games such<br />

as word search, crossword puzzles and cryptograms in<br />

which rea<strong>de</strong>rs can apply in a playful way the knowledge<br />

the acquired throughout the booklet.<br />
