ACKNOWLEDGEMENTS<br />
We thank the many contribu<strong>to</strong>rs <strong>to</strong> <strong>Galapagos</strong> marine science (particularly Dr Graham Edgar and Dr<br />
Jon Witman) and CI‐MMAS (Dr Les Kaufman, Scott Henderson, John Tschirky, Leah Bunce Karrer) for<br />
their technical oversight, outreach initiatives, financial support, and personal investment in the often<br />
seemingly tenuous sustainable future of the <strong>Galapagos</strong> Islands. It is very encouraging <strong>to</strong> see how<br />
large scale global initiatives such as MMAS can draw out not just diverse lessons for better ocean<br />
management but can also support important on‐site conservation at regional scales. Including<br />
<strong>Galapagos</strong> in the wider analysis is greatly appreciated. Considering extinction risk of not just species,<br />
but also the associated risk <strong>to</strong> economy and emerging island culture bodes well for realistic solutions,<br />
better informed stakeholders and decision makers locally, and wider global advocacy for protection<br />
of the world’s last unique marine refuge areas.<br />
THE CHARLES DARWIN FOUNDATION<br />
The Charles Darwin Foundation (CDF), which in 2009 celebrated the 50th anniversary of its founding,<br />
is an international non‐profit organization with its operational base in the <strong>Galapagos</strong> Islands, 1,000<br />
kilometers from the coast of Ecuador. CDF's mission is "<strong>to</strong> provide knowledge and assistance through<br />
scientific research and complementary action <strong>to</strong> ensure the conservation of the environment and<br />
biodiversity in the <strong>Galapagos</strong> Archipelago". <strong>Galapagos</strong> faces numerous challenges: increasing levels<br />
of <strong>to</strong>urism; the continuous threat of introduced species which endanger its unique biodiversity;<br />
climatic change; and a growing human population which requires food, services, and other amenities.<br />
The CDF, through its unique agreement with the Government of Ecuador <strong>to</strong> provide technical advice<br />
<strong>to</strong> <strong>Galapagos</strong> stakeholders and especially <strong>to</strong> the <strong>Galapagos</strong> National Park Service (GNPS), is at the<br />
forefront of science for the protection and conservation of both terrestrial and marine ecosystems,<br />
and its staff (the majority of whom are <strong>Galapagos</strong> natives) <strong>to</strong>gether with many international,<br />
Ecuadorian and <strong>Galapagos</strong> volunteers, work tirelessly <strong>to</strong> bring the highest standard of research and<br />
technical assistance <strong>to</strong> <strong>Galapagos</strong> decision makers. Research specialties such as res<strong>to</strong>ration,<br />
ecosystem and species moni<strong>to</strong>ring, and social sciences are supported by the largest collections<br />
worldwide of <strong>Galapagos</strong> baseline data and library resources and teams of environmental education<br />
specialists, community outreach, and technical advisors. The CDF also maintains close links <strong>to</strong> an<br />
international network of scientists, technical experts, and "Friends of <strong>Galapagos</strong>", and disseminates<br />
information widely <strong>to</strong> ensure that one of the last remaining natural treasures of the world remains in<br />
the public consciousness at home and abroad. By maintaining excellent standards of research and<br />
technical assistance that are directly relevant <strong>to</strong> the changing needs of <strong>Galapagos</strong>, and by continuing<br />
<strong>to</strong> strive for ecological, environmental, and economic stability in the <strong>Galapagos</strong> Islands and <strong>Galapagos</strong><br />
Marine Reserve (GMR). CDF plays a key role in creating a sustainable <strong>Galapagos</strong>.<br />

MARINE MANAGEMENT AREA SCIENCE<br />
INSIGHTS FROM GALAPAGOS<br />
FINAL REPORT FROM THE CHARLES DARWIN FOUNDATION:<br />
EXECUTIVE SUMMARY<br />
January 28, 2010<br />
GOALS:<br />
1. Development of a long term <strong>Galapagos</strong> Marine Reserve (GMR) coastal/ocean moni<strong>to</strong>ring program<br />
designed for the <strong>Galapagos</strong> National Park Service (GNPS) and local partners, linked <strong>to</strong> global and<br />
regional needs and initiatives.<br />
2. Innovative Marine Management Area <strong>Science</strong> in the context of globally unique marine environment<br />
at risk under considerable climatic variability, a relatively data rich multi-user ecosystem, and the<br />
largest Marine Protected Area (MPA) refuge in the Eastern Tropical Pacific (ETP) region from<br />
industrial fishers.<br />
3. Advocate positive change through transparent flow of information <strong>to</strong> users and dissemination of<br />
appropriate recommendations that encourage informed stakeholder decisions.<br />
RESULTS:<br />
Through analysis of <strong>Galapagos</strong> and wider ETP regional data coupled with climate risk assessment,<br />
scientists inferred the following:<br />
• There is a direct positive correlation between biomass of preda<strong>to</strong>ry fish and degree of<br />
enforcement in MPAs.<br />
• Fishing impacts on preda<strong>to</strong>ry fish and concomitant density of macro algae habitats show an<br />
inverse relationship <strong>to</strong> distance from port zones.<br />
• Certain species that consistently associate with fished or non-fished “sanctuary” zones or are<br />
conspicuously absent have potential as indica<strong>to</strong>rs for MMA effectiveness.<br />
• Past El Niño Southern Oscillation (ENSO) observations suggest there is a high risk of<br />
extinction among species unless the exacerbating human footprint is reduced.<br />
• During periods of climate stress, a range of connected, distinct yet shifting oceanographic<br />
regimes provides an opportunity for niche habitats <strong>to</strong> expand and contract.<br />
• Increasing the area of protected coastal zones in sensitive areas by as little as 2% would<br />
afford significant protection <strong>to</strong> certain threatened species and marine habitats.<br />
• Protection aids s<strong>to</strong>ck recovery, evidenced by higher density of preda<strong>to</strong>ry reef fish of<br />
reproductive size in protected areas.<br />
• Fragmented <strong>Galapagos</strong> corals are likely <strong>to</strong> be severely impacted by increased acidification<br />
stress and should be considered a particularly sensitive <strong>Galapagos</strong> habitat.<br />
• Res<strong>to</strong>ring <strong>to</strong>p-down controls of habitat engineers and bioeroders such as urchins will more<br />
than likely improve reef resilience in the face of strong climate impacts.<br />
4
• Corals that survived the El Niño event in 1982/3 seem <strong>to</strong> have been resistant <strong>to</strong> the stress of<br />
the following strong event in 1997/8 and are now undergoing signs of recovery near those few<br />
remaining reefs. There appears <strong>to</strong> have been a strong selection for heat resilient species/<br />
zooxanthellae combinations in recent his<strong>to</strong>ry.<br />
• Nature based <strong>to</strong>urism selects for high priority conservation sites, but introduces bias in<br />
estimations of diversity compared <strong>to</strong> sites with fewer visitations. Obviously more visitation<br />
improves the chance that rare or uncommon species are observed.<br />
• Until recently the significant loss of important habitat forming <strong>Galapagos</strong> species went<br />
unheralded.<br />
• The extremes of moderate-strong ENSO events and subsequent recovery intervals generate a<br />
constant flux in the composition of benthic environments between rapid colonizers and<br />
established slow growing benthos such as hermatypic corals.<br />
• <strong>Galapagos</strong> is a globally unique field labora<strong>to</strong>ry for assessing species and community level<br />
responses and effects of management measures under extreme oceanographic events such<br />
as ENSO and global warming.<br />
• <strong>Galapagos</strong> still requires an information management system based on ecosystem moni<strong>to</strong>ring<br />
which ensures continuity of shared information.<br />
• The rate of change as well as the magnitude of climatic events affects coral health. Cold<br />
water shock can be as much a stress as increased temperatures.<br />
• Relative abundances of bioeroders (e.g. sea urchins) and grazers indicate regime shifts in<br />
habitat forming reef. This may be useful in assessing regressions <strong>to</strong> lower biodiversity states.<br />
• <strong>Galapagos</strong> corals are likely <strong>to</strong> be among the first affected by ocean acidification. The natural<br />
marine environment in <strong>Galapagos</strong> has particularly high CO 2 levels, which impacts stabilizing<br />
reef cementation reducing resistance <strong>to</strong> erosion and potentially affecting growth rates.<br />
• Coastal fisheries can have particularly high impact on climate sensitive species, suggesting<br />
that a fisheries policy shift <strong>to</strong>ward species that may benefit from climate shifts would improve<br />
reduce extinction risk before climate impacts.<br />
• Well managed <strong>to</strong>urism zones promote protection of high diversity sites by assigning an<br />
economic value greater and distinct from profits derived from extraction activities with higher<br />
ecological impact.<br />
• New alternatives for traditional <strong>Galapagos</strong> sec<strong>to</strong>rs such as pesca vivencial (<strong>to</strong>urists<br />
accompanying fishers) or proposals for pseudo-long-lining in deep water need <strong>to</strong> be carefully<br />
scrutinized and clarified <strong>to</strong> ensure that appropriate moni<strong>to</strong>ring and governance can take place.<br />
SUMMARY AND CONCLUSIONS:<br />
The inclusion of <strong>Galapagos</strong> in the wider MMAS project promotes marine research in the archipelago,<br />
both for the benefit of <strong>Galapagos</strong> and for marine science and climate studies generally. A number of<br />
interesting results point <strong>to</strong> the importance of further studies <strong>to</strong> develop this contribution further during<br />
2010-2012. Since the area already has considerable interdisciplinary data and contains so many<br />
diverse inter-related habitats a relatively low investment in research in <strong>Galapagos</strong> marine<br />
environments within a larger interconnected MMA regional and global context, can reap dividends in<br />
terms of knowledge and advocacy needed <strong>to</strong> ensure optimum conservation of marine ecosystems in<br />
the face of global climate change.<br />

I. AN OVERVIEW OF MMAS‐GALAPAGOS PROJECT GOALS<br />
The <strong>Galapagos</strong> Marine Management Area <strong>Science</strong> (MMAS) grant from May 2008 – April 2010<br />
supported the fieldwork component of a long term <strong>Galapagos</strong> Marine Reserve (GMR) moni<strong>to</strong>ring<br />
program examining variability of subtidal community composition under differing management and<br />
oceanographic regimes. It also encouraged publication of data and development of <strong>Science</strong> <strong>to</strong> <strong>Action</strong><br />
(S2A) messages from a body of comparative research between <strong>Galapagos</strong> and other connected sites<br />
in the Eastern Tropical Pacific (ETP). Towards the end of the project (and presumably in<strong>to</strong> its future<br />
incarnation) it facilitated standardization of data and research questions across themes central <strong>to</strong><br />
improved MPA management globally – i.e. are MPAs effective in meeting stakeholder criteria for<br />
ecosystem services, how do MMAs respond <strong>to</strong> climate perturbations under a suite of human<br />
stressors? In a world where acidification stress, shifts in ocean‐atmosphere systems and background<br />
heating seems inevitable, how can we encourage ecosystem resilience <strong>to</strong> disturbance and reduce<br />
extinction risk etc.? It sets the scene for a common MMA research agenda.<br />
By increasing the value of otherwise unconnected regional studies as part of broader MMAS cross<br />
node comparisons between other global Marine Managed Areas (MMAs) we hope <strong>to</strong> distill from the<br />
data key conservation messages targeted <strong>to</strong> S2A advocacy and solutions for managers that can be<br />
realistically implemented. Those insights gained during the two year project are summarized here<br />
from recent workgroup publications.<br />
The <strong>Galapagos</strong> node component was originally a subset of the wider MMAS/ CI‐ETPS MPA network.<br />
Specifically the deliverables included:<br />
(1) Standardization of ETP reef survey pro<strong>to</strong>cols where appropriate with consideration of the<br />
fundamental similarities and differences between subtidal reef communities in <strong>Galapagos</strong> and<br />
across the other ETP regions (Coiba, Panama; Malpelo & Gorgona, Colombia; Isla Coco, Costa<br />
Rica; Machalilla, mainland Ecuador).<br />
(2) Close cooperation between marine scientists working between different regions <strong>to</strong>wards<br />
common methodologies and MMAS research goals with CDF moni<strong>to</strong>ring support extended <strong>to</strong><br />
emerging MPAs in the ETP.<br />
(3) Generation of a comparable two year dataset across the ETP region for <strong>Galapagos</strong> between<br />
different fisheries extraction and sanctuary zones (protected and <strong>to</strong>urism) that with a wider<br />
analysis of his<strong>to</strong>rical pre/post 1982‐83 ENSO observations led <strong>to</strong> a series of peer review<br />
articles and key S2A messages.<br />
MMAS objectives mirror the concept of CDF marine research which is strongly orientated <strong>to</strong>wards<br />
recommendations for applied improved GMR management practice based upon robust science<br />
support. CDF marine research continues <strong>to</strong> work within those expectations, obligations and<br />
management goals as part of a 10 year stakeholder process dating back <strong>to</strong> before the declaration of<br />
the <strong>Galapagos</strong> Marine Reserve. Those goals include:<br />
(1) Development of a long term GMR coastal / ocean moni<strong>to</strong>ring program designed for GNPS and<br />
local partners, linked <strong>to</strong> global and regional needs and initiatives.<br />
(2) Innovative Marine Management Area <strong>Science</strong> in the context of (a) a globally unique marine<br />
environment at risk under considerable climatic variability, (b) a relatively data rich multi‐user<br />
ecosystem and (c) the largest MPA refuge in the ETPS region from industrial fishers.<br />
6
(3) Advocate positive change through (a) transparent flow of information <strong>to</strong> users and (b)<br />
dissemination of appropriate recommendations that encourage informed stakeholder<br />
decisions.<br />
II. STATUS OF RESEARCH<br />
STANDARDIZATION OF MARINE MONITORING ACROSS THE ETP REGION.<br />
The <strong>Galapagos</strong> subtidal survey data (2007‐2008) collected under the project formed part of a<br />
wider regional ETP MMA study (Edgar et al. 2009). It also currently is part of a global database<br />
being applied if and where relevant <strong>to</strong> the wider cross‐node MMAS analysis between Belize, Fiji,<br />
and Brazil.<br />
Charles Darwin Research Station (CDRS) subtidal survey methods formed the basis of a two year<br />
process with lead PIs from the Coiba, Malpelo, Machallila, Coco and Gorgona regions <strong>to</strong> generate<br />
a first integrated and comparative study of MMA effects across the ETP. A common survey<br />
pro<strong>to</strong>col was agreed upon which paved the way for future comparisons (see Annex 1).<br />
The subtidal moni<strong>to</strong>ring methodology for <strong>Galapagos</strong> was originally developed in 2000 on the<br />
cusp of the formation of the GMR as we know it <strong>to</strong>day ‐ in part <strong>to</strong> provide biodiversity estimates<br />
<strong>to</strong> endorse its UNESCO world heritage status but perhaps more importantly <strong>to</strong> data‐mine the link<br />
between a comprehensive measure of ecosystem state and management. It confronts<br />
considerable small scale variability under larger ENSO climate signals, and considers<br />
biogeography patterning for representative protection of sensitive areas. It was created <strong>to</strong><br />
standardize benchmarks for before‐after comparisons given the implementation of new<br />
management <strong>to</strong>ols such as coastal take and no‐take zonation within what was at that time a new<br />
(and ambitious) participa<strong>to</strong>ry and adaptive management paradigm.<br />
Methods originally proposed by Bustamante and Edgar (Linea Base de Biodiversidad; Danulat &<br />
Edgar Eds. 2001) built upon earlier surveys from 1994‐1999 comprising early taxonomic<br />
inven<strong>to</strong>ries for subtidal fish, sessile macroinvertebrate and algae and mobile macroinverterbrate<br />
groups. In subsequent years improved field pro<strong>to</strong>cols, taxonomic resolution (particularly for<br />
sessile species), regulated data entry with better quality control as well as consistency between<br />
research divers has generated a fairly unique 10 year dataset for MPA evaluation. A detailed<br />
description of the moni<strong>to</strong>ring and site selection through the 2004 JMP process is given in CDF<br />
technical report Banks et al. (2006).<br />
Distinctions between <strong>Galapagos</strong> moni<strong>to</strong>ring over this period and the common shared moni<strong>to</strong>ring<br />
approach in other regions were mostly in the form of complementary data collections:<br />
1. Pilot moni<strong>to</strong>ring groups at the community level:<br />
7
a. A 30 minute census of pelagic species in near shore blue water analogous <strong>to</strong> that<br />
applied in Malpelo, Colombia (GPS tracking added <strong>to</strong> standardize drift)<br />
complemented in part the ongoing CDF shark census work with other ETP<br />
partners.<br />
b. Mesogastropods were added <strong>to</strong> the other three principle moni<strong>to</strong>ring groups<br />
(collected in 10 x 0.25m 2 sessile quadrats at each 15m/6m depth strata) <strong>to</strong><br />
explore possible indirect trophic effects.<br />
c. Deep (40‐100m) Remotely Operated Vehicle deployments opportunistically<br />
surveyed below safe diving limits. Once widespread species thought locally<br />
extinct since 1984 such as the oc<strong>to</strong>coral sea pens Vigularia galapagensis,<br />
Cavernulina c.f. darwini, and Ptilosarcus undulatus were rediscovered with deep<br />
water distributions in the central archipelago. Surveys of deep anoxic benthos<br />
and bacterial mats in the Darwin Bay crater, Isla Genovesa also suggests<br />
circulation problems in this intensively used <strong>to</strong>urism anchorage.<br />
2. Developing comparative methods:<br />
a. A comparative review of sessile moni<strong>to</strong>ring methods between the point<br />
intersection quadrat technique traditionally used over heterogeneous <strong>Galapagos</strong><br />
rocky reef and those larger area quadrats employed by researchers working over<br />
contiguous coral benthos in Isla Coco, Malpelo and Coiba.<br />
The appraisal suggests that these methods be complementary and not necessarily<br />
exclusive. It was important <strong>to</strong> differentiate separate goals between the two<br />
methodologies. Point intersection methods considered (1) rapid assessment of<br />
sessile benthos (at relatively high taxonomic resolution over small yet dispersed<br />
areas with replication i.e. – 1620 sampled points over 20 replicate quadrats and 2<br />
depth strata but not an area measure) as distinct from (2) a reduced number of<br />
long term fixed area plots in areas with high coral coverage (sampling with x 12<br />
greater spatial coverage, typically 600 sample units, lower taxonomic resolution<br />
and ~x 3‐6 immersion time <strong>to</strong> complete).<br />
The diverse benthic assemblages across <strong>Galapagos</strong> rocky reef and the<br />
considerable logistic challenges for representative moni<strong>to</strong>ring over 3‐5<br />
biogeographic regions and ~1750 Km coastline favors point intersection quadrat<br />
methods for rocky reef systems by well trained science divers in the <strong>Galapagos</strong><br />
region. However recognizing the value of improved coverage in contiguous coral<br />
reef for comparisons with Isla Coco, Malpelo, Gorgona and Coiba we began <strong>to</strong><br />
also implement replicated fixed 1 x 10m 2 quadrant blocks in a subset of northerly<br />
coral sites with >50% coral cover following their established methodology.<br />
8
. Pho<strong>to</strong>quadrat methods were applied in certain long term moni<strong>to</strong>ring sites.<br />
<strong>Galapagos</strong> has considerable taxonomic experience with sessile epifauna and algae<br />
which has helped in post processing of imagery for a long term objective data<br />
bank. The value of such pho<strong>to</strong>quadrats lies in an objective long term record and<br />
for comparisons between other regions or instances where taxonomic expertise<br />
during the dive is unavailable. This was particularly useful for example in<br />
quantifying broad scale habitat shifts from pho<strong>to</strong>graphy taken coincidentally<br />
before and after the strong 1982/3 ENSO event (Edgar et al. 2009).<br />
3. Sampling for environmental correlates:<br />
a. Oceanographic data was collected at all localities through CTD‐Fl profiling and<br />
335um/20um zooplank<strong>to</strong>n and phy<strong>to</strong>plank<strong>to</strong>n net <strong>to</strong>ws. This complements a<br />
larger 3 year seasonal dataset collected during the <strong>Galapagos</strong> NASA‐Ocean<br />
project (2004‐2007) comprising >60 coastal and open water fixed sampling points<br />
during 11 day archipelago wide ocean expeditions. In practice these “snapshots”<br />
capture the regime during the sampling day, and are placed in the context of time<br />
series oceanographic data from in‐situ subtidal temperature loggers and satellite<br />
derived measures (SeaWiFS, MODIS‐AQUA, AVHRR).<br />
b. Two long term subtidal temperature logger stations at 10m and 20m depth were<br />
renovated for continuous data collection in the far north (Wolf) and Western<br />
upwelling zone (Fernandina) with 3 CTDs (Conductivity Temperature Depth<br />
sensors) being prepared for long term deployments with <strong>Galapagos</strong> National Park<br />
Service (GNPS) and Institu<strong>to</strong> Nacional Oceaonografico de la Armada (INOCAR)<br />
partners in<strong>to</strong> 2010.<br />
4. Collaborative sampling:<br />
a. Dr Jon Witman, Brown University continues his decadal study of trophic<br />
interactions across subtidal vertical walls in upwelling and non‐upwelling sites –<br />
we are contributing within the CDF dataset <strong>to</strong> a PhD study of functional group<br />
resilience and complexity in the first half of 2010.<br />
b. As counterpart <strong>to</strong> the MMAS project we also ran a three year Darwin Initiative<br />
coral mapping exercise linked with IUCN red listing work for those groups with a<br />
range of invited regional and taxonomic experts. This greatly strengthened the<br />
formation of the ETP technical marine group.<br />
c. CDRS divers transferred subtidal methods for rocky reef evaluation participating<br />
directly in surveys in Los Roques (Venezuela), Isla Coco (Costa Rica), Machalilla<br />
(Ecuador) and with CDF trained divers in Coiba (Panama).<br />
5. Inclusion of additional survey sites:<br />
9
a. In addition <strong>to</strong> the 65 core sampling sites, surveys included a base line for an<br />
Environmental Impact Assessment of the Bar<strong>to</strong>lome anchorage (Isla Santiago)<br />
prior <strong>to</strong> GNPS/INOCAR installation of low impact moorings with a follow up<br />
survey in 2009. This included collections of soft sediment in‐fauna, a marine trash<br />
survey, video transects and subtidal reef taxa. This was part of a multi‐institution<br />
no anchor initiative <strong>to</strong> reduce physical damage <strong>to</strong> fragile benthos.<br />
b. Distinct dominant macroalgae communities in western Fernandina Island were<br />
surveyed (4 sites) with emphasis upon algae collections for improved<br />
identification, including a directed search for endemic deep kelp (IUCN VU)<br />
Eisenia galapagensis. A survey was also attempted on the western shore of<br />
Fernandina <strong>to</strong> examine recruitment upon newly formed subtidal lava after a<br />
recent volcanic eruption reached the shore.<br />
c. We discovered regions <strong>to</strong> the west of Isla Darwin with considerable continuous<br />
coral cover harboring some of the largest colonies remaining <strong>to</strong> date (radial<br />
diameter ~ 7m for Porites lobata), and began <strong>to</strong> follow the largest recovering reef<br />
framework originally moni<strong>to</strong>red by Glynn in the 1970’s. Two new coral reference<br />
sites in the central archipelago were also surveyed in Española and Floreana using<br />
the point transect methods applied in the far northerly reefs.<br />
d. We also under<strong>to</strong>ok surveys of two longer time series sites in Floreana Island<br />
(originally Pew fellowship project sites from 2000‐2003 sampled every 3 months).<br />
III. DATA APPLICATION.<br />
The two year CDF subtidal moni<strong>to</strong>ring dataset was applied in (1) an ETP level analysis with regional<br />
co‐authors (Edgar et al. MMA effectiveness, submitted; Cortez et al. ETP biogeography, in<br />
development; Wolff et al. ETP trophic modeling, in development), (2) <strong>Galapagos</strong> specific publications<br />
(Edgar et al. 2008 generates <strong>Galapagos</strong> Key Biodiversity Area (KBA) Criteria, and Edgar et al. 2009<br />
examines extinction risk via climate – fisheries interactions) and (3) recently submitted as part of the<br />
MMAS global cross node analysis (in development) and included in a global analysis of reef fish<br />
resilience as a mediation function of biodiversity and functional redundancy before human<br />
disturbance (Mora et al. in review 2010).<br />
IV. SCIENCE TO ACTION: INSIGHTS FROM GALAPAGOS REGARDING MMA<br />
EFFECTIVENESS UNDER DIFFERENT POLICY AND STRATEGIES.<br />
The <strong>Science</strong> <strong>to</strong> <strong>Action</strong> messages are based around published work or analysis submitted <strong>to</strong> peer<br />
review journals, from field observations and ongoing CDF work under GMR research and the wider<br />
CDF climate change initiative. Where the ETP dataset is mentioned we refer <strong>to</strong> the combined analysis<br />
of data from <strong>Galapagos</strong>, Machalilla, Coiba, Isla Coco, Malpelo and Gorgona from 2007‐2008:<br />
10
1. ECOLOGICAL MONITORING AND MANAGEMENT EFFECTIVENESS<br />
More preda<strong>to</strong>ry fish in well enforced MPAs vs. poorly enforced MPAs.<br />
Comparisons between ETP MMAs <strong>Galapagos</strong> and Machalilla (Ecuador), Isla del Coco (Costa Rica),<br />
Coiba (Panama), and Isla Malpelo and Isla Gorgona (Colombia) showed considerable ecological<br />
differences associated with different levels of MPA enforcement and local fishing pressure. Well<br />
protected MPAs harbored subtidal communities with around 5x greater biomass of carangid jacks,<br />
sharks and groupers when compared <strong>to</strong> poorly enforced MPAs. Poorly enforced MPAs had<br />
approximately x2 biomass of large carnivorous fish compared <strong>to</strong> openly fished areas (Edgar et al.<br />
2008). Highly fished sites also showed significant densities of seastars and Eucidaris Sp. urchin grazers<br />
and higher densities of the sabre<strong>to</strong>oth blenny Plagiotremus azaleas and triple fin blenny Lepidonectes<br />
corallicola. Conversely >20% of seastars in MPA sites showed evidence of fish predation suggesting<br />
their use as indica<strong>to</strong>rs of indirect secondary fisheries impacts.<br />
Poorly protected ETP MPAs showed an 80% decline in fish biomass similar <strong>to</strong> fished sites. In zones<br />
where the capacity for management is limited (even if a legal framework is in place) greater<br />
conservation return may result from a smaller subset of better protected sites until wider more<br />
effective vigilance measures can be applied. In the absence of sound governance, net conservation<br />
gain may be reached by compromise. Poorly enforced MPAs for example may also represent<br />
concession zones for negotiation with fisheries stakeholders for experimental fisheries rotation etc.<br />
or interchanged for protection of under‐represented high biodiversity or sensitive species areas.<br />
Direct effects of fishing in the ETP did not seem <strong>to</strong> extend <strong>to</strong> herbivorous fish as observed on heavily<br />
exploited Indo‐Pacific and Caribbean reefs.<br />
Fishing impacts preda<strong>to</strong>ry fish reducing macro algae habitat<br />
Distance from fishing ports shows an inverse correlation with ecological metrics of classic fishing<br />
effects, with densities of preda<strong>to</strong>ry reef fish decreasing significantly and macroalgaes increasing away<br />
from port zones. Although the emerging trends seem intuitive, next steps in analysis require a better<br />
appraisal of the fishing dynamic <strong>to</strong> substantiate the assumption that distance from port and fishing<br />
pressure are strongly correlated.<br />
Certain species associate with fished and non‐fished areas<br />
Across the ETP 2007‐2008 dataset a multivariate analysis of fishing impact and community<br />
composition (based upon 24 indica<strong>to</strong>r metrics of primary, secondary and higher order trophic effects<br />
of fishing) positively associated fishing with the presence of globefish Diodon holocanthus, and the<br />
seastar Phataria unifascialis and negatively associated the bicolor parrotfish Scarus rubroviolaceus,<br />
the rainbow wrasse Thalassoma lucasanum and the urchin Diadema mexicanum.<br />
Not surprisingly fish that were negatively correlated with fishing impact were the larger reef and<br />
close pelagic preda<strong>to</strong>rs such as the Jack Caranx melampygus, grouper Derma<strong>to</strong>lepsis derma<strong>to</strong>lepsis<br />
and snapper Lutjanus novemfasciatus, and those positively associated with fishing those cryptic<br />
species with smaller body sizes such as P.azaleas, L. corallicola and bravo clinid Labrisomus<br />
11
dentriticus. Diadema and Tripnuestes urchins were negatively correlated <strong>to</strong> fished areas whilst<br />
Eucidaris was ubiqui<strong>to</strong>us in fished zones.<br />
Past ENSO observations suggest extinction risk is high unless “exacerbating” human<br />
footprint is reduced.<br />
Based upon his<strong>to</strong>rical and current observations that imply probable post‐El Niño extinctions (Edgar et<br />
al. 2009) the prospect of future biodiversity loss of threatened marine species seems likely unless<br />
“climate conscious” adaptation measures are employed <strong>to</strong> reduce compounding risk presented by<br />
human activity in the coastal zone. Since low impact scenarios based on past ENSO patterns have<br />
already been implicated in significant marine habitat restructuring and extinction risk, ecosystem<br />
diagnostics for benthic resilience should be employed <strong>to</strong> moni<strong>to</strong>r and better respond <strong>to</strong> future<br />
climate shifts, coupled with directed management measures designed <strong>to</strong> ameliorate the <strong>Galapagos</strong><br />
human footprint.<br />
2. HABITAT CONNECTIVITY (INCLUDING CROSS SHELF AND INTERREEFAL STUDIES)<br />
A range of connected distinct yet shifting oceanographic regimes provides opportunity for<br />
spatial expansion and contraction of suitable niche habitat during periods of climate<br />
stress across the GMR.<br />
The biodiversity patterning (CDF Base line 2002, Edgar et al 2004) across <strong>Galapagos</strong> temperate,<br />
upwelling and panamic/indo‐pacific species affinities under ENSO and seasonal shifts lends itself <strong>to</strong><br />
connected shifting refuge areas and "fringe" settlement zones (if climate shifts gradually and not<br />
abruptly). An example includes evidence of thousand year fossil records of uplifted massive corals in<br />
a shallow heated (Urvina) bay surrounded by otherwise inhospitable cold upwelled water on the<br />
western coast of Isabela.<br />
During the ETP regional analysis the magnitude of variation in subtidal marine communities across<br />
the <strong>Galapagos</strong> region (~3°) was found <strong>to</strong> be of the same order as that across the entire 10° latitudinal<br />
span of continental sites from Coiba (Panama) <strong>to</strong> Machalilla (Ecuador). Wolf Island in particular shows<br />
high sessile biotic similarity <strong>to</strong> sites in Coiba and Gorgona (Colombia) whilst Wolf, Darwin, Isla Coco<br />
(Costa Rica) and Malpelo (Colombia) show high affinity in fish assemblages from Panamic and Indo‐<br />
Pacific provinces.<br />
3. POPULATION CONNECTIVITY<br />
Priority updates <strong>to</strong> <strong>Galapagos</strong> coastal zoning of >2% will improve representative<br />
protection of threatened species and habitat.<br />
Current <strong>Galapagos</strong> MPAs ameliorate, but do not prevent ecosystem impacts during strong ENSO<br />
disturbances and can be improved. There is aperture for improved protected coverage of particularly<br />
sensitive areas particularly in the upwelling west and far northerly islands. Current protected area<br />
zoning covers 16% of the reserve (including 10% non‐extractive <strong>to</strong>urism areas) and ideally should be<br />
increased <strong>to</strong> ~25%. Particularly sensitive areas which deserve improved levels of protection include<br />
Wolf and Darwin, Caleta Iguana, Punta Essex and Wreck Bay. Nursery zones should be considered<br />
12
within existing fisheries areas <strong>to</strong> complement spill over from the smaller MPAs, as well as ordination<br />
of new low impact extraction modalities such as pesca vivencial (<strong>to</strong>urists accompanying fishers).<br />
Effective MPAs that encourage spill over are shown <strong>to</strong> be at least several Km in length across the<br />
literature. A cumulative extension of 26 Km has been suggested by Edgar et al. (2008) across all MPAs<br />
<strong>to</strong> improve their relative effectiveness incorporating aforementioned unprotected sites harboring<br />
unique threatened endemics and including protected subzones within multiple use port areas in the<br />
three main populated islands of San Cris<strong>to</strong>bal, Santa Cruz and Isabela under regular human influence.<br />
Reproductive sized preda<strong>to</strong>ry reef fish are more abundant in protected sanctuary zones.<br />
<strong>Galapagos</strong> preda<strong>to</strong>ry fish population size structure suggests that the current zoning has the potential<br />
<strong>to</strong> protect reproductive s<strong>to</strong>ck for those fished species – certainly coastal fin fish such as the insular<br />
endemic bacalao M.olfax which have large aggregations in the western upwelling zone of Canal<br />
Simon Bolivar. Further analysis is needed <strong>to</strong> determine whether MPAs are extensive enough <strong>to</strong><br />
encourage s<strong>to</strong>ck recovery of other exploited species given current management measures –<br />
particularly for benthic feeders such as lobsters and sea cucumber with depressed populations that<br />
are likely linked <strong>to</strong> recruitment pulses within ENSO cycles.<br />
High global extinction risk for corals suggest that viable source populations encouraging<br />
exogenous recruitment be protected at the regional level between ETP MMAs.<br />
Under global warming scenarios with stronger ENSOs, although connectivity between coastal coral<br />
communities <strong>to</strong> <strong>Galapagos</strong> may increase with increased flow from Panamic and Indo‐Pacific provinces<br />
it seems likely that many species would not survive the combination of background acidification<br />
stress and increased temperature maxima. Regional scale degradation of colonies in other MPAs in<br />
the ETP region through accumulated anchor damage or indirect fishing/ bio‐erosion effects would<br />
also reduce recruitment from potential source regions (eg. “continental Ecuador <strong>Galapagos</strong>” or<br />
“Coiba/Isla Coco <strong>Galapagos</strong>”) during ENSO recovery intervals.<br />
4. RESILIENCE<br />
Res<strong>to</strong>ring a <strong>to</strong>p‐down control of habitat engineers such as herbivorous urchins improves<br />
reef resilience before strong climate impacts.<br />
Despite the regularity of EN the <strong>Galapagos</strong> ecosystem is not well adapted <strong>to</strong> resist ecological impacts<br />
particularly where climate stress is compounded by recent human interactions.<br />
Overfishing reduces ecosystem resilience. Strong ENSOs have occurred periodically for thousands of<br />
years, and presumably the various native and endemic species suspected <strong>to</strong> be extinct since 1983 had<br />
survived those previous events. The greatest single perturbation <strong>to</strong> the marine environment after<br />
ENSO in the coastal zone over the past 40 years is represented by the largely unchecked growth in<br />
coastal fisheries for sea cucumber, 3 species of rock lobster, illegal shark fisheries and coastal fin fish<br />
such as bacalao Mycteroperca olfax, assorted Serranids, Lutjanids, and Carangnids. This hypothesis is<br />
also supported by trophic modeling results (Bustamante et al. 2008, Ruiz in prep.). In particular<br />
comparisons with the well protected MPA in Coco Island, Costa Rica, and the analogous oceanic<br />
13
pinnacles of fished Wolf and Darwin with reduced protection clearly show lower densities of Eucidaris<br />
urchins, and increased lobster densities.<br />
Given these observations it would seem advisable that Wolf and Darwin (harboring the last remaining<br />
reef frameworks) be excluded from lobster fishing if coral health is <strong>to</strong> be maintained after a future<br />
strong EN event. Top down control of bioeroders is likely key <strong>to</strong> preventing a semi‐permanent regime<br />
shift where corals (already under considerable climate and acidification stress) are lost. The same<br />
holds true for other parts of the reserve.<br />
5. RESISTANCE TO EXTINCTION<br />
El Niño, grazers and fisheries interact <strong>to</strong> greatly elevate extinction risk for <strong>Galapagos</strong><br />
Marine Species (Edgar et al. 2009).<br />
Forty‐five <strong>Galapagos</strong> marine species fulfill IUCN red listing threatened criteria – 5 mammals, 6 birds, 6<br />
fish, 1 echinoderm, 7 corals, 6 brown algae, 9 red algae. At least 2 species, the black spotted<br />
damselfish Azurina euplama and 24 rayed seastar Heliaster solaris are probably extinct. Since no<br />
marine fish has been registered by IUCN or otherwise as extinct this is particular noteworthy (Figure<br />
1).<br />
Highest densities of threatened marine species with restricted ranges are located in the western part<br />
of the Isabela and Fernandina Islands. Using modified Key Biodiversity Area (KBA) vulnerability and<br />
irreplacability criteria, an estimated 30% of threatened species fall within unprotected areas (where<br />
>1% of the population permanently or seasonally resides) which could be improved with a 2%<br />
minimum increase in protected coastal coverage. Seven IUCN red listed species extending in<strong>to</strong> the<br />
coastal fringe were useful in the KBA process due <strong>to</strong> their regular occurrence and discrete<br />
distributions – <strong>Galapagos</strong> penguins (Sphendiscus mendiculus), the flightless cormorant (P.harrisi),<br />
Whale Shark (Rhincodon typus), the <strong>Galapagos</strong> sealion (Zalophus wollebaeki) and the <strong>Galapagos</strong> fur<br />
seal (Arc<strong>to</strong>cephalus galapagensis), Mangrove finch C. heliobates and the lava gull Lavus fuliginosus.<br />
The presence of the first two marine birds also showed an indirect correlation with other cryptic<br />
endemics suggesting their use as possible umbrella species in prioritizing any shifts or improvements<br />
<strong>to</strong> protected zones.<br />
Repetitive ENSO stress throughout recent his<strong>to</strong>ry suggests selection for coral associations<br />
that better withstand gradual warming.<br />
Coral / zooxanthellate clade associations seem <strong>to</strong> have been whittled down <strong>to</strong> an EN resistant subset<br />
that persisted since the strong 1982/83 event. Those remaining were less affected by the subsequent<br />
1997/98 event (Glynn, 2009)). Since 2002 Glynn reports modest recovery around the few remaining<br />
reef structures in the far northern islands.<br />
14
Figure 1. Number of species on the <strong>Galapagos</strong> threatened marine species list recorded at islands in the three major<br />
biogeographic zones before (dark bars) and after (light bars) the 1982/83 El Niño. Threatened marine vertebrates and corals<br />
(Pocillopora elegans and P. inflatus) that are widely distributed across the archipelago have been excluded from <strong>to</strong>tals.<br />
Conservation and <strong>to</strong>urism zones with prohibition on fishing are shown as darkened areas of coast (from Edgar et al. 2009<br />
GCB).<br />
Nature based <strong>to</strong>urism selects for higher priority conservation sites but introduces bias in<br />
estimations of diversity compared <strong>to</strong> sites with less visitation.<br />
Threatened ahermatypic corals requiring additional levels of protection are often associated with the<br />
<strong>to</strong>urism sites that were chosen for their exposed high current and headland character that attracts a<br />
range of <strong>to</strong>urism target species, in particular pelagic animals. Where <strong>to</strong>urism zones appear <strong>to</strong> capture<br />
areas of higher endemism, some biasing probably exists due <strong>to</strong> the higher levels of diver visitation<br />
throughout recent years drawing attention <strong>to</strong> uncommon species in those areas.<br />
Until recently the significant loss of important habitat forming <strong>Galapagos</strong> species went<br />
unheralded.<br />
The loss of <strong>Galapagos</strong> macroalgae (at least 33% of <strong>Galapagos</strong> algae 90/300 species have yet <strong>to</strong> be<br />
recorded anywhere else) is significant and received little attention directly after the strong 1982/3 EN<br />
– since then a relatively small temperate ecosystem under the equa<strong>to</strong>rial sun, sustained by<br />
constitutive upwelling has fostered endemic kelp Eisenia galapagensis, rediscovered in 2004 and<br />
further documented in 2007 as a distinct GMR habitat new <strong>to</strong> marine science on the equa<strong>to</strong>r.<br />
El Niño and La Niña die‐offs and slow vs. rapid benthic recruiters generate a constant flux<br />
in the composition of the benthic productive environment.<br />
Following moderate‐ strong El Niño events, cold productive La Niña switches foster rapid recovery of<br />
some species such as subtidal barnacles, Ulva and Enteromorpha species competing with coral and<br />
other established sessile macrofauna. Coralline encrusting algae likely play an important persistent<br />
role in reef accretion during such events, yet have yet <strong>to</strong> be properly investigated.<br />
15
6. TECHNOLOGICAL ADVANCES TO EARLY THREAT DETECTION<br />
<strong>Galapagos</strong> is a globally unique field labora<strong>to</strong>ry for assessing the response of taxa and<br />
effect of management measures under extreme oceanographic events commensurate in<br />
some aspects <strong>to</strong> global warming scenarios over different time scales.<br />
Although many ENSO impacts are reasonably well documented, important information gaps as <strong>to</strong> the<br />
<strong>Galapagos</strong> ocean‐climate dynamic still exist. Particularly relevant is determination of threshold levels<br />
for switches in the <strong>Galapagos</strong> climate system (i.e. at which point does a NOAA El Niño in the EN 3<br />
zone become a <strong>Galapagos</strong> El Niño with cascading trophic deprivation effects etc., what degree of<br />
thermocline depression prevents Equa<strong>to</strong>rial Undercurrent upwelling in<strong>to</strong> sunlit surface water and<br />
over what scales etc.). Ongoing climate research looks <strong>to</strong> determine which interactions are the most<br />
sensitive and applicable as indica<strong>to</strong>rs and what is the spatial variability at small scales relevant <strong>to</strong><br />
conservation management and protection of small threatened species populations.<br />
The <strong>Galapagos</strong> Ocean Observing System: a need for a decision support system with<br />
integrated information management.<br />
Despite a lot of groundwork, <strong>Galapagos</strong> still requires an information management system<br />
appropriately feeding back <strong>to</strong> management based around an ecosystem level and robust moni<strong>to</strong>ring<br />
framework with a “legacy” mechanism in place <strong>to</strong> ensure its continuity that also encourages best use<br />
of competencies between local institutions.<br />
7. CORAL / ROCKY REEF HEALTH DIAGNOSTICS<br />
Rate of change as well as the magnitude of climatic events affects coral health.<br />
Cold water shock (through internal wave propagation rapidly pushing segregated deep water over<br />
the <strong>Galapagos</strong> platform and exposed oceanic pinnacles in<strong>to</strong> the solar heated mixed surface layer) is<br />
as much a stress <strong>to</strong> subtidal environments as gradual warming. Exaggerated temperature differentials<br />
and rates of temperature change have caused extensive bleaching responses. A moderate EN event<br />
in early 2007 followed by sharp cold upwelling transitions of 11 ° C over 10m depth subtidal reef over<br />
6 days paved the way in<strong>to</strong> a LN that compounded extensive cold water bleaching of Porites and<br />
Pocillopora corals (Banks 2009, Glynn et al. 2009, Witman et al. 2003; submitted 2009) as the cold<br />
season developed in<strong>to</strong> late 2007. Both the interval between strong ENSO events and rate of change<br />
from ENSO SST maxima <strong>to</strong> minima as well as generating a strong bleaching response, presumably also<br />
indirectly impact the level of bioerosion of the reef following strong events and aperture for coral<br />
framework recovery.<br />
Both warm water stress and cold water shock affect <strong>Galapagos</strong> corals <strong>to</strong> degrees dependent upon<br />
largely unqualified interactions with a range of covariates; physically driven shifts in associated<br />
communities and trophic modalities, fisheries extraction of reef preda<strong>to</strong>rs, transmission of diseases<br />
and their agents etc.<br />
Relative abundances of bioeroders and grazers indicate regime shifts in habitat forming<br />
reef.<br />
16
Reduced habitat complexity (reef <strong>to</strong> rubble) seems a direct consequence of bioerosion and<br />
overgrazing making urchin barrens ubiqui<strong>to</strong>us across the reserve since the last strong ENSO events of<br />
1982/3 and 1997/8. The pencil urchin Eucidaris galapagensis for example doubled in numbers from<br />
1982 <strong>to</strong> 1984 (pseudo‐pho<strong>to</strong>quadrat data standardized from marine pho<strong>to</strong>s). Major ecosystem level<br />
changes occurred during these periods as a result and populations do not appear <strong>to</strong> have recovered<br />
(Edgar et al. 2009). In the intertidal zone large fucoid algaes such as Bifurcia galapagensis<br />
disappeared presumably redefining available nursery habitat for many associated species. Patterns of<br />
benthic cover from pho<strong>to</strong>graphic surveys show remarkable correlation from 1984 and 2004, yet are<br />
distinctly different from 1982 emphasizing that despite the absence of other data during the period,<br />
changes in habitat forming species were very significant.<br />
Nonetheless in intervening years there are some signs of recuperation in the 1‐5% of reef frameworks<br />
that persisted. Glynn reports recovery of bleached tissue in certain northern reefs since 2000 and<br />
new recruits from the same locality in the most extensive Darwin reef with a largely intact accreted<br />
framework.<br />
There is likely a threshold level of urchin abundance (principally Eucidaris) at which reestablishment<br />
of coral and macroalgal habitat is limited resulting in a semi‐permanent regime shift. We have yet <strong>to</strong><br />
determine those thresholds as indica<strong>to</strong>rs of a regression <strong>to</strong> a lower diversity habitat state. An<br />
averaged 3.2 individuals / m 2 abundance seems indicative of urchin barren development in the<br />
central islands, while densities
include a careful appraisal of open water fishery options <strong>to</strong>wards species that may benefit from a<br />
climate shift such as tuna, wahoo etc. and/or a more appropriate redistribution of the vast equity<br />
wrapped up in <strong>Galapagos</strong> nature based <strong>to</strong>urism.<br />
Well managed <strong>to</strong>urism zones promote protection of high diversity sites.<br />
Tourism areas concentrate around species rich areas with many endemics hence conservation and<br />
nature based <strong>to</strong>urism tend <strong>to</strong> select for the same areas. They also have the advantage of assigning a<br />
$$ value distinct from fisheries and lend a kind of passive vigilance preventing at least in popular sites<br />
fisheries infractions. There is incentive <strong>to</strong> respect zone use as growing market awareness and<br />
advocacy for “best <strong>to</strong>urism practices” become selling points for nature based <strong>to</strong>urism agencies and<br />
ideals are appropriated by <strong>Galapagos</strong> naturalist guides. Although difficult <strong>to</strong> quantify presumably<br />
illegal line fishing from <strong>to</strong>urism vessels has reduced in recent years. On site impact is considered <strong>to</strong> be<br />
low (compared <strong>to</strong> the associated high impact development and invasive species risk indirectly<br />
stimulated by <strong>to</strong>urism), although anchor damage and continuous small hydrocarbon spills and<br />
pollution through constant visitation is potentially problematic.<br />
Ambiguity in interpretation of new fisheries/ <strong>to</strong>urism alternatives.<br />
There exists considerable ambiguity in interpretation/application of recent alternatives such as pesca<br />
vivencial (a form of potentially low impact high return fisheries based <strong>to</strong>urism) which appears from<br />
informal accounts <strong>to</strong> be heavily subsidized by external interests under local captain endorsement and<br />
approaches a full sports fishing activity. These loop holes in the existing legal and management<br />
framework need <strong>to</strong> be clarified. They are often seemingly intractable governance problems that we<br />
must work around and with advocacy agencies if we cannot confront them directly.<br />
V. CAPACITY BUILDING AND OUTREACH<br />
1. We posted a blog linked <strong>to</strong> our moni<strong>to</strong>ring work currently posted by NASA at:<br />
http://oceancolor.gsfc.nasa.gov/staff/gene/galapagos.html. A summary of materials<br />
from each participant is included in Annex 2. As <strong>Science</strong> <strong>to</strong> <strong>Action</strong> activities continue in<strong>to</strong><br />
2010 we plan <strong>to</strong> use some of these biopics and project descriptions as awareness/<br />
<strong>Galapagos</strong> science for conservation materials for local school groups.<br />
2. During the last research expeditions (July 2009) video footage was taken by BBC<br />
<strong>Galapagos</strong> film maker <strong>to</strong>wards two short 3‐6 min montage sequences of moni<strong>to</strong>ring<br />
activities (copies with CI Scott Henderson).<br />
3. <strong>Galapagos</strong> participation for key conservation messages continues with the Integration<br />
and Application Network (I.A.N) process coordinated by CI <strong>to</strong>wards the global node<br />
synthesis S2A outreach products. These are 1) MMAs: What and Why; 2) <strong>Science</strong> <strong>to</strong><br />
<strong>Action</strong> 101; 3) People and Oceans; and 4) Living with the Sea. We expect that some of<br />
these products will be transferable locally in <strong>Galapagos</strong> in 2010.<br />
18
4. Outreach was also approached through a combination of local talks and guide courses (22<br />
hours over 11 weeks from Sept‐Oct 2009). With counterpart support we also produced 10<br />
marine themed CDF talks in the <strong>Galapagos</strong> <strong>Science</strong> symposium of July 2009, and produced a<br />
variety of poster materials for future outreach events, including a generic poster outlining<br />
current CDF ecological research level research (Figure 2).<br />
5. CDF scientists ran a series of science writing, trophic modeling, fisheries evaluation methods,<br />
ecological moni<strong>to</strong>ring, moni<strong>to</strong>ring design, statistics, basic GIS, climate‐fisheries modeling,<br />
biodiversity and collections and coastal vertebrate moni<strong>to</strong>ring courses through 2008 and<br />
2009. Although participation was intermittent (~30 days) Park officials were encouraged <strong>to</strong><br />
attend all events and we intend <strong>to</strong> continue with such courses in<strong>to</strong> 2010.<br />

ANNEX ONE: STANDARDIZED SURVEY PROCEDURES FOR MONITORING REEF<br />
ECOSYSTEMS IN THE EASTERN TROPICAL PACIFIC<br />
INTRODUCTION<br />
We here describe methods for estimating densities of fishes, large macroinvertebrates, sessile<br />
invertebrates, and seaweeds on reefs. This method has now been applied during surveys undertaken<br />
in four countries of the Eastern Tropical Pacific region – Ecuador, Colombia, Panama and Costa Rica<br />
(Edgar et al. 2004a). Many hundreds of sites have now been surveyed using these methods, with<br />
variants of the method involving different transect replication applied globally (e.g., Barrett & Bux<strong>to</strong>n<br />
2002, Edmunds & Hart 2003, Edgar et al. 2004b).<br />
Visual census techniques provide the most effective way <strong>to</strong> moni<strong>to</strong>r species at shallow‐water sites<br />
because large amounts of data on a broad range of species can be collected within a short dive<br />
period, with little post‐processing time required. In addition, moni<strong>to</strong>ring programs associated with<br />
marine protected areas (MPAs) should be non‐destructive. MPA surveys need <strong>to</strong> cover a range of<br />
taxa because, in addition <strong>to</strong> heavily‐exploited species that are predicted <strong>to</strong> recover in no‐fishing<br />
MPAs, significant flow on effects associated with increased preda<strong>to</strong>r numbers may occur that would<br />
otherwise go undetected. For analysis of subtle long‐term trends, site‐<strong>to</strong>‐site variation should be<br />
minimized by re‐surveying the same sites at different times, with surveys repeated whenever<br />
possible in the same month in different years <strong>to</strong> minimise seasonal effects.<br />
The reef survey technique described here was designed <strong>to</strong> maximise the amount of ecological<br />
information related <strong>to</strong> all conspicuous taxa that can be obtained during a dive with a single tank of<br />
air, based on a 2‐3 person dive team. Two depth strata at three sites can comfortably be surveyed<br />
per day by a team of three divers, weather conditions permitting.<br />
The basic unit moni<strong>to</strong>red is a 50 m long transect line. The width of transect blocks varies with<br />
different major taxonomic groupings surveyed (large fish, cryptic fish and macroinvertebrates, and<br />
sessile invertebrates and seaweeds), with coincident information relating <strong>to</strong> all taxa obtained along<br />
each line.<br />
Because data, particularly for fishes, can vary with relatively slight changes <strong>to</strong> pro<strong>to</strong>cols (e.g. with<br />
different transect band width or diver swimming speed), it is important that these methods are<br />
consistently applied. Data generated are most usefully applied in a relative sense (ie, for comparing<br />
one site with another or one time with another when data are collected using the same methods –<br />
Lincoln Smith 1988, Lincoln‐Smith & 1989), but will likely be inaccurate (and many caveats will be<br />
required with respect <strong>to</strong> biases) if used <strong>to</strong> try <strong>to</strong> estimate the size of the <strong>to</strong>tal fish community on reefs<br />
(Kulbicki 1998, Edgar et al. 2004b).<br />
21
Data collected by different divers on a field trip should be compared for consistency as soon as<br />
possible, particularly during the early surveys. Thus, for example, if two divers are collecting fish<br />
information then their data should be compared after dives. Ideally, all divers should survey the same<br />
site and depth on the first sampling occasion, then data compared before other dive sites are visited.<br />

HOW IT WORKS<br />
• At each site a diver records data by initially swimming along a defined depth con<strong>to</strong>ur with a<br />
50 m transect line unravelling behind.<br />
• The following scientific information is collected:<br />
o Fishes are surveyed in two 5 m wide bands, up and back in parallel with the 50 m<br />
transect line.<br />
o Invertebrates and cryptic fish are surveyed in two 1 m wide bands on either side of<br />
the transect line (1m x 50 m per transect).<br />
o Quadrats are placed at 5 m spacing along the transect line (i.e. 10 per 50 m transect)<br />
<strong>to</strong> quantify percentage cover of sessile invertebrates and macroalgae, and/or digital<br />
pho<strong>to</strong>graphs are taken in these positions.<br />
• Transects are reeled in when the work has been completed.<br />
• At least two (and up <strong>to</strong> four) depth con<strong>to</strong>urs are usually surveyed at each site (6 m and 15 m<br />
when possible, but always with one transect >10 m and another

METHODS<br />
Prior <strong>to</strong> all surveys, dive teams require clear diver safety procedures, both <strong>to</strong> minimize the risk of<br />
problems developing, and so that participants all know what actions are required if an accident does<br />
occur. In almost all cases, reef moni<strong>to</strong>ring in the Eastern Tropical Pacific is undertaken at considerable<br />
distance from hyperbaric chambers, hence safety margins should be fac<strong>to</strong>red in<strong>to</strong> all dive plans.<br />
FISH SURVEYS<br />
One diver firstly ties off the end of a 50 m transect line <strong>to</strong> the seabed then swims out, with the reel<br />
unwinding behind, along the deeper (>10 m) depth con<strong>to</strong>ur at a site. The number and estimated sizecategory<br />
of all fishes sighted within 2.5 m of the transect is recorded as the diver swims out the line.<br />
The transect block thus encompasses a <strong>to</strong>tal reef area of 50 m x 5 m.<br />
Th diver next censuses an adjacent replicate block by swimming back parallel <strong>to</strong> the initial transect at<br />
a distance of 5‐8 m upslope from the initial transect line. This up and back procedure for two<br />
adjacent blocks is repeated along the shallow (
MACROINVERTEBRATE AND CRYPTIC FISH SURVEYS<br />
Large macro‐invertebrates (large molluscs, echinoderms and crustaceans) and cryptic fishes (ie.<br />
inconspicuous fish species closely associated with the seabed that were likely <strong>to</strong> be overlooked<br />
during general fish surveys) are censused along the same transect lines set for fish surveys. A diver<br />
swims along the deeper side of the transect, counting all macroinvertebrates within 1 m of the line,<br />
then returns along the shallow side of the line counting animals within the adjacent 50 m x 1 m block.<br />
Data for the two blocks are recorded separately.At locations where large numbers of<br />
macroinvertebrates (particularly sea urchins) are present, divers should write down data on the<br />
underwater slate at least each 5 m along the transect line.<br />
SESSILE BENTHOS SURVEYS<br />
Information on the percentage cover of sessile animals and seaweeds along the transect lines set for<br />
fish and invertebrate censuses are moni<strong>to</strong>red by recording plant and sessile animal species within 0.5<br />
x 0.5 m quadrats placed sequentially each 5 m along the 50 m transect. Digital pho<strong>to</strong>quadrats are also<br />
taken vertically‐downward each 5 m along transect lines from a height sufficient <strong>to</strong> encompass an<br />
area of at least 0.5 m x 0.5 m. The scale of each pho<strong>to</strong>quadrat is evident from centimeter markings<br />
along the transect line, so it is not necessary <strong>to</strong> place a physical quadrat when pho<strong>to</strong>s are taken. The<br />
percentage cover of different macroalgal, coral, sponge and other attached invertebrate species in<br />
pho<strong>to</strong>quadrats are digitally quantified in the labora<strong>to</strong>ry using computer software.<br />
CORAL ECOLOGY AND HEALTH INDICATORS<br />
Some indica<strong>to</strong>rs of coral health can be tracked using digital pho<strong>to</strong>quadrats; however, more detailed<br />
information relating <strong>to</strong> coral growth, survival, recruitment and health is needed for areas with dense<br />
coral growth.<br />
Long term data on trends in coral metrics have been collected in the ETP by Hec<strong>to</strong>r Guzman and Jorge<br />
Cortez (Panama and Costa Rica), Alber<strong>to</strong> Rodriguez (Colombia), Peter Glynn and Joshua Feingold<br />
(<strong>Galapagos</strong> and Panama), and, more recently, by CDRS (<strong>Galapagos</strong>). Methods used by different<br />
groups differ somewhat, hence a comparative studies of methods is needed <strong>to</strong> permit regional<br />
analysis of coral metrics. An agreement on a core set of coral indica<strong>to</strong>rs <strong>to</strong> be moni<strong>to</strong>red region‐wide,<br />
with associated methods, remains an urgent priority.<br />
DIVISION OF LABOUR<br />
• Workload is divided between members of the dive team in a way that optimises efficiency<br />
and maximises the number of transects completed.<br />
• Division of tasks thus depends on the size of the team, who is skilled in what tasks, depth and<br />
survey location (some locations take longer for fishes compared <strong>to</strong> macroinvertebrates and<br />
vice versa).<br />
• In order of decreasing skill level required, the tasks are (i) survey sessile biota using quadrats,<br />
(ii) survey fishes, (iii) survey mobile macroinvertebrates, and (iv) take pho<strong>to</strong>quadrats and reel<br />
in line.<br />
• With a three person dive team, diver 1 generally reels out the transect line, surveys fishes up<br />
and back and then returns along the transect taking pho<strong>to</strong>quadrats, diver 2 surveys<br />
macroinvertebrates up and back, while diver 3 surveys sessile biota up the line then reels in<br />
24
the transect. If the fish person is relatively inexperienced, then the transect line can be laid<br />
out by someone else (e.g. the macroinvertebrates diver) so that the fish person can<br />
concentrate fully on censusing fishes.<br />
• With a two person dive team, diver 1 generally reels out the transect line, surveys fishes up<br />
and back, then returns along the transect taking pho<strong>to</strong>quadrats, and finally reels in the line,<br />
while diver 2 surveys macroinvertebrates up and back. The sessile biota is often not surveyed<br />
in situ in these circumstances, with analysis reliant on later digitisation of pho<strong>to</strong>quadrats.<br />
• When safety considerations warrant buddy divers remaining in close proximity, the diver pair<br />
should swim in parallel, swimming outwards surveying fishes in parallel bands with the<br />
deeper diver laying out the transect line, then returning either side of the transect line<br />
counting mobile macroinvertebrates and cryptic fishes, then up and back undertaking<br />
pho<strong>to</strong>quadrats, and finally reeling in the line.<br />
• Two transect depths can usually be accomplished in a single dive using the above methods,<br />
providing the first dive is
ends up parallel <strong>to</strong> itself make sure there is a least a 6 m gap. In some cases the reef edge will<br />
become progressively shallower, in which case it is best <strong>to</strong> stay inside the reef rather than<br />
extend the transect over sand. If a change in depth occurs, then the actual depth range of the<br />
transect should be recorded on data sheets (e.g. 3.8‐5.0 m rather than 5 m).<br />
DATA SHEET PROTOCOLS<br />
• Write words on data sheets as clearly as possible with printed letters.<br />
• Record the following header information: date, depth of transect, diver name, site name,<br />
time and underwater visibility (measure this out along the set transect line)<br />
• Record what transect you are working on and make a clear distinction (draw a line) between<br />
data belonging <strong>to</strong> different transects<br />
• Record frequency information as either a written number or by using tally lines in blocks of 5.<br />
Always distinguish between groups of numbers with commas, parentheses or underline (eg<br />
avoid 32 being interpreted as a 3+2) and take particular care with written 11 (eleven) as this<br />
looks identical <strong>to</strong> two 1 strokes. To avoid problems, eleven and other multiple digit numbers<br />
should be underlined on data sheets if there is any possibility of confusion.<br />
• Try and use recognised names for animals (preferably scientific but common names are fine).<br />
It is ok <strong>to</strong> make up your own naming conventions for species but make sure you are<br />
consistent and that you provide a key.<br />
• Data should be recorded digitally as soon as possible after the dive <strong>to</strong> improve accuracy and<br />
loss of important information (ie. before memory becomes fuzzy).<br />
• The roles of all participants in the team should be clearly defined, including a clear<br />
understanding of who is responsible for preparing and transporting equipment, and who is<br />
responsible for collating and checking data associated with each of the different survey<br />
methods.<br />
SURVEY EQUIPMENT<br />
• 50 m transect lines.<br />
• Quadrats – stainless steel 0.25 m 2 (7x7grid)<br />
• Catchbags – <strong>to</strong> fit slates, specimens etc.<br />
• Camera for pho<strong>to</strong>quadrats<br />
• Slates, pencils and waterproof paper<br />
• 1 m pole for judging invertebrate band (optional)<br />
• For a more comprehensive checklist of field equipment see final table. This includes GPS <strong>to</strong><br />
record site position.<br />
IMPORTANT THINGS FOR PEOPLE TO KNOW WHEN LEARNING FISH SURVEYS<br />
Target group All fish and other large swimming animals (eg squid, oc<strong>to</strong>pus, seals, turtles, whales etc)<br />
Technique<br />
• Establish the size of a 5 m band centred on the transect line. Divers swim along the middle of<br />
this band, but can move <strong>to</strong> the right or left <strong>to</strong> search caves, etc. [As a reference, the distance<br />
of 2.5 m is approximately the length of a tall diver with arm outstretched in front from fin tip<br />
<strong>to</strong> finger tip. ]<br />
26
• Swim slowly approximately 1 m off of the bot<strong>to</strong>m looking side <strong>to</strong> side and up and down. If<br />
underwater visibility is low, then the maximum visibility can be used as a subsampling unit.<br />
Thus, if the visibility is, for example, 5 m then the diver should write down information on<br />
data sheets every 5 m, before progressing along the next 5 m, etc.<br />
• Record the size and frequency of fish species seen.<br />
• If identification is not possible, then draw a picture, take a pho<strong>to</strong>graph and/or write a<br />
descriptive note (the more information the better). Be sure <strong>to</strong> ask others/check books at the<br />
end of the dive.<br />
• Where fish are schooling estimate abundance by counting a block and then multiplying by<br />
size of school.<br />
• Record estimated size of fish using the following size classes:<br />
cm 2.5 5 7.5 10 12.5 15 20 25 30 35 40 50<br />
Inches 1 2 3 4 5 6 8 10 12 14 16 20<br />
• The length of fish larger than 50 cm should be estimated <strong>to</strong> the nearest 12.5 cm and<br />
individually recorded.<br />
• When it is impossible <strong>to</strong> record counts for all fishes seen, the highest priority is <strong>to</strong> record<br />
names of all fish species seen on each transect, then abundance of large species, then<br />
abundance of small species, then size classes of each species.<br />
• <strong>Galapagos</strong> variant – Fish surveys in <strong>Galapagos</strong> have traditionally been undertaken by a diver<br />
not involved in fish counts initially laying the transect line, and then the two 5m x 50 m<br />
transect blocks are surveyed for fishes by one diver swimming up and back along the line.<br />
Thus, the two blocks are contiguous with no gap between.<br />
Other<br />
• Record separate data for males and females where there is an obvious sex difference in<br />
fishes.<br />
• Look under overhangs and in caves within the 5 m wide band. Record fish such as<br />
damselfishes that live in cave habitat by peering in from the cave entrance, but don’t enter.<br />
• Avoid counting fish when there are other divers in close proximity as this can affect fish<br />
counts. [Plan dives so fish counts can be done with minimal disturbance.] If sealions or other<br />
large marine mammals are around, then make sure that their presence is noted on data<br />
sheets since this can greatly affect the fish survey.<br />
• Don’t count fish that overtake you.<br />
If you recognise the same fish in your area of count while swimming on transects up and back (i.e see<br />
a fish twice that has obviously moved across the transect line), record this animal both times. [This<br />
balances out other fish that moved across the line in the opposite direction, and were not counted.]<br />
How <strong>to</strong> deal with situations, such as coral rich areas, where diverse communities of fishes are seen<br />
swimming in all directions and you feel overwhelmed<br />
At some sites, trying <strong>to</strong> assess the abundance of fish life may seem extremely daunting. These situations<br />
are, however, manageable if you recognise that it will be impossible <strong>to</strong> count all the fishes, and that for the<br />
27
most abundant species estimates will be necessary. As the diver swims along, data should be written down<br />
in order of priority:<br />
Highest priority is the <strong>to</strong>tal species list for the transect. Thus, if a diver sights a species of fish<br />
previously unrecorded on the transect, this should be written down immediately.<br />
Second priority is the abundance of large and rare fishes. The numbers of any large, rare and/or<br />
commercially important fish should be written down as these are sighted. If a school of say jacks swims<br />
past, then the <strong>to</strong>tal numbers in a small section of that school should be counted and multiplied by an<br />
estimate of what proportion of the <strong>to</strong>tal school that section comprises.<br />
Third priority is the number of common small fishes. This number is usually estimated rather than<br />
counted directly. It is important <strong>to</strong> recognise that numbers recorded in transects will be log<br />
transformed in most statistical analyses, hence whether you record 300 or 400 of a species will make<br />
little difference <strong>to</strong> interpretation of data. Thus, don’t be overly concerned about accurately counting<br />
numbers of say damselfish in a flock. For extremely abundant species, it is often sufficient <strong>to</strong> ignore<br />
these while swimming along the transect other than writing down the species name, then at the end<br />
count the number in say a 1 m wide block that extends 5 m along the transect line, then multiply that<br />
number by 50 <strong>to</strong> get numbers for the 50 m x 5 m wide transect block, adjusting up and down a bit for<br />
whether the number in the area counted seems more or less than the average for the whole transect<br />
length.<br />
Fourth and lowest priority is the size‐distribution. This should be done as accurately as possible for<br />
the large commercial species, but for others size structure is often assessed by partitioning <strong>to</strong>tal<br />
abundance counts. For example, you may estimate 400 blue‐spotted damselfish for the transect<br />
length, then think that about half were in the 75 mm size class, with about 10 animals in the 100 mm<br />
size class and the rest evenly divided between the 50 mm and 25 mm classes – making 10 at 100 mm,<br />
200 at 75 mm, 95 at 50 mm and 95 at 25 mm when written down.<br />
Converting fish abundance estimates <strong>to</strong> biomass<br />
Fish abundance counts and size estimates can be converted <strong>to</strong> biomass estimates using length‐weight<br />
relationships presented for each species (in some cases genus and family) in Fishbase<br />
(http://www.fishbase.org/search.php). Note that these length‐weight relationships are sometimes<br />
described in terms of standard or fork length rather than <strong>to</strong>tal length (as recorded by divers); however,<br />
equations for converting between the different length parameters are also included in Fishbase. For<br />
best accuracy in biomass assessments, the bias in divers’ perception of fish size underwater should be<br />
corrected using equations presented in (Edgar et al. 2004b).<br />
Note that estimates of fish abundance made by divers can be greatly affected by fish behaviour for<br />
many species (Edgar et al. 2004b); consequently biomass determinations, like abundance estimates,<br />
28
can reliably be compared only in a relative sense (ie for comparisons with data collected using the<br />
same methods) rather than used <strong>to</strong> provide an absolute estimate of fish biomass for a patch of reef.<br />
IMPORTANT THINGS FOR PEOPLE TO KNOW WHEN LEARNING INVERTEBRATE SURVEYS<br />
Target group<br />
• All ‘large’ mobile invertebrates and cryptic fish are counted. ‘Large’ invertebrates are defined<br />
as animals that are more than 2.5 cm (approximately 1 thumb tip) when mature. Species<br />
counted include large gastropods (including nudibranchs), crinoids, sea cucumbers, sea stars,<br />
sea urchins, lobsters and large crabs. Cryptic fish are those closely associated with seaweeds<br />
or the seabed such as gobies, blennies, threefins, cardinalfishes, scorpionfishes, frogfishes,<br />
catsharks, rays, and moray eels. Fishes not regarded as cryptic, hence not counted on these<br />
surveys, include wrasses and damselfishes.<br />
Technique<br />
• Stay close <strong>to</strong> the bot<strong>to</strong>m and push aside any large seaweeds <strong>to</strong> reveal the substratum.<br />
• Record abundance of all invertebrates and cryptic fish in 1 m bands on each side of the<br />
transect line.<br />
• Estimate size of cryptic fish using the same size categories as for large fish.<br />
• Search all crevices and cracks but do not turn over rocks or boulders.<br />
• If identification is not possible make a note on your data sheet, put the specimen in your<br />
catch bag and ask others or check books at the end of the dive when on the boat, then return<br />
the animal <strong>to</strong> the sea.<br />
IMPORTANT THINGS FOR PEOPLE TO KNOW WHEN LEARNING SURVEYS OF SESSILE BIOTA<br />
USING QUADRATS<br />
Target group<br />
All algae, sessile invertebrates and substratum categories<br />
Technique<br />
• Ten quadrats are sampled along each 50 m transect<br />
• Quadrats are placed at 5 m intervals, at 5, 10, 15, 20, 25, 30, 35, 40, 45 and 50 m marked<br />
positions on the transect line.<br />
• The number of contact points that algae, corals or bare substratum have with the 50<br />
intersection points on quadrat is recorded once the quadrat has been placed in position.<br />
Contact points consist of the 49 quadrat intersection points plus one corner – see Figure<br />
4.Alternatively, 0.5 m x 0.5 m quadrats with line spacing every 50 mm can also be used. These<br />
possess 81 intersection points, with data converted <strong>to</strong> percentage figures by multiplying by<br />
100/81.<br />
• Count all layers of algae. This is done by counting the canopy species, then brushing these<br />
aside <strong>to</strong> count what is underneath on the substratum.<br />
• Try <strong>to</strong> identify coral and other sessile invertebrates and algae <strong>to</strong> species; if this is not possible<br />
then <strong>to</strong> genus.<br />
29
• If identification <strong>to</strong> species or genus is not possible while underwater then make a note on<br />
your data sheet, take a sample (try and get an entire plant) and ask others/check books at the<br />
end of the dive. You may also press the alga for future reference if you have the appropriate<br />
scientific collecting permit.<br />
• Use accepted grouping categories if the species cannot be positively identified (see Table 1<br />
below for substratum categories; Table 2 for algae and Table 3 for sessile invertebrates).<br />
Count everything that<br />
occurs directly under these<br />
81 intersection points plus<br />
1 corner.<br />
Figure 2. Diagram of quadrat used in sessile biota surveys.<br />
Pho<strong>to</strong>quadrats<br />
• Pho<strong>to</strong>quadrats are centred on the transect line. A physical quadrat is not required because<br />
size information is evident from markings on the transect line.<br />
• Pho<strong>to</strong>quadrats should be digitally labelled as soon as possible, with transect depth, date and<br />
site.<br />
• A pho<strong>to</strong> should be taken at the start of the pho<strong>to</strong>quadrat run along each transect showing<br />
the divers depth gauge or dive computer (for permanent record of depth).<br />

ANNEX TWO: ECOLOGICAL SUBTIDAL MONITORING FIELD BLOGS<br />
THEMED ENTRIES: INTRODUCED BY DR GENE FELDMAN, NASA OCEAN COLOUR PROGRAM<br />
Taken over a one week moni<strong>to</strong>ring trip in August 2009, various moni<strong>to</strong>ring activities and the reasoning<br />
behind them are described by an observers perspective (Gene Feldman) and through personal accounts<br />
from those directly involved.<br />
1. OCEAN SAMPLING.<br />
In this day of high speed computers, sophisticated satellite observation systems and the continuously<br />
connected world in which we do our science, it has been quite a eye opening and muscle straining<br />
experience <strong>to</strong> realize that people still do oceanographic research the old fashioned way — by hand! The<br />
ocean waters around the <strong>Galapagos</strong> teem with life and nowhere is the abundance of phy<strong>to</strong>plank<strong>to</strong>n,<br />
those microscopic floating plants that form the base of the marine food web and essentially support all<br />
life in the oceans greater, than in the western part of the Archipelago, exactly where our cruise has<br />
taken us. Supported by the nutrient‐rich upwelling of the eastward flowing Equa<strong>to</strong>rial Undercurrent also<br />
known his<strong>to</strong>rically as the Cromwell Current, and as some believe, fertilized by the iron‐rich<br />
micronutrients that these volcanic islands have in abundance, the waters between Fernandina and<br />
Isabela have some of the highest phy<strong>to</strong>plank<strong>to</strong>n concentrations anywhere. The waters are literally<br />
green, more closely resembling a diluted pea soup than the deep blue ocean waters that most people<br />
associate with the open sea.<br />
Image depicting clorophyll‐a concentration<br />
34
Feeding at this twenty four hour a day all you can eat buffet of phy<strong>to</strong>plank<strong>to</strong>n, the tiny animals<br />
that form the next step in the marine food web, the zooplank<strong>to</strong>n, are also so abundant that<br />
they can often be seen with the naked eye, especially the ones that seem <strong>to</strong> have swallowed<br />
little drops of phosphorescent paint in shades of green, blue, yellow and purple. As interesting<br />
as they may be <strong>to</strong> look at, <strong>to</strong> quantify the concentrations of these two critical components of<br />
the marine food web in this incredibly rich and dynamic system, we resort <strong>to</strong> an age old<br />
technique of dragging very fine mesh nets through the water and seeing what we catch. Since<br />
this work is done from one of the little inflatable pangas, it means that everything has <strong>to</strong> be<br />
done by hand which is not <strong>to</strong>o bad when letting out the several hundred feet of rope tied <strong>to</strong> the<br />
end of the two plank<strong>to</strong>n nets that we use. However, when it comes time <strong>to</strong> haul the nets back<br />
<strong>to</strong> the boat, what you have at the end of a very long rope is essentially a giant bag filled with<br />
very heavy water.<br />
An age old technique of dragging very fine mesh nets through the water <strong>to</strong> capture<br />
phy<strong>to</strong>plank<strong>to</strong>n and zooplank<strong>to</strong>n.<br />
35
Cruising along in an inflatable panga, dragging nets.<br />
To catch both the phy<strong>to</strong>plank<strong>to</strong>n and zooplank<strong>to</strong>n we use two different nets, one tied off <strong>to</strong><br />
each side of the panga, one a very fine mesh net that is designed specifically <strong>to</strong> trap the<br />
microscopic phy<strong>to</strong>plank<strong>to</strong>n near the surface and the other has a little bit larger mesh that will<br />
let the phy<strong>to</strong>plank<strong>to</strong>n pass through but catch the larger zooplank<strong>to</strong>n as it is pulled through the<br />
water. Whatever organisms do not pass through the mesh are trapped at the end of the net<br />
and ultimately end up in a little mesh‐lined bottle.<br />
Collecting chlorophyll‐a<br />
36
Collecting zooplank<strong>to</strong>n<br />
The differences between the contents of the two nets, both having been pulled at a depth of<br />
one meter for ten minutes is really quite remarkable. The water from the larger meshed net<br />
was essentially crystal clear except that it was filled with all sorts of incredible looking<br />
creatures, many of them eagerly swimming around in their little plastic bottle. There were at<br />
least a few larvae fish and many shrimp‐like zooplank<strong>to</strong>n with large black eyes that jerked their<br />
way through the water as they contracted their bodies in the unfamiliar surroundings. The<br />
smaller meshed yielded a chlorophyll‐a rich phy<strong>to</strong>plank<strong>to</strong>n filled jar that was impossible <strong>to</strong> see<br />
through and thankfully for those of us who have made a career of it, reaffirms the basic<br />
premise behind all ocean color remote sensing — that the color of the ocean is largely<br />
determined by the concentration of phy<strong>to</strong>plank<strong>to</strong>n in the near‐surface waters and this color<br />
can be detected from space. I can’t wait <strong>to</strong> get back <strong>to</strong> shore and see what SeaWiFS “saw” as it<br />
flew over the <strong>Galapagos</strong> <strong>to</strong>day at the same time that we were pulling our nets through the<br />
water, 700 kilometers below.<br />

2. LIFE IS MUCH BETTER, DOWN WHERE IT’S WETTER, UNDER THE SEA!<br />
I’ve asked Stuart <strong>to</strong> write a short description of the scientific background behind the dive<br />
program that is at the heart of the research cruise that I have been fortunate enough <strong>to</strong><br />
participate in and that description can be found at the bot<strong>to</strong>m of this journal entry. However, I<br />
wanted <strong>to</strong> try and graphically illustrate what these amazing folks have done three times a day,<br />
every day of this cruise regardless of conditions.<br />
The Mabel<br />
People may think that diving on the equa<strong>to</strong>r must be a pleasure and that all you have <strong>to</strong> do is<br />
strap on a tank, put on some flippers and a mask and jump over the side. In reality, because of<br />
the cold upwelled waters of the equa<strong>to</strong>rial undercurrent, particularly in the western part of the<br />
Archipelago, it is really hard and bone chilling work. I’ve watched as the two teams of divers<br />
somehow manage <strong>to</strong> stuff themselves in<strong>to</strong> two layers of neoprene with boots and hoods and<br />
gloves — certainly not what one would expect <strong>to</strong> wear for diving on the equa<strong>to</strong>r. However,<br />
even with all this, the divers emerge after nearly an hour and a half under water with their lips<br />
a nice shade of blue and shivering under the hot equa<strong>to</strong>rial sun. I’ve watched as they’ve draped<br />
their arms and legs around the sides of the pangas, trying <strong>to</strong> capture any bit of heat that the<br />
dark rubber hulls may have absorbed from the sun, looking remarkably like the marine iguanas,<br />
basking on the black volcanic rocks after they have spent a much shorter time underwater<br />
grazing on the beds of algae.<br />
So here is what a typical day is like for the scientists/divers onboard the M/V Queen Mabel as<br />
I’ve watched them over the past week although, I can’t imagine that diving in such an incredible<br />
place with such amazing marine life all around you could ever be considered “typical”.<br />

The Panga Drivers<br />
After taking the divers <strong>to</strong> the dive site, the panga drivers try and maintain their positions above<br />
the divers, keeping an eye on their bubbles and standing by in case there are any emergencies.<br />
If all goes well, and I speak of this from personal experience after having kept them company<br />
for a number of dives, being what I like <strong>to</strong> call “shake and baked” for the nearly hour and a half<br />
that the divers are down, the divers surface, raise their arms and the panga driver races over <strong>to</strong><br />
39
pick them up, help lift their tanks and gear aboard and takes them back <strong>to</strong> the Mabel as quickly<br />
as he possibly can.<br />

Suiting Up — With a Little Help from a Friend<br />
As mentioned above, diving in most parts of <strong>Galapagos</strong> is not what you’d expect and a great<br />
deal of time is spent by the divers in trying <strong>to</strong> fend off the effects of the numbingly‐cold<br />
upwelled water of the equa<strong>to</strong>rial undercurrent that bathes the western parts of the<br />
Archipelago. Trying <strong>to</strong> insert oneself in<strong>to</strong> two layers of neoprene wet suits is not easy and is<br />
similar in many respects <strong>to</strong> the extrusion of sausage in<strong>to</strong> its casing, only without the help of a<br />
machine. Getting that last zipper zipped more often than not requires the help of at least one<br />
and many times, two friends.<br />

Heading Out <strong>to</strong> the Dive Sites<br />
After having made sure that all the gear they will need has been placed onboard the pangas,<br />
the teams head off <strong>to</strong> their respective sites finding their locations through a combination of<br />
visual memory and a hand‐held GPS receiver. It is critical <strong>to</strong> the goals of this program that the<br />
same sites are revisited as closely as possible so that changes over time can be correctly<br />
assessed.<br />
Heading out<br />
After they arrive at the site, final checks of gear are made, regula<strong>to</strong>rs tested, masks defogged,<br />
measuring tapes, writing slates and sampling bags are gathered up and on the count of three,<br />

the divers fall backwards in<strong>to</strong> the water, purge the air from their buoyancy vests and sink<br />

Assuming that everything has gone well, the first diver surfaces approximately eighty <strong>to</strong> ninety<br />
minutes after submerging and the panga driver races over <strong>to</strong> meet the divers as they emerge<br />
and helps them back in<strong>to</strong> the pangas and back <strong>to</strong> the Mabel. Conversation in the panga on the<br />
42
eturn trip is minimal compared <strong>to</strong> the trip out since everyone is cold, exhausted and just trying<br />
<strong>to</strong> focus on something other than their shivering bodies.<br />

The empty yet still very heavy air tanks are lifted from the bouncing pangas over the rail and<br />
even heavier filled ones are passed down <strong>to</strong> take their place for the next dive. Dive suits are<br />
peeled off, rinsed and hung <strong>to</strong> dry for a few hours, the divers rinse off with the cold water foot<br />
pump shower on the dive platform, data from the dive are entered in<strong>to</strong> everyone’s computer,<br />
Angela sorts through the little plastic bags of invertebrate specimens and identifies them with<br />
the aide of a reference book and the combined knowledge of the divers before placing them<br />
back in<strong>to</strong> the ocean. The empty air tanks and gas tanks for the pangas are refilled and before<br />
very long, it’s time <strong>to</strong> do it all over again.<br />

STUART BANKS’ DESCRIPTION OF THE DIVE PROGRAM<br />
Subtidal community moni<strong>to</strong>ring works <strong>to</strong> characterize the near coast underwater communities<br />
across the entire <strong>Galapagos</strong> Marine Reserve (GMR). It is part of a long‐term project <strong>to</strong> follow<br />
change in the coastal zone across the different bio‐geographic regions in the GMR, from the<br />
cold upwelled communities dominated by macro‐algae stands in the western islands, <strong>to</strong> the last<br />
remaining coral reefs in the far northerly islands of Wolf and Darwin. The overall goal is <strong>to</strong><br />
gauge how the marine reserve is changing between seasons, between years, under El Nino /<br />
Southern Oscillation (ENSO) and with different types of extractive (fisheries) and non extractive<br />
(<strong>to</strong>urism) activities. Every year we follow more than 64 fixed sites which were approved<br />
between all GMR stakeholders in 2004 in order <strong>to</strong> evaluate the effectiveness of the coastal<br />
45
zoning — one of the principal management <strong>to</strong>ols applied by the national park service in the<br />
reserve.<br />
What that means in practice is a LOT of dive work. Two groups of 3‐4 people simultaneously<br />
dive at replicate sites over 22 field days per season which works out at around 40 hours spent<br />
underwater per diver, or 240 diver‐hours in <strong>to</strong>tal (10 days!) for the 6 person team. Each diver is<br />
specialized in 2 types of moni<strong>to</strong>ring. Laying 50m parallel transects out at 15m and 6m depths<br />
that follow the bathymetry, one diver visualizes a 5m x 5m corridor alongside each side of the<br />
transect and estimates the size and abundance of all fish, noting also turtles, sea lions, penguins<br />
and cormorants — even the occasional giant manta ray or dolphin. The second diver counts and<br />
measures sizes of all mobile macro‐invertebrates in a 1m band either side of the transect — sea<br />
cucumbers, sea stars, lobsters, oc<strong>to</strong>pus, sea urchins, nudibranchs and large marine snails. The<br />
third diver has perhaps the most challenging task — laying quadrants every 5m along the 50m<br />
transect they catalogue every sessile algae or animal under an 81 intersection grid — that’s<br />
1620 measurements per sampled site across the two depths. They record everything that grows<br />
upon the seafloor — corals, algae, sponges, tunicates, hydroids — usually hugely diverse and in<br />
general quite difficult <strong>to</strong> identify. Over recent years the list of new species has gone up as we<br />
have improved our base line taxonomy. Today we’re routinely covering over 1000 species of<br />
the 2800 registered <strong>to</strong> date in the marine reserve and the list keeps growing.<br />
Subtidal community moni<strong>to</strong>ring<br />
Since 1994, Charles Darwin Foundation divers have moni<strong>to</strong>red over 2000 x 50m transects —<br />
that’s equivalent <strong>to</strong> 3‐4 divers swimming over 100 km, sampling sub‐tidal communities. It<br />
sounds a lot, but still compared <strong>to</strong> the 1670 km of coastline, it is still less than 5% of the <strong>to</strong>tal<br />
reserve. Of course on <strong>to</strong>p of that there is also pelagic moni<strong>to</strong>ring — diver drift dives for large<br />
fish and sharks that live in open water, regular moni<strong>to</strong>ring of coral plots, habitat mapping,<br />
oceanographic work with Conductivity Temperature Density (CTD) profiles, satellite sensor<br />
46
ground truth measurements, plank<strong>to</strong>n net trawls, recruitment traps for fish and lobster,<br />
experimental work with settlement plates, directed searches for threatened species, species<br />
level work <strong>to</strong> study foraging behaviors of higher vertebrates such as penguins, cormorants sea<br />
lions and fur seals, impact assessments for installation of low impact moorings, surveys of hull<br />
growth for invasive marine species, tagging for site fidelity of sharks, deep water explora<strong>to</strong>ry<br />
work with remotely guided submarines, fisheries population moni<strong>to</strong>ring with the National Park<br />
Service…. All run on a shoestring.<br />
So as this trip draws <strong>to</strong> a close, we can say that for 2009 we again have our finger on the pulse<br />
of the marine reserve — information that will be processed and passed on<strong>to</strong> decision makers.<br />
There is a lot of work still <strong>to</strong> do — particularly with making sure that the information gathered<br />
is used in the elaboration of a new management plan for the marine reserve with the National<br />
Park.<br />

Mariana Vera in the field<br />
My name is Mariana Vera, and I’ve been involved in conservation for more than 7 years. Right<br />
now I am working as an associate researcher in the marine coastal research area of the Charles<br />
Darwin Foundation in <strong>Galapagos</strong> (Ecuador). As a science diver, my work is centered around<br />
47
ecological moni<strong>to</strong>ring and I specialize in taxonomic identification of sessile species (such as<br />
corals, tunicates, gorgonians, sponges and algae among others). I have had the opportunity <strong>to</strong><br />
be involved and participate in various science projects that work <strong>to</strong> improve our understanding<br />
of the islands. Some of the work that I do includes:<br />
Participant in research and moni<strong>to</strong>ring trips as a part of the Marine Ecosystem team working as<br />
a scientific diver. (9 Sub‐tidal Eco‐moni<strong>to</strong>ring trips, 3 Oceanographic trips (NASA‐OCEAN), 3<br />

Before working at the research station, I was a consultant for Conservation International,<br />
developing fisheries databases for <strong>Galapagos</strong>, giving interviews <strong>to</strong> the fishing sec<strong>to</strong>r as part of a<br />
CI initiative <strong>to</strong>wards changing fishermen livelihoods (reducing overfishing) and also collected<br />
information from the different sec<strong>to</strong>r groups using the port zones <strong>to</strong>wards implementing a<br />
micro‐zoning <strong>to</strong> coordinate activities in those areas.<br />
I also had the opportunity <strong>to</strong> work in the fisheries moni<strong>to</strong>ring program as a research assistant,<br />
moni<strong>to</strong>ring the main fisheries in the islands (sea cucumbers, lobsters, white fin fish), working<br />
directly with the fishermen down at the local docks, as an on‐board fisheries observer and in<br />
48
the distribution centers. As well as working with the Charles Darwin Research Station, I also<br />
volunteered with their counterpart in the marine resources area of the <strong>Galapagos</strong> National Park<br />
Service.<br />
All that I have experienced since living here, has made me aware of the fragility of these islands<br />
and the serious problems that they confront, not only for marine conservation, but also in the<br />
terrestrial realm. I’m very conscious of the fact that all of us who work in conservation do so<br />
because we have an enormous responsibility and connection <strong>to</strong> preserve these fantastic<br />
islands. For that reason we are willing <strong>to</strong> help, and the only way <strong>to</strong> do that is <strong>to</strong> have a better<br />
understanding of the biodiversity and all and every component of the island ecosystem — that<br />
is the work that drives me and the central mission of the Charles Darwin Foundation.<br />

centros de distribución. También trabaje de voluntaria en la misma área y en el Parque Nacional<br />
Galápagos, en el Área de Recursos Marinos.<br />
Todas las experiencias obtenidas mientras he vivido aquí, me han brindado la posibilidad para<br />
darme cuenta de la fragilidad de estas islas y de los serios problemas que confronta, no solo en<br />
la parte en la parte de conservación marina sino también en la terrestre, soy consciente que<br />
para <strong>to</strong>dos nosotros quienes trabajamos en conservación lo hacemos por que tenemos un<br />
enorme compromiso con estas fantásticas islas y con la conservación de las mismas, por esa<br />
razón estamos dispues<strong>to</strong>s a ayudar a preservarlas, la única manera es teniendo un mejor<br />
entendimien<strong>to</strong> de su biodiversidad y de <strong>to</strong>dos y cada unos de los componentes de sus<br />
ecosistemas, ese es justamente el trabajo que me impulsa y la función central de la Fundación<br />

Angela M. Kuhn<br />
Cuando decidí estudiar oceanografía quizá no imaginé realmente lo que implicaba. Deseaba<br />
una carrera que se relacionara con el ambiente y la comprensión física de sus procesos, que no<br />
sólo me proveyera de un título sino y la sensación de estar haciendo algo por el res<strong>to</strong> del<br />
mundo, que me permitiera disfrutar momen<strong>to</strong>s de tranquilidad en la playa. Ninguna de estas<br />
razones tenía mucho sentido para mis padres. Pero el camino ha de mostrado hasta ahora, con<br />
sus al<strong>to</strong>s y bajos, ser ciertamente gratificante.<br />
Oceanografía es una carrera poco común en Ecuador, muchos ignoran incluso que es impartida<br />
en el país. Desde disección de copépodos y análisis granulométricos, hasta medición de<br />
corrientes y perfiles de playa es como una rápida excursión turística. Así, la primera vez que<br />
llegué a Galápagos fue como pasante en la división de meteorología del crucero oceanográfico<br />
regional de la armada ecua<strong>to</strong>riana, durante mi segunda año de carrera. Fueron sólo un par de<br />
días en tierra, pero el deseo de volver permaneció hasta el final de la misma.<br />
Actualmente, con una beca proporcionada por la Fundación Charles Darwin, realizo mi tesis<br />
sobre la incidencia de la temperatura del mar en las comunidades submareales. Este estudio<br />
sólo es posible gracias al trabajo de muchos investigadores, voluntarios y estudiantes que a lo<br />
largo de más de diez años y como parte de diversos proyec<strong>to</strong>s, han contribuido a la recopilación<br />
y construcción de una base de da<strong>to</strong>s biológicos y oceanográficos de la reserva marina. Pues<strong>to</strong><br />
51
que el área de la reserva de Galápagos está dentro de un sistema físico altamente dinámico, la<br />
variabilidad espacial y temporal es reflejada por igual en la distribución de las comunidades<br />
marinas. Fuertes contrastes en la composición biótica son apreciables incluso en pequeñas<br />
islas, hábitat de algas bajo la influencia de aguas frías de afloramien<strong>to</strong> y parches de coral en<br />
aguas más temperadas, en sitios apenas separados por pocos kilómetros.<br />
Punta Espinoza ‐ 20m<br />
La medida en que las especies responden a variaciones de temperatura da una idea de su<br />
vulnerabilidad a even<strong>to</strong>s de mayor intensidad como El Niño o aumen<strong>to</strong>s progresivos de la<br />
temperatura oceánica, identificando posibles especies indicadoras de los cambios ambientales<br />
por su sensibilidad o adaptabilidad. Muestra además los sitios de la reserva con mayor facilidad<br />
de recuperación y aquellos donde la resilencia debe ser fortalecida. El estudio incluye control<br />
de calidad de series de tiempo de sensores de temperatura a diferentes profundidades, y la<br />
revisión de las relaciones espaciales y temporales es distintas escalas de variabilidad; y observa<br />
el efec<strong>to</strong> del “choque térmico”, o la rapidez en que ocurren los cambios de temperatura.<br />
52
Collecting samples and data<br />
El objetivo conjun<strong>to</strong> y a largo plazo de estudios como este, es la evaluación de la zonificación<br />
costera de la reserva. Reconociendo los sitios de importancia ecológica y aquellos donde la<br />
resilencia natural se encuentra afectada, puede proponerse una redistribución de la presión<br />
antropogénica que permita la sostenibilidad de los recursos.<br />
La beca de la FCD no es tan sólo una facilidad para cumplir un requisi<strong>to</strong> académico. El<br />
asesoramien<strong>to</strong>, apoyo y motivación del equipo de investigación crean un ambiente de<br />
confianza para el desarrollo profesional en esta primera etapa. Permite compartir<br />
provechosamente las capacidades en las distintas áreas de interés específico de cada<br />
investigador y abre un amplio horizonte de visión científica al establecer contac<strong>to</strong> con otros<br />
exper<strong>to</strong>s del ámbi<strong>to</strong>. Charlas, talleres y conversaciones personales con reconocidos científicos<br />
cuyos trabajos han sido parte de mis lecturas como estudiante, contribuyen a una formación<br />
más realística y son continua fuente de inspiración.<br />
Discussing data<br />
Ha sido también la oportunidad de involucrarme con el trabajo base del departamen<strong>to</strong> de<br />
investigación marina. Este incluye la realización de cruceros de moni<strong>to</strong>reo submareal y<br />
oceanográfico para mantener actualizada la base de da<strong>to</strong>s. La temperatura del mar es medida<br />
en sitios establecidos para moni<strong>to</strong>reo, en perfiles hasta 80 metros de profundidad mediante el<br />
uso de un CTD y se <strong>to</strong>man muestras de fi<strong>to</strong> y zooplanc<strong>to</strong>n para análisis posterior en el<br />
labora<strong>to</strong>rio.<br />

gran importancia.<br />
Analyzing, researching<br />
Creo que este “alimen<strong>to</strong>” multidisciplinario es el que a futuro me permitirá una visión más<br />
holística, no sólo del funcionamien<strong>to</strong> del ecosistema y sus interacciones físicas y biológicas, sino<br />
también del necesario rol de cada una de las actividades de investigación. Cada vez <strong>to</strong>do es<br />
nuevo e inquietante, y muchas veces parece difícil elegir qué camino de investigación <strong>to</strong>mar.<br />
Pero ciertamente me hallo fascinada por la noción del movimien<strong>to</strong>. Nuestro universo entero,<br />
nuestro planeta se mueve en ciclos de armonía. Así como el vien<strong>to</strong> provoca las ondulaciones del<br />
55
mar, y ondas internas dentro de él propagan cambios que bosquejan las condiciones para el<br />
establecimien<strong>to</strong> de distin<strong>to</strong>s hábitats y comunidades; los hombres deberíamos movernos por<br />
igual en conjun<strong>to</strong> con nuestras necesidades y las capacidades de nuestro ambiente. Y el papel<br />
de la ciencia es tratar de explicar es<strong>to</strong>s ciclos para re‐educarnos en el cómo.<br />
Sunset<br />
La aplicación de los conocimien<strong>to</strong>s científicos para una eficaz respuesta que favorezca a la<br />
conservación y susten<strong>to</strong> de las poblaciones costeras ecua<strong>to</strong>rianas, es el fin que presenta para<br />
mí el mayor atractivo. Así, espero continuar mi carrera en ámbi<strong>to</strong>s de ecología aplicada y<br />
manejo ambiental costero que permita la construcción de índices de fácil entendimien<strong>to</strong> y<br />
utilización en medidas y políticas.<br />

Rober<strong>to</strong> Pépolas<br />
My main role within the Charles Darwin Foundation is <strong>to</strong> be aware of the safety during the field<br />
activities in the marine and terrestrial areas. I also participate in the different marine research<br />
projects that are going on. In the ecological Moni<strong>to</strong>ring after seven years of participation; I<br />
identify and take notes of the number and size of the fishes inside the transects we run across<br />
the entire Marine Reserve of this wonderful and unique paradise.<br />
Another fundamental part of my duties is <strong>to</strong> ensure that all the equipment regarding the diving<br />
operation are in optimal conditions (scuba equipments, compressors, inflatable boats,<br />
outboard engines, etc).<br />
59
Checking equipment, hanging out, diving<br />
There are other interesting and important projects running in the Marine area where I’m also<br />
involved, such as the <strong>Galapagos</strong> and Hammerhead’s shark tagging and/or the installation of<br />
permanent anchors (Halas and Helix systems) where I lead the practical component.<br />
I definitely must admit that I consider myself a lucky person and thankful <strong>to</strong> have a life which<br />
gives me the possibility <strong>to</strong> know the amazing and beautiful underwater world of the <strong>Galapagos</strong><br />
islands, <strong>to</strong> be able <strong>to</strong> contribute a little <strong>to</strong>wards conserving it and <strong>to</strong> allow me <strong>to</strong> have a family<br />
where I can see my kids growing up surrounded by peace and nature.<br />

We have at the moment the necessary basic <strong>to</strong>ols <strong>to</strong> be able <strong>to</strong> perform our objectives; but it<br />
would be ideal if we could get in the near future new technology that is already available but<br />
we are not able <strong>to</strong> possess because of the lack of economical resources, such as: Enriched Air<br />
Nitrox , rebreathers and dry suits. Counting upon such equipment would contribute <strong>to</strong> reduce<br />
60
the risks regarding diving illness and also <strong>to</strong> get more and/or different scientific types of<br />

lo que a su instalación práctica se refiere.<br />
Cabe mencionar que Julio Delgado, nacido en la isla San Cristóbal y Divemaster, quien trabaja a<br />

Definitivamente, debo admitir , que me considero una persona muy afortunada y agradecida<br />
con la vida , por haberme dado la posibilidad de conocer el increíblemente bello mundo<br />
submarino que Galápagos posee , de poder contribuir un poqui<strong>to</strong> en conservarlo y de haber<br />
formado una familia y ver crecer a mis hijos rodeados de tanta paz y naturaleza.<br />
Contamos al momen<strong>to</strong> con las herramientas básicas necesarias para poder cumplir con<br />
nuestros objetivos, pero seria ideal a futuro, poder contar con mayor tecnología que al<br />
momen<strong>to</strong> es accesible pero la cual no poseemos debido a la escasez de recursos económicos<br />
como por ejemplo: Aire enriquecido (EAN), Equipos de circui<strong>to</strong> cerrado y trajes de buceo secos.<br />
El poder contar con lo antes mencionado, contribuiría enormemente en cuan<strong>to</strong> a poder reducir<br />
riesgos de enfermedades relacionadas al buceo y a su vez en la obtención de mayor<br />

Edi<strong>to</strong>r’s note: A second Spanish‐only guest blog, from Gene’s shipmate Nathalia Tirado Sánchez,<br />
describes how a family vacation <strong>to</strong> the tropics when she was five ended up with them staying <strong>to</strong><br />
live on the <strong>Galapagos</strong>. At that age, she remembers feeling like she had gone back in time, <strong>to</strong> a<br />
place where dinosaurs (marine iguanas) still lived. Volunteer work with the Charles Darwin<br />
Foundation fostered a strong desire <strong>to</strong> do work that was connected <strong>to</strong> the ocean life of the<br />
islands. Today, she is studying the relationship between ocean conditions and the zooplank<strong>to</strong>n<br />
of the <strong>Galapagos</strong>. At the end of her post, she talks about how important it is <strong>to</strong> her <strong>to</strong> teach her<br />
children and the rest of their generation about the unique ecology of the <strong>Galapagos</strong> so that<br />
those who love the islands and want <strong>to</strong> live there have the information they need <strong>to</strong> preserve<br />
the place they love for future generations.<br />

Realmente aún no es<strong>to</strong>y segura del momen<strong>to</strong> en que mi familia emprendió unas vacaciones de<br />
verano de la sierra ecua<strong>to</strong>riana y terminamos quedándonos a vivir en las Islas Galápagos, nos<br />
encantó un lugar misterioso, tranquilo y alejado de la vida de ciudad; con un espectáculo único,<br />
que jamás habíamos vis<strong>to</strong>, hasta ahora recuerdo mi primera impresión de niña a los 5 años fue<br />
que llegue al pasado, cuando aún existían dinosaurios (iguanas marinas), pero nada que ver<br />
65
es<strong>to</strong>s eran muy pequeños. Desde en<strong>to</strong>nces no he dejando de aprender cada día sobre éste<br />
hermoso rincón que ahora es herencia natural de la humanidad.<br />
Iguanas<br />
A medida que pasaba el tiempo fue aprendiendo a vivir de forma y con necesidades diferentes<br />
a las de una ciudad, ejemplo nunca de niña nunca tuve un programa de televisión favori<strong>to</strong>,<br />
tenia rincón de snorkel favori<strong>to</strong>, ese tipo de cosas que no se hacen con facilidad en una ciudad.<br />
En fin quería conocer mas sobre la diversidad de Galápagos y quise ser voluntaria de la<br />
Fundación Chales Darwin, inicialmente en asun<strong>to</strong>s contables pero no era suficiente, buscaba<br />
algo más que me permitiera sentirme parte del lugar en que vivía y que a la vez me hiciera feliz,<br />
una combinación poco fácil de conseguir pero creo que había descubier<strong>to</strong> el camino.<br />
Finalmente me encontré nuevamente viviendo en la ciudad y tratando de acomodar mi vida<br />
provinciana a citadina, es así que terminé estudiando una carrera en Ciencias, pensaba que<br />
sería muy fácil, descubrir cosas nuevas y aportar cada día con mis conocimien<strong>to</strong>s a mejorar la<br />
conservación de la biodiversidad de Galápagos.<br />
Inicialmente trabaje en asun<strong>to</strong>s pesqueros y <strong>to</strong>do lo relacionado con el sistema de moni<strong>to</strong>reo<br />
primero de recursos como canchalagua (Qui<strong>to</strong>n), luego con moni<strong>to</strong>reo de especies de interés<br />
comercial como langostas y pepinos de mar. Durante mi tiempo de vacaciones y tiempo<br />
haciendo voluntariados en la Fundación Charles Darwin, logre descubrir que llegaban a mí el<br />
interés en los organismos más microscópicos que son la fuente principal de vida en el mar. Una<br />
vez terminada mi carrera inicié el estudio de zooplanc<strong>to</strong>n en la isla Santa Cruz, y que<br />
posteriormente se extendió a <strong>to</strong>da la Reserva Marina de Galápagos (RMG) con la finalidad de<br />
caracterizar la variabilidad del zooplanc<strong>to</strong>n para la RMG y su relación con fac<strong>to</strong>res<br />
oceanográficos; fácilmente conceptualizado, luego de un par de años en el microscopio ahora<br />
tengo un amplio juego de da<strong>to</strong>s para empezar a procesar las relaciones conceptualizadas.<br />
66
Water sample<br />
Finalmente con la información recaba durante el análisis de labora<strong>to</strong>rio he completado una<br />
Base de da<strong>to</strong>s de las especies de zooplanc<strong>to</strong>n registradas para la RMG en cada sitio muestreado<br />
en la RMG con información ecológica de las especies y una pequeña guía fo<strong>to</strong>gráfica de algunas<br />
de las especies identificadas. Actualmente se encuentra disponible en la página web de la FCD,<br />
y que esperamos incrementar con el transcurso del tiempo y la red de colaboradores que<br />
actualmente se está desarrollado con esta finalidad.<br />
Ya a bordo de una embarcación era casi imposible vencer la tentación de empezar a explorar el<br />
mundo submarino, y finalmente me decidí obtuve mi certificación de buceo y empecé a<br />
explorar el fondo marino, nada más maravilloso que cien<strong>to</strong> de peces nadando jun<strong>to</strong> a ti, cual<br />
peces nuevo que <strong>to</strong>dos quieren conocer o los inquie<strong>to</strong>s lobi<strong>to</strong>s marinos que a decir por los<br />
comentarios de una compañero cuando son jóvenes su al<strong>to</strong> grado de actividad pueden<br />
dificultar enormemente el trabajo submarino. Y por supues<strong>to</strong> ahora ayudo en el trabajo de<br />
campo colectando información de organismos macroinvertebrados móviles (langostas, erizos<br />
de mar, pepinos, gasterópodos grandes) lo que me ha permitido conocer a Galápagos no solo<br />
en sus ambientes terrestres sino también submareales, lo que me ha permitido tener una<br />
mejor idea de lo diverso y maravilloso de este pequeño pun<strong>to</strong> geográfico en el mundo.<br />
67
Nathalia<br />
Entre idas y venidas entre la universidad y Galápagos conocí a la persona con la que compar<strong>to</strong><br />
mis días, y tuvimos un hijo hermoso que de algún modo reafirmó mis raíces en el lugar que<br />
amo, luego mi hija los dos de la misma edad, que han desarrollado en mi las ganas de querer<br />
ser parte de la solución y crear cosas que ayuden a cambiar la forma de vida de la gente que<br />
habita en las Islas Galápagos, que a mi criterio es una de los problemas de enfrenta<br />
actualmente la región.<br />
Nathalia<br />
Por lo que pienso que uno de los principalmente temas que necesitan ser fortalecidos en el<br />
educativo, me he vincula a la escuela de mis hijos queriendo fortalecer las capacidad de la<br />
institución y a la vez quiero ayudar a formar una nueva generación de seres humanos que<br />
realmente tengan muy clara la particularidad de las islas Galápagos y que hayan desarrollado<br />
68
un al<strong>to</strong> grado de sensibilidad con el medio que los rodea, conocedores de aspec<strong>to</strong>s físicos,<br />
químicos‐ biológicos y humanos de medio y sus interacciones y sus problemas actuales y<br />
futuros, no solo el concep<strong>to</strong> de un lugar de ensueño que actualmente con la creciente empresa<br />
turística crece ampliamente. Creo que el mejor modo de entender y conocer las cosas es a<br />
través de vivir día a día consientes de cada una de nuestras actividades diarias y a la vez<br />
mejorando el aspec<strong>to</strong> ambiental que está incorporando lentamente en el currículo formal del<br />
perfil de los niños y jóvenes que han nacido y quieres vivir el res<strong>to</strong> de su vida en las islas. De tal<br />
modo que conjuntamente con otros maestros con el mismo criterio hemos tratado de<br />
implementar actividades que nos permitan conocer y valorar lo que tenemos, y sobre <strong>to</strong>do una<br />
consciencia real de cual es el rol de cada uno en el lugar que hemos decidido vivir y que<br />
queremos conservar para el mañana.<br />
“Vive el lugar que amas” Patricio Proaño.<br />
Creo firmemente que el mejor modo de conservar, preservar o cualquier término que<br />
busquemos para lograr este fin, es a través de crear una cultura de vida propia de la gente de<br />
este lugar, muy alejada a la de una ciudad, pero única debido a valor biológico, histórico y<br />
cultural que representa Galápagos para el mundo.<br />

Be Careful What You Wish For<br />
SeaWiFS<br />
Ever since SeaWiFS was launched back in August of 1997, I had hoped <strong>to</strong> figure out some way of<br />
getting a high resolution satellite receiving station installed on the islands <strong>to</strong> collect a time<br />
series that would once and for all provide a data set for generations <strong>to</strong> come that would help<br />
characterize the ocean’s biological response <strong>to</strong> a changing environment in this most unique<br />
part of the world. Unfortunately, things never seemed <strong>to</strong> work out quite right until a cold<br />
November day in 2000 when I first met Stuart Banks. After a number of e‐mail exchanges with<br />
some folks in <strong>Galapagos</strong> and Stuart, his travel plans were changed at the last minute so that he<br />
s<strong>to</strong>pped off at Goddard on his way down <strong>to</strong> the <strong>Galapagos</strong> for the second time and spent the<br />
evening at my home and the next day at Goddard where <strong>to</strong>gether with John Morrison, we<br />
hatched a plan that was <strong>to</strong> profoundly influence the course of both of our lives. To this day,<br />
both my daughters who were 17 and 12 at the time remember the night they had dinner with<br />
this very charming young man from Great Britain with the terrific accent. For me, it was<br />
realization of a dream that started back in 1982 when I first started observing these marvelous<br />
islands from space with data from the Coastal Zone Color Scanner. For Stuart, it was the start<br />
of what was <strong>to</strong> become an incredible scientific and personal adventure that continues <strong>to</strong> this<br />
day.<br />
I asked Stuart <strong>to</strong> try and find some time in between the continuous diving and data logging that<br />
has filled his team’s days onboard the M/V Queen Mabel <strong>to</strong> provide a more personal<br />
perspective on his work here in <strong>Galapagos</strong>. True <strong>to</strong> form, Stuart went way beyond what I could<br />
have ever hoped for and here is what he wrote.<br />

When asked whether I’d like <strong>to</strong> contribute <strong>to</strong> a blog about my time in <strong>Galapagos</strong> I wasn’t<br />
entirely sure where <strong>to</strong> start. It’s fair <strong>to</strong> say that even now after eight years of often unbelievable<br />
(occasionally surreal) moments, chain of unlikely events, a fair share of challenges (<strong>to</strong> put it<br />
mildly) it is still something of a surprise that I find myself here, rolling around in a boat with the<br />
smoldering volcano of Fernandina Island looming over the mist out the window as I try <strong>to</strong><br />
71
punch fish data in<strong>to</strong> my lap<strong>to</strong>p. Time and time again I find it helps <strong>to</strong> have a little reality check<br />
<strong>to</strong> remind yourself where you are — just in case you get used <strong>to</strong> it…<br />
Stuart, scenes from the <strong>Galapagos</strong><br />
Ten years ago I caught my first glimpse of <strong>Galapagos</strong>, but from afar. By afar, I should say,<br />
satellite images. Studying oceanography in the National Oceanography Centre in the south of<br />
England, I began <strong>to</strong> look at how sea surface temperature changed around the archipelago using<br />
satellite data, yet never could have guessed how close it would finally take me <strong>to</strong> the islands. In<br />
2000 I was asked <strong>to</strong> help organize the first marine biodiversity records at the Charles Darwin<br />
Research Station (CDRS) — a step that <strong>to</strong>ok me on a roundabout route through NASA‐GSFC, and<br />
led <strong>to</strong> the installation of a dedicated receiving station for the SeaWiFS mission collecting data<br />
across the Eastern Tropical Pacific.<br />
Installation of the SeaWiFS receiving station<br />

Computer interface for the receiving station<br />
A fair amount of “Spanglish” and a multitude of research projects have since taken us across<br />
the entire <strong>Galapagos</strong> Marine Reserve — some of the first descriptions of the marine realm since<br />
being declared a World Heritage site, thanks <strong>to</strong> a cast of dozens of marine scientists.<br />
I was captivated by the challenge and great unknowns that remain in <strong>Galapagos</strong>, changing hats<br />
as oceanographer, marine biologist, ecologist, GIS technician, science diver, developing marine<br />
projects for the Charles Darwin Foundation with a colorful cast of characters — fishermen, <strong>to</strong>ur<br />
opera<strong>to</strong>rs, international scientists, conservation Non Governmental Organizations (NGO), navy<br />
researchers, and Park rangers. The niche that first attracted me was the determination of<br />
oceanographic processes — the driving forces behind marine biodiversity and biogeography in<br />
the <strong>Galapagos</strong> Marine Reserve (GMR) at the small scales important <strong>to</strong> management. To that<br />
end we’ve helped coordinate research in a number of complementary projects (NASA satellite<br />
oceanography, marine ecosystem dynamics, long term <strong>Galapagos</strong> moni<strong>to</strong>ring systems<br />
evaluating Marine Protected Area (MPA) effectiveness, coral surveys, IUCN red listing, search<br />
for rare species, climate change adaptation etc.) that use a range of methods <strong>to</strong> examine<br />
human and climatic interactions in the coastal zone. National Park partners, Navy, local<br />
organizations and visiting scientist groups, are all vital collabora<strong>to</strong>rs. It’s the technical<br />
information that we develop <strong>to</strong>gether engendering a sense of ownership that helps evaluate<br />
and improve adaptive management measures as the islands and community continually<br />
change. “Climate smart” marine protected areas, invasive species control, long term<br />
biodiversity conservation and sustainable fisheries and <strong>to</strong>urism management are easy <strong>to</strong> write<br />
down on a proposal, but less straightforward <strong>to</strong> put in<strong>to</strong> practice.<br />
Strangely enough <strong>Galapagos</strong> presents two faces for me — which are difficult <strong>to</strong> reconcile. The<br />
side of <strong>Galapagos</strong> that never fails <strong>to</strong> amaze and inspire will be apparent <strong>to</strong> anyone fortunate<br />
enough <strong>to</strong> have dipped their head below the waterline in the archipelago.<br />
73

We are usually blown away not by crystal clear water (far from it), but by the as<strong>to</strong>unding<br />
charismatic life and variety. In fact it’s the pea soup of productivity (the same that the SeaWiFS<br />
sensor so dramatically highlighted) that brings life <strong>to</strong> the islands — from schools of hundreds of<br />
hammerhead sharks, <strong>to</strong> immense mantas, penguins darting like feathered <strong>to</strong>rpedos through<br />
cold upwelled water, <strong>to</strong> orcas and whale sharks, endemic scallops peering at you through<br />
dozens of eyes while spotted morays peer between massive coral heads, sealions tug at your<br />
fins and whales breach alongside sheltered bays.<br />
You realize very quickly, that this is a place worth fighting for. Some of my most memorable<br />
moments are beneath the water — being eye <strong>to</strong> eye with a 60ft humpback and screaming non<br />
s<strong>to</strong>p for 5 minutes is up there as being fairly unforgettable, as well as watching huge ungainly<br />
Mola mola sunfish cruise past as flightless cormorants glide around searching for a damsel fish<br />
snack.<br />
The other face is more worrying. Over the last 40 years the human presence in the islands has<br />
increased exponentially, and we are rapidly reaching a critical crossroads between a sustainable<br />
future for the islands, or a shift in the natural environment where we stand <strong>to</strong> lose biodiversity.<br />
<strong>Galapagos</strong> is no stranger <strong>to</strong> change — since pirates arrived in previous centuries and whalers<br />
removed huge numbers of <strong>Galapagos</strong> giant <strong>to</strong>r<strong>to</strong>ises as fresh food s<strong>to</strong>res on ships, there has<br />
been a human footprint. Today res<strong>to</strong>ration programs between Charles Darwin Foundation and<br />
the Park have greatly res<strong>to</strong>red these populations — although Lonesome George, last of his kind<br />
74
holds testimony <strong>to</strong> how susceptible endemic species are <strong>to</strong> extinction upon such small islands.<br />
A repeating pattern of overexploited coastal fisheries for sea cucumber and lobster, fishing<br />
down the food web for coastal fin fish, and <strong>to</strong>day a huge increase in <strong>to</strong>urism (one of the most<br />
rapid in the world) creates a new set of challenges for conservation.<br />
Human impact on climate change<br />
Marine accidents and oil spills occur more frequently, overfishing and illegal fishing of keys<strong>to</strong>ne<br />
reef preda<strong>to</strong>rs such as reef fish and lobster and shark encourages the formation of uncontrolled<br />
urchin barrens, reducing the capability of the marine ecosystem <strong>to</strong> recover after strong El Niño<br />
events. As <strong>to</strong>urism drives development, more materials and flights increase the chances that<br />
invasive species establish in the islands. At huge expense goats, rats, cats, pigs have been<br />
eradicated from some islands, wild blackberry persists as do fire ants. The microscopic threats<br />
are less easy <strong>to</strong> remove — avian flu, West Nile virus in the islands would be catastrophic.<br />
Overlaid upon everything is the ever present El Nino Southern Oscillation (ENSO) — with global<br />
climate change we expect that these climatic events will certainly be more intense. As climate<br />
shifts, the biophysical gradients shift with implications for the entire ecosystem and the<br />
resources upon which the local community depends.<br />
In fact those are a few of the reasons why we’re here this week freezing under the sea while<br />
under the equa<strong>to</strong>rial sun. Rolling around in the swell and peering through a pea soup of<br />
plank<strong>to</strong>n upwelling around the western islands. It’s part of a long term submarine and coastal<br />
moni<strong>to</strong>ring program <strong>to</strong> both understand the interaction between climate, oceanography,<br />
marine communities, human use and also help evaluate and improve management measures<br />
such as the <strong>Galapagos</strong> Marine Reserve (GMR) coastal zoning system of fisheries take and notake<br />
<strong>to</strong>urism and Marine Protected Areas.<br />
75
The Charles Darwin Foundation is an international NGO that works as technical advisory <strong>to</strong> the<br />
Ecuadorian government applying that science <strong>to</strong> the conservation of the <strong>Galapagos</strong> <strong>to</strong> help get<br />
a handle on these problems and plan for a sustainable future. Although much of the solution<br />
lies in supporting governance, it is vitally important <strong>to</strong> have your finger on the “pulse” of the<br />
reserve. The trick is how <strong>to</strong> make the links between people and key messages and also<br />
understand the interdependencies between the needs of GMR users and the capacity of the<br />
natural resource <strong>to</strong> support their activities without degrading the natural function of the unique<br />
ecosystem.<br />
So as we work <strong>to</strong> understand and protect the <strong>Galapagos</strong> Marine ecosystem, how it changes its<br />
unique character between seasons, between years under the El Nino Southern Oscillation and<br />
under the drastic changes since people colonized the islands, it’s comforting <strong>to</strong> know that there<br />
are some extremely talented people here on the islands doing the best they can under difficult<br />
circumstances <strong>to</strong> draw attention <strong>to</strong> the problems and search for solutions. The key is how <strong>to</strong><br />
reduce those novel human stresses so that the “human footprint” becomes as light as possible.<br />
An international network of those inspired by ambling iguanas and dramatic lunar landscapes<br />
watching <strong>Galapagos</strong> from afar — through their universities, through interested concerned<br />
individuals… even from space – all have helped a huge amount. But I most admire those local<br />
researchers and Park rangers dedicating themselves day <strong>to</strong> day – not the least of whom are on<br />
this same boat working <strong>to</strong> put the pieces <strong>to</strong>gether for a sustainable future for the Islands.<br />

It will always be a privilege <strong>to</strong> be here and work with them on what often seems a frontier<br />
between development and conservation values. If we can do it in a place like <strong>Galapagos</strong>, then<br />
there’s some hope for the rest of the world’s oceans.<br />

Diving in Ash<br />
Thinking back on all of the things that have led up <strong>to</strong> my Journey <strong>to</strong> <strong>Galapagos</strong>, I would have<br />
never realized the impact that a simple one line e‐mail would have. It all started with this note<br />
that I sent <strong>to</strong> Stuart Banks on the morning of 13 April 2009:<br />
To: Stuart Banks<br />

Hi Gene,<br />
Eruption in Fernandina Island – lava reached the coast in just 1 day<br />
(SW Cabo Hammond), so seems like a big one!<br />
Stuart<br />
Little could I imagine that in a little more three months time, I would be at that very spot sitting<br />
in a zodiac as Stuart and the dive team from the Charles Darwin Research Station went over the<br />
side and beneath in<strong>to</strong> the depths in hopes of gazing at some of the newest land on Planet<br />
Earth.<br />

Eruption on Isla Fernandina<br />
In early April 2009, La Cumbre Volcano on Isla Fernandina in the <strong>Galapagos</strong> Islands erupted.<br />
Sulfur Dioxide Plume from Isla Fernandina<br />
A combination of two satellite overpasses tracks the movement of sulfur dioxide westward<br />
from Isla Fernandina on April 14, 2009.<br />
78
Eruption on Isla Fernandina, April 14, 2009<br />
La Cumbre Volcano on Isla Fernandina continued erupting in mid‐April 2009. On April 14, 2009,<br />
continuous ash and steam emissions produced a plume that stretched some 250 kilometers<br />
(135 nautical miles) west of the summit, according <strong>to</strong> the U.S. Air Force Weather Agency.<br />
I have <strong>to</strong> say that although I had become very familiar with those images of the eruption, they<br />
certainly did not prepare me for what it felt like <strong>to</strong> be actually steaming back and forth along<br />
that primordial coastline, a place whose description I have found none better than that written<br />
in 1835 by FitzRoy in his Journal of the Voyage of the Beagle:<br />
“we then weighed [anchor], and continued our examination of this unearthly shore. Passing a<br />
low projecting point, our eyes and imagination were engrossed by the strange wildness of the<br />
view; for in such a place Vulcan might have worked. Amidst the most confusedly heaped masses<br />
of lava, black and barren, as if hardly yet cooled, innumerable craters (or fumeroles) showed<br />
their very regular, even artificial looking heaps. It was like immense iron works, on a Cyclopian<br />
scale!”<br />
Although we had what was the exact location of the place where the lava entered the sea as<br />
provided <strong>to</strong> us by Godfrey Merlen (more on him in a bit), it was hard <strong>to</strong> discern exactly what<br />
might have been the most recent deposit amongst all the charred and jagged rubble that we<br />
could see along the coast. The captain carefully guided the Mabel as close <strong>to</strong> the coast as he<br />
felt it safe <strong>to</strong> go and everyone was perched along the rail trying <strong>to</strong> pick out something that<br />
would indicate the recent lava flow.<br />
Checking out the eruption<br />
However, there was one absolutely unique feature that repeatedly drew our attention as we<br />
passed back in forth in front of it and at first we thought that it might actually be an emerging<br />
flow of fresh lava since the color and texture seemed <strong>to</strong> indicate as much. Curiously, what was<br />
missing was the steam that we assumed must accompany such an event and as much as we<br />
looked, we could not see even a wisp of smoke. Unfortunately, there were no geologists on<br />
board so a more accurate identification of what this actually was will have <strong>to</strong> wait until we hear<br />
back from some of the geologists <strong>to</strong> whom we have passed along the pho<strong>to</strong>graphs of this most<br />
perplexing feature.<br />
79
Molten lava<br />
Using the coordinates that we had been given by Godfrey and our best read of the coastline,<br />
the dive teams decided on the location that they felt was most likely the site of the fresh lava<br />
flow and headed out in the pangas with me tagging along for the ride. Over they went but<br />
unlike previous dives where the teams would remain submerged for more than hour, they<br />
surfaced very soon and I’ll let Stuart fill in the details as <strong>to</strong> why:<br />
“With a large swell crashing against the cliffs a quick check with the handheld depth sounder<br />
showed that the lava more than 2 months before had plunged straight off of the cliff carving it’s<br />
path in<strong>to</strong> deep water – bringing our dive very close <strong>to</strong> the shore. One of the first things we<br />
noticed was a strange milky coloration in the water amid the normal deep blue that spread out<br />
from that point on the coast for more than 200m in each direction. Entering the milky water<br />
caught in the huge swell we headed down, yet could not see more than a meter in any direction.<br />
People vanished from sight within seconds. Just 15ft down the little light piercing the cold water<br />
rapidly disappeared leaving a claustrophobic inky blanket through which we could see nothing,<br />
just relying upon our dive instruments. At 50ft the visibility was a little better — just enough <strong>to</strong><br />
see some large slabs covered in quick recruiting barnacles, a turbid mulch of volcanic ash and<br />
rolling newly formed lava boulders loose in the powerful swell. Disorientated divers returned <strong>to</strong><br />
the surface, rapidly picked up by our zodiacs in the surface surfing the waves. Future months will<br />
tell how the sea reclaims the new lava thrown in<strong>to</strong> the ocean, yet on that morning, the lasting<br />
aftermath of the magma was still very evident.”<br />
80
Diving at the site of the fresh lava flow<br />
The fact that we had the we knew exactly where <strong>to</strong> look was because of a latitude and<br />
longitude that was written on a small sheet of paper and given <strong>to</strong> me by Godfrey Merlen who I<br />
had the pleasure of spending an afternoon with before we set sail on the M/V Queen Mabel.<br />
Godfrey has been in <strong>Galapagos</strong> for nearly forty years and has seen so many changes over that<br />
time and unfortunately, many of them not all that positive. Godfrey believes so strongly in the<br />
uniqueness of <strong>Galapagos</strong> and how crucial it is <strong>to</strong> protect these Islands for future generations<br />
and he is one of those rare people who can articulate in words what he feels in his heart in a<br />
way that not only can anyone understand but that is hard <strong>to</strong> refute.<br />
81
Godfrey Merlen<br />
An online biography of Godfrey gives some of the basics:<br />
He is a permanent resident of <strong>Galapagos</strong> and lives in Puer<strong>to</strong> Ayora on Santa Cruz Island. Mr.<br />
Merlen works closely with the <strong>Galapagos</strong> National Park Service and the Charles Darwin<br />
Research Station of which he is a general assembly member. He has published a number of<br />
articles and several books on the biology and conservation of the islands. Primarily trained in<br />
biology and farming, he has directed his attention <strong>to</strong> the marine environment and conservation<br />
matters. He is also a licensed boat captain and carries out marine mammal research in<br />
Ecuadorian waters.<br />
While speaking with Godfrey I realized that he had so much <strong>to</strong> say that I wanted <strong>to</strong> be able <strong>to</strong><br />
pass along that I asked whether or not it would be alright if I videotaped our conversation.<br />
Thirty minutes later I had a tape of some wonderful s<strong>to</strong>ries about <strong>Galapagos</strong> and thoughts<br />
about its future. I hope <strong>to</strong> be able <strong>to</strong> make that interview available as part of this journal once I<br />
return <strong>to</strong> the States. However, I did ask Godfrey <strong>to</strong> summarize the work that he is currently<br />
involved with and here is what he wrote:<br />
“In essence I am working at present on the reestablishment of the 1000km oceanic barrier that<br />
existed previous <strong>to</strong> mans arrival. Without this barrier the future of the biodiversity of the<br />
82
<strong>Galapagos</strong> archipelago is bleak since the arrival of introduced organisms, including diseases,<br />
plants and animals (especially invertebrates) cause havoc in isolated oceanic islands. The work<br />
involves a hands on approach requiring meetings at high levels of government <strong>to</strong> generate<br />
dedicated support and legal frameworks, and the research and development of known<br />
technologies that can act as modern isolation mechanisms. Through this process the<br />
outstanding biological qualities of <strong>Galapagos</strong> will be preserved and future generations can<br />
experience the enchantment of the islands as we do <strong>to</strong>day.”<br />
Godfrey was also kind enough <strong>to</strong> pass along a pho<strong>to</strong>graph showing him standing on the deck of<br />
his little ship Ratty as the newly erupted lava flowed in<strong>to</strong> the sea just behind him on that day in<br />
April 2009 which clearly explains why he knew exactly where <strong>to</strong> send us. In case you may think<br />
that Ratty is an odd name for a boat or that it refers <strong>to</strong> the condition of Godfrey’s vessel you’d<br />
be wrong on both counts. The name comes from that classic 1909 children’s book by Kenneth<br />
Graham entitled “The Wind in the Willows” which has one of the truest lines ever written,<br />
“There is nothing — absolutely nothing — half so much worth doing as messing about in boats”<br />

Addendum <strong>to</strong> Final CDF-CI <strong>Galapagos</strong>-MMAS Project Report<br />
Attn: John Tschirky<br />
Re: MMAS <strong>Galapagos</strong> <strong>Science</strong> <strong>to</strong> <strong>Action</strong> Component.<br />
Date: 08 th Sept 2010.<br />
Following your recent request, please find here an overview of the <strong>Galapagos</strong> <strong>Science</strong> <strong>to</strong><br />
<strong>Action</strong> (S2A) outreach package financed through the project spending extension <strong>to</strong> June<br />
30 th 2010 and also details of our involvement in additional counterpart activities facilitated<br />
by the MMAS Phase One synthesis beyond the original MMAS project timeframe.<br />
“Business as usual” CDF outreach and technical accessory activities by MMAS funded<br />
investiga<strong>to</strong>rs over the project (within our mandate <strong>to</strong> provide scientific information for<br />
GMR management) involved a range of short courses, presentations and involvement in<br />
workshops and meetings with local students, naturalist guides, <strong>to</strong>urists, park rangers,<br />
ministry representatives, fishermen and <strong>to</strong>urism opera<strong>to</strong>rs. Specific consultations were<br />
varied including participa<strong>to</strong>ry management advisory and technical accessory for the<br />
<strong>Galapagos</strong> National Park Service (GNPS) particularly as part of coastal zoning related task<br />
groups (as part of the GNPS working group) between inhabited Islands and annual revision<br />
of viability for local sea cucumber, fin fish and lobster fisheries.<br />
Specifically the S2A outreach component of our MMAS work with CI-<strong>Galapagos</strong> and<br />
independent contrac<strong>to</strong>r Testugo led <strong>to</strong> a package constructed around CDF and University<br />
San Franscico Qui<strong>to</strong> (USFQ) key science messages developed in the final technical report.<br />
It also involved considerable consultation with our science group who also generated new<br />
additional content. The objectives were (1) <strong>to</strong> deliver key S2A messages, (2) improve the<br />
visibility of scientific accessory <strong>to</strong>wards understanding <strong>Galapagos</strong>, (3) emphasize the role<br />
of science in management and key role of local community members as long term GMR<br />
stewards, (4) improve receptivity of stakeholders <strong>to</strong> sustainability criteria encouraging the<br />
use of such information <strong>to</strong> responsibly conserve their biodiversity resource, support<br />
managers rather than create unproductive confrontation etc. and yet retain or improve local<br />
social capital and (5) create a S2A vehicle and identity for follow up campaigns in the<br />
future.<br />
The final outreach package is being publically launched in September 2010 locally in<br />
<strong>Galapagos</strong> and includes a series of videos and documented interviews with stakeholders<br />
from government representatives, scientists, guides <strong>to</strong> fishermen giving their perspective<br />
concerning the usefulness of science for management, background documentation and<br />
materials designed <strong>to</strong> help facilitate the next steps in management plan reform for the<br />
GMR. The package itself has an interactive DVD designed by Testugo with input from CI<br />
and CDF, a simplified pull out GMR map with important conservation features and is<br />
accompanied by a series of radiospots, a local project slogan and logo <strong>to</strong> help ID the<br />

campaign and coffee mugs with slogans <strong>to</strong> distribute <strong>to</strong> stakeholders. A press conference<br />
will accompany the launch and CDF outreach and communication staff are working with<br />
the CI-Testugo contrac<strong>to</strong>r passing info and launch event invitations <strong>to</strong> the media and<br />
government ministers in Qui<strong>to</strong> and Guayaquil. Follow up informal discussion events are<br />
scheduled <strong>to</strong>wards the end of the year with different user groups leading in<strong>to</strong> structured<br />
workshops for GMR management review in<strong>to</strong> 2011.<br />
The intention is that if successful over the next year, the MMAS outreach component could<br />
develop in<strong>to</strong> a recognized vehicle for applied science recommendations for decision makers<br />
and perhaps more important – attack the MMA stewardship problem from a different angle.<br />
Wider discussions between the science-conservation and local community encourages<br />
consideration of base stakeholder perceptions as part of the problem solving process.<br />
Facilitating and incorporating viewpoints through engaging materials and informal science<br />
discussions improves grass-root appreciation of <strong>Galapagos</strong> sustainability problems, and<br />
also provides a better sense for conservation project managers of alternative visions for the<br />
Islands, possible misconceptions and synergies, consensus perceptions useful in orientating<br />
follow up projects and critical “bottle neck” issues requiring practical solutions if we are <strong>to</strong><br />
approach GMR conservation goals.<br />
At a more conceptual level we hope such steps are catalysts helping long term reform of<br />
the multi-ac<strong>to</strong>r “<strong>Galapagos</strong> conservation conscience”. A complementary approach based<br />
around engaging and empowering a broad base of individuals rather than just politicians,<br />
improves congruence between directed science based recommendations and appropriation<br />
of resulting management measures by GMR user groups. Improved information flow with<br />
feedback from stakeholders before critical management meetings/ decisions can greatly<br />
help <strong>to</strong> validate and reinforce the process, reduce confounding miscommunication, help<br />
ratify new legislation and facilitate more productive negotiations. Ultimately there’s the<br />
hope that appropriation of concepts and conservation measures by individuals will reduce<br />
GMR infractions, increase political aperture <strong>to</strong>wards appropriate distribution of benefits<br />
and responsible development of local <strong>Galapagos</strong> industries, encourage proactive planning<br />
and reduce species extinction risk through amelioration of unsustainable practice.<br />
