Young ScientistOutstanding Poster Presentati<strong>on</strong> AwardsHydrological, Ocean and Atmospheric Sciences YSOPP Awardsat Nice 2004 EGU Assembly were awarded to four yound scientists.The general aim of <strong>the</strong> Young Scientists’Outstanding Poster Paper (YSOPP) Award isto help to increase <strong>the</strong> general interest in <strong>the</strong> poster sessi<strong>on</strong>sat <strong>the</strong> EGU General Assemblies and to enhance <strong>the</strong>ir visibility,to fur<strong>the</strong>r improve <strong>the</strong> overall quality of poster presentati<strong>on</strong>sand most importantly, to foster <strong>the</strong> excitement of youngercolleagues in presenting <strong>the</strong>ir work in form of a poster.The awards are presented by <strong>the</strong> Divisi<strong>on</strong>s and Secti<strong>on</strong>sof <strong>the</strong> Uni<strong>on</strong>, but not all Divisi<strong>on</strong>s and Secti<strong>on</strong>s are presentlymaking this award. The Divisi<strong>on</strong>s and Secti<strong>on</strong>s presenting thisaward for <strong>the</strong> EGU 2004 Assembly are:--Divisi<strong>on</strong> <strong>on</strong> Hydrological Sciences--Divisi<strong>on</strong> <strong>on</strong> Atmospheric Sciences--Divisi<strong>on</strong> <strong>on</strong> Ocean SciencesThis year’s awardees for <strong>the</strong> Hydrological Sciences(HS):Karsten Täumer (karsten.taeumer@tu-berlin.de) received<strong>the</strong> award for his poster “Characteristics of water repellency –seas<strong>on</strong>al preferential flow occurrence”. Karsten Täumer worksin <strong>the</strong> research group “Interurban” at <strong>the</strong> Technical Universityof <strong>Berlin</strong> (Dept. of Soil Protecti<strong>on</strong>) which focuses <strong>on</strong> turnoverprocesses and water and solute transport <strong>on</strong> urban sites.Karsten’s focus is <strong>on</strong> <strong>the</strong> small scale heterogeneities (cm - m)in water transport and soil properties.Philip Brunner (brunner@ihw.baug.ethz.ch) received <strong>the</strong>award for his poster “Generating largescale soil salinity mapswith geophysics and remote sensing”. Philip Brunner worksat <strong>the</strong> Institute of Hydromechanics and Water ResourcesManagement (IHW), Department of Civil, Envir<strong>on</strong>mentaland Geomatics Engineering at <strong>the</strong> Swiss Federal Instituteof Technology (ETH) in Zurich. His Ph.D. project focuses <strong>on</strong>modelling water and salt fluxes through a agriculturally usedbasin in Xinjiang, China in order to understand and quantify <strong>the</strong>process of salinati<strong>on</strong>.Karsten Täumer andPhilip Brunner, 2004HS YSOPP Awardees.For <strong>the</strong> Atmospheric Sciences (AS), <strong>the</strong> awardee wasJohannes Quaas, for <strong>the</strong> poster entitled: Evaluati<strong>on</strong> of GCMparameterizati<strong>on</strong>s of cloud microphysics and aerosol indirecteffects using TOVS satellite data and ground-based remotesensing data of <strong>the</strong> SIRTA site, by Quaas, J et al.For <strong>the</strong> Oceas Sciences (OS), <strong>the</strong> 2004 award was givento Daniel Hayes (d.hayes@bas.ac.uk), for <strong>the</strong> poster entitled:Aut<strong>on</strong>omous underwater vehicle measurements underAntarctic sea ice, by Hayes, D.; Jenkins, A. and McPhail, S.Daniel Hayes was working at <strong>the</strong> British Antarctic Survey inCambridge, England.Eligible for <strong>the</strong> awards are MS and PhD students as wellas recent graduates (c<strong>on</strong>ferral of degree after 1 January of <strong>the</strong>year preceding <strong>the</strong> c<strong>on</strong>ference, i.e. 2004 for <strong>the</strong> next meetingin 2005) presenting <strong>the</strong>ir <strong>the</strong>sis work provided <strong>the</strong>y are <strong>the</strong> firstauthor and pers<strong>on</strong>ally present <strong>the</strong>ir poster at <strong>the</strong> c<strong>on</strong>ference.With <strong>the</strong> “Notice of Schedule” authors are informed about<strong>the</strong> final status of <strong>the</strong> presentati<strong>on</strong> of <strong>the</strong>ir paper: oral or poster.Young scientists meeting <strong>the</strong> criteria above and having beenselected to present a poster may register to participate in <strong>the</strong>YSOPP Award c<strong>on</strong>test of <strong>the</strong>ir respective Divisi<strong>on</strong> or Secti<strong>on</strong> byusing <strong>the</strong> link indicated. Thereby, registrati<strong>on</strong> with COSIS and<strong>the</strong> abstract ID-Nr. of <strong>the</strong> respective presentati<strong>on</strong> are required.The students name are <strong>the</strong>n be forwarded to coordinatorsof <strong>the</strong> respective Divisi<strong>on</strong> or Secti<strong>on</strong> toge<strong>the</strong>r with <strong>the</strong> e-mailaddress, poster title, abstract, abstract ID-Nr., sessi<strong>on</strong> nr.,poster board nr. and ‘<strong>on</strong>-display’ time.The coordinator sends out an email to all c<strong>on</strong>veners giving<strong>the</strong>m <strong>the</strong> names of <strong>the</strong> posters to be judged in <strong>the</strong>ir sessi<strong>on</strong>and asking <strong>the</strong>m to nominate two judges per poster before<strong>the</strong> meeting. The c<strong>on</strong>veners obtain prior c<strong>on</strong>sent from <strong>the</strong>judges and may choose to do part of <strong>the</strong> judging <strong>the</strong>mselves.The coordinator nominates two additi<strong>on</strong>al judges. To avoidpotential c<strong>on</strong>flicts of interest, judges should not be involved in<strong>the</strong> advising of that student in any way.Each coordinator prepares appraisal forms for each paperstating <strong>the</strong> title of <strong>the</strong> paper, <strong>the</strong> student’s name and <strong>the</strong> nameof <strong>the</strong> referee plus a number of criteria which are to be judgedby <strong>the</strong> referees regarding <strong>the</strong> scientific quality, <strong>the</strong> posterdesign and <strong>the</strong> ability to answer questi<strong>on</strong>s etc. with marks from0 to 10. The c<strong>on</strong>veners collect <strong>the</strong> forms at <strong>the</strong> Facility Desk in<strong>the</strong> poster area and hand <strong>the</strong>m to <strong>the</strong> judges during <strong>the</strong> postersessi<strong>on</strong>. The judges nominated by <strong>the</strong> coordinator collect <strong>the</strong>irforms directly from <strong>the</strong> Facility Desk.The judges evaluate <strong>the</strong> respective posters and fill in <strong>the</strong>THE EGGS 3


appraisal forms. Each judge is expected to actually speak to <strong>the</strong>student during <strong>the</strong> poster sessi<strong>on</strong>. This produces an additi<strong>on</strong>alb<strong>on</strong>us of getting some extra attenti<strong>on</strong> for each student. Thejudges are asked to work c<strong>on</strong>fidentially. The judges <strong>the</strong>n return<strong>the</strong>ir forms to an inbox at <strong>the</strong> EGU Facility Desk in <strong>the</strong> posterarea during <strong>the</strong> meeting or, if needed, by mail to <strong>the</strong> coordinator.The students are encouraged to submit a handout of <strong>the</strong>ir posterto <strong>the</strong> coordinator (ei<strong>the</strong>r during <strong>the</strong> meeting or by mail directlyafter <strong>the</strong> meeting.)After <strong>the</strong> meeting <strong>the</strong> coordinator will analyse <strong>the</strong> appraisalforms and compile a short list (about 20 posters) and a proposalof <strong>the</strong> ranking. A jury c<strong>on</strong>sisting of <strong>the</strong> chairs of <strong>the</strong> technicalcommittees and <strong>the</strong> coordinator as <strong>the</strong> chair of <strong>the</strong> jury willselect <strong>the</strong> top five posters and <strong>the</strong>se will get an award. Thefinal decisi<strong>on</strong> is made not later than about two m<strong>on</strong>ths after <strong>the</strong>meeting.Each awardee is notified after <strong>the</strong> decisi<strong>on</strong> has been made.The names are published <strong>on</strong> <strong>the</strong> EGU homepage and <strong>the</strong>awardees get <strong>the</strong> opportunity to post <strong>the</strong>ir posters electr<strong>on</strong>ically.The names are also be published in <strong>the</strong> present Newsletter, and<strong>the</strong>y receive a c<strong>on</strong>ference fee waiver for <strong>the</strong> next EGU GeneralAssembly. At <strong>the</strong> business meeting of <strong>the</strong> respective Divisi<strong>on</strong> orSecti<strong>on</strong> held at this General Assembly each awardee receivesa certificate of <strong>the</strong> award and is invited to submit a paper to <strong>on</strong>eof <strong>the</strong> EGU journals, termed <strong>the</strong> YSOPP paper.Our climate EditorShaocai Yu, has been <strong>the</strong> Climate editor of <strong>the</strong> Eggs since April 2003.Shaocai Yu, Chinese, born in 1964, hasbeen <strong>the</strong> Climate editor of <strong>the</strong> Eggs sinceApril 2003.He got his B.S. in chemistry from Peking University in1985 and Ph.D. in Atmospheric Sciences from North CarolinaState University in 1999.

<strong>European</strong> Mineral Sciences Initiative (EuroMinScI)The <strong>European</strong> Science Foundati<strong>on</strong> is launching a first Call for Proposals for research projects to beexecuted under <strong>the</strong> EUROCORES Programme <strong>European</strong> Mineral Sciences Initiative (EuroMinScI).Funding initiative for Research in MineralSciencesFollowing agreement with fundingagencies from Austria, Belgium, CzechRepublic, Est<strong>on</strong>ia, France, Germany,Hungary, Slovakia, Spain, Sweden, and<strong>the</strong> United Kingdom, <strong>the</strong> <strong>European</strong> ScienceFoundati<strong>on</strong> is launching a first Callfor Proposals for research projects tobe executed under <strong>the</strong> EUROCORESProgramme <strong>European</strong> Mineral SciencesInitiative (EuroMinScI). The EuroMinScIProgramme is expected to run for fiveyears and includes nati<strong>on</strong>al researchfunding and a <strong>European</strong> networkingcomp<strong>on</strong>ent.Scientific scope of <strong>the</strong> <strong>European</strong> MineralSciences InitiativeMajor advances in <strong>the</strong> use of physics-basedexperimental techniques (nuclearmagnetic res<strong>on</strong>ance spectroscopy,synchrotr<strong>on</strong> radiati<strong>on</strong>, neutr<strong>on</strong> scattering,ph<strong>on</strong><strong>on</strong> spectroscopy, laser-ablati<strong>on</strong>based techniques, etc.) and atomisticcomputer simulati<strong>on</strong> make it possibleto study mineral properties and behaviour.At <strong>the</strong> same time, measurementsof many minerals properties in situ atextreme c<strong>on</strong>diti<strong>on</strong>s of temperature andpressure corresp<strong>on</strong>ding to those existingin <strong>the</strong> earth’s interior are now feasible(e.g., <strong>the</strong> recent, experimental and<strong>the</strong>oretical determinati<strong>on</strong> of <strong>the</strong> temperatureat <strong>the</strong> inner core – outer coreboundary and <strong>the</strong> study of <strong>the</strong> Earth’score chemistry).The EUROCORES Programme EuroMinScIdraws toge<strong>the</strong>r <strong>the</strong> experimentaland computati<strong>on</strong>al activities, and <strong>the</strong>different experimental techniques, intointegrated research projects. Sometimesit calls for separate ‘computerexperiments’ while at o<strong>the</strong>r times computersimulati<strong>on</strong> is needed even to interpret<strong>the</strong> experimental data uniquely.It also addresses <strong>the</strong> need for youngresearchers with an academic backgroundin earth sciences to be trainedmore in <strong>the</strong> physics-based techniques,where <strong>the</strong> methods are very differentfrom traditi<strong>on</strong>al earth sciences. A “bottom-up”approach is envisaged, in whichparticipating scientists will propose <strong>the</strong>irown research projects within <strong>the</strong> broadc<strong>on</strong>text of EuroMinScI Programme.Specific directi<strong>on</strong>s of researchThe scientific c<strong>on</strong>tent of <strong>the</strong> EuroMinScIProgramme derives from <strong>the</strong>fact that <strong>the</strong> physical and chemicalproperties of <strong>the</strong> earth and terrestrialplanets depend <strong>on</strong> <strong>the</strong> properties of<strong>the</strong>ir c<strong>on</strong>stituent minerals. Interacti<strong>on</strong>sbetween <strong>the</strong> lithosphere and <strong>the</strong> atmosphere,biosphere or hydrosphere occuracross mineral surfaces. The chemistryof <strong>the</strong> crust/mantle/core depends <strong>on</strong>elements partiti<strong>on</strong>ing between minerals,and phenomena such as superplasticityor super-elasticity in mineralscould have a direct impact <strong>on</strong> largerscale geological processes, etc. TheEuroMinScI Programme will <strong>the</strong>reforefocus <strong>on</strong> <strong>the</strong> atomistic understandingof structures, properties and processesof minerals. Specific areas of researchthat can be supported include: Behaviourof minerals at high pressures andtemperatures; Structures and propertiesof amorphous and disordered materials;Defects and microstructures; Transportmechanisms at <strong>the</strong> atomic length scale;Trace elements and isotope partiti<strong>on</strong>ing;Structure, properties and reactivities ofmineral surfaces; Spectroscopy of mineralsand <strong>the</strong> quantitative interpretati<strong>on</strong>of spectra.BackgroundThe physics and chemistry of mineralswith <strong>the</strong>ir behaviour studied by integratingexperimental and computati<strong>on</strong>almethodsThis intitial suggesti<strong>on</strong> for a EURO-CORES programme related to <strong>the</strong> physicsand chemistry of minerals with <strong>the</strong>irbehaviour studied by integrating experimentaland computati<strong>on</strong>al methods canbe traced back to discussi<strong>on</strong>s at an ESFworkshop held in Rome in September2001, attended by <strong>the</strong> chairs of a numberof ESF networking activities in materialsciences.A document has been drafted after ameeting of interested scientists from 10countries in Frankfurt am Main, Germany<strong>on</strong> 28th October 2003.

<str<strong>on</strong>g>Report</str<strong>on</strong>g> <strong>on</strong> <strong>the</strong> JointAOGS Meeting & APHW C<strong>on</strong>ferenceThe newly founded Asia Oceanic Geosciences Society (AOGS) held its first Annual Meeting jointly with <strong>the</strong>Asia Pacific Associati<strong>on</strong> of Hydrology and Water Resources (APHW) having <strong>the</strong>ir sec<strong>on</strong>d c<strong>on</strong>ference- Peter Fabian reports.July 14, 2004.- The newly founded Asia Oceanic GeosciencesSociety (AOGS) held its first Annual Meeting jointlywith <strong>the</strong> Asia Pacific Associati<strong>on</strong> of Hydrology and Water Resources(APHW) having <strong>the</strong>ir sec<strong>on</strong>d c<strong>on</strong>ference. The meetingand C<strong>on</strong>ference took place in Singapore, 5-9 July 2004.As Wing-Huen Ip, <strong>the</strong> AOGS President, made it clear in hisopening speech, <strong>the</strong> former Euro-pean Geophysical Society(EGS) was viewed as a suitable model for AOGS, since it alsohad to be developed from a standing start without funds or anykind of existing framework. Ip pointed out: “The success fo <strong>the</strong>EGS is well known, and we make no apologies for borrow-ingheavily from its example. In particular we have endeavouredto organize a bottom up so-ciety devoted to <strong>the</strong> interest of scienceand scientists, from a start, without <strong>the</strong> c<strong>on</strong>traints thatmight hamper <strong>the</strong> development of a politically based organizati<strong>on</strong>representing nati<strong>on</strong>al inter-ests.”During four days (Tuesday-Friday, M<strong>on</strong>day July 5 was devotedto registrati<strong>on</strong> and <strong>Open</strong>ing Cerem<strong>on</strong>y <strong>on</strong>ly) sessi<strong>on</strong>s<strong>on</strong> Solid Earth (SE), Oceans and Atmospheres (OA), SolarTerres-trials (ST), Plenatary Science (PS) and InterdisciplinaryWorking Groups wre held. Hydro-logical Science (HS) was essentiallyprovided by APHW. The scientific spectrum was similarto that of EGU, with ST and PS dominating while OA beingcomparable weak.About 1000 scientists attended, with China, India, Koreaand Japan dominating and ast<strong>on</strong>ish-ing many participants fromEurope and <strong>the</strong> US as well. The mix was just right to set <strong>the</strong>scene for many highly exciting sessi<strong>on</strong>s. A perfect organizati<strong>on</strong>and a very c<strong>on</strong>venient C<strong>on</strong>venti<strong>on</strong> Center made a smooth andefficient c<strong>on</strong>ference possible. Overall, <strong>the</strong> First AOGS AnnualMeeting was a great success to which <strong>the</strong> organizers can bec<strong>on</strong>gratulated.Given <strong>the</strong> large potential of <strong>the</strong> Asia-Oceanic regi<strong>on</strong> and<strong>the</strong> positive impressi<strong>on</strong> of this first meeting, <strong>the</strong> newly foundedAOGS is bound to grow and successfully develop. The nextAOGS Annual Meeting will take place June 20-24, 2005 in Singapore.Peter FabianEGU PresidentRosetta: Self-portrait and view of homeESA’s Rosetta comet-chaser has photographed itself in space at a distanceof 35 milli<strong>on</strong> kilometres from Earth.

Yuh<strong>on</strong>g Fan, “Magnetic Fields in <strong>the</strong> SolarC<strong>on</strong>vecti<strong>on</strong> Z<strong>on</strong>e” (incl. 142 references,19 figures and 4 movies)ABSTRACTRecent studies of <strong>the</strong> dynamic evoluti<strong>on</strong> of magnetic fluxtubes in <strong>the</strong> solar c<strong>on</strong>vecti<strong>on</strong> z<strong>on</strong>e are reviewed with focus <strong>on</strong>emerging flux tubes resp<strong>on</strong>sible for <strong>the</strong> formati<strong>on</strong> of solar activeregi<strong>on</strong>s. The current prevailing picture is that active regi<strong>on</strong>s<strong>on</strong> <strong>the</strong> solar surface originate from str<strong>on</strong>g toroidal magneticfields generated by <strong>the</strong> solar dynamo mechanism at <strong>the</strong> thintachocline layer at <strong>the</strong> base of <strong>the</strong> solar c<strong>on</strong>vecti<strong>on</strong> z<strong>on</strong>e. Thus<strong>the</strong> magnetic fields need to traverse <strong>the</strong> entire c<strong>on</strong>vecti<strong>on</strong> z<strong>on</strong>ebefore <strong>the</strong>y reach <strong>the</strong> photosphere to form <strong>the</strong> observed solaractive regi<strong>on</strong>s. This review discusses results with regard to<strong>the</strong> following major topics: 1. <strong>the</strong> equilibrium properties of <strong>the</strong>toroidal magnetic fields stored in <strong>the</strong> stable overshoot regi<strong>on</strong>at <strong>the</strong> base of <strong>the</strong> c<strong>on</strong>vecti<strong>on</strong> z<strong>on</strong>e, 2. <strong>the</strong> buoyancy instabilityassociated with <strong>the</strong> toroidal magnetic fields and <strong>the</strong> formati<strong>on</strong>of buoyant magnetic flux tubes, 3. <strong>the</strong> rise of emerging fluxloops through <strong>the</strong> solar c<strong>on</strong>vective envelope as modeled by<strong>the</strong> thin flux tube calculati<strong>on</strong>s which infer that <strong>the</strong> field strengthof <strong>the</strong> toroidal magnetic fields at <strong>the</strong> base of <strong>the</strong> solar c<strong>on</strong>vecti<strong>on</strong>z<strong>on</strong>e is significantly higher than <strong>the</strong> value in equipartiti<strong>on</strong>with c<strong>on</strong>vecti<strong>on</strong>, 4. <strong>the</strong> minimum twist needed for maintainingcohesi<strong>on</strong> of <strong>the</strong> rising flux tubes, 5. <strong>the</strong> rise of highly twistedkink unstable flux tubes as a possible origin of $\delta$-sunspots,6. <strong>the</strong> evoluti<strong>on</strong> of buoyant magnetic flux tubes in 3Dstratified c<strong>on</strong>vecti<strong>on</strong>, 7. turbulent pumping of magnetic flux bypenetrative compressible c<strong>on</strong>vecti<strong>on</strong>, 8. an alternative mechanismfor intensifying toroidal magnetic fields to significantly super-equipartiti<strong>on</strong>field strengths by c<strong>on</strong>versi<strong>on</strong> of <strong>the</strong> potentialenergy associated with <strong>the</strong> superadiabatic stratificati<strong>on</strong> of <strong>the</strong>solar c<strong>on</strong>vecti<strong>on</strong> z<strong>on</strong>e, and finally 9. a brief overview of ourcurrent understanding of flux emergence at <strong>the</strong> surface andpost-emergence evoluti<strong>on</strong> of <strong>the</strong> subsurface magnetic fields.FULL ARTICLE AT:http://www.livingreviews.org/lrsp-2004-1Brian E. Wood, “Astrospheres and SolarlikeStellar Winds” (incl. 156 references and13 figures)ABSTRACTStellar analogs for <strong>the</strong> solar wind have proven to be frustratinglydifficult to detect directly. However, <strong>the</strong>se stellar windscan be studied indirectly by observing <strong>the</strong> interacti<strong>on</strong> regi<strong>on</strong>scarved out by <strong>the</strong> collisi<strong>on</strong>s between <strong>the</strong>se winds and <strong>the</strong> interstellarmedium (ISM). These interacti<strong>on</strong> regi<strong>on</strong>s are called ``astrospheres’’,analogous to <strong>the</strong> ``heliosphere’’ surrounding <strong>the</strong>Sun. The heliosphere and astrospheres c<strong>on</strong>tain a populati<strong>on</strong>of hydrogen heated by charge exchange processes that canproduce enough H~I Ly$\alpha$ absorpti<strong>on</strong> to be detectable inUV spectra of nearby stars from <strong>the</strong> Hubble Space Telescope(HST). The amount of astrospheric absorpti<strong>on</strong> is a diagnosticfor <strong>the</strong> strength of <strong>the</strong> stellar wind, so <strong>the</strong>se observati<strong>on</strong>s haveprovided <strong>the</strong> first measurements of solar-like stellar winds. Resultsfrom <strong>the</strong>se stellar wind studies and <strong>the</strong>ir implicati<strong>on</strong>s forour understanding of <strong>the</strong> solar wind are reviewed here. Ofparticular interest are results c<strong>on</strong>cerning <strong>the</strong> past history of <strong>the</strong>solar wind and its impact <strong>on</strong> planetary atmospheres.FULL ARTICLE AT:http://www.livingreviews.org/lrsp-2004-2Sami K. SolankiName change for <strong>the</strong> Max Planck Institute for Aer<strong>on</strong>omyA letter from <strong>the</strong> Managing Director informs about name changefor <strong>the</strong> MPI for Aer<strong>on</strong>omy in Katlenburg-Lindau, Germany.24 June 2004.- A letter from <strong>the</strong> Managing Director informsabout name change for <strong>the</strong> MPI for Aer<strong>on</strong>omy in Katlenburg-Lindau,Germany:Dear Madam, dear Sir,Please allow me to inform you of an imminent developmentc<strong>on</strong>cerning our Institute. This Institute, which has existed since1957 under <strong>the</strong> name Max Planck Institute for Aer<strong>on</strong>omy, hasseen a number of transformati<strong>on</strong>s in its lifetime. During <strong>the</strong>50’s and 60’s, <strong>the</strong> scientific emphasis was <strong>on</strong> <strong>the</strong> explorati<strong>on</strong>of <strong>the</strong> Earth’s upper atmosphere, but in <strong>the</strong> following decadesthis was extended to include new areas involving <strong>the</strong> solar system.The current thrust of our research now c<strong>on</strong>centrates <strong>on</strong><strong>the</strong> explorati<strong>on</strong> of <strong>the</strong> Sun, Heliosphere, planets, and comets,that is, <strong>on</strong> all <strong>the</strong> essential parts of our solar system. With <strong>the</strong>retirement of Prof. Sir Ian Axford and Prof. Tor Hagfors andwith <strong>the</strong> appointment of Prof. Ulrich Christensen and myself,this new thrust is reflected in <strong>the</strong> directorship as well. This developmentwill for <strong>the</strong> time being, culminate with <strong>the</strong> retirementof Dr. Helmut Rosenbauer <strong>on</strong> 30th June 2004.In order to more accurate by reflect our Institute’s currentactivities, <strong>the</strong> Max Planck Society has accepted our proposalto change <strong>the</strong> name, effective 1st July 2004, to “Max-Planck-Institut für S<strong>on</strong>nensystemforschung” (in English, Max PlanckInstitute for Solar System Research). The renaming is coupledwith <strong>the</strong> introducti<strong>on</strong> of a new logo, which we hope will increase<strong>the</strong> Institute’s visibility.We shall make every effort to maintain <strong>the</strong> good reputati<strong>on</strong>of our Institute under <strong>the</strong> new name and “outfit”, and wherepossible, to enhance it. We look forward to many more successfulcollaborati<strong>on</strong>s.Sincerely yours,Prof. Dr. Sami K. SolankiManaging Director, MPI for Solar System ResearchTHE EGGS 9

500,000 year-old sediment coresfrom <strong>the</strong> bottom of <strong>the</strong> Mediterranean SeaWithin <strong>the</strong> €3,6 milli<strong>on</strong> EU research project PROMESS1 (PROfiles across MEditerranean SedimentarySystems), with a EU €2,7 milli<strong>on</strong> c<strong>on</strong>tributi<strong>on</strong>, <strong>European</strong> scientists have collected 500,000year-old sediment cores from <strong>the</strong> bottom of <strong>the</strong> Mediterranean Sea. These samples will allowresearchers to better rec<strong>on</strong>struct climate variati<strong>on</strong>s since pre-historic times. PROMESS1 involvespartners from France, Germany, Italy, Spain, <strong>the</strong> Ne<strong>the</strong>rlands and <strong>the</strong> United Kingdom.Brussels, 22 July 2004.-Between June, 24th and July, 22nd,2004, a team of <strong>European</strong> scientistsembarked <strong>on</strong> a drilling expediti<strong>on</strong> in <strong>the</strong>Mediterranean Sea , from Brindisi (Italy)to Barcel<strong>on</strong>a (Spain). The purpose ofthis cruise was to collect, for <strong>the</strong> firsttime, l<strong>on</strong>g (up to 300 m) sediment secti<strong>on</strong>sand measurements from two deltaicmargins where <strong>the</strong> memory of globalchanges during <strong>the</strong> last ca. 500,000years is particularly well preserved. Thecruise was part of <strong>the</strong> PROMESS1 project.PROMESS1 has three main objectives:1. The rec<strong>on</strong>structi<strong>on</strong> of sea-leveland climate changes during <strong>the</strong> last 500000 years2. The analysis of <strong>the</strong> impact ofglobal changes <strong>on</strong> slope stability, andexaminati<strong>on</strong> of slope processes such asunderwater avalanches3. The understanding of <strong>the</strong> processesthat form strata <strong>on</strong> c<strong>on</strong>tinental margins,in relati<strong>on</strong> with sea-level changes,instabilities and oceanic processes, andrecent tect<strong>on</strong>ic activities.As <strong>the</strong> partners of <strong>the</strong> project state,“The increasing interest in c<strong>on</strong>tinentalmargins and deep marine envir<strong>on</strong>mentsrequires an integrated approach (fromsource to sink) to <strong>the</strong> study of processesforming sedimentary systems. The majorc<strong>on</strong>trolling processes that need to befur<strong>the</strong>r investigated include changes inglobal sea-level, oceanographic regimeand sediment fluxes (str<strong>on</strong>gly influencedby climate variability), as well as slopefailure and tect<strong>on</strong>ics s.l. (subsidence,earthquakes,..). Understanding <strong>the</strong>seprocesses during <strong>the</strong> Quaternary hasimportant implicati<strong>on</strong>s for managing sustainableuse of deeper marine envir<strong>on</strong>ments,<strong>the</strong> explorati<strong>on</strong> of analogue sandbodies by <strong>the</strong> oil industry, and for understandingand predicting geohazards.Only Large Infrastructure Researchsuch as drilling vessels, not accessibleto <strong>on</strong>e given country or institute can permitto fully exploit <strong>the</strong> huge backgroundof geophysical data and interpretati<strong>on</strong>sthat has been ga<strong>the</strong>red <strong>on</strong> Mediterraneansubaquatic deltaic systems. So far,very few, if any, l<strong>on</strong>g cores and in situmeasurements have provided “groundtruth”to <strong>the</strong>se interpretati<strong>on</strong>s, but thistype of geologic data is absolutely necessaryto characterise and quantify <strong>the</strong>processes and time-scales in order tofur<strong>the</strong>r implement numerical and experimentalmodels of margin evoluti<strong>on</strong>.”Cross-examinati<strong>on</strong> of data from differentsources will help better understandclimate variati<strong>on</strong>s. The data ofPROMESS1 will be compared with dataprovided by ice core drilling.PROMESS1 has also been supportedwith technical advice by <strong>the</strong> IntegratedOcean Drilling Programme (IODP).Offshore drilling is expensive and it ismainly undertaken by <strong>the</strong> offshore oiland gas industry. IODP is an excepti<strong>on</strong>,aiming at providing to <strong>the</strong> internati<strong>on</strong>alscientific community drilling platformscapable to drill in extreme c<strong>on</strong>diti<strong>on</strong>s,in terms of water depth and penetrati<strong>on</strong>below sea floor, to address issues suchas global changes, earthquakes, anddeep biosphere. The <strong>European</strong> Uni<strong>on</strong>participates to IODP with <strong>the</strong> ECORD(<strong>European</strong> C<strong>on</strong>sortium for Ocean Drilling)project.During <strong>the</strong> last expediti<strong>on</strong>, <strong>the</strong>shipboard party reports:“Wednesday, July 21st, 17h00 localtime.- This is <strong>the</strong> last newsletter sentfrom “SRV Bavenit”, since we are goingto reach Barcel<strong>on</strong>a, our demobilisati<strong>on</strong>harbour, <strong>on</strong> July 21st, evening.We reached PRGL2, <strong>the</strong> last site ofPROMESS 1, <strong>on</strong> July, 18th, at 8:00 AM.This site is situated at <strong>the</strong> seaward terminati<strong>on</strong>of <strong>the</strong> Last Glacial Maximumshoreline, at a water depth of 103 m.The targeted depth was 100 m belowsea-floor, in order to sample shelf sequencesthat were deposited during <strong>the</strong>same time interval as at PRGL1 (500 kyraccording to seismic interpretati<strong>on</strong> andstratigraphic modelling).The objective at this site is to characterize<strong>the</strong> very diverse seismic faciesin terms of paleoenvir<strong>on</strong>ments, paleowaterdepths and sedimentary processes.To <strong>the</strong> difference of GL1 wherec<strong>on</strong>tinuous sedimentati<strong>on</strong> occurred,PRGL2 was successively emerged andsubmerged. It is <strong>the</strong>refore characterizedby several disc<strong>on</strong>tinuities related to submarineand/or subaerial erosi<strong>on</strong>. Verynicely preserved clinoforms, up to 35 mthick, were interpreted as <strong>the</strong> witnessesof former shorefaces/shorelines formedduring glacial periods. They representinteresting Quaternary analogues toseveral oil reservoirs. They are separatedby seismic facies suggesting finergrained sedimentati<strong>on</strong>, some of <strong>the</strong>m affectedby wavy features similar to thatobserved at PRAD2 in <strong>the</strong> Adriatic Sea.The high amount of sand expected atPRGL2 made it challenging from a technicalpoint of view, sand being very difficultto recover. For this reas<strong>on</strong>, it wasdecided to start <strong>the</strong> operati<strong>on</strong>s with ageotechnical drilling (PRGL2-1), in orderto obtain a first estimate of lithologyand better adapt <strong>the</strong> coring strategy byselecting <strong>the</strong> best adapted tools.The CPT test was achieved at 2:00AM <strong>on</strong> July, 19th. Some of <strong>the</strong> layers(less than 5m in total) encounteredwere so stiff that it was not possible toget through, <strong>the</strong> corresp<strong>on</strong>ding intervalsTHE EGGS 11


were drilled without measurement.The sec<strong>on</strong>d hole (PRGL2-2) wasdevoted to coring. As expected, we encountereddifficulties with very compactsands, especially around 75 mbsf. Inthis case, <strong>the</strong> strategy was to core asmuch as possible (sometimes less than20 cm), <strong>the</strong>n to drill 50 cm lower than <strong>the</strong>top of <strong>the</strong> previously cored interval. Onaverage, <strong>the</strong> recovery at site PRGL2-2was about 82%, a ra<strong>the</strong>r satisfying resultc<strong>on</strong>sidering <strong>the</strong> lithologies. It is worthnoting that CPTU, which is comm<strong>on</strong>lyemployed by <strong>the</strong> industry but almost unknownby <strong>the</strong> n<strong>on</strong>-geotechnical world, isvery useful not <strong>on</strong>ly for characterizing insitu physical properties of sediment, butalso for predicting lithologies, and betteradapt sampling strategies.After sampling PRGL2-2 was loggedwith gamma-ray tool within <strong>the</strong> drill pipe(<strong>the</strong> large amount of sand did not allowlogging in open hole). The loggingwinch being broken, it was necessary tohandle <strong>the</strong> cable by hand (by chance,this didn’t happen at <strong>the</strong> deepest site,PRGL1). Operati<strong>on</strong>s finished at 22h20,<strong>on</strong> July, 20th.We are now sailing toward Barcel<strong>on</strong>a,packing up equipments and data,and wrapping up <strong>the</strong> preliminary cruisereport. The last 13 days were quite intense,all <strong>the</strong> group is quite tired but veryhappy of a 27-day cruise which wentvery well, with a huge amount of uniquedata to valorise.”For fur<strong>the</strong>r informati<strong>on</strong> <strong>on</strong>PROMESS1, see:http://promess1.wdc-mare.org/Sources:EC, © <strong>European</strong> Communities,1995-2004PROMESS1 websiteTHE EGGS 12


Extrapolating future Arctic oz<strong>on</strong>e lossesTrends in stratospheric temperature might delay oz<strong>on</strong>e recoveryFuture increases in <strong>the</strong> c<strong>on</strong>centrati<strong>on</strong> ofgreenhouse gases and water vapour are likelyto cool <strong>the</strong> stratosphere fur<strong>the</strong>r and to increase <strong>the</strong> amountof polar stratospheric clouds (PSCs). Future Arctic PSC areashave been extrapolated using <strong>the</strong> highly significant trends in <strong>the</strong>temperature record from 1958–2001. Using a tight correlati<strong>on</strong>between PSC area and <strong>the</strong> total vortex oz<strong>on</strong>e depleti<strong>on</strong> andtaking <strong>the</strong> decreasing amounts of oz<strong>on</strong>e depleting substancesinto account we make empirical estimates of future oz<strong>on</strong>e. Theresult is that Arctic oz<strong>on</strong>e losses increase until 2010–2020 and<strong>on</strong>ly decrease slightly up to 2030.

Impact of vegetati<strong>on</strong> fires <strong>on</strong>compositi<strong>on</strong> and circulati<strong>on</strong> of <strong>the</strong>atmosphere (EFEU)S. Wurzler et al. report <strong>on</strong> <strong>the</strong> AFO2000 projectThe project addresses <strong>the</strong> c<strong>on</strong>tributi<strong>on</strong> of vegetati<strong>on</strong> fires to <strong>the</strong> local trace gas and particle budgets of <strong>the</strong>troposphere and <strong>the</strong> lower stratosphere, <strong>the</strong>ir direct and indirect radiative impact, <strong>the</strong>ir impact <strong>on</strong> cloud formati<strong>on</strong>and chemical and microphysical processes in clouds.Scientific objectivesVegetati<strong>on</strong> fires are a significant source for atmospherictrace gases and aerosol particles (AP) <strong>on</strong> both local and globalscale. Vast fires regularly occur in <strong>the</strong> tropics (Africa, SouthAmerica, and South East Asia) as well as in <strong>the</strong> mid latitudesand boreal regi<strong>on</strong>s (<strong>the</strong> Mediterranean regi<strong>on</strong>, USA, Canada,Scandinavia, and Russia). Fire emissi<strong>on</strong>s and <strong>the</strong>ir reacti<strong>on</strong>products are transported by c<strong>on</strong>vecti<strong>on</strong> into <strong>the</strong> free troposphereand <strong>the</strong> lower stratosphere and are distributed from <strong>the</strong>local scale to <strong>the</strong> mesoscale and even to <strong>the</strong> global scale.Particles and gases from vegetati<strong>on</strong> fires and <strong>the</strong>ir sec<strong>on</strong>daryproducts change <strong>the</strong> chemical compositi<strong>on</strong> of <strong>the</strong> atmosphere.Their influence <strong>on</strong> cloud microphysics (Fig. 1) maylead to warm precipitati<strong>on</strong> suppressi<strong>on</strong> and a vertical shift in<strong>the</strong> release of latent heat. This has significant effects <strong>on</strong> <strong>the</strong>atmospheric energy and radiati<strong>on</strong> budget (direct and indirecteffects) and potentially <strong>on</strong> <strong>the</strong> global circulati<strong>on</strong>. Fig. 2 summarizes<strong>the</strong> various processes c<strong>on</strong>nected with biomass burningand <strong>the</strong>ir interacti<strong>on</strong>s <strong>on</strong> different scales.The joint research project EFEU addresses <strong>the</strong> followingquesti<strong>on</strong>s:1. What is <strong>the</strong> c<strong>on</strong>tributi<strong>on</strong> of vegetati<strong>on</strong> fires to <strong>the</strong> localtrace gas and particle budgets of <strong>the</strong> troposphere and <strong>the</strong> lowerstratosphere?2. To which extent do aerosols emitted from vegetati<strong>on</strong> firesaffect <strong>the</strong> radiati<strong>on</strong> budget of <strong>the</strong> atmosphere (direct effect)?3. How does vertical transport of fire emissi<strong>on</strong>s into <strong>the</strong> up-Figure 1.Cloudsforming in<strong>the</strong> plume ofa vegetati<strong>on</strong>fire (photo:Wurzler).THE EGGS 14

How relevant is <strong>the</strong> change of microphysical propertiescaused by aerosols from biomass burning for <strong>the</strong> regi<strong>on</strong>al radiati<strong>on</strong>(indirect effect) and energy budgets of <strong>the</strong> atmosphereand <strong>the</strong> small-scale atmospheric circulati<strong>on</strong>?MethodsThese questi<strong>on</strong>s are addressed with a combined experimentaland numerical approach drawing from <strong>the</strong> expertiseof eight different research groups. The experimental part isdesigned to enhance <strong>the</strong> database <strong>on</strong> biomass burning emissi<strong>on</strong>swith a particular focus <strong>on</strong> <strong>the</strong> suite of input parametersrequired by <strong>the</strong> numerical models employed in <strong>the</strong> EFEU project.C<strong>on</strong>trolled burn experiments were performed with varioustypes of typical biomass burning fuel ranging from central <strong>European</strong>to tropical fuel types. During <strong>the</strong>se experiments physical,optical and chemical particulate parameters as well as alimited number of gas phase species are characterized. Am<strong>on</strong>g<strong>the</strong> measurement parameters are:• optical absorpti<strong>on</strong> and scattering coefficients of aerosolparticles• total particle c<strong>on</strong>centrati<strong>on</strong> and number size distributi<strong>on</strong>(12 nm to 10,000 nm in diameter)• morphological and chemical characterizati<strong>on</strong> of aerosolparticles by single particle analysis• bulk and size resolved chemical and mass characterizati<strong>on</strong>of particulate matter• hygroscopic growth factors of <strong>the</strong> particles and CCN/CNratios• trace gas abundances of NO, CO and CO2Two series of laboratory experiments took place in May/June 2002 and June 2003 at <strong>the</strong> laboratory oven of <strong>the</strong> MPIMainz (see Fig. 3). While in <strong>the</strong> first campaign, African (e.g.,acacia, musasa, mupangara) and Mediterranean (e.g., aleppopine, kermes oak) vegetati<strong>on</strong> has been investigated, <strong>the</strong> sec<strong>on</strong>dcampaign focused <strong>on</strong> biomass from boreal regi<strong>on</strong>s (oak,spruce, pine; partly with dry or green material). A third campaignwas carried out in September 2003 in order to establishreproducibility of <strong>the</strong> measurements and to investigate emissi<strong>on</strong>sfrom Ind<strong>on</strong>esian and German peat fires.A hierarchically structured suite of originally independentnumerical models is employed to investigate <strong>the</strong> complex impactof biomass burning emissi<strong>on</strong>s <strong>on</strong> <strong>the</strong> atmosphere. Thevarious model comp<strong>on</strong>ents complement each o<strong>the</strong>r address-Figure 3.

ing different aspects of this topic <strong>on</strong> a range of spatial and temporalscales. Combined with <strong>the</strong> input data from <strong>the</strong> laboratoryexperiments this integrated approach allows a more completeview <strong>on</strong> physical, chemical and dynamical aspects of biomassburning plumes. The model hierarchy facilitates seamlesstransiti<strong>on</strong> from microscale to regi<strong>on</strong>al scale models and spans<strong>the</strong> temporal scale from a few minutes to m<strong>on</strong>ths and years.Am<strong>on</strong>g o<strong>the</strong>r aspects <strong>the</strong> modelling efforts address:• impact of biomass burning aerosol <strong>on</strong> cloud microphysicsand precipitati<strong>on</strong> using detailed and parameterized model approachesincluding <strong>the</strong> ice phase• evoluti<strong>on</strong> of individual biomass burning plumes, c<strong>on</strong>sideringdynamical evoluti<strong>on</strong> and troposphere-stratosphere exchangeof emissi<strong>on</strong>s as well as chemical processes in youngplumes• effect of radiative transport <strong>on</strong> chemistry and dynamics of<strong>the</strong> atmosphere and determinati<strong>on</strong> of <strong>the</strong> role of biomass burning<strong>on</strong> <strong>the</strong> regi<strong>on</strong>al climate• effect of biomass burning <strong>on</strong> <strong>the</strong> atmospheric budgets oftrace c<strong>on</strong>stituents, water, and energy <strong>on</strong> <strong>the</strong> regi<strong>on</strong>al scaleSelected resultsOptical properties of <strong>the</strong> biomass burning aerosol: Modelling<strong>the</strong> impact of vegetati<strong>on</strong> fires <strong>on</strong> radiative transport requiresaccurate knowledge of <strong>the</strong> optical properties of biomass burningaerosol. Optical properties of particles are well describedby Mie <strong>the</strong>ory and mainly depend <strong>on</strong> particle size, shape, andindex of refracti<strong>on</strong> m. However, for biomass burning aerosolespecially m is not well known. The EFEU data set provides<strong>the</strong> unique opportunity to investigate m for various fuel typesand burning c<strong>on</strong>diti<strong>on</strong>s. As an example Fig. 4 shows 2-minuteaverages of <strong>the</strong> measured SSA (single scattering albedo = ratioof scattering and extincti<strong>on</strong> coefficient) at a wavelength of550 nm of about 9-minutes old biomass burning aerosol froman oak (dry) fire; <strong>the</strong> corresp<strong>on</strong>ding burning c<strong>on</strong>diti<strong>on</strong>s are alsoshown as dCO/dCO2 trace (crosses), where dCO and dCO2represent CO and CO2 c<strong>on</strong>centrati<strong>on</strong>s above background levels.There was an obvious positive correlati<strong>on</strong> between SSAand dCO/dCO2. In <strong>the</strong> smouldering phase at <strong>the</strong> beginningof <strong>the</strong> experiment (dCO/dCO2 > 8%) SSA was very high withvalues around 0.95. With <strong>the</strong> start of <strong>the</strong> flaming combusti<strong>on</strong>(dCO/dCO2 < 8%) at 11:33 SSA showed a sharp decreaseFigure 4. Comparis<strong>on</strong> between measured and modelled singlescattering albedo (SSA) for a 1-hour fire with dry oak as fuel.down to approximately 0.7 followed by a relatively steady increaseto just above 0.9 accompanied by an increase in dCO/dCO2.For comparis<strong>on</strong>, Fig. 4 also shows Mie calculati<strong>on</strong>s of <strong>the</strong>SSA for three different black carb<strong>on</strong> (BC) mass fracti<strong>on</strong>s based<strong>on</strong> <strong>the</strong> measured number size distributi<strong>on</strong>s under <strong>the</strong> assumpti<strong>on</strong>of spherical particle shape which is justified by SEM pictures.Due to <strong>the</strong> significantly lower volatility of black carb<strong>on</strong>(BC) compared to organic carb<strong>on</strong> (OC) we performed <strong>the</strong> Miecalculati<strong>on</strong>s for coated spheres with a BC core (mBC = 1.75-0.44i) and an OC shell (mOC = 1.53-0.0i). Fig. 4 shows that<strong>the</strong> modelled SSA is fairly c<strong>on</strong>stant for each BC mass fracti<strong>on</strong>.Hence, changes in size distributi<strong>on</strong> al<strong>on</strong>e cannot explain <strong>the</strong>observed variati<strong>on</strong>s in SSA which indicates a significant role ofparticle chemistry and hence m. We found that BC mass fracti<strong>on</strong>sof 2 and 20% represent <strong>the</strong> observed extreme SSA valuesof about 0.95 and 0.7, respectively, reas<strong>on</strong>ably well. Thisis c<strong>on</strong>sistent with <strong>the</strong> expected higher BC c<strong>on</strong>tent for moreflaming fires (lower dCO/dCO2 values) which produce highercombusti<strong>on</strong> temperatures and c<strong>on</strong>sequently more soot. Hence,our results suggest that young biomass burning aerosol maybe modelled as BC spheres coated with a variable amount ofOC depending <strong>on</strong> <strong>the</strong> burning c<strong>on</strong>diti<strong>on</strong>s. Similar Mie calculati<strong>on</strong>swill be performed for all of <strong>the</strong> wood types investigated in<strong>the</strong> EFEU laboratory campaign and <strong>the</strong>n hopefully c<strong>on</strong>densedinto a single parameterizati<strong>on</strong> at least for certain categories ofwood (e.g. nor<strong>the</strong>rn boreal, tropical, peat, etc.).Drop nucleati<strong>on</strong> ability of <strong>the</strong> aerosol particles: As a step for<strong>the</strong> understanding of <strong>the</strong> influence of biomass burning aerosol<strong>on</strong> cloud formati<strong>on</strong>, potential cloud c<strong>on</strong>densati<strong>on</strong> nuclei (CCN)were identified by determining <strong>the</strong> CCN/CN ratio in <strong>the</strong> laboratoryexperiments. This was d<strong>on</strong>e for different dry particle sizes(50, 100, 150, 250, and 325 nm) at different supersaturati<strong>on</strong>sfrom 0.24 to 1.64 %. The experimental results are compared tocritical supersaturati<strong>on</strong>s calculated from extended Köhler <strong>the</strong>orywhich is also used in <strong>the</strong> detailed microphysical models appliedin <strong>the</strong> project. Fig. 5 shows <strong>the</strong> critical supersaturati<strong>on</strong> forvarying e (soluble fracti<strong>on</strong>, here amm<strong>on</strong>ium sulphate) and APsizes (lines with different colors). CCN/CN ratios of 25 (circles),50 (squares), 75 (diam<strong>on</strong>ds), and 100 % (triangles) are deducedfrom <strong>the</strong> measurements and compared to <strong>the</strong> <strong>the</strong>oreticalvalues. The black square <strong>on</strong> <strong>the</strong> red line means, e.g., that50 % of <strong>the</strong> 100 nm AP are activated at 0.46 % supersaturati<strong>on</strong>which corresp<strong>on</strong>ds to a <strong>the</strong>oretical value of e = 0.08. One cansee that <strong>the</strong> soluble fracti<strong>on</strong> generally is small (e < 10 % forabout 50 % of <strong>the</strong> particles) as it is expected for biomass burningAP and that e is slightly higher for smaller AP sizes (50 nmvs. 150 nm). Despite <strong>the</strong>ir small e, larger particles (150, 200nm) are activated at relatively low supersaturati<strong>on</strong>s that easilycould be reached in clouds. Obviously, <strong>the</strong> critical supersaturati<strong>on</strong>sare very sensitive to e < 20 % especially for smaller sizes(50, 100 nm). Therefore, small changes in epsil<strong>on</strong> could highlyinfluence <strong>the</strong> number of drops in clouds affected by biomassburning. The CCN/CN ratios are quite similar for <strong>the</strong> differentwood types (spruce, pine, oak, and musasa) c<strong>on</strong>sidered in <strong>the</strong>EFEU experiments.Modelling results from <strong>the</strong> regi<strong>on</strong>al model REMO: Thespatial distributi<strong>on</strong> of smoke haze in Ind<strong>on</strong>esia in 1997 canbe derived from <strong>the</strong> TOMS Aerosol Index (AI) data, shown asm<strong>on</strong>thly mean in <strong>the</strong> upper part of Fig. 6. During <strong>the</strong> smokehaze period maximum intensity in TOMS AI data is visible in<strong>the</strong> provinces of South Sumatra, Jambi, Central and West Kalimantan,and <strong>on</strong> Irian Jaya, where <strong>the</strong> main peat fire emissi<strong>on</strong>THE EGGS 16


areas are located. Large scale transport from <strong>the</strong>se source regi<strong>on</strong>sto nor<strong>the</strong>rn and western directi<strong>on</strong>s reaching into <strong>the</strong> IndianOcean occurred especially during September 1997, when<strong>the</strong> fire emissi<strong>on</strong>s were highest and rainfall and associated wetdepositi<strong>on</strong> was lowest.The lower part of Fig. 6 presents <strong>the</strong> m<strong>on</strong>thly mean atmosphericcolumn burden in mg(C)/m2 of total particulate matter(TPM) as determined by <strong>the</strong> regi<strong>on</strong>al model REMO. It shouldbe emphasised at this point that Fig. 6 displays <strong>on</strong>ly a qualitativecomparis<strong>on</strong> of TOMS AI with REMO calculated TPM inorder to evaluate <strong>the</strong> simulated temporal and spatial distributi<strong>on</strong>of smoke haze. The principle ability of <strong>the</strong> REMO modelto reproduce <strong>the</strong> spatial and temporal distributi<strong>on</strong> of TPM isclearly visible from Fig. 6. A north-west transport of smokehaze dominated in September 1997. Compared to TOMS AI<strong>the</strong> intensity of <strong>the</strong> smoke haze originating from Irian Jaya isrelatively low. These differences in modelled and observedsmoke haze distributi<strong>on</strong> can result from <strong>the</strong> fact that TOMSFigure 5.

The <strong>Berlin</strong> 2 <strong>Open</strong> <strong>Access</strong> C<strong>on</strong>-ferencetook place May 12-13, 2004 at CERN. Its aim was to have statusreports by <strong>the</strong> Signatories and to prepare <strong>the</strong> “Road Map”for future developments and acti<strong>on</strong>s. In a special Cerenomyfollowed by a Press C<strong>on</strong>ference <strong>the</strong> <strong>Berlin</strong> Declarati<strong>on</strong> wassigned by <strong>the</strong> CERN Director General thus making CERN aSignatory as well.Most of <strong>the</strong> Singatories were represented and gave briefstatus reports. Representing EGU I reported <strong>on</strong> <strong>the</strong> EGU publicati<strong>on</strong>strategies and efforts with new e-based open accessjournals. It was quite interesting to note that, while o<strong>the</strong>r organizati<strong>on</strong>sare still in <strong>the</strong> planning stages, EGU can reportthat open access is already achieved in <strong>the</strong> whole array ofEGU publicati<strong>on</strong>s. Accordingly, my EGU report was receivedwith high attenti<strong>on</strong> and applauded as an example of where OAshould go. The EGU strategy has not <strong>on</strong>ly shown that OA ispossible, it has moreover dem<strong>on</strong>strated already that OA is superiorto c<strong>on</strong>venti<strong>on</strong>al publicati<strong>on</strong> systems.The Road Map document clearly states that OA is <strong>the</strong> replacementfor <strong>the</strong> c<strong>on</strong>venti<strong>on</strong>al schol-arly communicati<strong>on</strong> paradigmand not its sec<strong>on</strong>d class counterpart. While <strong>the</strong> <strong>Berlin</strong>Declara-ti<strong>on</strong> is <strong>the</strong> visi<strong>on</strong>, <strong>the</strong> roadmap describes first stepstowards OA implementati<strong>on</strong>: Educati<strong>on</strong> and Awareness, signatoriesencourage learned societies to support OA, createawareness at <strong>the</strong> leadership level that OA is no sec<strong>on</strong>d classdisseminati<strong>on</strong>, favor OA proactively by fund-ing incentives andmake it transparent that OA is also beneficial for evaluati<strong>on</strong>processes <strong>on</strong> individual and instituti<strong>on</strong>al levels. The signatoriesaddress in a coordinated way <strong>the</strong> legal framework of OA,for sustainable technical infrastructure facilitating retrieval ofOA material, and address business models for open access.It is planned that <strong>the</strong> signatories report <strong>on</strong> implementati<strong>on</strong>and updating of <strong>the</strong> roadmap in a series of meetings. Throughout<strong>the</strong> coming years, <strong>the</strong>se are planned to be organized every6 m<strong>on</strong>ths by <strong>the</strong> “drivers group” MPG, CNRS, CERN ando<strong>the</strong>rs. The Roadmap document is accessible <strong>on</strong> <strong>the</strong> Internetvia www.zim.mpg.de/openaccess-cern/program_prelim.html.(The <strong>Berlin</strong> Declarati<strong>on</strong> and its signatories can be foundat The Eggs, issue 5, http://www.<strong>the</strong>-eggs.org/news.php?typeid=0&id=120)EGU’s Atmospheric Chemistry and Physics (ACP) <strong>Open</strong> <strong>Access</strong>journal has been a great successby ACP Executive Editors U.

The earth’s protective oz<strong>on</strong>e layerstill remains vulnerableIOC Secretary Christos Zerefos reports from <strong>the</strong> last QOSAs we reposrted in <strong>the</strong> previous issue, <strong>the</strong> 20th Quadrennial Oz<strong>on</strong>e Symposium, coinciding with <strong>the</strong> 20th anniversaryfrom <strong>the</strong> detecti<strong>on</strong> of <strong>the</strong> Antarctic oz<strong>on</strong>e hole, was held in Kos, Greece, 1-8 June 2004. Christos S.Zerefos, host of <strong>the</strong> meeting and Secretary of <strong>the</strong> Internati<strong>on</strong>al Oz<strong>on</strong>e Commissi<strong>on</strong>, presents a briefing of <strong>the</strong>Symposium results.The twentieth Quadrennial Symposium<strong>on</strong> Atmospheric Oz<strong>on</strong>e coincided with <strong>the</strong> 20th anniversaryof <strong>the</strong> discovery of <strong>the</strong> springtime Antarctic oz<strong>on</strong>e hole.It also marked two decades of intensified atmospheric m<strong>on</strong>itoringglobally and basic research in atmospheric chemistry andphysics. The progress in our understanding of <strong>the</strong> impact ofhuman activities <strong>on</strong> <strong>the</strong> chemistry and physics of <strong>the</strong> globalstratosphere since <strong>the</strong> previous Quadrennial Oz<strong>on</strong>e Symposiumwas presented am<strong>on</strong>g <strong>the</strong> 690 research papers at <strong>the</strong>XX Quadrennial Oz<strong>on</strong>e Symposium, held in Kos, Greece, 1-8June 2004 and attended by 450 scientists from 60 countries.The papers presented and <strong>the</strong> proceedings of <strong>the</strong> Symposiumcan be found at www.QOS2004.gr.Am<strong>on</strong>g <strong>the</strong> important topics discussed at <strong>the</strong> Symposiumwere recent research <strong>on</strong> possible oz<strong>on</strong>e recovery, results froman expanded network of satellites and ground-based stati<strong>on</strong>s,oz<strong>on</strong>e-climate interacti<strong>on</strong>s, modeling and chemistry, resultsfrom m<strong>on</strong>itoring of <strong>the</strong> global compositi<strong>on</strong> of <strong>the</strong> tropospherefrom satellites and measurements of UV-B solar radiati<strong>on</strong>reaching ground level am<strong>on</strong>g o<strong>the</strong>rs.Evidence was presented that oz<strong>on</strong>e in <strong>the</strong> past few yearsis a little higher than we expect from earlier projecti<strong>on</strong>s based<strong>on</strong> sensitivity of oz<strong>on</strong>e to influences of aerosols, halogen compoundsand <strong>the</strong> solar cycle. There may be <strong>the</strong> beginning of arecovery in <strong>the</strong> data, an issue that it was shown to be complicatedby a number of factors am<strong>on</strong>g which prominent role isplayed by changes in meteorology, greenhouse gases and in<strong>the</strong> radiati<strong>on</strong> balance, not excluding <strong>the</strong> observed recovery of<strong>the</strong> oz<strong>on</strong>e layer from its perturbati<strong>on</strong> by <strong>the</strong> Pinatubo volcanicerupti<strong>on</strong> in <strong>the</strong> early 90s. The evaluati<strong>on</strong> of future oz<strong>on</strong>e recoveryin a changing climate and <strong>the</strong> effect of oz<strong>on</strong>e <strong>on</strong> thatclimate has shown <strong>the</strong> importance of feedback mechanismsand water vapour c<strong>on</strong>tent in a warmer planet.The need of <strong>the</strong> c<strong>on</strong>tinuati<strong>on</strong> of well-calibrated instrumentsand measurements was extensively discussed and emphasiswas given to <strong>the</strong> use of satellite and ground-based data (exampleNDSC and <strong>the</strong> Global Oz<strong>on</strong>e Observing System) to evaluatemodels and oz<strong>on</strong>e loss and its expected recovery.Numerous chemistry/climate models were presented at <strong>the</strong>c<strong>on</strong>ference. They addressed <strong>the</strong> problem of how changes in<strong>the</strong> meteorology or climate interact with changes in <strong>the</strong> chemistryof oz<strong>on</strong>e. One problem is how changes in meteorologyover <strong>the</strong> last 25 years may have c<strong>on</strong>tributed to observed oz<strong>on</strong>echanges and feedback mechanisms. Models can <strong>the</strong>n be usedto extrapolate that knowledge to what may happen in <strong>the</strong> futurewith <strong>the</strong> expected increase in methane, nitrous oxide, andcarb<strong>on</strong> dioxide.Significant new work that combines satellite and in situ observati<strong>on</strong>swith model calculati<strong>on</strong>s was presented at <strong>the</strong> Symposiumproviding an insight into <strong>the</strong> budget of oxides of nitrogenand a range of halogen species, which are indispensableto our understanding of <strong>the</strong> global carb<strong>on</strong> and hydrological cycles.Water vapour presents a particularly important challenge.Satellite data, shown at <strong>the</strong> meeting, are not c<strong>on</strong>sistent in trendwith previous ground-based data. Understanding <strong>the</strong> feedbackmechanisms between water vapour c<strong>on</strong>tent, oz<strong>on</strong>e, and polarstratospheric clouds is critical to <strong>the</strong> evaluati<strong>on</strong> of predicti<strong>on</strong>sof oz<strong>on</strong>e in a future warmer global atmosphere.Significant progress was made in m<strong>on</strong>itoring <strong>the</strong> troposphericoz<strong>on</strong>e budget with <strong>the</strong> development of new observati<strong>on</strong>altechniques from satellites, combined with models of <strong>the</strong>tropospheric compositi<strong>on</strong>. It turns out that <strong>the</strong> key factors influencing<strong>the</strong> tropospheric oz<strong>on</strong>e budget (precursors, l<strong>on</strong>g-rangetransport in <strong>the</strong> troposphere and intrusi<strong>on</strong>s from <strong>the</strong> stratosphere)make <strong>the</strong> determinati<strong>on</strong> and attributi<strong>on</strong> of troposphericoz<strong>on</strong>e trends difficult.L<strong>on</strong>g-range transport of tropospheric polluti<strong>on</strong> and itscoupling to climate was targeted in a number of studies usingclimate/chemistry models. O<strong>the</strong>r studies have shown <strong>the</strong>importance of l<strong>on</strong>g-range transport of pollutants to maintainregi<strong>on</strong>ally high back ground levels of tropospheric oz<strong>on</strong>e. Forexample, NASA’s satellites and ballo<strong>on</strong>s reveal that seas<strong>on</strong>alepisodes of high oz<strong>on</strong>e over south Atlantic begin with polluti<strong>on</strong>sources originating thousands of miles away.Future UV-B levels for 2000-2019 are predicted to decreasefor all seas<strong>on</strong>s but <strong>the</strong> trends are typically not statistically significant,except during spring over both hemispheres. UV-Btrends are mainly caused by <strong>the</strong> total oz<strong>on</strong>e trends because in<strong>the</strong> future cloud changes are predicted to be small in <strong>the</strong> coupledchemistry climate model used in <strong>the</strong>se results. N<strong>on</strong>e<strong>the</strong>less,<strong>the</strong>re is a regi<strong>on</strong> over Western Europe which is predictedto show an increase in UV-B due primarily to a decrease inTHE EGGS 19


cloudiness. The complexity of interference of cloud and o<strong>the</strong>rphysical parameters in influencing UV-B level at ground levelwas targeted in several papers.In summary, after a close look at <strong>the</strong> individual oral andposter presentati<strong>on</strong>s of <strong>the</strong> Symposium, <strong>the</strong> main c<strong>on</strong>clusi<strong>on</strong> isthat <strong>the</strong> detecti<strong>on</strong> of oz<strong>on</strong>e recovery still requires patience. Wehave still a l<strong>on</strong>g way to go to understand <strong>the</strong> complex systemof interacti<strong>on</strong>s between oz<strong>on</strong>e and a globally changing envir<strong>on</strong>mentand <strong>the</strong> best tools we have at present are <strong>the</strong> c<strong>on</strong>tinuati<strong>on</strong>of global quality observati<strong>on</strong>s both from ground and fromspace. UV-B levels in <strong>the</strong> coming decade or so are predictedto decrease for all seas<strong>on</strong>s except during spring over high latitudesof both hemispheres.Acknowledgements. - The author is indebted to P.J.

Schlesinger (Volume Ed.)Published by: Elsevier Pergam<strong>on</strong>ISBN: 0-08-043751-6 (Set)YEAR : 2004EDITION : 1stPRICE : 3,860.00 €In <strong>the</strong>ir forward, <strong>the</strong> executiveeditors of <strong>the</strong> Treatise <strong>on</strong> Geochemistry,H.D. Holland and K.K. Turekian recallthat <strong>the</strong> first issue of <strong>the</strong> journal devotedto this scientific activity, Geochemicaand Cosmochimica Acta, appeared <strong>on</strong>lyin June 1950. Since <strong>the</strong>n, <strong>the</strong> expansi<strong>on</strong>of geochemistry has been truly dramaticand <strong>the</strong> publicati<strong>on</strong> of a reas<strong>on</strong>ably comprehensiveand integrated summary ofour recent knowledge in this field wastimely. They <strong>the</strong>refore subdivided geochemistryinto nine parts, and each <strong>on</strong>ewas assigned a volume and an editor:Volume 1. Meteorites, Comets, andPlanets _ Andrew M. DavisVolume 2. The Mantle and Core _Richard W. Carls<strong>on</strong>Volume 3. The Crust _ Roberta L.RudnickVolume 4. The Atmosphere _ RalphF. KeelingVolume 5.

Sediments, Diagenesis,and Sedimentary Rocks _ Fred T. MackenzieVolume 8. Biogeochemistry _ WilliamH. SchlesingerVolume 9. Envir<strong>on</strong>mental Geochemistry_ Barbara Sherwood LollarVolume 10. IndexesVolume 10 c<strong>on</strong>tains a detailed indexand tables. The c<strong>on</strong>tent of each volumecan be found <strong>on</strong> <strong>the</strong> web: http://www.treatise<strong>on</strong>geochemistry.comThe producti<strong>on</strong> of this Treatise representsa tremendous task and a criticalresp<strong>on</strong>sibility because it is supposed togive to <strong>the</strong> users a syn<strong>the</strong>tic and upto-datestate of <strong>the</strong> art in <strong>the</strong> field. Thevolume 8 is of special interest for <strong>the</strong>reader of this newsletter. Under <strong>the</strong> titleof Biogeochemistry, <strong>the</strong> volume editorWilliam H. Schlesinger has collected 14chapters devoted to <strong>the</strong> origin and <strong>the</strong>impact of life <strong>on</strong> <strong>the</strong> geochemistry of <strong>the</strong>Earth’s surface.Volume 8 begins with an attractivec<strong>on</strong>tributi<strong>on</strong> of E.G. Nisbet and M.R.Fowler <strong>on</strong> “The Early History of Life”.It describes <strong>the</strong> primitive envir<strong>on</strong>ment<strong>on</strong> earth and looks at <strong>the</strong> physical andchemical c<strong>on</strong>straints favorable to <strong>the</strong>early setting and development of life <strong>on</strong>earth. The next chapter by K.H. Nels<strong>on</strong>and R. Rye develops <strong>the</strong> “Evoluti<strong>on</strong> ofMetabolism” and is complementary to<strong>the</strong> first <strong>on</strong>e. After a survey of <strong>the</strong> metabolicmechanisms and <strong>the</strong> inorganiccomp<strong>on</strong>ents involved, it shows how <strong>the</strong>evoluti<strong>on</strong> of metabolism can be traced,especially by using <strong>the</strong> isotopic fracti<strong>on</strong>ati<strong>on</strong>.The third chapter by J.J. Brocks andR.E. Summ<strong>on</strong>s <strong>on</strong> “Sedimentary Hydrocarb<strong>on</strong>s,Biomarkers for Early Life”,gives a nice example of how <strong>the</strong> use offossil biomarkers can help to rec<strong>on</strong>structancient biospheres for <strong>the</strong> domains oflife (Bacteria, Archeae and Eukarya).It is followed by a relatively l<strong>on</strong>g chapterdealing with Biomineralizati<strong>on</strong> byH.C.W. Skinner and A.H.Jahren. Aftera brief descripti<strong>on</strong> of <strong>the</strong> most comm<strong>on</strong>biominerals, including carb<strong>on</strong>ates, silica,phosphates, sulfur and ir<strong>on</strong> oxides,<strong>the</strong> authors describe <strong>the</strong> mineralizati<strong>on</strong>process in a large variety of organisms,from bacteria to man. There is howeverlittle informati<strong>on</strong> <strong>on</strong> <strong>the</strong> biomineralizati<strong>on</strong>mechanism and <strong>on</strong> <strong>the</strong> biochemicalrole of <strong>the</strong> producti<strong>on</strong> of hard tissues.The next two chapters are devoted to<strong>the</strong> “Biogeochemistry of Primary Producti<strong>on</strong>”respectively in <strong>the</strong> sea by P.G.Falkowski and in terrestrial ecosystemsby F.S.Chapin III and V.T. Eviner. Thenumber of pages devoted to this fundamentalprocess, which sustains all lifeand is resp<strong>on</strong>sible for <strong>the</strong> occurrenceof oxic c<strong>on</strong>diti<strong>on</strong>s at <strong>the</strong> earth surface,is surprisingly limited. The chapter <strong>on</strong><strong>the</strong> photosyn<strong>the</strong>tic activity in <strong>the</strong> marinesystem in particular is ra<strong>the</strong>r c<strong>on</strong>densed.A large part is devoted to <strong>the</strong>use of remote sensing to evaluate primaryproducti<strong>on</strong> and <strong>the</strong> fate of <strong>the</strong> detritalorganic matter. The influence ofnutrients <strong>on</strong> primary producti<strong>on</strong> is <strong>on</strong>lysuperficially discussed. The last part isdevoted to ir<strong>on</strong> limitati<strong>on</strong>. The chapter<strong>on</strong> <strong>the</strong> “Biogeochemistry of TerrestrialProducti<strong>on</strong>” is much more attractive. Itcovers a descripti<strong>on</strong> of <strong>the</strong> mechanismby which plants minimize <strong>the</strong> c<strong>on</strong>straintsof primary producti<strong>on</strong> by balancing <strong>the</strong>limitati<strong>on</strong>s of water CO2 , light and moreespecially nutrients. The authors showhow plants, as individuals or communities,can maintain producti<strong>on</strong> by makingadjustments through shift in <strong>the</strong>ir physiologicaltraits.A larger part of volume 8 of <strong>the</strong> Treatiseis devoted to <strong>the</strong> decompositi<strong>on</strong> oforganic matter. Chapter 7 entitled “Biogeochemistryof Decompositi<strong>on</strong> and DetritalProcessing” by J. Sanderman andR. Amunds<strong>on</strong> discuss successively <strong>the</strong>c<strong>on</strong>current or sequential process leadingto <strong>the</strong> decompositi<strong>on</strong> of terrestrialorganic matter: comminuti<strong>on</strong> or fragmentati<strong>on</strong>,leaching of water solublecompounds and microbial metabolism.A large secti<strong>on</strong> is devoted to <strong>the</strong> factorc<strong>on</strong>trolling <strong>the</strong>se processes in litter andsoil. The next chapter treats more precisely<strong>the</strong> degradati<strong>on</strong> of organic matterin <strong>the</strong> absence of oxygen: “AnaerobicMetabolism: Linkage to Trace Gasesand Aerobic Processes” by J.P. Meg<strong>on</strong>igal,M.E. Minas and P.T. Visscher. TheTHE EGGS 22


chapter starts with a brief discussi<strong>on</strong> ofCO2 assimilati<strong>on</strong> by autotrophs, decompositi<strong>on</strong>of polymers and fermentati<strong>on</strong>.Methanogenesis and methane oxidati<strong>on</strong>receives more attenti<strong>on</strong>. It is followed bya review of <strong>the</strong> various inorganic electr<strong>on</strong>acceptors in <strong>the</strong> order of decreasingenergy yield: nitrogen, manganese, ir<strong>on</strong>and sulfur.The next two chapters are devotedto <strong>the</strong> history of <strong>the</strong> carb<strong>on</strong> cycle <strong>on</strong> aglobal scale. The “Geological History of<strong>the</strong> Carb<strong>on</strong> Cycle” is treated by E.T. Sundquistand K. Visser. This chapter (8.9)describes and quantifies <strong>the</strong> natural processesand fluxes affecting <strong>the</strong> carb<strong>on</strong>cycle at <strong>the</strong> earth surface, which may beobserved in <strong>the</strong> geological record. Emphasisis put <strong>on</strong> <strong>the</strong> Quaternary periodfor which <strong>the</strong> geological record is farbetter than that available for earlier geologicperiods. It dem<strong>on</strong>strates <strong>the</strong> closeinteracti<strong>on</strong>s between <strong>the</strong> atmosphere,<strong>the</strong> biosphere and <strong>the</strong> hydrosphere duringglacial and interglacial variati<strong>on</strong>.The chapter ends with a short discussi<strong>on</strong>of <strong>the</strong> more substantial crustalexchange processes that have beenidentified as causes for gradual geologiccarb<strong>on</strong>-cycle changes during <strong>the</strong> phanerozoic.The “C<strong>on</strong>temporary Carb<strong>on</strong> Cycle”by R.A. Hought<strong>on</strong> c<strong>on</strong>stitutes <strong>the</strong> chapter8.10. It is a classical report of <strong>the</strong> majorreservoirs of carb<strong>on</strong> <strong>on</strong> <strong>the</strong> earth surfaceand of <strong>the</strong> fluxes, natural or anthropogenic,observed presently. Changesin <strong>the</strong> stocks and fluxes of carb<strong>on</strong> asa result of human activities as well <strong>the</strong>mechanisms thought to be resp<strong>on</strong>siblefor <strong>the</strong> current sinks of carb<strong>on</strong> are treatedmore specifically. The next chapter(8.11) about “The Global Oxygen Cycle”by S.T.Petsch is complementary to <strong>the</strong>previous <strong>on</strong>e, covering <strong>the</strong> distributi<strong>on</strong>of O2 in <strong>the</strong> atmosphere from <strong>the</strong> Archeanto <strong>the</strong> Phenerozoic. Also closelylinked to <strong>the</strong> carb<strong>on</strong> cycle, <strong>the</strong> two nextchapters (8.12 and 8.13) are devotedrespectively to <strong>the</strong> “Global Nitrogen Cycle”by J.N. Galloway and “The GlobalPhosphorus Cycle” by K.C. Ruttenberg.Both chapters discuss not <strong>on</strong>ly detailedbiogeochemical cycles of <strong>the</strong>se essentialnutrients but also emphasize variousanthropogenic perturbati<strong>on</strong> of <strong>the</strong>irnatural cycle. The chapter <strong>on</strong> Nitrogengives very detailed budgets and fluxesof <strong>the</strong> numerous N species within andbetween <strong>the</strong> atmospheric, terrestrial andmarine system. It is unfortunately c<strong>on</strong>densedwithin 26 pages which is shortfor such an important subject. By comparis<strong>on</strong>,<strong>the</strong> next 58 pages are devotedto <strong>the</strong> phosphorus cycle, with less detaileddata <strong>on</strong> <strong>the</strong> fluxes but with ra<strong>the</strong>rdetailed descripti<strong>on</strong>s of <strong>the</strong> mechanismsresp<strong>on</strong>sible for <strong>the</strong> P cycling mainly in<strong>the</strong> aquatic systems. Finally, <strong>the</strong> lastchapter written by P. Brimblecombe describes“The global Sulfur Cycle”. Theauthor has realized a nice equilibriumbetween <strong>the</strong> numerous biotic and abioticprocesses governing <strong>the</strong> cycle ofthis element present in a large varietyof gaseous, liquid and solid compounds.He also shows <strong>the</strong> large perturbati<strong>on</strong>s of<strong>the</strong> natural cycle related to human activities.Most of <strong>the</strong> chapters in this volumeare easy and agreeable to read. Theyavoid l<strong>on</strong>g historical descripti<strong>on</strong> of <strong>the</strong>evoluti<strong>on</strong> of <strong>the</strong> subject and are generallywell focused <strong>on</strong> <strong>the</strong> latest developmentsof our knowledge. This is wellreflected in <strong>the</strong> references cited whichare mainly covering <strong>the</strong> last ten years(except for chapters 3 and 4). The presentati<strong>on</strong>is usually pleasant but sometables and figures require a magnifyinglens to be readable. The Treatise<strong>on</strong> Geochemistry is without any doubta very useful reference book for a largescientific community and especially forstudents and teachers.Only <strong>the</strong> whole set of 10 volumesis available at a price of 4.825 EURin Europe and Japan and 4.595 US$world-wide except Europe and Japan.At <strong>the</strong> current value of <strong>the</strong> EURO (1.24US$) this represents an equivalent priceequal to 5.983 US$ in Europe and Japan,thus 30% more expensive than in<strong>the</strong> US. This difference is unacceptable,especially for such heavy investment.Prof. R.

Thetitle of <strong>the</strong> volume is not very appealingto my taste, since I would ra<strong>the</strong>r preferPolluti<strong>on</strong> Geochemistry instead, whichmore accurately reflects <strong>the</strong> c<strong>on</strong>tents of<strong>the</strong> volume. Surely, “Envir<strong>on</strong>mental” wasnot coined by <strong>the</strong> authors or <strong>the</strong> VolumeEditor, but never<strong>the</strong>less I bel<strong>on</strong>g to <strong>the</strong>sepeople who are somewhat annoyed by<strong>the</strong> overuse of “envir<strong>on</strong>mental” nowadays.Moving bey<strong>on</strong>d <strong>the</strong> title, <strong>the</strong> volumepresents an interesting and quite broadcollecti<strong>on</strong> of chapters that were selected,THE EGGS 23


according to Barbara S. Lollar who edited<strong>the</strong> volume, following to two guidingprinciples: Firstly, focusing <strong>on</strong> geochemicalimpacts <strong>on</strong> <strong>the</strong> human health and<strong>the</strong> health of <strong>the</strong> envir<strong>on</strong>ment. Sec<strong>on</strong>dly,focusing <strong>on</strong> impacts at <strong>the</strong> local and <strong>the</strong>regi<strong>on</strong>al ra<strong>the</strong>r than <strong>the</strong> global scale. Insome of <strong>the</strong> chapters, both <strong>the</strong> impactof natural geochemical processes andof anthropogenic perturbati<strong>on</strong>s was addressed,while <strong>on</strong> o<strong>the</strong>rs <strong>the</strong>re is specificfocus <strong>on</strong> anthropogenic perturbati<strong>on</strong>s.The scope of <strong>the</strong> volume is so broad thatI am surely not able to review all chapterssince some of <strong>the</strong>m fall quite far from myfields of interest.The book has 16 chapters, a volumesubject Index, 630 pages, many Tablesand Figures. The latter are mostly B&W,while <strong>the</strong>re are about 10 color <strong>on</strong>es. Areference list at <strong>the</strong> end of each chapterfacilitates <strong>the</strong> reader that wants to lookdeeper in <strong>the</strong> aspects treated in <strong>the</strong> chapter;many references are very recent andgo until 2002. 70% of <strong>the</strong> 38 c<strong>on</strong>tributorscome from <strong>the</strong> US and Canada – an additi<strong>on</strong>al15% comes from <strong>the</strong> UK. Thisfact is not in favor of <strong>the</strong> volume, sinceaspects of relevant research that arepursued more actively in o<strong>the</strong>r parts ofEurope and <strong>the</strong> rest of <strong>the</strong> world are notpresented adequately.The first chapter is <strong>on</strong> risk, toxicityand exposure assessment for groundwaterand air c<strong>on</strong>taminati<strong>on</strong>. It goes fromdefiniti<strong>on</strong>s of risk through regulatory andpolicy aspects and processes, throughexposure and toxicity assessment, riskcharacterizati<strong>on</strong> and uncertainties to riskmanagement and communicati<strong>on</strong>. Thefollowing three chapters deal with metalsin <strong>the</strong> envir<strong>on</strong>ment – selenium, arsenic,heavy metals and mercury, treating tosome extend analytical methods, abundance,forms and biogeochemical pathwaysand emissi<strong>on</strong>s. Chapter 5 dealsquite comprehensively with acid minedrainage: mineralogy, sulfide oxidati<strong>on</strong>,neutralizati<strong>on</strong>, sec<strong>on</strong>dary minerals, drainage,bioaccumulati<strong>on</strong> and toxicity, remediati<strong>on</strong>and preventi<strong>on</strong>.Chapter 6 deals, in 58 pages, withradioactive c<strong>on</strong>taminati<strong>on</strong>. Chapter 7,which I found quite interesting, is named“The medical geochemistry of dusts, soilsand o<strong>the</strong>r earth materials”. This chapterdeals with <strong>the</strong> linkages of earth materialsto human health: <strong>the</strong> different earthmaterials, <strong>the</strong>ir health effects, exposureroutes, assessment methods, chemicalc<strong>on</strong>diti<strong>on</strong>s in <strong>the</strong> human body parts, bioreactivityare all treated briefly; <strong>the</strong> treatmentis augmented with five and a halfreference pages.The next three chapters deal wi<strong>the</strong>utrophicati<strong>on</strong>, salinisati<strong>on</strong>, acidificati<strong>on</strong>and acid rain. The eutrophicati<strong>on</strong> chapterby E.E. Prepas and T. Charette fromCanada, in effect presents briefly somecase studies from Canadian Lakes; <strong>the</strong>o<strong>the</strong>r two chapters are, in my opini<strong>on</strong>,more broad.Chapter 11 deals with troposphericoz<strong>on</strong>e and particulates, a field where I feelmore c<strong>on</strong>fident to comment. S. Sillman isnot a stranger in <strong>the</strong> field and he presentsa nice overview, although limited somewhatto addressing US approaches andproblems as well as <strong>the</strong> author’s maininterests. I would like to see photosmogproblems in Asia, Africa and Europe alsotreated, and a bit more of <strong>the</strong> regulatoryaspects of our approaches to air quality.The figures are informative, clear and understandableeven to <strong>the</strong> undergraduate.Chapter 12 is <strong>on</strong> volatile fuel hydrocarb<strong>on</strong>sand MTBE. The next Chapteris <strong>on</strong> high molecular weight petrogenicand pyrogenic hydrocarb<strong>on</strong>s in aquaticenvir<strong>on</strong>ments. Chapters 14 and 15 dealwith halogenated hydrocarb<strong>on</strong>s andpesticides, while <strong>the</strong> last Chapter is <strong>on</strong>groundwater geochemistry of waste disposalfacilities.The volume is excellently edited withreally very few misspelling errors and <strong>the</strong>quality of <strong>the</strong> figures is also great. In brief,<strong>the</strong> volume is very appealing. But again,as I have argued in <strong>the</strong> last issue when Iintroduced this set, it can be bought <strong>on</strong>lyas a set for a very high price; I would stillfind <strong>the</strong> price high if it was possible to buyindividual volumes for <strong>the</strong> corresp<strong>on</strong>dingfracti<strong>on</strong> of <strong>the</strong> price. This volume, as wellas o<strong>the</strong>r volumes of this set, surely hasstudents as a target group, but again it isout of <strong>the</strong>ir reach. Only university librariescan afford <strong>the</strong> set, and in <strong>the</strong> presentsituati<strong>on</strong> certainly <strong>on</strong>ly some libraries in<strong>the</strong> most affluent countries. It is a pity toproduce such an excellent work and <strong>the</strong>nrestrict its access to most people but aprivileged few. My view is that in our eraof budgetary c<strong>on</strong>strains such a businessmodel is no l<strong>on</strong>ger affordable. This situati<strong>on</strong>has led to <strong>the</strong> open access initiativesin <strong>the</strong> field of scientific journals and willso<strong>on</strong> lead to a similar initiative in <strong>the</strong> fieldof books, especially <strong>the</strong> review or treatise<strong>on</strong>es. You can have a look alreadyat <strong>the</strong> “Live Reviews” – review articlesthat are regularly updated by <strong>the</strong> authors– principle that was recently initiated byMPI for Solar System Research with <strong>the</strong>launch of a new <strong>on</strong>line journal for SolarPhysics (this issue, http://www.<strong>the</strong>-eggs.org/news.php?id=180&typeid=0). It isc<strong>on</strong>ceivable that after some time, whenenough articles are published, <strong>the</strong>sefreely accessed reviews will present avery comprehensive, treatise-like set ofarticles. It is also c<strong>on</strong>ceivable that similarinitiatives in o<strong>the</strong>r fields will sprout upso<strong>on</strong>, if such excellent works by membersof <strong>the</strong> academic community as <strong>the</strong>present Treatise <strong>on</strong> Geochemistry aremarketed in a similar way.Kostas KourtidisDept. of Envir<strong>on</strong>mental EngineeringSchool of EngineeringDemokritus University of ThraceXanthi, Greecekourtidi@env.duth.grTHE EGGS 24


A valuable learning tool for advanced studentsAn Introducti<strong>on</strong> to Seismology, Earthquakes,and Earth StructureSeth Stein and Michael Wysessi<strong>on</strong>Published by: Blackwell PublishingISBN: 0-86542-078-5YEAR : 2003EDITION : 1#PAGES : 498PRICE : 34.95 €Writing a modern introductorybook to seismologyis not an easy task. This is due to thatunderstanding <strong>the</strong> seismological methodsas well as <strong>the</strong> physical earthquakeprocesses is very much dependent <strong>on</strong><strong>the</strong> knowledge about <strong>the</strong> internal Earth’sstructure. In fact, most of our knowledgeabout <strong>the</strong> physics of <strong>the</strong> Earth’s interiorcomes from <strong>the</strong> study of <strong>the</strong> seismicwaves. C<strong>on</strong>versely, any new progress wemake in exploring <strong>the</strong> interior of our planetc<strong>on</strong>stitutes a fur<strong>the</strong>r step in understandingbetter <strong>the</strong> earthquake phenomena.In this sense <strong>the</strong> book of S. Steinand M. Wysessi<strong>on</strong> is a really modernpublicati<strong>on</strong> by <strong>the</strong> means that it is centeredaround <strong>the</strong> two mutually dependentfundamental aspects of seismology andEarth structure. The book’s introducti<strong>on</strong>is a small surprise since it does not introduce<strong>the</strong> reader to some general physicalproperties of <strong>the</strong> planet and <strong>the</strong> similarbut it is mostly devoted to <strong>the</strong> societalvalue of seismology, like <strong>the</strong> seismic hazardand engineering seismology aspects,earthquake associated hazardous phenomena,like tsunamis, landslides andsoil liquefacti<strong>on</strong>, and nuclear m<strong>on</strong>itoringand treaty verificati<strong>on</strong>. This directly signifiesthat seismology is an applied scienceof great importance for <strong>the</strong> humanity.Apart from its Introducti<strong>on</strong> <strong>the</strong> bookis structured around a set of ano<strong>the</strong>r sixChapters and <strong>on</strong>e Appendix. Chapter 2deals with basic seismological <strong>the</strong>orywhich, after some fundamentals <strong>on</strong> stressand strain, a “must” for every introductoryseismological book, proceeds with a detailedenough analysis of <strong>the</strong> propertiesand optical laws of seismic waves, <strong>the</strong>irdispersi<strong>on</strong> and <strong>the</strong> normal modes of <strong>the</strong>Earth.Chapter 3 is devoted to <strong>the</strong> closely interrelatedtopics of seismology and Earthstructure. The crustal, mantle and corestructures are derived <strong>on</strong> a physicallycomprenhesive way from methods of <strong>the</strong>refracti<strong>on</strong> and reflecti<strong>on</strong> seismology, <strong>the</strong>propagati<strong>on</strong> of seismic waves in a sphericalEarth and <strong>the</strong> travel times of bodywaves. Special attenti<strong>on</strong> is given to <strong>the</strong>anisotropy in different scales within <strong>the</strong>Earth, to <strong>the</strong> attenuati<strong>on</strong> of seismic wavesand <strong>the</strong>ir significance for understanding<strong>the</strong> Earth’s structure. The compositi<strong>on</strong> of<strong>the</strong> mantle and <strong>the</strong> core is fur<strong>the</strong>r examined<strong>on</strong> <strong>the</strong> basis of density, <strong>the</strong>rmal andmineralogical models. Pers<strong>on</strong>ally I wouldprefer to see a more detailed presentati<strong>on</strong>of <strong>the</strong>se models which are of increasinguse in <strong>the</strong> last years for an alternativec<strong>on</strong>trol of <strong>the</strong> seismological models of <strong>the</strong>Earth’s structure.Chapter 4 examines earthquakes, inparticular several aspects related to <strong>the</strong>seismic source and its properties from <strong>the</strong>focal mechanisms, waveform modelingand moment tensors to <strong>the</strong> earthquakegeodesy, source parameters and earthquakestatistics. Of particular interest andof adequate extensi<strong>on</strong> is <strong>the</strong> analysis regarding<strong>the</strong> isotropic and CLVD momenttensor decompositi<strong>on</strong>s which are of greatvalue for <strong>the</strong> descripti<strong>on</strong> of double-coupleand n<strong>on</strong>-double-couple seismic sources.The close c<strong>on</strong>necti<strong>on</strong> of <strong>the</strong> seismological<strong>the</strong>ory with <strong>the</strong> plate tect<strong>on</strong>ics isexamined in Chapter 5. Fundamentalsabout plate kinematics, spreading centers,and subducti<strong>on</strong> z<strong>on</strong>es are reviewedand <strong>the</strong> generati<strong>on</strong> of earthquakes al<strong>on</strong>g<strong>the</strong> plate margins as well as in oceanicintraplate and c<strong>on</strong>tinental envir<strong>on</strong>mentsare geodynamically interpreted. Thischapter c<strong>on</strong>cludes with an overview of<strong>the</strong> faulting and deformati<strong>on</strong> processes,like rheology, rock fracture and fricti<strong>on</strong>,ductile flow, strength of <strong>the</strong> lithosphereand regi<strong>on</strong>al deformati<strong>on</strong> and <strong>the</strong>ir role in<strong>the</strong> process of seismogenesis.During <strong>the</strong> last few decades <strong>the</strong> progressmade in <strong>the</strong> digital techniques for recordingearthquakes and analysing seismogramsis tremendous and, <strong>the</strong>refore,<strong>the</strong> title Seismograms as Signals, of <strong>the</strong>Chapter 6 of <strong>the</strong> book, is absolutely justified.Its beginning is devoted to <strong>the</strong> severaltechniques of Fourier analysis, while<strong>the</strong> subsequent secti<strong>on</strong>s describes <strong>the</strong>ma<strong>the</strong>matics of linear systems, <strong>the</strong> discretetime series and transforms, stackingtechniques as well as seismometersand seismological networks.Inversi<strong>on</strong> techniques are am<strong>on</strong>g <strong>the</strong>most effective in solid earth geophysicsand this explains well why Chapter7 deals with inverse problems like locatingearthquakes for homogeneous mediumor complex geometries, travel timetomography and stratificati<strong>on</strong> of Earthstructure.The tuiti<strong>on</strong> comp<strong>on</strong>ent of <strong>the</strong> book isobvious and remarkably str<strong>on</strong>g. In fact,each chapter begins with an outline andTHE EGGS 25


a list of learning objectives and ends withhomework and computer problems. Soluti<strong>on</strong>sto selected odd-numbered problemsare listed in <strong>the</strong> back so that students cantrack <strong>the</strong>ir progress. Moreover, <strong>the</strong> sevenchapters of <strong>the</strong> book are supplementedby an extensive Appendix which c<strong>on</strong>tainsma<strong>the</strong>matical and computati<strong>on</strong>al backgroundlike complex numbers, scalarsand vectors, matrix algebra, vector transformati<strong>on</strong>s,vector calculus, sphericalcoordinates and scientific programming.The l<strong>on</strong>g number of diagrams and o<strong>the</strong>rfigures is an additi<strong>on</strong>al, positive ingredientof <strong>the</strong> book’s c<strong>on</strong>tent. However, picturesfrom <strong>the</strong> macroseismic field are obviouslylacking from chapters where such materialcould be useful, like <strong>the</strong> Chapters 1, 4and 5. This is possibly explained by that<strong>the</strong> book does not cover every topic of<strong>the</strong> earthquake science, like macroseismologyand earthquake geology, but itra<strong>the</strong>r focuses <strong>on</strong> <strong>the</strong> geophysical andmethodological interrelati<strong>on</strong>s betweenseismology and earth structure.There is no doubt that <strong>the</strong> publicati<strong>on</strong>is a valuable learning tool for advancedundergraduate and beginning graduatestudents and a useful reference book not<strong>on</strong>ly for seismologists but also for solidearth scientists in general.Dr. Gerassimos PapadopoulosInstitute of Geodynamics, Nati<strong>on</strong>alObservatory of A<strong>the</strong>nsPO Box 20048, 11810 A<strong>the</strong>ns,Greeceg.papad@egelados.gein.noa.grTHE EGGS 26

Gas transferdepends <strong>on</strong> <strong>the</strong> gas air-water gradient and <strong>the</strong> gas transfervelocity. The air-water gradient is generated by physical,chemical and biological processes acting from daily to climatictime-scales. The gas transfer velocity depends <strong>on</strong> numerouscomplex processes, <strong>the</strong> major <strong>on</strong>e being turbulence in surfacewater and/or air. Wind stress at <strong>the</strong> interface is <strong>the</strong> main turbulencegenerator but at low wind speeds, <strong>the</strong> air-water gastransfer is fur<strong>the</strong>r modulated by presence of surfactants, c<strong>on</strong>vectivecooling, chemical enhancement and water currents.At high wind speeds, waves, bubbles and spray also str<strong>on</strong>glyc<strong>on</strong>tribute to air-water gas transfer. Topics of relevance to <strong>the</strong>Colloquium include: - Laboratory and/or field measurementsof air-water transfer of gas, heat, vapour and particles usingvarious approaches (mass balance of natural, anthropogenicor deliberate tracers and micro-meteorological methods). -Theoretical and/or experimental studies of <strong>the</strong> various aspectsTHE EGGS 30
