SUMMARY:2016 Ocean Sciences Meeting
DESCRIPTION:2016 Ocean Sciences Meeting Dates: 21-26 February 2016Location: New Orleans\, Louisiana\, USA. \nFor more information: http://osm.agu.org/2016/ \nGEOTRACES and GEOTRACES-related Town Halls:  \nTown Hall “Opportunities to Strengthen Your Science (and Proposals) using GEOTRACES Data”  \nThursday\, February 25\, 2016: 6:30 PM – 7:30 PMLocation: Ernest N. Morial Convention Center\, 228-230   \nDescription: GEOTRACES released its first intermediate data product ( IDP2014)\, featuring dissolved trace elements and their isotopes\, during the 2014 Ocean Science meeting. The next data product (IDP2017) will more than double the amount of data and number of variables\, including particulate elements. This town hall will: 1) Inform the community about strategies to access\, download and manipulate data from IDP2014 and provide preliminary information about IDP2017; 2) Seek feedback from users of IDP2014 to improve IDP2017 and make it as user-friendly as possible; and 3) Present the outcome of the first Iron-Model Intercomparison Project (FeMIP)\, in which comparison to GEOTRACES data allowed an unprecedented assessment of model performance.  \n \nTowards a standard\, user-friendly chemical speciation model for seawater and estuarine waters \nMonday\, February 22\, 2016 — 12:45-1:45 pmLocation: Ernest N. Morial Convention Center\, 228-230 \nThere is at present no community-agreed model for calculating speciation – particularly of key trace metals\, the carbonate system\, and including the various definitions of pH – in oceanic and estuarine environments. Consequently\, chemical speciation calculations are often of uncertain accuracy\, and are neither traceable nor repeatable by others. SCOR Working Group 145 aims to (i) develop an internationally agreed speciation model based on the Pitzer equations to address these problems\, and (ii) make this model available through a user-friendly web tool. This Town Hall meeting will present the draft scope of the model and seek comments from potential users. \n GEOTRACES-sessions: \nAtmospheric deposition and ocean biogeochemistry \nMonday\, February 22\, 2016\, 228-230: 8-10 am\, Poster Hall: 4-6 pm \nPrimary Chair: Ana M Aguilar-Islas\, University of Alaska Fairbanks\, Fairbanks\, AK\, United StatesChairs: Clifton S Buck\, Skidaway Institute of Oceanography\, Savannah\, GA\, United States and Meredith Galanter Hastings\, Brown Univ-Geological Sciences\, Providence\, RI\, United States \nSession Description: \nAtmospheric deposition of marine\, lithogenic and anthropogenic aerosols is an important transport pathway for nutrients and contaminants to the surface ocean. Constraining local\, regional and global atmospheric deposition flux estimates and the bioavailability of aerosol-derived elements and compounds is essential for furthering understanding of ocean biogeochemistry. This transport pathway acts as an important chemical bridge between the lithosphere and hydrosphere linking major biogeochemical cycles. Aerosol emission\, transport and deposition processes are\, in part\, a function of global change related to changes in land coverage\, anthropogenic emissions and climate. Hence the study of ocean responses will improve our ability to predict future impacts. The GEOTRACES international program includes objectives related to the atmospheric input of trace elements and isotopes to accomplish its goal. Other programs\, such as SOLAS and CLIVAR\, continue to make significant contributions as well. This session invites contributions from studies of atmospheric deposition in the marine environment\, including observations of atmospheric deposition fluxes\, aerosol composition\, aerosol fractional solubility\, the fate of aerosol-derived compounds and the biological and chemical response to deposition within the surface ocean. Contributions from global and regional scale field observations\, laboratory studies and modeling efforts are welcomed. \nThe role of particles in the cycling of trace elements and their isotopes in the ocean \nTuesday\, February 23\, 2016\, 228-230: 8-10 am\, 2-4 pm\, Poster Hall: 4-6 pm \nPrimary Chair: Hélène Planquette\, LEMAR\, CNRS\, Plouzané\, France Chairs: Phoebe J Lam\, University of California Santa Cruz\, Department of Ocean Sciences\, Santa Cruz\, CA\, United States and Benjamin S. Twining\, Bigelow Lab for Ocean Sciences\, East Boothbay\, ME\, United States \nSession Description: \nA number of trace metals are thought to control marine ecosystem features and biological productivity. While trace elements in the dissolved phase have been the focus of many investigations\, we are still largely ignorant of the large scale distribution of particulate trace elements and their size partitioning and chemical composition. The GEOTRACES program\, which aims to provide a comprehensive view of the distribution of trace elements and their isotopes (TEIs) in the world’s oceans\, is providing new insights on these aspects. Furthermore\, there is a crucial need to understand the exchange mechanisms between particulate and dissolved pools\, including adsorption\, desorption\, aggregation\, precipitation\, biological uptake and remineralization processes. This session seeks to bring together scientists interested in better constraining the role of ocean particles in the biogeochemical cycles of TEIs\, in different oceanic environments\, such as the continental shelves and slopes\, the nepheloid layers\, or the particle-poor regions of the open ocean. We invite abstracts on all aspects of oceanic particulate TEIs\, through experimental\, in situ and modeling approaches. \nTrace Elements and Isotopes at the Interfaces of the Atlantic Ocean \nMonday\, February 22\, 2016\, 228-230: 10:30 am-12:30 pm\, Poster Hall: 4-6 pm \nPrimary Chair: Geraldine Sarthou\, LEMAR UMR 6539 CNRS UBO IRD IFREMER\, IUEM\, Plouzané\, FranceChairs: Edward A Boyle\, Massachusetts Institute of Technology\, Earth Atmospheric and Planetary Sciences\, Cambridge\, MA\, United States\, Gideon Mark Henderson\, University of Oxford\, Earth Sciences\, Oxford\, United Kingdom and Micha J.A. Rijkenberg\, Royal Netherlands Institute for Sea Research\, Den Burg\, Netherlands \nSession Description: \nTrace elements play a crucial role in the ocean. Some are toxic at high concentrations\, others serve as essential micronutrients in the many metabolic processes active in marine organisms. Some trace elements and their isotopes (TEIs) are diagnostic and allow the quantification of specific oceanic mechanisms. Studying the biogeochemical cycles of TEIs is thus necessary to deepen our understanding of carbon and nutrient cycling\, climate change\, ocean ecosystems and environmental contamination. The Atlantic Ocean is one of the primary CO2 sinks of the world ocean and one of the most biologically productive. Recently\, full-depth high resolution measurement campaigns\, especially in the framework of the international GEOTRACES program\, have revolutionized our understanding of the TEI cycling in the Atlantic Ocean. However\, processes occurring at the oceanic interfaces are very complex and need more attention. The aim of this session is to increase our understanding of the exchange of TEIs at the interfaces between the ocean and i) the atmosphere\, ii) the continents (e.g. by rivers and groundwater)\, iii) the marine sediments\, and iv) the ridges. We will particularly encourage contributions dealing with interdisciplinary studies\, with new insights gained by application of state-of-the-art analytical tools and modeling approaches. \nTrace Metal Bioavailability and Metal-Microorganism Interactions  \nThursday\, February 25\, 2016\, 228-230: 8-10 am\, Poster Hall: 4-6 pm \nPrimary Chair: Julia M Gauglitz\, Woods Hole Oceanographic Institution\, Marine Chemistry and Geochemistry\, Woods Hole\, MA\, United StatesChairs: Randelle Bundy\, Woods Hole Oceanographic Institution\, Marine Chemistry and Geochemistry\, Woods Hole\, MA\, United States and Jill N Sutton\, IUEM/UBO\, Technopôle Brest-Iroise\, Place Nicolas Copernic\, Plouzané\, France \nSession Description: \nThe distributions of trace elements in the marine environment are undeniably linked to biological processes. Low concentrations or low bioavailability of trace metals in the water column can lead to micronutrient limitation and stress\, while greater availability may increase biological demand and enhance the growth of microorganisms. Recent advances in high throughput biological techniques\, including “omics”\, as well as high-resolution geochemical data from the GEOTRACES program (www.geotraces.org) has lead to a wealth of new data. However\, meaningful interpretation of these data often still relies on process studies\, incubation-based experimental work\, or the culturing of representative or novel organisms. This session invites contributions on every scale of metal-microorganism interactions\, ranging from small-scale mechanistic work to large-scale biogeochemical cycle studies. We encourage abstracts that investigate trace metal acquisition strategies\, cellular metabolism\, chemical speciation and bioavailability\, and/or studies that link trace metal and biological water column data. Presentations that strive to better understand the biological control exerted on the distribution of trace elements in the marine environment are especially encouraged. \nTrace metal speciation in seawater: measurements\, modelling and impact on marine biogeochemistry \nWednesday\, February 24\, 2016\, 228-230: 8-10 am\, 2-4 pm\, Poster Hall: 4-6 pm \nPrimary Chair: David R Turner\, University of Gothenburg\, Gothenburg\, SwedenChairs: Stan MG van den Berg\, University of Liverpool\, Liverpool\, L69\, United Kingdom\, Sylvia Gertrud Sander\, University of Otago\, Dunedin\, New Zealand\, Kristen N Buck\, University of South Florida Tampa\, Tampa\, FL\, United States\, Rachel Shelley\, LEMAR/UBO\, Brest\, France\, Peter L Morton\, Florida State University\, Department of Earth\, Ocean\, and Atmospheric Science\, Tallahassee\, FL\, United States\, Christian Schlosser\, GEOMAR Helmholtz Centre for Ocean Research Kiel\, Chemical Oceanography\, Kiel\, Germany and Eric P. Achterberg\, GEOMAR Helmholtz Centre for Ocean Research Kiel. \nSession Description: \nGlobal change processes\, in particular ocean acidification\, are changing the chemistry of seawater. The carbon dioxide system and trace metal speciation are expected to be among the chemical components of seawater most strongly affected by global change processes. The distribution and identity of organic metal complexing ligands in the marine system\, and modelling of the chemical speciation using updated parameters\, play an important role in understanding the changes that take place and in projecting future changes. This session builds on two SCOR working groups : WG139 which is focused on organic metal-binding ligands; and WG145 which is focused on modelling metal speciation in seawater. One aspect of metal speciation that is receiving particular attention is the bioavailability of trace metals\, with extensive measurement programmes on the complexation of bioactive trace metals currently under way\, in particular within the GEOTRACES program. This work is producing exciting new field data that will benefit from improved speciation modelling and additional measurements. We invite contributions on the identification\, distribution and provenance of organic ligands in the marine environment\, the modelling of inorganic and organic metal speciation\, and linkages of trace metal speciation with ocean acidification and other factors of climate change. \nGEOTRACES-related sessions descriptions:  \nVariability in Southern Ocean Productivity over Different Timescales \nThursday\, February 25\, 2016\, Poster Hall: 4-6 pmFriday\, February 26\, 2016\, 215-216: 10:30 am-12:30 pm \nPrimary Chair: Alessandro Tagliabue\, University of Liverpool\, Liverpool\, United KingdomChairs: Philip Boyd\, IMAS\, ACE-CRC\, University of Tasmania\, Hobart\, Australia\, Eugene W Domack\, University of South Florida St. Petersburg\, St Petersburg\, FL\, United States and Amy Leventer\, Colgate University\, Geology\, Hamilton\, NY\, United States \nSession Description: \nSouthern Ocean productivity plays an important role in regulating marine resources\, ocean biogeochemistry and the global carbon cycle. Canonically\, variations in iron supply and demand are thought to regulate the variations in phytoplankton productivity. However\, via the actions of ocean physics\, the Southern Ocean also encounters substantial fluctuations across space and time in temperature\, sea ice and glacial ice dynamics and the availability of light and/or macro- and micro-nutrients. How these regulatory factors act individually and in combination to shape the dynamics of biological activity across food webs in different Southern Ocean regions and different timescales is not well understood. This hampers our ability to project with confidence how future environmental change will affect this important ecosystem. In particular we lack an understanding of how variations in the physical and/or biogeochemical environment are underpinned and connected to the broader picture of ecosystem structure\, as well as wider biogeochemical feedbacks. We invite presentations from field\, laboratory\, remote sensing\, modelling and paleo studies that seek to unravel the dynamics of the Southern Ocean marine ecosystem from a seasonal or decadal or millenial scale viewpoint. Efforts to combine insights across disciplines and scales from physics to biogeochemistry to ecosystems are actively encouraged. \n \nGEOTRACES Tutorial: \nT014: What Controls the Distribution of Dissolved Iron in the Ocean? \nTuesday\, February 23\, 2016\, 03:30 PM – 04:00 PMLocation: Ernest N. Morial Convention Center – RO3 \nPrimary Chair: Alessandro Tagliabue\, University of Liverpool\, Liverpool\, L69\, United Kingdom \nSession Description: \nDue to its role as a limiting nutrient in the Southern Ocean\, the role for iron in governing how ocean productivity influences wider biogeochemical cycling and atmospheric carbon dioxide levels is well accepted. Around twenty years ago the first compendium of dissolved iron observations was published\, enabling initial insights into the controls on its cycling and distribution. Today the number of compiled iron observations stands in the tens of thousands and is growing further thanks to the efforts of the GEOTRACES programme. In this tutorial I will review the new insights gained into the controls on the oceanic iron distribution that illuminates important roles for a range of sources and identifies crucial components of its biological cycling. These emerging ideas place important constraints on our efforts to represent the iron cycle in the global ocean models used for integrating to basin and global scales\, as well as climate prediction. In this context I will discuss how the role for iron in controlling past atmospheric carbon dioxide and future ocean productivity has matured. Finally\, I will highlight the key challenges that need to be tackled over the coming years\, with an emphasis on the opportunities provided by additional observational constraints. \n

SUMMARY:American Geophysical Union Fall 2015 Meeting
DESCRIPTION:American Geophysical Union Fall 2015 MeetingDates: 14-18 December 2015Location:  San Francisco\, California\, USA \nFor further information: http://fallmeeting.agu.org/2015/ \nGEOTRACES related sessions: \nGC067: Trace Metal Cycling in the Environment – 40 Years of AdvancementsConvenors: (1) Priya Ganguli (2) Frank Black (3) Sergio Sanudo-Wilhelmy (4) Ed BoyleSession ID#: 8771Invited Speakers:Rob Mason\, University of ConnecticutPeter Swarzenski\, US Geological SurveyKristen Buck\, University of Southern Florida \nOur understanding of metal cycling in the modern environment has been revolutionized by improvements in sample handling (i.e.\, trace metal clean techniques) and by innovations in technology. These advancements have enabled researchers to accurately quantify trace metal concentrations in a range of media (water\, air\, sediment\, biota)\, and thereby evaluate system response to key environmental reforms\, such as the U.S. Clean Water Act of 1972 and the global effort to phase out leaded gasoline\, which began in 1973. It is timely to assess our understanding of trace metal cycling in the modern environment as we embark on new global efforts to protect human and ecosystem health\, such as the 2013 Minamata Convention on Mercury. We solicit presentations on trace metal cycling in a variety of systems\, including water\, atmosphere\, sediment\, and biota. We are particularly interested in research that evaluates trends and/or draws biogeochemical links among environmental spheres._______________________________________Note: Russ Flegal\, who was instrumental in promulgating trace metal clean techniques and advancing our understanding of metal cycling in the environment\, is retiring from UC Santa Cruz this academic year. This session will provide an opportunity to celebrate the breadth of his contributions to the field. \nA035: Dust in High Latitudes: From its Origins to its ImpactsPrimary Convener: Santiago Gasso\, GESTAR/NASA\, Silver Spring\, MD\, United StatesSession ID#: 8015Conveners: John Crusius\, USGS Western Regional Offices Seattle\, Seattle\, WA\, United States\, Gisela Winckler\, Lamont -Doherty Earth Observatory\, Palisades\, NY\, United States and Paul A Ginoux\, NOAA Princeton\, Princeton\, NJ\, United States \nFrom long records of dust in ice cores to present day satellite imagery of dust blown off the coasts of Alaska\, Iceland and the Patagonia desert\, observations show how dust in high latitudes is pervasive and sustained over hundreds of thousands of years. High latitudes amplify dust effects on climate through their interactions with ice clouds\, reduction of surface albedo\, and the transport/supply of micronutrients to the surface ocean\, triggering phytoplankton blooms and affecting biogeochemical cycles. Yet\, most research on dust has focused on the subtropical regions and the areas around the dust belt. In this session we would like to focus on dust research at high latitudes\, and we invite presentations addressing all aspects of emission\, transport and impacts of dust (or volcanic ash) \, from the geologic past and the present\, as well as model simulations of the future. \n  \nOS010: Exploring the Dust-Ocean Connection in a Changing ClimatePrimary Convener: Maurice Levasseur\, Laval University\, Quebec-Ocean\, Quebec City\, QC\, CanadaSession ID#: 8749Conveners: William L Miller\, University of Georgia\, Athens\, GA\, United States and Mitsuo Uematsu\, University of Tokyo\, Bunkyo-ku\, Japan \nOcean-atmosphere interactions take different forms. Every year\, the atmosphere delivers massive amounts of nutrients to the global Ocean\, often relieving nutrient limitations and thus altering primary production and various related chemical pathways and feedbacks to the atmosphere. These fertilization events\, which include desert dust and volcanic ash depositions\, are episodic and mostly unpredictable\, hence notoriously difficult to study. While considerable advances have been made during the last few years on the global distribution of these deposition events and on their impact on ocean biogeochemistry the question remains: Can we confidently extrapolate current understanding to a high CO2 world? In this session\, we seek contributions on all aspects of this fascinating connection between the continents\, the atmosphere and the ocean. Papers exploring the importance of global change (climate warming\, change in wind patterns\, ocean acidification\, ocean stratification\, etc.) on dust emission\, transport and impact on the ocean are particularly welcomed.

SUMMARY:Quantifying fluxes and processes of trace-metal cycling at ocean boundaries
DESCRIPTION:Quantifying fluxes and processes of trace-metal cycling at ocean boundariesA two-day workshop to synthesize findings from the GEOTRACES programmeDates: 9th – 10th December 2015Location: Chicheley Hall\, Buckinghamshire\, UK \nFor further information: https://royalsociety.org/events/2015/12/trace-metal-cycling/ Questions about logistical issues: Kavli.events@royalsociety.org \nThis workshop will assess the state of understanding of trace metal fluxes at the four ocean boundaries: continents; marine sediments; the atmosphere; and mid-ocean-ridges. It will seek to quantify fluxes for key trace elements\, and describe as fully as possible the processes that control them\, so that changes to these fluxes in the past and future can be predicted. It will also identify areas where fluxes remain uncertain\, or tracers disagree\, and prioritise areas for future research. \nKeynote talks will be from: \nChris German (WHOI\, USA): Mid-ocean ridgesWill Homoky (Oxford\, UK): SedimentsJordi Garcia-Orellana (Barcelona\, Spain): Fluxes across the continental shelfSusan Little (Imperial College\, UK): Isotope tracing of boundary fluxesBill Jenkins (WHOI\, USA): Deconvolving fluxes from section dataCecile Guieu (Villefrance\, France): Lessons from the SOLAS ProgrammeBernard Peuker-Ehrenbrink (WHOI\, USA): The Great Rivers Observatory \nThere will be breakout discussion periods to consider each of the four ocean boundaries\, and the opportunity to show posters relevant to boundaries fluxes. Discussion will be summarised in a paper for each of the four boundaries. \nThere is a limit of 80 places at the workshop\, but we anticipate being able to accommodate most of those interested in attending. Applications to attend can be made at this site:https://royalsociety.org/events/2015/12/trace-metal-cycling/There is no cost to attend the meeting\, but delegates will need to cover their accommodation\, food\, and travel costs (though the workshop convenors are able to cover the costs of a small number of delegates). \nThis meeting follows directly after the two-day open meeting in London:“Biological and climatic impacts of ocean trace element chemistry” \nRegistration for which is open at this site:https://royalsociety.org/events/2015/12/ocean-chemistry/ \n \n

DESCRIPTION:Sustained ocean observing for the next decadeA combined GO-SHIP/Argo/ IOCCP conference on physical and biogeochemical measurements of the water columnDates: 14 – 18 September 2015Location: Galway\, Ireland \nFor further information: http://www.gaic2015.org \nGEOTRACES Oral presentation:  \n4D3. Biogeochemical Cycling of Trace Elements in the Ocean: Current and future opportunities linking GEOTRACES to Argo and GO-SHIPPeter CROOT1\, Greg CUTTER2\, Maeve LOHAN3 and Past and Present members of the GEOTRACES S&I Committee1National University of Ireland\, Galway; 2Old Dominion University; 3University of Plymouth  \n-> Friday\, 18 September 2015 – 15h50-16h10. \n Abstract: The international GEOTRACES (www.geotraces.org) program is focused on identifying the processes\, and quantifying the fluxes\, that control the distributions of key trace elements and isotopes (TEIs) in the ocean\, and to establishing the sensitivity of these distributions to changing environmental conditions. The successful launch in 2014 of the GEOTRACES intermediate data product (IDP) (http://www.geotraces.org/dp/idp2014) was the first release of the global dataset for TEIs and provides a valuable resource for ocean researchers. In the absence of open ocean CRMs for seawater\, quality control for the IDP2014 was achieved through community analysis of consensus samples (e.g. SAFe and GEOTRACES) by the GEOTRACES research community with oversight by the GEOTRACES Standards and Intercalibration Committee (S&IC). This presentation will provide an overview of the approaches used currently by the GEOTRACES S&IC in examining data quality and the potential for greater overlap with other programs such as GO-SHIP\, IOCCP and Argo in the future for examining the role of TEIs in ocean biogeochemistry and climate. \n

SUMMARY:Goldschmidt 2015
DESCRIPTION:Goldschmidt 2015  Dates: 16-21 August 2015 Location: Prague\, Czech Republic \nFor further information: http://goldschmidt.info/2015/index \nGEOTRACES sessions: \n \nTheme 2: Ocean Geochemistry. Present Conditions and Past Variation: fluxes\, reservoirs and processes \n \nCo-ordinators:Geraldine Sarthou (Brest University\, France)Andrew Bowie (University of Tasmania) \n \nTeam members:Katherine Barbeau (Scripps\, USA)\, Kristen Buck (Univ South Florida\, USA)\, Zanna Chase (Institute for Marine and Antarctic Studies\, Austra)\, Rob Middag (Univ Otago\, New Zealand)\, James Moffett (Univ. Southern Carolina\, USA) \n \nOur understanding of the functioning of the Earth system requires a knowledge of the broad spectrum of processes that influence chemical composition\, cycling and transfer of elements in the oceans and their interactions with the atmosphere\, land and crust. Ocean geochemistry aims to link and integrate studies of the modern oceans with work using proxies to define how ocean chemistry and the coupled ocean-atmospheric system has changed through the past on a number of different timescales. Critical to these efforts are considerations of how ocean chemistry influences and responds to biological activity and the impact of anthropogenic activity on the marine environment\, with important outcomes to issues as diverse as climate change and the capacity of the oceans to remove toxic metals. This theme welcomes submissions in a wide range of marine research areas\, including contemporary ocean composition and speciation\, transport processes in the ocean\, air-sea gas exchange\, paleo-oceanography\, to the evolution of the ocean due to environmental forcings such as acidity\, temperature\, and oxygen. \nTheme 2 sessions descriptions (complete abstracts of all presentations are available at Goldschmidt site\, please click on the links below to access the Goldschmidt webpage for each session): \n02a: Trace Metals in the Ocean: Distributions\, Isotopic Variation and SpeciationSession Convenors: Katherine Barbeau (UC San Diego\, Scripps Institution of Oceanography\, USA)\, Andrew Bowie (University of Tasmania)\, Kristen Buck (University of South Florida\, College of Marine Science\, USA)\, Rob Middag (Univ Otago\, New Zealand)\, Christopher Pearce (National Oceanography Centre)\, Phil Pogge von Strandmann (Earth Sciences\, University College London\, UK)\, Géraldine Sarthou (LEMAR CNRS\, Brest\, France). \nAbstract: Many trace elements are critical for marine life. However\, the mechanisms controlling how these metals influence the functioning of ocean ecosystems remain elusive. In conjunction with changes in concentration and speciation\, variations in metal stable isotopes provide enhanced discriminatory power for constraining these biogeochemical cycles\, as each process imparts a unique isotopic signature to the water column. The GEOTRACES program\, which aims to map the world’s oceans for trace elements and isotopes with unprecedented resolution\, combined with a growing inventory of metal isotope systems\, has facilitated rapid progress in this area. This session seeks to bring together scientists from recent oceanographic cruises to integrate results within and between ocean basins\, providing new insights on the behaviour of trace metals in the global ocean. We invite abstracts on all aspects of oceanic trace metal distributions and speciation\, as well as their isotopes (both radiogenic and stable)\, including their application to reconstructing past marine processes such as ocean circulation\, redox conditions and hydrothermal activity. We also encourage inter-calibration studies\, development of new analytical techniques and modelling work. \nKeynote speaker: Gideon Henderson (University of Oxford\, UK)Invited speakers: François Lacan (LEGOS CNRS\, Toulouse\, France) \n02b: Radionuclides in the OceanSession Convenors: Bob Anderson (Lamont-Doherty Earth Observatory\, USA)\, Ken Buesseler (Woods Hole Oceanographic Institution\, USA)\, Pere Masque (Universitat Autònoma de Barcelona) \nAbstract: Natural uranium/thorium series\, cosmogenic and anthropogenic radionuclides\, with their in-built “clocks” and contrasting geochemical properties and biological affinities\, have been instrumental for understanding and quantifying many important questions in oceanographic research. Examples include circulation and mixing of water masses\, particle cycling\, sediment and coral dating\, and fluxes at ocean boundaries\, amongst many other processes.  The Fukushima Dai-ichi disaster has also recently heightened public and policy concerns related to the human health effects of radioactivity attributable to external exposure from ocean contact and internal exposure from seafood consumption. Yet knowledge gaps remain regarding the spatial and depth distributions and the temporal evolution of many radionuclides of importance to both oceanographic and human health issues. This session will bring together scientists that are using radionuclides to better understand processes in the oceans through field based studies\, such as GEOTRACES\, laboratory experiments\, and modeling approaches.  This session will also accept presentations on advances in our methods for sampling and the analysis of ocean radionuclides.  More broadly\, the session will consider presentations on new tools to enhance public understanding of radioactivity\, and the education and training of the next generation of marine radiochemists. \nInvited speakers: Valentí Rodellas (Institut de Ciència i Tecnologia Ambientals\, Universitat Autònoma de Barcelona\, Spain)\, John Smith (Bedford Institute of Oceanography\, Canada)\, Walter Geibert (Alfred Wegener Institute\, Germany) \n \n02c: Past Changes in Ocean Biogeochemistry and Circulation and their Interaction with ClimateSession Convenors: Zanna Chase (Institute for Marine and Antarctic Studies\, Australia)\, Martin Frank (GEOMAR Helmholtz centre for ocean research Kiel\, Germany)\, Norbert Frank (University of Heidelberg\, Germany)\, Katharina Pahnke (ICBM and MPI for Marine Microbiology\, Germany)\, Laetitia Pichevin (University of Edinburgh\, UK)\, Laura Robinson (University of Bristol\, UK)\, Tina van de Flierdt (Imperial College London\, UK)\, Kazuyo Tachikawa (Cerege\, CNRS\, France) \nAbstract: Ocean biogeochemistry and circulation have influenced or even controlled climate on different time scales. Given that historical observations of ocean properties are restricted to the last ~100 years\, it is essential to reconstruct their involvement in Earth’s climate prior to human induced changes.Trace-element and isotope geochemistry offer powerful tools to constrain such changes. For this session we invite contributions addressing past ocean circulation\, productivity and nutrient cycling based on stable\, radiogenic\, or radioactive isotope signatures or other geochemical tracers from millennial to million year time-scales from the recent past to deep time\, from bulk sediment to deep-sea corals. We also encourage contributions that integrate proxy data and models to understand the dynamics of past ocean circulation. \nKeynote speaker: Jess Adkins (California Institute of Technology\, USA)Invited speaker: Ruza Ivanovic (University of Leeds\, UK) \n02d: What are the unifying principles common to all three Oxygen Minimum Zones (OMZs)?Session Convenors: Jim Moffett (Univ. Southern Carolina\, USA)\, Aurélien Paulmier (LEGOS\, France) \nAbstract: Oxygen minimum zones (OMZs) arise from a combination of high productivity on overlying waters and sluggish rates of ventilation within their core\, giving rise to strong oxygen deficits.  In three OMZs (the Arabian Sea\, Eastern Tropical South Pacific\, and Eastern Tropical North Pacific) oxygen is probably effectively zero\, based on recent sensor data.   These are important areas for fixed nitrogen loss on a global scale. Other OMZs\, including the Benguela Upwelling and Bay of Bengal\, are poised to become denitrifying on a large scale but are not so at present. These regions have complex geochemistry and a global significance that extends beyond the nitrogen cycle alone. They are critical domains in which to investigate global change\, with shifts in redox chemistry and their boundaries evident or predicted to occur in the near future. Moreover\, carbon preservation in underlying sediments makes them excellent regimes to study past changes in ocean processes. The purpose of this session is to explore the biogeochemical features common to all OMZs as well as the features that make them different.Many nations have mounted expeditions to study OMZs in recent years\, including several European nations\, Japan\, the USA and states bordering OMZs\, particularly Peru\, Chile and India. Three cruises in the International GEOTRACES program have been staged in denitrifying OMZ regions since 2009\, by Japan\, the USA and India. Researchers from these and other programs\, as well as benthic studies are encouraged to participate in this session. \nKeynote speaker: Bess Ward (Princeton University\, USA)Invited speakers:  Niels Peter Revbesch (University of Aahrus\, Denmark)\, Marcel Kuypers (MPI for Marine Microbiology\, Germany)\, Phyllis Lam (NOCS\, UK)\, Sunil Singh (Physical Research Laboratory\, India) \n02e: Air-Sea Exchange\, the Biological Pump\, and Ocean AcidificationSession Convenors: Steve Emerson (University of Washington\, USA)\, Doug Wallace (Dalhousie University\, Canada) \nAbstract: The pCO2 content of the atmosphere is regulated by exchange with the upper ocean via the solubility and biological pumps.  About one quarter of the anthropogenic CO2 introduced to the atmosphere is ultimately stored in the ocean causing a decrease in pH.  Understanding the physical\, biological and chemical processes controlling the atmosphere-ocean carbon cycle are key to accurate predictions of ocean feedbacks to global warming. While there have been great advances on the relationship between air-sea exchange and wind speed\, mechanisms controlling the fluxes are still uncertain.  Satellite-based estimates of the biological pump predict geographic variations that are not observed in upper-ocean\, mass-balance studies.  The response of ocean pH to the anthropogenic CO2 invasion is nearly certain\, but generalizations about the effects on marine biology are still tenuous.  This session explores recent advances in marine carbon cycle studies in the upper ocean and atmosphere. \nInvited speakers: Henry Bittig (Helmholtz Ctr for Ocean Research\, Kiel\, Germany) and Jan Kaiser (University of East Anglia\, U.K.) \n02f: Biogeochemistry of Arctic and Antarctic sea ice systemsSession Convenors: Jun Nishioka (Univ. Hokkaido\, Japan)\, Delphine Lannuzel (University of Tasmania\, Australia) \nAbstract: Observations have demonstrated that sea ice is biologically and chemically active in the global biogeochemical cycles. However\, Earth system models currently represent sea ice as biologically and chemically inert. The aim of this session is to bring together those working on all aspects of sea ice biogeochemistry to gain a better understanding of the exchanges at the interface between sea ice and the atmosphere and sea ice and the ocean. We particularly encourage presentations on processes involved in the distribution of macro-nutrients\, trace metals and organic carbon\, as well as the uptake and production of climatically-important gases such as CO2\, CH4\, and DMS. \nKeynote speaker: Martin Vancoppenolle (LOCEAN CNRS\, Paris\, France) \n02g: Advances in marine N\, P and Si biogeochemistrySession Convenors: Damien Cardinal (University Pierre and Marie Curie\, LOCEAN\, Paris)\, Albert Colman (University of Chicago\, USA)\, Masha Prokopenko (University of Southern California\, USA)\, Christian März (Newcastle University\, UK) \nAbstract: Nitrogen\, phosphorus and silicon are critical nutrients that help govern net primary production in the oceans and the efficiency of carbon export from the euphotic zone. Though their cycles are coupled\, each element has a very distinct cycle with regard to ocean sources and sinks\, modes of internal recycling and residence times. The biological requirements\, remineralization pathways\, and chemical characteristics (redox state\, solubility\, coupling with carbon) diverge in many important ways\, leading to formation of biogeochemically diverse oceanic regions. In the recent years numerous methodological advances have been developed and several basic concepts revisited with regard to these key macronutrients (e.g. diazotrophy\, Redfield Ratios…). This session will focus on the new insights gained by application of such analytical and modeling approaches. We will particularly encourage contributions dealing with inter-elemental (de)coupling\, multi-spatial scales (from cell to global)\, and/or multi-temporal scales (from geologic past to future). \nKeynote speaker: Laetitia Pichevin (University of Edinburgh\, UK)Invited speakers: Greg de Souza (Princeton University\, USA)\, Kate Hendry (Bristol University\, UK)\, Caroline Slomp (University of Utrecht\, The Netherlands)\, Claire Mahaffey (University of Liverpool\, UK)\, Curtis Deutsch/Tom Weber (University of Washington) \n02s: Goldschmidt 25th Anniversary \nCatherine Jeandel\, GEOTRACES IPO senior scientist\, reviewed the last 25 years of marine geochemistry.
