SUMMARY:Challenger Society 2016 Conference - Oceans and Climate
DESCRIPTION:Challenger Society 2016 Conference – Oceans and ClimateDates: 5-8th September 2016Location: Liverpool\, UK. \nFor further information: https://www.liverpool.ac.uk/challenger-conference-2016/ \nGEOTRACES session: \nTrace element and isotope exchange at ocean boundariesConveners: Will Homoky (Oxford)\, Torben Stichel (Southampton) & Susan Little (Imperial) \nTrace elements and their isotopes (TEIs) play a key role in the ocean\, as micronutrients and toxicants for primary production\, as indicators of anthropogenic inputs\, as tracers of modern and past ocean circulation\, and as proxies of the paleooceanic environment. A variety of ocean boundaries mediate the exchange of TEIs between the Earth and ocean\, including the atmosphere\, rivers\, groundwater\, glaciers\, sediments and sub-aqueous volcanism. However\, for many TEIs we have very little knowledge about the rates and mechanisms controlling their exchange. We invite studies of observed and/or modelled exchange of TEIs at ocean boundaries that provide new insights into these processes. \n

SUMMARY:Biogeochemical cycling of trace elements within the ocean: A synthesis workshop
DESCRIPTION:Biogeochemical cycling of trace elements within the ocean: A synthesis workshopDates: 1-4 August 2016Location: Lamont-Doherty Earth Observatory\, Palisades\, NY\, USA \nThe first and the second announcements are available to download. \nFor further information: http://web.whoi.edu/geotraces-synthesis/ \n  \nBackground \nGEOTRACES is producing a wealth of new data for trace elements and their isotopes (TEIs) in the ocean\, including a suite of essential micronutrients and chemical tracers of carbon flux. GEOTRACES seeks to engage a wider spectrum of expertise for the synthesis and further application of these data in order to maximize benefits to the broader oceanographic community. There is heightened interest and momentum in the Ocean Carbon and Biogeochemistry (OCB) community to integrate these types of data into studies of the biological pump and feedbacks between marine organisms and biogeochemistry\, particularly in the face of newly emerging research initiatives such as EXport Processes in the Ocean from RemoTe Sensing (EXPORTS)\, North Atlantic-Arctic\, and Global scale Microbial Interactions across Chemical Surveys (GeoMICS). \nTrace element micronutrients play a vital role in regulating the growth of marine organisms\, which\, in turn\, are key players in modulating the biogeochemical cycling of trace elements. This workshop will bring together expertise from GEOTRACES\, OCB\, and the broader oceanographic community of observationalists and modelers to explore the biological-chemical-physical underpinnings of trace element cycling in the ocean\, including (but not limited to) bioavailability\, uptake\, scavenging\, and regeneration.  \nWorkshop organizing committee   \nRobert Anderson (Lamont-Doherty Earth Observatory)Kathy Barbeau (Scripps Inst. Oceanography)Heather Benway (OCB Project Office)Mark Brzezinski (Univ. California\, Santa Barbara)Kristen Buck (Univ. South Florida)P.

British Columbia)Keith Moore (Univ. California\, Irvine)Alan Shiller (Univ. Southern Mississippi)Alessandro Tagliabue (Univ. Liverpool)Benjamin Twining (Bigelow Laboratory) \n\n\n\n\nSponsors   \n GEOTRACES and the Ocean Carbon and Biogeochemistry Program (OCB). \n \nObjectives  \nThe workshop will launch a synthesis initiative on the biogeochemical cycling of trace elements and their isotopes within the ocean. We aim to bring together expertise from GEOTRACES\, OCB\, and the broader oceanographic community of observationalists and modelers to explore the biological–chemical–physical underpinnings of trace element cycling\, including (but not limited to) bioavailability\, uptake\, scavenging\, and regeneration. The workshop will identify a small number of high-priority synthesis objectives that can be achieved over the next decade\, exploiting the rapidly expanding set of data from GEOTRACES and related studies. The workshop will also outline strategies to reach those goals\, which may include new modeling and observational initiatives. \nPlenary talks at the beginning of the workshop (see list of speakers) will stimulate discussion in the working groups that follow by presenting relevant background information together with novel hypotheses emerging from new data sets.  \nRegistration  \nRegister via the workshop website: http://web.whoi.edu/geotraces-synthesis/registration/ \nTravel Support  \nTravel support is available for about 60 participants in the form of subsidies for airfare and ground transportation (capped depending on travel origination – see below*). Hotel rooms and meals will be provided by the organizers. Those who can cover their own travel expenses are encouraged to do so. \nInformation about travel arrangements (airports\, ground transportation) will be posted on the web site together with the registration page. \nTo apply for a travel subsidy\, include with your registration a brief (maximum 250 words) description of your relevant expertise and anticipated contribution to the workshop. This document can be uploaded on the registration web site. \n*Tentative subsidy cap (U.S. Dollars) for airfare\, ground transportation\, and incidental expenses: \nEastern North America – $500Western North America – $750Alaska and Hawaii – $1000Overseas – $2000 \nDeadlines \nDeadline to register and request a travel subsidy: 1 June 2016 \nThe planning committee will select participants to receive travel support based on a review of the application material received by the deadline. The anticipated contribution to the workshop goals will be used as the basis for selection among the applicants. \nDeadline to register without travel subsidy: 1 July 2016 \nThe total number of participants is limited to 80.

SUMMARY:32th International Conference on Environmental Geochemistry and Health
DESCRIPTION:32th International Conference on Environmental Geochemistry and HealthDates: 4-8 July 2016Location: Brussels\, Belgium \nFor further information: segh-brussels.sciencesconf.org \nRelevant Session description: \nThis theme aims at providing a better understanding of the near surface environment where complex interactions between rock\, soil\, water\, air\, and living organisms that regulate sources\, sinks\, geochemical cycles and mobilization processes of life-sustaining resources. In addition to well-recognized contaminants (e.g. Pb\, Zn\, Hg)\, a range of trace elements\, including platinum group metals\, certain rare earth elements\, and Y\, Nb\, Ta\, Ga\, In\, Tl\, Ge and Te\, are increasingly exploited and emitted due to their use in new technologies in the fields of communication\, mobility and energy. Limited resources and supplies\, make most of these elements technology-critical elements (TCE) of strategic importance\, and initiatives at national and international levels are therefore underway to secure their availability in the coming years. Because of their (i) increasing use\, (ii) poorly understood biogeochemical behavior and (iii) potential toxicity\, TCE and other rare trace elements are emerging inorganic contaminants of substantial concern. \nSpecial attention will be paid to trace element and isotope analyses and monitoring to detect and model bioavailability and bioaccessibility of such metals and other pollutants in the environment and the associated risks to human health. In addition\, we welcome papers focusing on models helping speciation of key geochemical elements in aquatic and terrestrial environments. \nThis session is supported by the COST Action TD1470 NOTICE –Network On Technology-Critical Elements: From Environmental Processes To Human Health Threats (http://www.costnotice.net/)

SUMMARY:Goldschmidt 2016
DESCRIPTION:Goldschmidt 2016Dates: 26 June – 1 July 2016Location: Yokohama\, Japan \nThe abstract deadline is 26 February 2016.  \nFor further information: http://goldschmidt.info/2016/ \n  \nGEOTRACES Workshop: \nExploring GEOTRACES data with Ocean Data View     ***For more information please go to the Workshop website*** \nOrganizers: Jing Zhang\, Reiner Schlitzer\, Elena Masferrer Dodas \nThis hands-on workshop will teach standard and advanced ODV methods for the exploration and scientific analysis of environmental data. The GEOTRACES Intermediate Data Product 2014 (IDP2014) will be used as example dataset. Participants will learn how to create publication-ready maps\, property-property plots and sections and how to apply simple or advanced station and sample filters. In addition\, an overview over the wide range of derived variables available in ODV will be given and a number of variables often needed in geochemical research will be described and applied. This includes aggregation\, interpolation\, unit conversion\, differentiation and integration. Note that creation of spinning 3D scenes is beyond the scope of this workshop. The workshop starts with presentations of general software concepts and capabilities\, followed by hands-on-sessions for the creation of specific plot types and scientific discussion rounds explaining the findings. Participants are encouraged to bring their own laptop computer with ODV (http://odv.awi.de/) and the IDP2014 dataset (http://www.bodc.ac.uk/geotraces/data/idp2014/) already installed. Specific requests by participants prior to the workshop or during the event are welcome. \nGEOTRACES sessions: \n12d: Oceanic Cycling of Trace Elements Using Elemental\, Isotopic\, and Modeling Approaches: Geotracers and Beyond… \nConvenors: Tim Conway\, Tristan Horner\, Jessica Fitzsimmons\, Hajime Obata\, Catherine Jeandel\, Andrew Bowie\, Phoebe LamKeynote: Sylvia Sander (University of Otago) \nAbstract: The distribution of trace elements and their isotopes in the oceans results from a myriad of processes\, with these elements serving critical roles as regulators of ocean biogeochemistry including marine ecosystem dynamics. Despite this\, we still lack a complete understanding of not only the mechanisms by which these elements influence the functioning of ocean ecosystems\, but also the controls on the transfer of these elements at oceanic interfaces (e.g. atmospheric\, ice\, sedimentary\, shelf\, rivers\, and hydrothermal interfaces)\, and the processes that transform these critically important elements within the ocean interior. Recent concerted international endeavors such as the GEOTRACES Program are changing this picture and enabling a coherent landscape of oceanic trace element cycling to emerge. Accordingly\, this session seeks to bring together scientists from recent oceanographic expeditions to integrate results within and between ocean basins. We invite abstracts on all aspects of oceanic dissolved and particulate trace element distribution and speciation\, and we encourage submissions that apply novel analytical methods to understand elemental and isotopic (stable and radiogenic) distributions in the oceans\, including those that address metal speciation\, ligand binding\, and size-fractionated distributions. We especially encourage submissions that utilize modeling approaches which draw on new datasets and/or which aim to constrain the biological and chemical processes that determine the distributions of trace elements in seawater in the context of large-scale physical mixing\, or past and present ocean circulation\, redox conditions and hydrothermal activity. \n12f: Elemental and Isotopic Marine Biogeochemistry at a Range of Scales: The Global Ocean\, Marginal Seas\, and Polar Atmosphere–Sea Ice–ocean Systems \nConvenors: Susan Little\, Daiki Nomura\, Gregory de Souza\, Markus Frey\, Delphine Lannuzel\, Jun Nishioka\, Patrick Rafter\, Martin VancoppenolleKeynote: Daniel Sigman (Princeton University) \nAbstract: We invite observational and modelling studies of marine elemental and isotopic biogeochemical cycling at a range of spatial scales. Our broad purview includes large-scale studies of macro- (N\, Si) and micronutrients (e.g. Zn\, Fe\, Cu\,) and other biogeochemically-cycled elements (e.g. Ba\, Cd)\, as well as regional studies with a focus on the biogeochemistry of the the polar sea-ice zone (Arctic and Antarctic). By providing an interdisciplinary forum\, this session aims to find parallels (and contrasts) between the isotope systems of macro- and micro-nutrients\, and to better understand the components\, drivers\, processes and interfaces related to the cycling of carbon\, nutrients\, and trace elements and their isotopes (TEIs) within the polar atmosphere–sea ice–ocean system. Studies covering the spectrum of possible scales from whole-ocean budgets to molecular-scale fractionation are solicited\, especially those that form a part of the GEOTRACES programme. In particular\, we invite studies attempting to pick apart the roles of the physical circulation and internal oceanic cycling (e.g. biological uptake\, scavenging\, speciation) on tracer distributions\, including the role of particulates and their associated TEI distributions. Submissions from the polar hydrosphere\, atmosphere and cryosphere are solicited\, including those related to polar climate change\, river-ocean interaction\, snow and sea ice physics and biogeochemistry\, polar atmospheric chemistry and ocean acidification. \n16d: Models of Life and Geochemistry: Integrating Large-Scale Datasets into Global Climate Models \nConvenors: Seth John\, Tatiana Ilyina\, Andy Ridgwell \nAbstract: ew global datasets and global modeling techniques can be brought together to study questions of biological\, geochemical\, and climatic importance. This session focuses on the utilization of large-scale datasets within a variety of modeling frameworks. Recent global datasets include shipboard ocean chemical observations such as GEOTRACES and WOCE\, shipboard time-series programs\, and sensor data such as Argo\, mooring\, and remote sensing data. Each of these observational datasets can be studied within the context of various global modeling techniques including coupled GCMs and high-resolution regional models as well in conjunction with relatively newly developed and numerically-efficient global-scale tools such transport matrix models (TMMs) and decadal predictions systems. We seek contributions from scientists working across a broad spectrum of global biogeochemical cycles including carbon\, nitrogen\, oxygen\, nutrient\, trace-metal\, and particle distribution in the oceans\, and the application of such tracers for constraining ocean circulation as well as sources and sinks of biologically and geochemically important elements and their variability in the ocean. We also encourage submissions rooted in modern geochemical observations that address future biogeochemical changes in the ocean by forward modelling. \nGEOTRACES related-sessions: \n14j: Linked Landscapes: Biogeochemical Connections Among Headwater Streams\, Rivers\, Estuaries and Coastal Ecosystems \nConvenors: Nobuhito Ohte\, David Widory\, Scott Wankel\, Taylor Maavara\, Philippe Van Cappellen\, Pierre Regnier\, Ronny Lauerwald\, Dipankar Dwivedi\, Carl Steefel \nAbstract: Rivers and their surrounding landscapes are the great integrators of the freshwater cycle and they represent the main pathway for biogeochemical transfers from land to ocean. An understanding of the mechanisms governing the linkages throughout the aquatic continuum is crucial for predicting ecosystem function\, water quality\, greenhouse gas emissions and the role of the coastal ocean in global carbon budgets. The structure and function of riverine\, estuarine and coastal ecosystems are strongly affected by surrounding terrestrial ecosystems through a combination of hydrologic and biogeochemical dynamics and feedbacks\, including hyporheic exchange. However\, a mechanistic understanding of the nature of these linkages and feedbacks is lacking\, particularly at the watershed- to global-scales. Investigating these knowledge gaps is complicated by the unprecedented rates of change over the last 100 years to the absolute and relative fluxes of elements such as C\, N\, P\, S\, Si\, Fe and Ca\, delivered by rivers to lakes and coastal zone. Here\, we invite observational and theoretical contributions that identify and characterize: 1) biogeochemical linkages among terrestrial\, river and coastal ecosystems\, 2) the influence of local settings (geology\, hydrology\, climate\, ecotypes\, etc.) on these biogeochemical linkages\, and 3) the time-dependent and coupled responses of riverine biogeochemical fluxes and transformations to anthropogenic drivers. Specific topics may include\, but are not limited to\, eutrophication and nutrient loading in aquatic systems\, internal nutrient recycling\, nutrient elimination/mitigation\, river damming and channelization\, multi-scalar properties of the hyporheic exchange flows that impact nutrient cycling\, and impacts on trace gas fluxes (e.g.\, methane\, nitrous oxide). \n15b: Radionuclide Fate and Transport after the Fukushima Accident: Identifying What We Have Learned and Remaining Knowledge Gaps \nConvenors: Anne Mathieu\, Daniel I. Kaplan\, Yoshiho Takahashi\, Seigo Amachi\, Fan Qiaohui\, Yuichi Onda\, Chris Yeager\, Tsuyoshi Thomas Sekiyama\, Mizuo KajinoKeynote: Yuichi Onda (Tsukuba University) \nAbstract: In 2011\, an earthquake of magnitude 9\, followed by a tsunami\, triggered a major nuclear accident at the Fukushima Daiichi Nuclear Power Plant that released radionuclides in the environment. Five years after the Fukushima disaster\, a milestone has been reached. One of the key conclusions made to date\, is that while many studies have identified similarities to other nuclear accident sites\, such as Chernobyl\, studies have also revealed new insights into radionuclide transport owing to the circumstances surrounding the Fukushima accident\, such as the direct injection of radioactivity into the ocean. While significant progress has been made\, many uncertainties remain. The objective of this session is to not only present advances\, but also identify key knowledge gaps that are limiting further advancement in these areas of research. Any research on the fate and transport of radionuclides related to the Fukushima accident is welcome in this session. In particular\, papers are encouraged that integrate monitoring\, experimental\, and/or modeling approaches to add perspective and understanding to the recent accident in Fukushima. Relevant topics also include radionuclide biogeochemistry influencing transport in terrestrial and marine systems. \n15e: Isotope Approaches to Characterize the Impacts of Natural Resource Development and Other Human Activities on the Environment \nConvenor: Millot RomainKeynote: Nathaniel R. Warner (Pennsylvania State University) \nAbstract: Recent analytical developments of isotope systematics\, for instance metals and metalloids (Hg\, Cr\, Zn\, Cu\, Pb\, Cd\, Tl\, Ag\, Sn\, U\, Fe\, Se\, Mo\, U\, Ra\, Th) in the Environment\, have experienced an unprecedented increase over the past few years. It is well known that: 1- metals mining and both conventional and unconventional hydrocarbon extraction can have a considerable environmental footprint\, 2- within the framework of the exploitation of unconventional gases and oil\, chemical elements potentially toxic to humans and wildlife (called the radionuclides toxic metals: RTM) pollute the flowback\, 3- more generally the contribution of human activities such as industries\, agriculture and various domestic inputs\, becomes more and more significant in natural systems.The aim of this session is to explore methods\, indicators and research applications using innovative isotope systematics of elements such as H\, C\, N\, O\, S and Hg\, Zn\, Cr\, Cu\, Cd\, Mo\, Ag\, Se\, that in fine will provide: i) stronger constraints on the origin(s) and ii) a better characterization of the processes controlling the budgets of toxic metals and compounds in the Environment (e.g.\, soil\, sediment\, water\, air) at local and global scales\, in addition to transfer of these constituents to the food chain and potential effect on human health. \n15l: Advances in Mercury Biogeochemistry \nConvenors: Colin Cooke\, Jeroen SonkeKeynote: Daniel Obrist (DRI\, Reno Nevada\, USA) \nAbstract: Mercury is a global pollutant that\, once converted to methylmercury\, can negatively impact human health. Present-day anthropogenic emissions of mercury are approximately an order of magnitude greater than natural emissions\, and the chemical speciation of Hg dramatically affects its mobility and toxicity. Understanding the environmental cycling of mercury is paramount if reductions to mercury exposure are to be achieved. We invite presentations focused on field\, laboratory and modeling studies of the sources\, transport and fate of mercury in Earth surface environments (atmosphere\, oceans & continents)\, including human exposure. We particularly welcome the use of novel approaches including but not limited to genomics\, enriched Hg isotopes\, stable Hg isotopes\, spectroscopy\, 3D coupled models\, Hg-Se interactions etc. \n16a: Tracing Ocean Circulation – Past and Present \nConvenors: Ruza Ivanovic\, Tina van de Flierdt\, David WilsonKeynote: Geoffrey (Jake) Gebbie (Woods Hole Oceanographic Institution) \nAbstract: Ocean circulation is an important part of the Earth system\, playing a key role in controlling or responding to climate change. With limited direct observations for ocean currents and mixing\, geochemical tracers are a valuable tool for reconstructing ocean circulation\, past and present. Increasingly\, such tracers are being incorporated into complex numerical climate models\, the observational database is being expanded\, and better knowledge of what influences the geochemical archives is being gained. These recent improvements in modelling and measuring tracers enable a more thorough understanding of ocean-climate interactions on a range of timescales. For this session\, we invite contributions that use measured and/or modelled geochemical tracers to constrain ocean dynamics in the past and present. We particularly encourage submissions that link changes in ocean circulation and mixing with surface climate.

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
