SUMMARY:Goldschmidt 2013
DESCRIPTION:Goldschmidt 2013   Dates:   25-30 August 2013 Location: Florence – Italy  \nFor further information: http://goldschmidt.info/2013/index \n  \nGEOTRACES Relevant Special Sessions: \n \n* 16h. Chemical Weathering in Marginal EnvironmentsConvenors: Bernhard Peucker-Ehrenbrink and Morgan JonesKeynote: Catherine Jeandel (LEGOS\, Toulouse) \nThis session aims at focusing on chemical weathering processes not taking place in the soils but in deeper aquifers\, in floodplains\, in estuaries and in marine sediments. It is of particular importance to evaluate the diversity of processes at play and their quantitative importance. Is our view of the global chemical weathering picture or global carbon cycle significantly modified when these marginal weathering environments are taken into account? \n \n*17a. The ins and outs of mud: chemical fluxes between sediments and seawaterConvenors: Silke Severmann and Rachel Mills Keynote: Ronnie N. Glud (University of Southern Denmark) \nMarine sediments are the ultimate sink for many constituents in seawater\, but this flux is significantly moderated at the seafloor before burial. Solute exchange between marine sediments and the overlying water column is occurring throughout the ocean basins. Elemental mass fluxes operate in both directions\, often with profound effects on the local or global seawater chemistry. Rates of exchange are sensitive to various internal and external forcing mechanisms that operate on seasonal to geological time scales. In the shelf seas the benthic boundary layer communicates with the surface ocean through upwelling and mixing\, thus providing a feedback between primary productivity and benthic respiration. Seafloor exchange in the deep ocean can contribute significantly in terms of the element’s global mass balance. Microbial processes are important drivers for many of these exchange processes in shallow and deep-sea sediments. \nTechnical innovations have led to improved quantification of these fluxes in the modern ocean\, while development of novel paleo-proxies provide new insight into changes in the nature and rate of benthic-pelagic exchange over longer time scales. This session invites contributions that examine the process regulating benthic exchange\, as well as techniques to quantify these fluxes on a variety of time scales. \n \n* 17b. Constraining rates of ocean processesConvenors: Laura Robinson and Matt Charette Keynote: Bill Jenkins (WHOI) \nImportant physical\, chemical\, and biological processes in the ocean occur over a wide range of timescales from seconds up to millennia. Geochemical tracers provide tools to assess the rates and timescales of these processes. For example radiocarbon\, nuclear bomb test products and long-lived U-series isotopes have been used to look at oceanic overturning circulation rates. Radiogenic thorium has been used to quantify fluxes of particles (and carbon) through the water column and to the seafloor\, and radium has been used examine the extent of lateral advection from the continents to the ocean interior. These and other traditional and novel approaches provide insight into ocean mixing and biogeochemical cycling processes central to the ocean’s interaction with the Earth system as a whole. In this session we welcome contributions that use geochemical approaches to examining the rates of oceanic processes both in the modern ocean and in the past. Invited speakers – Bob Anderson and Pieter Van Beek. \n \n*17d Isotope geochemistry of the modern oceansConvenors: Seth John \, Julie Granger\, Katharine Pahnke and Gregory F. de SouzaKeynote: Curtis Deutsch (University of Washington) \nIsotopic tracers are a powerful tool for studying the balance between physical circulation and biogeochemical processes that govern the cycling of elements within the global ocean. While the impact of the large-scale circulation on the marine distribution of radiogenic isotopes has long been recognized\, the recent increase in measurements of stable isotopes in seawater has made it also possible to observe interactions between circulation and stable isotope distributions. This session aims to bring together these two fields by encouraging contributions pertaining to stable isotope constraints on the cycling of globally important macro- and micronutrients (e.g. nitrate δ15N\, nitrate δ18O\, δ30Si\, δ56Fe\, δ114Cd)\, as well as isotopic proxies that trace ocean circulation pathways (e.g. εNd). To this end\, we explicitly solicit contributions from both the modeling and observational communities. While this session emphasizes isotopic tracers\, other data (e.g. trace elements) that elucidate the interactions between physical circulation and biogeochemical processes governing marine elemental distributions in the modern or past ocean are also welcome. \n*17g Metal-biota interactions in seawaterConvenors: Jay Cullen\, Maeve Lohan and Martha GledhillKeynote: Mak Saito (Woods Hole) \nRecent advances in analytical chemistry and molecular biological techniques indicate that trace metal micronutrients play an important role in regulating the species composition and physiological rate processes of the marine microbial community. Fully understanding the marine carbon and nitrogen cycles is thus intimately tied to our efforts to determine the distribution\, chemical speciation and resulting bioavailability of trace metals to the marine biota. New and fruitful collaborations between chemical oceanographers and microbial physiologists are being achieved through\, for example\, high spatial resolution data as obtained via the ongoing international GEOTRACES program (www.geotraces.org). We invite submissions to this session which highlight trace metal-biota interactions and the complex interlacing of geochemical\, physiological and ecological maps which shape the tempo and mode of carbon and nitrogen transformations in the ocean. \n​

SUMMARY:AOGS 2013\, Asia Oceania Geosciences Society Annual Meeting
DESCRIPTION:2013 Asia Oceania Geosciences Society Annual Meeting (AOGS2013)Dates: 24-28 June 2013Location: Brisbane\, Australia \nFor futher information: http://asiaoceania.org/aogs2013/public.asp?page=home.htm \nGEOTRACES Relevant Session: \nControls on the Biogeochemistry of the Northwestern Pacific Ocean and its Adjacent Marginal SeasMain Convener: Dr. Tung-Yuan Ho (Academia Sinica\, Taiwan)Co-conveners: Dr. Sohrin Yoshiki (Kyoto University\, Japan)\, Prof. I-I Lin (National Taiwan University\,Taiwan) and Dr. George T F Wong (Academia Sinica\, Taiwan) \nThe Northwestern Pacific Ocean and its adjacent marginal seas is an important and notable biogeochemical province in the world’s oceans. It includes the largest marginal sea of the world\, the South China Sea\, and some world class shelf-seas (e.g.\, the East China Sea and Northern South China Sea Shelf-sea and the Sunda Shelf). Its biogeochemistry is driven by diverse anthropogenic and natural forcings at strengths that are among the strongest in the world. They include riverine inputs from some of the major rivers of the world such as the Changjiang\, Huangho\, Pearl River and Mekong River\, atmospheric deposition with material from multiple origins (including desert dust\, volcanic aerosols\, anthropogenic aerosols\, biomass burning) at some of the highest fluxes in the world\, typhoons occurring at frequencies and strengths that are among the highest in the world\, internal waves with amplitudes that are almost unmatched in the world and one of the two primary western boundary currents in the world’s oceans. In addition\, it is also affected by global phenomena such as El Niño-Southern Oscillation\, La Niña\, ocean acidification and global warming. This joint (BG-OS-AS) session welcomes submissions of studies from broad disciplines in the biogeochemistry of the region\, including observations\, modeling\, and remote sensing efforts.

SUMMARY:ASLO 2013\, Aquatic Sciences Meeting
DESCRIPTION:ASLO 2013\, Aquatic Sciences MeetingDates: 17-22 February 2013Location: New Orleans\, Louisiana \nFor further information: http://www.aslo.org/meetings/neworleans2013/ \nGEOTRACES relevant sessions: \n**SS57: Trace Elements and Isotopes in the Ocean and Atmosphere: the International GEOTRACES ProgramConveners: Peter Morton\, Florida State University; Carl Lamborg\, Woods Hole Oceanographic Institution. \nThe international GEOTRACES program is a multi-nation and multi-year effort to determine the concentration and speciation of trace elements and select isotopes in the world’s major ocean basins and some marginal seas at high vertical and horizontal resolution\, reminiscent of the GEOSECS program. This program’s goal is “to improve the understanding of biogeochemical cycles and large-scale distribution of trace elements and their isotopes in the marine environment.” ( www.geotraces.org). To date\, 35 “GEOTRACES compliant” section and process cruises have been completed and many more are planned. For this session\, we invite investigators to share their findings from any GEOTRACES cruise including those related to dissolved and particulate trace elements\, isotopes\, nutrients and dissolved gases as well as atmospheric analyses. We also welcome presentations describing intercalibration\, data management and modeling efforts related to GEOTRACES process and section studies. \n**SS08: Biogeochemistry of Metal-binding Organic Ligands in the Ocean: Sources\, Composition and Impacts on Trace Metal CyclingConveners: Maeve C. Lohan\, University of Plymouth; Sylvia G. Sander\, University of Otago; Kristen N. Buck\, Bermuda Institute of Ocean Sciences \nThe bioactive trace metals iron\, copper\, cobalt\, nickel\, zinc and cadmium are essential micronutrients for marine phytoplankton and exert a major influence on the global carbon cycle. Complexation of these metals by organic ligands may enhance or reduce bioavailability depending upon the metal-ligand complex formed. Yet we know little about the composition\, sources and cycling of metal-binding ligands\, which is hindering further advances in the field of trace metal biogeochemistry. An active SCOR Working Group (WG 139) ‘Organic Ligands- A Key Control on Trace Metal Cycling in the Ocean’ fosters the multidisciplinary collaboration of trace metal biogeochemists\, organic geochemists and biogeochemical modelers in order to advance this field. This session is a community wide forum to highlight recent accomplishments in metal-binding ligand characterization and approaches for assessing ligand composition\, sources and impacts on trace metal cycling in the aquatic environment\, and to discuss future efforts in this field. We welcome abstracts related to metal-binding ligands from throughout the multidisciplinary field of oceanography.

SUMMARY:American Geophysical Union Fall 2012 Meeting
DESCRIPTION:American Geophysical Union Fall 2012 MeetingDates: 3-7 December 2012Location:  San Francisco\, California\, USA \nFor more information: http://fallmeeting.agu.org/2012/ \nGEOTRACES Relevant sessions: \n **OS013: Isotope Tracers in the 21st Century Ocean: New Results\, Interesting Challenges\, and Unique OpportunitiesConveners: Steven L Goldstein (Columbia University)\, Alison E Hartman (Lamont-Doherty Earth Observatory)\, Howie D Scher (University of South Carolina) and Torben Stichel (University of Hawaii at Manoa). \n Bioactive\, particle-reactive\, and provenance-sensitive elements with isotopic variability in seawater are widely used to trace present and past processes in the oceans. Current research efforts\, such as GEOTRACES\, are increasingly multi-proxy\, high resolution\, and require smaller samples due to recent advances in mass spectrometry. Together these advances provide unprecedented opportunities to address source-to-sink questions and integration of tracers of different processes. This session brings together groups with new results from isotope tracers (Th\, Pa\, Nd\, Hf\, Cd\, Fe\, etc.) in the hopes of revealing new developments in our understanding of chemical cycling of the oceans \n**OS036: Sources\, Sinks\, and Speciation of Marine Micronutrient Trace ElementsConveners: Jessica N Fitzsimmons (MIT) and Christopher T Hayes (Columbia University
) \nMarine primary production can be limited by the concentration of micronutrient trace metals such as Fe. Linking micronutrient supply to biology remains a challenge\, however\, because of a poor understanding of the marine distribution and cycling of these metals. The de-convolution of micronutrient biogeochemical cycles is aided by an investigation of their size partitioning/chemical speciation\, as well as the cycles of other metals (such as Al\, Th) that constrain individual parts of the micronutrient cycle. This session welcomes data from recent GEOTRACES cruises\, process studies\, or modeling efforts focused on understanding the distribution\, supply\, removal\, or chemical speciation of marine micronutrient trace elements.

Proxy development for paleoclimate and paleocean chemistry(co-hosted by Themes 10 and 13)Co-convenors: Ann Russell (University of California at Davis) – Pamela Martin (University of Chicago) – Bärbel Hönisch (Lamont-Doherty Earth Observatory)Development of geochemical proxies for reconstructing past climatic and ocean chemical conditions is a key component of paleoclimate and paleoceanographic research and essential for gleaning insight into the Earth’s future from its history. Archives of paleoenvironmental information include both biogenic and authigenic precipitates and isolating an environmental signal can be convoluted by post-depositional overgrowths. Covariation of environmental parameters can also make it difficult to calibrate the response of a proxy to a single environmental parameter. In deep time\, additional complications can arise when the possible controls over proxy relationships are less constrained and different_from_modern seawater chemistry may change proxy relationships from the conditions under which the proxy was calibrated.This session seeks to share progress on identifying the primary geochemical mechanisms and environmental controls over marine proxies\, as well as approaches and tools for addressing post- depositional alteration. We welcome contributions focused on the geochemistry of proxies from carbonates\, diatoms\, organic material\, as well as bulk sediments and authigenic precipitates. We encourage analytic method development and specifically contributions that go beyond empirical correlations between ocean parameters and proxy signals\, which may improve the quality of proxy applications by delving into the mechanistic basis for the relationship.Keynote speaker: TBA \n*10c. Past and future changes in ocean circulationCo-convenors: Eric Galbraith (GEOTOP-McGill University) – Laura Robinson (University of Bristol)Despite decades of research\, the large-scale drivers of deep-ocean circulation – and its susceptibility to change – remain poorly understood. Ocean mixing\, especially vertical mixing\, is of critical importance to this circulation\, but is difficult to observe in the modern ocean. Paleoceanographic records offer great potential in constraining past changes in ocean circulation\, which can help reveal natural variability of ocean mixing\, while ocean models can provide insight into mechanisms\, constrained by present-day observations. Together\, these approaches help to predict the biogeochemical impacts of future changes in ocean circulation. This session aims to bring together geochemical observations and theory that can shed light on ocean mixing and its impacts on ocean circulation\, and gas and nutrient cycling in the past\, present and future. We invite contributions that can constrain or quantify deep ocean circulation on any timescale\, and particularly encourage contributions that bear on vertical mixing in the ocean. We also welcome theoretical and modeling contributions that address the role of ocean circulation on biogeochemistry\, or that help to interpret geochemical observations.Keynote speaker: TBA \n*11a. Biogeochemical cycling of aerosols and their effects in the evolving Earth’s climate(co-hosted by Themes 11 and 10)Co-conveners: Nicholas Meskhidze (North Carolina State University) – Ina Tegen (Institute for Tropospheric Research\, Leipzig\, Germany)Climate projections remain an important scientific goal for the earth science community. A large fraction of the uncertainty in predicting climate change lies in the uncertainties associated with feedbacks in the carbon cycle and aerosol forcing. These feedbacks are the result of land-atmosphere-ocean natural and anthropogenic interactions. Understanding those interactions is of great importance for characterizing possible future changes in the evolving Earth. While aerosols are a source of micronutrients (iron\, phosphorus\, nitrogen) for the ecosystems\, the emission and transformation processes of many aerosols (e.g. desert dust or secondary organic aerosols of biogenic sources) can themselves be influenced by biogeochemical processes. We invite submissions on lab/field measurements\, remote sensing\, and modeling that lead to process-level understanding of biogeochemical land-atmosphere-ocean interactions. Interdisciplinary research on deposition of dust and volcanic particles\, heterogeneous chemical/photochemical transformation of aerosols\, and in-situ studies for the effects of aerosols on ocean/terrestrial biogeochemistry are welcome. The earth system models with aerosol deposition coupled to the land-ocean biogeochemistry are in their infancy. Until such models can reliably reproduce the effect of aerosol deposition on carbon cycle\, it will be problematic to estimate how changes in aerosol deposition over time might have affected the evolving climate of the Earth. \n*12b. Pa and Th distributions in the ocean: controlling mechanisms(co-hosted by Themes 12 and 13)Co-convenors: Abel Guihou (SUNY-Stony Brook) – Robert F Anderson (LDEO of Columbia University)231Pa and long-lived Th isotopes are naturally occurring radionuclides. Their potential to provide quantitative information of modern and past oceanographic processes (such as large scale ocean circulation and particle fluxes and dissolution) has been acknowledged for decades. However\, some uncertainties still remain regarding what actually controls their distribution in the ocean. This session invites contributions aimed to better understand these mechanisms such has new dissolved and particulate water column profiles\, new views on the distribution of these radionuclides onto particles from natural samples or from laboratory experiments as well as modeling studies.Keynote speaker: Michiel Rutgers van der Loeff (Alfred Wegener Institute for Polar and Marine Research) \n*12e. Present and past biogeochemical cycling of nutrients and metals in high latitude marine environments(co-hosted by Themes 12 and 16)Co-convenors: Dr. Laura Wehrmann (University of California Riverside\, USA) – Dr. Christian März (Newcastle University\, UK) This session targets the emerging field of biogeochemical research in Arctic and Antarctic environments\, with a focus on understanding the role of the high latitudes for global element cycles (C\, N\, P\, S\, Si\, transition metals) at present and in the past. We welcome contributions elucidating the cycling of these elements in the water column\, at the ice-sediment and sediment-water interface\, in shallow as well as in deeply buried marine sediments of high latitude environments. This session aims to gather scientists studying Arctic and Antarctic fjords\, estuaries and river mouths\, glacial and pro-glacial environments\, as well as associated continental shelves\, slopes\, and the deep oceans. Topics of particular interest include\, but are not limited to the (coupled) cycling of carbon\, sulphur\, phosphorus\, iron and manganese in Arctic and Antarctic sediments; the overprint of paleoclimate proxies by biogeochemical processes; the role of microbial processes in shaping the diagenetic characteristics of high latitude environments; biogeochemical interactions between glaciers and the coastal ocean; the role of high latitude environments for global biogeochemical cycles in the past. We especially encourage contributions that apply multidisciplinary approaches\, novel analytical techniques\, and computer modelling to natural samples and/or in laboratory experiments.Keynote speaker: Prof. Rob Raiswell (Emeritus)\, School of Earth and Environment\, University of Leeds\, UK \n*12g. Contribution of submarine groundwater discharge to oceanic chemical cycles(co-hosted by Themes 12 and 22)Co-convenors: Aaron Beck (Virginia Institute of Marine Science) – Richard Peterson (Coastal Carolina University)Submarine groundwater discharge (SGD) comprises all water transported by advection across the permeable sediment-water interface\, including both fresh groundwater and recirculated seawater. Biogeochemical reactions such as ion exchange\, dissolution and precipitation\, and metal redox cycling occur in the subsurface mixing zone of fresh and saline groundwaters (the “subterranean estuary”)\, resulting in brackish SGD that can be very different in composition from either of the original end-members. Further\, the advection of groundwater through the diagenetic zone can mobilize regenerated nutrients\, and serve as a transport pathway of these recycled nutrients back to the water column. A growing body of work demonstrates the importance of SGD and subterranean estuaries to marine budgets of nutrients\, radionuclides\, and trace elements. Understanding current SGD-driven chemical fluxes is critical for predicting how future changes in the hydrologic cycle\, coastal margins\, and anthropogenic factors may affect chemical cycling in the ocean. This session will explore the role of SGD and the subterranean estuary in controlling chemical fluxes between land and sea. We especially encourage studies that assess the ecological impact of these fluxes\, which is yet relatively unrepresented in this field. \n*13b. Geochemical proxies for past ocean circulationCo-convenors: Anton Eisenhauer (IFM-GEOMAR/Kiel) – Steven L. Goldstein (Lamont-Doherty Earth Observatory) – Ralph Schneider (Universität Kiel) The ocean circulation is an important aspect for the marine trace metal and nutrient cycling for the Present and in the Past. In particular\, ocean circulation interferes with the global carbon cycle influencing atmospheric pCO2 as well as long and short term climate change. In order to better understand present and past biogeochemical cycles it is most important to document and understand ocean dynamics on all time scales. Past changes in ocean circulation can only be reconstructed from geological archives\, among others\, through the application and interpretation of geochemical proxies. This session invites contributions addressing new developments and findings\, both experimental and theoretical\, on the application of geochemical proxies\, trace elements and isotopes to reconstruct past ocean dynamics.Keynote speaker: Gerald H. Haug (ETH Zürich)  \n*13d. GEOTRACES\, the international science programCo-convenors: Géraldine Sarthou (Université de Brest) – Kazuyo Tachikawa (CEREGE\, France) – Tina van De Flierdt (Imperial College\, London)Many trace elements are critical for marine life\, and affect the functioning of ocean ecosystems. On the other hand\, some trace elements and isotopes are used to track modern ocean processes\, and if they are recorded faithfully in marine archives\, they are powerful indicators of past changes. International science program GEOTRACES aims at identifying processes\, quantifying fluxes and establishing the sensitivity of the distribution of key trace elements and isotopes. We invite contributions that focus on fluxes and processes at ocean interfaces\, internal cycle of the trace elements and isotopes\, and development of proxies for past changes\, based on experimental and/or modelling approaches. Results from the recent GEOTRACES cruise are particularly welcome. \n*17e.The application of synchrotron X-ray techniques to study marine biogeochemical cyclesCo-convenors: Phoebe J. Lam (Woods Hole Oceanographic Institution) – Brandy M. Toner ( University of Minnesota – Twin Cities) – Benjamin S. Twining (Bigelow Laboratory for Ocean Sciences)Synchrotron X-ray techniques in the soft\, “tender”\, and hard x-ray energy ranges are increasingly applied to address questions in marine science. Applications have included two- and three-dimensional element-specific imaging at nanometer to micron scales to determine cell quotas and elemental distributions and function\, and spectroscopic analyses to determine the speciation\, provenance\, and bioavailability of key nutrients such as phosphorus and iron. We invite abstracts from researchers who are already applying synchrotron techniques to marine problems\, as well as those whose work in other areas of Earth science might be applicable to topics in marine biogeochemical cycling. For example\, poorly understood processes such as scavenging of trace metals in the ocean might be informed by studies of complexation of surface-adsorbed species onto model minerals and microorganisms. Similarly\, mechanisms of elemental substitution in inorganic and biominerals may change the stability and thus biogeochemical role of these minerals in the oceans. We envision a session enabling cross-fertilization of ideas between laboratory and field researchers\, and biologists and geochemists.Keynote speaker: Jay Brandes (Skidaway Institute of Oceanography) \n

DESCRIPTION:US GEOTRACES Arctic implementation workshopDates: 12-15 June 2012Location: National Science Foundation\, US.   \nThe US Arctic Implementation Plan is available to download.  \nAnnouncement \n US GEOTRACES will hold a workshop to define the scientific objectives of a cruise in the western Arctic Ocean\, tentatively planned for late summer 2015.  Investigators interested in conducting research as part of this cruise are invited to attend the workshop\, which will take place 13-15 June 2012 at the National Science Foundation.  No prior involvement in GEOTRACES is necessary to participate in this workshop. \n A framework for planning this cruise is provided in two reports from previous Arctic GEOTRACES planning workshops\, posted online at: (http://www.geotraces.org/libraries/documents/Arctic_Report.pdf) and at (http://www.usgeotraces.com/documents/arcticDOC/ArcticWorkshopRpt.pdf) . \nThe purpose of this workshop is to refine the research objectives for the cruise and to devise a strategy to meet those objectives.  Members of the US GEOTRACES Scientific Steering Committee (SSC) will participate in the workshop.  They will synthesize results from the deliberations and prepare a set of priorities to guide the submission (tentatively 15 February 2014) and evaluation of proposals.  The overriding criterion for establishing priorities is the degree to which an activity will enable US scientists to achieve the goals of GEOTRACES as defined in the Science Plan (http://www.geotraces.org/science/science-plan). \nThe Science Plan defines a number of key TEIs that must be measured on every section.  It also identifies a number of complementary parameters that would be desirable.  These include other TEIs that are of interest in their own right\, for example in illuminating specific processes of interest\, or parameters that may be critical for interpreting the distributions of key TEIs (e.g.\, circulation tracers).  The SSC will consider these factors when establishing priorities for the section. \nIn preparation for the workshop\, the SSC requests that those interested in participating submit a brief (one page maximum) statement of interest by 6 April 2012. Statements should (a) define the nature of the work to be done on the cruise\, and (b) justify the work in terms of GEOTRACES objectives.  Statements can be emailed (preferably as Word documents) to geotraces@ldeo.columbia.edu>.  Statements will be posted on the US GEOTRACES web site unless the author requests that they be held in confidence. \nAlthough no prior involvement in GEOTRACES is necessary to participate in the Arctic section\, new investigators who have not participated in the GEOTRACES intercalibration exercise are obliged to follow the GEOTRACES policy for new investigators.  This involves analysis of GEOTRACES reference standards\, where applicable\, or collection of duplicate samples for analysis by labs that have already demonstrated acceptable performance in the GEOTRACES intercalibration.  This policy will be explained at the workshop. \nWorkshop travel expenses will be subsidized by the US GEOTRACES project office.  The project office budget will cover full travel expenses for approximately 45 participants.  However\, the SSC prefers to limit the level of travel reimbursement rather than limit the number of participants.  Therefore\, the level of reimbursement may have to be limited if the number of participants exceeds approximately 45. \n Questions about Arctic planning can be directed to David Kadko .  \nQuestions about US GEOTRACES travel can be directed to the US GEOTRACES Project Office at .

SUMMARY:An Interdisciplinary Assessment of Climate Change Impacts on the Arctic Ocean
DESCRIPTION:An Interdisciplinary Assessment of Climate Change Impacts on the Arctic OceanA Peter Wall Institute for Advanced Studies Exploratory WorkshopDates: 2-4 May 2012Location: University of British Columbia\, Vancouver BC \nFor further information: http://www.arctic-climate-change.pwias.ubc.ca/ \nThe Report of the Workshop is available to download. \nOverview \nThe effects of global warming are most obvious in the Arctic\, both on land and at sea. On land\, ice sheets and glaciers are melting\, permafrost is thawing\, the flow of rivers is increasing and their chemical composition is changing.  In the Arctic Ocean\, sea ice is receding and the hydrography\, circulation\, chemistry and ecosystems are changing rapidly. Locally\, these changes affect the livelihood of northern communities. Globally\, they affect climate as a result of altered greenhouse gas emissions\, ocean circulation and heat transport. As these perturbations accelerate\, there is an increasing sense of urgency to document their extent and to understand their consequences.  This exploratory workshop assembled a group of Canadian and international Arctic experts with various backgrounds to foster inter-disciplinary collaborations and to initiate a large-scale research program investigating the biological\, chemical and physical responses of the Arctic Ocean to climate changes.  \nAgenda \nThe Agenda of the Workshop is available to download. \nList of Participants \nThe List of Participants is available to download. \nReport \nThe Report of the Workshop is available to download.
