However\, the knowledge on regional distributions and internal cycling of trace elements and their isotopes (TEIs) in seawaters in the NWPO is still limited. \n\n\n\nFor example\, mercury (Hg) cycling in the oceans has drawn extensive public concerns because of the production of methylmercury (MeHg) in the marine environments. The produced MeHg can then be biomagnified via food chain\, bioaccumulated to high concentrations in organisms at high trophic levels and pose great threat to human health. Some efforts have been made on investigating the distribution and cycling of Hg in the Pacific Ocean. East Asia is the largest source region for Hg. Large amounts of Hg were discharged into the ocean via riverine input and atmospheric deposition\, highlighting the importance of this region in Hg studies. However\, there is lack of studies on the distribution and cycling of Hg in the NWPO. Few mercury data following the GEOTRACES protocols were reported in this region and controlling processes and factors for Hg cycling in the NWPO are largely unknown. \n\n\n\nAs major GEOTRACES ocean interfaces\, exchange between atmosphere and surface water\, sediments and the overlying water column significantly influence the net sources and sinks for dissolved TEIs in seawater\, as well as the internal cycling of TEIs in the NWPO. However\, little is known about net supplies of TEIs from sediments and atmosphere as well as the key processes and key areas for the supplies in the NWPO. The marginal seas in the NWPO\, such as Bering Sea\, Sea of Okhotsk\, East China Sea\, and South China Sea\, receive significant amount of lithogenic and anthropogenic substances from fluvial input and submarine groundwater discharge. These marginal seas are also important source areas that supply trace elements to the NWPO\, which can highly influence TEIs cycling in open ocean. The major transport processes and fluxes for TEIs in each individual marginal sea remain to be explored. The major western boundary current of the NWPO\, the Kuroshio\, flows exactly through the region between the marginal seas and the NWPO\, passing by the eastern ends of Philippine and Taiwan and mixed with the seawater originated from the East and South China Seas\, then going northeastern direction to form the Kuroshio extension. The dynamic Kuroshio system not only links the NWPO and its marginal sea but also indicates the necessity for regional collaboration to fully understanding TEIs cycling in the oceanic region. \n\n\n\nAn Asia GEOTRACES Workshop\, organized by Ocean University of China\, will be held in Qingdao on December 8-10\, 2019. In this workshop\, we plan to invite GEOTRACES scientists in Asia as well as other regions to evaluate a full picture of the current status of the studies on the major sources/sinks and internal cycling processes of TEIs in seawater (emphasized on mercury) in the NWPO\, and to generate a future regional collaboration and action plan for Asia GEOTRACES. \n\n\n\nTopics \n\n\n\n1) Mercury in the NWPO (Part I) \n\n\n\nContributions of Asia marginal seas to mercury in the Pacific OceanMercury speciation and cycling in the NWPOMercury international inter-calibration and strengthening the capability of marine Hg analysis and study in the AsiaDiscussion on the Part II: Mercury international inter-calibration during the testing cruise via “Dongfanghong III”\n\n\n\n2) TEls fluxes and processes at ocean interfaces \n\n\n\nAtmospheric depositionContinental run-off (e.g. fluvial input and submarine groundwater discharge)Interaction between marginal seas and Kuroshio waterSediment-water boundary\n\n\n\nOrganizers \n\n\n\nJingling Ren\, Yanbin Li\, Qian Liu\, Jing Zhang\, Meixun Zhao \n\n\n\nVenue and Accommodation \n\n\n\nThe workshop will be held in Badaguan Hotel (Shanhaiguan Road 19\, Qingdao\, Shandong).

Eric Achterberg initiated the GEOTRACES seminar during his visit as part of the Helmholtz team. About 50 people attended the seminar in Moscow and some people listened to the presentation remotely in Sevastopol\, Kaliningrad\, and Arkhangelsk. The presentation aroused a great interest among the seminar participants. \n\n\n\nOrganizers \n\n\n\nProf. Dr. Eric Achterberg (SSC member)\, PhD Marina Kravchishina (SSC member) and Prof. Dr. Piotr Zavyalov (Corresponding Member of Russian Academy of Sciences (RAS)\, Shirshov Institute of Oceanology of RAS\, chairman of the regular academic council meeting). \n\n\n\nIntroduction \n\n\n\n12:00 (about 15 min) \n\n\n\nPiotr Zavyalov welcomed the colleagues of IO RAS and guests from other Institutes and Universities (Lomonosov Moscow State University\, Russian Federal Research Institute of Fisheries and Oceanography and etc). He then introduced Prof. Dr. Eric Achterberg (Chemical Oceanography GEOMAR\, Helmholtz Centre for Ocean Research Kiel and Christian-Albrechts University Kiel\, Germany\, member of the international GEOTRACES program) who initiated the GEOTRACES seminar. \n\n\n\nMarina Kravchishina reported about GEOTRACES activity in Russia and highlighted the main purposes of the study of the marine biogeochemical cycles of trace elements and their isotopes (TEIs) and the need for international collaboration. \n\n\n\nOpening Speech \n\n\n\n50 minutes talk \n\n\n\nProf. Dr. Eric Achterberg \n\n\n\nInternational GEOTRACES Programme: Observations across ocean gradients provide insights into biogeochemical cycles \n\n\n\nExperimental work in laboratories and at sea provides important detail on biogeochemical processes and (micro)-nutrient limitation of ocean productivity. Whilst forcing variables can be carefully manipulated in bottle and mesocosm experiments\, artefacts may occur due to exclusion of parts of plankton communities\, contamination and/or ´bottle´ effects. Biogeochemical process observations across biogeochemical gradients as part of section cruises form an elegant alternative. In this talk\, I will present examples of how cruises linked to the SOLAS and GEOTRACES programmes are providing excellent platforms for observations of changes in biogeochemical processes as a consequence of strong geochemical gradients. I will present geochemical gradients related to volcanic\, dust\, glacier and river inputs and their impacts on ocean biology. I will explore variations in nitrogen fixation\, (micro)-nutrient limitation of microbial communities\, and iron cycling related to changes in supply of (micro)-nutrients and oxygen. \n\n\n\nThe improved process understanding and quantification can be used for projections of biogeochemical processes in a future ocean. \n\n\n\nAbout 20 minutes – questions and discussion after the presentation. \n\n\n\nLunch \n\n\n\nRound Table \n\n\n\nAbout two hours. \n\n\n\nA very useful discussion on the TEIs clean sampling systems and analyses was organized after the seminar by Prof. Dr. Eric Achterberg (SSC member)\, PhD Marina Kravchishina (SSC member) and Dr. Ludmila Demina (Past SSC member). About 10 people took part in the discussion that interested in TEIs studying in seawater. \n\n\n\n  URL:https://www.geotraces.org/event/2nd-russian-geotraces-seminar/ LOCATION:Shirshov Institute of Oceanology\, Russian Academy of Sciences\, Moscow\, Russian Federation CATEGORIES:GEOTRACES Scientific Workshops END:VEVENT BEGIN:VEVENT DTSTART;VALUE=DATE:20200216 DTEND;VALUE=DATE:20200222 DTSTAMP:20260406T012947 CREATED:20191010T081347Z LAST-MODIFIED:20210726T112538Z UID:3277-1581811200-1582329599@www.geotraces.org SUMMARY:2020 Ocean Sciences Meeting  DESCRIPTION:2020 Ocean Sciences Meeting Dates: 16-21 February 2020Location: San Diego\, California\, USA. \n\n\n\nFor more information: https://www2.agu.org/ocean-sciences-meeting \n\n\n\nGEOTRACES and GEOTRACES related sessions: \n\n\n\nRevealing Biogeochemical Processes on Basin Scales through Ocean TransectsSession ID#: CT008https://agu.confex.com/agu/osm20/prelim.cgi/Session/84582 \n\n\n\nBiogeochemical processes that affect the cycling of trace elements and their isotopes\, as well as carbon\, macronutrients and other constituents\, are studied using two basic field strategies: sampling at a fixed station or regime to measure rates and examine specific processes\, or transects on up to basin scales. Each has its strengths and weaknesses\, but transects can gather a broad sweep of information on a relatively short time scale that can then be used to develop a more specific process-oriented approach. Indeed\, the GEOSECS program of the 1970’s used the transect approach\, and currently the GO-SHIP/Repeat Hydrography and international GEOTRACES programs feature long ocean transects. This session will highlight biogeochemical processes revealed on basin transects that affect trace constituents such as trace elements and isotopes\, as well as organic constituents\, including carbon and macronutrients. It will also focus on sampling and data analysis methods applied to sampling across basins\, and biogeochemical modeling studies that integrate data from long transects into their analyses. \n\n\n\nPrimary Chair: Gregory A Cutter\, Old Dominion University. \n\n\n\nCo-chairs: Phoebe J Lam\, University of California Santa Cruz;  Karen L Casciotti\, Stanford University; Rob Middag\, Royal Netherlands Institute for Sea Research. \n\n\n\nLinking the biology\, geochemistry\, and circulation of the Gulf of MexicoSession ID#: OB015https://agu.confex.com/agu/osm20/prelim.cgi/Session/84432 \n\n\n\nSession Description: \n\n\n\nThe Gulf of Mexico is a small\, dynamic marginal sea that supports a broad range of oceanographic environments\, including eutrophic coastal systems\, oligotrophic open ocean waters\, hydrocarbon-impacted waters and sediments\, and shelf waters that are susceptible to frequent harmful algal blooms. Large atmospheric\, riverine\, and submarine groundwater fluxes strongly influence the biogeochemistry of near-shore and open ocean waters\, yielding a high degree of spatial and temporal variability. Several recent studies have focused on characterizing the biogeochemistry of the Gulf of Mexico using a range of interdisciplinary approaches. Following on a successful 2018 OSM Town Hall led by GEOTRACES and OCB\, this session will bring together interested investigators to highlight new results from the Gulf and identify potential areas of common interest and collaborative opportunities to help inform future planning in GEOTRACES\, OCB\, and other relevant programs. We invite contributions that characterize the variability in the biology\, geochemistry\, and/or physical oceanography of the Gulf of Mexico\, and especially the linkages between them. Suggested contributions may include\, but are not limited to descriptions of water column and benthic geochemical distributions\, biogeochemical rate measurements\, characterizations of molecular ecology\, geochemical fluxes\, and descriptions of circulation that impact Gulf biogeochemical dynamics. \n\n\n\nPrimary Chair: Angela N Knapp\, Florida State University. \n\n\n\nCo-chairs: Alan M Shiller\, University of Southern Mississippi; Heather M Benway\, Woods Hole Oceanographic Inst.; Juan Carlos Herguera\, Center for Scientific Research and Higher Education at Ensenada. \n\n\n\nControls on trace metal biogeochemistry and physicochemical speciation in seawaterSession ID#: CT004https://agu.confex.com/agu/osm20/prelim.cgi/Session/85790 \n\n\n\nSession Description: \n\n\n\nTrace metals function as essential micronutrients and pollutants in the ocean. Organic complexation\, size partitioning\, and redox changes of trace elements can be mediated by biological processes including uptake\, regeneration\, cell lysis\, and organic ligand production. Additional processes influencing the production\, degradation\, and composition of organic matter also play an important role in controlling trace metal distributions\, and both vary across environments (e.g. estuaries\, open ocean\, air-sea-sediment interfaces\, hydrothermal systems). In turn\, resulting changes in bioavailability and cycling of trace elements governs the function and composition of marine phytoplankton communities. Recent efforts\, particularly within GEOTRACES\, have expanded the database of trace metal concentrations and physicochemical speciation. This session seeks to link our understanding of biology\, organic matter\, and trace metal chemistry from molecular to basin-wide scales\, from studies related to biologically-mediated transformations of trace elements to the wider processes controlling metal distributions\, size partitioning\, and fluxes. We welcome submissions highlighting how marine organisms influence the physicochemical speciation of trace elements in seawater\, and how changes in trace element chemistry impact the structure and function of marine ecosystems. In addition to observational\, experimental and modelling studies\, we also invite contributions on the production\, degradation\, and characterization of metal-binding compounds and colloids. \n\n\n\nPrimary Chair: Hannah Whitby\, IUEM Institut Universitaire Européen de la Mer. \n\n\n\nCo-chairs: Randelle M Bundy\, University of Washington; Jessica N Fitzsimmons\, Texas A & M University College Station; Andrea Koschinsky\, Jacobs University Bremen. \n\n\n\nBiogeochemical cycles in oxygen minimum zones: mechanisms\, drivers\, and changeSession ID#: CT001https://agu.confex.com/agu/osm20/prelim.cgi/Session/85226 \n\n\n\nSession Description: \n\n\n\nOxygen minimum zones in the coastal and open ocean are spatially expanding and intensifying\, with model projections showing continued O2 loss in the future. These regions play a fundamental role in the biogeochemical cycles of elements such as carbon\, nitrogen and sulfur as well as trace elements\, host microbial communities with diverse metabolic pathways\, and act as significant sources and sinks of nutrients and climatically relevant (greenhouse) gases. Yet\, significant questions on the nature\, drivers and variability of these processes remain. This session aims to build a comprehensive view of oxygen minimum zone biogeochemistry\, by inviting researchers who apply a variety of approaches to these problems\, from field and laboratory measurements\, to -omics based studies\, to observational synthesis and numerical models. Specifically\, we invite submissions investigating: (1) the distribution\, speciation and transformation of macronutrients (N\, P\, Si)\, trace metals (e.g. Mn\, Fe\, Co\, Ni\, Cu\, Zn\, Cd)\, redox-active elements (e.g. S\, Cr\, Mo\, I) and their isotopes; (2) microbial interactions and their impacts on biogeochemical cycles; (3) processes occurring in and around particle-associated microenvironments\, and (4) the physical drivers and variability of these processes. Studies assessing regional or global impacts with large/new datasets\, e.g. from international programs such as GEOTRACES\, and integrative approaches combining modeling\, field/laboratory measurements\, and/or microbial and molecular approaches are especially encouraged. \n\n\n\nPrimary Chair: David Janssen\, University of Bern. \n\n\n\nCo-chairs: Daniele Bianchi\, University of California Los Angeles; Thomas S Weber\, University of Rochester. \n\n\n\nCT003 – Chemical Speciation and Biogeochemistry in a Changing OceanSession ID#: CT003https://agu.confex.com/agu/osm20/prelim.cgi/Session/85778 \n\n\n\nSession Description: \n\n\n\nHow is seawater chemistry responding to global change processes\, and what are the consequences for marine ecosystems? How do advances in our understanding of chemical speciation give new mechanistic insight into biogeochemical processes? The thermodynamics of solution chemistry in addition to the distribution of trace metals and organic complexes along a gradient of particle sizes and ephemeral clusters are the focus of our session. Although solution thermodynamics is a relatively mature field\, there is an upsurge of research on both measurement and modelling of chemical speciation and an increasing focus on the assessment of uncertainties. This session will also explore interactions between solid and soluble species\, focusing on how recent developments examining the continuum between solid and dissolved (colloids\, nanoparticles\, etc.) alter our paradigm view of element cycling. The transport and reactivity of these ‘in-between’ species may differ from their fully dissolved or solid counterparts\, yet they are the most difficult to sample and observe. We invite submissions pertaining to the measurement and modelling of chemical speciation; assessment of modelling uncertainties; abiotic and biotic transformations from the solid to soluble phase and back again; reactions at the solid-solution interface; trace metal binding environments; sediment-seawater relationships; and interpretation of paleo records. \n\n\n\nPrimary Chair: David R Turner\, University of Gothenburg. \n\n\n\nCo-chairs: Veronique Oldham\, University of Delaware; Sylvia Sander\, IAEA; Emily R Estes\, WHOI. \n\n\n\nAutonomous observing systems for macronutrients and bioactive trace metals in coastal and open ocean settings: present status\, challenges and emerging technologiesSession ID#: IS003https://agu.confex.com/agu/osm20/prelim.cgi/Session/84800 \n\n\n\nSession Description: \n\n\n\nProgress and discovery in the understanding and modeling of biological productivity and species composition in the marine environment is limited by our ability to make macronutrient and bioactive trace metal measurements at relevant spatial and temporal scales. While significant progress has been made with the advent of UV and microfluidic nitrate sensors\, there are still few analytical systems for other important macronutrient species (P\, Si\, NH3) and virtually none for bioactive trace metals that can be deployed on the expanding array of platforms dedicated to long term unattended data gathering (i.e.\, moorings\, gliders\, profilers)\, particularly in oligotrophic surface ocean settings. \n\n\n\nThis session aims to: (1) highlight the latest developments in macronutrient and bioactive trace metal analytical methodologies with strong potential or demonstrated capabilities for unattended operation in coastal and open ocean settings and\, (2) serve as a forum to nurture collaborations among sensor developers and oceanographers with an engineering and analytical chemistry inclination. Contributions from all stages of development are encouraged including: remote samplers\, passive samplers\, reagent-based microfluidic analyzers including the use of novel chemical probes\, electrochemical methods\, optical sensors\, as well as the optimization\, calibration\, and field validation of emerging in situ technologies. \n\n\n\nPrimary Chair: Maxime Grand\, Moss Landing Marine Laboratories. \n\n\n\nCo-chairs: Andrew R Bowie\, University of Tasmania; Agathe Laes-Huon\, IFREMER; Alexander Beaton\, National Oceanography Center\, Soton. \n\n\n\nTowards BioGeoSCAPES: Exploring molecular drivers of ocean metabolism and biogeochemistrySession ID#: OB030https://agu.confex.com/agu/osm20/prelim.cgi/Session/84717 \n\n\n\nBioGeoSCAPES has been proposed as an idea for a new international coordinated research program to integrate knowledge on organism identity and physiology within frameworks of community ecology and global ocean biogeochemistry. It is envisioned that an improved\, predictive\, and quantitative understanding of ocean metabolism can be developed by combining detailed information on cell status\, biochemical processes\, and species interactions with intercalibrated measurements of nutrient fluxes and concentrations. We invite contributions describing research that can serve as inspiration for this nascent program. Appropriate abstracts could include: studies that integrate molecular and biogeochemical measurements\, including fluxes; research that places ‘omics observations (e.g.\, genomic\, transcriptomic\, proteomic\, metabolomic\, metallomic\, lipidomic\, etc.) within quantitative numerical modeling frameworks; or studies that scale from the cellular to the ecosystem level through integrated field measurements or mechanistic models of interactions. The aim of this session is to highlight research that combines informatics\, modeling\, and biogeochemical measurements across scales of time and space\, to test\, integrate\, connect\, and expand upon studies of ocean ecology and metabolism. \n\n\n\nPrimary Chair: Benjamin S Twining\, Bigelow Lab for Ocean Sciences. \n\n\n\nCo-chairs: Erin Marie Bertrand\, Dalhousie University; Martha Gledhill\, GEOMAR Helmholtz Centre for Ocean Research; Naomi Marcil Levine\, University of Southern California. \n\n\n\nThe role of micronutrient cycles in global-scale dynamicsSession ID#: CT010https://agu.confex.com/agu/osm20/prelim.cgi/Session/85400 \n\n\n\nSession Description: \n\n\n\nVia their fundamental control on ocean productivity and the biological carbon pump\, the cycling of nutrients plays an integral role in the dynamics of atmospheric CO2 and climate. In contrast to the ‘big three’- nitrogen\, phosphorus and silicon\, with their well characterised modern distributions and relatively stable inventories\, micronutrients\, such as iron\, remain relatively poorly observed and have the potential for rapid and profound changes in their inventories and biological availability in response to a host of poorly constrained processes. Micronutrients are currently the ‘wild card’ in both past and future carbon cycle and climate change\, prompting the need for improved understanding of their role in Earth system dynamics. We invite a broad range of submissions to provide insights into the pieces of the puzzle\, addressing boundary inputs and sinks\, exchanges between dissolved and solid phases\, interactions with organic compounds\, and their reciprocal interactions with microbial ecosystems. Submissions may include observations\, data synthesis or models\, and may address ocean nutrient cycling over a range of time-scales\, from past (paleo) through contemporary\, and/or in response to future global change. We particularly encourage new insights into the role of feedbacks and the role micronutrient cycles play in shaping global-scale dynamics. \n\n\n\nPrimary Chair: Andy Ridgwell\, University of California Riverside. \n\n\n\nCo-Chair: Alessandro Tagliabue\, University of Liverpool \n\n\n\nUnderstanding Rare Earth Element (REE) distributions and isotopic ratios and the mechanisms behind their use as tracers of (paleo)oceanic processesSession ID#: CT011https://agu.confex.com/agu/osm20/prelim.cgi/Session/84457 \n\n\n\nAnalytical advances have enabled a significant increase of environmental REE abundance and isotopic (e.g. Nd\, Ce) data. These elements are increasingly recognized as promising tracers for elucidating past and present natural and man-made processes in a variety of aquatic environments. However\, in spite of this growth in observations\, our understanding of the mechanisms\, capabilities and limitations of geochemical proxies based on REE abundances and isotopic ratios remains incomplete. We therefore invite presentations of field\, laboratory\, or modeling studies of REEs and related isotope systems aimed specifically at exploring mechanistic connections between their geochemical behavior and observed distributions in marine and terrestrial waters and sediments. Of particular interest are investigations linking REE abundance distributions to Nd or Ce isotopic ratios; validating the use of REEs as proxies of paleoceanographic processes; and addressing REE fractionation and source-to-sink transport on a global scale and at “geochemical hotspots” like estuaries\, hydrothermal vents\, nepheloid layers etc. Presentations that merely contribute TEI distribution data will be given lower priority. We especially encourage submissions from students and early-career scientists. \n\n\n\nPrimary Chair: Brian A Haley\, Oregon State University \n\n\n\nCo-chairs: Torben Stichel\, Alfred Wegener Institute Helmholtz-Center for Polar and Marine Research Bremerhaven; Johan Schijf\, University of Maryland Center for Environmental Science; Vanessa Hatje\, Universidade Federal da Bahia.

Other compartments of the earth system\, and related societal\, ecosystem and human health impact studies are welcome as well. Combined mercury and POPs as well as coupled observation and modelling approaches are especially welcome. The main objectives of this special session are to further the understanding of the sources and fluxes; the quantification and assessment of the processes; mechanisms driving transfer through the marine trophic web; biogeochemical modeling; effects of climate change and changed emissions scenarios; scenarios of mitigation and adaptation to mercury and POP’s pollution\, and impacts on society\, ecosystem and human health. \n\n\n\n*OS3.6 Impacts of anthropogenic pollution on ocean biogeochemistryCamille Richon\, Lars-Eric Heimbürger-Boavida\, Charlotte Laufkötter\, Susan Little \n\n\n\nhttps://meetingorganizer.copernicus.org/EGU2020/session/36174 \n\n\n\nMarine anthropogenic pollution is increasingly recognized as a serious issue of global concern with substantial risks for marine ecosystems\, fisheries\, and food supply to people. Plastic and chemical contaminants are spread on a planetary scale\, and may have devastating impacts on marine ecosystems. Yet\, they remain poorly studied and much is yet to learn about how plastic and chemical contamination impacts marine nutrient cycles and the lower food chain. In this session\, we invite contributions from experimentalists and modellers trying to understand the impacts of plastics as well as chemical contaminants on the biogeochemistry of the oceans. The objective of this session is to share the current research on how the multiple sources of anthropogenic pollution impact marine biogeochemical cycles\, such as pollutant leaching from plastics\, plastic ingestion by marine animals\, and direct contamination of the water by contaminated rivers\, aerosols\, or submarine groundwater. The session would welcome all techniques\, including direct measurements of contaminant fluxes\, isotopic or other approaches to tracing contamination\, modelling\, experimental incubations with contaminants\, mesocosm studies and toxicity assessments. We particularly encourage contributions regarding the quantification of sources and fluxes of contaminants to the marine environment\, and the effects of this contamination (toxicity from chemical contaminants such as heavy metals or PCBs\, effects of plastic ingestion on zooplankton…). \n\n\n\n*BG1.5 Mercury cycling in the environment – sources\, processes\, impacts\, and archives from local to global scalesan G. Wiederhold\, Sofi Jonsson\, Martin Jiskra\, Sophia Hansson \n\n\n\nhttps://meetingorganizer.copernicus.org/EGU2020/session/35204 \n\n\n\nMercury (Hg) is a toxic global pollutant of great environmental concern. The UNEP Minamata convention on mercury\, a legally-binding international treaty aiming to reduce negative impacts of Hg on the environment\, has entered into force in 2017. Anthropogenic activities have altered the global Hg cycle to a great extent and many ecosystems are threatened by exposure to elevated levels of Hg and its different species. For instance\, neurotoxic and bioaccumulating methyl-Hg is formed under the influence of anaerobic microorganisms in a variety of natural systems but the controls on this key process are still far from being understood. Further active Hg research areas include exchange processes at the atmosphere-soil-plant interface and their importance for understanding atmospheric Hg deposition\, the behavior and long-term fate of Hg at contaminated sites\, as well as global cycling models assessing the evolution of historic Hg fluxes from different natural and anthropogenic sources. In the past few years\, a number of novel research tools based on microbiological\, spectroscopic\, isotopic\, and modelling techniques have been developed to improve our understanding of Hg cycling in the environment. This session presents new contributions on present-day Hg cycling in the environment using field-based\, experimental\, and/or modelling approaches on local to global scales\, as well as contributions focusing on long- and short-term reconstruction of Hg as a pollutant over time using natural archives such as ice-cores\, tree-rings\, lake sediments and peat bogs. We particularly welcome research addressing the effects of the implementation of the Minamata convention on mercury levels in the environment and new approaches to assess its effectiveness. \n\n\n\n*BG4.5 The impact of anthropogenic sediment reworking on the seafloorSebastiaan van de Velde\, Pere Masqué and Sarah Paradis \n\n\n\nhttps://meetingorganizer.copernicus.org/EGU2020/session/35228 \n\n\n\nThe human imprint on the marine realm has rapidly increased during the last century\, leaving no area unaffected by human activities. Bottom trawl fishing intensity has boomed since the 1950s\, while at the same time dredging activities in coastal zones have intensified to maintain navigable waterways\, reclaim land\, construct wind farms or counteract coastal erosion. Off-shore drilling platforms have been constructed around the world\, and more recently\, deep-sea mining has become an attractive avenue for mineral extraction. All of these economic activities physically perturb the seabed\, and are expected to have a strong effect on the natural biological\, geochemical and physical dynamics of the ocean. However\, very little is understood about the short-term and long-term impact of these anthropogenic physical disturbances. \n\n\n\nThis session aims to create a multidisciplinary discussion on the impact and potential remediation of diverse anthropogenic alterations on the seafloor\, and invites contributions ranging from marine ecology over physical oceanography and biogeochemistry\, be it observational\, theoretical or experimental. \n\n\n\n*CL5.4 Challenges and opportunities arising from palaeo-data compilationsNikita Kaushal\, Laia Comas-Bru\, Franziska Lechleitner and Sophie Warken \n\n\n\nhttps://meetingorganizer.copernicus.org/EGU2020/session/36725 \n\n\n\nThe number of past climatic and/or ecological data generated from a range of distinct proxies and natural archives is continuously growing. Hence\, significant advances in palaeoclimate research can now be made using large-scale compilations. Establishing such large-scale databases reveal supra-regional and global spatial and temporal patterns in palaeoclimate conditions that are not possible with single records. This session aims at presenting current advances in palaeoclimate and palaeoecology based on local- to global-scale syntheses. Bringing together palaeoclimate databases with observational and/or climate modelling outputs is crucial for improving our understanding of past climate conditions\, to identify signal and noise components and their temporal dynamics\, and to gain insight into the quality of data-model comparisons. We therefore aim at bridging the gap between data generation\, earth system modeling and data assimilation studies. We encourage submissions on data compilations\, cross-comparison and modelling studies utilizing data repositories and databases (e.g.\, NEOTOMA\, SISAL\, PAGES2k\, ACER\, EPD).

It is an invitation-only meeting with a maximum attendance of 70. \n\n\n\nBackground\n\n\n\nUS GEOTRACES will hold a workshop 6 – 8 May 2020 at Old Dominion University to coordinate the scientific objectives and supporting logistics for a section to run from Tahiti to Amundsen Sea to the Chilean shelf (GEOTRACES Section GP17). Because of logistics issues this section would involve two separate research cruises\, tentatively planned for late 2021 and early 2022. Principal investigators interested in conducting research as part of one or both of these cruises are invited to attend a project planning workshop in Norfolk\, VA (details to follow). No prior involvement in GEOTRACES is necessary to participate. \n\n\n\nAn essential goal of this workshop is to supply potential participants and collaborators with all the pertinent details on\, and science behind\, the proposed cruises so that they can write successful proposals and therefore make the collaborative GP17 cruises a success. Workshop participants will have an opportunity to present their anticipated research contributions for the section in very brief advocacy talks. \n\n\n\nAnnouncement\n\n\n\nPlease click here to download the announcement.

In the last decade\, the International GEOTRACES Program has facilitated rapid progress in this area\, providing a wealth of data\, answers and new questions for our understanding of past and present ocean TEI cycling. In this session\, we aim to bring together studies from a range of disciplines\, over a range of scales\, that aim to address current questions in marine biogeochemical cycling. We invite submissions concerning any aspects of trace element chemistry and biogeochemistry in the oceans\, and encourage submissions presenting process studies or making use of large-scale concentration distributions or modeling of TEIs or their isotopes to provide new insights. Given the Hawaiian location of Goldschmidt in 2020\, and the recent sharp focus on the importance of East Pacific Rise and Loihi as TEI sources\, we especially encourage submissions dealing with the biogeochemistry of both near and far-field hydrothermal activity. We also encourage studies which focus on rates\, abiotic/biotic particle scavenging\, trace-metal speciation\, redox and isotope cycling\, organic ligand metal interactions\, and boundary exchange (redox\, atmosphere\, sediments\, hydrothermal\, rivers)\, or those that aim to use trace element isotope systems (e.g. Ba\, Si\, Zn\, Cd\, Cr\, Ni) as redox or productivity paleoproxies.

Modern oceanographic observations and modeling studies are making great advances in understanding MOC dynamics\, predictability\, and connections to Earth’s systems over seasonal to decadal periods. Meanwhile\, paleoclimate observations and modeling studies have highlighted the close link between changes in the climate system and variations in the structure and/or magnitude of MOC over multi-decadal to tectonic timescales. Much remains to be understood about the interplay between MOC changes and the cryosphere\, atmosphere\, and ocean biogeochemistry\, as well as mechanisms driving past\, present and future MOC variations. Modern and Paleo approaches are complementary and together bring new insights into MOC dynamics and predictability under future climate conditions. This session welcomes theoretical\, modeling\, and observation-based studies that investigate the nature\, stability and sensitivity of the MOC to external forcing and internal feedbacks across seasonal-to-tectonic timescales. \n\n\n\nPrimary ConvenersKelly H KilbourneUniversity of Maryland Center for Environmental Science Chesapeake Biological Lab \n\n\n\nConvenersFeng HeUniversity of Wisconsin-MadisonXu ZhangLanzhou UniversityJulia GottschalkLamont-Doherty Earth Observatory\, Columbia University of the City of New York URL:https://www.geotraces.org/event/agu-fall-meeting/ LOCATION:Virtual Meeting\, VA CATEGORIES:GEOTRACES Relevant Special Sessions END:VEVENT BEGIN:VEVENT DTSTART;VALUE=DATE:20210111 DTEND;VALUE=DATE:20210115 DTSTAMP:20260406T012947 CREATED:20200304T104602Z LAST-MODIFIED:20210726T122418Z UID:5743-1610323200-1610668799@www.geotraces.org SUMMARY:Fifth Xiamen Symposium on Marine Environmental Sciences (XMAS-V) DESCRIPTION:The Fifth Xiamen Symposium on Marine Environmental Sciences (XMAS-V) will be held from 11th to 14th January\, 2021. \n\n\n\nNOTE: Due to the coronavirus pandemic\, XMAS-V will be hosted online to support our community by fostering scientific communication.

However\, organisers plan to meet in Palma in 2023. \n\n\n\nEvent website: https://www.aslo.org/2021-virtual-meeting/ \n\n\n\nGEOTRACES and GEOTRACES related sessions:\n\n\n\n*SS63 Towards a mechanistic understanding of metal-microbe interactions in the Oceans\n\n\n\nMartha Gledhill\, GEOMAR Helmholtz Center for Ocean ResearchYeala Shaked\, Interuniversity Institute for Marine Sciences & The Fredy and Nadine Herrmann Institute of Earth Sciences\, Hebrew University of Jerusalem\, JerusalemIngrid Obernosterer\, Microbial Oceanography Laboratory(LOMIC)\, CNRS-Sorbonne University \n\n\n\nTrace metals are essential for life\, catalysing key cellular reactions which then govern patterns of ocean fertility and biodiversity. Fundamental in this regard are the ways in which ocean microbes acquire essential metals and how biological activity is affected by metal availability. Diverse microbial community members can compete for this scarce resource\, and trace-metal related metabolic functions can also be partitioned among taxa and benefit the whole population. Defining these interactions is critical for understanding the relationship between metabolic rates and elemental cycles in the ocean. Developments in this field are being led by advances in analytical chemistry\, nanotechnology\, molecular biology\, and bioinformatics\, as well as the expansion of ‘omics’-related observations of in-situ microbial communities\, and within the context of high resolution geochemical such as obtained as part the international GEOTRACES program. In this session we invite contributions that bring together insights from these different disciplines to better understand how microbial activity\, diversity and ecology is shaped by interactions with trace metals over different space and time scales. By linking across disciplines\, there is the potential to develop the mechanistic understanding required to inform the ecological and biogeochemical models we rely on for testing hypotheses and projecting the impacts of ocean change that will result from the impending BioGeoScapes program. We are specifically interested in contributions that address (i) metal uptake and interactions between microbes for metal resources\, (ii) how microbes adapt their physiology to metal scarcity and varied supply\, and (iii) how trace metals shape microbial activity and diversity in the ocean. \n\n\n\n*SS03 Distribution and impacts of ocean nutrient limitation\n\n\n\nThomas Browning\, GEOMAR Helmholtz Centre for Ocean Research KielMark Moore\, University of SouthamptonErin Bertrand\, Dalhousie UniversityAlessandro Tagliabue\, University of Liverpool \n\n\n\nNutrient limitation constrains primary production throughout the global ocean and regulates its responses to climate change. A broadscale picture of nutrient limitation in the current ocean has emerged\, with nitrogen limitation revailing in the stratified subtropical gyres and iron limitation in open ocean and some coastal upwelling regions. However\, new research is rapidly adding important detail to this simple picture. Evidence continues to accumulate for co-limitation between these and other nutrients\, including additional trace elements and vitamins. Such (co-)limitations are likely set by nutrient supply and removal mechanisms to and from the surface ocean\, phytoplankton elemental stoichiometry\, as well as microbial interactions within communities that are simultaneously under the influence of multiple additional abiotic (light\, temperature) and biotic (grazing\, viral lysis) controls. To understand this complexity\, new approaches ranging from advances in ‘-omics’ capabilities\, coordinated cruise programmes and autonomous platform observations\, through to alternative mathematic constructions of nutrient limited growth rates\, are being utilized. Such advances are urgently needed to better understand the drivers and impacts of oceanic nutrient limitation\, as well as meeting the needs of testing and improving Earth System Model simulations projecting the impacts of climate change. This session invites contributions utilizing in situ\, experimental\, and modelling approaches that represent new advances in understanding oceanic nutrient limitation. These could range from those describing the basic distribution and identity of limiting nutrients for diverse microbial groups to understanding the mechanisms\, impacts\, and future development of nutrient limitation in the ocean. \n\n\n\nThe full session list of sessions is available at: https://www.aslo.org/2021-virtual-meeting/session-list/ URL:https://www.geotraces.org/event/aslo-2021-aquatic-sciences-meeting/ LOCATION:Virtual Meeting\, VA CATEGORIES:GEOTRACES Relevant Special Sessions ATTACH;FMTTYPE=image/png:https://www.geotraces.org/wp-content/uploads/2021/02/Screenshot-2021-02-16-at-15.33.05.png END:VEVENT BEGIN:VEVENT DTSTART;VALUE=DATE:20210704 DTEND;VALUE=DATE:20210710 DTSTAMP:20260406T012947 CREATED:20210119T092952Z LAST-MODIFIED:20210726T122748Z UID:11144-1625356800-1625875199@www.geotraces.org SUMMARY:Virtual Goldschmidt 2021 DESCRIPTION:Goldschmidt is the foremost annual\, international conference on geochemistry and related subjects\, organized by the Geochemical Society and the European Association of Geochemistry. Given the exceptional circumstances due to the current Covid-19 pandemic\, the Goldschmidt2021 Conference will be an online meeting. \n\n\n\nGEOTRACES session: \n\n\n\n13a. Marine biogeochemistry: Particle fluxes and dissolved trace element cycling from source to sink \n\n\n\nConveners: Adi Torfstein\, Hebrew University of JerusalemPhoebe Lam\, University of California\, Santa CruzWilliam B Homoky\, University of LeedsErin Black\, Lamont-Doherty Earth ObservatoryAmber Annett\, University of SouthamptonChristopher T Hayes\, University of Southern Mississippi \n\n\n\nProvisional keynote:Claudia Benitez-Nelson\, University of South Carolina \n\n\n\nThe compositions of seawater and marine particulate material\, and their temporal and spatial fluxes and exchange\, play a pivotal role in modulating the biological pump and atmospheric CO2 uptake\, as well as various biogeochemical processes in the oceans. Determination of the inputs\, settling fluxes\, remineralization rates\, chemical scavenging and the linkage of particles to seawater composition and marine productivity\, are therefore critical for a full understanding of marine biogeochemical cycles and their impact on global climate. \n\n\n\nHere we seek contributions on the following non-exclusive topics: (1) new methodologies for determination of trace element concentrations\, isotopic compositions\, or particle flux rates\, (2) new approaches to characterize particle compositions\, including across size classes\, mineralogical phases or different environments\, or (3) the interactions between particles and dissolved distributions. We encourage submissions of multi-disciplinary studies\, such as GEOTRACES or other programs\, including applications of radionuclides\, experimental and analytical isotope geochemistry\, modeling\, and trace element partitioning between solid\, colloidal and dissolved phases. We focus on studies that describe processes in the modern oceans but submissions discussing paleoceanographic conditions are welcome. We further seek studies that focus on the interplay between external sources (e.g.\, dust\, rivers\, margins)\, surface productivity and marine particulate and dissolved compositions and fluxes.

DESCRIPTION:Location: Southern New Hampshire University\, Manchester\, NH\, US\n\n\n\nThis conference has been deferred to 2023 due to the ongoing impact of the COVID-19 pandemic. Please check back soon for the 2023 schedule.  \n\n\n\nGRC: Chemical Tracers in the Sea\n\n\n\nChemical tracers integrate time scales\, and source and transformation histories and have thus played a crucial role in oceanography. For this meeting\, we hope to focus on the development\, verification and application of chemical tracers of ocean chemistry\, biology and physics in the present and past\, with an eye toward predicting the future. Processes of interest could include the changing circulation and ventilation of the oceans\, the biological carbon pump including the sedimentary sink\, major chemical inputs into the ocean\, and internal transformations that impact the cycling of elements including rates. Talks will focus on the development of tracers including stable and radioactive isotopes\, organic and inorganic molecules\, analytical advances and the application of these tracers to improve our understanding of the “anthropocene”-\, holocene-\, and paleo-ocean. \n\n\n\nThe 2019 GRC will be preceded by a Gordon Research Seminar (GRS) in Chemical Oceanography that is open to graduate students and postdocs in Chemical Oceanography and related fields. The GRS provides a forum for early career researchers to present research results\, promote networking\, and to conduct career building discussions within a peer-to-peer setting. \n\n\n\nFor further information Gordon Research Seminar (GRS): https://www.grc.org/chemical-oceanography-grs-conference/2021/For further information Gordon Research Conference (GRC): https://www.grc.org/chemical-oceanography-conference/2021/ URL:https://www.geotraces.org/event/2021-gordon-research-conference-grc-and-seminar-grs-on-chemical-oceanography/ LOCATION:Southern New Hampshire University\, 2500 North River Road\, Manchester\, NH\, United States CATEGORIES:GEOTRACES Relevant Workshop END:VEVENT BEGIN:VEVENT DTSTART;VALUE=DATE:20210726 DTEND;VALUE=DATE:20210731 DTSTAMP:20260406T012947 CREATED:20201109T094353Z LAST-MODIFIED:20210726T122825Z UID:9640-1627257600-1627689599@www.geotraces.org SUMMARY:Iron at the Air-Sea Interface Workshop DESCRIPTION:Asheville\, NC\, USAWorkshop web site: https://zzqvaay3twhzlhnmvpvdvq-on.drv.tw/Web/Iron_Workshop/\n\n\n\nWorkshop co-sponsored by GEOTRACES and SOLAS! \n\n\n\nThe motivation for the workshop: Aerosol labile iron (LFe)\, the fraction of total aerosol iron that contributes to the dissolved Fe (DFe) inventory of the ocean\, is a crucial source of the micronutrient Fe to the remote marine environment. Current models for the ocean biogeochemical cycling of Fe assume that after deposition to the surface ocean\, all aerosol-LFe gets chelated by “free” marine organic ligands and gets converted to DFe. Yet laboratory studies and numerical simulations have shown that after deposition to the ocean only a small fraction of LFe may be chelated by marine organic ligands and enter the DFe pool. This happens because the free ligand concentration in the dust-affected region of the ocean gets quickly exhausted and the short lifetime of inorganic LFe in seawater does not allow for replenishment of organic ligands by the surface ocean vertical mixing and/or biological production and release. The efficiency of LFe to DFe conversion is one of the major unknowns for the global biogeochemical cycling of Fe. \n\n\n\nThis workshop is dedicated to an improved understanding of how does bioaccessible LFe move across the ocean-atmosphere interface and become bioavailable for uptake in the ocean at scales important for ocean ecosystems and the carbon cycle. \n\n\n\nGoals and expected outcomes of the workshop: 1) A white paper that will provide a workshop assessment report based on the consensus reached by diverse researchers from the oceanographic and atmospheric science communities with backgrounds in the laboratory and in situ measurements\, modeling\, and remote sensing\, and 2) a breakout session at AGU 2021 fall meeting to disseminate the workshop findings to the wider research community interested in the global biogeochemical cycling of iron. \n\n\n\nThe registration for the Iron Workshop is open until June 25\, 2021:https://zzqvaay3twhzlhnmvpvdvq-on.drv.tw/Web/Iron_Workshop/register.html \n\n\n\nFor further information on the registration fee\, agenda and logistics for this workshop please go to the workshop web page: https://zzqvaay3twhzlhnmvpvdvq-on.drv.tw/Web/Iron_Workshop/ \n\n\n\nFor questions regarding the workshop please contact Nicholas Meskhidze (NC State University) or Bill Landing (Florida State University).
