Our understanding of the rates and mechanisms of trace element and isotope (TEI) input\, biogeochemical cycling\, and removal is improved by multi-tracer data from basin-wide research cruises\, data from more focused process studies\, and synthesis and modeling of these data. In addition to contributions in these topical areas\, we particularly encourage submissions that integrate multiple tracers or isotope systems to provide constraints on biogeochemical processes in the oceans and that highlight the benefits of multi-proxy approaches. \n\n\n\n\n\n*Coastal\, Shelf\, and Island Mass Effects on Trace Element Biogeochemistry in the OceanWednesday\, 25 February 2026\, 8h30 – 10h00 (local time)\, Hall 4\, eLightning Theater 2 (SEC) Poster session on Wednesday\, 25 February 2026 \n\n\n\nCo-convenersDavid González-Santana\, IOCAG Universidad de Las Palmas de Gran CanariaAridane G. González\, IOCAG. Universidad de Las Palmas de Gran CanariaEmilie Le Roy\, IUEM Institut Universitaire Européen de la MerGabriel Dulaquais\, IUEM Institut Universitaire Européen de la Mer \n\n\n\nDescriptionThe marine biogeochemical cycles of trace elements\, their stable isotopes compositions and organic binding ligands are affected by the island mass effects. With terrigenous\, shelf and even glaciogenic inputs\, islands are natural laboratories for studying the importance of lateral fluxes of trace elements\, their impact on the physico-chemical processes and associated biological responses. This session aims to bring together researchers from diverse fields to discuss the latest findings on the biogeochemical processes occurring in the ocean and related to the island and shelf effects\, from the coast to the open ocean. The aim is to improve our knowledge\, identify biogeochemical impacts\, and characterise physico-chemical speciation of metals and redox chemistry. We welcome research studies and experiments focusing on processes affecting trace metal chemistry\, the nutrient cycle and organic ligands. \n\n\n\n\n\n*Mercury in Polar Waters: Sources\, Transformations\, and Bioaccumulation in Food WebsPoster session: Tuesday\, 24 February 2026\, 16:00 – 18:00 (local time)\, Hall 4 (Poster Hall) (SEC) \n\n\n\nCo-convenersEmily Seelen\, University of Alaska FairbanksMarissa Despins\, University of California Santa CruzStephen Kohler\, Norwegian University of Science and TechnologyMarissa Despins\, University of California Santa Cruz \n\n\n\nDescriptionHigh latitude environments are undergoing profound changes driven by climate warming. The impact of this change–sea ice loss\, permafrost thaw\, and shifting ocean circulation–is expected to alter the concentration and distribution of mercury (Hg) in polar marine waters. While models indicate that Hg concentrations will rise in the Arctic under current emission climate scenarios\, the processes influencing Hg mobility and speciation remain poorly understood\, especially in the Antarctic\, where data is even more limited. To accurately model the fate of Hg in a warming climate and risk for human exposure\, it is imperative that we understand the mechanisms governing Hg cycling\, particularly methylation and demethylation pathways\, which still remain elusive. This session invites contributions that explore the biogeochemical cycling of Hg in both the Arctic and Antarctic\, with a focus on the release and delivery of Hg species to coastal zones\, processes that influence Hg transformations\, and bioaccumulation in marine food webs. Interdisciplinary perspectives that incorporate Indigenous knowledge and community-based monitoring are also encouraged\, as are studies addressing the vulnerability of subsistence-dependent communities to changing Hg exposure. \n\n\n\n\n\n*Revising Ocean Silicon Cycle: Pathways\, Stoichiometry and Climate-Carbon Feedback in the AnthropocenePoster session: Monday\, 23 February 2026 \n\n\n\nCo-convenersDiksha SharmaHaimanti Biswas\, CSIR-National Institute of OceanographyDamien Cardinal\, Sorbonne UniversitéShaily Rahman\, University of Colorado Boulder \n\n\n\nDescriptionSilicon (Si)\, the second most abundant element in Earth’s crust\, is an essential nutrient for marine organisms (phytoplankton\, sponges\, radiolarians) and plays crucial roles in marine carbon cycling and ecosystems and\, atmospheric CO2 inventory. The ocean receives Si from different sources\, including continental erosion (riverine and groundwater discharge\, glacial meltwaters…)\, sedimentary recycling (reverse weathering\, diagenesis…)\, hydrothermal input\, and atmospheric deposition. However\, anthropogenic activities significantly alter Si supply to the ocean: damming restricts the riverine input of Si\, while climate-induced ocean stratification limits vertical mixing\, curtailing Si supply to surface waters. Contrarily\, increasing nitrogen (N) and phosphorus (P) inputs to the coastal areas are disrupting the Redfieldian Si:N:P stoichiometry\, causing a regional shift from siliceous to non-siliceous species\, impacting carbon export and trophic dynamics. Understanding how climate-driven changes—such as enhanced weathering\, glacial melt\, dust input\, and deep-sea geochemical processes—reshape the marine Si cycle is critical for predicting shifts in elemental cycling\, phytoplankton community structure\, and carbon storage. This interdisciplinary session explores evolving Si fluxes across ocean’s interfaces and their biogeochemical impacts\, encouraging studies using isotopic tracers\, omics\, satellite products\, and coupled Earth system models\, to identify hidden fluxes\, feedbacks\, and vulnerabilities in the Si cycle under changing oceanic state. \n\n\n\n*BioGeoSCAPES: Querying the Ocean’s Microbial Life Support SystemTown Hall event: Wednesday\, 25 February 2026 \n\n\n\nDescription:Earth’s life support system is underpinned by the activity of marine microbes that mediate biogeochemical cycles. BioGeoSCAPES is a community-led international effort that aims to address fundamental gaps in the mechanistic understanding of how the ocean ensemble of microbes and their  biochemical reactions shape nutrient biogeochemical cycles and are in turn influenced by these cycles. BioGeoSCAPES involves multiple scales of study\, combining integrated biological and chemical sampling with analytical techniques\, computational biology and ocean modelling. The resulting scientific efforts will deliver a coordinated and improved understanding of the structure and function of our planet’s oceans. \n\n\n\nThe town hall will report on: 1) Progress in developing the BioGeoSCAPES Science Plan\, including the science themes and international implementation strategy. 2) Upcoming webinars\, workshops and BioGeosSCAPES-related research activities and 3) Education and training activities\, including the launch of two cohorts of a BioGeoSCAPES ECR Fellows program; upcoming\, webinars\, workshops and plans for a summer school. The town hall will disseminate information\, build community engagement\, and gather feedback on BioGeoSCAPES progress and plans. The target audience includes marine microbiologists\, biogeochemists\, physiologists\, trace metal chemists\, organic geochemists\, and global\, regional and process-based modellers\, including those using machine learning and bioinformatics. \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n***SCOR Social Event***\n\n\n\n\n\n\n\n\nOpen to all!  \n\n\n\nRepresentatives from SCOR committees and activities as well as anyone–especially early-career scientists–interested in learning more about SCOR’s activities and opportunities are encouraged to attend to build connections across the community. \n\n\n\n\nDate & Time: Thursday\, 26 February\, 18:00-20:00 GMT\n\n\n\nLocation: Hotel Indigo Turbine 75 Bar\, 75 Waterloo St\n\n\n\nRSVPs are requested to best inform event arrangements. Register here.

SUMMARY:AGU2025 - General Meeting
DESCRIPTION:New Orleans\, Louisiana\, USA\, https://www.agu.org/annual-meeting \n\n\n\nCheck out the GEOTRACES sessions and join the GEOTRACES Science Exchange Event at AGU 2025!  \n\n\n\n\n\n\n\nGEOTRACES and GEOTRACES-related Sessions\n\n\n\n\n**Session OS23A – Physical and Biogeochemical Processes on the Warm Antarctic Continental ShelvesTuesday\, 16 December 2025\, 14:15 – 15:45 (local time)\, 215-216 (NOLA CC)\, Poster session: Tuesday\, 16 December 2025 \n\n\n\nThe “warm” continental shelves of West Antarctica\, which include the Amundsen and Bellingshausen seas and the West Antarctic Peninsula\, are characterized by enhanced on-shelf transport of Circumpolar Deep Water that helps determine on-shelf hydrographic and biogeochemical properties. This warm water also interacts with ice shelves\, influencing vertical mixing\, overturning rates and ice shelf mass loss\, and potentially triggering marine ice sheet instabilities. Warm shelf regions are undergoing rapid\, climate-sensitive changes\, which have important implications for ocean circulation\, biological production and biogeochemical exchange over spatial scales that may extend downstream to the Ross Sea and offshore waters of the Antarctic Circumpolar Current. For this interdisciplinary session\, we invite contributions that focus on both observational and modeling studies of ocean circulation\, sea ice-ocean and ice shelf-ocean interactions\, biogeochemical processes and biological production in Antarctic warm-shelf settings. We are especially interested in studies that explore links among these thematic topics. \n\n\n\nConveners: \n\n\n\nMadeline Mamer (Georgia Institute of Technology\, Student Convener)Kiya Riverman (University of Portland)Peter Sedwick (Old Dominion University)Robert Sherrell (Rutgers University)Andrew Thompson (Caltech) \n\n\n\nFull session details are here: https://agu.confex.com/agu/agu25/meetingapp.cgi/Session/272389 \n\n\n\n\n\n\n\n**Session A33A – Advances in Understanding Natural Aerosols and Gases in the Earth SystemWednesday\, 17 December 2025\, 14:15 – 15:45 (local time)\, 271 (NOLA CC) \n\n\n\nNatural aerosols and gases play a key role in the Earth System. They link terrestrial\, atmospheric\, and ocean processes and understanding changes in their emission and deposition is essential for assessing the climate response to human activities. This session aims to evaluate the current state of knowledge on aerosols and gases from natural sources\, such as wildfires\, dust\, volcanoes\, sea spray\, and biogenic emissions\, and to identify their impacts on climate\, biogeochemistry\, and society across diverse spatial and temporal scales. Topics of interest include\, but are not limited to: environmental drivers of natural aerosol and gas emissions; source apportionment; evolution of natural aerosol contribution to atmospheric composition; direct and indirect radiative effects; processes governing aerosol deposition and gas transfer at the air-sea and land-air interfaces; past and future changes to aerosol and gas fluxes; nutrient and contaminant exchange and impacts on ecosystems; and innovative observational approaches and modeling frameworks. \n\n\n\nConvenors:Yan FengDouglas HamiltonKostas TsigaridisNicholas Meskhidze \n\n\n\nFull session details are here: https://agu.confex.com/agu/agu25/meetingapp.cgi/Session/270649 \n\n\n\n\n\n\n\n\nGEOTRACES Science Exchange Event\n\n\n\n\nSE13B – Multi-tracer Data for Understanding and Quantifying Marine Biogeochemical Processes: the GEOTRACES Intermediate Data Product – 2025📅 Date: Monday\, 15 December 2025🕒 Time: 14:15 – 15:45 CST📍 Location: New Orleans Convention Center\, Room 343https://agu.confex.com/agu/agu25/meetingapp.cgi/Session/275608 \n\n\n\nDescriptionThis panel discussion will include presentations on the collection and collation of oceanographic tracer data\, validation of the data\, the technology for creating the Intermediate Data Product\, serving IDP2025 to the broadest scientific community\, and science highlights revealed in the data. \n\n\n\n\n\n\n\n\nProgramme \n\n\n\n\n\nThe GEOTRACES Intermediate Data Product (IDP2025): How to access and utilize the resourceWilliam Landing; Florida State University \n\n\n\nUsing GEOTRACES Intermediate Data Products in education and outreachPhoebe Lam; University of California Santa Cruz \n\n\n\nIron cycling in the mesopelagic oceanRandie Bundy; University of Washington \n\n\n\nDissolved iron input and cycling in the Amundsen SeaRob Sherrell; Rutgers University \n\n\n\nThe influence of hydrothermal inputs on the Central Pacific: Insights from the U.S. GEOTRACES GP15 and GP17-OCE expeditionsJessica Fitzsimmons; Texas A&M University College Station \n\n\n\nUse of thorium isotopes to quantify trace element input and cycling in the oceansChris Hayes; Massachusetts Institute of Technology \n\n\n\nFollowing the Particles: Using thorium-234 to trace elements pathways along U.S. GEOTRACES transectsWokil Bam; Louisiana State University \n\n\n\nMajor particle composition from the GEOTRACES GN01\, GP15\, and GP17-OCE expeditionsThao Vy Le; University of California Santa Cruz

SUMMARY:10th International Symposium in Metallomics (ISM-10)
DESCRIPTION:Ecole normale supérieure (ENS-PSL)\, Paris\, France\n\n\n\n\n\n\n\nAbstract Deadline: June 15\, 2025 (Noon\, Paris time\, CET)Early Bird Registration period: May 5th – June 31st\, 2025\n\n\n\n\n\n\n\nBackground \n\n\n\nMetal ions (such as iron\, zinc\, copper\, manganese\, nickel\, cobalt…) are essential to biology\, playing a key part in fundamental life processes such as respiration\, photosynthesis\, cell growth\, genome regulation or maintenance\, enzymatic reactions\, cell proliferation\, immune function\, oxidative stress in pathological conditions\, etc. The rich physico-chemical properties of these metal ions bring a chemical diversity in terms of structure or reactivity\, which is widely exploited by living systems. Indeed\, over 40% of living proteins are believed to contain a metal essential to their activity. \n\n\n\nMetallomics deals with the study of metals and metalloids in biology; but it extends to the study of metal-based artificial systems\, possibly bio-inspired by some components of the metallome\, and their uses in health\, energy and the environment. Other disciplines resort to techniques to analyze metallic speciation\, structure and physico-chemical related properties: the cross-talk with geology or arts can be fertilizing and we will take the opportunity of this congress to open up the frontiers of biology to other disciplines dealing with the characterization of metal ions\, including arts and heritage. \n\n\n\nThe 10th edition of International Symposium of Metallomics will take place at the Ecole normale supérieure (ENS-PSL\, Paris\, France). You will have the opportunity to discover the historical location where Louis Pasteur and Jules Raulin\, one of his collaborators who discovered in 1869 that zinc salts were required for the growing of Aspergillus niger\, worked. \n\n\n\nRelevant Themes: “Metals and geochemistry environment” and “Metals and remediation\, recycling”.Plenary Speaker: Prof. Woodward Fischer\, Caltech\, division of Geological and Planetary Sciences\, “Evolution of metal availability and utilization by the early biosphere through Earth’s Great Oxygenation” \n\n\n\nFor further information: https://www.notis-event.com/ISM-2025

SUMMARY:2025 Gordon Research Conference (GRC) and Seminar (GRS) on Chemical Oceanography
DESCRIPTION:Location: Southern New Hampshire University\, Manchester\, New Hampshire\, United States\n\n\n\nGordon Research Conference (GRC) on Chemical Oceanography: Fingerprints in the Ocean\n\n\n\nThe Chemical Oceanography GRC is a premier\, international scientific conference focused on advancing the frontiers of science through the presentation of cutting-edge and unpublished research\, prioritizing time for discussion after each talk and fostering informal interactions among scientists of all career stages. The conference program includes a diverse range of speakers and discussion leaders from institutions and organizations worldwide\, concentrating on the latest developments in the field. The conference is five days long and held in a remote location to increase the sense of camaraderie and create scientific communities\, with lasting collaborations and friendships. In addition to premier talks\, the conference has designated time for poster sessions from individuals of all career stages\, and afternoon free time and communal meals allow for informal networking opportunities with leaders in the field. \n\n\n\nPhysical\, chemical\, biological\, and geological processes in the ocean leave chemical fingerprints. The discipline of chemical oceanography uses these fingerprints to understand important ocean processes. It both borrows from other fields to help in the interpretation of chemical data\, as well as offers insights into other fields allowing the inference of processes and mechanisms that may not be otherwise measurable. This Chemical Oceanography GRC will continue the tradition of presenting research at the cutting edge of this integrative field\, spanning orders of magnitude in time and spatial scales. The conference will bring together experimentalists\, observationalists\, and modellers who study the generation and interpretation of chemical fingerprints in the ocean and at its interfaces. \n\n\n\nApplications for this meeting must be submitted by June 22\, 2025. \n\n\n\nCheck the programme: https://www.grc.org/chemical-oceanography-conference/2025/ \n\n\n\nThis GRC will be held in conjunction with the “Chemical Oceanography” Gordon Research Seminar (GRS)\, see below. Those interested in attending both meetings must submit an application for the GRS in addition to an application for the GRC. \n\n\n\nGordon Research Seminar (GRS): Chemical Tracers in a Changing Ocean\n\n\n\nThe Chemical Oceanography GRS provides a unique forum for young doctoral and post-doctoral researchers to present their work\, discuss new methods\, cutting edge ideas\, and pre-published data\, as well as to build collaborative relationships with their peers. Experienced mentors and trainee moderators will facilitate active participation in scientific discussion to allow all attendees to be engaged participants rather than spectators. \n\n\n\nApplication InstructionsThe seminar will feature approximately 10 talks and 2 poster sessions. All attendees are expected to actively participate in the GRS\, either by giving an oral presentation or presenting a poster. Therefore\, all applications must include an abstract. \n\n\n\nThe seminar chair will select speakers from abstracts submitted by April 13\, 2025. Those applicants who are not chosen for talks and those who apply after the deadline to be considered for an oral presentation will be expected to present a poster. In order to participate\, you must submit an application by the date indicated in the Application Information section above. \n\n\n\nProgram FormatGordon Research Seminars are 2-day meetings which take place on the Saturday and Sunday just prior to the start of the associated GRC. The GRS opens with a 1-hour introductory session on Saturday afternoon\, followed by a poster session\, dinner and a 2-hour session in the evening. Sunday morning begins with breakfast and is followed by another 2-hour session\, a second poster session\, and lunch. A final 1-hour session takes place just after lunch\, and the associated GRC begins later that evening. \n\n\n\nApplicationsApplications for this meeting must be submitted by June 21\, 2025. Please apply early\, as some meetings become oversubscribed (full) before this deadline. If the meeting is oversubscribed\, it will be stated here. Note: Applications for oversubscribed meetings will only be considered by the conference chair if more seats become available due to cancellations. \n\n\n\nGRS Speaker Abstract Deadline: Although applications will be accepted until the date noted above\, any applicants who wish to be considered for an oral presentation should submit their application by April 13\, 2025. Please refer to the application instructions in the Conference Description section below for more details (if available). \n\n\n\nFor further information: https://www.grc.org/chemical-oceanography-grs-conference/2025/

SUMMARY:Goldschmidt 2025
DESCRIPTION:Prague\, Czech Republic \n\n\n\nGoldschmidt is the foremost annual\, international conference on geochemistry and related subjects\, organized by the Geochemical Society and the European Association of Geochemistry. \n\n\n\nWe draw your attention to the following GEOTRACES sessions: \n\n\n\n\n\n\n\nList of GEOTRACES and GEOTRACES-related sessions:\n\n\n\n\n*12a – Elemental Enigmas: Cracking the Code of Trace Metals in Polar Oceans \n\n\n\nThe cycling of trace metals in polar oceans is crucial for understanding biogeochemical processes and ecosystem health in these sensitive environments. Trace metals such as Fe\, Zn\, Ni\, Mn\, and Co are essential micronutrients that regulate phytoplankton productivity across vast regions of the global ocean\, notably the Southern Ocean and Arctic\, significantly impacting carbon cycling between ocean and atmosphere. In contrast\, toxic elements such as Hg which is of special concern in Arctic\, are posing potential environmental risks. Polar regions act as critical zones for ocean-atmosphere interactions\, with trace metal inputs from sea ice\, icebergs\, weathering\, melting permafrost\, hydrothermal activity\, continental shelf sediments\, and atmospheric deposition altering primary production. Trace metal isotopes and other means such as rare earth element composition have revolutionized our ability to trace the sources\, pathways\, and biogeochemical processes of trace metals in the ocean. These tools allow us to distinguish external input and disentangle biogeochemical processes such as biological uptake\, particle‐solution exchange\, and remineralization\, and provide insights into past ocean conditions.However\, the remoteness\, extreme weather\, and technical challenges in clean sampling and trace metal analysis hinder our understanding of their cycling in the rapidly changing polar oceans. Enhancing our knowledge of these understudied regions is critical\, as polar seas and the cryosphere act as precursors for global changes in other ecosystems. To this end\, this session invites research integrating isotopic\, trace metal data\, and biogeochemical models to explore sources\, cycling\, and biological responses\, advancing predictions of polar ocean impacts on climate change. \n\n\n\nConveners: \n\n\n\nHung-An TianAlfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung \n\n\n\nSaša MarcinekRuder Boskovic Institute \n\n\n\nRhiannon JonesBritish Antarctic Survey \n\n\n\n\n\n*12e – Tracing marine trace element dynamics: impact of external sources and oceanic cycling \n\n\n\nTrace elements and isotopes (TEIs) in the ocean play pivotal roles in primary productivity\, carbon cycling\, and marine biodiversity\, and serve as powerful tracers of oceanic processes. To reliably apply these geochemical proxies\, it is essential to develop a thorough understanding of the oceanic distribution of TEIs and physical and chemical processes that influence these patterns. The processes that influence the oceanic TEI distribution include inputs from various sources (e.g.\, river-estuarine\, atmospheric deposition\, submarine groundwater discharge\, hydrothermal inputs and marine benthic dynamics) and oceanic internal cycling (biological uptake and remineralization\, reversible scavenging\, particle-water interaction\, redox conditions\, and ocean circulation). Since the start of the GEOTRACES program\, observational TEI datasets have been rapidly accumulating\, providing valuable resources to the state-of-the-art ocean modeling tools to test hypotheses and predict distributions in regions that are still poorly constrained. This knowledge not only offers significant insights into the debate about the controls of modern ocean chemistry but also aids in resolving discrepancies arising from conflicting paleo-records of multiple geochemical proxies.This session invites contributions from observational\, experimental\, and modeling studies specifically focusing on (i) understanding the TEI distribution\, species\, and bio-availability in the ocean in connection to various sources and internal cycling\, (ii) the impact of processes at oceanic boundaries (atmosphere\, land\, shelf\, hydrothermal vents) on oceanic TEI distributions\, (iii) new insights into the processes of open ocean cycling\, (iv) application of AI/ML and other modeling techniques in assessing the marine TEI distribution. We encourage submissions based on multi-disciplinary and multi-proxy approaches. \n\n\n\nConveners: \n\n\n\nKai DengTongji University \n\n\n\nVineet GoswamiPhysical Research Laboratory \n\n\n\nAntao XuHeidelberg University \n\n\n\nSunil SinghCSIR-National Institute of Oceanography \n\n\n\n\n\n*12g – Seafloor hydrothermal processes and their impacts on the modern and ancient Earth \n\n\n\nSeafloor hydrothermal systems have profoundly influenced Earth’s biosphere\, lithosphere\, hydrosphere\, and atmosphere throughout Earth history and serve as crucial pathways for the transfer of materials and energy between the lithosphere and the exosphere (biosphere\, hydrosphere\, and atmosphere) today. Nonetheless\, hydrothermal systems’ nature within the oceanic crust drastically limits the temporal extent of direct geologic observations of their existence. Thus\, attempts to correlate seafloor hydrothermal processes with biological evolution\, global elemental budgets\, and global redox states throughout Earth history generally require interdisciplinary efforts that integrate studies of modern systems\, interpretations of the geologic record\, novel laboratory experiments\, and numerical models. Specific focuses could include the role of seafloor hydrothermalism in carbon and other elemental cycles\, studies of the linkages between high and low temperature hydrothermal alteration\, crustal mineralogy\, and seawater geochemistry\, and the relation between hydrothermal systems and the tempos and milestones of biological evolution. Submissions from early career researchers are especially welcome. \n\n\n\nConveners \n\n\n\nBenjamin M.

However\, reconstruction of deep-time climatic and environmental change from sedimentary records remains challenging. New tools are needed to investigate poorly known aspects of paleoenvironmental systems as well as to test interpretations made using established paleoenvironmental proxies.The scope of this theme session includes novel proxy development as well as new constraints on existing geochemical proxy records. Topics include\, but are not limited to\, proxy development and calibration in modern and ancient systems (e.g.\, GEOTRACES)\, experimental constraints\, data-model calibrations\, and novel proxy applications in the ancient sedimentary record. We especially encourage submissions with new and innovative insights regarding mechanisms\, feedbacks\, or quantitative thresholds driving ancient geochemical perturbations and their relationship with environmental\, climatic\, and biological evolution. \n\n\n\nConveners \n\n\n\nJun ShenChina University of Geosciences\, Wuhan \n\n\n\nThomas J.

SUMMARY:GEOTRACES Synthesis Preparation Workshop - Hybrid format
DESCRIPTION:Hanse-Wissenschaftskolleg\, Institute for Advanced Study (HWK)\, Delmenhorst (Germany) and online\n\n\n\nThe originally anticipated full-week synthesis workshop in Delmenhorst cannot take place\, but the reserved meeting place\, back to back with the subsequent Goldschmidt conference in Prague\, offers a unique and timely opportunity to prepare synthesis activities and to explore funding opportunities and partner networks. \n\n\n\n\n\n\n\nMuch has been learned and accomplished since the launch of GEOTRACES in 2010\, but more can be revealed by combining results and exploring different approaches to synthesize data. Since the GEOTRACES Science Plan was originally developed\, new tools for synthesis\, outreach\, collaboration and societal impact have become available- in addition to the anticipated tools like workshops\, modelling and publication in manuscripts and databases. The GEOTRACES Scientific Steering Committee (SSC) has sharpened its ideas regarding synthesis and formulated recommendations\, which wait to be implemented. At the same time\, funding of future activities for GEOTRACES is essential now to keep the momentum and realize the potential impact of the new wealth of knowledge on trace elements and their isotopes. \n\n\n\n\n\n\n\nGiven this background\, the aims of our two-day workshop are two-fold: \n\n\n\n\nWe would like to take this opportunity to explore and compile the various aspects of synthesis including novel approaches\, based on existing SSC recommendations and beyond. Based on these aspects\, we will form one or several groups of authors/contributors. The aim for this group is to provide a synthesis preparation document draft that can be circulated to the SSC\, and that can be approved or modified during the annual SSC meeting in Goa later this year. Eventually\, this document is supposed to be published and might form a key resource for planning coming synthesis activities.\n\n\n\n\n\n\n\n\n\nThe conceptualization of coming synthesis activities -including outreach\, societal impact and filling in research gaps in future research- is tightly linked to possible proposals for funding. During our workshop\, participants can present promising funding opportunities for GEOTRACES research\, identify possible partners and start building consortia- to be continued during the following week in Prague.\n\n\n\n\n \n\n\n\n\n\n\n\nProgramme\n\n\n\nThe programme is available to download here. \n\n\n\n\n\n\n\nPre-registration\n\n\n\nPre-registration closed on 15 May 2025. \n\n\n\nThe total number of participants is limited to 55 as follows: 25 in person and 30 online.

SUMMARY:EGU General Assembly 2025
DESCRIPTION:Vienna\, Austria & Online\n\n\n\nThe EGU General Assembly 2025 brings together geoscientists from all over the world to one meeting covering all disciplines of the Earth\, planetary\, and space sciences. The EGU aims to provide a forum where scientists\, especially early career researchers\, can present their work and discuss their ideas with experts in all fields of geoscience. \n\n\n\n \n\n\n\nGEOTRACES relevant session:\n\n\n\nChemical Processes in Coastal Oceans: Natural and Anthropogenic impacts on the biogeochemical processes \n\n\n\nConvener: Aridane González González | Co-conveners: David González-Santana\, J. Magdalena Santana-Casiano\, Melchor Gonzalez-Davila \n\n\n\nCoastal oceans are dynamic interfaces between land and sea\, playing a critical role in global biogeochemical cycles with a high impact on socio-economic activities and social developments. The dynamic and physical processes as well as the human activities that take place in coastal areas make them natural laboratories to improve our knowledge about several biogeochemical interactions. In addition\, these regions are affected by both natural and anthropogenic factors such as coastal acidification\, organic matter\, nutrients\, and pollution\, among others. All these factors have impacts on the natural cycles and the magnitude of these impacts should be studied and understood in order to propose solutions to the decision makers that could help to know\, understand\, take decisions\, and protect or regulate the coastal environments. \n\n\n\nThis session aims to bring together researchers from diverse fields to discuss the latest findings on the biogeochemical processes occurring in coastal oceans\, improve our knowledge\, identify impacts\, and propose solutions. We welcome research studies that focus on both natural and anthropogenic processes that are affecting the trace metal chemistry\, CO2 system\, ocean acidification\, nutrient cycle\, organic matter\, CO2 sequestration and their impacts on the chemical processes\, etc. \n\n\n\nShare:https://meetingorganizer.copernicus.org/EGU25/session/52604

SUMMARY:AGU2024 Annual Meeting
DESCRIPTION:Washington\, DC. USA and online.https://www.agu.org/annual-meeting \n\n\n\n\n\n\n\nWhat’s Next for Science \n\n\n\nEach year\, AGU’s annual meeting\, the largest gathering of Earth and space scientists\, convenes 25\,000+ attendees from 100+ countries to share research and connect with friends and colleagues. Scientists\, educators\, policymakers\, journalists and communicators attend AGU24 to better understand our planet and environment\, opening pathways to discovery\, opening greater awareness to address climate change\, opening greater collaborations to lead to solutions and opening the fields and professions of science to a whole new age of justice equity\, diversity\, inclusion and belonging. \n\n\n\n\n\n\n\nFind below the information on two GEOTRACES sessions and a related event at AGU2024: \n\n\n\n\n\n\n\nGEOTRACES sessions:\n\n\n\n*OS23H – Trace Element Distributions and Cycling Across Ocean Basinshttps://agu.confex.com/agu/agu24/meetingapp.cgi/Session/236929Tuesday\, 10 December 2024Marine trace elements and their isotopes regulate primary production and provide tracers of past and present oceanic processes\, including circulation and particle export. The influence of trace elements on productivity and the ocean carbon cycle is particularly notable in the remote Southern Ocean\, where distant or ice-covered continents provide reduced inputs and water mass circulation impacts global transfer of heat and nutrients. A number of recent expeditions have sampled these waters\, providing new data on tracing external elemental fluxes to the region\, constraining complex biogeochemical processes\, and measuring their imprint on subsurface water masses. This session invites presentations addressing the sources\, sinks\, and cycling of trace elements in the ocean\, particularly as studied using ocean basin sections. Results from fieldwork and/or modeling studies in the Southern Ocean\, Antarctic Circumpolar Current\, and Antarctic coastal waters are particularly encouraged\, though results from all ocean basins are welcome.Primary ConvenerBenjamin S Twining\, Bigelow Lab for Ocean SciencesConvenersJessica N Fitzsimmons\, Texas A&M University College StationGregory A Cutter\, Old Dominion University \n\n\n\n\n*OS41H – Disentangling Hydrothermal Impacts on Ocean Biogeochemistryhttps://agu.confex.com/agu/agu24/meetingapp.cgi/Session/237098Thursday\, 12 December 2024 \n\n\n\n\nExciting new research reveals the significant impact of submarine hydrothermal venting on ocean biogeochemistry at both basin and global scales. Understanding this impact requires examining processes across various scales and integrating multiple disciplines\, including observations\, experiments\, data synthesis\, and modeling. This session invites submissions on hydrothermal biogeochemistry research across all venting styles and scales. It aims to connect drivers of hydrothermal processes from marine geoscience\, organic geochemistry\, ocean circulation\, carbon and biogeochemical cycles\, and marine microbiology. We especially welcome contributions from international programs like GEOTRACES and InterRidge\, and novel research on diverse seafloor fluid flow systems worldwide\, such as mid-ocean ridges\, intraplate seamounts\, convergent margins\, and transform faults. Field\, laboratory\, and theoretical studies on the roles of hydrothermal systems in the cycling and transformation of organic matter and nutrients in the oceans are also encouraged.Primary ConvenerChristopher R German\, WHOIConvenersChristopher R German\, WHOIRandelle M Bundy\, University of Washington Seattle CampusAlessandro Tagliabue\, University of LiverpoolStudent/Early Career ConvenerAlexandria Aspin\, Oakland University \n\n\n\n\n\nRelated event that the organisers asked the IPO to share:\n\n\n\nCommunity Meeting – UNOLS Arctic Marine Research Capabilities Committee (AMRCC)December 10\, 202412:30-13:30Westin DC Downtown\, 9th St NW\, Washington\, DCThe AMRCC is a UNOLS Special Committee established in June 2024 by the UNOLS Chair and Council at the request of the NSF\, ONR\, and USARC. The purpose of the Committee is to reviewand refresh science missions and affiliated science mission requirements (SMRs) of future Federal icebreakers operating in the Arctic Ocean and other northern polar regions. To do so\, the Committee is assessing if the existing science missions and SMRs for such missions meet current and emerging needs for Arctic research on Federal icebreakers and is identifying any additional SMRs required to ensure that Federal icebreakers will meet the needs of the Arctic marine research community for the next 30 years. Specifically\, the Committee is reviewing and refreshing SMRs for (a) any commercially available polar icebreaker that may be acquired or procured and refit for operation by the Federal government; and (b) the conceptual design of future “medium” or “heavy” Federal-flagged and owned icebreakers.At this meeting\, Committee members will review the charge to the Committee and the Committee’s activities to date and will welcome comments and input on envisioned science directions and research cruises in the Arctic Ocean for the next 30 years\, on existing and future gaps in our ability to address these questions\, and on critically needed science enabling capabilities of federal vessels in the Arctic Ocean.Please contact Carin Ashjian (cashjian@whoi.edu)\, AMRCC Chair\, or Doug Russell (doug@unols.org)\, UNOLS Executive Secretary\, with any questions. The Westin DC Downtown is an ~5-minute walk from the Convention Center.See: https://www.unols.org/committee/special-committee-arctic-marine-research-capabilities-committee-amrcc for more information on the Committee.

Nowhere are these controls more evident than at transitions between the ultra-oligotrophic subtropical gyres\, the highly productive waters of the Antarctic Circumpolar Current\, and the HNLC waters surrounding Antarctica. Sampling across these regimes allows the processes affecting the cycling of trace elements and isotopes to be revealed. Indeed\, programs such as SOCCOM\, GEOTRACES\, SOLAS\, and GO-SHIP have used sampling and transects in these transitional waters of the Southern Ocean. This session invites presentations on processes affecting trace elements and isotopes\, methods to study them\, and modeling approaches to explore mechanisms and rates of biogeochemical processes that are revealed in waters near the Southern Ocean. \n\n\n\nGeochemical tracers of ocean processes \n\n\n\nInternational programs such as GEOTRACES have greatly improved our understanding of the basin-scale distributions of carbon\, nutrients\, and trace elements and isotopes (TEIs) in the ocean. However\, data gaps still exist around the sources\, sinks\, and internal cycling processes that set the observed distributions. Naturally occurring radioactive isotopes can be applied as geochemical tracers to help constrain the rates of TEI input\, removal\, and transport\, while stable isotopes are exploited as tracers of sources and of internal cycling. Such processes may include the supply of aerosols to the ocean\, export of material from the surface ocean\, particle dynamics and fluxes of sinking particulate material\, sources to the water column from the early diagenesis of sediments\, sources from submarine groundwater discharge\, biological uptake of nutrients and nutrient-like chemical species\, and more. This session will be of interest to investigators applying geochemical tracers in the study of any of these processes\, using observational and/or modeling approaches. It is hoped that synthesis activities combining different TEIs or combining models with observations will emerge as a product of this session. \n\n\n\nBiogeochemical Cycling in the Caribbean Sea\, the Gulf of Mexico and Beyond \n\n\n\nThe Caribbean and Gulf of Mexico are dynamic\, interconnected\, marginal seas that host the complete range of marginal ocean environments\, including coastal shelves\, eutrophic coastal systems\, oligotrophic open waters\, anoxic basins\, dust gradients\, hydrocarbon seeps\, and hydrothermal/volcanic activity. A panoply of margin fluxes (atmospheric\, riverine\, submarine groundwater\, etc)\, the Mississippi\, productivity gradients\, periodic algal blooms\, and pollution events all drive regional spatial and temporal variability in the biogeochemistry of nutrients and trace elements and isotopes (TEIs)\, making the region an ideal natural laboratory for testing biogeochemical hypotheses. Teleconnections between the Caribbean\, the Gulf\, the Gulf Stream\, and the Atlantic provide unique opportunities for investigating how marginal environments transform and modify supply of nutrients and TEIs to open ocean waters. We invite contributions that characterize variability in the biogeochemistry/geochemistry of the Gulf and the Caribbean\, and especially the linkages between these seas and the Atlantic. Suggested submissions may include: water column nutrient\, TEI\, or geochemical distributions and fluxes; biogeochemical rate measurements\, regional biogeochemistry\, and descriptions of circulation that impact biogeochemical dynamics. This session aims to bring together interested international investigators to highlight findings and to identify areas of common interest and collaborative opportunities to help inform future planning in national/international programs. \n\n\n\nSpeciation and Bioavailability of Trace Metals in the Marine Environment \n\n\n\nThe trace metals manganese\, iron\, cobalt\, nickel\, copper\, zinc\, and cadmium play important roles in the productivity and composition of marine phytoplankton communities. Some of these metals serve as limiting nutrients to phytoplankton in open ocean regions\, others can substitute for essential metals that are less abundant\, and still others can be toxic at elevated concentrations. The bioavailability of trace metals to phytoplankton and microorganisms is largely governed by their chemical form\, or speciation\, in seawater. Insights from recent studies have highlighted the range of strategies that microorganisms employ to acquire the metals they need and the interplay between trace metals during phytoplankton growth and decay. However\, there is still much left to learn about biogeochemical controls on trace metal bioavailability and how changing ocean conditions may influence trace metal cycling and speciation. This session welcomes submissions from across the field of trace metal biogeochemistry\, including temporal and spatial studies of metal speciation from GEOTRACES and other efforts\, and experimental or modeling studies that examine feedbacks between microorganisms and trace metal chemistry\, interactions between trace metals in natural systems\, or the impacts of changing conditions (e.g.\, pH\, oxygen\, temperature) on trace metal speciation or bioavailability. \n\n\n\nObservation-Based Data Products of Ocean Biogeochemistry and the Importance of Standardized Measurement and Uncertainty Estimation Protocols in Marine Science \n\n\n\nAccurate observations of ocean environmental parameters are essential for advancing scientific knowledge and informing management decisions\, and have revealed significant ocean changes over recent decades. However\, inconsistencies in instrumentation and measurement protocols can hinder data comparison and synthesis across studies. Further\, discrepancies between observations and models\, which are important tools for projecting future changes\, remain challenging to assess due to the spatiotemporal sparsity and methodological heterogeneity of ocean biogeochemical observations. The availability of open datasets from large-scale measurement campaigns (e.g.\, Argo and Biogeochemical Argo\, GEOTRACES\, GO-SHIP\, EXPORTS) presents opportunities to apply statistical\, machine-learning\, and/or interpolative techniques to fill gaps in scattered observations to produce global\, seasonally and inter-annually resolved data products. This prospect of constructing gap-filled products from heterogenous observational datasets necessitates the adoption of standardized\, consistent measurement protocols. This session will bring together researchers involved in the creation\, analysis\, or optimization of ocean observational products and the designing\, testing\, and implementing community consensus protocols for measurement standardization. Presentations will showcase new and in-development products and foster discussion about utilizing large datasets\, interpolating between observations\, promoting consistency in measurement protocols and uncertainty estimations\, and examining the role of technological advances in the measurement of ocean parameters. \n\n\n\nTime-series observations of ocean biogeochemistry: what we have learned and what we will learn. \n\n\n\nOcean time-series monitoring and sampling has provided several scientific and societal insights\, such as understanding climate-driven changes in ocean temperature\, biogeochemical cycles and marine ecosystems. Several long-term multi-variable data sets covering the atmosphere’s and ocean’s physics from the surface to the deep layer are international available in data repositories (e\,g.\, OceanSITES\, BCO-DMO). However\, data sets of water column and seafloor biogeochemistry measurements are not fully sufficient to our understanding of ocean function. For example\, there is still a lack of understanding of the relationship between surface primary production\, the biological carbon pump\, and the carbon requirements of organisms in the deeper layers. Furthermore\, long-term data to understand the coupling between biological responses and biogeochemical cycling and increasing environmental multi-stressors\, such as global warming\, acidification\, and anoxia\, is essential. In this session\, we will emphasize the importance of sustained ocean time-series programs\, and discuss the key issues that should be addressed to maintain and enhance ocean observation systems and reduce uncertainties in model predictions\, in addition to the knowledge obtained from time-series observations to date\, as well as the linkage of various approaches\, such as field observations\, satellite observations\, numerical models\, and technological development. \n\n\n\nThe influence of boundary currents on exchange processes between continental margins and the open ocean and biogeochemical consequences \n\n\n\nContinental shelf margins and their adjacent boundary current systems are significant in global budgets of heat\, freshwater and biogeochemical properties\, and are regions of strong air-sea interactions and frontal instabilities. The transport and exchanges of water masses\, heat\, nutrients\, biogeochemical constituents\, and pollutants between ocean margins and the open ocean influence biodiversity\, biomass\, and biological interactions in marine food webs\, which consequently mediate the fate of carbon and element flows. However\, understanding these exchanges has been hindered by the “scale gap” between local mixing processes\, cross shelf and onshore transport\, and interactions with boundary currents. This session explores new approaches to close the scale gap in understanding coast – ocean exchange. We encourage submissions based on empirical observations\, numerical and theoretical models that focus on: (1) material exchange in western and eastern boundary current systems; (2) the role of mesoscale and submesoscale circulations in transporting material across isobath barriers; and (3) modeling approaches that bridge the scale gap. We particularly welcome studies that focus on seasonal cycles and inter-annual variability\, climate change impacts\, extreme events\, multiscale processes\, trends\, and linkages to ecosystems. \n\n\n\n\n\n ** GEOTRACES-related events **\n\n\n\n\n\n\n\nMarChemSpec at the Ocean Sciences Meeting \n\n\n\nThose will long GEOTRACES memories will be aware of the chemical speciation modelling initiative that began as SCOR Working Group 145. This initiative has now transitioned to be a part of the IAPSO/SCOR/IAPWS Joint Committee on the Properties of Seawater. \n\n\n\nAt Ocean Sciences 2024 the group will release version 1.1 of the software product. The software is freely available via the website marchemspec.org\, and can be run standalone or called from MATLAB or Python. New for version 1.1 is the ability to fix any two of the CO2 system parameters. \n\n\n\nProject leaders David Turner and Simon Clegg will present posters on MarChemSpec applications to marine carbon dioxide removal (mCDR) (CM24A-1140) and trace metal complexation (OB34C-0880) at OSM24. Meet them at their posters and visit the Ocean Carbon & Biogeochemistry (OCB) Exhibit Booth (BOOTH 512\, OSM Exhibit Hall) to test drive the new software. David and Simon will be at the meeting all week\, and their availability at the OCB booth is likely to be broadly: \n\n\n\n\nTuesday: 10 am – 6 pm\n\n\n\nWednesday: 10 am – 4 pm\n\n\n\nThursday: 10 am\, 12 noon – 1 pm\n\n\n\n\nIf you want to arrange a specific time to meet\, please email to david.turner@marine.gu.se  or s.clegg@uea.ac.uk \n\n\n\n\n\n\n\nTown Hall “Margin/Basin Biogeochemical Dynamics: Priorities and Future Directions“ \n\n\n\nhttps://agu.confex.com/agu/OSM24/meetingapp.cgi/Session/195029 \n\n\n\nMonday\, 19 February 2024 – 12:45 – 13:45 (local time) \n\n\n\nContinental margins play a critical role in the exchange of materials between the continents and ocean basins\, and are important as sources and sinks of oxygen in their own right.   They have great economic and societal importance in terms of natural capital\, including fisheries.    Margin systems are influenced by processes common to all margins as well as factors reflecting the physical characteristics of each system.   Overlaying this complexity are the long-term effects of climate change\, which is predicted to impact marginal seas sooner than interior basins.   Recent innovations in modeling and observational technologies have the potential to advance our understanding of the biogeochemistry of this vital component of the marine system.   This Town Hall will address the future objectives of biogeochemical research in internal cycling within margins and exchange processes with ocean basins.   The Ocean Sciences Meeting is a good forum because of the strong international component. Several nations\, including Japan and Germany\, have developed very strong interdisciplinary region-specific programs spanning multiple years and we have much to learn from them.  We will also address challenges including establishing a consensus on benthic flux measurements as well as strategies link margin processes with processes occurring at the land-margin interface.
