SUMMARY:US GEOTRACES GP17 cruise planning workshop
DESCRIPTION:Note: To to the COVID-19 situation\, this meeting will be held online via Zoom 6-8 May 2020. 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.

SUMMARY:Virtual Goldschmidt 2020
DESCRIPTION:Goldschmidt 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\nGEOTRACES session: \n\n\n\n14m: Biogeochemical Cycling of Trace Elements and their Isotopes in the Oceans (GEOTRACES) \n\n\n\nConveners: Tim Conway\, Mariko Hatta\, Nick Hawco \n\n\n\nKeynote: Brandy TonerInvited Speakers: Jun Nishioka\, Sam Wilson \n\n\n\nTrace elements and their isotopes (TEIs) play critical roles in ocean biogeochemistry and carbon cycling\, as well as providing new insights into oceanic processes such as circulation\, ventilation\, particle scavenging\, primary productivity\, redox state and source/sink processes. 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.

SUMMARY:AGU Fall Meeting
DESCRIPTION:GEOTRACES-related session: \n\n\n\nTitle: Advances in Understanding Meridional Overturning Circulation from Past to Future: Insights from Multiple Approacheshttps://agu.confex.com/agu/fm20/meetingapp.cgi/Session/110375 \n\n\n\nAbstract:The Meridional Overturning Circulation (MOC) is a major driver of Earth’s climate and biogeochemical cycling on many timescales. 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

SUMMARY:Fukushima Dai-ichi and the Ocean: 10 years of study and insight
DESCRIPTION:The events in Japan that began on March 11\, 2011\, with the country’s largest recorded earthquake and a tsunami of remarkable power\, leading to the initial and ongoing releases of radioactive materials from the Fukushima Dai-ichi Nuclear Power Plant. \n\n\n\nJoin us on March 4th as we look back at what we’ve learned over the past 10 years during two virtual panels\, both at 7:30 pm\, one timed for Tokyo with the second for the U.S. East Coast\, using simultaneous translation at the Tokyo event for Japanese and English speakers. \n\n\n\nYou will need to register for these free panel events: https://cmer.whoi.edu/10-years-of-study-and-insight/ \n\n\n\nWe are pleased to announce that the panels will be moderated by Miles O’Brian\, with keynote introductions by Atsuko Yoko Fish (Tokyo event) and Caroline Kennedy (US event). The panel of four experts- J. Kanda (Tokyo U. Marine Sci & Tech)\, K. Buesseler (WHOI\, USA)\, S. Charmasson (IRSN\, France)\, A. Brown (Safecast\, Japan)- will review events that occurred\, explore the fate of the radioactive contaminants in the ocean\, the consequences for marine life and human consumers of seafood\, and finally explore communication of these events to the public. The presentations and panel discussion will be moderated with the general public in mind and will be of interest to policy-makers\, industry leaders\, and the research community. It will also include time for questions from the audience. \n\n\n\nFinally\, during the week of March 4-11\, we will host a virtual poster session accompanied by short audio presentations in English and Japanese with the option to leave your questions for the poster authors. \n\n\n\nTogether\, the keynotes\, panels\, and poster session will offer a fitting memorial of events in 2011 and will also provide an informative and accessible summation of work that occurred over the past decade as a result.

SUMMARY:ASLO 2021\, Aquatic Sciences Meeting
DESCRIPTION:Virtual Meeting\n\n\n\nAquatic Sciences for a Sustainable Future:  Nurturing Cooperation\n\n\n\nInitially this meeting was scheduled to be held in Palma\, but due to COVID-19\, it is necessary to hold the ASLO 2021 Aquatic Sciences Meeting virtually. 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/

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.

SUMMARY:2021 Gordon Research Conference (GRC) and Seminar (GRS) on Chemical Oceanography - Deferred to 2023!
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/

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).

SUMMARY:Blowing South: Southern Hemisphere Dust Symposium
DESCRIPTION:Symposium Website: http://dust2021.cima.fcen.uba.ar/Download the brochure \n\n\n\nAbstract submission will close on 21 September 2021. NEW DEADLINE! \n\n\n\nRationale:\n\n\n\nDust is an essential component of the climate and the Earth system dynamics\, participating in feedbacks with the radiative balance\, precipitation\, atmospheric and ocean biogeochemistry and land use\, including impacts on human health. Compared to the Northern Hemisphere\, dust in the Southern Hemisphere has traditionally received less attention. However\, a growing body of literature stresses the importance of dust in southern latitudes\, since southern land masses are the most important sources of dust deposited on the southern oceans\, the most extensive of the high-macronutrient\, low-chlorophyll water bodies. In southern polar and subpolar regions\, the long-range transport of dust potentially affects high-latitude albedo of snow- and ice-covered surfaces. \n\n\n\nSymposium aim:\n\n\n\nThis symposium will focus on bringing together international scientists working on observation and modeling of the present-day and paleo dust cycle in the Southern Hemisphere\, across temporal and spatial scales\, including both feedback with climate and impact on society. \n\n\n\nParticipants will discuss the latest advances in their work and share their major scientific questions. This will provide an opportunity to discuss recent and on-going work on these critical issues\, and to expand on pre-existing collaborations that in certain areas of research and in certain regions are still quite limited. \n\n\n\nContact: shdustsymposium@gmail.com

The development of these proxies is driven by linking relationships between processes in the modern ocean and the transfer of signals into preserved archives\, ranging from bulk sediment to species-specific fossils. The international GEOTRACES program has been surveying the global ocean distribution of trace elements and isotopes\, many of which have specific paleoceanographic applications\, including protactinium-thorium ratios and neodymium isotopes. Furthermore\, the advancements GEOTRACES has made in the understanding of micronutrient metals\, redox sensitive metals and nutrient isotopic ratios also have significant implications for our understanding of past ocean circulation\, biological productivity\, particle Kuxes and climate. In this session we welcome abstracts focusing on either modern or past ocean systems that speak to the development\, calibration\, or modeling of proxies and/or any associated updates to our proxy-based understanding of ocean conditions \n\n\n\nCo-conveners: Christopher Hayes\, Kazuyo Tachikawa\, Kassandra Costa and Jesse R Farmer.

SUMMARY:Ocean Sciences Meeting 2022
DESCRIPTION:Virtual event.  \n\n\n\nWeb page: https://www.aslo.org/osm2022/ \n\n\n\n\n\n\n\nGEOTRACES Town Hall:\n\n\n\nTH33 Accessing and utilizing the GEOTRACES 2021 Intermediate Data Product (IDP2021) \n\n\n\nThe international GEOTRACES program aims to identify processes and quantify fluxes that control the distributions of key trace elements and isotopes in the ocean\, and to establish the sensitivity of these distributions to changing environmental conditions. GEOTRACES has just released a new intermediate data product (GEOTRACES IDP2021)\, combining data acquired during the first 10 years of the program. It contains datasets on trace elements that serve as micronutrients\, tracers of continental sources to the ocean (e.g.\, aerosols and boundary exchange)\, contaminants (e.g.\, Pb and Hg)\, radioactive and stable isotopes used in paleoceanography and a broad suite of hydrographic parameters used to trace water masses. IDP2021 expands on\, and includes\, the collection of results from the Atlantic\, Pacific\, and Southern Oceans (IDP2014 and IDP2017) and includes new data from the Pacific\, Arctic and Indian Oceans. In addition\, IDP2021 includes a significant amount of BioGEOTRACES data on ligands\, enzymes\, and single cell quotas. IDP2021 will be of value to chemical\, biological\, and physical oceanographers\, especially those interested in biogeochemical cycles and the impact of micronutrients on marine carbon cycling. This Town Hall will introduce IDP2021\, explain how to access IDP2021\, and include some highlights on the use of GEOTRACES data. The goal is to intensify collaboration within the broader ocean research community but also seek feedback from the community to help us improve future data products. \n\n\n\nLead Organizer: William Landing\, Florida State University\, wlanding@fsu.edu \n\n\n\nDate and Time: Friday\, 2/25/2022 11:00 AM to 2/25/2022 12:00 PM (US EST) Location: Room 02 \n\n\n\nProgramme: \n\n\n\n\n– IntroductionBill Landing (Florida State University\, USA) \n\n\n\n– Introduction to GEOTRACES and to the GEOTRACES Intermediate Data Product 2021 (IDP2021)Catherine Jeandel (LEGOS\, Université de Toulouse\, CNES/CNRS/IRD/UT3\, Toulouse\, France)– Accessing the IDP2021Reiner Schlitzer (Alfred Wegener Institute (AWI)\, Bremerhaven\, Germany)– Education: Working with IDP2021 and webODV Explore toolPhoebe Lam (University of California\, Santa Cruz\, USA)– Exploration: Linking TEI and genomics data in IDP2021Maite Maldonado (University of British Columbia\, Vancouver\, Canada)– How can researchers register data for next IDP – The DOoR PortalBill Landing (Florida State University\, USA)– Q&A with speakersChaired by: Bill Landing (Florida State University\, USA) / Catherine Jeandel (LEGOS\, Université de Toulouse\, CNES/CNRS/IRD/UT3\, Toulouse\, France) \n\n\n\n\n \n\n\n\nGEOTRACES sessions:\n\n\n\nCT01 Temporal Variability of Bioactive Trace Elements in the Ocean: Towards Constraining Drivers\, Mechanisms and Timescales \n\n\n\nOrganizers:Peter Sedwick\, psedwick@odu.eduErin Black\, erinb@ldeo.columbia.eduAlessandro Tagliabue\, a.tagliabue@liverpool.ac.ukSimon Ussher\, simon.ussher@plymouth.ac.uk \n\n\n\nIn the past decade\, our understanding of the distribution of bioactive trace elements has improved greatly\, advancing the development of numerical models that provide mechanistic insight and predictive capability. However\, in addition to establishing the spatial distribution of biologically active trace elements\, it is equally important to understand their temporal variability. Such information provides critical constraints on the mechanisms that control the biogeochemical cycling of these elements\, and allows the assessment and expansion of numerical modeling efforts. In this session\, we invite interdisciplinary contributions from both observationalists and modelers that examine the time variation of bioactive trace elements in the ocean\, from both chemical and biological perspectives\, over timescales ranging from daily to millennial. \n\n\n\nCT03 Advances in understanding of the biogeochemical processes shaping the basin-scale distributions of trace elements and their isotopes \n\n\n\nOrganizers:Tim Conway\, tmconway@usf.eduLauren Kipp\, kipp@rowan.eduJessica Fitzsimmons\, jessfitz@tamu.eduGreg Cutter\, gcutter@odu.edu \n\n\n\nA range of important trace elements act as micronutrients\, toxins\, or tracers throughout the global oceans. The distributions of these trace elements are shaped by a range of biotic and abiotic processes including external sources and sinks\, microbial uptake and regeneration\, exchange with particles\, and physical circulation of the oceans. In recent years\, field programs such as GEOTRACES\, CLIVAR\, and SOLAS have hugely expanded the available datasets of trace elements and their isotopes (TEIs) throughout the oceans. These and other datasets are being used to determine the processes\, sources\, and sinks that control observed TEI distributions\, and the transformations and rates of input\, removal\, and exchange associated with each process. Here\, we invite submissions of abstracts using ocean transect\, field\, laboratory\, or modelling datasets that focus on the distribution\, isotopic composition\, speciation\, and cycling of TEIs at the basin-scale\, as well as abstracts which use geochemical tracers to interrogate the internal cycling and source/sink processes which shape these basin-scale distributions or transform TEIs within the ocean. In addition to studies that yield insights into the current distributions and cycling of TEIs\, we also invite submissions that investigate how the oceanic cycling of TEIs may change in response to the changing oceans and warming climate. \n\n\n\nCT10 Sources\, sinks\, and cycling of trace elements in coastal and near-shore systems \n\n\n\nOrganizers:David Janssen\, janssen.davej@gmail.comVeronique Oldham\, voldham@uri.eduEmily Estes\, estes@iodp.tamu.edu \n\n\n\nThe terrestrial-ocean continuum regulates the delivery of trace elements to the global ocean; however\, important gaps remain in understanding the complex cycling of trace elements in coastal systems. Further\, coastal systems face significant pressure from anthropogenic climate change\, nutrient loading\, and inputs of environmental toxins. This session aims to connect GEOTRACES-style studies on distributions of trace elements with studies examining processes and cycling of trace elements in nearshore environments to better bridge the terrestrial-ocean continuum. We invite contributions examining the cycling of trace elements and their isotopes in rivers\, wetlands and estuaries; inlets\, marginal seas and inland seas; and the near-shore coastal ocean. Field\, laboratory\, and modelling studies of trace element distributions\, speciation\, biological transformations\, sources and sinks\, and pollution & remediation are welcome. We particularly encourage studies (1) on the transport of terrestrially-sourced metals and dissolved organic matter to near-shore environments; (2) on metal fluxes to and from shelf sediments; (3) linking processes regulating near-shore trace element availability and their impact on the biosphere; and (4) investigating natural and anthropogenic perturbations on trace element cycling in these systems. \n\n\n\nCT11 Mercury transformations in marine ecosystems \n\n\n\nOrganizers:Eric Capo\, eric.capo@hotmail.frAmina Schartup\, aschartup@ucsd.eduHeyu Lin\, heyu.lin@student.unimelb.edu.auLars-Eric Heimbürger\, lars-eric.heimburger@mio.osupytheas.fr \n\n\n\nMercury (Hg) is a naturally occurring element that has been mined and released by humans for millennia. Inorganic Hg is released by natural processes such as volcanic activity\, and also by human activities which have largely outweighed natural ones. We have known for half a century that methylmercury is naturally formed in marine sediment and water column from inorganic Hg and is a potent neurotoxicant. The majority of global methylmercury exposure for human populations is from marine ecosystems due to its bioaccumulation in predatory fish at levels that are a million times\, or more\, higher than seawater. Yet our understanding of abiotic and biotic Hg transformations in marine systems is still limited. A greater understanding of the microbial reactions and geochemical conditions conducive to the formation and degradation of methylmercury is needed to mitigate its impacts on the health of fish-consuming wildlife and human populations. This session invites presentations on Hg transformations in marine ecosystems. \n\n\n\nOB20 Towards BioGeoSCAPES: Linking cellular metabolism with ocean biogeochemistry \n\n\n\nOrganizers:Adrian Marchetti\, amarchetti@unc.eduYoshiko Kondo\, yoshikondo@nagasaki-u.ac.jpNaomi Levine\, n.levine@usc.eduDalin Shi\, dshi@xmu.edu.cn \n\n\n\nBioGeoSCAPES is an international program initiative aimed at integrating 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 on a changing planet can be achieved by combining detailed information on plankton (i.e.\, virio-\, bacterio-\, phyto- and zoo-) cell status\, biochemical processes\, and species interactions with intercalibrated measurements of nutrient fluxes\, concentrations\, and speciation (e.g.\, macronutrients\, including inorganic and organic carbon\, micronutrients and vitamins). We invite contributions describing research that can serve as inspiration for this nascent program. Appropriate abstracts could include: studies that integrate cellular metabolism through physiological and ‘omics approaches (e.g.\, genomic\, transcriptomic\, proteomic\, metabolomic\, metallomic\, lipidomic\, etc.) with biogeochemical measurements\, including fluxes; or studies that scale from the cellular to the ecosystem level through integrated field measurements or mechanistic models of interactions. With the COVID-19 pandemic significantly impacting field research opportunities\, we are particularly interested in laboratory and modelling studies that provide new insights into BioGeoSCAPES-related topics across different scales of time and space. \n\n\n\nHL11 Arctic Ocean processes\, progress\, and potential explored through synthesis supported research \n\n\n\nOrganizers:Laura Whitmore\, lmwhitmore@alaska.eduLaramie Jensen\, jensenla@uw.eduRyan McCabe\, rmccabe.ocean@gmail.com \n\n\n\nSession Abstract:The Arctic Ocean is changing rapidly as a result of global climate change at rates disproportionate to other ocean basins. Changes in stratification\, circulation\, and ice cover are giving way to a cascade of biogeochemical and ecological changes that are altering the character of the Arctic Ocean. These changes influence the global ocean by modulating freshwater export from the Arctic Ocean to the North Atlantic Ocean\, the transfer of chemical constituents\, and the connectivity of organismal populations. Because of continued annual sea ice coverage and accessibility barriers; data collection across small (seasonal) and larger (annual to decadal) timescales has been historically difficult. In order to elucidate and ultimately predict the impacts of climate change on the Arctic Ocean system a synthetic and trans-disciplinary effort is valued. In this spirit\, we encourage submissions across ecological\, chemical\, physical\, and geological sub-disciplines with special consideration to interdisciplinary approaches and to studies investigating spatial and/or temporal scales.

SUMMARY:Goldschmidt 2022
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 Goldschmidt2022 Conference will take place in Honolulu and also online. \n\n\n\nGEOTRACES and GEOTRACES-related sessions:\n\n\n\n12a – The interplay between terrigenous fluxes and the biological pump as reflected by trace elements and their isotopes in the oceans\n\n\n\nConveners:Adi TorfsteinHebrew University of Jerusalem \n\n\n\nZanna ChaseInstitute for Marine and Antarctic Studies \n\n\n\nThe importance of the oceanic biological pump as a modulator of atmospheric CO2 levels and global climate cannot be overstated\, yet\, some fundamental aspects of its dyanamics are still not well understood\, such as the quantitative and qualitative impacts of terrigenous inputs into the oceans. These include dust\, river outflow\, glacial meltwater\, submarine groundwater discharge (SGD)\, and other processes along the margins\, all of which impose strong controls over the efficiency of the biological pump. Constraining their rates\, sources\, sinks and role in biogeochemical cycles is critical for achieving a full understanding of the dynamics of the biological pump.Here we seek contributions that utilize trace elements and their isotopes to describe the following non-exclusive topics: 1) Quantification and characterization of terrigenous inputs (dust\, rivers\, SGDs\, etc.) into the oceans and their impact on the marine environemnt\, 2) Studies of temporal and spatial patterns of terrigenous fluxes and their interplay with marine productivity and export production\, 3) Macro and micro scale interactions between terrigenous material and organic carbon\, 4) New methodologies and approaches to studying the role of trace elements in the marine biological pump. \n\n\n\nThe submission of multidisciplinary studies is encouraged\, including applications of organic geochemistry\, radionuclides\, experimental and analytical isotope geochemistry\, modeling\, and trace element phase partitioning. In addition\, we welcome time series –based studies\, both in the modern oceans as well as paleo records. \n\n\n\n\n\n\n\n12d – The Role Of Trace Metal Speciation (Physical And Chemical) At Marine Geochemical Interfaces\n\n\n\nConveners: \n\n\n\nCatherine JeandelLEGOS (Université de Toulouse\, CNRS/CNES/IRD/UPS) \n\n\n\nRebecca ZitounGEOMAR Helmholtz Centre for Ocean Research Kiel \n\n\n\nHélène PlanquetteUniversity Brest\, CNRS\, IRS \n\n\n\nSylvia SanderGEOMAR Helmholtz Centre for Ocean Research Kiel \n\n\n\nWilliam M. LandingFlorida State University \n\n\n\nAndrea KoschinskyJacobs University Bremen \n\n\n\nTrace metals exhibit a wide range of chemical\, physical\, and biological reactivities (e.g. oxidation\, precipitation\, sorption\, complexation\, toxicity) depending on their chemical and physical speciation (e.g. ions\, ion pairs\, organic and inorganic complexes\, colloids\, suspended particles). Thus\, the speciation of metals is of great importance not only to substantiate the geochemical fate of trace metals in the world’s ocean but also to estimate their availability and toxicity to marine biota. Geochemical interfaces are of particular interest because they exert a great control on trace metal cycling\, fluxes\, and rates and a full understanding of trace metal speciation along these boundaries is necessary for a more holistic understanding of the fate of trace metals in the marine environment. However\, despite decades of marine trace metal research\, we are still lacking knowledge of the speciation along geochemical interfaces (i) in space and time; (ii) the underlying driving processes; and (iii) their role for the global marine biogeochemical element cycles. Geochemical interfaces include sediment-water and atmosphere-water boundaries as well as regions with physicochemical gradients of density\, redox conditions\, temperature\, pH\, or salinity\, such as hydrothermal systems\, ground water discharges\, deep sea environments\, estuaries\, and coastal embayments. \n\n\n\nThis session brings together transdisciplinary scientists\, exploring trace metal speciation at various marine geochemical interfaces. We encourage contributions relating to novel analytical tools\, modelling approaches\, and laboratory-based experiments. \n\n\n\n\n\n\n\n14b: “Transport of particle-reactive elements from estuaries to open ocean: role of boundary exchange and oceanic internal cycling”\n\n\n\nConvenors:Kai DengETH Zürich \n\n\n\nMilena HorvatJožef Stefan Institute \n\n\n\nJianghui (JD) DuETH Zürich \n\n\n\nIgor ŽivkovićInstitute Rudjer BoškovićJožef Stefan Institute \n\n\n\nJennifer L MiddletonColumbia University \n\n\n\nParticle-reactive metals such as rare earth elements (REE)\, thorium (Th)\, mercury (Hg) etc. and their isotopes are powerful tracers for investigating the ocean biogeochemical cycles and can be applied to track e.g. continental weathering input\, transport of water mass and particle flux\, and anthropogenic emissions. For their robust applications across space and time\, it is crucial to obtain a comprehensive understanding of the physical-chemical processes controlling the behaviors of individual particle-reactive elements; the emphasis is on exchange at ocean interfaces via e.g. rivers\, atmospheric fallout and benthic dynamics and on internal cycling via e.g. scavenging and remineralization. Such knowledge based on the modern ocean can: 1) help resolve the long-standing debate arising from conflicting records of multiple particle-reactive isotopic systems in the geological past; 2) predict how anthropogenic emission and climate change scenarios will affect the cycling of key trace metals (e.g. toxic monomethylmercury; MMHg) in marine ecosystems. \n\n\n\nThis session invites observational\, experimental and modelling contributions on the distribution\, speciation\, flux and controls of particle-reactive metals from estuaries to open ocean\, with a particular interest in the interaction between seawater/porewater (including colloids) and lithogenic/biogenic particles. Multi-disciplinary and multi-proxy studies and contributions on advances in geochemical proxy development and in determination of metal speciation are especially welcome. This session focuses on processes and fluxes in the modern oceans\, but submissions on paleo-oceanographic and paleo-environmental reconstructions are also welcome. Early career scientists are particularly encouraged to contribute to this session.
