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.

SUMMARY:2023 Chemical Oceanography (GRS)
DESCRIPTION:Gordon Research SeminarChemical Tracers in the Sea\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\nThe theme of this Gordon Research Seminar is a tribute to Wallace “Wally” Broecker’s Tracers in the Sea. 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 those of 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 towards improving our understanding of the “anthropocene”-\, holocene-\, and paleo-ocean. We welcome all chemical oceanography abstracts that engage creatively with this theme. \n\n\n\nVenue: Southern New Hampshire University\, 2500 North River Road\, Manchester\, NH\, United States \n\n\n\nApplications for this meeting must be submitted by June 17\, 2023. \n\n\n\nFor further information please see the event website: https://www.grc.org/chemical-oceanography-grs-conference/2023/ \n\n\n\nRelated meeting: Chemical Oceanography\, Gordon Research Conference: https://www.grc.org/chemical-oceanography-conference/2023/

SUMMARY:Goldschmidt 2023
DESCRIPTION:There is a very interesting programme at Goldschmidt 2023 (9-14 July 2023\, Lyon\, France and online)! \n\n\n\nA list of GEOTRACES and GEOTRACES-related sessions is below (scroll down to read the session descriptions). \n\n\n\nThe deadline for abstract submission is March\, 1st 2023. \n\n\n\nList of GEOTRACES or GEOTRACES-related sessions:\n\n\n\n\n\n\n\nTheme 13\, Chemistry and physical processes of the oceans and atmosphere: now and through time:\n\n\n\n13c – Marine trace element cycling from the estuaries to the open ocean (GEOTRACES) \n\n\n\n13h – Emerging insights into processes controlling elemental and non-traditional stable isotope paleoproxies in past and present oceans \n\n\n\n13d – Hydrothermal vents from discharge to biogeochemical impacts \n\n\n\n\n\n\n\nTheme 14\, Science and Society:\n\n\n\nIn order to support broad participation\, all abstracts submitted to this theme are free of charge\, and can be in addition to another abstract from the same presenting author in another theme. \n\n\n\n14a – Use of GEOTRACES data to understand biogeochemical processes in the oceans \n\n\n\n14d – Lessons learned in communicating geochemistry to non-scientific audiences \n\n\n\n14c – Geoscientists’ Little Helpers – small software tools with big impact \n\n\n\n14e – Initiatives to advance diversity\, equity\, and inclusion in geochemistry \n\n\n\n14b – Engaging with a variety of communities: a workshop-style session to discuss issues\, ideas\, and practical solutions for more effective outreach \n\n\n\n14f – History of Geochemistry \n\n\n\n\n\n\n\nSession Descriptions:\n\n\n\n13c – Marine trace element cycling from the estuaries to the open ocean (GEOTRACES)Kai Deng\, ETH ZürichHelene Planquette\, Univ Brest\, CNRS\, IRD\, Ifremer\, LEMARAnh Le-Duy Pham\, University of California\, Los AngelesJennifer L Middleton\, Columbia UniversityPierre Damien\, University of California Los AngelesMarion Anne Fourquez\, Mediterranean Institue of OceanographyTrace elements and their isotopes in the ocean play essential roles as regulators of ocean carbon production and marine biodiversity\, as well as tracers of circulation and particle transport. This session highlights three areas of recent research that need critical attention. (1) Observational\, experimental and modelling contributions on the distribution\, flux and controls of particle-reactive elements from estuaries to open ocean. These particle-reactive elements such as rare earth elements\, Th\, Pa\, Pb\, Po\, Be\, involve processes and fluxes that are relevant in both the modern and paleo-ocean. (2) The impact of small-scale physical processes\, including submesoscale (<10 km) and mesoscale (<100 km) circulation\, turbulent mixing\, and sea-ice transport and melting on bioactive trace metals (Fe\, Mn\, Co\, Ni\, Cu\, etc.). Observational datasets on trace metals relevant to these processes are rapidly accumulating and state-of-the-art ocean modelling can use these as targets or predict distributions in areas with sparse data coverage. (3) The Southern Ocean as a whole\, and the Indian Ocean sector in particular remains poorly observed for trace elements and isotopes. Presentations are welcome on the recent SWINGS (Southwest Indian GEOTRACES Section\, Jan-Mar 2021) cruise as well as other Southern Ocean or GEOTRACES expeditions that investigate all aspects of marine trace element cycling including biogenic uptake\, remineralization\, particle fate\, export\, and circulation transport. Submission relating to all three of these areas are encouraged\, and especially by early career scientists. \n\n\n\n13h – Emerging insights into processes controlling elemental and non-traditional stable isotope paleoproxies in past and present oceansDavid J Janssen\, EawagAdina Paytan\, University of California\, Santa CruzSusan H Little\, University College LondonJiawang Wu\, Sun Yat-Sen UniversityGert J. De Lange\, Geosciences UtrechtRuifang Xie\, Shanghai Jiao Tong University \n\n\n\nTrace elements and their stable isotopes can serve as powerful proxies for understanding the biogeochemical history of the Earth\, as indicated by the biogeochemical regulations on their distribution in the modern ocean. Combinations of concentration and stable isotope data are providing new insights into their cycling\, sources and sinks. Recent results from these proxies have demonstrated their potential to build mechanistic understandings of the processes driving local and global paleoenvironmental conditions. Advancements in analytical capabilities and coordinated programs such as GEOTRACES and the Sedimentary Geochemistry and Paleoenvironments Project\, building global datasets from modern and paleo settings\, are greatly expanding proxy potentials. These advances allow for refinement of paleoproxy applications\, and the opportunity to reassess and improve some of the assumptions and uncertainties still existing.This session aims to connect modern\, paleo and methodological development communities to better integrate understandings of the present-ocean into paleoproxy applications\, and to identify key uncertainties where further research is needed. We welcome contributions improving the understanding of the biogeochemical controls on stable isotope distributions including data from modern settings\, from global modelling studies\, from culture or leaching experiments\, from studies on preservation and isolation of signals in sedimentary archives\, and from novel multi-proxy approaches. We also recognize that the field of non-traditional stable isotope geochemistry requires expensive infrastructure and time-consuming analyses\, facts that currently limit the diversity of scientists within it and thus the discipline as a whole. We welcome studies demonstrating good practice to increase accessibility\, diversity\, equity\, and inclusion of the field. \n\n\n\n13d – Hydrothermal vents from discharge to biogeochemical impactsZvi Steiner\, GEOMAR Helmholtz Centre for Ocean Research KielAnna Lichtschlag\, National Oceanography CentreDavid González-Santana\, Universidad de Las Palmas de Gran Canaria (ULPGC)Ziming Yang\, Oakland UniversityNatascha Riedinger\, Oklahoma State UniversitySeafloor hydrothermal systems and submarine volcanoes are crucial for the marine environment as they return buried substances\, including metals and dissolved gases\, from the Earth’s interior to the ocean and thus\, over geologic times\, control the composition of seawater and provide essential elements to the biosphere. Process understanding of the fate of hydrothermal products and discharges\, including complexation and scavenging by hydrothermal particles can be used as tool for answering questions around the controls of hydrothermal systems\, their evolution and activity over time and their potential impact on ocean productivity. This session will explore the fate of hydrothermal products and discharges proximal and distal to hydrothermal sources\, the diagenetic and microbial processes they undergo after deposition\, and their impact on the marine environment. We invite observational\, experimental and modelling contributions\, new approaches and new methodologies for shallow and deep hydrothermal systems from present and past times. We encourage submissions that will give new insights into the evolution of a hydrothermal system\, organic-mineral interactions\, spatial distribution and fluxes of products and discharges and the diagenetic alteration of hydrothermal products. Finally\, there are many parallels between the impacts of marine vulcanism and ocean acidification which we encourage submitters to consider. \n\n\n\n14a – Use of GEOTRACES data to understand biogeochemical processes in the oceansWilliam M. Landing\, Florida State UniversityAngela Milne\, University of Plymouth \n\n\n\nWe invite poster submissions demonstrating how trace element and isotope data\, together with nutrient\, oxygen\, hydrographic and BioGEOTRACES data from the GEOTRACES Intermediate Data Product (IDP2021) are being used to understand the biogeochemistry of the oceans. You might have used GEOTRACES data to quantify or constrain the input\, internal cycling\, and removal processes that ultimately control the global distributions of trace elements and isotopes (TEIs)\, especially those that are involved in biological cycling processes. You might have used GEOTRACES data in your teaching or outreach efforts\, and we definitely solicit reports from those activities. We imagine a collegial and convivial session where we can enjoy learning more about the various ways GEOTRACES data are being utilized. \n\n\n\n14d – Lessons learned in communicating geochemistry to non-scientific audiencesElena Masferrer Dodas\, GEOTRACES International Project OfficeChrissy Wiederwohl\, Texas A&M UniversityWe invite submission of experiences and materials for engaging with and communicating geochemistry to non-scientific audiences: general public\, schools\, the media\, policymakers\, and other stakeholders. Geochemists and scientists in general\, are very often faced to the challenge of communicating and sharing their knowledge to different audiences in a way that it is understandable to them.This session has the double purpose of showcasing examples which could serve as source of inspiration and at the same time highlight effective strategies that geochemists could follow to successfully engage with a non-scientific audience. \n\n\n\n14c – Geoscientists’ Little Helpers – small software tools with big impactJie Xu\, Institut für Geowissenschaften\, Goethe Universität FrankfurtThomas Rose\, Goethe Universität Frankfurt and Leibniz-Forschungsmuseum für Georessourcen/Deutsches Bergbau-Museum BochumJesse B. Walters\, Institut für Geowissenschaften\, Goethe UniversitätMiguel Bernecker\, Goethe University FrankfurtWorking with data over the years results almost inevitably in self-made code snippets\, scripts or spreadsheets\, and sometimes even full-fledged programmes that optimise workflows\, reduce workload and significantly speed up daily tasks. Some of them make it to the public but most remain invisible\, hidden behind the outcomes of the research they are helping with. However\, many of them are not shy but did not have the possibility to shine\, yet. We provide a spotlight for them\, so that the scientific community may benefit. We welcome presentations about all kinds of self-made software that facilitate our research. The presented tools can be written in any programming language and be in any stage of their development. We aim to raise awareness of what is already out there\, to facilitate sharing of the tools and to foster collaborations for their development. \n\n\n\n14b – Engaging with a variety of communities: a workshop-style session to discuss issues\, ideas\, and practical solutions for more effective outreachGeorgia G Soares\, Penn State UniversityBonnie Teece\, University of New South WalesIndrani Mukherjee\, University of New South WalesErica V. Barlow (she/her)\, Pennsylvania State UniversityThere are significant barriers to the implementation and progression of education and outreach activities\, particularly in the practical aspects of how to begin creating a diverse network and in co-creating and designing the activities. These barriers are especially apparent\, for example\, where fieldwork and research are performed and for early career researchers (ECRs) setting up new connections. This workshop-style session has two parts. The first part will bring together expertise from across the world to explore practical (rather than theoretical) ways of executing meaningful and impactful activities. Several experts (or “big issue” guides) will facilitate interactive discussions surrounding outreach with a variety of different communities. Topics of discussion may include co-creating decolonised outreach activities\, engaging with indigenous communities\, creating activities that capture students and/or communities from low SES backgrounds\, disability-inclusive outreach and education\, and using newer\, less traditional mediums (podcasts\, film\, social media\, etc.). Experts will lead smaller group discussions during this interactive workshop-style session and share how they engage with communities\, including lessons learned\, and encourage participants to share their experiences during outreach. At the end of this part of the session we will come together\, and each facilitator will share the ideas and practical solutions discussed in their groups. The second part is a poster session where submitters can highlight their own efforts relating to outreach people are attempting to start\, are currently engaged in\, and/or are trying to progress. Poster submissions will also shape the specific topics and issues that experts will discuss during this workshop-style session. \n\n\n\n14e – Initiatives to advance diversity\, equity\, and inclusion in geochemistrySusan H Little\, University College LondonJennifer L Middleton\, Columbia UniversityLAlastair J M Lough\, University of LeedsPallavi Anand\, The Open UniversityGeochemistry is a uniquely varied discipline\, spanning Chemistry\, Earth\, Planetary and Environmental Sciences. However\, this disciplinary diversity comes with unique challenges to fostering a diverse and inclusive community\, partly linked to inequitable access to resources and the combination of lab-\, field- and office-based approaches that geochemical research requires. In this session\, we invite presentations that assess the obstacles that contribute to the under-representation of marginalized groups within geochemistry and that suggest best practices and innovative ideas to remove those obstacles. Topics may include\, but are not limited to: data relating to professional representation (e.g.\, in awards\, medals\, grants\, graduate programs\, high-level positions\, invited talks\, papers\, journal editorships); evidence of barriers to inclusion\, personal\, institutional\, or cultural; and novel strategies and best practices to identify and overcome these barriers (e.g.\, mentoring\, networks\, funding\, institutional initiatives\, national or international policies or schemes). Abstracts to this session will be free of charge and will not prevent the submission of an abstract to another theme as presenting author. \n\n\n\n14f – History of GeochemistryJérôme Gaillardet\, IPGPWilliam M. White\, Cornell UniversityGeochemistry was not born yesterday. For example\, the multiplication of advanced analytical tools that make our daily work so fascinating in 2022 result from centuries of incremental or transformative technological innovations\, as well as from a succession of conceptual advances in the fields of physics\, chemistry\, Mathematics and Ecology. Those roots tend to be forgotten\, and this is detrimental to the quality of our science\, and our understanding of it. This session aims to explore the historical roots of geochemistry along two main directions. First\, a direction where geochemistry is conceived as a practical science based on advanced analytics\, which are only the outcome of centuries of creative technological inventions\, developments and measurements. Secondly\, geochemistry as a conceptual framework inheriting centuries of advances in the understanding of the structure and properties of matter\, light\, and other critical concepts of the geological sciences in general. All contributors who want to share with us their insights on the historical roots of our science and their pedagogical implications are welcome. A priority\, if needed\, will be given to early career scientists without discrimination for institution\, race\, etc.

SUMMARY:ASLO 2023\, Aquatic Science Meeting
DESCRIPTION:Palma de Mallorca\, Spain \n\n\n\nResilience and Recovery in Aquatic Systems\n\n\n\nConcepts of resilience and recovery do not only apply to aquatic ecosystems but also to societies when faced with disruptions and crises. Past events have shown that adaptability and decisiveness are important keys to resilience and recovery. Disruptions are opportune moments for setting up strategies for management and recovery. Faced with the COVID-19 pandemic\, ASLO meetings have adapted by transforming the ASM 2021 Palma meeting to virtual with a positive attitude that in 2023 we will recover and meet in-person. \n\n\n\nWe will incorporate the theme of resilience and recovery in aquatic systems into the plenary sessions and encourage submissions that examine these topics and invite you to contribute special sessions on topics relevant to freshwater and marine ecosystems.   \n\n\n\nFor further information: https://www.aslo.org/palma-2023/ \n\n\n\nGEOTRACES and GEOTRACES-related sessions:\n\n\n\n**SS014 Atmospheric Supply of Soluble Trace Elements and Isotopes: Advances and Challenges\n\n\n\nRachel Shelley\, University of East Anglia (rachel.shelley@uea.ac.uk)Susanne Fietz\, University of Stellenbosch (sfietz@sun.ac.za)Alex Baker\, University of East Anglia (alex.baker@uea.ac.uk)Morgane Perron\, CNRS – Laboratoire des sciences de l’Environnement MARin (LEMAR) (morgane.perron@utas.edu.au) \n\n\n\nApproximately 50% of primary production occurs in the oceans. Iron (Fe)\, and other trace elements (TEs)\, are essential micronutrients as primary producers require Fe for carbon (C)\, nitrogen (N) and phosphorus (P) acquisition. However\, in vast areas of the ocean\, marine production is limited by insufficient Fe availability or by the scarcity of a combination of two or more micronutrient TEs. Therefore\, the availability of TEs\, particularly Fe\, exerts a fundamental control on marine biological activity\, from bacterial and primary productivity of phytoplankton through to the fisheries which ultimately depend on them. Micronutrient TEs thereby support marine ecosystem services and CO 2 sequestration in most ocean basins and over various timescales. Atmospheric deposition provides an external source of TEs to the surface ocean. Large deposition events can relieve micronutrient (co-)limitation through the partial dissolution of TEs from aerosols. However\, large deposition events are sporadic and currently poorly understood. This presents a challenge for predicting how ocean ecosystems will respond to changes in soluble TE fluxes in the future. Therefore\, it is vital that models are able to represent and reproduce current and past TE distributions in the ocean in order to improve predictive capabilities. A further challenge is understanding how the different chemical compositions and atmospheric processing of natural and anthropogenic particles impacts TE solubility following deposition to seawater and\, thus\, the ability of biota to assimilate the TEs. Although mineral dust is proportionally the largest source of aerosol TEs to the global ocean\, anthropogenic and wildfire aerosols have a greater ability to dissolve in seawater. This results in the liberation of a larger fraction of bioaccessible TEs\, due to several factors. Following aerosol deposition\, new resource competition among primary producers can alter community structure and dynamics\, which influences the capacity of the ocean to sequester CO 2 \, fix nitrogen and produce biological gases which readily form cloud condensation nuclei. All three features exert crucial climate feedbacks. The degree to which autotrophs or heterotrophs are stimulated or suppressed by atmospheric deposition depends on the physicochemical form in which atmospheric TEs are delivered to seawater and on the initial nutrient status of the water. Again\, highlighting the need for a more integrated understanding of biogeochemical cycling including the atmospheric component. In this session\, we would like to invite submissions from novel experimental and modelling work on TE biogeochemistry at the air-sea interface. Presentations addressing key research questions including the controls on dissolution and/or uptake of aerosol TEs\, as well as modelling estimates of aerosol TE deposition fluxes in the present\, past\, or future are welcomed. Studies focusing on the Southern Hemisphere and other historically under-studied oceanic regions are particularly encouraged. This session has broad applicability to different research communities\, e.g.\, climate change\, human health\, fisheries\, and paleoclimate. As such\, we welcome cross-disciplinary submissions which address questions about the flux of TEs across the air-sea interface and the associated impact on marine ecosystems. \n\n\n\n**SSO38 Trace Metal and Macronutrient Behaviour in Large Rivers and Estuaries \n\n\n\nAdrienne Hollister\, Jacobs University Bremen (a.hollister@jacobs-university.de)Hannah Whitby\, University of Liverpool (hannah.whitby@liverpool.ac.uk)Rebecca Zitoun\, GEOMAR Helmholtz Centre for Oceanographic Research (rzitoun@geomar.de)Juan Santos-Echeandía\, Spanish Institute for Oceanography (juan.santos@ieo.csic.es) \n\n\n\nRivers are a major source of trace metals\, macronutrients and organic matter to the global oceans. Processes such as colloidal flocculation\, particle adsorption-desorption and biological activity influence the concentrations and speciation of trace metals and nutrients during estuarine mixing\, and therefore their overall behaviour and flux to the ocean. Major rivers such as the Amazon are becoming increasingly vulnerable to anthropogenic impacts\, including land use change\, hydroelectric dams\, metal pollution (e.g. from mining)\, plastic pollution (relevant as metal vectors)\, and agricultural runoff. These and other anthropogenic impacts to a river’s catchment area can lead to potentially toxic concentrations of metals (e.g. Cu\, Zn\, Pt\, Hg\, Pb\, Fe)\, or of macronutrients leading to eutrophication. In addition\, climate change is projected to cause both increased droughts and flooding\, resulting in changes in river flow and chemical output. These changes may have a drastic effect on trace metal and nutrient sources\, cycling\, transport\, fluxes\, reactivity and sinks at the land-ocean interface. As climate and land use changes amplify\, it is essential to establish a baseline for riverine trace metal and nutrient concentrations and fluxes to the ocean and sediments\, and to understand how these parameters may change with changing environmental conditions. Generally\, this session aims to evaluate the behaviour\, fluxes\, sources and sinks of trace elements and their isotopes (TEI) as well as macronutrients (N\, P\, Si) from major rivers to the ocean. Contributions focused on observational\, experimental\, and modelling approaches regarding metal- and nutrient cycling\, their chemical and biological transformation and distribution in rivers and estuaries are welcome. \n\n\n\nPosters\, presentations and hybrid presentations are welcome.  \n\n\n\n \n\n\n\nTown Hall\n\n\n\nSCOR Working Group 167\, RUSTED\, invites you to a Town Hall in the Sala Santa Catalina\, Palau de Congressos\, Palma de Mallorca at 13:30 on Wednesday 7 June 2023. \n\n\n\nConstraining the fluxes of micronutrient and pollutant trace elements (TEs) across the air-sea interface is a research priority of large international programmes such as SOLAS and GEOTRACES. RUSTED (Reducing Uncertainty in Soluble aerosol Trace Element Deposition) is the new SCOR Working Group 167. Our overarching objective is to assure the quality of TE solubility data produced from aerosol dissolution experiments and to improve the handling of such data in Earth System models. \n\n\n\nThe purpose of the Townhall is to: 1) introduce RUSTED to the Aquatic Sciences community\, 2) invite aerosol TE data contributions for inclusion in a new database and 3) assess research interests and understand barriers to participation in a workshop planned for 2025. \n\n\n\nBeyond improving understanding of air-sea biogeochemical exchanges\, RUSTED outcomes will be a valuable resource for other fields\, such as health and climate research. This Townhall will provide a unique opportunity to network with RUSTED members. \n\n\n\nFurther information about RUSTED is available here: https://www.geotraces.org/new-scor-working-group-rusted/

SUMMARY:EGU General Assembly 2023
DESCRIPTION:The EGU General Assembly 2023 (23–28 April 2023\, Vienna\, Austria and online) 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\n\n\n\n\nGEOTRACES session: \n\n\n\n\n\n\n\nOS3.1\, Response of ocean biogeochemical cycles to past\, present and future climate changeConvener: Alessandro Tagliabue | Co-conveners: Charlotte Laufkötter\, Christopher Somes\, Camille Richon \n\n\n\nhttps://meetingorganizer.copernicus.org/EGU23/session/45681 \n\n\n\nAbstract submissionClimate induced alterations to net primary production act alongside changes to biogeochemical cycling of oxygen and nutrients to affect marine ecosystem structure and function\, as well as the ocean carbon cycle on decadal to centennial timescales. Climate change is driving alterations to these key components of ocean health\, both via long term changes and the emergence of extremes. The 6th Climate Model Intercomparison Project provides new opportunities to analyze the long-term changes in biogeochemistry under different emissions scenarios\, as well as to explore the emergence and potential impacts of extremes. Additionally\, historical variability linked to climate oscillations such as ENSO and the Southern Annular Mode provide an opportunity to bring insights from observed changes and impacts. Moreover\, isotope systems and proxies are often used in paleoclimate and paleoceanography across geologic timescales of climate change to interpret past environmental changes in Earth’s history. Their interpretation relies heavily on these isotope systems’ budget in the ocean. \n\n\n\nThis session invites submissions\, from both observations and modelling efforts\, that address the impact of climate change operating over multiple timescales on net primary production\, biogeochemical cycling of nutrients and oxygen\, and the ocean carbon cycle\, including cascading effects for marine ecosystems to modulate biodiversity and ecosystem services.

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.

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.
