SUMMARY:ASLO 2018 Summer Meeting
DESCRIPTION:Association for the Sciences of Limnology and Oceanography (ASLO) 2018 Summer Meeting Dates: 10 -15 June 2018Location: Victoria\, BC\, Canada \nFurther information: https://aslo.org/victoria2018/main \nGEOTRACES-related sessions: \nSS82: EMERGING MODELS OF TRACE METAL BIOAVAILABILITY TO AQUATIC ORGANISMS \nDavid Semeniuk\, Minnow Environmental Inc. (dsemeniuk@minnow.ca)Randelle Bundy\, University of Washington (rbundy@uw.edu)Anne Cremazy\, U. British Columbia (acremazy@zoology.ubc.ca) \nWell established equilibrium-based trace metal bioavailability models for aquatic organisms (e.g.\, the Free Ion Activity Model and Biotic Ligand Model) have proven useful for predicting the bioavailability and toxicity of metals in aqueous environments for a variety of organisms\, from phytoplankton to fish. These models propose that metal bioavailability is proportional to the concentration of the free metal ion in solution. Thus\, given enough information about the chemical environment\, one can predict metal bioavailability and potential toxicity. Yet\, emerging laboratory and field studies indicate that these models do not accurately predict metal bioavailability under all environmentally realistic conditions\, such as when salinity and pH varies\, when natural organic ligands and bioavailable metabolites are present\, and at low trace metal concentrations (as opposed to high concentrations typical of industrial effluents). In light of this\, this session seeks new work that explores modified or alternative models for trace metal bioavailability to aquatic organisms\, and their ecological implications. We invite research concerning both experimental and biophysical chemical modeling of trace metal bioavailability\, including the roles of chemical speciation\, kinetic controls on metal bioavailability\, and the influence of metal and organic ligand mixtures on metal speciation\, bioavailability and toxicity.

SUMMARY:Introduction to the Awesome OCIM
DESCRIPTION:Introduction to the Awesome OCIMDates: 12 August 2018Location: Boston\, USA \nDownload the annoucement as pdf \n  \nIntroduction to the Awesome OCIM \nWorkshop\, August 12 th\, 2018\, MIT campus\, Boston MA\, 10 AM to 5 PM (Sunday preceding Goldschmidt 2018) \nContact sethjohn@usc.edu by June 1st to register\, including a few sentences about who you are and why you would like to attend. \n\nThe Awesome OCIM is a new modeling toolbox designed to bring cutting-edge transport matrix models to a wide community of users. This workshop will introduce the AO to the GEOTRACES community and the wider community of chemical oceanographers. Modeling novices welcome!  \nThe AO uses Ocean Circulation Inverse Model (OCIM) transport for realistic global 3d circulation. Within this circulation\, broad features of the distribution of many marine TEIs can be achieved by combining just a few processes. For example\, iron might be modeled as a combination of atmospheric and sedimentary sources\, biological uptake\, and remineralization. Thorium might be modeled with radioactive production and decay\, plus scavenging. A clickable interface allows the user to include processes such as these\, and tune their magnitude to match observed GEOTRACES data. Further adjustments to biogeochemical cycling can be achieved with changes to the underlying Matlab code. \nThis workshop is designed for graduate students\, postdocs\, and faculty with an interest in learning more about the AO. No previous experience with modeling is necessary. All participants will be given the latest version of the AO software\, and talks will include examples of how the AO and other similar OCIMs are used in research\, an introduction to using the AO through the GUI and underlying Matlab code\, and a hands-on opportunity to recreate the global distribution of your favorite TEI using the AO. Also there will be sandwiches. \n \n\n\n\n \n \n\n\n\nExample Graphical User Interfaces (GUIs) for running the AO and plotting model output with the AO. The behavior of many TEIs in the ocean can be approximated by combining a few key processes such as dust and hydrothermal inputs\, biological uptake and remineralization\, radioactive decay\, scavenging\, etc. Both GEOTRACES data and model output can then be plotted using a separate GUI. \n \nAn example of model output for a “cadmium-like” tracer with uptake and remineralization similar to PO4. This figure illustrates the 2° latitudinal and longitudinal resolution of the AO\, with 24-box depth resolution.

SUMMARY:Goldschmidt 2018
DESCRIPTION:Goldschmidt 2018Dates: 12 – 17 August 2018Location: Boston\, USA \nFor further information: https://goldschmidt.info/2018/index \nAbstract submission deadline: 30 March 2018 \nGEOTRACES session: \n \nSession 07i: New Insights in Marine Trace Element Biogeochemistry \nConveners: Christian Schlosser\, Florian Scholz\, Rene Boiteau\, Tim Conway\, Daniel Ohnemus\, Jennifer McKay\, William Homoky and Jessica Fitzsimmons. \nThe cycling of trace elements in the ocean is strongly influenced by a combination of biotic and abiotic processes including biological utilization\, water mass circulation\, sources and sinks\, and interactions with particles. Many trace elements are essential for life\, while others may be toxic pollutants. Therefore\, understanding the factors that control the distribution\, reactivity\, and bioavailability of these elements is important for predicting their effect on ecosystems and climate\, and for using them as tracers of ocean processes. Recent advances in oceanography have begun to clarify the unique sources and chemical forms of these elements throughout the ocean. Examples include better constraints on the cycling and sources of dissolved elements by isotopic analyses\, improved parametrization of benthic metal processes and fluxes in biogeochemical models\, revelation of particulate and colloidal metal phases by size-partitioned analyses\, and elucidation of siderophore\, humic\, and mineral forms of metals using novel applications of electrochemical\, mass spectrometric\, and x-ray spectroscopic methods. This session solicits submissions highlighting new findings about the processes that influence the marine biogeochemistry of marine trace elements and their isotopes in the past and present. We invite contributions that focus on the study of elemental isotope fractionation\, biological uptake and remineralization\, exchange processes at the sediment-bottom water and hydrothermal interfaces\, metal speciation and redox chemistry\, and biogeochemical modeling. Abstracts concerning new insights on elemental cycling from GEOTRACES ocean sections and process studies on the cycling of trace elements\, and any other works focused on understanding the transformations of metals from the molecular to global scale are strongly encouraged.  \nGEOTRACES-related session: \nSession 07l: Carbon Storage in the Ocean now and over Time \nConveners: Laura Robinson\, Gideon Henderson\, Christopher Hayes\, Barbel Honisch and Joe Stewart. \nKeynote speaker: Richard Zeebe (University of Hawaii) \nThis session invites contributions that relate to mechanisms through which the oceans cycle and store carbon. We welcome studies that consider the natural system’s capacity to store carbon today and over geologic timescales\, the rates of carbon cycle processes\, and the biogeochemical pathways involved in the carbon cycle. We also welcome efforts to examine modern day geoengineering of the ocean’s biogeochemical systems. \n  \nSession 07m: Sedimentary biogeochemical cycling along continental margins: role of climate\, tectonic setting\, and oceanographic regimes \nConveners:  Sian Henley\, Johan Faust\, Silke Severmann\, Robert Aller \nContinental margins are regions of intense diagenetic cycling\, sediment-water fluxes\, and burial of biogenic and lithogenic debris.  Margins are generally characterized by high biological productivity and sediment accumulation rates. However\, specific modes of benthic elemental cycling\, authigenic mineral formation\, and storage are strong functions of depositional environment\, including physical dynamics and sediment sources.  The effects of climate change\, such as decreasing sea-ice in the higher latitudes or changing precipitation patterns in drainage basins\, have the potential to greatly alter benthic cycling and the exchange between sediments and the water column.   This session will explore and contrast benthic biogeochemical cycling along continental margins from a range of climatic and weathering regimes (e.g.\, drainage basin weathering\, Corg reactivity)\, tectonic setting (active\, passive margins)\, sediment types (permeable\, impermeable)\, coastal processes (deltaic\, non-deltaic)\, and oceanographic conditions (e.g.\, upwelling\, ice cover\, ventilation – oxygenation\, tidal range). We particularly welcome contributions that focus on the origin\, processing\, fate\, and characterization of organic and inorganic carbon\, nutrients and metals within the context of modern climate\, oceanographic and ecosystem change.

SUMMARY:An Ocean of Opportunity
DESCRIPTION:An Ocean OpportunityDates: September 16-20\, 2019 Location: Honolulu Convention Center\, HI For further information: www.oceanobs19.net\n\n\n\n\n\n\n\n\n\n\n\n \n\n\n\n\n\n\n\n\n\n\n\nThe organizers of OceanObs’19 are soliciting abstracts of Community White Papers describing aspirations for the coming decade from all interested groups. The Community White Papers should promote international collaboration and large-scale sustained ocean observing efforts\, and address one or ideally more of the seven (anticipated) themes (Discovery\, Ecosystem Health & Biodiversity\, Climate Variability & Change\, Water\, Food\, & Energy Security\, Pollution & Human Health\, Hazards & Maritime Safety\, and Blue Economy) and two crosscutting themes on data information system and ocean observing governance topics. \nBased on the contributed abstracts of Community White Papers\, the OceanObs’19 Program Committee will solicit full Community White Papers to be submitted by end of September 2018. The Program Committee may recommend that authors of particular abstracts collaborate and merge the concepts described in separate abstracts to develop a joint Community White Paper. The papers will be peer-reviewed and published in an open access journal before the conference.  \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nWe seek abstract contributions that provide solutions to build and enhance connections between end users and ocean observations in relation to one or more of the conference themes.  Additionally\, abstracts should focus on (one or more of the following):   \n\nStrategies to address social and economic needs including the development of the Blue Economy;\nEmerging science concepts that require multidisciplinary sustained observations (i.e. biological\, biogeochemical\, physical\, geological\, social and economic\, etc.);\nThe value of existing ocean observations and their potential relevance in an evolving ocean observing system;\nThe requirements for sustaining and enhancing ocean observing capabilities;\nThe development of new observing technologies and networks\, including identification of new transformative directions for ocean observing;\nAdvances in open data\, information technology\, and governance systems;\nObservational or observation-model synthesis;\nThe need for improved processes to better support research and operations;\nInnovations in engagement with end-user communities.\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n \n\n\n\n\n\n\n\n\n\n\nCONFERENCE INFORMATION:\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nThe main goal of the conference will be to further develop effective strategies for a sustained\, multidisciplinary and integrated ocean observing system\, and to better connect user communities and observers. End user communities include operational users\, national and local authorities as well as researchers\, from the public and private sectors.  Engagement with international user communities can take diverse forms\, including closer interaction to better target their needs for ocean observing networks and derived products while better informing management decisions. OceanObs’19 will continue the tradition of building the vision of ocean users and observers.\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nBACKGROUND:\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nAs part of the decadal conference series\, OceanObs’19 will galvanize the ocean observing community ranging from scientists to end users. OceanObs’19 seeks to improve response to scientific and societal needs of a fit-for-purpose integrated ocean observing system\, for better understanding the environment of the Earth\, monitoring climate\, and informing adaptation strategies as well as the sustainable use of ocean resources.   OceanObs’99 resulted in an internationally coordinated system for physical climate and ocean carbon observations. OceanObs’09 expanded the range of communities working together to undertake more comprehensive ocean observations and led to the Framework for Ocean Observing. OceanObs’19 will seek to advance these outcomes by extending its reach the full spectrum of ocean communities.\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n \n\n\n\n\n\n\n\n\n\n\n\n\n\n\nExpected Schedule\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nDec 18\, 2018: Release of call for abstracts of Community White Papers March 15\, 2018:  Due date for abstract submission March 15 – April 30\, 2018:  Program Committee reviews and consolidates Community White Paper list April 30\, 2018:  Invitations to group authors for Community White Papers September 30\, 2018:  Community White Papers due\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nFor any additional information\, please reach out to info@oceanobs19.net or check out www.oceanobs19.net for up-to-date info!

SUMMARY:Fourth Xiamen Symposium on Marine Environmental Sciences (XMAS-IV)
DESCRIPTION:Fourth Xiamen Symposium on Marine Environmental Sciences (XMAS)Dates: 6-9 January 2019Location: Xiamen\, China \nFor further information: http://mel.xmu.edu.cn/conference/4xmas \n \nThe deadline for abstract submission is Aug 31\, 2018.  \nGEOTRACES session: \nThe role of trace metals in controlling structure and function of microbial communities in contemporary oceans  \nPunyasloke Bhadury\, Yeala Shaked\, Maria Maldonado\, Yihua Cai\, Chris Bowler \nTrace metals are essential for life\, catalyzing key cellular reactions that influence ocean productivity\, biodiversity\, and biogeochemical cycling of the major elements including carbon and nitrogen. Essential trace metals\, such as iron and zinc\, are usually present at very low dissolved concentrations in seawater and are mostly found as stable organic complexes. Indeed\, in large oceanic regions trace metals control the physiology and ecological functioning of microbial communities. There is a need to understand how microbial communities including nano and pico-phytoplankton acquire essential metals and how biological activity is affected by metal availability and resulting consequences for cycling of essential elements such as carbon\, nitrogen and phosphorus. To understand many of these questions\, large international research programs such as GEOTRACES have been initiated incorporating trans-disciplinary approaches to understand mechanistic links between geochemical and biological variability. In this session\, we welcome contributions from researchers\, including early career scientists\, investigating the role of trace metals on the structure and functioning of microbial communities including marine phytoplankton across ecosystems. In particular\, we welcome submissions in areas which address the link between trace metals and isotopes with a focus on microbial communities mediating the cycling of major nutrients in contemporary oceans\, metal uptake and competition between microbes for metal resources and the role of trace metals in shaping cellular function and evolution. \nSession ID: C3 [Bio-GEOTRACES]

SUMMARY:ASLO 2019\, Aquatic Sciences Meeting
DESCRIPTION:ASLO 2019\, Aquatic Sciences Meeting\nDates: 23 February – 2 March 2019\nLocation: San Juan\, Puerto Rico \nFor further information: https://aslo.org/sanjuan2019/main\n \n\nGEOTRACES sessions: \n\nSS51. New views on the biological transformation of metals in the marine environment \nRandelle Bundy\, University of Washington\nShane Hogle\, Massachusetts Institute of Technology\nKatherine Heal\, University of Washington\nKristen Buck\, University of South Florida\nP. Dreux Chappell\, Old Dominion University \n \nRecent results from the GEOTRACES program and other large-scale oceanographic surveys have provided compelling new insights into the distributions\, chemical speciation\, sources\, and sinks of trace metals. The bio-active trace metals such as iron\, copper\, cobalt\, zinc\, nickel and manganese are particularly compelling because they influence surface ocean primary productivity\, deep ocean carbon storage\, and atmospheric carbon dioxide concentrations in our modern earth system and over geologic timescales. There is still much to learn about the regeneration of bioactive metals from organic matter\, the influences of biological ligand production\, and the impacts of trace metal bioavailability in the ocean. Insights from recent biogeochemical studies have raised new questions related to the biogeochemical processes impacting the distributions of trace metals\, and novel methodological approaches are now revealing the molecular mechanisms that connect major bio-active trace metal cycles to the physiology\, ecology\, and evolution of marine microorganisms. However\, these techniques have only begun to be coupled with the wealth of existing geochemical knowledge afforded by existing large-scale programs. Here we welcome submissions relating to the cycling of bio-active trace metals\, particularly those using innovative techniques and novel modeling approaches. We also welcome studies from across temporal and spatial scales\, as well as experimental and modeling studies that bridge biological and geochemical cycling of trace elements. We hope this session will provide a forum for diverse scientific perspectives on the biogeochemical cycling of trace metals in the ocean. \n

SUMMARY:SOLAS Open Science Conference
DESCRIPTION:SOLAS Open Science Conference\nDates: 21-25 April 2019\nLocation: Sapporo\, Japan \nFor further information: https://www.confmanager.com/main.cfm?cid=2778 \n\nGEOTRACES Special Session:  \nAtmospheric deposition of iron\, ocean biogeochemistry and marine emission of biological aerosols \nConveners: Akinori Ito (JAMSTEC)\, William M. Landing (Florida State University) and Douglas S. Hamilton (Cornell University) \nAtmospheric deposition of aerosols to the ocean has been suggested to modulate marine primary productivity. Marine organic material has been shown to be an important source of ice-nucleating particles (INP) in high-latitude environments\, and hence impacts the atmospheric energy balance. Significant progress has been made in our understanding of atmospheric inputs of labile iron (Fe) from natural and anthropogenic sources to the surface oceans. However\, there are still large uncertainties regarding the relative importance of different sources of aerosols\, the effects of atmospheric aerosol deposition on bioavailable Fe concentrations in the ocean and on the marine organic material and its role as INP. The discussion in this session focuses on problems and challenges in laboratory experiments and field measurements to improve the representations of trace metal biogeochemistry in atmosphere and ocean models\, in particular\, the two-way movement of aerosol material across the boundary between the atmosphere and ocean.

SUMMARY:2019 Gordon Research Conference on Chemical Oceanography
DESCRIPTION:2019 Gordon Research Conference (GRC) and Seminar (GRS) on Chemical Oceanography\nDates: 13-19 July 2019\nLocation: Holderness School\, Holderness\, NH\, USA \nGRC: Discovering Chemical Processes and Mechanisms in a Changing Ocean \nThe study of ocean chemistry is central to the understanding of global biogeochemical cycling and human sustainability. Since this GRC conference began 50 years ago\, great progress has been achieved in the fundamental understanding of the chemistry of the oceans. Yet there is a great deal to be learned about how the chemical species and their inventories in the oceans interact with physical\, geological\, biological\, biochemical\, and chemical processes. Moreover\, there are now a myriad of anthropogenic influences that are also likely changing marine geochemical and biogeochemical cycles. \nThis conference will highlight the leading edge of research in chemical oceanography with a focus on elucidating key processes and discovering mechanisms relevant to understanding large scale biogeochemical cycles in the oceans. Topics will explore key chemical reactions that influence biogeochemical processes\, examine reaction rates and what controls them\, applications of biochemical approaches\, large scale observations\, modeling and synthesis\, deep-time changes in ocean chemistry\, fluxes across interfaces\, and developments in instrumentation. This conference aims to connect researchers united by a common interest in improving our understanding of the changing chemistry of the oceans\, and to catalyze future research in understanding the biogeochemical cycles of marine environments. \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. The GRS is chaired by two graduate students and will include an invited keynote speaker. \nDeadlines: \n\nApplications for the GRC meeting must be submitted by June 16\, 2019.\nApplications for GRS must be submitted by June 15\, 2019\n\nFor further information Gordon Research Seminar (GRS): https://www.grc.org/chemical-oceanography-grs-conference/2019/\nFor further information Gordon Research Conference (GRC): https://www.grc.org/chemical-oceanography-conference/2019/

SUMMARY:27th IUGG General Assembly
DESCRIPTION:27th IUGG General Assembly Dates: 8-18 July\, 2019Location: Palais des Congrès in Montréal\, Québec\, Canada \nThe 27th International Union of Geodesy and Geophysics (IUGG) General Assembly will be held July 8-18\, 2019 at the Palais des Congrès in Montréal\, Québec\, Canada. This is a special opportunity for participants from Canada and from around the world to come together and share their science and culture. 2019 marks the 100th anniversary of IUGG; we will look back on the accomplishments of the previous century of Earth and space science research\, and forward to the next century of scientific advancement. Join us for a host of scientific activities\, including special public lectures\, keynote Union lectures and a wide variety of themed sessions. \nIAPSO is sponsoring or co-sponsoring 31 symposia covering a wide range of topics\, including several two linking to biogeochemistry (see below) but also subjects such as marine plastics and ocean acidification. \nThe program details can be found at the Assembly’s website: http://www.iugg2019montreal.com/iugg-program.html. Deadline for abstract submission in February 18th 2019. \nGEOTRACES relevant sessions: \n \nP02 – PHYSICS AND BIOGEOCHEMISTRY OF SEMI-ENCLOSED\, SHELF SEAS\, AND COASTAL ZONES \nConvener: Peter Zavialov (Russia) \nCo-Conveners: Jianping Gan (China)\, Osmar Moller Jr (Brazil)\, Katrin Schroeder (Italy) \nDescription \nThis interdisciplinary symposium provides a joint forum for oceanographers whose research focuses on physical\, chemical\, and biological processes in coastal zones\, semi-enclosed and shelf seas of the World\, as well as their responses to climate change and anthropogenic impacts. These areas are often characterized by complex interactions between land\, ocean\, and atmosphere\, they exhibit rich dynamics driven by a variety of feedbacks and forcing mechanisms. Marginal seas and coastal areas are particularly vulnerable to climate change effects and anthropogenic stressors. Given their limited geographical extension and their sometimes constricted connection to the open ocean\, these environments often exhibit shorter timescales in their responses to external forcing: this is why they are widely recognized as natural “laboratories” for studying oceanic processes and interactions between the physical\, biogeochemical and climatic spheres. They also play an exceptionally important role in ecosystem services and socio-economic issues and require careful governance measures to avoid or mitigate environmental deterioration. \nGathering experts from different regions\, the symposium will give a global perspective of the topic through comparison and elucidation of similarities and differences. Contributions on different regions are invited\, related to themes such as innovative observational\, theoretical\, experimental and modeling studies of the hydrodynamics\, marine biogeochemistry (e.g.\, nutrient dynamics\, primary production\, acidification\, algae blooms) and the influence these regional seas and coastal zones exert on the adjacent basins/oceans and on the global scale. Studies of past\, present and future climate variability are welcome\, as well as interdisciplinary studies on the bio-physical interactions in semi-enclosed and shelf seas. \nP09 – MARINE BIOGEOCHEMISTRY THROUGH TIME: NUTRIENT\, TRACE METAL\, OXYGEN\, AND CARBON CYCLING IN THE PAST\, PRESENT AND FUTURE \nConvener: Kate Hendry (UK) \nCo-Conveners: Zanna Chase (Australia)\, Katja Fennel (Canada)\, Patrick Rafter (USA) \nDescription \nOcean biogeochemistry is undergoing significant changes\, with likely effects on primary production and ecosystem health from massive human perturbations of the global carbon and nitrogen cycles. Future projections are highly uncertain\, but unlocking drivers and effects of biogeochemical reorganizations in Earth’s past may hold clues. \nThe aim of this symposium is to explore recent developments in our understanding of marine biogeochemistry at the interface of different disciplines. Topics could include limitation of primary production by micro-nutrients and macro-nutrients; the role of ecological interactions at the scales of populations\, assemblages and ecosystems; boundary processes including sedimentary cycling\, inputs from rivers\, groundwater\, the cryosphere and atmosphere; and physical movement that influences nutrient distribution and light availability by turbulent mixing\, mesoscale eddies and large-scale ocean circulation. We welcome contributions that offer a broad perspective from a wide range of disciplines\, including studies that utilise and bring together paleoclimate archives\, modern oceanographic observations\, and models.

SUMMARY:Goldschmidt 2019
DESCRIPTION:Goldschmidt 2019Dates: 18 – 23 August 2018Location: Barcelona \nFor further information: https://goldschmidt.info/2019/ \nAbstract submission deadline: 29 March 2019 \nGEOTRACES sessions: \n \n10c: Arctic and sub-Arctic Processes: Understanding Changing Ocean Circulation and Biogeochemistry \nConveners: Núria Casacuberta\, Michael Karcher\, John Smith\, Lauren Kipp\, Christian März\, Robyn Tuerena \nResearch in the context of GEOTRACES and beyond has shown the value of using chemical tracers in seawater for documenting and understanding transient ocean processes. Tracer applications in ocean models have provided significant additional insights into physical oceanography and fostered the improvement of ocean models. Natural and anthropogenic tracers such as radionuclides\, gas tracers\, oxygen isotopes\, DOM\, etc. can facilitate a better understanding of circulation and mixing in high latitude regimes. With a focus on the Arctic Ocean and its adjacent seas we invite contributions dealing with chemical tracers as tools for investigations on the circulation within and exchanges between the Arctic and sub-Arctic Seas\, including the northern Atlantic and Pacific oceans. We encourage contributions on large-scale processes occurring over annual to decadal time scales\, that provide insight into dispersion pathways in the Arctic and sub-Arctic seas and tele-connections between Arctic circulation and the Meridional Overturning Circulation via the Arctic Loop Current. We especially encourage contributions combining modelling with tracer measurements. Questions to be addressed may include: • What can be learned about circulation and modification of water masses in the northern oceans based on tracer observations and modelling? • What are the elements of water mass dispersion that appear to be stable over timescales of years to decades\, and which are changing? • What are the governing physics and bio-geochemistry factors? • What are the most promising new tracers for the Arctic domain? • How can collaboration between observational tracer science and modelling be improved? \n10j: Biogeochemical Cycles of Low Oxygen Zones and their Response to Ocean Deoxygenation  \nConveners: Nicole Bale\, Darci Rush\, Ruifang Xie\, Tim Conway\, Insa Rapp\, Laura Bristow \nKeynote: Caroline Slomp (Utrecht University) \nObservations in the past decades have confirmed steadily declining dissolved oxygen concentrations in the subsurface oceans including coastal systems (coastal hypoxia) and open ocean oxygen minimum zones. Future expansion and spread of oxygen deficient zones in the ocean is predicted as a consequence of climate change\, and will result in major changes to marine biogeochemical cycles. These changes will impact sources and sinks of nitrogen\, phosphorus\, sulfur and redox-sensitive trace metals in the oceans\, with global effects on the biota that utilize these elements. This session seeks to bring together geochemical\, biological and physical scientists working on present and past low-oxygen environments\, in order to gain an integrated view of biogeochemistry in these systems. We thus invite submissions of field\, experimental and modelling studies focusing on major nutrients\, trace elements\, dissolved gases\, microbial ecology\, molecular biomarkers\, productivity and physical drivers in these systems. We encourage submissions focusing on (1) the distribution\, isotopic composition\, and speciation of macro- (e.g.\, N\, P\, S\, Si) and micronutrients (e.g.\, Fe\, Zn\, Cd\, Ni\, Cu) across the entire oxic-anoxic transition both in the modern ocean and the geologic past such as oceanic anoxic events\, (2) assessment of the marine sources and sinks of these elements from low-oxygen environments\, (3) N2O and CH4 production and emissions in low-oxygen systems\, and (4) the impacts of chemical and physical change on productivity and microbial pathways. Regional or global interpretations based on earth system models or large chemical datasets from programs such as GEOTRACES are especially encouraged. \n10k: Trace Metal Cycling and Radioisotope Tracers of Ocean Biogeochemistry (GEOTRACES)  \nConveners: Aridane G. González\, Hannah Whitby\, Amber Annett\, Emilie Le Roy \nThis session will highlight recent advances in marine trace element chemistry and the use of radionuclides as tracers in the marine system. In particular\, we focus on the speciation and ligand-binding reactions of trace metals\, and investigation of both micro- and macro-nutrient cycles and fluxes using natural and anthropogenic radionuclides. The GEOTRACES program\, which aims to map the world’s oceans for trace elements and their isotopes with unprecedented resolution\, has facilitated rapid progress in these research areas. Radioisotopes are becoming increasingly powerful tracers for studying the biogeochemical cycles of carbon\, nutrients\, trace elements and isotopes in the world’s oceans. These tracers can be naturally-occurring or anthropogenic\, with a wide range of half-lives allowing their application to a broad array of processes. Methodological advances and standardization (e.g. through GEOTRACES and RiO5) are contributing to increasing spatial coverage and temporal resolution of data of many marine radioisotopes. In order to understand the processes behind trace metal fluxes and export\, we must also understand the physico-chemical interactions and organic speciation of trace metals\, which play an important role in their biogeochemical cycling. The GEOTRACES effort has vastly increased the database of metal-binding organic ligand distributions\, demonstrating key features and distinct regional trends. However the identification of these ligands\, as well as their effect on the redox reactions and bioavailability of trace metals in natural waters\, are still largely unconfirmed. In this session\, we invite observational\, experimental and modelling contributions on the distribution and characterization of organic ligands in the ocean\, as well as their effect on the redox reactions of metals in seawater. In tandem\, this session brings together studies using radionuclides to investigate aspects of marine biogeochemistry from local to global scale: fluxes and export of particulate material\, sources and sinks of macro- and micro-nutrients\, elemental cycles at ocean margins (e.g. estuaries\, sediments\, hydrothermal vents\, air-sea interface)\, or rates of biological processes (e.g. biological export and remineralisation). Studies presenting advances in methodology\, novel applications of radionuclide tracers\, or using radioisotopes to quantify human impacts on ocean biogeochemistry are also welcome. \n08m: Wally Broecker: A Scientific Celebration of a Life in Geochemistry \nConveners: Sidney Hemming\, Edouard Bard\, Sigurdur Gislason\, Roberta L. Rudnick \nWally Broecker was a towering figure in geochemistry. His research themes that spanned many sub-fields of modern geochemistry\, notably radiocarbon dating (the topic of his Ph.D. thesis)\, chemical oceanography and atmospheric chemistry and their changes through time. He developed methods for dating and tracing processes in the Earth system and applied them to various natural archives such as sediments from the deep-sea and from lakes on land\, fossil corals from tropical islands\, speleothems from caves and varnish deposits from deserts. This allowed him to address myriad research questions\, including testing the orbital theory; determining paleo-hydroclimate in drylands and documenting abrupt climate change that involved coupling between atmosphere and ice-sheets dynamics and the general circulation of the global ocean.Wally became intensely interested in\, and worried about\, the fate of anthropogenic CO2 in the atmosphere\, ocean and biosphere and its consequences such as greenhouse warming and ocean acidification. He was among the first scientists to warn us about the negative aspect of global warming and pleaded for engineering solutions to capture and sequester fossil fuel CO2.Over his long and exceptional career\, Wally always had a powerful and positive influence on a large number of students\, post-docs\, collaborators and fellow scientists working in other institutions on all continents. This session is in honor of Wally’s legacy and in the spirit of his wide-ranging interests and generosity. \nIncludes the GEOTRACES talk: \nGEOTRACES: Inspired by GEOSECS to Investigate Trace Elements and their Isotopes in the Ocean Anderson R\, Francois R\, Frank M\, Henderson G\, Jeandel C & Sharma Mhttps://goldschmidt.info/2019/abstracts/abstractView?id=2019002892Wednesday 21 August 2019\, 10h15 \nGEOTRACES-related sessions: \n08f: The Role of Carbon in Regulating Climate States: Lessons from Earth’s Past \nConveners: Kate Littler\, Gerhard Kuhn\, Norbert Frank\, Thomas Chalk\, William Gray \nKeynotes: Jessica Tierney (University of Arizona)\, Robert (Bob) Anderson (LDEO – Columbia Univ.) \nThis session aims to bring together scientists from the proxy and model communities that study all aspects of past cold and warm states of the Earth’s climate system. We welcome model or proxy studies of biogeochemical cycles and climate change that bring new evidence to light of the concentration and movement of carbon between atmosphere\, biosphere\, oceans\, and sediments and its role in regulating the climate states. This is because Earth’s climate is strongly forced by the concentration of CO2 in the atmosphere on a number of different timescales and climate models rely on accurate information from carbon reservoirs to reconstruct our past and predict our future climate states. Therefore\, this session aims to gather work on reconstructing CO2 and/or its movements between reservoirs to narrow down on the primary mechanisms of climate change on geological timescales\, as well as divining our near future through past evidence of glacial CO2 changes\, long-term CO2 drawdown and release\, and major climate transitions. Submissions interrogating the nature of orbital scale climate variability from any period are strongly encouraged as well as those looking at modern processes of carbon regulation and uptake. \n10a: Silicate Alteration in Ocean Sediments and Synthetic Glasses: Process\, Consequence\, and Kinetics \nConveners: Wei-Li Hong\, Jianghui Du\, Isabelle Muller\, David A McKeown \nKeynote: Catherine Jeandel \nReverse weathering and alteration of silicate mineral-glass under low temperature is of fundamental importance in the source and sink of various elements\, planetary climate\, carbon cycling\, and considerations for long-term nuclear waste glass storage. Silicate glass stability is of concern to many scientific studies: basaltic glasses in geochemical systems\, nuclear waste glasses in their final repository\, and weathering of industrial or cultural heritage glass objects. These processes have been studied through field observations as well as by laboratory experiments. For example\, reverse weathering is known to acidify solution through the neo-formation of clay minerals\, which constitutes significant sinks for trace elements and alkalinity in the ocean and sediments. Weathering of marine silicate minerals\, on the other hand\, has been shown to buffer solution pH and promote the precipitation of authigenic carbonates by increasing alkalinity and the release of cations. The interaction of silicate glass and water has been investigated by laboratory leach tests that range from days to over 30 years. These leach studies have identified smectites concomitant with long-term glass stability at low leach rates\, as well as the common occurrence of rapid acceleration of glass alteration associated with zeolite formation at high temperatures or high ratios of glass surface area to leachant volume. Outstanding issues concerning silicate alteration that will be addressed in this session include: the impact on benthic fluxes of various elements in the ocean; the effect on the global elemental cycle and planetary climate; how the strength of these processes vary with time and space; the factors governing the formation of aluminosilicate minerals (such as zeolites and smectites)\, the associated kinetics during glass alteration and its modeling. The two keynote speakers will share their insights on how submarine weathering of lithogenic material affects benthic fluxes of macro- & micro-nutrients (Dr. Catherine Jeandel from LEGOS)\, and macroscopic to atomic scale silicate glass alteration (Dr. Stéphane Gin from CEA). \n  \n10h: The Oceanic Particle Flux and its Cycling within the Deep Water Column \nConveners: Maureen Conte\, Rut Pedrosa Pamies\, Phoebe Lam\, Henry Ruhl \nThe oceanic particle flux plays a major role in global elemental cycles\, the ocean uptake of carbon dioxide\, and the transfer of energy and matter to the deep ocean and sediments. The particle flux and its composition represent a dynamic balance between biological processes that generate large sinking particles in the upper ocean and particle cycling processes within the ocean interior that consume\, modify and produce new sinking particles\, including biologically-driven organic matter remineralization\, particle aggregation/disaggregation\, chemical scavenging\, and authigenic mineral precipitation. New observational platforms\, sampling methods and advances in chemical and molecular techniques (e.g.\, metabolomics\, metagenomics\, transcriptomics) allowing for expanded particle characterization are providing novel insights on particle flux transformations within the deep water column\, including the depth evolution of particle-associated microbial communities and the scavenging of dissolved and suspended materials associated with biological reprocessing of flux materials. Synthesis and modeling studies are providing increased understanding of linkages between ecosystem structure and global patterns in surface export and flux transfer efficiency to the deep ocean. This multidisciplinary session will bring together scientists under research themes related to geochemistry\, biology\, oceanography\, modeling and climatology to present the current status of our understanding of processes controlling the magnitude and composition of the oceanic particle flux\, its attenuation and transformation with depth\, and its coupling with associated biogeochemical cycles. Session presentations will describe novel findings and syntheses which\, in turn\, will highlight key knowledge gaps in the particle flux and its role in geochemical cycles. \n  \n12a: Hydrobiogeochemical Processes at the Sediment-Water Interface: Wetlands\, River Corridors and Coastal Zones \nConveners: Dipankar Dwivedi\, Xingyuan Chen\, Joseph Tamborski\, Valentí Rodellas\, Edward O’Loughlin\, Yamin Deng\, Virginie Sanial \nKeynote: Christof Meile (University of Georgia) \nTerrestrial-aquatic and surface-groundwater interfaces are transitional zones that play a vital role in controlling the exchange of water and chemical constituents between land and water systems. In terrestrial-aquatic interfaces (e.g.\, wetlands and lagoons) the movement of water and the biogeochemically catalyzed transformations of its constituents determine the mobility of nutrients and contaminants\, the emission of greenhouse gasses into the atmosphere\, carbon (C) cycling and sequestration in subsurface environments\, and the quality of water itself. Likewise\, groundwater-surface water interactions (e.g. hyporheic and porewater exchange\, terrestrial and submarine groundwater discharge) have long been recognized as an important component of the hydrological cycle and an essential pathway for the transfer of material (e.g. nutrients\, metals\, C\, and contaminants) to surface water bodies (e.g. coastal ocean\, streams\, lakes\, lagoons\, and wetlands). This session brings together studies focusing on hydrobiogeochemical exchanges occurring at terrestrial-aquatic and surface-groundwater interfaces\, and their impacts on freshwater and marine systems. We particularly welcome new contributions addressing i) geomorphological and hydrobiogeochemical processes (including redox dynamics and transformations of C\, nutrients\, metals\, and contaminants) occurring in wetland environments (sediments\, rhizosphere\, and water)\, coastal aquifers\, submarine groundwater discharge zones\, and hyporheic zones; ii) modeling of ecosystem processes; iii) the challenges of bridging across scales (e.g.\, molecular to landscape; regional to global-scale). Method-based contributions which address iv) omics and bioinformatics approaches for identifying microbial interactions\, and v) new methodologies and the combination of approaches to trace groundwater-surface water interactions and associated forcing mechanisms\, are also welcomed. \n  \n13f: Trace Elements Speciation: Novel Methodologies and Insights into Transformations Influencing their Global Biogeochemical Cycle \nConveners: Sylvain Bouchet\, Adrien Mestrot \nMany trace elements (TE) can be toxic (e.g.\, As\, Hg\, Sb) and/or essential (e.g.\, Cu\, I\, Se) for humans\, plants and wildlife. Some also play important roles in atmospheric processes\, e.g.\, S\, I and Br. To understand the biogeochemical cycle and effects of TE\, it is crucial not only to quantify them in environmental and biological compartments\, but also to determine their speciation. This entails the distribution of TE between specific chemical forms in term of electronic or oxidation state\, molecular structure or complexes formed with various ligands. Indeed\, the partitioning\, transport\, bioavailability\, bioaccumulation and toxic or beneficial effects of TE largely depend on their speciation. The goal of this session is to highlight recent advances (1) in methodologies\, using elemental\, molecular and/or spectroscopic techniques\, allowing the identification and/or quantification of TE species (2) in our mechanistic understanding of the biotic and/or abiotic transformations affecting TE species (e.g.\, alkylation/dealkylation\, oxidation/reduction\, colloid formation and sorption/desorption) and (3) in assessing fluxes of TE among aquatic\, terrestrial and atmospheric (eco)systems. Contributions to the session may include fundamental and applied research based on laboratory work\, field experiments and/or modeling approaches. Studies looking at the potential effects of on-going and future global changes\, such as climate change and eutrophication\, on the fate of TE and their species are also strongly encouraged. \n  \n13e: Radionuclides in the Environment: Modeling\, Experimental\, Scaling\, Controlling Chemical/Microbial/Hydrological Processes \nConveners: Peter H. Santschi\, Daniel Kaplan \nSince the onset of the Manhattan project\, fluxes of anthropogenic radionuclides through the environment increased. This has resulted in increased concentrations of a number of anthropogenic radionuclides in the various environmental reservoirs. Consequently\, there is a growing need to understand and predict the consequences of increased fluxes of anthropogenic radionuclide\, in relation to those of natural radionuclides. At the same time\, the input of both anthropogenic and natural radionuclides can provide us\, due to their radioactive decay\, with the ability to get insights into time and spatial scales of key chemical/microbial/hydrological processes. The objective of this session is increased understanding of biogeochemical processes that control radionuclide cycling and their consequences in natural and anthropogenic systems. The emphasis is on modeling\, experimental\, scaling\, controlling chemical/microbial/hydrological processes. Themes can include: 1) Radionuclide speciation in aquatic\, terrestrial and atmospheric compartments\, including particulate and colloidal phases\, and the role biological processes play in determining radionuclide mobility\, oxidation state and degree of organic complexation/chelation. 2) Radionuclides in environments that provide sinks of radionuclides in the geosphere\, including wetlands\, lake sediments and soils. 3) Controlling chemical/microbial/hydrological processes\, including dissolution from primary mineral or organic phases\, sorption and incorporation into secondary phases. \n  \n
