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: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: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: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: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:2018 Ocean Sciences Meeting
DESCRIPTION:2018 Ocean Sciences Meeting Dates: 11-16 February 2018Location: Portland\, Oregon\, USA. \nFor more information: http://osm.agu.org/2018/# \nGEOTRACES and GEOTRACES related Town Halls: \nRelease of new GEOTRACES Data ProductWednesday\, February 14\, 2018\, 12:45 PM – 01:45 PMOregon Convention Center – Oregon Ballroom 201 Room has changed! \nGEOTRACES\, an international study of the marine biogeochemical cycles of trace elements and their isotopes\, has released its second data product (IDP2017).  The new data product expands greatly on the first collection of results released in 2014 in two important ways: 1) by adding a substantial body data from new cruises and 2) by adding additional datasets not available in the 2014 data product from cruises across the five world Oceans (e.g. aerosols\, isotopes and biological parameters that support the emerging BioGEOTRACES initiative). This expanded set of parameters available in the IDP2017\, ranging across micronutrients\, contaminants\, radioactive and stable isotopes and a broad suite of hydrographic parameters used to trace water masses provides an unprecedented means to understand the role of trace elements in shaping the functioning of the Ocean system.  We invite everyone to this town hall to learn about accessing IDP2017 and how it can be used for interdisciplinary research and teaching applications: http://www.bodc.ac.uk/geotraces/data/idp2017/ \nOrganizers: Robert F Anderson\, Columbia University of New York; Alessandro Tagliabue\, University of Liverpool; Gregory A Cutter\, Old Dominion University and Maite Maldonado\, University of British Columbia. \nDeveloping a framework for trace element\, isotope\, and other biogeochemical research in the Gulf of Mexico and Caribbean SeaTuesday\, February 13\, 2018\, 12:45 PM – 01:45 PMOregon Convention Center – Oregon Ballroom 201 Room has changed! \nIn addition to their dynamical influence on the formation of the Gulf Stream\, the Gulf of Mexico and Caribbean Sea are strongly affected by continental margin processes such as major river inputs and significant submarine groundwater discharges. GEOTRACES studies have increasingly demonstrated the importance of ocean margins in affecting trace element and isotope (TEI) fluxes to the open ocean. Given the importance of these marginal fluxes for cycling of carbon and nutrients\, the Gulf of Mexico has been a regional focus for recent OCB activities. However\, these activities\, as well as the 2010 Deepwater Horizon oil spill\, have revealed major gaps in our understanding of how inputs to the shelf influence biogeochemical and biological processes in open waters\, especially with regard to TEIs. Most such Gulf studies have focused on the Louisiana and West Florida shelves\, with little attention to open waters and interactions with the Loop Current. The steering committees of US GEOTRACES and OCB are beginning a conversation devoted to TEI research in the Gulf of Mexico and Caribbean. We invite GEOTRACES\, OCB\, and other ocean scientists interested in these marginal seas to discuss processes of interest\, existing programs and data sets\, and potential steps forward. \nOrganizers: Alan M Shiller\, University of Southern Mississippi; Heather M Benway\, Woods Hole Oceanographic Inst.; Robert F Anderson\, Columbia University & Lamont-Doherty Earth Observatory; Angela N Knapp\, Florida State University; Benjamin S Twining\, Bigelow Lab for Ocean Sciences and Kristen N Buck\, University of South Florida \nUpdate on the Second International Indian Ocean Expedition (IIOE-2)Monday\, February 12\, 2018\, 12:45 PM – 01:45 PMOregon Convention Center – D135-D136 \nThe second International Indian Ocean Expedition (IIOE-2) was launched on December 2015 and it will run through 2020 and beyond. This session will provide an update on international research activities that are being undertaken and planned in IIOE-2 and also report on the outcomes of a recent US Indian Ocean Science Planning workshop. The session will also present the mechanisms for involvement of interested scientists in IIOE-2 activities. \nOrganizers: Raleigh R Hood\, Michael J McPhaden and Lynne D Talley. \nGEOTRACES and GEOTRACES related sessions: \nThe Behavior of Trace Elements and Isotopes in Different Ocean Basins: New Insights from Comparisons and ContrastsSession ID#: 28118 Wednesday\, February 14\, 2018\, 08:00 AM – 10:00 AM\, 02:00 PM – 04:00 PMPosters: Wednesday\, February 14\, 04:00 PM – 06:00 PM \nSession Description: \nRecent international programs such as GEOTRACES have been examining the biogeochemical cycling of trace elements and isotopes (TEIs) in the world’s oceans to reveal the mechanisms and rates affecting their concentrations\, distributions\, chemical forms\, and interactions with organisms. In addition to studies by individual investigators\, the accumulating results show many similarities\, but some surprising differences between ocean basins\, with a classic example being the regionally-specific Cd/PO4 relationships. In the same way that deviations from the Redfield ratio of N/P between ocean basins\, known since the 1970s GEOSECS program\, provide insight into nitrogen cycle processes\, what can we learn from the comparisons and contrasts of TEIs\, and what tools are needed to explore and test these observations? This session seeks presentations from the observational and modeling communities on lessons learned from inter basin TEI data sets with respect to inputs to\, cycling within\, and exports from the world’s oceans. In addition we invite contributions that consider how TEI distributions\, their chemical speciation\, and interactions with micro-organisms shape microbial community structure and productivity in various ocean basins. \nPrimary Chair:  Gregory A Cutter\, Old Dominion University\, Ocean\, Earth and Atmospheric Sciences\, Norfolk\, VA\, United States \nCo-chairs:  Adrian Burd\, University of Georgia\, Athens\, GA\, United States\, Jay Thomas Cullen\, University of Victoria\, Victoria\, BC\, Canada and Tung-Yuan Ho\, Research Center for Environmental Changes Academia Sinica\, Taipei\, Taiwan \nAbiotic and Biotic Retention\, Recycling\, and Remineralization of Metals in the OceanSession ID#: 23502 Monday\, February 12\, 2018\, 04:00 PM – 06:00 PM and Tuesday\, February 13\, 2018\, 08:00 AM – 10:00 AM Posters: Monday\, February 12\, 2018\, 04:00 PM – 06:00 PM \nSession Description: \nTrace metals shape both the biogeochemical functioning and the biological structure of oceanic provinces\, and considerable insight into trace metal distributions have been gleaned from international programs like GEOTRACES. To date\, observational and modelling efforts have mainly focused on modes of external metal supply from different sources. While this has yielded important advances\, we also know that metals undergo key internal transformations such as biotic uptake\, scavenging\, recycling\, and remineralization.  These internal transformations play crucial roles in shaping the biogeochemical cycling of metals by governing their bioavailability\, oceanic distributions\, and residence times. In this session we solicit presentations that address key questions regarding the abiotic and biotic processes regulating (i) the retention timescale for metals in the upper ocean\, (ii) surface ocean metal recycling and bioavailability\, (iii) the subsurface regeneration length scales for metals in the ocean interior\, and (iv) the role of mineral versus organic characteristics of sinking particles on metal scavenging.  We also seek presentations that provide insights into how these key questions are mediated by differing physico-chemical and microbial processes in contrasting ocean settings. Presentations showing insights from the diverse standpoints of biogeochemical oceanography and molecular ecology\, from both observational and modelling perspectives\, are strongly encouraged. \nPrimary Chair:  Philip W Boyd\, University of Tasmania\, Institute for Marine and Antarctic Studies\, Hobart\, Australia \nCo-chairs:  Kristen N Buck\, University of South Florida Tampa\, College of Marine Science\, Tampa\, FL\, United States; University of South Florida\, College of Marine Science\, St. Petersburg\, FL\, United States\, Jessica N Fitzsimmons\, Texas A&M University\, Department of Oceanography\, United States and Alessandro Tagliabue\, University of Liverpool\, Liverpool\, United Kingdom \nThe Dawn of BioGEOTRACES: Metal-Microbe Interactions in the OceanSession ID#: 27768Thursday\, February 15\, 2018\, 08:00 AM – 12:30 AMPosters: Thursday\, February 15\, 2018\, 04:00 PM – 06:00 PM \nSession Description: \nTrace metals are essential for life\, catalysing key cellular reactions which then govern patterns of ocean fertility and biodiversity. Fundamental in this regard are the ways in which ocean microbes acquire essential metals and how biological activity is affected by metal availability. Developments in this field are being led by advances in analytical chemistry\, nanotechnology\, molecular biology\, and bioinformatics\, as well as the expansion of ‘omics’-related observations of in-situ microbial communities\, and the advent of new high resolution geochemical data from the international GEOTRACES program. It is now timely to bring together insights from these different disciplines\, spanning observation and modelling approaches to better understand how microbial activity\, diversity and ecology is shaped by interactions with trace metals over different space and time scales. By linking across disciplines\, there is the potential to develop the mechanistic understanding required to inform the ecological and biogeochemical models we rely on for testing hypotheses and projecting the impacts of ocean change. We are specifically interested in contributions that address (i) metal uptake and competition between microbes for metal resources\, (ii) how microbes adapt their physiology to metal scarcity and varied supply and (iii) how trace metals shape cellular function and evolution. \nPrimary Chair:  Adrian Marchetti\, University of North Carolina\, at Chapel Hill\, Department of Marine Sciences\, Chapel Hill\, NC\, United States \nCo-chairs:  Maria Teresa Maldonado\, University of British Columbia\, Vancouver\, BC\, Canada\, Alessandro Tagliabue\, University of Liverpool\, Liverpool\, United Kingdom and Yeala Shaked\, Hebrew University\, Interuniversity Institute for Marine Sciences\,\, Eilat\, Israel \n  \nBiogeochemical Processes Across Oxic-Anoxic TransitionsSession ID#: 28621Monday\, February 12\, 2018\, 08:00 AM – 10:00 AM\, 10:30 AM – 12:30 PMPosters:  Monday\, February 12\, 2018\, 04:00 PM – 06:00 PM \nSession Description: \nA suite of metabolically and chemically important oxidation-reduction reactions occur through the transitions from oxic to anoxic regions of the ocean. These reactions drive nutrient availability and metal solubility\, as well as organic matter production\, consumption\, and preservation. As oxygen minimum and deficient zones expand\, redox reactions in low to no oxygen environments are becoming globally more important\, both for the nitrogen and carbon cycles and also for trace metals. Understanding such environments can provide an important analogue for ocean chemistry and microbial life in the Precambrian\, prior to the great oxygenation events. This session seeks to bring together geochemical\, biological\, and physical scientists working on low oxygen and anoxic regions\, in order to create an integrated picture of biogeochemistry in these environments. Presentations from observational\, experimental\, or modeling standpoints on nutrients\, trace elements\, dissolved gases\, isotope systematics\, microbiology\, biological productivity\, or physical drivers in these regions are all invited. We especially encourage submissions investigating the redox transition in the water column or sediments of restricted basins such as Saanich Inlet and the Black Sea\, as well as GEOTRACES and open-ocean studies of settings such as the Eastern Tropical Pacific\, North Atlantic\, and Indian OMZs. \nPrimary Chair:  Jeffry V Sorensen\, University of Victoria\, School of Earth and Ocean Sciences\, Victoria\, BC\, Canada \nCo-chairs:  Roberta Claire Hamme\, University of Victoria\, School of Earth and Ocean Sciences\, Victoria\, BC\, Canada and Tim M Conway\, University of South Carolina\, Columbia\, SC\, United States \nOcean Biogeochemistry and Air-Sea InteractionsSession ID#: 29651Thursday\, February 15\, 2018\, 02:00 PM – 04:00 PM and Friday\, February 16\, 2018\, 08:00 AM – 10:00 AMPosters:  Wednesday\, February 14\, 2018\, 04:00 PM – 06:00 PM \nSession Description: \nStudies of ocean biogeochemistry related to air-sea interactions are providing significant new information to help us understand a wide variety of physical\, chemical and biological processes in the oceans. There are many processes that link the surface ocean and the lower atmosphere\, for example\, the release of biogenic compounds as sources of cloud or ice condensation nuclei\, the deposition of natural and anthropogenic aerosols that can affect plankton communities\, the transport of airborne microbes that can alter the dynamics of proximal and distant ecosystems\, the biology\, chemistry and physics of the sea-surface microlayer (SML) as the interface through which all exchanges between the atmosphere and the ocean occur\, the enrichment of surfactants and other biogenic compounds in the SML that can affect gas exchange rates\, etc. Understanding these processes is crucial for improving the reliability of regional and global models and the evaluation of future scenarios. We welcome contributions on all aspects of the physics\, chemistry\, and biology of air-sea interactions\, including observations\, experimentation\, methodological or technical developments\, and theoretical and modeling efforts. \nPrimary Chair:  Francesc Peters\, Institute of Marine Sciences (ICM\, CSIC)\, Barcelona\, Spain \nCo-chairs:  William M Landing\, Florida State University\, Department of Earth\, Ocean\, and Atmospheric Science\, Tallahassee\, FL\, United States\, Oliver Wurl\, Carl von Ossietzky Universität Oldenburg\, Institute for Chemistry and Biology of the Marine Environment\, Wilhelmshaven\, Germany and Brian Ward\, National University of Ireland\, Galway (NUIG)\, School of Physics\, Galway\, Ireland \n  \nBridging Microbial\, Stable Isotope\, and Micronutrient Approaches to Marine Carbon and Nitrogen RecyclingSession ID#: 28316Monday\, February 12\, 2018\, 08:00 AM – 10:00 AMPosters:  Monday\, February 12\, 2018\, 04:00 PM – 06:00 PM \nSession Description: \nThe efficiency of the ocean’s biological carbon pump is determined by the physical transport and cycling of both macro- (N\, P\, Si\, S\, O) and micro-nutrients (e.g. Fe\, Zn\, Co\, Cu\, Cd\, Ni\, Mn\, Mo\, V\, B\, Se). However\, even as our capability to measure nutrient concentrations and their isotopes have expanded to include basin-scale datasets\, we continue to be challenged by new insights with respect to variable plankton and organic matter stoichiometry\, lateral nutrient transport fluxes\, ‘new’ vs. ‘recycled’ nutrients\, metal-organics complexation\, scavenging rates\, variable remineralization rates\, elemental residence times\, and more. Here we welcome submissions that address macro- and micro-nutrient cycling and their effects on sustaining the marine carbon (e.g. export production) and nitrogen (e.g. nitrogen fixation\, denitrification) cycles. A wide breadth of scales (meso\, regional\, basin\, global; paleo\, present\, future) and scientific approaches to these questions are encouraged including observational\, theoretical\, modeling\, and isotopic studies. Finally\, we encourage submissions that work to bridge oceanographic disciplines. \nPrimary Chair:  Patrick A Rafter\, University of California Irvine\, Irvine\, CA\, United States \nCo-Chair:  Robert T Letscher\, University of New Hampshire\, Earth Sciences\, Durham\, NH\, United States and Alexis Pasulka\, California Polytechnic State University \n

González\, Kristen Buck\, Tina van de Flierdt\, Walter Geibert\, Zhimian Cao\, Catherine Jeandel\, Yves Plancherel\, Phoebe Lam \nTrace elements and their isotopes (TEIs) in the ocean are critical for marine life\, regulating ocean biogeochemistry and carbon cycling. TEI distributions also provide insight into ocean ventilation and circulation\, redox states\, productivity and hydrothermal inputs in the present and the past. The GEOTRACES program\, which aims to map the world’s oceans for TEIs\, has facilitated rapid progress\, enabling a coherent picture of TEI cycling to emerge. Accordingly\, in celebration of the launch of the GEOTRACES IDP 2017 at Goldschmidt\, this session aims to bring together studies addressing pressing questions in marine biogeochemistry. We invite submissions on a range of marine biogeochemical themes: (1) Comparing the distribution\, isotopic composition and speciation of the trace metals (Fe\, Zn\, Cd\, Ni\, Cu\, Ba) with the major nutrients (e.g. C\, N\, Si) in order to draw parallels and contrasts\, and especially to determine the role of the Southern Ocean in creating pre-formed signatures. (2) Investigating the oceanic distribution\, composition and interactions of TEI-binding organic ligands\, and their role in metal redox cycling\, distribution and speciation. (3) Investigating how interactions with oceanic boundaries (sediments\, hydrothermal vents\, atmosphere)\, (4) How abiotic/biotic internal cycling influences the distribution of oceanic TEIs\, and investigating TEIs which trace rates and particle scavenging. (5) Integrating multi-proxy GEOTRACES datasets including circulation tracers in order to address longstanding questions in biogeochemistry and paleooceanographic proxy calibrations. We encourage submissions with culture and modeling work to interpret TEI distributions\, as well as submissions combining interactions of different phases (e.g. particulate and dissolved) and multi-element datasets. \n10g: Submarine Groundwater Discharge: Forms\, Delivery\, Timing\, Processes\, Pathways and Scaling of Biogeochemical FluxesTuesday 15 August PM \nConvenors: Hans Dürr\, Nils Moosdorf\, Michael Böttcher\, Hannelore Waska\, Jing Zhang\, Walter Geibert \nSubmarine groundwater discharge (SGD) is now an established factor in marine budgets of nutrients as well as trace elements and their isotopes (TEIs). SGD can form subterranean estuaries (STE) where fresh meteoric groundwater mixes with seawater circulating in the sediment. Processes in the STE and at the sediment-water interface strongly influence the resulting net fluxes to the near-shore. The magnitude\, speciation and spatial variability of these diffuse biogeochemical inputs can have multiple impacts on biological activity in coastal environments and marginal seas\, many of which are considered key areas for regional GEOTRACES projects. However\, the temporal and spatial dynamics of processes determining SGD/STE biogeochemistry are poorly understood\, attempts of upscaling SGD for regional- to continental budgets have been difficult\, and lag behind the development of large-scale hydrogeological models of SGD. We invite contributions by geochemists\, hydrogeologists\, biologists and geophysicists related to: biogeochemistry (experimental and modeling) of SGD/STE from deep aquifers to the sediment-water interface with regards to distribution\, speciation and function of constituents; the dynamics of key biotic and abiotic processes in the STE; resulting net fluxes of SGD of nutrients\, micronutrients and tracers in the near-shore and in marginal seas; the behavior of particulates and their associated TEI distributions along coastal circulation and land-ocean gradients; approaches and strategies that connect multiple temporal and spatial scales. Studies related to regional anthropogenic effects and climate change are also welcome. We expect this session to facilitate joint investigations and cooperation of the regional terrestrial\, marine biogeochemical and ocean/environmental sciences community. \n10h: Non-Conventional Stable Isotopes in the Ocean: Novel Applications\, Technological Advances and Future Applications Wednesday 16 August PM and Thursday 17 AM \nConvenors: Horner Tristan\, Pearce Christopher\, Philip Pogge von Strandmann\, Kathleen Scheiderich\, Juan Carlos Silva-Tamayo \nThe past twenty years have seen an explosion of interest in using non-conventional stable isotope systems (‘non-CHONS’) to understand the relationships between—and temporal evolution of—the input\, internal cycling\, and output of chemical species from the ocean. These isotope systems have proved to be key tracers of Earth’s biogeochemical cycles\, and have provided important breakthroughs in our understanding of chemical fluxes across the major ocean boundaries (e.g. rivers\, atmosphere\, boundary exchange\, hydrothermal vents) as well as (bio)geochemical processes operating within the ocean (e.g. biological uptake and release\, speciation\, scavenging). This session invites contributions that offer novel perspectives using non-conventional isotope systems and the processes that control their cycling between Earth’s major reservoirs in modern and/or past settings. Submissions that present new analytical tools or experiment-based approaches for studying the mechanisms of elemental and isotope fractionation during mineral-fluid interactions\, redox transformations\, or biological cycling are strongly encouraged\, as are those that demonstrate how these techniques can be used to quantify the flux and internal cycling of chemical species in the ocean through time. We also welcome contributions that offer novel perspectives by synthesizing existing data into new conceptual models\, or use isotopic tracer-based approaches to aid constraint of the fluxes of other biogeochemically-cycled elements\, particularly those that integrate over a wide range of spatial and temporal scales. \n10m: Insights into Ocean Processes Through the Application of Radioactive Tracers Tuesday 15 August PM and Wednesday 16 August AM \nConvenors: Paul Morris\, Guizhi Wang\, Virginie Sanial \nThe use of radioactive tracers to investigate ocean processes is an increasingly mainstream component of the techniques available to marine chemists. This so-called “nuclear toolbox” has seen continued development\, from better sampling and measurement technology to smaller sample volumes\, which has opened new avenues of investigation for studying ocean processes. While many of these radioactive tracers occur naturally in the environment\, ocean scientists can also use radioactive tracers released through human activities via intentional releases and accidental events. These radioactive tracers can be applied to a range of time-scales in both local case studies and basin-scale investigations that target both boundary and open-ocean processes. This session welcomes submissions that use radioactive tracers as a primary tool to investigate: (1) fluxes of particulate matter and dissolved materials\, (2) water mass mixing and mixing rates\, (3) processes that occur at the ocean boundaries (including coastline\, seabed\, and surface)\, and (4) studies that attempt to constrain geochemical budgets. Contributions that address method development\, novel applications of well-established tracers to new systems\, transport and fates of anthropogenic radionuclides in the ocean\, and issues that arise from the inherent integrating properties of radioactive tracers are also welcomed. \n10n: Nutrient Biogeochemistry in the Ocean: Past\, Present and FutureWednesday 16 August \nConvenors: Scott Wankel\, Sinhué Torres-Valdés\, Kimberly Popendorf\, William Haskell\, Christian März\, Damien Cardinal\, Wiebke Mohr\, C. Mark Moore\, Francois Fripiat\, Xingchen Wang\, Jia-Zhong Zhang \nThe availability of nutrients\, specifically nitrogen (N)\, phosphorus (P) and silicon (Si)\, exerts strong control on net primary production in the oceans\, the efficiency of carbon export from the euphotic zone\, and even the composition of the atmosphere. While the cycling of these elements is intimately coupled\, each elemental cycle possesses distinct characteristics regarding oceanic sources and sinks\, modes of internal recycling\, residence times and bioavailability. Indeed\, dynamics of individual nutrients diverge in important ways\, leading to formation of distinct regimes in both modern and past ocean systems. For example\, our understanding of specific processes (such as N2 fixation) has greatly expanded over the past two decades including delineation of new habitats\, description of new organisms\, and identification of new lifestyles. Nevertheless\, the relative roles of specific groups in various regions of the ocean\, their spatial and temporal variability\, and factors influencing their activity and distribution remain unclear. Furthermore\, while clear changes are often observed in response to contemporary climate change (including ocean warming\, acidification and deoxygenation)\, responses to such alterations and consequences for ecosystem functioning are far from understood. This session brings together new analytical and modeling insights to marine environments advancing our fundamental understanding of nutrients and their importance to the Earth system of the past\, present and future. We encourage submissions highlighting novel approaches (especially application of natural abundance and tracer-level stable isotopes) and those dealing with inter-elemental (de)coupling\, multiple spatial scales (cells to oceans)\, and/or multiple temporal scales – from geologic past to the future. \n17g: Paleoceanographic and Paleoclimate proxies: Their standing on Elderfield’s proxy development CurveThursday 17 August \nConvenors: Marie-Laure Bagard\, Marie Boye\, Oscar Branson\, Sambuddha Misra\, Guillaume Paris\, Kauzyo Tachikawa \nGeochemical proxies are essential tools to understand the evolution of seawater chemistry\, climate of the past\, and cycling of material between the different surface and deep reservoirs of the planet. Professor Henry (Harry) Elderfield helped develop numerous chemical tracers in the sedimentary record of ocean circulation\, isotope systems and seawater chemistry and temperature\, deeply influencing our understanding of chemical oceanography\, atmospheric interactions\, paleoclimate\, and biomineralization. Harry noted that a proxy develops through phases of optimism\, to pessimism and eventually to realism as our understanding of the applicability and limitation of a proxy evolves – the infamous ‘Elderfield Curve’. We invite submissions that critically evaluate or apply new and established proxies of past-climate and seawater chemistry and redox state\, how they are influenced by processes such as diagenesis\, and consider or alter their position on the Elderfield Curve. Contributions are invited from studies that utilize new (e.g. U/Ca; Na/Ca; Li/Mg ∂7Li\, ∆47) and established (e.g. Mg/Ca; B/Ca; ∂11B\, ∂18O\, eNd\, uk’37\,) proxies for paleoclimate and paleoceanographic studies\, including proxies used for deep time reconstructions (e.g. Fe-speciation\, ∂98Mo\, ∂53Cr). The focus will be on studies that outline novel and multi-proxy applications from a range of sedimentary phases\, investigate the mechanisms behind them\, notably through laboratory experiments and modern observations (GEOTRACES\, porewaters\, continental input\,…) or highlight possible limitations of established ones. \n

SUMMARY:IUPAC 2017 - World Chemistry Congress
DESCRIPTION:IUPAC 2017 – World Chemistry CongressDates: 9-14 July 2017Location: Sao Paulo\, BrazilFor further information: http://www.iupac2017.org/ \nAbstracts are due on January 8\, 2017 \nSession description: \nEnergy\, Water and Environmental Sciences (EE)http://www.iupac2017.org/symposia.php#ee \nNatural waters contain a large number of chemicals reflecting rapid global dissemination of novel substances\, including a full range of technology-critical elements (e.g.\, platinum group and rare earth elements) and emerging contaminants (e.g.\, PFAAs\, hormones and phthalates) employed to improve the production of energy and/or commodities\, especially due to the ever-expanding list of new technologies. The settlement of smart grids for electricity distribution together with the development of electric vehicles and renewable energy sources has enlarged a rising demand for advanced energy conversion and storage systems. Rechargeable batteries will continue to rely on Li-ion chemistry; however\, post Li-ion systems — such as Li-S\, Li-air\, Na-ion — are expected to reach the stage of devices. Also these developments are accompanied by the up growth of electrochemical capacitors\, fuel cells\, metal-air batteries. Solar cells\, biofuels\, water splitting\, hydrogen production and CO2 reduction are also important topics playing a leading role in the relation between energy and friendly environmental ways to assure a high efficiency of conversion and storage systems. To go further with sustainable technology\, the understanding of the fundamental concepts of materials properties and the interactions with their environment\, will be the key to find solutions which would satisfy the new society´s energy demands with a deep ecological concern. Therefore\, this symposium is devoted to recent progress in fundamental science related to rechargeable batteries and electrochemical capacitors\, fuel Cells\, metal-air batteries\, solar cells\, biofuels\, water splitting\, hydrogen production and CO2 reduction. Additionally\, this symposium will also focus on processes controlling the distribution\, fate\, bioavailability and environmental risks of technology-critical elements and emerging contaminants associated with the development of new products and technologies. \nSymposium Organizers: Roberto M. Torresi (IQ-University of São Paulo\, São Paulo\, Brazil – rtorresi@iq.usp.br) and Daniel Belanger (Département de chimie\, Faculté des Sciences\, University of Quebec\, Montreal\, Canada – belanger.daniel@uqam.ca).Co-organizer: Vanessa Hatje (CIEnAm- Universidade Federal da Bahia\, Bahia\, Brazil – vanessa@pq.cnpq.br) \nTopics \n5.7 Organic and inorganic contaminants in the environment: occurrence\, sources\, fate and impacts5.8 Trace elements cycling\, processes and fluxes across interfaces5.10 Environmental impact of emerging technologies (E-waste- an emerging global challenge and Global Environmental Challenges of Nanomaterials) \nConfirmed keynote speakers include: Antonio Cobelo\, Peter Croot\, Catherine Jeandel and Gideon Henderson \n

SUMMARY:2017 PAGES Open Science Meeting
DESCRIPTION:2017 PAGES Open Science Meeting Dates: 9-13 May 2017Location: Zaragoza\, Spain \nFor further information: http://www.pages-osm.org \nGEOTRACES session: \n12. Trace elements and their isotopes as geochemical proxies of past ocean conditions \nCo-conveners: Catherine Jeandel (catherine.jeandel@legos.obs-mip.fr)\, Robert Anderson (boba@ldeo.columbia.edu)\, Susan Little (s.little@imperial.ac.uk)\, Thomas Marchitto (thomas.marchitto@colorado.edu) and Daniel Sigman (sigman@princeton.edu). \nTrace elements and their isotopes archived in marine sediments\, corals\, microfossils\, authigenic minerals and other media have been exploited widely to reconstruct past ocean conditions\, including\, but not limited to: temperature\, nutrient concentrations\, ocean circulation\, biological productivity and export production\, dissolved inorganic carbon system parameters\, and external sources of material to the ocean\, for example as dust or via boundary exchange. Despite this importance\, many proxies of necessity have been calibrated in a rather ad hoc way. Many calibrations use samples that do not necessarily represent modern conditions\, or they have been calibrated solely in the lab. Calibration is often empirical and based on only partial understanding of the processes that relate the measurable proxy to the environmental variable that it encodes. \nThere is therefore an urgent need for more thorough assessment of geochemical proxies to fully understand the uses and limitation of present proxies\, and to develop and reliably calibrate new proxies for environmental variables that are presently difficult to reconstruct. The wealth of new and high-resolution trace element and isotope data generated by GEOTRACES as well as by contemporary initiatives offers an unprecedented opportunity to assess our understanding of geochemical proxies. This session invites presentations that exploit modern ocean observations of trace elements and their isotopes to critically examine and improve the application of geochemical proxies of past ocean conditions. \nInvited Speakers: Chris Hayes (Univ. of Southern Mississippi)\, Tristan Horner (WHOI)\, Kazuyo Tachikawa (CEREGE) and Jimin Yu (Australian National University).

SUMMARY:ASLO 2017\, Aquatic Sciences Meeting
DESCRIPTION:ASLO 2017\, Aquatic Sciences MeetingDates: 26 February – 3 March 2017Location: Honolulu\, Hawaii\, USA \nFor further information: http://www.sgmeet.com/aslo/honolulu2017/default.asp \n GEOTRACES sessions: \n004 – Biogeochemical Cycling of Trace Elements and Isotopes in the Arctic Ocean \nTrace elements can play a dual role in the ocean either as essential micronutrients (e.g.\, Co\, Fe\, Zn)\, or as toxicants (e.g.\, As\, Cu\, Hg)\, and can affect biological productivity\, carbon cycling and the emission of climatically important trace gases. In addition\, the distribution and isotopic composition of many trace elements and gases provide information on biogeochemical and physical processes. The Arctic Ocean\, in particular\, is undergoing rapid and profound transformation attributed to climate change. Easier access and accelerated resource exploitation are also expected in the coming years. It is therefore timely to examine more thoroughly the distribution and cycling of trace element and isotopes (TEI)\, and dissolved gases in the Arctic Ocean and to establish their potential role in controlling or recording rapidly changing oceanic processes. To that end\, after six years of collaborative planning\, the international GEOTRACES program undertook a coordinated study of TEIs\, dissolved gases\, and biological productivity in the Arctic in summer-fall 2015\, comprising three funded icebreaker programs from Germany\, Canada\, and the United States. This session seeks presentations on all aspects of this work and their relevance to Arctic Ocean processes from the GEOTRACES expeditions and other related field and laboratory efforts. \nORGANIZERS \nGreg Cutter\, Old Dominion University\, gcutter@odu.eduRoger Francois\, University of British Columbia\, rfrancoi@eos.ubc.caDavid Kadko\, Florida International University\, dkadko@fiu.eduWilliam Landing\, Florida State University\, wlanding@fsu.eduMichiel Rutgers Van der Loeff\, Alfred Wegener Institute\, Mloeff@awi.de \n  \n025 – Linking atmospheric deposition to the biogeochemistry of aquatic and marine systems \nAtmospheric deposition of lithogenic\, anthropogenic\, and marine aerosols is an important transport pathway for nutrients and contaminants to aquatic watersheds and the surface ocean. Constraining local\, regional\, and global atmospheric deposition fluxes and the bioavailability and toxicity of aerosol-sourced elements and compounds is essential to furthering understanding of global biogeochemical cycles. Aerosol emission\, transport\, and deposition processes are\, in part\, a function of changes in land use and anthropogenic emissions\, as well as short-term meteorological events and long-term climatic change on a global scale. Hence the study of system responses will improve our current understanding and facilitate the prediction of future impacts. This session invites contributions from studies of atmospheric deposition in marine and aquatic environments including\, but not limited to\, characterization of aerosol composition\, quantification of atmospheric deposition fluxes and aerosol fractional solubility\, assessment of the fate of aerosol-sourced compounds\, and the biological and chemical response to deposition. Contributions from global and regional scale field observations\, laboratory studies\, and modeling efforts are welcomed. \nORGANIZERS \nClifton Buck\, Skidaway Institute of Oceanography\, clifton.buck@skio.uga.eduRachel Shelley\, LEMAR-Universite de Bretagne Occidentale\, rachel.shelley@univ-brest.fr \n  \n029 – REE marine geochemistry in the 21st century: A tribute to the pioneering research of Henry Elderfield (1943-2016) \nHenry Elderfield had a long and multi-faceted career investigating the marine biogeochemistry of trace metals and his greatest accomplishment may be his groundbreaking measurements and interpretations of the oceanic distribution of rare earth elements (REEs). He helped revolutionize REE analysis of natural waters and produced some of the first vertical profiles in seawater by replacing painstaking chemical separations and neutron activation with isotope dilution mass spectrometry of 10 REEs together. In these days of automated in-line extraction and ICP-MS\, it is hard to recall the amount of time and effort involved in measuring picomolar REE concentrations just 30 years ago. To honor Henry’s memory we invite the next generation of aqueous geochemists to submit original work on REE cycling in the oceans. Our session will focus on the rapidly expanding dataset of REE concentrations and isotopic ratios from the GEOTRACES program and its use in the construction and testing of global marine mass balance and transport models. Studies of sources\, sinks\, and processes that create the boundary conditions for such modeling\, for instance particle scavenging and speciation\, hydrothermal and groundwater inputs\, and REE exchange in margin sediments\, estuaries\, and at the air-water interface are also welcome. \nORGANIZERS \nKaren H. Johannesson\, Tulane University\, kjohanne@tulane.eduJohan Schijf\, UMCES/Chesapeake Biological Laboratory\, schijf@cbl.umces.edu \n GEOTRACES Early Career Event: \nArctic-GEOTRACES Early Career Researcher Networking Event (ASLO 2017)26 February 2017 – 13h – Room: 305 A/B \nOver the 2015 and 2016 field seasons\, the international GEOTRACES program undertook a coordinated effort to better understand the distribution\, biogeochemical cycling\, and climate sensitivity of trace elements and isotopes (TEIs) within the Arctic Ocean. Three successful cruises were carried out in 2015 by Canadian\, US\, and German programs\, with follow-up sampling in 2016 by the German team. This effort brought together cross-disciplinary researchers from more than 12 countries working not only in the field of trace metal geochemistry\, but also observationalists and modelers studying phytoplankton physiology\, air-sea gas fluxes\, carbon and nutrient cycling\, ocean mixing\, sea ice\, and rivers. As a result\, new data sets are emerging to expand our understanding of the TEIs that regulate\, or serve as tracers for\, critical biogeochemical and physical processes within the Arctic Ocean. \nMore than 75 Early Career Researchers (ECRs: students\, postdocs and early career scientists) participated in the three Arctic Ocean cruises carried out in 2015\, with many more on the sidelines processing samples\, interpreting observations\, and developing ocean models. The goal of this workshop will be to provide a networking event for Arctic GEOTRACES ECRs who will be attending the ASLO Aquatic Sciences meeting. This forum will provide a bridge to connect ECRs between programs and establish new connections for participants to carry forward into their future careers within the GEOTRACES community. \nIdeal audience: “Early Career” Arctic GEOTRACES program participants\, including graduate students\, postdocs\, and new faculty \nTo register: All participants should send an RSVP before 25th of January. The way to do this is by filling up the following link: https://docs.google.com/spreadsheets/d/1D5a0lNLItm5x9X0bQMniutFEyOclUkxpspqb7ERb-8I/edit?usp=sharing \nAgenda (~3 hr Workshop): \n30 min (7-8 min each cruise): Introduction to each of the US\, Canadian\, German cruises\, and the focus\, cruise track\, and participants of each cruise \n30 min: 30 second introductions from each attendee about their role in the program (1 slide). \n60 min: breakout groups organized by theme/measurement type (to be decided). \n          * Goals of breakout groups: determine areas for collaborations\, emerging research themes\, future studies \n30 min: breakout group recap\, future plans \n30 min: Networking\, drinks and snacks!
