SUMMARY:2012 Ocean Sciences Meeting
DESCRIPTION:2012 Ocean Sciences Meeting20–24 February 2012Location: Salt Lake City – Utah – USA \nFor further information: http://www.sgmeet.com/osm2012/ \nRelevant sessions:  \n*057: Biogeochemical Cycling of Micronutrient Trace Elements  Organizers: Maeve Lohan\, University of Plymouth; Andrew Bowie\, Antarctic Climate & Ecosystems CRC; Toshi Gamo\, Univeristy of Toyko; Greg Cutter\, Old Dominion University  There is growing international interest (e.g.\, GEOTRACES\, SOLAS\, IMBER) to identify processes and quantify fluxes that control the distributions of key trace elements and isotopes in the ocean and to establish the sensitivity of these distributions to changing environmental conditions. This session will focus on the trace elements that serve as micronutrients (e.g.\, Fe\, Cu\, Co\, Zn\, etc)\, the availability of which influence the biogeochemical activity of marine organisms\, control the structure of ocean ecosystems and hence regulate the ocean carbon cycle. We also welcome presentation of data on diagnostic trace elements (e.g.\, Al\, Mn\, rare earths\, etc) and isotopes that help characterise micronutrient sources and sinks. Submissions are invited which focus on micronutrients and diagnostic tracers in different phases (dissolved\, particulate\, speciation) that have been studied both along ocean sections from different ocean basins and in the context of process studies. We also welcome abstracts focusing on the numerical modeling of micronutrients to quantify lateral and vertical transports\, as well as biogeochemical sources and sinks. \nView the complete abstracts of the oral and poster presentations. \n *049: Advances in the Oceanography of Trace Elements and Isotopes in the Atlantic and Polar Oceans  \nOrganizers: Micha Rijkenberg\, Royal Netherlands Institute for Sea Research; Rob Middag\, University of California Santa Cruz; Stephanie Owens\, Woods Hole Oceanographic Institution; Patricia Cámara Mor\, Universidad Autonoma de Barcelona \nThe dynamic hydrography of Atlantic\, Arctic and Antarctic Oceans is key to the distribution of trace elements in the global oceans. Trace elements like iron play a pivotal role in controlling ocean productivity and therefore global climate. Moreover\, several Trace Elements and Isotopes (TEIs; stable or radioactive; natural or anthropogenic) serve as important tracers for unraveling ocean processes and turnover rates. Novel ultraclean rapid sampling systems and international reference samples facilitate measurement of TEIs along deep ocean sections in unprecedented high spatial resolution\, coverage and accuracy. For example\, the international effort resulted in the thus far longest 13000 kilometer full depth ocean section of TEIs in the Atlantic basin. Intercalibration at crossover stations further confirms accuracy between cruises. The high resolution and multi-tracer approaches produces novel relationships among TEIs and other tracers\, and reveals details not seen before. This in turn leads to shifts of paradigms. For example\, hydrothermal supply of iron and manganese appears more important for ocean inventory budgets than previously realized. For this session we like to invite topics on TEIs in the Atlantic and polar oceans\, including methods\, intercalibration\, field data and ocean modeling. Relevant topics in other oceans are most welcome as well. \nView the abstracts of the oral and poster presentations. \n*005: Metal Speciation in the Ocean: Metal-Binding ligand composition and role in the transport of metals through the marine environment  \nOrganizers: Sylvia Sander\, University of Otago; Constant van den Berg\, University of Liverpool; Kristen Buck\, Bermuda Institute of Ocean Sciences \nThe biogenic trace metals iron\, cobalt\, zinc\, nickel and copper are complexed by organic ligands in the marine system\, which can influence trace metal solubility and bioavailability. Little is known about the composition of these metal-binding ligands\, although siderophores\, thiols\, humic substances and saccharides have been identified. There is evidence that this organic complexation helps transport trace metals from their source (hydrothermal vents\, estuaries\, etc.) to the open ocean. Dynamic aspects related to photochemical changes in metal speciation are also being recognised. This session welcomes abstract submissions related to all aspects of metal speciation in the oceans\, and particularly to identifying sources and cycling processes of metal-binding ligands.  \nView the complete abstract of the oral and poster presentations.  \n*166: Redox and Coordination Chemistry of Iron Marine Systems \nOrganizers: James Moffett\, University of Southern California; Katherine Barbeau\, UC San Diego \nIron undergoes redox cycling between Fe(II) and Fe(III)\, and is strongly complexed by organic ligands. In the upper ocean\, organically complexed forms predominate and ultimately determine the reactivity and biological availability of iron. Fe(II) is produced through biological and photochemical processes and may at times be the predominant inorganic form of iron\, even in oxygenated waters. Recent evidence suggests that the coordination environment of iron created through organic complexation may influence the kinetics and thermodynamics of redox cycling. This session is directed at investigators who are studying iron redox and complexation processes at the molecular level\, and how those processes interactively influence biological iron utilization and cycling in diverse marine environments. Both field and laboratory-based investigations are of interest. While the session is focused on iron\, studies of related processes with other transition metals are also welcome. \nView the complete abstract of the oral and poster presentations. \n*EVW09: US Arctic GEOTRACES (Town Hall)Wednesday February 22\, 18:00 – 21:00\, Room 151 A\, B\, C\, G \nOrganizers: David Kadko\, University of Miami; Robert Anderson\, Lamont-Doherty Earth Observatory. \nGEOTRACES is an international program focused on understanding the cycling of trace elements and isotopes in the oceans. Since the inception of this program\, there has been strong interest in carrying out studies in the Arctic Ocean. The Arctic Ocean is at the epicenter of climate change\, and warming climate will likely have a profound impact on the carbon budget\, geochemical cycles\, and ecosystem of the Arctic. Furthermore\, these changes will ultimately be felt globally\, through feedbacks related\, for example\, to melting ice and release of carbon from permafrost. This interest has led to national and international discussions\, and planning has begun for a multi-national\, multi-icebreaker\, GEOTRACES field effort to the Arctic likely in 2015. The US will be an active participant in this endeavor. The purpose of this meeting is to provide an update on the status of the planning process and to solicit input from the community. \n*EVT15: ConCOAC: Connecting Chemical Oceanography with Analytical Chemistry (Town Hall)Tuesday February 21\, 18:00 – 21:00\, Ballroom J \nOrganizers: Chris Measures\, University of Hawaii; Maxime Grand\, University of Hawaii. \nWe are developing a new program to connect experts from analytical chemistry with oceanographers to adapt newly available technology to the determination of parameters in seawater that are of interest to oceanography. The goal of the town hall is to alert the broader community to our open science meeting\, the first component of this new program. We seek community input into workshop design particularly from young scientists who will become active members of this bridge between the fields.

SUMMARY:AAAS 2012 Annual Meeting
DESCRIPTION:American Association for the Advancement of Science (AAAS) 2012 Annual MeetingDates: 16-20 February 2012Location: Vancouver\, Canada \nFor more information:  http://www.aaas.org/meetings/ \nRelevant sessions: \n*Documenting a Changing Ocean Through International Multidisciplinary CollaborationsFriday\, February 17\, 2012: 1:30 PM-4:30 PMRoom 212 (VCC West Building) \nResource exploitation\, pollution\, acidification\, temperature\, and salinity changes are altering marine ecosystems\, seawater chemistry\, and ocean circulation in complex ways that are interconnected and feedback on the causes that initiated them. Understanding these changes is essential to providing food sources\, to sustaining economic development\, and to predicting future atmospheric greenhouse gas levels and global warming. The complexities and interrelatedness of these questions demand that oceanographic research be multidisciplinary\, integrative\, and based on global-scale observations conducted through large\, frequently multinational\, programs. The speakers will present major achievements from large-scale oceanographic programs addressing interrelated physical\, chemical\, and biological changes in the ocean. They will particularly focus on lessons learned and future challenges in crafting cross-cutting\, collaborative\, and global ocean observational programs. \nOrganizer: Roger Francois\, University of British ColumbiaCo-organizers: Roberta Hamme\, University of Victoria and Andrey Proshutinsky\, Woods Hole Oceanographic Institution \nSpeakers: \nEddy Carmack\, Fisheries and Ocean CanadaRapidly Changing Arctic Ocean: Observations from the International Polar Year \nHein de Baar\, Royal Netherlands Institute for Sea ResearchHighlights of Recent GEOTRACES Field Programs \nIan Perry\, Fisheries and Oceans CanadaShifting Paradigms and Improving Decision-Making for Marine Systems Under Change \nW.

SUMMARY:Asia-Oceania Geosciences Society (AOGS) Meeting 2011
DESCRIPTION:Asia-Oceania Geosciences Society (AOGS) Meeting 2011Dates: 8-12 August 2011Location: Taipei – Taiwan \nFor more information: http://www.asiaoceania.org/aogs2011/ \nAbstract submission is closed. \nRelevant Sessions: \nSession 1 details (OS09) Section OS – Ocean Sciences Session Title: Geochemical and Isotopic Proxies Deciphering Past Environmental and Oceanographic Changes \nMain Convener(s): Dr. Selvaraj Kandasamy (Academia Sinica\, Taiwan). \nCo-convener(s): Dr. Nagender Nath Bejugam (National Institute of Oceanography\, India). Dr. Madhavaraju Jayagopal (Universidad Nacional Autonoma de Mexico\, Mexico). Dr. Shuh-Ji Kao (Academia Sinica\, Taiwan ). \nSession Description \nEarth System Scientists and Marine Geochemists are interested in reconstructing the past environmental and oceanographic changes over the orbital to millennial timescales by using solid-phase geochemical proxies. Geochemical proxy data for paleoenvironmental and paleoceanographic changes could have large uncertainties\, and thus this decade has witnessed the invention of several new proxies\, catalyzing a renaissance of sediment geochemical research especially from South and East Asian regions. This session focuses on the advances made in using elemental and isotopic proxies for the past environmental and oceanographic changes in the low- and mid-latitude regions. We welcome contributions related to the critical evaluation of climate-environmental-specific proxies in modern and ancient terrestrial\, lacustrine and oceanic environmental settings. \n  \nSession 2 DetailsSectionIWG – Interdisciplinary Working Groups Session Title: Weathering Studies in Asia: Geochemical and Clay Mineralogical Constraints from Modern and Ancient Sediments  \nMain Convener(s): Dr. Nagender Nath Bejugam (National Institute of Oceanography\, India). \nCo-convener(s): Dr. Selvaraj Kandasamy (Academia Sinica\, Taiwan). Dr. Madhavaraju Jayagopal (Universidad Nacional Autonoma de Mexico\, Mexico). \nSession Description \nThe Earth’s Critical Zone and associated terrestrial life is governing by two interdependent surface processes\, namely erosion and weathering. A combination of atmospheric carbon dioxide levels and continental weathering intensity controls the Earth’s climate on glacial-interglacial timescales. Recent chemical weathering investigations from East Asia \, although only a few\, reveal a wide range of chemical weathering conditions that were not previously known. Given the importance of diverse climatic and tectonic regimes in Asia \, this session explores the recent advances in chemical weathering using geochemical and clay mineralogical studies of river\, lake and ocean sediments\, including sedimentary rocks. Chemical weathering studies from oceanic islands\, in-land lake systems and comparison between large and small river systems in Asia are most welcome. This session further evaluates the unexplored potential geographical regions for future investigations.

SUMMARY:ASLO 2011\, Aquatic Sciences Meeting
DESCRIPTION:ASLO 2011\, Aquatic Sciences MeetingDates: 13-18 February 2011Location: Puerto Rico \nFor more information: http://www.aslo.org/meetings/sanjuan2011/ \n\nRelevant Sessions:  \n*GSO2: Chemical Oceanography/GEOTRACESPresentations available at: https://www.sgmeet.com/aslo/sanjuan2011/sessionschedule.asp?SessionID=GS02 \nConveners: Greg Cutter\, Old Dominion University and Pere Masqué\, Universitat Autònoma de Barcelona \n*S87: Trace Metals and their Nutritional Importance to Marine Phytoplankton and BacteriaPresentations available at: http://www.sgmeet.com/aslo/sanjuan2011/sessionschedule.asp?SessionID=S87 \nConveners: Mak Saito\, Woods Hole Oceanographic Institution; Pete Sedwick\, Old Dominion University. \nThe past few decades have seen a growing appreciation of the vital role of micronutrient trace metals in the ocean carbon cycle. With the launch of the international GEOTRACES program and the rapid development of molecular techniques\, now is an opportune time to strengthen linkages between the geochemists and biologists who focus on trace metals and metalloproteins in the ocean. For this session\, we invite presentations on geochemical\, physiological\, biochemical and modeling studies that address the complex interactions between trace micronutrients and marine microbiota on scales ranging from global to molecular. \n*Town Hall Meeting: Microbial Biogeography and Biogeochemistry   \nConveners:  Eric Webb\, University of Southern California and Ben Van Mooy\, Woods Hole Oceanographic Institution. \n An Ocean Carbon and Biogeochemistry (OCB) Scoping Workshop chaired by Jim Moffett and Eric Webb (University of Southern California) was held in Los Angeles in November 2010 entitled “The Molecular Biology of Biogeochemistry.” The goal of this workshop was to assess the potential role of molecular biology to study marine biogeochemical cycles\, particularly the carbon cycle\, via large survey programs such as GEOTRACES.  Rapid advances in molecular methods are providing new tools applicable to global surveys and other observational programs focused on the oceans’ response to changing climate and other impacts.   However\, molecular biologists generally examine ecological problems like community diversity\, whereas geochemists are more interested in functionality and rates.  Here\, geochemists and molecular biologists sought common ground to identify which molecular biological measurements would be most useful for understanding marine biogeochemical cycles and characterizing their response to climate change. \n Workshop participants were enthusiastic about the integration of geochemical and marine biological tools in existing large survey programs but recognized the need for a new\, stand-alone field campaign to characterize the biogeography of marine microbial communities that will complement the existing global survey and observational programs.  The new program will characterize the distribution of microbial communities within the ocean on complete surface to bottom sections and couple these data with important geochemical measurements and rate measurements of key processes.    Such a program was seen as essential to achieve the core science objectives in biogeochemistry that was the charge of the workshop.  A stand-alone program is desirable for logistical and science reasons\, but the core parameters in GEOTRACES are highly complementary.  Therefore\, a plan was outlined for a sectional survey cruise in Fall 2013 concurrently or back to back with a proposed GEOTRACES zonal section in the eastern tropical South Pacific.  The effort will be spearheaded by participants at the workshop\, and led by Ginger Armbrust (University of Washington).  However\, planning of the program is still at a very early stage\, and input from the broader community of marine microbiologists\, biogeochemists and modelers is essential.  \n The following objectives were developed as an organizational framework for the development of the hypotheses and approaches for the first sectional cruise and the program as a whole: \n (1)    Characterize and define the connections between the presence and activity of microbes (i.e.\, functional biogeography) and physical and chemical parameters\, utilizing the tools of an unprecedented\, large group of microbiologists and geochemists. (2)    Utilize genomics\, transcriptomics\, proteomics\, and metabolomics in combination with process measurements to define biogeochemical ‘connections’ and their constraints. (3)    Integrate results from multiple sections to identify boundaries of microbial biogeographic provinces (analogous to the Longhurst provinces) over horizontal and vertical scales.\n(4)    Develop an operational framework for many laboratories to collaborate together using a variety of molecular and biogeochemical  tools that includes rigorous protocols for methodological inter-calibration and standardization (5)    Incorporate the program’s observations into a new generation of models that capture the connections between microbes and chemistry in an ocean perturbed by climate change.  \n At the Town Hall Meeting\, these plans will be discussed along with a detailed summary of the meeting deliberations about the topics in points 1-5.

SUMMARY:2010 Ocean Science Meeting
DESCRIPTION:2010 Ocean Sciences MeetingDates: 22 – 26 FebruaryLocation: Portland\, Oregon \nFor further information: http://www.agu.org/meetings/os10/ \nRelevant sessions: \n*C007: GEOTRACES in the International Polar Year \nConvener: Rob Middag\, Royal Netherlands Institute for Sea Research; Delphine Lannuzel\, University of Tasmania and Celia Venchiarutti\, Alfred Wegener Institute. \nTrace elements\, such as iron\, play a pivotal role in controlling ocean productivity and therefore global climate. Moreover several trace elements and isotopes serve as key tracers for unraveling processes and turnover rates in the oceans. The international GEOTRACES program pursues the characterization of marine biogeochemical cycles of Trace Elements and Isotopes (TEIs; stable or radioactive; natural or anthropogenic). In context of the International Polar Years (IPY) 2007-2009 the GEOTRACES program had its flying start with four Arctic and six Antarctic expeditions in order to study TEIs abundances\, processes and fluxes in the polar oceans. The multi-tracer approaches and inter-calibration exercises carried out during IPY-GEOTRACES have produced novel relationships among TEIs and other tracers and improved methods for sampling and analyses. We seek topics on TEIs as controling elements as well as tracers of biogeochemical processes in the polar oceans in the context of IPY-GEOTRACES and other relevant projects. \n*C009: Getting the Right Number: Precision and Accuracy in Chemical Oceanography \nConvener: Gregory Cutter\, Old Dominion University and Robert Sherrell\, Rutgers University. \nAccuracy and precision are essential for all biogeochemical studies. Some important chemical species are in extremely low concentration while others require high precision for optimal interpretation. Intercalibration is an active process among laboratories that includes all steps from sampling to analyses\, with the goal of achieving the same accurate results regardless of the method or lab. Past intercalibration efforts included examinations of colloids and carbonate system parameters\, and more recently the Sampling and Analysis of Iron (SAFe) experiment. The GEOTRACES intercalibration program is currently underway. This session seeks presentations focusing on methods to assess the accuracy and precision of determining various chemical parameters in the ocean (from organics to metals to isotopes in dissolved and particulate phases) and results from intercalibration programs. An important goal will be for attendees to discuss how best to assess accuracy from sampling to analysis when suitable certified reference materials are not available. \n
