attribute NC_GLOBAL acquisition_description String Samples were collected using the ODU GEOTRACES Carousel (GT-C), filtered\nthrough 0.2 um Acropak filters in the GEOTRACES clean van and immediately\nrefrigerated. Acid-washed 60 mL LDPE bottles were filled entirely, leaving no\nheadspace. Total dissolved cobalt samples were kept at ambient pH, preserved\nin a heat-sealed bag containing gas absorbing satchels immediately after\nsample collection and kept at 4 degrees C until analysis upon return to the\nWoods Hole laboratory. Labile cobalt were kept at ambient pH, and sampled in\nseparate bottles stored in plastic bags without gas absorbing satchels at 4\ndegrees C.\n \nThe carousel was used to collect samples from surface to near bottom waters.\nAdditional samples were collected from a surface pump when sea ice conditions\npermitted. Pre-conditioned, teflon-coated 12L Go-Flo sampling bottles (General\nOceanics, Miami, FL) were deployed on a polyurethane powder-coated aluminum\nrosette with titanium pilings and pressure housings (Sea-Bird Electronics,\nInc., Bellevue, WA) attached to a Kevlar, non-metallic conducting cable. For\nmore information regarding carousel deployment, please refer to the GEOTRACES\nCookbook, cited below and located on the GEOTRACES Program website\n([https://www.geotraces.org/](\\\\\"https://www.geotraces.org/\\\\\")). Following\ncarousel retrieval, Go-Flo bottles were moved to the GEOTRACES Program\nclass-100 trace metal clean van, and pressurized with HEPA filtered air for\nsampling in accordance with published methods (Cutter and Bruland 2012).\nSurface pump samples were collected by zodiac, and a trace metal clean\nperistaltic pump following the GEOTRACES Program Cookbook sampling\nrecommendations, and in accordance with previous collection protocols (Bruland\net al. 2005).\n \nSample storage and reagent bottles were soaked for >1 week in the acidic\ndetergent Citranox, rinsed thoroughly with 18.2 M-Ohm Milli-Q water\n(Millipore), filled with 10% HCl to soak for 10 days, and rinsed thoroughly\nwith Milli-Q water adjusted to pH 2 with TM-grade HCl. Reagent purification\nprotocols were identical to those previously published (Saito and Moffett\n2001).\n \nConcentrations of total dissolved cobalt and labile cobalt were determined\nusing a previously described cathodic stripping voltammetry (CSV) method\n(Saito and Moffett 2001, Saito et al. 2004). Measurements were made using the\nEco-Chemie \\u00b5AutolabIII systems connected to Metrohm 663 VA Stands\nequipped with hanging mercury drop electrodes and Teflon sampling cups. Sample\npreparation was modified slightly to accommodate use of a Metrohm 837 Sample\nprocessor, operated with NOVA 1.8 software (Metrohm Autolab B.V.).\n \nFor total dissolved cobalt analyses, samples were UV-irradiated for 1 h prior\nto analysis in a Metrohm 909 UV digester to degrade the organic ligands that\nbind cobalt, enabling full chelation by the added electroactive ligand,\ndimethylglyoxime (DMG). 11 ml of sample was pipetted into 15ml polypropylene\ntubes. Recrystallized DMG (0.1M in methanol) was added to a final\nconcentration of 400 uM and purified\nN-(2-hydroxyethyl)piperazine-N-(3-propanesulfonic acid) (EPPS) buffer (0.5 M\nin Milli-Q water) was added to a final concentration of 3.8 mM. Tubes were\ninverted several times before being placed in the autosampler queue, where 8.5\nml of the mixture was dosed into the teflon analysis cup using a 800 Dosino\nautomated burrette (Metrohm). 1.5 ml of purified sodium nitrite (1.5M in\nMilli-Q water) was added directly to the Teflon cup using a dedicated 800\nDosino burrette. Once loaded, samples were purged with high purity (>99.99%)\nN2 for 3 min and cobalt concentrations were determined by standard addition,\nwith triplicate measurement of the sample followed by four 25 pM cobalt\nadditions. 5 nM Co stock was diluted from a certified 1ppm reference (SPEX)\nand added to the analysis cup via a third Dosino burrette.\n \nFor labile cobalt analyses, 11 ml of sample were pipetted into acid washed\nteflon vials, preconditioned with a small aliquot of sample water. DMG was\nadded to a concentration of 400 uM and allowed to equilibrate for 8-16hr in\nthe dark prior to analysis (Saito et al. 2004). EPPS was added just prior to\nmeasurement using the same standard addition protocol described above.\nPreviously, we determined that natural cobalt ligands in seawater have a\nconditional stability constant of >10^16.8 (Saito et al. 2005). This suggests\nthat the cobalt is very strongly bound to ligands. Thus, we define labile\ncobalt as the fraction of total dissolved cobalt that is either bound to weak\norganic and inorganic ligands in seawater or present as free Co(II), and is\nthen exchangeable with the complexing agent (DMG) used for analysis (Saito et\nal. 2004, Saito et al. 2005). The difference between the total dissolved\ncobalt and the labile cobalt can then be used as an estimation of the strong\ncobalt ligand concentration. The same electrode was used for both total and\nlabile analyses. Before transitioning from labile analyses to total analyses,\nthe autosampler tubing and Teflon cup were rinsed with Milli-Q water and pH2\nHCl in Milli-Q water.\n \nThe analytical blank was determined by analyzing seawater that had been UV-\nirradiated for 1 h, equilibrated overnight with prepared Chelex 100 resin\nbeads (Bio-Rad), and UV-irradiated a second time to degrade any leached\nsynthetic ligands. For in lab analyses, mean blank was 2.5 +/- 0.7 pM (n=19),\nand the detection limit was 2.2 pM.\n \nIntercalibration: GEOTRACES standard seawater and internal standard lab\nseawater were analyzed periodically. A large batch of UV oligotrophic seawater\nwas generated prior to sample analyses and used as a primary standard during\nmeasurements. This standard seawater was run along with each sample batch, as\nwere blanks, and values were consistent for the duration of analyses. Our\nlaboratory has participated in the GEOTRACES intercalibration effort using\nthis electrochemical Co method. Acidified standards were neutralized with\nconcentrated ammonium hydroxide (Seastar), mixing the entire sample between\ndrops, prior to UV digestion. We report our laboratory values for the\nGEOTRACES and SAFe standard analyses using this electrochemical method to be:\nSAFe D1 = 47.9 +/- 2.1 (n=3), SAFe D2 = 45.2 +/- 2.1 (n=3), GEOTRACES GSP =\n2.4 +/- 1.8 (n=3), GEOTRACES GSC = 77.9 +/- 2.8 (n=3). These results are in\ngood agreement with those from the GEOTRACES intercalibration effort for Co\nand demonstrate that the methodologies employed to produce this dataset detect\nconcentrations within the standard deviation of current consensus values for\nUV irradiated samples, which can be found on the International GEOTRACES\nProgram website\n([https://www.geotraces.org/](\\\\\"https://www.geotraces.org/\\\\\")).

attribute NC_GLOBAL projects_0_description String Description from NSF award abstract:\nIn pursuit of its goal \"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\", in 2015 the International GEOTRACES Program will embark on several years of research in the Arctic Ocean. In a region where climate warming and general environmental change are occurring at amazing speed, research such as this is important for understanding the current state of Arctic Ocean geochemistry and for developing predictive capability as the regional ecosystem continues to warm and influence global oceanic and climatic conditions. The three investigators funded on this award, will manage a large team of U.S.scientists who will compete through the regular NSF proposal process to contribute their own unique expertise in marine trace metal, isotopic, and carbon cycle geochemistry to the U.S. effort. The three managers will be responsible for arranging and overseeing at-sea technical services such as hydrographic measurements, nutrient analyses, and around-the-clock management of on-deck sampling activites upon which all participants depend, and for organizing all pre- and post-cruise technical support and scientific meetings. The management team will also lead educational outreach activities for the general public in Nome and Barrow, Alaska, to explain the significance of the study to these communities and to learn from residents' insights on observed changes in the marine system. The project itself will provide for the support and training of a number of pre-doctoral students and post-doctoral researchers. Inasmuch as the Arctic Ocean is an epicenter of global climate change, findings of this study are expected to advance present capability to forecast changes in regional and globlal ecosystem and climate system functioning.\nAs the United States' contribution to the International GEOTRACES Arctic Ocean initiative, this project will be part of an ongoing multi-national effort to further scientific knowledge about trace elements and isotopes in the world ocean. This U.S. expedition will focus on the western Arctic Ocean in the boreal summer of 2015. The scientific team will consist of the management team funded through this award plus a team of scientists from U.S. academic institutions who will have successfully competed for and received NSF funds for specific science projects in time to participate in the final stages of cruise planning. The cruise track segments will include the Bering Strait, Chukchi shelf, and the deep Canada Basin. Several stations will be designated as so-called super stations for intense study of atmospheric aerosols, sea ice, and sediment chemistry as well as water-column processes. In total, the set of coordinated international expeditions will involve the deployment of ice-capable research ships from 6 nations (US, Canada, Germany, Sweden, UK, and Russia) across different parts of the Arctic Ocean, and application of state-of-the-art methods to unravel the complex dynamics of trace metals and isotopes that are important as oceanographic and biogeochemical tracers in the sea.

attribute NC_GLOBAL projects_1_description String NSF Award Abstract:\nIn this project, a group of investigators participating in the 2015 U.S.GEOTRACES Arctic expedition will study the chemistry and regional distribution of seven trace metals in the Arctic Ocean: iron, manganese, zinc, cadmium, copper, nickel, and cobalt. These so-called bioactive metals are of special scientific interest because of their role in multiple biogeochemical processes including biological production of the sea and the planetary cycling of carbon and nitrogen. Like other multinational initiatives in the International GEOTRACES Program, the goals of the U.S. Arctic expedition are 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 study in particular would contribute to our understanding of the sources and sinks of these seven bioactive metals as well as examine their interaction with biological processes. The project will focus on two major overarching research questions: (1) What are the sources and sinks for micronutrients and macronutrients in the Arctic? And (2) How does bioactive trace element nutrition influence productivity and species composition in the Arctic, and conversely, how do biological processes influence the cycling of these metals? In terms of broader impacts, the PIs on this project will be actively involved in educational outreach efforts, and the research team itself will include two postdoctoral researchers and a graduate student. The team leaders also plan to publish a children's ocean education book based on the expedition with the aim of generating next-generation excitement about modern ocean science\nWith regard to technical specifics, the research team will measure the dissolved seawater phases of the bioactive metals Fe, Mn, Zn, Cd, Cu, Ni, and Co, the dissolved stable metal isotopes 56Fe, 66Zn, and 114Cd, and the chemical speciation of Co. The recent development of methods for multi-element and multi-isotope analysis methods, in conjunction with the high-resolution sampling of the GEOTRACES program, make it possible to efficiently produce this dense dataset of metals and metal isotopes. This will be a team-based approach to achieve comprehensive duplication for analysis of the key parameters of dissolved metal concentrations. Each investigator will further conduct specialized additional measurements of metal isotopes and dissolved Co (which has unique analytical challenges) and Co speciation. Interpretation of these rich datasets would will be directed toward determination of sources and sinks as well as their ecological stoichiometry, in collaboration with other U.S.GEOTRACES participants measuring synergistic parameters. Together, this Arctic Ocean bioactive trace metal dataset is expected to provide an important contribution to the understanding of micronutrient roles in Arctic biogeochemical processes. These results should also be highly relevant to research studies of the ancient ocean, in which trace-metal analyses are commonly used to trace a wide variety of processes including paleo-ocean circulation and biological productivity. Finally, understanding the sources and sinks for elements in the modern ocean is key to predicting how the concentrations of bioactive elements might vary in a changing future climate.
