attribute NC_GLOBAL acquisition_description String Samples collected from Niskin bottles using the GEOTRACES ODF CTD-rosette\nsystem. (Note on niskin trip depths reported in dataset: multiple bottles were\ntripped to collect sample water; these samples were linked to the Niskin\nnumber having both oxygen and salinity bottle data.)\n \nSeawater samples for \\u03b430Si measurements were collected using a\nOceanographic Data Facilitiy\\u2019s (ODF, Scripps Institution of Oceanography)\nCTD-rosette mounted with Niskin samplers and a Sea-Bird Electronics CTD\n(SBE9plus). Seawater was gravity filtered into polypropylene containers\nthrough in-line Supor filter capsules (0.8/0.45 \\u00b5m) attached directly to\neach Niskin bottle. Sample bottles were capped and stored without preservative\nin the dark.\n \nBack in the laboratory, the silicon from seawater was precipitated of as\ntrimethylamine silicomolybdate using a high purity triethlyamine ammonium\nmolybdate solution (TEA-Moly). The precipitate was isolated by filtration onto\na polycarbonate filter and purified by high temperature combustion to produce\nsolid silicon dioxide. SiO2 was then converted to solid Cs2SiF6 by dissolution\nin HF and addition of CsCl. The Cs2SiF6 was rinsed with ethanol, dried and\ndissolved in high purity (>18M\\u03a9) water. BaSiF6 was precipitated by the\naddition of BaCl, rinsed with ethanol and dried.\n \nIsotopic ratio analysis was performed using a Nu Perspective isotope ratio\nmass spectrometer equipped with a Nu Sil inlet system. Samples as BaSiF6 are\nloaded into sample vials that are placed in a sample carousel in the Nu Sil.\nSamples are sequentially heated to 590\\u00b0C.\n \nIsotope delta values are normalized against the international standard NBS28.\n \nFor more information, see the Protocol document\\u00a0(under Supplemental\nFiles).

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:\nAn investigator will participate in the 2015 U.S. GEOTRACES Arctic Ocean expedition and measure silicon isotopes composition of silicic acid in seawater samples, as well as diatoms and sea ice. In common with 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. Some trace elements are essential to life, others are known biological toxins, and still others are important because they can be used as tracers of a variety of physical, chemical, and biological processes in the sea. As silicon is a key component of diatom shells, the measurement of their concentrations in this study can provide an important indicator of primary productivity, both in the present day, as well as past oceans. The project will provide training for undergraduate students and a post-doctoral researcher in silicon chemistry, as well as include outreach to K-12 students.\nThe silicon isotope proxy is increasingly being used to assess the role of diatoms and silicic acid supply to past shifts in ocean productivity and their role in Earth's climate. Application of the proxy requires knowledge of the silicon isotopic composition of ventilating water masses. Uncertainty in these values translates directly into uncertainty in the level of productivity implied by the proxy. The growing global data set of silicon isotopes in marine waters suggest that silicon isotopes in subsurface waters are not uniform, but vary systematically driven by interactions between silicon isotope fractionation, the biological pump and thermohaline circulation. In addition, significant anomalies exist between model predictions and observations. In this study, researchers will test hypotheses regarding the origin of this signal and the mechanisms controlling silicon isotope distributions within the Arctic Ocean by greatly expanding the silicon isotope data set for this region. The overarching hypothesis to be tested is that silicon isotope distributions are controlled by the coupling of silicon fractionation during silica production and during silica dissolution to the biological pump and to the meridional overturning circulation.

attribute NC_GLOBAL summary String The isotopic composition of dissolved silicon (\\u03b430Si) has proven to be a powerful tool to better understand the marine Si cycle. The \\u03b430Si of seawater carries information about DSi utilization in surface waters, the subsequent dissolution of sinking biogenic material as well as water mass mixing. This data set supplies information on the spatial distribution of isotopes of Si within water masses in the Arctic Ocean from the Bering Strait to the north pole. Profiles of silicon isotopes within silicic acid, \\u03b430Si(OH)4, were obtained at a total of 15 stations on the GEOTRACES GN01 cruise
