attribute NC_GLOBAL acquisition_description String Water column sampling:  \n Radium and thorium isotopes were collected on manganese-coated cartridges\nfiltered at depth using an adapted McLane in situ pump (WTS-LV). The pumps\nwere programmed to filter 1500-2000L of seawater per deployment. Water (15-25\nL) was also collected at the same depth using a 30L Niskin bottle; these\nsamples were filtered (at <1L/min) through a manganese-coated acrylic fiber\nand used to calculate radium extraction efficiency of the pumped samples. The\ncartridges were rinsed with radium-free fresh water and excess moisture was\nremoved using compressed air. Samples were analyzed three times using a\ndelayed coincidence counter (RaDeCC) for 223Ra, 224Ra, 228Th, and 227Ac. The\ncartridge and fiber media were ashed at 820 degrees C and measured on gamma\ndetectors for long lived radium (226Ra, 228Ra) and thorium isotopes. 226Ra was\ndetermined via alpha scintillation counting of the Niskin bottle Mn fiber\nsamples.\n \nSurface water sampling:  \n Surface water radium samples (280 L) were collected from approximately 2 m\nusing a submersible surface pump and filtered through a manganese coated\nacrylic fiber, which quantitatively scavenges radium from the seawater. Fiber\nsamples were then ashed in a muffle furnace at 820 degrees C for 24 hours and\nthe fiber ash was transferred to polystyrene vials, sealed with epoxy (to\nprevent 222Rn loss), and counted on high purity, well-type germanium detectors\nto measure 228Ra, using the lines of 228Ac (338 KeV and 911 KeV), and 226Ra,\nusing the line for 214Pb (352 KeV). Detector efficiencies were determined by\nmeasuring ashed fiber standards prepared with a standard solution containing\n226Ra and 232Th with daughters in equilibrium.

The WTS-LV systems are large volume in-situ filtration systems designed to collect sinking particulates. WTS-LV systems are individual in situ, battery-powered, pumping/filtration units that can be deployed at multiple depths per cast to provide information on how particle flux changes with depth. The McLane WTS-LV series of oceanographic pumps draw ambient water through filters and can pump large volumes of seawater during a single cast. The WTS-LV pumps are designed for use from a hydro-wire and employ advanced control algorithms to dynamically optimize flow rates as material accumulates on a filter.

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, investigators participating in the 2015 U.S. GEOTRACES Arctic expedition will measure radium and thorium isotopes in the western Arctic Ocean. In common with other national 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. The radionuclides to be measured as part of this project are important because they are oceanographic tracers that provide information on rates of cycling of other trace elements. The project will involve training opportunities for graduate student researchers and for undergraduate students from under-represented groups. Results from the study will be shared publicly through the Woods Hole Oceanographic Institution's Center for Marine and Environmental Radioactivity.\nWhile other GEOTRACES projects will map the distribution of numerous trace elements and their isotopes (TEIs), their distribution cannot be properly interpreted without concurrent measurement of tracers capable of providing rates of internal TEI cycling processes and fluxes at boundaries and across interfaces. The isotopes to be measured in this project include a suite of uranium/thorium series radionuclides, including the shorter-lived 234-Th and 228-Th as well as the radium quartet (224-Ra, 223-Ra, 228-Ra, 226-Ra). These tracers have the appropriate half-lives and reactivities to allow for study of horizontal and vertical transport and mixing, as well as removal at ocean boundaries, supply via rivers and submarine groundwater discharge, surface scavenging and export and subsurface remineralization. The researchers have considerable experience developing and implementing the most efficient methods to sample and quantify this suite of tracers, which includes use of battery powered in-situ pumps for large volume sampling. Hence, in addition to the proposed work on uranium/thorium series radionuclides, the team will also provide a service to other GEOTRACES researchers by coordinating pump use and sampling for many essential particulate TEIs.
