attribute NC_GLOBAL acquisition_description String Whole seawater samples for obtaining the concentration of total organic sulfur\n(TOS) were collected directly from the Niskin bottles into combusted 40 mL\nglass vials. The vials were stored frozen (-20\\u00b0C) until analysis on land.\n \nTOS was determined as described in Cutter et al. In brief, a sample is pumped\nthrough three ion exchange cartridges connected in series, a 1 mL Ba (Dionex\nOnGuard II #057093) to remove most of the sulfate, then through a 2.5 mL Ag\n(Dionex OnGuard II Ag #057090) to remove chloride, and finally through a 1 mL\ncartridge packed with BioRad AG 4x4 resin (#143-3341) to remove the remaining\nsulfate. The resulting sample is then analyzed via ion chromatography to\nquantify remaining sulfate. Total sulfur is quantitatively converted to H2S by\nvia reductive pyrolysis in pure hydrogen gas and quantified by gas\nchromatography/flame photometric detection using the trapping /detection\nsystem of Radford-Knoery and Cutter. Total organic sulfur is calculated as the\ndifference between total sulfur and residual sulfate. Each step of this\nanalysis has an error attached. The units for TOS are nM; when\nprovided,\\u00a0TOS_sd is the standard deviation of the average for replicate\nsamples. Precision was >10% RSD at/above 200 nM S and the detection limit was\n26 nM S.

attribute NC_GLOBAL instruments_0_description String A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends.  The bottles can be attached individually on a hydrowire or deployed in 12, 24 or 36 bottle Rosette systems mounted on a frame and combined with a CTD.  Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc.

attribute NC_GLOBAL instruments_1_description String Ion chromatography is a form of liquid chromatography that measures concentrations of ionic species by separating them based on their interaction with a resin. Ionic species separate differently depending on species type and size. Ion chromatographs are able to measure concentrations of major anions, such as fluoride, chloride, nitrate, nitrite, and sulfate, as well as major cations such as lithium, sodium, ammonium, potassium, calcium, and magnesium in the parts-per-billion (ppb) range.

attribute NC_GLOBAL project String Deep Atlantic DOM
attribute NC_GLOBAL projects_0_acronym String Deep Atlantic DOM
attribute NC_GLOBAL projects_0_description String Transformations of dissolved organic matter (DOM) in the deep ocean have profound impacts on the global carbon cycle due to the sequestration of carbon dioxide (CO2) away from the atmosphere.  Although research has been conducted on the high molecular weight component of this material, the same cannot be said for low molecular weight DOM because the needed analytical techniques have not been available to determine its composition and reactivity.\nIn recent years, a research team at Woods Hole Oceanographic Institution has acquired the necessary analytical capability. As such, in this project, they will carry out the first systematic survey of deep ocean DOM in the western Atlantic Ocean to characterize the low molecular weight fraction of DOM in southward flowing North Atlantic Deep Water (NADW), northward flowing Antarctic Bottom Water (AABW), and Antarctic Intermediate Water (AAIW).  Using ultrahigh resolution mass spectrometry and multi-stage fragmentation coupled to liquid chromatography, the scientists will determine the spatial variability in the composition of DOM along the flow path of the water masses, as well as assess the source water, transport, and surface processes that contribute to temporal changes in DOM composition.  These results will be augmented with structural elucidation and quantitative assays of unique marker compounds for each water mass.  Results will provide important insights into the biogeochemical reactions that govern DOM dynamics in the deep ocean.
