attribute NC_GLOBAL acquisition_description String Samples for inorganic nutrient analysis were collected in HDPE bottles and\nfrozen (-20\\u00baC) immediately after sample collection. Samples were kept\nfrozen until processing by Joe Jennings at Oregon State University. The\nanalyses for phosphate (PO4), nitrate plus nitrite (NO3_NO2), nitrite (NO2),\nammonium (NH4), and silicic acid (silicate) were performed using a hybrid\nTechnicon AutoAnalyzerII and Alpkem RFA300 system following protocols modified\nfrom Gordon et al. (see below for reference). The estimated precision for each\nelement was as follows: PO4, \\u00b1 0.008 \\u00b5M; NO3_NO2, \\u00b1 0.15\n\\u00b5M; NO2, \\u00b1 0.01 \\u00b5M; silicic acid, \\u00b1 0.3 \\u00b5M.\n \nTo obtain the concentration of total organic carbon (TOC) and total nitrogen\n(TN), a 40 ml aliquot of whole seawater was acidified to pH~3 with\nconcentrated hydrochloric acid (HCl) and stored in combusted glass vials at\n4\\u00b0C until analysis with a Shimadzu TOC-VCSH total organic carbon analyzer\ncoupled to a TNM-1 analyzer. Blanks (MilliQ water) and standard curves with\npotassium hydrogen phthalate and potassium nitrate were interspersed into the\nsample runs. The coefficient of variability between replicate injections was\n<1%. Comparisons to standards provided by Prof. D. Hansell (University of\nMiami) were made daily.\n \nReferences:  \n Gordon, L.

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.
