attribute NC_GLOBAL acquisition_description String NO3- + NO2- concentration and isotopic composition analysis\n \nThe NO3- + NO2- concentration of samples was determined using chemiluminescent\nanalysis (Braman & Hendrix, 1989) in a configuration with a detection limit of\n0.05 uM, and +/- 0.1 uM for 1 standard deviation (S.D.). The d15N of NO3- +\nNO2- was determined using the \\u201cdenitrifier\\u201d method (K. L. Casciotti,\nSigman, Hastings, Bohlke, & Hilkert, 2002; Sigman et al., 2001) with\nmodifications (McIlvin & Casciotti, 2011) on samples with NO3- + NO2-\nconcentration >0.3 uM (typically <0.2\\u2030 1 S.D.) (Supp. Table 1) (Knapp,\nCasciotti, Berelson, Prokopenko, & Capone, 2016).\n \nDON concentration and isotopic analysis\n \nThe DON concentration of samples was determined using persulfate oxidation to\nconvert DON to NO3- (Solorzano & Sharp, 1980), adapted according to (Knapp et\nal., 2005). The resulting NO3- concentration was then measured using\nchemiluminescence as described above. In cases where NO3- + NO2- (and/or\nammonium, NH4+) was above the detection limit, DON was determined by\nsubtracting the concentration of NO3- + NO2-+NH4+ from the concentration of\ntotal dissolved N (TDN). The average standard deviation for duplicate DON\nconcentration analyses of individual samples that have undetectable levels of\nNO3- in the sample was +/- 0.30 uM, and the propagated error for DON\nconcentration in the presence of detectable NO3- was +/- 0.32 uM.\n \nThe d15N of DON was determined according to (Knapp et al., 2005), where DON\nsamples were oxidized to NO3- by persulfate oxidation (as described above in\nsection 2.2), acidified to a pH range of 3 to 4, and measured as NO3- by the\ndenitrifier method. In samples with measurable NO3- + NO2-, the d15N of DON is\ncalculated by mass balance by subtracting the NO3- + NO2- concentration and\nd15N of NO3- + NO2- from the TDN concentration and TDN d15N measurements. In\nsurface samples with undetectable NO3- + NO2- concentration, the standard\ndeviation of duplicate analyses of DON d15N in a sample is +/- 0.3\\u2030. For\nsubsurface samples with NO3- + NO2- concentration approximately equal to the\nDON concentration, the propagated error for the calculation of DON d15N using\na Monte Carlo method (Press, Teukolsky, Vetterling, & Flannery, 1992), and\nassuming duplicate analysis of a single sample and the standard deviations for\nTN concentration, NO3- + NO2- concentration and d15N of NO3- + NO2- given\nabove, is +/- 0.6 0/00. The 15N of DON in samples with NO3- + NO2-\nconcentration exceeding DON concentration, and/or with NH4+ concentration >\n0.2 uM, was not determined (i.e., Stations 9, 10, 11, and 12 from the 2010\ncruise).\n \nSampling\n \nSamples were collected on the R/V Atlantis in January through February 2010,\nand the R/V Melville in March through April 2011 between 10 and 20 \\u00baS and\n80\\u00ba W and 100\\u00ba W (Fig. 1), with station locations and sample depths,\nsalinities, sigma theta values, chlorophyll a concentrations, nitrate+nitrite\nconcentration, NO3-+ NO2- d15N, DON concentrations, and DON d15N reported in\nSupplementary Information Table 1. Water column samples were collected by\nNiskin bottles deployed on a rosette equipped with conductivity-temperature-\ndepth (CTD) sensors. All samples were collected into acid-washed, sample-\nrinsed HDPE bottles, and samples from the upper 400 m passed a 0.2 um filter\nbefore collection, and were stored at -20\\u00ba C until analysis on land.

attribute NC_GLOBAL project String N2 fixation ETSP,Microbial Nitrification
attribute NC_GLOBAL projects_0_acronym String N2 fixation ETSP
attribute NC_GLOBAL projects_0_description String Description from NSF award abstract:\nSeveral independent lines of geochemical and remote sensing evidence suggest that dinitrogen (N2) fixation may be associated with surface waters downstream of major oxygen minimum zones (OMZs) and in particular in the Eastern Tropical South Pacific (ETSP). However, little direct evidence supports these inferences. Besides substantiating these indirect assessments, documenting significant N2 fixation in the ETSP would provide insight into two longstanding controversies: Is the marine N budget balanced, as implied by modeling and paleoceanographic data, and if so, how are the processes that add and remove N spatially, and thus temporally coupled?\nIn this project researchers at the University of Southern California and the University of Miami will test the hypothesis that fixation occurs in the ETSP at areal rates that equal or exceed those previously documented in more well-studied regions such as the oligotrophic waters of the sub/tropical North Atlantic. If scaled to the surface area of ETSP waters, this could add an additional 10-50 Tg N per year of inputs to the global marine N budget. They will undertake two cruises in the ETSP during early and late summer in two consecutive years to assess the quantitative significance of N2 fixation as a source of new N to surface waters using complementary biological and geochemical tools. N2 fixation rates will be evaluated on two temporal/spatial scales: daily/local (bottle 15N2 incubations and floating sediment traps); and seasonal/regional (d15N budget using moored sediment traps and water column TDN d15N). These estimates provide detailed observations of potential N2 fixation during station occupation in two summer seasons, when rates are expected to be greatest, as well as prolonged observation over lower expected N2 fixation periods. A combination of these different estimates will aim to determine if N2 fixation in this region can help balance the marine N budget. If all goes as planned, this study will determine the quantitative importance of N2 fixation in the ETSP, and whether these previously undocumented rates can help resolve the marine N budget. Implications include the ability of the marine N cycle to maintain homeostasis, and thus the global C cycle on glacial/interglacial time scales.

attribute NC_GLOBAL projects_1_acronym String Microbial Nitrification
attribute NC_GLOBAL projects_1_description String Description from NSF award abstract:\nClosing the marine budgets of nitrate and nitrous oxide are central goals for researchers interested in nutrient-driven changes in primary productivity and climate change. With the implementation of new methods for oxygen isotopic analysis of seawater nitrate, it will be possible to construct a budget for nitrate based on its oxygen isotopic distribution that is complementary to nitrogen isotope budgets. Before we can effectively use oxygen isotopes in nitrate to inform the current understanding of the marine nitrogen cycle, we must first understand how different processes that produce (nitrification) and consume (assimilation, denitrification) nitrate affect its oxygen isotopic signature.\nIn this study, researchers at the Woods Hole Oceanographic Institution will provide a quantitative assessment of the oxygen isotopic systematics of nitrification in the field and thus fill a key gap in our understanding of 18O variations in nitrate, nitrite, and nitrous oxide. The primary goal is to develop a quantitative prediction of the oxygen isotopic signatures of nitrite and nitrate produced during nitrification in the sea. The researchers hypothesize that oxygen isotopic fractionation during nitrification is the primary factor setting the 18O values of newly produced nitrate and nitrite. Secondly, they hypothesize that oxygen atom exchange is low where ammonia oxidation and nitrite oxidation are tightly coupled, but may increase in regions with nitrite accumulation, such as in the primary and secondary nitrite maxima. They will test these hypotheses with a series of targeted laboratory and field experiments, as well as with measurements of nitrite and nitrate isotopic distributions extending through the euphotic zone, primary nitrite maximum, and secondary nitrite maximum of the Eastern Tropical South Pacific. The results of these experiments are expected to provide fundamental information required for the interpretation of 18O isotopic signatures in nitrite, nitrate, and N2O in the context of underlying microbial processes. A better understanding of these features and the processes involved is important for quantifying new production, controls on the N budget, and N2O production in the ocean -- which should lead to a better understanding of the direct and indirect interactions among the nitrogen cycle, marine chemistry, and climate.
