| Title: | Nitrate uptake from in-situ incubations conducted during NOAA Ship Nancy Foster cruises NF1704 and NF1802 in the Gulf of Mexico in May of 2017 and 2018 (NCEI Accession 0278288) |
| Abstract: | This dataset contains chemical data collected on R/V Nancy Foster during cruises NF1704 and NF1802 in the Gulf of Mexico from 2017-05-11 to 2018-05-18. These data include Ammonium, Nitrate, depth, and particulate organic nitrogen. The instruments used to collect these data include CTD profiler, Elemental Analyzer, Isotope-ratio Mass Spectrometer, and Niskin bottle. These data were collected by Michael Stukel and Thomas Kelly of Florida State University as part of the "Collaborative Research: Mesoscale variability in nitrogen sources and food-web dynamics supporting larval southern bluefin tuna in the eastern Indian Ocean (BLOOFINZ-IO)" and "Effects of Nitrogen Sources and Plankton Food-Web Dynamics on Habitat Quality for the Larvae of Atlantic Bluefin Tuna in the Gulf of Mexico (GoMex Tuna Foodweb B)" projects and "Second International Indian Ocean Expedition (IIOE-2)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2021-04-06. The following is the text of the dataset description provided by BCO-DMO: Dataset Description: In addition to the funding sources listed in the "Funding Source" section, this dataset was partially funded by: National Oceanic and Atmospheric Administration's RESTORE Program Grant (Project Title: Effects of nitrogen sources and plankton food-web dynamics on habitat quality for the larvae of Atlantic bluefin tuna in the Gulf of Mexico) under federal funding opportunity NOAA-NOS-NCCOS-2017-2004875, including NOAA JIMAR Cooperative Agreement, award #NA16NMF4320058, NOAA CIMAS Cooperative Agreement, award #NA15OAR4320064, and NOAA CIMEAS Cooperative Agreement, award #NA15OAR4320071. |

| Supplementary information: | Acquisition Description: Nitrate uptake rates were measured at 6 depths spanning the euphotic zone (surface to deep chlorophyll maximum). Two incubation bottles (2.7 L) per depth were filled from Niskin rosettes and spiked with 15 NO 3 - (final concentration of 10 or 8 nmol L -1 on NF17 and NF18, respectively). Bottles were then incubated for 24 h on an in situ incubation array (Landry et al. 2009). Upon recovery, incubations were immediately vacuum filtered onto pre-combusted 25-mm GF/F filters in the dark. Filters were rinsed with filtered seawater, wrapped in foil and stored at 80°C. On land, samples were fumigated with HCl vapor to remove inorganic carbon, dried, and placed inside a tin cup for C/N and isotopic analysis at the UC Davis stable isotope facility. Nitrate uptake was computed following recommendations in Stukel (2020). For additional details, see Yingling et al. (submitted). |
