        abstract:  This dataset contains chemical and physical data collected on R/V Nancy Foster during cruises NF1704 and NF1802 in the Gulf of Mexico from 2017-05-11 to 2018-05-19. These data include Ammonium, Dissolved Organic Nitrogen, d15N, depth, nitrate plus nitrite, reactive phosphorus (PO4), sigma-theta, water pressure, and water temperature. The instruments used to collect these data include Chemiluminescence NOx Analyzer, Fluorometer, Isotope-ratio Mass Spectrometer, and UV Spectrophotometer-Shimadzu. These data were collected by Angela N. Knapp of Florida State University and Michael R. Landry of University of California-San Diego 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)" project 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 2021-01-04. The following is the text of the dataset description provided by BCO-DMO: BLOOFINZ-GoM Nutrients, Nitrate isotopes, DON isotopes Dataset Description: Acquisition Description: Water column samples were collected by Niskin bottle on a CTD rosette (“CTD profile”) in the North/Central Gulf of Mexico during Nancy Foster cruises (NF17-04, NF18-02) in May 2017 and May 2018, as part of the NOAA RESTORE (aka BLOOFINZ-GoM) project. All samples were 0.2 µm filtered into pre-washed HDPE bottles which were frozen at -20 degrees Celsius until analysis on land. Acquisition and associated instruments: Nitrate+nitrite concentration was measured on a Thermo 42i NOx analyzer Nitrate+nitrite d15N was measured using a Thermo Finnigan Delta V isotope ratio mass spectrometer. Phosphate concentration was determined using a Shimadzu UV-1800 uv-vis spectrophotometer. Ammonium concentration was determined using a Turner Trilogy fluorometer.
        purpose:  This dataset is available to the public for a wide variety of uses including scientific research and analysis.

            description:  spectrophotometer, optical spectrometer, spectrograph or spectroscope An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials. Butler, L. R. P.; Laqua, K. (1995). "Nomenclature, symbols, units and their usage in spectrochemical analysis-IX. Instrumentation for the spectral dispersion and isolation of optical radiation (IUPAC Recommendations 1995)". Pure Appl. Chem. IUPAC. 67 (10): 1725–1744. doi:10.1351/pac199567101725. A spectrometer is the general term for describing a combination of spectral apparatus with one or more detectors to measure the intensity of one or more spectral bands."
