NOAA RESTORE Science Program: Effects of nitrogen sources and plankton food-web dynamics on habitat quality for the larvae of Atlantic Bluefin Tuna in the Gulf of Mexico - biogeochemistry, dissolved inorganic nutrient, mesozooplankton, phytoplankton, and bacteria data from 2017-05-10 to 2018-05-19

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: May 06, 2026 at 06:46 AM | Dataset Last Updated: June 10, 2021 at 12:00 AM
This dataset presents results from surface-tethered drifting sediment traps, zooplankton net tows, dissolved inorganic nutrient concentration analyses made on water column samples, and flow cytometry samples collected in the euphotic zone, from the open ocean Gulf of Mexico during cruises of the NOAA Ship Nancy Foster, May 10-30, 2017 (NF17), and May 5-19, 2018 (NF18). Sediment trap results include particulate organic carbon flux, particulate nitrogen flux, carbon isotope ratio of sinking organic matter (13C/12C), nitrogen isotopes of sinking material (15N/14N), chlorophyll a flux, and phaeopigment flux. Mesozooplankton results include separate files for: 1) wet weight, dry weight, carbon and nitrogen biomass estimates for total zooplankton and five size fractions; 2) carbon and nitrogen percent dry weight, stable carbon (13C/12C) and nitrogen (15N/14N) isotope ratios of five size fractions; and 3) size-fractionated chlorophyll and phaeopigment gut pigment contents, pigment-based estimates of mesozooplankton grazing on phytoplankton in the euphotic zone (grazing m-2 h-1) and biomass-specific rates of grazing relative to zooplankton dry weight and carbon. Dissolved inorganic nutrient concentration measurements include nitrate+nitrite (NO3-+NO2-), ammonium (NH4+), and soluble reactive phosphorus (PO43-). Flow cytometry results include abundances of phytoplankton taxa (Prochlorococcus, Synechococcus, Photosynthetic Eukaryotes) and non-pigmented bacteria (HBACT).
