This dataset consists of trawl and epibenthic sampling in turtlegrass-dominated seagrass beds of the northern Gulf of America, including Lower Laguna Madre, TX; Coastal Bend, TX; Chandeleur Islands, LA; St. George Sound, FL; Cedar Key, FL, and Charlotte Harbor, FL. The dataset consists of multiple .csv files containing nekton abundance, biomass, and size data, habitat characteristics including seagrass density and measurements, and abiotic measures of water quality.

This dataset consists of stable isotope data from turtlegrass-dominated seagrass beds of the northern Gulf of America (formally the Gulf of Mexico), including Lower Laguna Madre, TX; Coastal Bend, TX; Chandeleur Islands, LA; St. George Sound, FL; Cedar Key, FL, and Charlotte Harbor, FL. Data are in spreadsheet format.

This dataset presents results from surface-tethered drifting sediment traps deployed in 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.

This project assesses the use of turtlegrass by finfish and shellfish across the northern Gulf Mexico and evaluates the specific ways seagrass supports blue crabs, a commercially important species.

This dataset presents results from zooplankton net tows taken in 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). 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-fractioned 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.

This data set contains trawl information from collections near the West Pointe a la Hache siphon in south Louisiana. Species composition (fishes and macroinvertebrates), abundance, biomass and lengths are reported, along with salinity, temperature and dissolved oxygen data. Data are in spreadsheet format.

This dataset presents results from flow cytometry samples collected in the euphotic zone in 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). Flow cytometry results include abundances of phytoplankton taxa (Prochlorococcus, Synechococcus, Photosynthetic Eukaryotes) and non-pigmented bacteria (HBACT).

This dataset presents results of dissolved inorganic nutrient concentration analyses made on water column samples collected in 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). Dissolved inorganic nutrient concentration measurements include nitrate+nitrite (NO3-+NO2-), ammonium (NH4+), and soluble reactive phosphorus (PO43-).
