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). The oligotrophic Gulf of Mexico is one of the only regions where Atlantic Bluefin Tuna (ABT) spawn. This region is nutrient poor and low productivity leads to relatively low abundances of zooplankton. The goal of this project is to investigate the marine foodweb from nutrients to larval ABT to investigate potential processes controlling larval production and survival. Hypotheses include bottom-up regulation of primary productivity by nutrient availability, alternating dependence on upwelled nitrate or nitrogen fixation as sources of new nitrogen, and modifications to zooplankton food webs that favor productivity of the preferred prey of ABT. To investigate these goals, we are conducting extensive investigation of nitrogen cycling through the marine ecosystem with a particular focus on nitrogen isotopes. These cruises were part of a NOAA RESTORE funded cruise intended to investigate the epipelagic marine nitrogen cycle, plankton dynamics, and impacts on larval tuna growth and survival. Sediment trap data contained in this dataset enables estimates of the total flux of carbon and nitrogen from the surface ocean, the relative proportion of phytoplankton and fecal material in the sinking material, and the proportion of this material potentially supported by upwelled nitrate or nitrogen fixation. Mesozooplankton results in this dataset provide biomass and grazing estimates for analyses of plankton community structure, food web fluxes, and modeling. Dissolved inorganic nutrient concentration data contained in this dataset establish nutrient distributions in the region of interest, which informs our understanding of nutrient availability for the base of the food web. Flow cytometry data contained in this dataset enables estimates of the phytoplankton community composition in the euphotic zone of our study region. Data in this accession was funded by the NOAA RESTORE Science Program for the project "Effects of nitrogen sources and plankton food-web dynamics on habitat quality for the larvae of Atlantic Bluefin Tuna in the Gulf of Mexico" implemented by the NOAA NMFS Southeast Fisheries Science Center.

NOAA National Centers for Environmental Information custodian CTD CTD Conductivity-Temperature-Depth probe Flow Cytometer Flow Cytometer A method to enumerate bacterial and phytoplankton cells in seawater and estimate their spherical diameter Flow cytometers are laboratory based instruments used to measure cells and particles from aqueous samples. The instrument was initially developed for analysis of Human blood cells for medical purposes, but this technology was adopted by the ocean science community by several investigators, principally Penny Chischolm out of the Massachusetts Institute of Technology, in late 20th century. Since then, the technique has been broadly applied, and it is a unique measurement of microbial populations in the ocean because it provides one at a time measures of cells, to extrapolate features such as fluorescence and cell size. Flow cytometers have been adapted for a number of oceanographic applications such as ship board measurement, and more precise measurement of planktonic fractions. Additionally, the flow cytometer has been adapted for in-situ deployment (see the corresponding nodc instrument code). fluorometer fluorometer fluorometer mass spectrometer mass spectrometer Instrument that measure the massess and relative concentrations of atoms and molecules net - plankton net net - plankton net net - plankton net net - zooplankton net net - zooplankton net net - zooplankton net Niskin bottle Niskin bottle Device for obtaining samples of seawater at a specific depth Why special entry for Niskin bottle but no entry for Nansen bottle? trap - sediment trap - sediment one of several specific type of instrument used to capture sediment NOAA Ship Nancy Foster Title: NOAA Ship Flag: United States of America Vessel Type: Research Vessel (Environmental) DOB: May 1991 IMO: 8993227 Former Name: Agate Pass (YTT-12) (2002)
