The Southeast Area Monitoring and Assessment Program (SEAMAP) is a State/Federal/university program for collection, management and dissemination of fishery-independent data and information in the southeastern United States.

These datasets consist of profile data collected by CTD casts in the northern Gulf of Mexico that are collected as part of the annual summer groundfish survey supported by the Southeast Area Monitoring and Assessment Program (SEAMAP). SEAMAP is a State/Federal/university program for collection, management and dissemination of fishery-independent data and information in the southeastern United States. Data are in Sea-Bird CNV format.

A total of 230 environmental profiles were acquired during the Southeast Area Monitoring and Assessment Program (SEAMAP) summer groundfish survey of the Western and North-central Gulf of Mexico conducted during June and July 2006 and aboard NOAA Ship Oregon II. The profiles were acquired between the 5 and 60 fathom isobaths at stations located east of the Mississippi River and in the area of Brownsville, Texas eastward to the Louisiana Bight. Maximum water depths recorded in the profile headers range from 8.8 to 245.0 meters with an average maximum depth of 39.7 meters. The survey is a stratified random design with depth interval, NMFS Statistical Subareas 11 through 21 and day and night as strata. The data were processed into 1 meter average depth bins of water temperature, salinity, dissolved oxygen (DO), DO percent saturation, fluorescence, transmittance, density, and number of data records. The profiles were quality controlled during and after the cruise.

This dataset contains sea water property (profile) data taken by Conductivity, Temperature, Depth (CTD) from NOAA Ship Nancy Foster during two merged collaborative fisheries oceanography surveys (described in detail below). Data cover 2016-05-10 to 2016-06-15 period. The vessel's Sea-Bird Electronics (SBE) 911plus CTD system was operated at 119 discrete station locations along the survey track. At each location, the CTD package was lowered from the surface to a predetermined depth, sampling continuously. The CTD was configured with a pressure sensor, dual temperature, conductivity, and dissolved oxygen sensors, a chlorophyll a (chl_a) fluorometer, a colored dissolved organic matter (CDOM) fluorometer, and an altimeter. The sensor package was attached to a frame configured with a 24-bottle water sampler and 10-liter Niskin water sampling bottles. The raw CTD data were post-processed to a final state using the SBE Data Processing Software package (Windows-based, publicly available at www.seabird.com). The specific subroutines applied to the data are outlined in the header of each ascii data file found in the dataset (.cnv files). The header of each file also includes the time and location of the cast. In addition to the ascii data in this data submission, .jpg plots of each CTD cast have also been included. These data were not calibrated to bottle samples and are considered final. The measured and derived parameters in this dataset are: Time of Cast (elapsed from start, s) Pressure (Digiquartz, db) Temperature (from primary sensor, ITS-90, deg C) Temperature (from secondary sensor, ITS-90, deg C) Conductivity (from primary sensor, S/m) Conductivity (from secondary sensor, S/m) Dissolved Oxygen Raw Voltage (from primary sensor, SBE 43, 0-5 VDC) Dissolved Oxygen Raw Voltage (from secondary sensor, SBE 43, 0-5 VDC) CDOM Relative Fluorescence (WET Labs CDOM Fluorometer, 0-5 VDC) CHL_A Relative Fluorescence (WET Labs ECO-AFL Fluorometer, 0-5 VDC) Altimeter (when in range, depth off the bottom, m) Depth (in salt water, m) Density (from primary sensors, sigma-theta, kg/m^3) Density (from secondary sensors, sigma-theta, kg/m^3) Potential Temperature (from primary sensors, ITS-90, deg C) Potential Temperature (from secondary sensors, ITS-90, deg C) Sound Velocity (from primary sensors, Chen-Millero, m/s) Sound Velocity (from secondary sensors, Chen-Millero, m/s) Dissolved Oxygen (from primary sensor, SBE 43, ml/l) Dissolved Oxygen (from primary sensor, SBE 43, mg/l) Dissolved Oxygen (from primary sensor, SBE 43, umol/l) Dissolved Oxygen (from primary sensor, SBE 43, umol/kg) Dissolved Oxygen (from secondary sensor, SBE 43, ml/l) Dissolved Oxygen (from secondary sensor, SBE 43, mg/l) Dissolved Oxygen (from secondary sensor, SBE 43, umol/l) Dissolved Oxygen (from secondary sensor, SBE 43, umol/kg) Salinity (from primary sensors, Practical, PSU) Salinity (from secondary sensors, Practical, PSU) The NOAA fleet cruise IDs for these two surveys are NF-16-02 and NF-16-03. However, the CTD were processed together and the cruise ID NF-16-02 refers to data from both cruises. A completed cruise track and project overviews are presented in the included supporting document: NF1602_and_NF1603_CTD_overview.pdf.

This dataset contains water temperature, salinity, and sound speed data collected for the OPR-J317-KR-18 project under contract with NOAA. Sea Bird Electronics SBE19plus CTD sensors were used for in-situ measurements through the water column. Casts were conducted at least once a day on board R/V C-Wolf and more often as needed. Dual CTDs were obtained periodically to ensure proper working order of sensors. Data are in ASCII (cnv) format.

This report contains results from the fifth cruise of the Marine Optical Characterization Experiment. A variety of spectroradiometric observations of the upper water column and atmosphere were made by investigators from the University of Miami, NOAA, CHORS, CICESE, Oregon State University, University of South Florida, UABC, NERSC and MLML. Data presented here were obtained by oceanographic CTD profiler: salinity, temperature, dissolved oxygen, beam attenuation and chlorophyll-a fluorescence; and by water samplers: total suspended matter and suspended organic carbon and nitrogen, salinity, and dissolved oxygen. Data were collected from 01 October 1999 to 21 October 1999.
