The data were distributed to hypoxia researchers in near real time and used to generate bottom DO maps as part of the Hypoxia Watch Project (http://www.ncddc.noaa.gov/hypoxia/). The profiles were acquired with a Sea-Bird Model SB9 profiler equipped with pressure, temperature, conductivity, fluorescence, and beam transmission sensors. The data were processed with Sea-Bird software using the standard processing protocol developed by the Mississippi Laboratories. Water temperature, beam transmission, and derived salinity, DO and DO percent saturation, and density were retained in the processed files. SAS software was used to extract the bottom DO and other relevant data (e.g., date, time, position, and station number) and format the data as comma-delimited ASCII files. This dataset is available to the public for a wide variety of uses including scientific research and analysis. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0155488 Preview graphic PNG 0155488 NCEI ACCESSION NUMBER 2016-03-03 publication DISSOLVED OXYGEN theme NODC DATA TYPES THESAURUS CTD instrument NODC INSTRUMENT TYPES THESAURUS profile theme NODC OBSERVATION TYPES THESAURUS NOAA Ship Oregon II platform NODC PLATFORM NAMES THESAURUS NOAA Southeast Fisheries Science Center Pascagoula Laboratory dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS NOAA Southeast Fisheries Science Center Pascagoula Laboratory dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS GROUNDFISH BOTTOM TRAWL SURVEYS Southeast Area Monitoring and Assessment Program (SEAMAP) project NODC PROJECT NAMES THESAURUS Caribbean Sea Coastal Waters of Alabama Coastal Waters of Florida Coastal Waters of Louisiana Coastal Waters of Mississippi Coastal Waters of Texas Florida Keys National Marine Sanctuary Flower Garden Banks National Marine Sanctuary Gulf of Mexico North Atlantic Ocean place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/NMFS/SEFSC > Southeast Fisheries Science Center, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 23 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

The data were processed with the Sea-Bird software modules Data Conversion, Filter, Loop Edit, Derive, Bin Average, and Strip. Water temperature, beam transmission, and derived salinity, dissolved oxygen (DO), DO percent saturation, and density were retained in the processed profiles. SAS software was used to extract the bottom DO and other relevant data (e.g., date, time, position, and station number) and format the data as comma-delimited ASCII files.; Data Quality Information: Graphical analysis and software error traps were used to insure that the data were within acceptable ranges and that the station number, position, time, and water depth data had been correctly recorded in the header of each file. At the beginning of each deployment, the profiler was lowered to a depth of 2-3 meters to allow the conductivity cell to acclimate for a total of three minutes. The data acquired during the acclimation period was deleted prior to processing with Sea-Bird software. Winkler reference dissolved oxygen (DO) titrations were performed periodically to verify the DO readings measured by the electronic sensors on the profiler asNeeded Metadata are developed, maintained and distributed by NCEI. Updates are performed as needed to maintain currentness.
