The major water masses in the Atlantic Ocean were characteristics as Source Water Types (SWTs) from their formation areas and map out their distributions. The SWTs are described by six properties taken from the biased adjusted data product GLODAPv2, including both conservative (Temperature and Absolute Salinity) and non-conservative (oxygen, silicate, phosphate and nitrate) properties. The distributions of the water masses are estimated by using the Optimum Multi-parameter (OMP) model and the data are contained in the file that has the same length and order as the GLODAPv2 Atlantic data file. The following water masses were considered: Antarctic Intermediate Water (AAIW), Subarctic Intermediate Water (SAIW) and Mediterranean Water (MW), North Atlantic Deep Water (NADW, divided into its upper and lower components), Labrador Sea Water (LSW), Iceland-Scotland Overflow Water (ISOW), Denmark Strait Overflow Water (DSOW), Antarctic Bottom Water (AABW), North East Atlantic Bottom Water (NEABW), Circumpolar Deep Water (CDW), and Weddell Sea Bottom Water (WSBW). 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:0225455 Preview graphic PNG 0225455 NCEI ACCESSION NUMBER 2021-02-04 publication SALINITY WATER TEMPERATURE theme NODC DATA TYPES THESAURUS CTD Niskin bottle salinometer temperature sensor instrument NODC INSTRUMENT TYPES THESAURUS chemical derived products discrete sample physical theme NODC OBSERVATION TYPES THESAURUS VARIOUS CHARTERED VESSELS platform NODC PLATFORM NAMES THESAURUS GEOMAR Helmholtz Centre for Ocean Research Kiel dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS GEOMAR Helmholtz Centre for Ocean Research Kiel dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS GLOBAL OCEAN DATA ANALYSIS PROJECT (GLODAP) project NODC PROJECT NAMES THESAURUS Mediterranean Sea North Atlantic Ocean South Atlantic Ocean Southern Ocean place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication DE/GEOMAR > GEOMAR - Helmholtz Centre for Ocean Research Kiel, Germany 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.
