This NCEI accession contains estimates of water mass contributions to the GLODAPv2 Atlantic data. 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).
