    • Global Ocean Data Analysis Project version 2.2019 (GLODAPv2.2019) (NCEI Accession 0186803)

    Metadata Updated: July 1, 2025

    This dataset consists of GLODAPv2.2019 data product composed of data from 840 scientific cruises covering the global ocean between 1972 and 2017. It includes full depth discrete bottle measurements of salinity, oxygen, nitrate, silicate, phosphate, dissolved inorganic carbon (TCO2), total alkalinity (TAlk), pH, chlorofluorocarbons (CFC-11, CFC-12, CFC-113, and CCl4), various isotopes and organic compounds. It was created by appending data from 116 cruises to GLODAPv2 (Olsen et al., 2016, NCEI Accession 0162565). The data for salinity, oxygen, nitrate, silicate, phosphate, TCO2, TAlk, pH, CFC-11, CFC-12, CFC-113, and CCl4 were subjected to primary and secondary quality control. Severe biases in these data have been corrected for, and outliers removed. However, differences in data related to any known or likely time trends or variations have not been corrected for. These data are believed to be accurate to 0.005 in salinity, 1% in oxygen, 2% in nitrate, 2% in silicate, 2% in phosphate, 4 µmol kg-1 in TCO2, 4 µmol kg-1 in TAlk, and for the halogenated transient tracers: 5%.
