    • A new global interior ocean mapped climatology: the 1° × 1° GLODAP version 2 from 1972-01-01 to 2013-12-31 (NCEI Accession 0286118)

    Metadata Updated: March 1, 2026

    This data package contains a mapped climatology (GLODAPv2.2016b) of ocean biogeochemical variables based on the 2016 version of the GLODAP version 2 data product, which covers all ocean basins over the years 1972 to 2013. The quality-controlled and internally consistent GLODAPv2 was used to create global 1° × 1° mapped climatologies of salinity, temperature, oxygen, nitrate, phosphate, silicate, total dissolved inorganic carbon (TCO2), total alkalinity (TAlk), pH, and calcium carbonate (CaCO3) saturation states using the Data-Interpolating Variational Analysis (DIVA) mapping method (Troupin et al., 2012). Error fields are calculated using the clever poor mans error calculation method in DIVA (Beckers et al., 2014). Climatologies were created for 33 standard depth levels from surface to 5500 meters. The conceivably confounding temporal trends in TCO2 and pH due to anthropogenic influence were removed prior to mapping by normalizing these data to the year 2002 using first-order calculations of anthropogenic carbon accumulation rates. We additionally provide maps of accumulated anthropogenic carbon in the year 2002 and of preindustrial TCO2. For all variables, all data from the full 1972–2013 period were used, including data that did not receive full secondary quality control.
