This data product is composed of data from 724 scientific cruises covering the global ocean. It includes data assembled during the previous interior ocean data synthesis efforts GLODAPv1.1 (Global Ocean Data Analysis Project version 1.1) in 2004, CARINA (CARbon IN the Atlantic) in 2009/2010, and PACIFICA (PACIFic ocean Interior CArbon) in 2013, as well as data from an additional 168 cruises. NCEI Accession 0162565 includes discrete bottle measurements of salinity, oxygen, nitrate, silicate, phosphate, dissolved inorganic carbon, total alkalinity, pH, CFC-11, CFC-12, CFC-113, and CCl4, carbon isotopes and chlorophyll. These data have been subjected to extensive primary and secondary quality control which included systematic evaluation of bias, and adjustments have been applied to remove significant biases, respecting occurrences of any known or likely time trends or variations.
