Compilation of dissolved organic matter (DOM) data obtained from global ocean observations

Measurements of dissolved organic matter (DOM) obtained from the global ocean are provided. DOM data generated by many international laboratories are typically made available in diverse, regional data archives, making it difficult for the data value to be maximised. The effort here was to make ship-collected bottle data accessible more directly and in uniform format. The emphasis was on spatial coverage of the global ocean, so neither the well-known time-series data nor coastal waters are well represented. Variables include DOC, TDN, isotopes, select wavelengths of CDOM, and composition; hydrographic data, the inorganic carbon system, and anthropogenic and natural tracers. Data are from 230 cruises, providing 94324 measures of DOC and 29113 measures of TDN (limited to the surface 250 m).
