Oceanographic data from twelve fixed ship-based time-series programs were synthesized into a pilot product with focus on biogeochemical essential ocean variables (BGC-EOV). Measurements of dissolved oxygen, dissolved inorganic nutrients, inorganic carbon (pH, TALK, DIC, pCO2), particulate matter, and DOC were compiled from the time series programs listed below.

Methods, Sampling, and Instruments are dependent on individual time-series programs, and often vary within a single time series program from cruise-to-cruise.

Instruments are listed in the section below, with detailed metadata available at ODIS (https://oceaninfohub.org/odis/).
