This dataset compiles all available ship-based biogeochemical measurements at the Cape Verde Ocean Observatory (CVOO) into one merged dataset. The irregular measurements at CVOO started in 2006 and are still ongoing aiming at increasing data coverage in a key region for air-sea interaction. The station has a bottom depth of 3600 m and lies in the center of the Cape Verde Fontal Zone, resulting in large variations of the present oligotrophic water masses as well as an oxygen-poor layer between 400 m to 500 m. The dataset includes oxygen, nutrients, dissolved inorganic carbon, total alkalinity, and particulate organic matter measurements, and ancillary ctd-data are also included. The research vessels used and the exact measurement methods as well as the laboratories varied on a cruise-to-cruise basis, accordingly the data has undergone additional quality-control checks. The checks included flier detection (WOCE-flagging) and crossover-analysis that resulted in bias corrections.
