These data sets contain gridded, almost biennual fields of oxygen, apparent oxygen utilization (AOU), and anthropogenic carbon over the subpolar North Atlantic from 1991 to 2018. Area: 45°N-65°N, 65°W-5°W. Grid: 0.5°longitude times 0.25°latitude, depth spacing 100 m. The input data for the gridded fields are from GLODAPv2.2020 (Olsen et al., 2020) and from three additional cruises (MSM53 (Kieke et al., 2020), MSM64 (Steinfeldt et al. (2020a) and MSM73 (Steinfeldt et al., 2020b)). The gridding has been done by objective mapping as desribed in Rhein et al. (2015). Anthropogenic carbon has been inferred from transient tracers (CFCs and SF6) using transit time distributions according to Steinfeldt et al. (2009). Gaps in the biennual fields have been filled by gridding all data from the respective pentade, and remaining gaps by gridding all data.
