This atlas consists of a description of data analysis procedures and horizontal maps of climatological distribution fields of dissolved oxygen (O2), apparent oxygen utilization (AOU), and dissolved oxygen saturation (S2O) at selected standard depth levels of the world ocean on a one-degree latitude-longitude grid. The aim is to illustrate large-scale characteristics of the distribution of dissolved oxygen. The oceanographic data fields used to generate these climatological maps were computed by objective analysis of scientifically quality-controlled historical dissolved oxygen data in the World Ocean Database 2018 collected on or after 1960. Distribution concentration maps are presented for climatological composite periods (annual, seasonal, monthly, seasonal and monthly difference fields from the annual mean field, and the number of observations) at 102 standard depths. We also provide estimates of the basin-scale uncertainty of the WOA18 O2 objectively analyzed annual fields.
