World Ocean Atlas 2018, Volume 3: Dissolved Oxygen, Apparent Oxygen Utilization, and Dissolved Oxygen Saturation

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 ( S O2 ) 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.
