GOBAI-O2 : Gridded Ocean Biogeochemistry from Artificial Intelligence - Oxygen.

A gridded data product of ocean oxygen concentrations at monthly resolution on 58 depth levels from 2004 to 2023. GOBAI-O2 is constructed from two types of machine learning algorithms, trained using Argo O2 data and discrete O2 measurements from the GLODAP database, and applied to temperature and salinity grids from Roemmich and Gilson (2009).
