Distribution of different depth zones within the world ocean and seas and EEZ. The EEZ analysed this study includes all the area between a state’s coastline (delineated as zero depth based GEBCO_2024 bathymetry grid) and the outer limit of the corresponding EEZ.
Territorial claims by sovereign states in the Southern Ocean are not considered EEZ.
The depth zones are based on GEBCO_2024 bathymetry grid.
