Sea and ocean names in ThermoGlobe are calculated from reported site locations using the IHO Sea Areas, version 3 shapefile downloaded from in August of 2019. The source for the actual boundaries is the publication Limits of Oceans, Seas, Special Publication No. 23 published by the IHO in 1953. The dataset was composed by the Flanders Marine Data and Information Centre.

The table above describes the data currently within ThermoGlobe with no attempt to remove known geothermal or hydrothermally affected areas. For this reason it is likely more accurate to use the median, as opposed to the mean values from this table.
