Subpolar North Atlantic ocean heat content (surface to 1000m) using the EN4.2.2 temperature data set

Monthly ocean heat content (surface to 1000m) in the North Atlantic Subpolar region, from 1950 to 2020, calculated using the EN4.2.2 temperature data set. This calculation of ocean heat content used potential enthalpy (from TEOS10) instead of potential temperature, which removes the need for a fixed specific heat capacity. Density was from insitu density rather than a fixed value. This was funded by the Natural Environment Research Council (NERC) under the Atlantic Climate System Integrated Study (ACSIS) project (NE/N018044/1).
