Deciphering the redistribution of excess heat in the North Atlantic: time series of ocean heat content at 25N from 1850 to present

This data set is related to the article "Deciphering the redistribution of excess heat in the North Atlantic" in Communication Earth and Environment by Marie-José Messias and Herlé Mercier. It provides time series of ocean heat content (OHC) at 25°N in the Atlantic Ocean from 1850 to 2018 in four layers (0–700m, 700–2000m, 2000–4000m, 4000m–bottom) and associated errors. The contributions of 9 source regions (Arctic Ocean, Nordic Seas, Labrador and Irminger Seas, north-eastern subpolar gyre, Mediterranean Sea, subtropical and tropical North Atlantic, subtropical and tropical South Atlantic, Sub-Antarctic Ocean and Antarctic Ocean) to the surface-to-bottom OHC at 25°N from 1850 to 2018 are also provided.
