Oceanic heat content (OHC) is the heat stored in the ocean. Oceanography and climatology are the science branches which study ocean heat content. Changes in the ocean heat content play an important role in the current sea level rise, because of thermal expansion. It is with high confidence that ocean warming accounts for 90% of the energy accumulation from global warming between 1971 and 2010.
Definiion and measurement:
- Water Density - sea water specific heat capacity, h2 - bottom depth h1 - top depth
OHC is computed from temperature measurements often taken with a Nansen bottle. The ARGO float project deployed 3000 floaters around the world's oceans which periodically dive to take temperature and salinity measurements. The world ocean database project is the largest database for temperature profiles from all of the world’s oceans.
