Ocean Heat Content

Sample product image of NOAA CDR Ocean Heat Content product; it depicts a line graph of global ocean heat content in joules; it has three line traces one in red which is the 3-month average, one in black which is the yearly average, and finally one in blue which is the Pentadal average through 2016-2020.

This dataset provides scientific researchers a high quality Climate Data Record (CDR) of Ocean Heat Content.

Quantification of ocean heat content (OHC) change over time is imperative for understanding the Earth’s energy budget and climate change. The OHC CDR is a set of time series of ocean heat content anomaly (OHCA) from 1955 to present on a 3-monthly, yearly, and pentadal (five-yearly) time scale. OHCA is calculated from the surface to 700m and from the surface to 2000m. The 0-700m field is where the largest portion of heat sequestration occurs and coincides with the deepest depth of the expendable bathythermograph (XBT) the main component of the observing system for subsurface ocean temperatures 1967-2002. The 0-2000m field matches the domain of the Argo floats, the main observing system 2003-present. The product includes time series of OHCA for the global ocean and each of the major basins (Atlantic, Pacific, and Indian). Time series for the global ocean and basins are also available divided by hemisphere (Northern, Southern).
