Upper Ocean Heat Content Anomaly

Upper Ocean Heat Content Anomaly

Analyzing the heat content of the world's oceans

The plot shows the 22-year trend in 0-700 m Ocean Heat Content Anomaly (OHCA) estimated from in situ data ( Lyman et al. 2010, Lyman and Johnson 2014). The error bars include uncertainties from baseline climatology, mapping method, sampling, and XBT bias correction.

Shown above is the 22-year trend in 0-700 m Global Ocean Heat Content Anomaly (OHCA) estimated from in situ data ( Lyman et al. 2010, Lyman and Johnson 2014). The error bars include uncertainties from baseline climatology, mapping method, sampling, and XBT bias correction. Click on the plot to download a PDF version.

Recent estimates are based primarily on Argo profiling CTD float data. Historical data are from XBTs, CTDs, moorings, and other sources.  Satellite altimeter data from Aviso are used to estimate errors. Additional displays of the upper OHCA are available in the Plots section.
