Upper Ocean Heat Content Anomaly

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.

Historical data are from XBTs, CTDs, moorings, and other sources.    Additional displays of the upper OHCA are available in the Plots section.

Argo Recent estimates are based primarily on Argo profiling CTD float data. Satellite altimeter data from Aviso are used to estimate errors
