Upper Ocean Heat Content Anomaly
Analyzing the heat content of the world's oceans
Shown above is the 28-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.
