Argo, Temperature, and OHC

Guest Post by Willis Eschenbach I’ve been thinking about the Argo floats and the data they’ve collected. There are about 4,000 Argo floats in the ocean. Most of the time they are asleep, a thousand metres below the surface. Every 10 days they wake up and slowly rise to the surface, taking temperature measurements as…

An Ocean of Overconfidence

Guest Post by Willis Eschenbach I previously discussed the question of error bars in oceanic heat content measurements in “Decimals of Precision“. There’s a new study of changes in oceanic heat content, by Levitus et al., called “World Ocean Heat Content And Thermosteric Sea Level Change (0-2000), 1955-2010″ (paywalled here). It’s highlighted over at Roger…

In the comments to my previous post, I had put up a graphic showing how the January/February/March data for one gridcell varied by latitude…
