Ocean heat content and the importance of the deep ocean

TOA and OHC
The ocean is not a bathtub
- Mechanisms exist within climate models, which are capable of mixing heat down to the deep ocean on decadal timeframes.
- Current observations of the 700-m surface layer have shown little warming, or even cooling, in the last 8 years; but the surface layer down to 1,500 m has shown significant warming, which seems to support the modeling
- Climate modeling and observations indicate that to fully understand the global enery budget (where all the heat is going) we need to include measurements of the deep oceans. The surface layers, even down to 700 m, are not robust indicators of total OHC.
