Research Abstract
In order to examine the role of mesoscale eddies in long-term global ocean heat uptake from the atmosphere, we attempted to obtain temporal evolutions of vertical temperature profiles in a cold eddy by making ocean profiling floats trapped in the cold eddy south of the Kuroshio Extension. The observed temperature profiles indicated the subsurface warming during late winter and early spring, and this warmed water was found to remain in the subsurface even in early summer when the effect of the surface heat exchange is limited in the shallow mixed layer . Our observations suggest that the exchanged heat from the atmosphere to the mixed layer was stored in the subsurface ocean in the cold eddy, where direct heat exchange with the atmosphere is impossible, contributing to global ocean heat uptake.
