[25-Aug-2017] The subpolar North Atlantic (SPNA) reversed trends in ocean heat content from warming during 1994-2004 to cooling over 2005-2015. ECCO V4r3 reveals that this reversal is the result of anomalous horizontal midlatitude gyre circulation acting on the mean temperature gradient, rather than changes in overturning circulation. Results have implications for decadal predictability.
