Última Surface flux and ocean heat transport convergence contributions to seasonal and interannual variations of ocean heat content ArchiMer Roberts, C. D.; Palmer, M. D.; Allan, R. P.; Desbruyeres, Damien; Hyder, P.; Liu, C.; Smith, D.. We present an observation-based heat budget analysis for seasonal and interannual variations of ocean heat content (H) in the mixed layer (H-mld) and full-depth ocean (H-tot). Surface heat flux and ocean heat content estimates are combined using a novel Kalman smoother-based method. Regional contributions from ocean heat transport convergences are inferred as a residual and the dominant drivers of H-mld and H-tot are quantified for seasonal and interannual time scales. We find that non-Ekman ocean heat transport processes dominate H-mld variations in the equatorial oceans and regions of strong ocean currents and substantial eddy activity. In these locations, surface temperature anomalies generated by ocean dynamics result in turbulent flux anomalies that...

Sea surface salinity (SSS) from the Aquarius and SMOS satellite missions displays a steady increase of ~1psu over the entire northwestern Atlantic shelf south of Nova Scotia during the 2011-2015. Put in the context of longer ocean profile data the results suggest that mixed layer salinity and temperature north of the Gulf Stream experience positively correlated shelf-wide interannual oscillations (1psu/2degC). Salty and warm events occur coincident with anomalous easterly-southeasterly winds and Ekman transport counteracting the mean southwestward shelf currents. They are coincident with the weakening of both branches of the Scotian Shelf Current (SSC), but only moderately correlate with shifts of the Gulf Stream North Wall. This suggests that salt...
