“…These new sensors will allow the measurement of sea surface height features at submesoscale, a scale already attained by ocean color (see Gaultier et al, 2013) or SST (sea surface temperature) sensors. Such high-resolution measurements of the sea surface, complemented by high-resolution in-situ measurements, such as VM-ADCP current profiling, seasoar or glider hydrological profiling, or seismic oceanographic transects, and the worldwide, intensive ARGO program of deep-ocean profilers, will provide a three-dimensional picture of surface and of subsurface mesoscale or submesoscale structures in the ocean (see also Filyushkin and Sokolovskiy, 2001;Bashmachnikov et al, 2012Bashmachnikov et al, , 2013Bashmachnikov et al, , 2014. Such highresolution and synoptic databases will allow a complete validation of simple process studies.…”
