Abstract :
[en] The present study is aimed at bringing together the benefits of different approaches for extracting information on surface currents from satellite-derived datasets and ocean data reanalysis. As a region of interest, we use the Western Mediterranean, which is having a peculiar pattern of surface circulation, due to the inflow of Atlantic water through the Strait of Gibraltar. Among the data analysed in this study, there are fields of sea surface temperature (SST) as well as different datasets on surface currents retrieved from satellite altimetry data, satellite imagery and their synergy. In particular, we analyse (i) fields of geostrophic currents retrieved from a gridded sea level anomaly (SLA) data product, (ii) the data on total surface currents derived in the framework of the GlobCurrent project, and (iii) the data provided by reanalysis. Special attention is being paid to the performance of different datasets in manifesting largest mesoscale eddies of the region of interest. As a result of the comparison performed, the general scheme of surface circulation in the region of interest was updated. Main novelties proposed by the renewed scheme concerns the number of cyclonic gyres presenting in the field of surface currents.
