USING SAR IMAGES FOR DETECTION OF A SURFACE POLEWARD CURRENT OFF THE WEST COAST OF THE IBERIAN PENINSULA
The surface circulation off the western coast of the Iberian Peninsula is strongly influenced by the atmospheric pressure distribution in the North Atlantic. During the winter season, the combination of the onshore Ekman transport and the geostrophic adjustment of the large-scale oceanic zonal flow...
