Resumo
In this paper, winter hydrography and dynamics off western Galicia is described combining on board and satellite measurements during downwelling season. In upper waters (0-50 m), four features have been distinguished by their different physical properties, being from coast to ocean: a local upwelling near Cape Silleiro originated by divergence of coastal currents, the Western Iberian Buoyant Plume (WIBP), mainly originated by the Miño Miño runoff, a transitional frontal zone with great mesoscale activity, and finally the Iberian Poleward Current (IPC), which are representative of this zone in winter. The high correspondence between on board surface fluorescence and satellite chlorophyll a measurements is quantified. An analysis of spatial variability of central, intermediate and deep water masses is also included.
