Abstract
Hydrographic data collected during the cruise HIDROPRESTIGE were combined with meteorological and dynamic data provided
by remote sensors and drifting/moored buoys, to describe the surface circulation of the Northern Iberian basin in March–April 2003. Sea
surface winds transported the floating Prestige oil slicks from the sinking area to the continental slope off the Rías Baixas in 1/2 month:
the surface current intensity was 2% of the wind intensity and it was rotated clockwise 5 from the wind direction. Mesoscale cyclonic and
anticyclonic structures west of 10º W increased the residence time of oil patches in the Northern Iberian basin, as compared with the
expected southwards flow of the Iberian current (IC). On the other hand, the Iberian poleward current (IPC) formed a marked surface
front with coastal waters, preventing the entry of fuel oil into the rías. PAHs in the surface layer during the cruise were <0.5 ug L- 1,
except in the Galicia bank ( 1 ug L- 1; where the Prestige ...
