dc.description.abstract	The dynamics of Gymnodinium catenatum and Dinophysis acuta was studied during the development 'of a weak upwelling event observed in a repeated coverage of a combined CTD/plankton transect at 41°05'N, off the coast of Portugal. Both species were mainly distributed in the surface wind driven layer within the region of the equatorward coastal jet. Wind induced mixing, offshore transport and vertical motions were reflected in the distribution and the number of cells. It was generally observed that wind relaxation was associated with blooming conditions and shellfish toxicity, while active winds gave rise to dispersion of cells, reduction of their number and detoxification of bivalves
