Water circulation induced by the wind in the inner part of a Galician ría (NW Spain) : winter and spring situations
The wind effect on water circulation was described by means of hydrodynamical measurements carried out in the Ría de Pontevedra (NW of Spain) from February to July 1998. The samples were measured at an anchored station situated in the inner part
of the ría. It was observed a clear predominance of wind in the main estuary axis direction. Wind speeds higher than 4 m.s-1 are able to dominate the current at surface layers. Easterly winds force water to leave the estuary at surface layers while westerly
winds force water to enter it.

Quantitative method for the calculation of the environmental impact on the quality of coastal and estuarine waters using the analysis of principal components (PCA) of multivariant statistics

This paper proposes a quantitative method for the calculation of the environmental impact on the quality of coastal and estuarine waters of the Basque Country (Spain). The calculation has been made by means of multivariant statistics, specifically
using the analysis of principal components (PCA) it is based on previous methods developed for the Mediterranean coasts, (Niell et al., 1988). Data coming from a network of monitoring and quality control of coastal waters of the Basque Country have been
used. The average environmental impact in coastal and estuarine waters of the Basque Country vary from 25 to 50% in general. Few locations like the Nervión, Deba and ()iartzun estuaries show levels above 50 per cent.

Winter phytoplankton blooms within the Gironde plume waters in the bay of Biscay

Demersal species distributions were studied in relation to the dynamics and water masses patterns in the bay of Biscay and Celtic Sea. Well-defined mesoscale cyclonic-anticyclonic patterns and their links with the hake recruitment distribution
are described. In addition, the characteristics of bottom water masses have been examined in relation with the distribution of two species of megrim.

dead fauna not usually found in the sampling area in natural conditions, as it is the case of blue whiting (Microme sistius poutassou) and the galatheid Munida spp., usually found in deeper waters. A total of 319 stomach contents were analysed from 14
