Paper Abstract

The time-space distribution of chlorophyll concentration in the gulf of Cadiz (SW Spain) is analysed by using remotely sensed data from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) between 1998 and 2002. Climatological and monthly averages show more productive waters at the inner shelf, especially during winter-spring and fall blooms. This pattern is further confirmed by the modes obtained with an Empirical Orthogonal Function (EOF) decomposition of weekly chlorophyll composite images for the whole period. The first mode (10%) distinguishes several regions with patterns of variability correlated with oceanographic features in the area. It identifies a coastal zone between Huelva and Cadiz which is strongly coupled to local zonal winds where west and easterlies induce an increase and decrease of the chlorophyll respectively. Chlorophyll concentration of this area is also sensitive to precipitation.
