Paper Abstract

Conditions for primary production have been studied in Namibian waters during the period: October 1997-December 2003. The variables used have been: Sea Surface Temperature (SST) from the Advanced Very High Resolution Radiometer (AVHRR) and chlorophyll concentration from Sea-viewing Wide Field-of-view Sensor (SeaWiFS) imagery. Temporal, latitudinal analyses have been done for both variables in different spatial scales. Chlorophyll concentration presented a clear seasonality all along the Namibian coast. Summer and winter with maxima and minima respectively, these periods correspond to minimum and maximum upwelling intensity. These results indicate that primary production in this regions is not limited by nutrients, though it seems to be negatively affected by physical instability. Additionally north and south of 23°S a second peak of chlorphyll concentration is observed by at different seasons: autumn in the northern sector and spring in the souther one.
