Oceanographic data (Ecofer, Givapa and Gastel cruises) and satellite images evidence that the channels 1 and 2 (visible and near infra-red regions) of AVHRR/NOAA-11 can be used to estimate the total concentration of suspended sediments on the sea surface, with a daily frequency when under cloudless skies. The near infra-red channel is used for atmospheric corrections. The fit function obtained between the concentrations determined by filtration and the corrected satellite data is linear between 0-5mgl -1 and lOmgl-1. The satellite data are also compared to ship data scattering measurements. The results match.
