Utilización de datos satelitarios en investigaciones oceanográficas y pesqueras en el océano Atlántico sudoccidental
The use of satellite data in oceanographic and fishery studies in the SW Atlantic is reviewed. First, terms commonly used in the remote sensing literature are defined. The main satellite sensors used in oceanographic applications are described, and the principles of the remote estimation of two important variables, sea surface temperature(SST)and ocean color, are discussed. The use of remotely sensed data in oceanographic studies of the SW Atlantic is reviewed. Most studies are based on satellite SST fields and describe circulation in the open, particularly near the confluence of the Brazil and Malvinas currents. Due to the limited number of fishery studies based on satellite data in the SW Atlantic, examples from other parts of the world are reviewed. Future perspectives for satellite oceanography studies in the SW Atlantic are discussed.
