             abstract = "Abstract The multispectral scanner imagery of ERST-1 allow us to 
                         compare the size, distribution and gray shade of nearshore turbid 
                         waters. The main sources of this are river effluents, eroding 
                         headlands, production of planktonic organisms and waste effluents. 
                         The changes in river discharge, intensity of surf action and 
                         direction of nearshore currents observed by mean of suspended 
                         particle as tracer, can be followed in the ERST-1 images since we 
                         have a repetitive each 18 days. The Guanabara bay and adjacents 
                         areas contain a mixture of different water masses, including the 
                         discharge of rivers. Complex surface currents patterns exist, 
                         particularly in the area outside the bay. Some evidence of 
                         pollution can be seen inside the bay. A digicolor system was used 
                         and the resulted color enhancement of MSS band 4 and 5 were 
                         analysed. Resumo As imagens do scanner multiespectral de ERST-1 
                         nos permite comparar o tamanho, distribui{\c{c}}{\~a}o e sombra
