TitleUse of ERTS-1 images in coastal studies in Guanabara bay and adjacents waters
CitySao Jose dos Campos
KeywordsGuanabara, adjacent, Guanabara, adjacente.
AbstractAbstract 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, distribuição e sombra cinza de águas turvas nearshore. As principais fontes deste são efluentes do rio, promontórios erosão, a produção de organismos planctônicos e efluentes de resíduos. As mudanças na vazão do rio, a intensidade da ação de surf e direção das correntes nearshore observados por meio de partículas suspensas como traçador, pode ser seguido nos ERST-1 imagens uma vez que temos um repetitivo cada 18 dias. Baía de Guanabara e áreas adjacentes a estas contêm uma mistura de diferentes massas de água, incluindo a descarga de rios. Existem complexas correntes de superfície padrões, particularmente na área fora da baía. Algumas evidências de poluição pode ser visto dentro da baía. Um sistema digicolor foi usada eo realce da cor resultaram de MSS banda 4 e 5 foram analisados.
