Implementação de Algoritmos Bio-Ópticos Regionais a partir de Medidas Radiométricas Coletadas In Situ : Baía de Guanabara (RJ)

Abstract

Considering the environmental, economic and social importance of Guanabara Bay, located in Rio de Janeiro (RJ), the main objective of this case study is to elaborate regional empirical algorithms for the monitoring of phytoplankton concentrations present in this estuarine region. This may aid in the lack of pollution monitoring in this area. With the great spatial and temporal variability caused by the circulation pattern in the Guanabara Bay, many accurate sampling points were arranged for an adequate water quality analysis. The radiometric data collected in situ, processed and adjusted allowed the elaboration of these bio-optical algorithms, through the observation of a band that presented spectral signatures associated with the intense flowering of phytoplankton and the high concentration of dissolved organic matter.
