This work searches to identify the possibility to use orbital remote sensing in the monitoring of water quality in Lagoa da Conceição, Florianópolis, SC, specifically regarding levels of Chlorophyll_a and its implications in water color, a property which can be evaluated through satelite imagery. The aim of his study was to obtain a correlation between the levels of Chlorophylla_a found in water samples from Lagoa da Conceição and the spectral response pattern detected by sensors built into the commercial satellite TM5. The results show that orbital systems like Landsat TM5 can be utilized in the investigation of water quality parameters that effect surface color in bodies of water. Through satellite imagery it is possible to obtain the spatial distribution of concentrated substances such as Chlorophyll_a.
