摘要:This work was performed in Ubatuba, Sao Paulo coast, to assess Landsat 5/TMinformation of chlorophyll concentration (Chla) studies in the, ocean. Twentyfour water sampling stations were determined and the followlng par,ameterswere sampled: chlorophyll a, yellow substance, total suspended SOllds andSecchi depth. TM digital image was previously corrected and an average ofnine pixels values of each coordinate point was obtained from TM band l, 2and 3. A linear correlation analysis between water parameters ~ndreflectance data was applied and it was observed the correlatloncoefficients between Chla and TM1, TM2, TM3, .TM1/TM2 and TM3/TM2,respectively:0.84, 0.92, 0.86, 0.?1 and 0.71. ,A model ~o estimate ~hla fromTM bands was determined by uSlng a stepwlse multlple regresslon. Theresulting model included TM2 band (R2 adjusted=0.84
