Description This paper deals with an estimation of phytoplankton pigments from Landsat Thematic
Mapper (Tivi) data after removal of atmospheric effect. The pigments derived from Landsat TIV1 data
of October, 1986 and March, 1987 have been compared with corresponding surface values measured
during ship cruise programmes synchronous to satellite overpass. In-water algorithm for Landsat TM
bands was developed from the sea data collected off Quilon to Malpe In the Arabian sea at different
periods of the year. A uniform bias towards underestimation of pigments has been observed in the
case of October data and an appropriate modification In the pigment algorithm for Landsat TM has
bnen suggested.
