Abstract The chemical analysis of the marine water samples was used along with IRS-P4 (OCM) data to prepare chlorophyll concentration maps for the Thane creek, Mumbai, India. The chlorophyll a +phaeopigment ([C+P]) retrieval was done using a bio-optical algorithm, which was applied to detect the concentration from Ocean Colour Monitor data. Marine water samples were collected on March 15, 2001, March 21, 2001, March 23, 2001 and March 25, 2001 synchronised with the IRS-P4 satellite overpass. Standard methods were used to chemically analyse the samples. The Chlorophyll distribution map from OCM data was prepared using Erdas Imagine 8.4 and SeaDas 4.0. The result
