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
