| Abstract: | Indian Remote Sensing Satellite (IRS) — P4 Ocean Colour Monitor (OCM) data were used to estimate Suspended Sediment Concentration
(SSC) in the coastal waters off Chennai and to study the distribution along the coast. Surface water samples were collected
during May and October 2000 synchronized with satellite overpass, and quantitative estimates of Suspended Sediment Concentration
(SSC) were done. OCM — Data Analysis System (DAS) software developed by the Space Applications Centre, Ahmedabad was used
for OCM data processing and analysis. The field data and OCM derived SSC showed a correlation of r = 0.85 and r = 0.95 for
the months of May and October respectively. |
