In the present paper, we have carried out analysis of surface chlorophyll-a concentration in the seas around India obtained using the Indian Remote Sensing satellite IRS-P4 Ocean Colour Monitor (OCM) data. The focus was given to southwest Bay of Bengal where such studies are scanty. The study portraits the chlorophyll-a pattern during July 1999-June 2000.(More)
Tsunami is a system of ocean gravity waves formed as a result of large-scale disturbance of the sea floor that occurs in a relatively short duration of time. The Indian Ocean is likely to be affected by tsunamis generated mainly by earthquakes from the two potential source regions, the Andaman-Nicobar-Sumatra Island Arc and the Makran Subduction Zone.

Orbital stereo data is acquired by covering same area from two exposure stations in space with oblique viewing capability. It is used for generating digital elevation models (DEM) and three dimensional viewing of the terrain in a softcopy photogrammetric workstation. A good base to height ratio (B/H), usually greater than 0.5, is necessary for generation of(More)
An algorithm relating the diffuse attenuation coefficient K(490) at 490 nm wavelengths to the ratio of normalized water-leaving radiance [L wn (443)/L wn (555)] has been developed through regression analysis of radiometric profiles obtained from three oceanographic cruises conducted in the north eastern Arabian Sea and off Orissa and Andhra coast in the Bay(More)
