The results suggest an apparent relationship between the thermal regimes in the Antarctic waters of the Indian Ocean sector and the summer monsoon activity over India, through a link of the Mascarene High southern sub-tropical high pressure zone.

A new method based on the vertical profiles of mean and variance of the differences of mean specific volume anomaly (delta x 10) for different layers of the water column for various pairs of stations is presented. The results agree well with published information for a region in the Indian Ocean.

Estimates of erosion and deposition have been made at different cross sections along the coastline with the nearshore profiles. The effectiveness of the sand pumping and hoppering into the offshore area in safeguarding the beaches has been discussed. The nearshore profile data presented in this paper indicate that the active zone for initiation of sand movement by waves and bottom currents is even beyond 14 m depth. It has been-well supported by the rapid advance and retreat of the bottom contours starting from 3 to 14 m depths off Paradip.

An attempt is made to interpret these results with reference to the chlorophyll concentrations. An existing pigment index developed for Indian waters is tested for chlorophyll retrieval and the mode best suited for low chlorophyll waters is suggested. Page(s): 99-101 1988-06-01T00:00:00Z
