The mean density of ostracod population during these four months is 226, 341, 283 and 148 respectively. It is inferred that an increase in temperature, salinity and dissolved oxygen content of the bottom water is favourable for a comparative abundance of ostracod population in the study area.

A decreasing trend was observed in the ratio of the elements to chlorinity towards the off-shore regions. This may be due to fresh water influx through rivers. An increasing trend of the said ratio towards the northern part of the coast indicated comparatively higher fresh water inflow as compared to the southern part.

Dissolved silica and phosphorus showed an erratic variation in the Cauvery estuary. The delta C-13 shows a marginal conservative behaviour in the Cauvery estuary. Reduction in the dissolved P and Si concentrations are accompanied by enhanced levels in particulates. Phosphorus in sediments occurred in all the size fractions and possibly exist as a ferric and/or calcium phosphate.

This paper describes the movement of sediment plume while dredging and disposal. The study indicates that for the present disposal location, the sediment plume settles down before reaching 50 m water depth, whereas shifting the disposal location to a distance of 1000 m from the reef, would cause the sediments to settle down before 200 m water depth. The study confirms that there is no settlement of dredge spoil in the lagoon bed or on the reef.
