Abstract
Particulate organic carbon and particulate organic nitrogen show a dec reasing trend towards the sea. Dissolved silica and phosphorus showed an erratic variation in the Cauvery estuary. The delta C-13 shows a ma rginal 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 frac tions and possibly exist as a ferric and/or calcium phosphate.
