Atypical behaviour of dissolved silicate in the Cochin backwater and Periyar river
Dissolved silicate was determined for 1 y (1982-83) covering a wide range of salinity from the estuarine mouth to the fresh water region. Silicate concentration ranged between 0.03 and 4.75 mgl/1. Silicate-salinity ...
Estuarine characteristics of the lower reaches of the River Periyar (Cochin backwater)
Lower reaches of river Periyar were studied to assess longitudinal extent of salt water intrusion into the system during different seasons and also its effect on the flushing of pollutants introduced by the industries. ...
Nutrients of the Cochin backwater in relation to environmental characteristics
The nutrient distribution of the Cochin Backwater was studied at 6 stations throughout the year The depth profiles of phosphorus (inorganic and organic), nitrogen (nitrate and nitrite) and silicon, showed a marked seasonal ...
Variations of dissolved oxygen in Mandovi and Zuari estuaries
During non-monsoon months the estuaries were well mixed showing uniform oxygen concentrations from surface to bottom. However, during monsoon months both the estuaries showed stratified conditions with surface water showing ...
Distribution of nutrients in the coastal and estuarine waters of Goa
(Indian Association for Limnology and Oceanography, 1987)
Concentrations of nitrate and phosphate in the coastal waters of Goa varied from 0 to 2.4 mu g at 1-1 and from 0.1 to 2.4 mu g at 1-1 respectively, during post and premonsoon periods. In the estuarine region the nutrients ...
