Description 10-14
Nitrification process was investigated in the tropical Vellar Estuary, by in situ experiments. Variation in nitrifying capacity in both estuarine and sea water was measured. Biological potential of estuarine water in the nitrification was greater than that of neritic water. Oxidation of ammonia to nitrate occurred without accumulation of nitrite. Marine nitrifiers (both ammonium oxidizers and nitrite oxidizers) were active in the photic zone of the coastal waters. In situ experiments revealed that nitrate reduction and ammonia oxidation were significant processes in the estuarine and coastal waters. Ammonia production, nitrite formation and nitrite oxidation took place simultaneously. At lower temperatures, decomposition was not retarded as much as the mineralization and hence dissolved organic nitrogen accumulated. Seasonal variations were also found in some of the biological processes. Concentration and distribution of nitrite (a transitory product formed from ammonia and nitrate) were influenced both by physical and biological processes.
