Description 15-17
Interrelationship between the apparent oxygen utilization and changes of nitrate-nitrogen and phosphate-phosphorus in the Western Bay of Bengal has been studied using the data collected during the cruises of RV Gaveshani from August to September 1976. The atomic ratios obtained are: ∆ AOU: ∆ N: ∆ P = 260:12.4:1. Nitrate values show deficit ranging from 30 to 40% in the depth range 100-800 m. This is in conformity with the earlier work and suggests that denitrification takes place in this region at intermediate depths. The reserved fraction of dissolved phosphorus (Pr), in association with
t is used for the classification of various water masses in the south-western Bay of Bengal. The various waters thus classified are (i) Indian Equatorial Water lying below 150-200 m; (ii) A mixture of Persian Gulf and Red Sea waters lying between 350 and 550 m and having low Pr; and (iii) North Indian Deep water lying below 1000 m characterized by high Pr and oxygen.
