An evaluation of physical and biogeochemical processes regulating the oxygen minimum zone in the water column of the Bay of Bengal
(American Geophysical Union, 2002)Monthly oxygen budgets for the intermediate waters (100-1000 m) of the Bay of Bengal were constructed based on Modular Ocean Model (MOM) and oxygen data. The model results reveal that the oxygen levels in the oxygen minimum ... -
Control and interannual variability of dimethyl sulfide in the Indian Ocean
(American Geophysical Union, 2002)Aqueous dimethyl sulfide (DMS) concentrations and its sea-to-air fluxes were studied in upper layers (200 m) of the Indian Ocean, as a part of the Indian Ocean Experiment (INDOEX) that centered around the movement of the ... -
Biodiversity, zoogeography and affinity of Orissa sponges
(Allied Publishers; New Delhi (India), 2002)In the biology of the sea, the sea floor plays just as important as the open waters in the euphotic regions. Similar substrates in different areas may have quite different associations. Coral communities are immensely ... -
