Description Preliminary results obtained form pilot experiments in Godavari estuary, Andhra Pradesh, India to understand the ecosystem and biogeochemical processes have been presented. During the southwest monsoon the estuary can be, even when the discharge is humanly controlled, flushed in less than a day. During the peak discharge periods nutrient concentrations in river waters are high but found to decrease downstream. The estuary becomes heterotrophic during the monsoon that slowly shifts to autotrophic in the following dry seasons. Biological productivity was found to be very high during the retrieval period of the monsoon. These initial results suggest that the Godavari estuary ecosystem is different from what we know of its seasonal variability.
