Indian Aquatic Ecosystems: Impact of Deoxygenation, Eutrophication and Acidification (Project No. PSC0108)
To understand processes responsible for formation of oxygen minimum zones in the North Indian Ocean and to evaluate the extent of ongoing changes in oxygen
distribution in the region through observations and modeling.
To establish trends in changes in seawater pH in the North Indian Ocean and evaluate the impact of acidification on biogeochemistry and ecosystems.
To understand the fate of fertilizers, especially nitrogen, in terrestrial ecosystems in order to evaluate their fluxes to the ocean and consequent modification of coastal
biogeochemistry and ecology.
To improve the understanding of OMZ processes such as redox transformations of biogenic elements and their interactions, microbial ecology, trophic transfers in lowoxygen waters, and effect of oxygen deficiency on benthic processes, and to evaluate the current and future impacts of human activities on these processes.
To reconstruct paleo-redox conditions from sedimentary record from the Indian continental margin.
