Atmospheric CO2 and Air-Sea exchange

I work with atmospheric CO2 and its exchanges between the atmosphere and the ocean under the guidance of Prof. Jayanarayanan Kuttippurath at the Centre for Ocean, Rivers, Atmosphere, and Land Sciences (CORAL), Indian Institute of Technology Kharagpur.

As part of the project O-MASCOT sponsored by INCOIS Hyderabad, we deal with the customization of an ocean-atmosphere coupled model to study the nutrient exchanges between the atmosphere and the ocean. The ocean is the largest carbon sink, and literature estimates about 40% of the carbon get stored in the oceans since industrialization.

My research concentrates on the increasing trend of CO2 in the atmosphere and its impact on the marine ecosystem, especially in the Indian Ocean, analyzed using satellite measurements and numerical models.


• Development of an ocean-atmosphere coupled model.
• Study on the impact of atmospheric pollution/aerosol on the biogeochemistry of Bay of Bengal.
• Study on the impact of atmospheric deposition in the Bay of Bengal on regional Climate.


• The changing behaviour of the ocean in absorbing and releasing carbon affects the marine environment. The physical and chemical changes of the seawater resulting from unbalanced carbon exchanges will have a drastic effect on flora and fauna.
