Research group: Amala Mahadevan's Lab, Ocean and Environmental Processes


Currently working on an initiative in the Bay of Bengal, Indian Ocean. Funded by the U.S. Office of Naval Research, the project is an international collaboration to better understand how the ocean affects the seasonal Monsoon rains over land, ultimately improving weather forecasts and climate projections for the region. The project involves fieldwork on research ships, deploying surface and underwater drones, analysing hydrographic, atmospheric, and satellite surface data, as well as modelling  the processes at play in the ocean-atmosphere system.
