Abstract : This project supports the research in physical oceanography of a Ph.D. student in the MIT/WHO I Joint Program. The project benefited from, and complemented, ONR's Air-Sea Interaction Regional Initiative (ASIRI) DRI, in which the PI has been involved. There are two themes to the student's research. (1) Submesoscale processes in a freshwater influenced region- the Bay of Bengal. The vorticity, strain rate and divergence of the upper ocean circulation were analyzed through a cluster of drifters deployed from an ASIRI cruise on board the R/V Revelle. The analyses examined the impact of these processes on the dispersal of freshwater estimated from surface salinity. (2) The role of physical processes on the patchiness of biological distributions. The distribution of reactive tracers was examined in a numerical model, subject to different degrees of turbulence.
