PO51D:
From Monsoons to Mixing: Coupled Ocean-Atmosphere Processes and Biogeochemical Response in the Indian Ocean III


Session ID#: 11482

Session Description:
The Indian Ocean is a unique semi-enclosed ocean basin whose dynamics are forced by and coupled to the summer and winter South Asian Monsoons. The feedback between the ocean and atmosphere influences regional to global weather patterns and biological productivity, often with major societal impact. This session aims to synthesize our understanding of the role of the oceans on the South Asian Monsoons through observations, modeling, and theory. Topics of interest include upper ocean processes, air-sea interaction, boundary currents, planetary waves, freshwater dispersal, and mixing. We encourage presentations that characterize the upper ocean structure and identify key processes that set the lateral and vertical temperature-salinity distribution over a range of length and time scales. We also encourage presentations on how all of these physical processes impact bio-optical, biogeochemical and ecological responses, including fisheries and humans.
