PS44D:
The Roles of the Indonesian Mix-Master, Including Contributions from Adjacent Seas I Posters

Session ID#: 85219

Session Description:
The Indonesian seas are called the Indonesian Mix-Master for their role in transforming North and South Pacific waters into cooler, fresher Indonesian Throughflow (ITF) water, the outflow of which affects the dynamics of the Indian Ocean. This mixing has been primarily attributed to strong internal tides, with huge tidal energy converted into diapycnal mixing through topographic interactions. The topography of the Indonesian archipelago is extremely complex and characterized by deep basins separated by shallow sills and rough ridges/spurs. Adjacent seas, including the South China Sea, Andaman Sea, etc., also have strong internal tides and enhanced tidal mixing, and contribute to the water transformation. This session aims to explore issues related to internal tides and tidal mixing in the Indonesia Seas and the adjacent seas, including observations, simulations and estimation. Specifically, we welcome abstracts concerning (but not limited to) the following topics in relation to the Indonesian seas and/or the adjacent seas: 1) direct/indirect observations of internal tides and/or tidal mixing; 2) internal tidal simulations and their sensitivity to the horizontal/vertical resolution, open boundary conditions, treatment (smoothing) of topography, etc.; 3) internal tidal features, regarding generation, propagation, and/or dissipation; 4) barotropic and baroclinic energy budget analysis; 5) estimation of tidal dissipation and mixing; 6) impacts of tidal mixing on the stratification, water mass transformation/ transportation, circulations (especially the ITF), nutrient distribution, biogeochemical processes, regional climate, etc., in the Indonesia Seas and adjacent regions.
