Outline of Final Research Achievements

We successfully developed a next-generation oceanic circulation modeling framework by incorporating submesoscale turbulence and interactions between waves and ambient current that have not been properly implemented before the present study. The model thus accounts for virtually all the components required to the coastal physical oceanography including buoyancy inputs, tides and surface wind stresses and has extensively been exploited to examine coastal circulation and associated material transport. During the project, we have applied the model to 1) coastal dispersal of the radionuclide leaked from the Fukushima Dai-ichi Nuclear Power Plant, 2) surfzone-inner shelf interaction in Santa Monica Bay, California, 3) coastal and pelagic larval network in the Seto Inland Sea, and 4) development of a data-assimilative eddy-resolving oceanic downscaling model in the Kuroshio region off Japan.
