The overall goal of my work is to assist in the development of hydrodynamic and ecosystem models for Japanese coasts to support the investigation of various phenomena, particularly those that may negatively affect ecosystem health and resilience as well as human livelihood. My recent focus has been on the proper modelling of ocean and coastal acidification in order to accurately evaluate their impacts on marine calcifying organisms, in particular abalone and oysters, whose fisheries are a main part of peoples' livelihood in most of my study areas. My main research tools have been ROMS-based modeling platforms, especially CROCO, COAWST, and Rutgers-ROMS, to run both hydrodynamic as well as biogeochemical models. In combination with monitoring efforts which provide invaluable time-series data for various physical and biogeochemical parameters, model performance in terms of simulating present day coastal conditions can be evaluated. A main challenge in our study sites is properly incorporating into numerical simulations the effects of terrestrial inputs into the coastal areas, for which the necessary data is sometimes unavailable and hence requires more careful consideration. Furthermore, using a combination of carefully selected global or regional future prediction datasets, the extra step of making future projections for our study sites may also be performed. As part of my research plan, I hope to also be able to assist in the deployment, maintenance, and data analysis of coastal monitoring platforms. Although my main work is on modeling, I believe that helpful insights may also be gained by experiencing firsthand the conditions in our various study sites. Although they are not part of my main research themes at the present time, I continue to maintain an interest in topics I had previously investigated. These include particle tracking and larval dispersal simulations to investigate marine connectivity in a coastal area, and the monitoring and simulation of typhoon passages in coral reefs and other areas through the use of coupled hydrodynamic and wave models.
