Research Field

Physical Oceanography, Global Ocean Circulation in particular that in the Southern Ocean

Current Research

Past and present
(1) Interaction of marginal and pelagic oceans
Exchange between the Sea of Okhotsk and the North Pacific, tidal flows on the Australian North West Shelf and eddies offshore -- these were some of my interest.
(2) General circulation in the Southern Ocean
Ship-based data, temperature/salinity/velocity from Argo floats, and sea surface height observed by satellite altimeter -- by combining these data, I look into the circulation and mixing in the Southern Ocean.
(3) Role of mixing in the basin scale circulation
I have attempted to quantitatively understand this aspect of ocean circulation using observation data.
Present and Future
I am interested in turbulence and mixing, also internal wave dynamics behind them. Isopycnal mixing is also important and fascinating.
