In this study area, located between the subarctic and subtropical domains of the North Pacific, the confluence of the warm Kuroshio Current and the cold Oyashio
Current forms the Kuroshio-Oyashio

The heat content is indicative of the wind-driven, upper-ocean circulation with subtropical and subpolar gyres and the Kuroshio/ Oyashio
Extension current along the tight gradient between them.
This estuary is semiclosed and is connected to Akkeshi Bay (open to the Pacific Ocean-controlled cold Oyashio
