Physical Oceanography Section
We investigate the structure and variability of the Mixed Water Region, in particular the Kuroshio Extension, the Oyashio, Tsugaru Warm Current and warm core rings which are closely related to the formation of fishing grounds and production of prey plankton in the Mixed Water Region. At the same time, long-term variability which is associated with climate change and considered to be closely related to resource variability is being investigated in co-operation with Japanese and foreign institutions. On the basis of these studies, we produce forecasts of ocean conditions of the Mixed Water Region to be utilized by fisheries.
