Outline of Final Research Achievements

Using results of a low-trophic biogeochemical model, we calculated annually averaged horizontal nutrients transport between the Kuroshio main stream and its two lateral sides and annually averaged vertical nutrients transport through the bottom of eutrophic layer within the Kuroshio main stream. Our calculation shows 1) a large horizontal nutrients transport from inshore area south of Japan to the Kuroshio main stream; 2) a horizontal nutrients transport from mixed area to the Kuroshio Extension and a further southward nutrients transport from the Kuroshio Extension to subtropical area; 3) a large vertical nutrients transport around the Luzon Strait and Kuroshio Extension.
