Origins of the Kuroshio and Mindanao Current

The overarching goal of OKMC was to quantify patterns of flow and fluxes of mass, heat, and salt, for the ultimate purpose of establishing predictability. Spray underwater glider observations focused especially on the North Equatorial Current and the Mindanao Current.
