The ocean covers over 70% of the earth' surface and plays a central role in the global climate change by means of great capacity to store and transport heat and materials.
This program conducts observational research based on land-to-land hydrographic observations with high accuracy in order to clarify basin scale heat, fresh water and material transport by the ocean general circulation and its variability.
We also carry out observations of water properties and velocity of the Kuroshio and the Kuroshio Extension to investigate the influences of the variability of the current path and the mass and heat transport of the currents on the distribution of heat and materials in the North Pacific Ocean.
