• The Kuroshio
• ADCP measurement
• ocean-current power generation
• site selection
• Miyake Island

To discover sites suitable for ocean-current power generation, we conducted a site selection by analyzing JCOPE2 reanalysis data. Miyake Island was chosen for further consideration, and Acoustic Doppler Current Profiler (ADCP) measurements were conducted from August 31 to September 2, 2010. The measured horizontal and vertical velocity profiles revealed convergence of currents through a narrow passage between Miyake Island and a smaller island to the west. Such fine-scale structures of the current field can only be detected through in-situ measurement. Therefore, we concluded that not only reanalysis data but also in-situ observation and regional ocean modeling are crucial for feasibility study of ocean-current power generation.
