Ocean current near Miyake Island was measured by an Acoustic Doppler Current Profiler equipped on a moored buoy system from March 2013 to March 2014 for an ocean current energy converter development project. Current variations associated with the Kuroshio,tide and wind,were found in the observed record and are described in the paper.Based on the Kuroshio axis location,periods with and without the Kuroshio intrusion into the island were identified. Spectral analysis of the current speed revealed that the diurnal variation is enhanced when the Kuroshio does not intrude.This enhancement of diurnal current variation is possibly related to the generation of the Island-Trapped Waves.By combining the fine-scale observation data and the long-term coarse-resolution Kuroshio axis data,inter-annual variability of the current power was estimated.The estimated current power is about three times larger than the one estimated from an ocean reanalysis.The result implies that coarse-resolution non-tidal numerical models possibly underestimate current power in coastal ocean.
