Outline
A submarine mooring system was deployed in the east of the Luzon Strait and the vertical distribution of high frequency (mostly tidal) variations of ocean currents were analyzed in the paper. Several features were revealed that the tidal kinetic energy of the middle (1 550 m) and the deep layers（2 560 m） was one to two orders smaller than that of the subsurface layers (100−160 m) , and slightly smaller than that of the near-bottom layers (4 040 m); the tidal currents were irregular semi-diurnal in the subsurface layers and were irregular diurnal in the middle and deep layers; the tidal kinetic energy was larger in summer (June to September) and winter (February to March) , which mainly caused by enhancement of M2 and K1 tidal components in corresponding periods; the high frequency fluctuations in all layers were mainly in clockwise rotation; the near-inertial frequency in the upper layers (middle and deep layers) were close to (slightly smaller than) the local inertial frequency.
