State Key Laboratory of Tropical Oceanography, South China Sea Institute of Oceanology, Chinese Academy of Sciences, Guangzhou 510301, China; 2. University of Chinese Academy of Sciences, Beijing, 100049, China Abstract: A mooring system was placed at a depth of about 3300 m west of the Luzon Strait. Upper ocean current, temperature and salinity were measured at a high frequency for more than nine months. Using harmonic analysis and power spectral analysis, we discover that at the measuring site, O1 tides had a greater amplitude in spring, and K 1 tides had a greater amplitude in winter. In summer, the internal tides were relatively weak, but there were always irregular diurnal tides at our observation site. We observed near-inertial oscillations at a depth of 200~270 m after Typhoon Nanmadol passed by; they rotated clockwise and the energy was transported downward. There were 1
