Abstract

On the basis of the cruising data of Lowered Acoustic Doppler Current Profilers (LADCP) and ship-mounted ADCP (SADCP) and so forth, during the cruise of Luzon Strait in April 2008, velocity profile is figured out using the LDEO LADCP processing software. We take use of the simulating results of TPXO7.2 (a TOPEX/POSEIDON global tidal model) to remove the tidal current speed from the measured value. The following main results have been obtained: the core of intruding Kuroshio flows through station C2, C7, C8 and C9, respectively, and the positions of core agree basically with those in spring 1992. At station C2 the Kuroshio is located in the upper layer from sea surface to 400 m with the maximum westward speed 77 cm/s, and its speed decreases with the increase of water depths. At station C7, C8, C9, the Kuroshio is located in the layer from surface to 500 m, depth of the Kuroshio becomes shallow gradually when it intrudes into the South China Sea. The observation results may be a support to the sandwiched vertical structure of Luzon Strait transport.
