Data from five comprehensive field experiments during years 2000-2006 were used to study the internal tidal flow pattern in the Kaoping Submarine Canyon (KPSC), Taiwan. The internal tides are large with interface displacements of about 200 m and maxima velocities of over 100 cm/s. They are characterized by a first-mode velocity structure with zero crossing at about 100 m depth. In the lower layer, the currents increase with increasing depth. Vertical phase shift is apparent, especially near the canyon head. Also, the density reaches the maximum at about the end of the flood currents, indicating a predominant standing wave pattern.
