A high-quality database that includes multi-beam bathymetry, piston core, AMS 14C dating, micropaleontologic data, was used to investigate the interactions between downand along-slope processes within the Taiwan Canyon, South China Sea Slope off southwestern Taiwan. Bulimina aculeate, Planulina wuellerstorfi and Eggerella bradyi, which are typical of indicators of the Northern Pacific deep water, were found in the core sample. And most of them occur as bio-skeletons and shell fragments, suggesting the invasion of deep water of the Pacific during the deposition. This evidence supports the assumption that there was an active bottom currents. Comprehensive analyses suggest that the sand deposits of core HD133 should be the product of interactions between gravity and bottom currents.
