Abstract
Activities of dissolved and particulate234Th were measured to study the spatial variation of scavenging phenomena in the surface water of the Bashi Channel and the Luzon Strait. Using an irreversible scavenging model, the residence times for total, dissolved, and particulate234Th are 28-613, 8-156, and 7-306 days, respectively. Along the PR21 transect of the WOCE project, three major domains can be identified based on the hydrography and the234Th data: the Bashi Channel, the Northern Luzon Strait, and the Southern Luzon Strait. Tight correlation between the scavenging constant and the suspended particle matter (TSM) concentration in the surface water of the Northern Luzon Strait implies that TSM concentration is an important parameter in studying thorium scavenging. © 1992 Journal of the Oceanographic Society of Japan.
