Boundary scavenging in the Pacific Ocean - A comparison of Be-10 and Pa-231

摘要: Measurements of U, Th, Pa-231, and Be-10 concentrations were conducted in Holocene sediments from several sites representing open-ocean ocean-margin environments the Pacific Ocean. The results show that boundary scavenging plays a major role removal Pacific. Deposition is more than an order magnitude greater at margin deep central sites, while Pa-231 4- to 5-fold sites. factors controling Pa Be are discussed.
