Pre-Bomb marine reservoir ages in the Western Pacific

Abstract

In this study, molluscan shells housed at the University Museum, the University of Tokyo, provided a new set of region-specific correction values (ΔR) for the western Pacific, in particular for the central part of the main islands in the Japanese Archipelago and the southwest islands of Japan. The values of 40 total samples were calculated from 11 regions. North of the main islands and in the Ryukyu Islands, the mean ΔR values showed comparatively small values, 5-40 14C Central part of the main islands, these values were 60-90 14C yr. © 2010 by the Arizona Board of Regents on behalf of the University of Arizona.
