Abstract

A stacked ocean carbon isotope (δ 13C) record of 200 ka is established on the basis of planktonic foraminifer (Globigerinoides ruber) δ 13C data from 8 sites in the South China Sea (SCS). The δ 13C record from the SCS displays a trend similar to that from the Pacific and Atlantic oceans mainly responding to long eccentricity and precession cycles, with all the three δ 13C minima occurring at glacial terminations. Thus, the changes of the oceanic carbon reservoir in glacial cycles should not be considered as a response only to ice-sheet variations, but could have been driven also by low latitude processes, such as the monsoon.
