根据南海8个站位浮游有孔虫δ13C的汇总,得出近20万年来的综合曲线,经过对比发现其变化与太平洋和大西洋的浮游有孔虫δ13C变化的规律一致,均显示出偏心率长周期和岁差周期的变化,而三次δ13C最低值均发生在冰消期．可见大洋碳储库在冰期旋回中的变化,不仅是对于冰盖消长的响应,同时又直接受低纬过程(如季风)的驱动． According to the summary of the δ13C planktonic foraminifera at 8 stations in the South China Sea, a comprehensive curve was obtained over the past 200,000 years. The changes were consistent with the δ13C changes of planktonic foraminifera in the Pacific and Atlantic Oceans. All of them showed a long eccentricity Cycle and precession cycle changes, while the three lowest δ13C occurred in the ice extinction. It can be seen that the change of the oceanic carbon reservoir in the glacial cycle is not only the response to the ice cap growth but also directly driven by the low latitude (such as the monsoon).
