(Table 1) Age determination of sediment core PS2561-2

AMS dates were obtained from monospecic samples of planktonic foraminifer Globigerina bulloides of core PS2561-2. Correction is based on the South Atlantic surface water...AMS测年（Accelerator Mass Spectrometry）数据取自岩心PS2561-2中浮游有孔虫球室抱球虫（Globigerina bulloides）的单种样品，测年校正以南大西洋表层海水……为基准开展。
