(Table 1) Age model of ODP Site 162-983

The age model was constructed by correlation of 27 tiepoints between the oxygen isotopic record of Site 983 and a reference signal derived by combining the record of SU90-08 (Vidal et al., 1997 doi:10.1016/S0012-821X(96)00192-6) from 0 to 130 ka with the SPECMAP record of Martinson et al. (1987 doi:10.1016/0033-5894(87)90046-9) for 130 to 350 ka.本年代模型通过27个定年锚点的对比构建而成：将983站位的氧同位素记录与由两套分时段记录整合得到的参考信号进行匹配。其中0~130 ka时段的参考信号由SU90-08岩芯（Vidal等，1997，DOI:10.1016/S0012-821X(96)00192-6）的记录整合得到，130~350 ka时段的参考信号则采用Martinson等（1987，DOI:10.1016/0033-5894(87)90046-9）的SPECMAP记录。
