Radiometric dates and ages of isotopic stage boundaries of sediment core GIK12392-1, off NW Africa (Table 1)

Ages of stage- and substage boundaries were adjusted according to CARPOR timescale (Herterich and Sarnthein, 1984; Sarnthein et al., 1984). Values after Thiede et al. (1982), measured on Uvigerina peregrina阶与亚阶界线的年龄依据CARPOR年代标尺（Herterich与Sarnthein，1984；Sarnthein等，1984）进行了校正。相关数值源自Thiede等（1982）的研究，基于瓷质靴形虫（Uvigerina peregrina）测定得到。
