(Table 1) DSDP Site 94-609 radiocarbon dates@en

DEPTH, sediment/rock gives meters below seafloor [mbsf]. 14C dates are uncorrected for reservoir age and from Bond et al. (1993). The date at 55 cm is from Elliot et al. (1998), and does not include a reported error; we assumed a value of 100 years. Marine09 calibration is from (Reimer et al., 2009). The reported calibration ages are the rounded, median probability determined by the online version of Calib 6.0 (Stuiver and Reimer, 1993).深度：沉积物/岩石的海底以下埋深，单位为meters below seafloor（缩写mbsf）。未校正水库效应年龄的碳十四（¹⁴C）测年数据源自Bond等（1993）的研究。55 cm处的测年数据源自Elliot等（1998）的研究，未标注测定误差，我们假定其误差为100年。Marine09校准（Marine09 Calibration）方案源自Reimer等（2009）的研究。所报告的校准年龄为经Calib 6.0在线版（Stuiver与Reimer，1993）计算得到的取整中位概率值。
