(Table S3) Mean sea surface temperture values of the Eocene-Oligocene Transition at individual DSDP and ODP sites

Estimated values at ~33-34 Ma (EOT) and at ~34-37 Ma (pre-EOT). With consideration of chronology uncertainty, we allowed time intervals over which mean SST values were calculated to vary slightly (up to 0.5 Ma). The mid-point and length of time intervals used for calculation are indicated by the column \"Age (Ma)\". For instance, 33.4±0.3 indicates a mid-point of 33.4 Ma and an interval of 33.1-33.7 Ma.估算值分别取自约33~34 Ma（始新世末期，End of Eocene，EOT）和约34~37 Ma（始新世末期前，pre-EOT）。考虑到年代学的不确定性，我们允许计算平均海表温度（Sea Surface Temperature，SST）所使用的时间区间存在小幅波动，最大波动幅度可达0.5 Ma。本次计算所用时间区间的中点与时长，由"Age (Ma)"列标注。例如，"33.4±0.3"表示该时间区间的中点为33.4 Ma，区间范围为33.1~33.7 Ma。
