(Table 5) Inter and intra laboratory Pb isotope duplicates of authigenic Fe-M...

Sediment depth is given in mbsf. All inter and intra laboratory comparison data are normalized to NIST SRM 981 values reported in Galer and Abouchami (1998) for comparison to...沉积物深度以mbsf（meters below sea floor，海底以下米）为单位。所有实验室间与实验室内的比对数据均已归一化至Galer与Abouchami（1998）报道的NIST SRM 981（美国国家标准与技术研究院标准参考物质981）数值，以用于与……进行比对。
