(Table 3) Residual hydrocarbon gas concentrations at ODP Sites 164-994, 164-9...

Sediment depth is given in mbsf. Concentrations given per liter wet sediment. 0.0 = concentrations are below the detection limits of the method.沉积物深度以海底以下米（meters below seafloor, mbsf）为单位给出。浓度以每升湿沉积物为基准进行计量。当浓度为0.0时，表示该数值低于对应分析方法的检测限。
