(Table 2) Residual hydrocarbon gas concentrations at ODP Sites 164-991, 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。浓度以每升湿沉积物为计量单位。浓度值为0.0时，表示其含量低于本检测方法的检出限。
