(Table 6) Gas hydrate-related details of unit I and unit II deposits at the Hakon Mosby Mud Volcano

a = The extent of analytical uncertainties is discussed in section 3.4.2; pv, pore volume.
b = Assuming identical hydrate fractions in shallow and in deeper sediments.
c = Considering mean values.
d = At standard temperature and pressure (STP).

a = 分析不确定度的取值范围已于3.4.2节展开讨论；pv指代孔隙体积（pore volume）。
b = 假设浅层与深层沉积物内的水合物占比完全一致。
c = 基于平均值进行考量。
d = 在标准温度与压力（standard temperature and pressure, STP）条件下。
