In the IODP 372A proposal, working hypotheses used with respect to actively deforming gas hydrate‐bearing landslides were based on an initial calculation considering gas hydrate to occur in fresh water. This initial inaccuracy leads to predict the base of methane hydrate stability zone (MHSZ) to be at around 162 m below the seafloor (mbsf) at site U1517 while it is expected to be between 85 and 128 mbsf. It is most interesting that important negative chloride anomalies were measured well below the theoretical MHSZ without direct evidence of the presence of gas hydrate. These anomalies are usually a strong indication of gas hydrate occurrence. This initial inaccurate hypothesis provides the opportunity to evaluate the effectiveness of the indirect salinity detection method to quantify gas hydrate.

在IODP 372A提案中，关于主动变形含天然气水合物的滑坡所使用的工作假设是基于考虑到天然气水合物在淡水中发生的初步计算得出的。这种最初的不准确性导致预测甲烷水合物稳定区（MHSZ）的基点位于站点U1517的海底（mbsf）下方约162 m，而预计在85至128 mbsf之间。最有趣的是，重要的负氯离子异常的测量值远低于理论MHSZ，而没有直接证据表明存在天然气水合物。这些异常通常是天然气水合物发生的强烈指示。最初的不正确假设为评估间接盐度检测方法量化天然气水合物的有效性提供了机会。
