A gas hydrate (methane clathrate) block embedded in the sediment of hydrate ridge, off Oregon, USA. Click to enlarge this image.
一块气体水合物（甲烷格状物）嵌入在水合物脊沉淀物中，位于美国俄勒冈州沿海。
If the sediment underlying a hydrate entraps natural gas, its acoustic velocity will become much lower, resulting in vivid characteristics of reflections.
若水合物下方的沉积物捕集了天然气，其声速会更低，由此产生的反射波具有鲜明的特点。
Besides temperature and pressure, the controlling factors for gas hydrate stability also include pore water composition, gas concentration in the fluid and Marine sediment types in the seafloor.
海洋天然气水合物的生成除了受温度和压力的影响外，还要受到孔隙水的化学组成、流体中气体的浓度及沉积物类型的影响。
