He thinks the liberation of methane stored at the bottom of the ocean in structures called clathrates is the most likely culprit.

他认为出现这种现象的最可能诱因是甲烷气体的释放, 这些甲烷气体释放前存底称作" 笼形包合物" 的结中。

Clathrates are crystals, where instead of bubbles, the molecules are trapped in a cage made by the bonds between frozen water molecules.

网格是晶体，是气泡，而是被困由冰冻水之间的键制成的笼里。

That's because when you get down below 600-700 meters, the pressure is so high that the air turns into something called a clathrate which is an ice-like substance.

这是因为当你下降到 600-700 米以下时，压力非常高，以至于空气会变成一种叫做笼状物的东西，笼状物是一种类似冰的物质。

Organic matter may also be trapped in ice: on land in areas of permafrost, and at the bottom of the sea in molecular structures called clathrates.

陆地上的永久冻土地区，底被称为笼形化合物的结中。
