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甲烷气体的释放, 这些甲烷气体释放前存储在海底称" 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.

晶体，分子不气泡，而被困在由冰冻水分子之间的键制成的子里。

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状物的东西，状物一种类似冰的物质。

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.

在陆地上的永久冻土地区，在海底被称为化合物的分子结中。
