这个地区主要是由茂密的西伯利亚针叶林带和泥炭沼泽构成；针叶林带的树木以细长的桦木、雪松与松树为主，泥炭沼泽一年大多呈冰封状态，有些地点还会冒出甲烷。

From this perspective, flammable ice can be regarded as the natural gas in the highest purity, and you know, the general state of the natural gas, methane is only about 92% less, in addition to about 3% of the ethane, about 2% of the nitrogen and about 1% of the propane, as well as a very small amount of butane, pentane and oxygen and so on.

从这个角度说，可燃冰可算是自然中纯度最高的天然气了，要知道，一般状态下的天然气中，甲烷大约只占92%不到，此外还有3%左右的乙烷、2%左右的氮气和1%左右的丙烷，以及极少量的丁烷、戊烷和氧气等。

And it seems that methane was likely to stay in the permafrost that's under the seafloor.

看来甲烷气体可能保存在海底冻土层中，但实际上并不是这样。
