subglacial

“It underscores the importance of subglacial methanogenesis,” Skidmore said..他表示：“这一发现凸显了冰川下产甲烷菌的重要性。”

They discovered that during the same 14-month period that 1.7 cubic km of water cascaded through subglacial waterways, the 75-km long glacier downstream pick up speed, moving about 10 percent faster..通过比较，研究人员发现，在14个月的时间中，冰层下湖泊溢出了1.7立方千米的水，75公里长的伯德冰川的移动速度加快了10%。

How a wave could have reached such a height remains speculative, but scientists studying the aftermath observed that a subglacial lake behind Lituya Glacier had dropped 100 feet in depth..波浪达到如此之高的机理尚在思考中，而进行灾后研究的科学工作者观测到在Lituya冰河后面，一个冰下湖下沉了100英尺。
