A glaciologist rather than a biologist, he wanted to investigate a question critical to climate change: Do subglacial rivers and lakes lubricate the movement of ice over land — and might they somehow accelerate a glacier's flow into the ocean, triggering rapid sea level rise?

What's left to figure out is whether this is happening with other subglacial lakes around the Greenland ice sheet, as well as whether and how to incorporate the findings into models that are aimed at gauging how much Greenland might change with the warming climate and how much water it could add to the rising seas.

Researchers with the British Antarctic Survey have been planning for 16 years to drill a borehole into the ice atop this subglacial lake, a hole that will freeze back over within 24 hours.

Channels can also be incised into the bedrock or subglacial sediments (Nye channels).

Methanogens are common on Earth in places devoid of oxygen, such as in the rumens of cows, and could easily have been scraped up by ice flowing over the swampy subglacial soil and incorporated into some of the bottom layers of ice.
