Antarctica's secret water network found

摘要

The first complete map of the lakes beneath Antarctica's ice sheets reveals the continent's secret water network is far more dynamic than we thought. This could be acting as a powerful lubricant beneath glaciers, contributing to sea level rise.rnUnlike previous lake maps, which are confined to small regions, Ian joughin at the University of Washington in Seattle and colleagues mapped 124 subglacial lakes across Antarctica using lasers on NASA's ICESat satellite (see map).rnThe team also observed the lakes draining and filling.
