Rapid basal melting of the Greenland Ice Sheet from surface meltwater drainage [Earth, Atmospheric, and Planetary Sciences]

Subglacial hydrologic systems regulate ice sheet flow, causing acceleration or deceleration, depending on hydraulic efficiency and the rate at which surface meltwater is delivered to the bed. Because these systems are rarely observed, ice sheet basal drainage represents a poorly integrated and uncertain component of models used to predict sea...
