Extreme melt season ice layers reduce firn permeability across Greenland

The long-term impact of extreme surface melt on the Greenland Ice Sheet is poorly constrained. Here the authors use airborne radar to characterize a subsurface refrozen melt layer that formed following extreme melt in 2012, showing that it likely reduced drainage pathways for subsequent melt.
