Supraglacial lake evolution on the Greenland Ice Sheet ...
Abstract. Supraglacial lakes form annually on the surface of the Greenland Ice Sheet around Paakitsoq, north of the Jakobshavn Isbrae outlet glacier. The lakes are ephemeral, drain through moulins or crevasses at their bed throughout the melt season, and deliver large volumes of water to the subglac...
