我们记录的密度和水文特性的裸露，消融冰中海拔（1215米a.s.l.）。格陵兰西部冰盖Kangerlussuaq地区的冰上内部排水集水区。我们发现低密度（0.43-0.91 g cm（-3），mu = 0.69 g cm（-3））冰到冰盖表面以下至少1.1 m的深度。这种近地表的低密度冰由水饱和的多孔冰和透明的固体冰透镜体交替层组成，上面覆盖着一层薄薄的（
We document the density and hydrologic properties of bare, ablating ice in a mid-elevation (1215 m a.s.l.) supraglacial internally drained catchment in the Kangerlussuaq sector of the western Greenland ice sheet. We find low-density (0.43-0.91 g cm(-3), mu = 0.69 g cm(-3)) ice to at least 1.1 m depth below the ice sheet surface. This near-surface, low-density ice consists of alternating layers of water-saturated, porous ice and clear solid ice lenses, overlain by a thin (
