A dataset of supraglacial meltwater rivers in the ablation area of Sermeq Avannarleq glacier, Greenland.
Due to the increasingly dramatic global warming, surface meltwater is one of the main causes of the mass balance of Greenland Ice Sheet (GrIS). The detection and the understanding of distribution of supraglacial rivers is of great significance for the studies of glacier dynamics and mass balance. On...
