A dataset of supraglacial meltwater rivers in the ablation area of Sermeq Avannarleq glacier, Greenland.
Listed in ScienceDB
Due to the increasingly dramatic global warming, surface meltwater is one of the main causes of the mass balance of Greenland Ice Sheet (GrIS).
Description
The detection and the understanding of distribution of supraglacial rivers is of great significance for the studies of glacier dynamics and mass balance. On 24 and 27 October 2021, based on a drone equipped with an RGB sensor, we survey the ablation area of Sermeq Avannarleq Glacier on the northeast of Jakobshavn, and obtained high-resolution orthophoto images of the nearly 40km2 area of the glacier.
Based on these images, the supraglacial rivers were visually interpreted and delineated. This dataset contains 8643 pairs of 256×256 pixels size orthophoto crops and labels.
