Nioghalvfjerdsbræ 70 km+ Long Supraglacial stream, Greenland’s Longest?
Landsat image of Nioghalvfjerdsbræ in 2017 with supraglacial stream indicated by arrows and calving front yellow dots. I first observed the impressive discharge and length of the supraglacial streams working on Jakobshavn Glacier more than 30 years ago. The longest persistent supraglacial stream in Greenland at present that I am aware of is on Nioghalvfjerdsbræ (79 Glacier). The longest streams will occur on glaciers with low slopes in the ablation zone …
