Ice surface elevation and ice thickness at 79°N Glacier, Greenland from airborne measurements in July 2021

We conducted airborne laser scanner and airborne radar measurements at the 79°N Glacier (Nioghalvfjerdsbræ) in Northeast Greenland in July 2021. Here, we provide ice surface elevation and ice thickness maps of the grounding line area based on 12 across-ice flow sections separated by 1 to 2.5 km. For ice thickness determination, we used AWI's Ultra-wideband (UWB, MCoRDS 5) airborne radar. The ice thickness was derived from the two-way travel time difference between the surface and the basal reflection, transformed to a thickness using a propagation velocity for the electromagnetic wave of 168.914 m μs⁻¹. The surface elevation and ice thickness were interpolated along flowlines of the ice and gridded to a regular grid with 25 m spacing. This dataset provides the latest ice geometry of the rapidly changing ice thickness at the grounding line of 79°N Glacier. The airborne data were acquired as part of AWI's 79NG-EC campaign with AWI's polar aircraft Polar5.
