Carter, Charlotte; Franke, Steven; Helm, Veit; Jansen, Daniela; Paden, John D; Eisen, Olaf: High-resolution Digital Elevation Model of subglacial topography in the onset region of the Northeast Greenland Ice Stream, generated from swath radar imaging [dataset]. PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.972422 (dataset in review)
Abstract:
Rapidly-flowing ice streams drain the interior of the Greenland Ice Sheet, currently accounting for half of its annual mass loss. The Northeast Greenland Ice Stream (NEGIS) is one of the longest, recognisable almost 600 km inland, extending close to the ice divide. Here, we use swath radar imaging to create a high-resolution Digital Elevation Model (DEM) of the bed under the onset zone of the NEGIS, from radio-echo sounding data collected in 2022. The DEM covers a 40 km by 60 km area centred on the drill site for the East Greenland Ice-core Project (EGRIP). It has a spatial resolution of 25 m in coordinate system WGS 84 NSIDC Sea Ice Polar Stereographic North (EPSG 3413). The acquisition system was a multichannel ultra-wideband radar mounted on AWI's POLAR 5 aircraft.
