Abstract:
This dataset contains airborne radar data acquired using the AWI EMR system during the Antarctic season of 2001/02. The profiles extend across the western Dronning Maud Land along the grounding line of the Jutulstraumen Glacier, and over the EDML ice core site. The data are available as netCDF files (including waveforms and metadata), KML files of the profile line locations, and quicklook images of the radargrams.
