The profiles cover western Dronning Maud Land, south of the EDML ice core site and connect the EDML ice core site with South Pole. The data are available as netCDF files (including waveforms and metadata), KML files of the profile line locations, and quicklook images of the radargrams.Project PI: Daniel Steinhage (AWI) and Wilfried Jokat (AWI)
