3D radar topography, radar-derived bed reflectivity and seismic acoustic impedance of Rutford Ice Stream, West Antarctica, December 2005 to January 2017

The 3D migrated radar data shows more details of the bed topography compared to the 2D migrated data. Even though most parts of the bed show a clear reflection, the steep flanks and parts of the steep stoss end of the Bump lack a clear return in the 3D migrated data. Similarly, the bed reflection along the stoss end of the Bump is not identifiable in the seismic line. Missing values in the data are presented as #NV.
