Description:
We carried out a combined vibro-explosive seismic survey on Halvfarryggen, a local ice dome south of the German
research station Neumayer III. The Vibroseis survey was grid shaped to provide spatial information about the
glaciological and geological substructure. The center survey line was also surveyed with explosive reflection and refraction seismic set-ups. The ice bed contact we interpret as a frozen till layer overlaying bedrock. From velocity analysis of refractions seen in far offset data, we obtain a pressure-wave velocity 〉5000 m/s. We therefore interpret the bedrock as igneous, which supplements previous magnetic and gravimetric data sets.
