Subglacial geology of Halvfarryggen ice dome, Antarctia, inferred from seismic measurements

We carried out a combined vibro-explosive seismic survey on Halvfarryggen, a local ice dome south of 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 reflecti...
