Survey Maps

Survey location on the Whiilans Ice Stream.
Magnetotelluric (MT) survey along two profiles crossing the grounding zone. MT stations (yellow triangles) where collocated with seismic imaging profiles (pink lines). Gray lines show nearby radar profiles.
MT stations (triangles) collected in an array at Subglacial Lake Whillans. The lake shape as inferred from satellite data is shown in blue. Orange triangles denote MT stations that also recorded controlled-source EM transmissions generated by a 270 x 270 m loop antenna installed next to our field camp site (red circle). Pink lines show the locations of previous seismic imaging profiles and thin gray lines show existing radar profiles.
