Ground-Penetrating Radar Investigation of the Proposed Dome- CARA Tunnel Route and Utilities at South Pole Station, Antarctica
Ground-penetrating radar studies were performed at South Pole Station, Antarctica, during January 1993 to determine if subsurface obstructions exist along a planned tunnel route from the main station to the new astrophysical research area on the far side of the skiway, and if various man-made subsur...

Ground-penetrating radar studies were performed at South Pole Station, Antarctica, during January 1993 to determine if subsurface obstructions exist along a planned tunnel route from the main station to the new astrophysical research area on the far side of the skiway, and if various man-made subsurface features such as sewage sumps, a water well, utilidors and buried buildings could be located and delineated. The maximum depth of interest for the tunnel survey was approximately 10 m. For it, a short-pulse antenna transducer with its antenna bandwidth centered near 400 MHz was towed along the ground surface over multiple traverses to cover an area up to 60 m wide. The survey extended from the South Pole Station fuel arch, across the skiway and then to the CARA site (Center for Astrophysical Research in Antarctica). The radar profiles show reflections from density layering within the snow caused by traffic and diffractions from artificial features within 13 m depth. Debris is present in the snow west of the skiway and near the fuel bladder near the taxiway. Targets within 100 m of the west side of the skiway are extensive, and appear to be metallic.
