Andrew Lloyd, a Ph.D. student at St. Louis's Washington University, spent many weeks traveling across Antarctica's barren ice sheet to retrieve seismographs instruments scientists are using to map the geology far beneath Antarctica, something that has never been done before.

Lloyd and others set off on snowmobiles from their home base, Byrd Camp.

The installation of the seismograph network is part of a project called Polenet. Here, the traveling researchers have set up camp for the night. The camp faces north toward Mt. Waesche (left) and Mt. Sidley (middle).

The team takes down a seismic station. Held within the instrument are data that will help scientists make a picture of the geology some 60 miles (100 kilometers) underneath the continent.
