Watch and hear about 'what lies beneath' Antarctica's ice

Sridhar Anandakrishnan is exploring a new frontier beneath the ice of Antarctica. He and his team traveled to Ross Island in December to search for a body of water that some scientists say lies deep below the surface of the South Pole. By lowering explosives into deep holes, the team can record rebound sounds through geophones and estimate the distance to the bottom of the ice. The resulting seismic data is used to create cross-section maps of the ice sheets. Anandakrishnan hopes that the data will help to predict future changes in sea-level and possibly unveil new microscopic organisms.

WPSU-FM's Cynthia Berger provided Anandakrishnan with equipment to record an audio diary from the field. In the video below, Anandakrishnan narrates the setting and detonation of a seismic shot. In the video clips at left, "Dr. A.," back at home, describes in more detail the process of mapping Antarctica’s ice.
