Media Teleconference: Discovery Beneath Antarctic Ice Sheet
Date: Thursday, February 15, 2007 at 2 p.m. EST


Imagine peering down from aboard an airplane flying at 35,000 feet and spotting changes in the thickness of a paper back book on a picnic blanket in New York City's Central Park. If you believe this impossible, NASA satellites are doing the equivalent of just that. From nearly 400 miles above the Earth, satellites have detected for the first time subtle rises and falls in the surface of fast-moving ice streams on the Antarctic ice sheet, a capability that also offers scientists an extraordinary view of interconnected waterways deep below that surface.
