Potential instability in West Antarctic Ice Sheet from newly discovered basin size of New Jersey

Potential instability in West Antarctic Ice Sheet from newly discovered basin size of New Jersey

ScienceDaily (May 10, 2012) — Using ice-penetrating radar instruments flown on aircraft, a team of scientists from the U.S. and U.K. have uncovered a previously unknown sub-glacial basin nearly the size of New Jersey beneath the West Antarctic Ice Sheet (WAIS) near the Weddell Sea. The location, shape and texture of the mile-deep basin suggest that this region of the ice sheet is at a greater risk of collapse than previously thought.
