Scientists Discover New Site of Potential Instability in West Antarctic Ice Sheet

Scientists Discover New Site of Potential Instability in West Antarctic Ice Sheet

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…   » Continue Reading

New Map Reveals Giant Fjords Beneath East Antarctic Ice Sheet

Scientists have used ice-penetrating radar to create the first high-resolution topographic map of one of the last uncharted regions of Earth, the Aurora Subglacial Basin, an immense ice-buried lowland in East Antarctica. The map will help improve computer simulations of the past and future Antarctic ice sheet and its potential impact on global sea level.
