Determining the Age of Antarctic Ice
April 23, 2014 | National Science Foundation

“A team of scientists, funded by the National Science Foundation, has successfully used a new technique to confirm the age of a 120,000-year-old sample of Antarctic ice. The new dating system is expected to allow scientists to identify ice that is much older, thereby reconstructing climate much farther back into Earth’s history and potentially leading to an understanding of the mechanisms that cause the planet to shift into and out of ice ages.” Quoted from the NSF press release.

Using Unmanned Aircraft to Survey Polar Ice
April 8, 2014 | National Science Foundation

[...] IceCube is an [...] astrophysical telescope deployed deep in the Antarctic ice (from 1.4 to 2.4 km depth), but looks over the entire universe, detecting neutrinos coming through the Earth from the Northern skies, as well as from around the Southern skies,” Quoted from the National Science Foundation press release.

A Rumbling Volcano Beneath Antarctic Ice?
November 18, 2013 | Washington University

“My first thought was, ‘OK, maybe it’s just coincidence.’ But then I looked more closely and realized that the mountains were actually volcanoes and there was an age progression to the range.
