Iceberg Wallpaper: Iceberg Download May 3, 2013 | Author: AAAS Fellow, Evan Pugh Professor, Dept. of Geosciences, and Earth and Environmental Systems Institute, Penn State Richard Alley The great ice sheets of Greenland and Antarctica are huge piles of old snow compressed to ice, and spreading under their own weight. They grow by snowfall on top, and shrink by melting around the sides and by formation of icebergs in marginal seas. Recently, both Greenland and Antarctica have been losing mass, partly because of faster melting on Greenland in warmer air, but also because of melting in warmer ocean water. Winners of 2013 AAAS Student Poster Competition Tuesday, April 30, 2013 The 2013 Student Poster Competition took place at the AAAS Annual Meeting In Boston February 14-18.

Endurance sinking Triumph and tragedy in a most hostile place Scientia February 7, 2013 In the news are two stories about Antarctic science expeditions that illuminate the triumph and tragedy that mark all such expeditions. One, concerning the drilling through Antarctic ice to reach a sub-glacial lake, has been successful. The other, the crash of a plane that was to be part of Italy’s polar research program, serves as a reminder of how hazardous any Antarctic expedition can be. Though all expeditions to Antarctica have been marked by triumph, tragedy or both, one early expedition stands out as being perhaps the most arduous, and, in its own way, successful expedition, despite the fact that it didn’t come close to achieving its goal -- the aptly named Endurance expedition of Ernest Shackleton.
