LAWRENCE — Kansas University researchers have helped find a massive canyon, about two times larger than the Grand Canyon, buried under miles of ice in Greenland. The discovery appears in Friday’s edition of the journal “Science.” The article, authored by Jonathan Bamber of the University of Bristol in England, maps and describes a previously unknown canyon in Greenland that is 470 miles long and twice as deep in some spots as the Grand Canyon, and located under a two-mile blanket of ice. Data from special radars developed by KU’s NSF Center for Remote Sensing of Ice Sheets helped to find and chart the canyon, said KU professor Prasad Gogineni, distinguished professor of electrical engineering and computer science at KU and director of the center. The KU center develops ice-penetrating radars and unmanned aircraft to study changes in earth’s polar ice sheets, and its data is used by scientists across the world to better predict climate change and the effect melting ice sheets have on sea levels.
