SwRI study suggests debris flows on frozen arctic sand dunes are similar to dark dune spot-seepage flows on Mars
San Antonio TX (SPX) Sep 10, 2013
A team of scientists from Southwest Research Institute (SwRI) has demonstrated that frozen water in the form of snow or frost can melt to form debris flows on sunward-facing slopes of sand dunes in the Alaskan arctic at air temperatures significantly below the melting point of water. The debris flows consist of sand mixed with liquid water that cascade down steep slopes. SwRI scientists made their observations at the Great Kobuk Sand Dunes, in Kobuk Valley National Park, Alaska. This site serves a ... read more
