Radar image of the Gamburtsev Subglacial Mountains in the East Antarctic. This mountain range is believed to be approximately 2,700 metres tall,but is entirely covered by over 600 metres of snow and ice. The range first formed over a billion years ago when several continents collided,but wasn't covered until the East Antarctic Ice Sheet formed 34 million years ago. Between those times glaciers carved deep valleys in the landscape. Data collected by ice-penetrating airborne radar on Twin Otter aircraft from the British Antarctic Survey and the US Antarctic Program between December 2008 and January 2009 | |
