IceBridge Campaign Closes with Four More Flights

NASA’s Operation IceBridge completed four more surveys of the Antarctic, bringing the mission’s six-week-long field campaign to a close.
On Nov. 15, IceBridge carried out a newly-created mission designed to study the Institute Ice Stream near the Ronne Ice Shelf. On this flight researchers collected data on surface elevation, sub-ice bedrock and water depth along paths previously measured by NASA’s Ice, Cloud and Land Elevation Satellite, or ICESat, from 2003 to 2009. This region has been the subject of ground-based studies going back to the 1950s, airborne research by a joint U.S.–Danish project in the 1970s and an effort by Germany’s Alfred Wegener Institute in the 1990s.
Previously IceBridge had flown one line in this area in 2012, so this survey expanded the mission’s record of measurements in Antarctica. Thanks to good weather, researchers collected good data for the entire day with the exception of one five minute stretch where low clouds blocked laser and camera instruments. In addition, ice-penetrating radar detected two steep sidewalls in the bedrock in the Hercules Inlet.
