It is, along with neighboring Thwaites Glacier, one of the main pathways for ice entering the Amundsen Sea from the West Antarctic Ice Sheet and one the fastest-retreating glaciers in Antarctica. Collectively, the region contains enough vulnerable ice to raise global sea level by 1.2 meters (4 feet).Operation IceBridge routinely surveyed the glacier during its annual missions over the continent. || ",

IceBridge utilizes a highly specialized fleet of research aircraft and the most sophisticated suite of innovative science instruments ever assembled to characterize annual changes in thickness of sea ice, glaciers, and ice sheets. In addition, IceBridge collects critical data used to predict the response of earth’s polar ice to climate change and resulting sea-level rise.Now, for the first time since its inaugural flights a decade ago, while IceBridge is mapping Greenland’s ice from the air, one of NASA’s newest satellite missions, the Ice, Cloud and land Elevation Satellite-2 (ICESat-2), is simultaneously mapping that ice from space. || ",

It accomplishes this by reflecting lasers off the ice surface and measuring the time it takes light to return to the aircraft, usually flying between 1000 and 2000 feet above the ground. By combining this timing data with detailed information about the aircraft’s position and attitude from GPS and inertial navigation systems, ATM can measure topography to an accuracy of as small as four inches. By flying ATM over the same swath of ground previously covered by ICESat, researchers can maintain a record of changes.In addition, the precise data from ATM’s navigation system can be fed to pilot displays in the cockpit or even electronically sent to the automatic pilot system, keeping the aircraft aligned with the planned survey track. This keeps the aircraft along the planned ATM survey swath and also benefits the other IceBridge instruments by minimizing aircraft roll and horizontal acceleration. || ",

It will support the same suite of IceBridge instruments also flown in the IceBridge 2009-2012 Arctic and Antarctic campaigns, with exception of the Land, Vegetation, and Ice Sensor (LVIS), which in Arctic 2012 campaign flew on the NASA's new Falcon aircraft.The P-3B last flew with IceBridge on their 2012 Arctic campaign, during which the aircraft made flights out of both Kangerlussuaq and Thule, Greenland and will once again support IceBridge for the Arctic 2013 campaign || ",
