Expanding Jakobshavn Coverage

NASA's Operation IceBridge continued its 2014 Arctic campaign with a survey of the rapidly changing Jakobshavn Glacier and a survey that included a pass over the National Science Foundation's Summit Station. Both of these flights are part of the newly classified set of seven baseline missions designed to monitor elevation in rapidly changing parts of Greenland.
The morning of Apr. 9 was another chilly one, with a low temperature of around -15 degrees Fahrenheit. After warming up the P-3 and its instruments, the IceBridge team took off for a survey of Jakobshavn Glacier, the fastest moving one in Greenland.
After taking off from Kangerlussuaq, the P-3 turned north and flew a series of north-south lines over Jakobshavn Glacier, gradually moving toward the coast and then flying up the glacier's centerline. The rest of the flight covered tracks previously measured by NASA's ICESat satellite. Comparing current measurements with these historic ICESat lines allows researchers to determine how ice elevation has changed there.

IceBridge Mission Statement
NASA’s Operation IceBridge images Earth's polar ice in unprecedented detail to better understand processes that connect the polar regions with the global climate system. 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. IceBridge also helps bridge the gap in polar observations between NASA's ICESat satellite missions.
