IceBridge, Arctic 2011
Researchers and flight crew arrived in Thule, Greenland, on Monday, March 14, for the start of NASA's 2011 Operation IceBridge, an airborne mission to study changes in Arctic ice. This year's plans include surveys of Canadian ice caps and expanded international collaboration. Flights will also be made from Kangerlussuaq, Greenland, and Fairbanks, Alaska.

The state of Earth's polar ice sheets, glaciers and sea ice is an important indicator of climate change and plays a key role in regulating global climate. With IceBridge, NASA is pushing ahead with its commitment to keep an eye on changes to polar ice to better understand the effects of climate change.
