Who is studying Earth's polar ice in Antarctica? We are during Operation IceBridge, an airborne science mission by NASA. 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.

Operation IceBridge is conducting its first field campaign directly from Antarctica this year. Seen here, NASA flight engineer Brian Yates directs the P-3 research aircraft during engine startup on the ramp at McMurdo Station's sea ice airfield before a Nov. 20 survey flight over Victoria Land in Antarctica. To the right in the background is the nearby volcano, Mount Erebus.
