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.
NASA cryospheric scientist Kelly Brunt and other members of the NASA Cryospheric Science Laboratory endure low temperatures, high winds and high altitude to conduct the 88-South Traverse: a 470-mile expedition in one of the most barren and remote landscapes on Earth, towards validation of the ICESat-2 satellite.
