Video of the Week: ICESat-2 Scans Glaciated Volcanoes in the Pacific Northwest

In this week’s Video of the Week, Polar Science Center glaciologist Ben Smith shares results from NASA’s new polar satellite, ICESat-2, which made a pass over two glaciated volcanoes in the Pacific Northwest; Mount Baker and Mount Adams. The satellite, which launched in September 2018, carries a laser altimeter that detects individual photons, allowing scientists to measure the elevation of ice sheets, sea ice, forests and more in unprecedented detail. Smith, who is also a professor at the University of Washington, said it will be a few years before the polar orbiting satellite passes over the region, providing an opportunity to measure the glaciers’ change in surface altitude again.
