For ten years from 2009 to 2019, the planes of NASA’s Operation IceBridge flew above the Arctic and Antarctic, gathering data on the height, depth, thickness, flow and change of sea ice, glaciers, and ice sheets.
Designed to bridge the gap between NASA’s two Ice, Cloud, and land Elevation Satellites, ICESat and ICESat-2, IceBridge made its final flight in November 2019, one year after ICESat-2’s successful launch. The fleet of aircraft carried more than a dozen instruments, from ice-penetrating radar and elevation-mapping lasers to optical and infrared cameras.
This visualization shows the flight lines of each yearly campaign from 2009 to 2019, created from navigational data obtained from the flights.
