Encased in its insulated cover for thermal stability, a gravimeter was installed in the cabin of NASA’s DC-8 flying laboratory in preparation for Operation IceBridge. The sensor, managed by Columbia University, allowed scientists to measure the shape of the ocean cavity beneath floating Antarctic ice shelves. Operation Ice Bridge is a multi-year study that tracks changes in Antarctica’s sea ice, glaciers, and ice sheets.September 29, 2009
