In a series of 39 flights lasting eight hours each, NASA’s Operation IceBridge – the largest airborne survey of Earth’s polar ice – conducted critical surveys of our planet’s polar regions to trace their changing features.
This year has provided the best data of all the IceBridge operations. A wider area was covered than ever before, while new instruments allowed for more accurate measurements to be made.
The IceBridge team were able to study a newly discovered crack on the ice shelf of Petermann Glacier in Greenland. Because the rift only developed very recently, the measurements collected will help scientists better understand the evolution of cracks.
