1 00:00:04,000 --> 00:00:08,000 NASA’s Operation IceBridge has been monitoring Arctic sea ice from planes for a decade. 2 00:00:08,000 --> 00:00:12,000 During four flights in April, it followed the orbital paths of the new ICESat-2 satellite. 3 00:00:16,000 --> 00:00:20,000 The plane and satellite measured the same stretch of sea ice at the same time. 4 00:00:24,000 --> 00:00:28,000 These images taken by IceBridge’s CAMBOT instrument show sea ice floes and leads during one of the four flights.
