NASA Studies an Unusual Arctic Warming Event
Winter temperatures are soaring in the Arctic for the fourth winter in a row. The heat, accompanied by moist air, is entering the Arctic not only through the sector of the North Atlantic Ocean that lies between Greenland and Europe, as...

NASA Laser, ESA Radar Sync Up for Sea Ice
In July 2020, ESA elected to slightly perturb the orbit of CryoSat-2 to increase the overlap with ICESat-2. Given their different orbit altitudes, the result is a roughly 1,864-mile (3,000-km) stretch of sea ice that is measured by both...

NASA | OIB: Sea Ice Interlude
Sea ice doesn't always hold the allure of a massive ice sheet, or a crevassed blue glacier spilling between mountains, but it comes in array of shapes and sizes and has its own ephemeral beauty. Operation IceBridge studies sea ice at...

NASA | OIB: NASA and ESA in an Arctic Alliance
For the second straight year, NASA's Operation IceBridge is collaborating with the European Space Agency's CryoVEx program, flying aircraft low over Arctic sea ice while ESA's CryoSat satellite orbits above. In this video, IceBridge...

NASA | OIB Flights South 2014: A Sea Ice Mystery
Where’s it coming from? With global average temperatures rising, it would be natural to assume that total quantities of sea ice would be falling. But it’s not. Scientists have begun to observe sea ice increases around Antarctica, and the...

NASA | A Selective History of Arctic Sea Ice Observations, Part 2
The study of Arctic sea ice changed forever with the dawn of the Space Age and the first Earth-observing satellites. Part 2 of our animated timeline picks up where Part 1 left off — with the launch of the TIROS weather satellite.
