NASA | Sea Ice 2008
Arctic sea ice declined this summer to its second smallest extent in the satellite era, suggesting that the record set in 2007 may not have been an anomaly. If recent trends in the melt rate continue, we could see a virtually ice-free...

NASA | IceBridge Kicks Off Campaign with “New” Aircraft
NASA’s Operation IceBridge is back in the field, but this time, there’s a twist. Instead of using the P-3 or DC-8 aircraft from previous campaigns, they’ve outfitted a C-130 cargo plane for the trip. Science flights begin this week as...

NASA | Operation IceBridge Flies the Ice Caps
Ice caps are simply small versions of ice sheets, measuring in at a maximum area of 50,000 square kilometers (about 19,000 square miles). It's their small and thin stature that makes ice caps more prone to melt in a warming Arctic....

NASA | IceBridge Flies High over Both Poles
For the first time NASA’s Operation IceBridge is flying simultaneous missions over both the Arctic and Antarctic, on smaller, faster aircraft. These campaigns and aircraft represent both a unique opportunity for measuring polar ice, and...

NASA | A Tour of the Cryosphere 2009
It has been said that the frozen parts of our planet, also known as the cryosphere, may be the proverbial 'canary in the coal mine' when it comes to climate change. This video shows some of the most dramatic fluctuations to our...

NASA | Operation IceBridge Discovers Massive Crack in Ice Shelf
In October, 2011, NASA's Operation IceBridge discovered a major rift in the Pine Island Glacier in western Antarctica. This crack, which extends at least 18 miles and is 50 meters deep, could produce an iceberg more than 800 square...

Landsat's Global View of Ice Velocity
Ice from glaciers constantly flows into the ocean, but the speed the ice moves at changes. Landsat 8 provides near-real-time mapping of ice speed in nearly all the world’s frozen regions. Information like ice speed helps scientists study...
