Frozen EarthFrozen Earth

Ice covers 10 percent of Earth's surface and helps moderate the planet's temperature. Glaciers and ice sheets around the world are melting at an alarming rate. By keeping an eye on Earth's ice from space, NASA satellites help us understand the global effects of climate change.

A Tour of the Cryosphere 2009A Tour of the Cryosphere 2009

The cryosphere is Earth's solid water: snow, sea ice, glaciers, permafrost, ice sheets, and icebergs. Direct measurements can be difficult to obtain, so scientists use satellites to observe the cryosphere and to monitor changes.

Sea Ice 2008Sea Ice 2008

Arctic sea ice has shrunk dramatically in the last few decades. If recent trends in the melt rate continue, the Arctic Ocean could be ice free in the summer much sooner than previously thought.

Operation Ice BridgeOperation Ice Bridge

IceBridge, a six-year NASA mission, is the largest airborne survey of Earth's polar ice ever flown. It will yield an unprecedented three-dimensional view of Arctic and Antarctic ice sheets, ice shelves and sea ice. These flights will provide a yearly, multi-instrument look at the behavior of the rapidly changing features of the Greenland and Antarctic ice.

Guided Tour of Antarctic FlyoverGuided Tour of Antarctic Flyover

This guided tour of the area surrounding McMurdo Station in Antarctica uses the Landsat Image Mosaic of Antarctica (LIMA). It's a great way to experience the frozen continent without any risk of frostbite.
