Arctic Sea Ice Reaches Lowest Coverage for 2008
09.16.08 -- Arctic sea ice coverage appears to have reached its lowest extent for 2008 and the second-lowest amount recorded since the dawn of the satellite era.

Crack in the Petermann Glacier
09.12.08 -- Researchers at the Byrd Polar Research Center at Ohio State University have expressed concern at the presence of a rift in Greenland's Petermann Glacier.

Retreat of Serson Ice Shelf
09.11.08 -- As recently as the early 1900s, the northern coast of Canada's Ellesmere Island was fringed by a continuous expanse of ice. By July 2008, warming Arctic climate had reduced the continuous ice to five isolated shelves. In July and Aguust three of the shelves experienced further significant retreat.

Both Routes Around Arctic Open at Summer's End
09.09.08 -- As of the first week of September 2008, Arctic sea ice extent had not fallen below 2007's record low, but for the first time since satellite observations began three decades ago, sea ice retreated enough to create open waters all the way around the northern ice pack.

Wintertime Disinteghration of Wilkins Ice Shelf
07.19.08 -- On the Antarctic Peninsula, the Wilkins Ice Shelf historically extended toward Charcot Island in the northwest, and Latady Island in the southwest. By July 2008, the ice shelf's connection to Charcot Island, which had helped to hold the shelf in place, was nearly gone.
Feature
For Toy-Like NASA Robots in Arctic, Ice Research is Child's Play
07.15.08 -- SnoMotes are the first prototype network of their kind envisioned to rove treacherous areas of the Arctic and Antarctic.
Feature
Researchers Warm Up to Melt's Role in Greenland Ice Loss
04.17.08 -- Whether or not summertime melt has a significant influence on Greenland ice loss has been an endless topic of debate among scientists -- until now.
Feature
Researchers Say Arctic Sea Ice Still at Risk Despite Cold Winter
03.19.08 -- Using the latest satellite observations, NASA researchers and others report that the Arctic is still on 'thin ice' when it comes to the condition of sea ice cover in the region.
Multimedia
2008 Arctic Sea Ice Concentration Map
03.18.08 -- Using the latest satellite observations from early 2008, NASA researchers and others report that the Arctic is still on 'thin ice' when it comes to the condition of sea ice cover in the region. This ice concentration map from March 9, 2008, shows maximum extent of sea ice in the Northern Hemisphere.
Multimedia
Arctic Sea Ice Distribution by Age
03.18.08 -- The sea ice in the Arctic is much younger than normal, with vast regions now covered by first-year ice. The left image shows February distribution of ice by its age during normal Arctic conditions (1985-2000 average), and the right illustrates February 2008 Arctic ice age distribution.
