NASA Study Examines Antarctic Sea Ice Increases
11.12.12 - While Arctic sea ice cover is declining dramatically under the effects of climate change, Antarctic sea ice cover has increased in recent years. A new study examines why.

Opposite Behaviors? Arctic Sea Ice Shrinks, Antarctic Grows
10.23.12 - While the Arctic Ocean ice cap has diminished over the last three decades, the sea ice cover at the opposite pole of the planet has expanded.

Antarctic Rift Subject of International Attention
10.15.12 - The rift in Antarctica's Pine Island Glacier that was discovered by NASA's Operation IceBridge in 2011 has been monitored by researchers around the world.

Arctic Sea Ice Hits Smallest Extent In Satellite Era
09.19.12 - The floating, frozen sea ice covering the Arctic Ocean melted to a record low extent on Sept. 16, 2012, continuing a long-term trend that has seen the summer size of the ice cap shrink dramatically in the past three decades.

Arctic Sea Ice Shrinks To New Low In Satellite Era
08.27.12 - The declining sea ice in the Arctic Ocean has melted down to its smallest size since satellite observations began in the late 1970s. The current size of the polar cap surpassed the previous record set in 2007.

Uncovering Antarctica, Pinpointing Penguins
07.23.12 - In 2007, more than 1,100 Landsat 7 images were used to create the first ever, high-resolution, true color map of Antarctica. The Landsat Image Mosaic of Antarctica is a virtually cloud-free, 3-D view of Antarctica's frozen landscape.
