NASA Antarctic Ice News

NASA's Jet Propulsion Laboratory held a press conference to discuss the West Antarctic Ice Sheet and its potential contribution to future sea level rise. The new study by researchers at NASA and the University of California, Irvine, finds a rapidly melting section of the West Antarctic Ice Sheet appears to be in an irreversible state of decline, with nothing to stop the glaciers in this area from melting into the sea.

A new study led by NASA researchers shows that half-a-dozen key glaciers in the West Antarctic Ice Sheet are in irreversible decline. The melting of these sprawling icy giants will affect global sea levels in the centuries ahead.

First Radar Vision for Copernicus

Launched on 3 April, ESA's Sentinel-1A satellite has already delivered its first radar images of Earth. They offer a tantalising glimpse of the kind of operational imagery that this new mission will provide for Europe's ambitious Copernicus environmental monitoring programme.

NASA hosted a Google+ Hangout news conference on Tuesday, Oct. 29 to share information about Operation IceBridge's upcoming airborne field campaign in Antarctica.

The ozone hole that forms each year in the stratosphere over Antarctica was slightly smaller in 2013 than average in recent decades, according to NASA satellite data.

ESA is accepting proposals for scientific research using two of its human spaceflight 'analogue' platforms: bedrest studies and the Concordia station in Antarctica. Such experiments increase our knowledge of human risks in spaceflight today, and especially help to prepare for future long-duration exploration missions.

For five years, a scientific expedition tried reaching Pine Island Glacier ice shelf in a remote, wind-ridden corner of Antarctica. The obstacles to get to the ice shelf were extreme, but the science goal was simple: to measure how fast the sea was melting the 37-mile long ice tongue from underneath by drilling through the ice shelf.

For more than a century scientists have known that Earth's ice ages are caused by the wobbling of the planet's orbit, which changes its orientation to the sun and affects the amount of sunlight reaching higher latitudes, particularly the polar regions.

New Ice Island in Antarctica

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument--built by Japan's Ministry of Economy, Trade, and Industry for NASA's Terra satellite--acquired this image of two widening cracks along an edge of the Pine Island Glacier in Antarctica.

Ocean waters melting the undersides of Antarctic ice shelves are responsible for most of the continent's ice shelf mass loss, a new study by NASA and university researchers has found.
