Airborne Radar Looks Through Thick Ice During NASA Polar Campaigns
2013-12-03 15:23:42

NASA The bedrock hidden beneath the thick ice sheets covering Greenland and Antarctica has intrigued researchers for years. Scientists are interested in how the shape of this hidden terrain affects how ice moves -- a key factor in making predictions about the future of these massive ice reservoirs and their contribution to sea level rise in a changing climate. NASA has been monitoring Antarctic and Arctic ice since 2009 with the Operation IceBridge airborne mission. Although the primary...

Arctic Sea Ice Minimum For 2013 Sixth Lowest On Record
2013-09-23 07:44:57

[ Watch The Video: 2013 Arctic Sea Ice Minimum Animation ] NASA After an unusually cold summer in the northernmost latitudes, Arctic sea ice appears to have reached its annual minimum summer extent for 2013 on Sept. 13, the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado in Boulder has reported. Analysis of satellite data by NSIDC and NASA showed that the sea ice extent shrunk to 1.97 million square miles (5.10 million square kilometers). This...

Satellite Data Not Enough Predict Ice Cap Melt
2013-07-15 09:38:00

Brett Smith for redOrbit.com - Your Universe Online New research from a team of European scientists has found there is not enough satellite data to determine the rate of polar ice cap melt very far into the future and warned against using current trends to predict sea level rise that might result from melting glaciers. The ice sheets on Greenland and Antarctica represent the biggest potential contributor to sea level rise. According to a study published last year including data from...

Martian Surface Changes With The Seasons
2013-01-25 08:51:40

[ Watch the Video: Mars Dry Ice and Dunes ] April Flowers for redOrbit.com - Your Universe Online A new study, led by the Planetary Science Institute's Senior Scientists Candice Hansen, shows that the spring thaw on Mars leads to a variety of geologic changes on the planet's surface. Frozen carbon dioxide, also known as dry ice, is deposited on the dunes surrounding the north pole's permanent water ice polar cap. In the spring, as it begins to sublimate, or change directly from a...

Climate Is The Hot Topic In Doha
2012-12-07 18:50:23

ESA ESA joined international delegates in Doha, Qatar, to discuss how satellite observations show our planet´s most sensitive areas reacting to climate change — and how this information is useful to the people living there. After almost two weeks of talks and negotiations, the UN Climate Change Conference has entered its final phase, when countries are represented mainly by their Ministers of Environment. During the first week of the ℠COP 18´ Conference of the...

Polar Ice Sheet Melt Influenced By Underwater Landscape
2012-10-17 12:25:09

Brett Smith for redOrbit.com - Your Universe Online As average global temperatures rise, climatologists are scrambling to see how this development might affect polar ice sheet melt, which could potentially result in a dangerous rise in sea levels. In studying the polar ice sheets around Antarctica, a group of British researchers has found that the shape of water channels beneath the ice can have a strong effect on ice behavior, temporarily hiding indications of its retreat. A report...

PASADENA, Calif., Sept. 11, 2012 /PRNewswire-USNewswire/ -- NASA's Mars Reconnaissance Orbiter (MRO) data have given scientists the clearest evidence yet of carbon dioxide snowfalls on Mars. This reveals the only known example of carbon dioxide snow falling anywhere in our solar system. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Frozen carbon dioxide, better known as "dry ice," requires temperatures of about minus 193 degrees Fahrenheit (minus 125 Celsius), which is much...

The extent of the sea ice covering the Arctic Ocean has shrunk. According to scientists from NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) in Boulder, Colo., the amount is the smallest size ever observed in the three decades since consistent satellite observations of the polar cap began. NASA and NSIDC scientists will host a media teleconference at 3 p.m. EDT, today, to discuss this new record low for summertime Arctic sea ice cover. The extent of Arctic sea ice...

Arctic Sea Ice Expected To Hit Record Low Soon
2012-08-22 07:46:38

April Flowers for redOrbit.com - Your Universe Online Sea ice in the Arctic Ocean is likely to hit its lowest next week and then keep on shrinking. Scientists at the U.S. National Snow and Ice Data Center say data shows that the sea ice coverage is tracking below the previous record low, set in 2007. Arctic sea ice extent during the first two weeks of August continues to track below the 2007 record low daily ice extents. As of August 13, ice extent is already among the four lowest...
