East Antarctica Is Pushing Around Its Softer-Mantled Western Half
2013-12-12 07:51:20

April Flowers for redOrbit.com - Your Universe Online It's easy to know what to do when half-siblings are pushing each other around, but what do you do about half-continents? A team of researchers, led by Ohio State University, have discovered that East Antarctica is pushing West Antarctica around. West Antarctica is losing weight in the form of billions of tons of ice per year, making its mantle rock softer. This rock is being nudged westward by the harder mantle beneath East...

Long Unchanged Alpine Glacier Is Now Melting At Unprecedented Rate
2013-12-12 06:35:56

April Flowers for redOrbit.com - Your Universe Online An international team of glaciologists, led by Ohio State University, has discovered new and compelling evidence that the Italian Alps are warming at an unprecedented rate. The discovery, described at the annual autumn meeting of the American Geophysical Union this past week, was made less than 20 miles from the site where melting ice exposed the 5,000-year-old body of Ötzi the Iceman. A single, dried-out leaf from a larch tree...

ESA CryoSat Mission Confirms Antarctic Ice Loss Is On The Rise
2013-12-12 06:08:21

Alan McStravick for redOrbit.com - Your Universe Online With news out of San Francisco this week, at the autumn meeting of the American Geophysical Union (AGU), we learned scientists have incorrectly estimated the amount of ice being lost on the polar continent of Antarctica. This environmental faux pas directly affects the estimates on global sea level rise as well. The team presenting these findings conducted their research with the Natural Environment Research Council’s Center for...

Antarctic High Ridge Gets Distinction As Coldest Place On Earth
2013-12-10 09:03:50

[ Watch the Video: Coldest Place On Earth Is The East Antarctic Plateau ] redOrbit Staff & Wire Reports - Your Universe Online If you think it’s cold where you live, consider this: NASA satellites have just discovered the chilliest place on Earth, where temperatures can plummet to minus 133.6 degrees Fahrenheit (minus 92 degrees Celsius). This “glad I don’t live there” location is a high ridge in Antarctica on the East Antarctic Plateau, where temperatures in several...

Extreme Summer Weather May Be Caused By Ice Loss In The Arctic
2013-12-09 11:16:06

redOrbit Staff & Wire Reports - Your Universe Online The cause of increasingly intense summer heat waves and downpours throughout the US and Europe could be due to thawing Arctic ice and snow, according to new research published Sunday in the journal Nature Climate Change. In the study, researchers from the Chinese Academy of Sciences and the Rutgers University Institute of Marine and Coastal Sciences looked at satellite observations of snow cover and sea-ice extent during the...

The Health Of Antarctic Glaciers Relies On Salt Intake: NASA
2013-12-06 10:19:26

April Flowers for redOrbit.com - Your Universe Online An intriguing link between sea ice conditions and the melting rate of Totten Glacier, the glacier in East Antarctica that discharges the most ice into the ocean, has been found by a NASA-led study. The discovery, published in Nature Communications, involves cold, extra salty water—brine—that forms within openings in sea ice. The findings will add to our understanding of how ice sheets interact with the ocean, and may improve our...

Scientists Find Rapid Warming Threatens Rich Seafloor Communities
2013-12-04 10:09:25

University of Hawaii at Manoa Deep inside the dramatic subpolar fjords of Antarctica, researchers from the University of Hawai'i at Mānoa have discovered an unexpected abundance and diversity at the seafloor. During a recent expedition, UH scientists for the first time studied the seafloor communities of glacier dominated fjords along the west Antarctic Peninsula, a region undergoing very rapid climate warming. The scientists expected to find impoverished seafloor communities highly...

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...

Warm Water Causes Arctic Glaciers To Sizzle As They Melt
2013-11-28 06:11:28

[ Watch the Video: Melting Glacial Ice Has Its Own Sound ] April Flowers for redOrbit.com - Your Universe Online One of the most prominent sounds of a warming planet has been recorded and identified by scientists at the University of Alaska: the sizzle of glacial ice as it melts into the sea. Trapped air bubbles squirting out of the disappearing ice causes a noise that might provide clues to the rate of glacier melt and help researchers better monitor the fast-changing polar...

Greenland Ice Sheet Is Hiding Subglacial Lakes
2013-11-28 04:29:14

redOrbit Staff & Wire Reports - Your Universe Online Researchers have discovered a pair of subglacial lakes discovered over 800 meters beneath the Greenland Ice Sheet – the first ever to be discovered in the island nation, according to research appearing in the latest edition of the journal Geophysical Research Letters. The two lakes are reportedly between eight and 10 square kilometers in surface area, but might have been up to three times larger than their current size at one...

Columbia Plateau
2013-04-19 16:35:47

The Columbia Plateau ecoregion is a Level III ecoregion designed by the United States Environmental Protection Agency in the U.S. states of Oregon and Washington, with little areas over the Washington state border in Idaho. This ecoregion stretches across a wide swath of the Columbia River Basin from the Dalles, Oregon to Lewiston, Idaho to Okanogan, Washington near the Canadian border. It incorporates nearly 500 miles of the Columbia River, as well as the lower reaches of major tributaries....

Arctic Ocean
2013-04-18 22:31:23

The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...

Meltwater
2009-07-06 17:15:30

Meltwater is water that is released from melting snow or ice. This includes meltwater from glacial ice and ice shelves over oceans. Meltwater is often produced during volcanic eruptions, and can cause dangerous lahars (landslides of wet volcanic debris). When meltwater pools on the surface rather than draining or flowing away, it forms pools known as melt ponds. Meltwater will often refreeze as the temperature drops. Meltwater can also collect or melt under the ice's surface. Sub-glacial...
