West Antarctica's Ice Sheet 20 Million Years Older Than Previosuly Estimated
2013-09-05 07:26:16

April Flowers for redOrbit.com - Your Universe Online A research team led by professors at the University of California Santa Barbara (UCSB) has revealed that, contrary to popular belief, an ice sheet on West Antarctica existed 20 million years earlier than previously thought. These results, published in Geophysical Research Letters, mark a paradigm shift for our understanding of the Earth’s great global ice sheets. Ice sheets first grew on the West Antarctic subcontinent around 34...

Black Carbon Suspect In Mid-1800s Alps Glacier Retreat
2013-09-03 08:17:32

University of Colorado at Boulder Scientists have uncovered strong evidence that soot, or black carbon, sent into the air by a rapidly industrializing Europe, likely caused the abrupt retreat of mountain glaciers in the European Alps. The research, published Sept. 2 in the Proceedings of the National Academy of Sciences, may help resolve a longstanding scientific debate about why the Alps glaciers retreated beginning in the 1860s, decades before global temperatures started rising again....

Grand Canyon Found Lurking Beneath Greenland's Ice Sheet
2013-08-30 04:06:35

[ Watch the Video: Greenland’s Mega Canyon ] redOrbit Staff & Wire Reports - Your Universe Online One of the largest canyons in the world has been discovered beneath the Greenland ice sheet, according to new research appearing in the latest edition of the journal Science. Lead author Jonathan Bamber, a professor at the University of Bristol’s School of Geographical Sciences, and colleagues report the canyon is at least 460 miles (750km) long, up to 2,600 feet (800m) deep in...

Will Climate Change Make The East Antarctic Ice Sheet More Vulnerable?
2013-08-29 05:41:31

April Flowers for redOrbit.com - Your Universe Online New research from Durham University’s Department of Geography reveals the world’s largest ice sheet could be more vulnerable to the effects of climate change than previously thought. A team of researchers used declassified spy satellite imagery from 1963 to 2012 to create the first long-term record of changes in the terminus of outlet glaciers – where they meet the sea – along 3,355 miles of the East Antarctic Ice Sheet's...

The Ice Surrenders Its Secrets Floe By Floe
2013-08-27 12:28:35

AlphaGalileo Foundation Bowhead and minke whale sightings, extensive ice floe measurements and the successful retrieval of important moored instruments are among the successes of a multinational team of ice engineering researchers and marine biologists during their first week off the coast of northeastern Greenland on the Swedish icebreaker Oden. “The general atmosphere on the cruise is quite good,” says Raed Lubbad, cruise director and an associate professor at the Norwegian...

Last Glacial Maximum Peaked In Spain Much Earlier Than Elsewhere
2013-08-26 14:15:13

Brett Smith for redOrbit.com - Your Universe Online While it’s widely believed that the world’s massive ice sheets were at their greatest extent 20,000 years ago during the last glacial maximum, new research published in Scientific Reports suggested that the glacial peak was much earlier in modern-day Spain. According to study researchers, their findings could inform more localized models of glacier activity and be used to calculate the effects of climate change. “We wanted to...

Sea Ice Decline Changing The Vegetation Of The Arctic
2013-08-23 10:26:03

Geophysical Institute, University of Alaska Fairbanks Sea ice decline and warming trends are changing the vegetation in nearby arctic coastal areas, according to two University of Alaska Fairbanks scientists. Uma Bhatt, an associate professor with UAF’s Geophysical Institute, and Skip Walker, a professor at UAF’s Institute of Arctic Biology, contributed to a recent review of research on the response of plants, marine life and animals to declining sea ice in the Arctic. “Our...

2013 Ice Melt Will Not Be Record Year Despite Continuing Downhill Trends
2013-08-23 10:06:14

[WATCH VIDEO: Summer Arctic Ice Retreat 2013] Lee Rannals for redOrbit.com - Your Universe Online Arctic sea ice is reaching its annual "minimum" melt for the summer, but NASA says this year's low will unlikely be breaking any records. Last year, Arctic sea ice melted to a record low, making it the largest summer melt since satellites began measuring the process in 1979. This year's melt is beginning to reach its minimum now, and even though it’s not going to catch any records,...

2013-08-21 14:26:33

A new paper co-written by UM associate professor Mark Hebblewhite details ecological changes caused by a loss of Arctic sea ice. The paper concludes that the loss of sea ice obviously will impact the marine food web and the marine mammals that depend on sea ice habitat. Other major ecological changes in adjacent land-based habitats and species also will occur because of warming oceans. The findings were published in the Aug. 2 issue of Science magazine. Wildlife species like the polar...

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...
