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,...

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...

West Antarctica Deglaciation Began Much Earlier Than Thought
2013-08-15 10:21:16

Lawrence LeBlond for redOrbit.com - Your Universe Online One of the deepest ice cores ever drilled in Antarctica is revealing some interesting evidence about the southern continent’s turbulent past and the role Earth’s orbit played in the history of the ice ages. Scientists have known for more than a century that ice ages come and go due to the wobbling of the Earth as it orbits the sun. Increases in the intensity of summer sunlight in the Northern Hemisphere melted the ice sheets...

Glacial Melt Minimal Effect On Sea Level
2013-08-13 09:47:09

Brett Smith for redOrbit.com - Your Universe Online Occasionally, melt water on top of a glacier will trickle down to the bedrock below and act as a lubricant for the glacier’s movements. Once thought to be a major contributor to sea-level rise, melt water was found to have only a minor effect on sea level in a new study from a team of European and American scientists. Using computer modeling based on observations of Greenland’s ice sheet, the research team concluded glacier...

Greenland Ice Sheet Is Melting From Below
2013-08-12 04:20:03

redOrbit Staff & Wire Reports - Your Universe Online High heat flow from the mantle into the lithosphere is causing the Greenland ice sheet to melt from below, according to new research published in Sunday’s online edition of the journal Nature Geoscience. This phenomenon, the researchers explain, is very variable spatially and originates in an exceptionally thin lithosphere (the Earth’s crust and upper mantle). As a result, they report there is an increase in the heat flow from...

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...
