New Twist On Arctic Melt Revealed By River Ice
2014-04-04 09:32:47

Simon Fraser University A new study led by Lance Lesack, a Simon Fraser University geographer and Faculty of Environment professor, has discovered unexpected climate-driven changes in the mighty Mackenzie River’s ice breakup. This discovery may help resolve the complex puzzle underlying why Arctic ice is disappearing more rapidly than expected. Lesack is the lead author on Local spring warming drives earlier river-ice breakup in a large Arctic delta. Published recently in Geophysical...

Measuring Changes In Polar Ice Sheets Using Unmanned Aircraft

[ Watch The Video: Researchers Test Drones To Monitor Antarctic Ice ] National Science Foundation Boldly going where larger, human-piloted planes cannot, they promise to close a key gap in knowledge for climate modelers Scientists studying the behavior of the world's ice sheets--and the future implications of ice sheet behavior for global sea-level rise--may soon have a new airborne tool that will allow radar measurements that previously would have been prohibitively expensive or...

National Snow and Ice Data Center Will next year’s summer Arctic ice extent be high or low? Can ship captains plan on navigating the famed Northwest Passage — a direct shipping route from Europe to Asia across the Arctic Ocean — to save on time and fuel? A new study says year-to-year forecasts of the Arctic’s summer ice extent are not yet reliable. Scientists at the National Snow and Ice Data Center (NSIDC), University College London, University of New Hampshire and University...

Major Increase In West Antarctic Glacial Loss
2014-03-28 17:26:44

American Geophysical Union Six massive glaciers in West Antarctica are moving faster than they did 40 years ago, causing more ice to discharge into the ocean and global sea level to rise, according to new research. The amount of ice draining collectively from those half-dozen glaciers increased by 77 percent from 1973 to 2013, scientists report this month in Geophysical Research Letters, a journal of the American Geophysical Union. Pine Island Glacier, the most active of the studied...

Lake Towuti

Brown University Using sediments from a remote lake, researchers from Brown University have assembled a 60,000-year record of rainfall in central Indonesia. The analysis reveals important new details about the climate history of a region that wields a substantial influence on the global climate as a whole. The Indonesian archipelago sits in the Indo-Pacific Warm Pool, an expanse of ocean that supplies a sizable fraction of the water vapor in Earth's atmosphere and plays a role in...

Moss Still Lives After 1500 Years Buried In Antarctic Ice
2014-03-17 14:57:18

Brett Smith for redOrbit.com - Your Universe Online British researchers who typically study polar moss samples because they provide indications of past climate conditions have found that Antarctic moss can survive trapped under ice for over 1,500 years. While some plant material has been brought back to life after 20 years of being frozen, only microbes have been shown to be capable of thousand-year feats of revival; that is until now. "These mosses were basically in a very long-term...

Greenland Ice Sheet Receding And Is Now Considered Unstable
2014-03-17 10:26:10

Brett Smith for redOrbit.com - Your Universe Online According to a new report in the journal Nature Climate Change, the last stable section of the Greenland ice sheet is receding and now considered unstable – a development that could portend even more ice loss in the future and significant sea level rise. The report focused on a key ice stream in the Greenland ice sheet. Ice streams drain an ice basin from the interior of the sheet, in the same way that regular streams drain water...

Unraveling Mystery Of Retreating Glaciers In The Pacific Ocean's Western Tropics
2014-03-14 11:39:06

University of California - Los Angeles Using a cutting-edge research technique, UCLA researchers have reconstructed the temperature history of a region that plays a major role in determining climate around the world. The findings, published online Feb. 27 in the journal Nature Geoscience, will help inform scientists about the processes influencing global warming in the western tropical Pacific Ocean. The study analyzes how much temperatures have increased in the region near...

redOrbit Staff & Wire Reports - Your Universe Online Scientists working on NASA’s Operation IceBridge mission are en route to Greenland to kick off this year’s Arctic land and sea ice data collection efforts, officials from the US space agency announced on Wednesday. On Monday, the researchers departed from the Wallops Flight Facility in Wallops Island, Virginia on board the agency’s P-3 research aircraft. They will be collecting and reporting valuable information on rapidly...

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...
