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...

WASHINGTON, March 12, 2014 /PRNewswire-USNewswire/ -- Researchers aboard NASA's P-3 research aircraft left the agency's Wallops Flight Facility in Wallops Island, Va., March 10 for Greenland to begin a new season of collecting data on Arctic land and sea ice. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The mission, known as Operation IceBridge, is to gather data on changes to polar ice and maintain continuity of measurements between NASA's Ice, Cloud and Land Elevation...

Greenland Jakobshavn Glacier
2014-03-12 04:40:59

Lee Rannals for redOrbit.com - Your Universe Online New data obtained by NASA's Operation IceBridge program is shedding new light on how ice sheets in Greenland are changing. Scientists used satellite observations and ice thickness measurements made by Operation IceBridge to determine the rate at which ice flows through Greenland’s glaciers into the ocean. The findings have shown how glacier flow is affecting the Greenland Ice Sheet and that this process is being dominated by a small...

Warm Rivers Play A Role In Arctic Sea Ice Melt
2014-03-06 06:32:21

Brett Smith for redOrbit.com - Your Universe Online According to a new study from NASA researchers, warm river waters draining into the Arctic Ocean are adding to the melting of sea ice in the Arctic Ocean each summer. Published in the journal Geophysical Research Letters, researchers reported on an abrupt inflow of warm river water into the Arctic Ocean that swiftly warmed the top layers in the sea, fueling the melting of summer ice. “River discharge is a key factor contributing...

Arctic Sea Ice Trends

April Flowers for redOrbit.com - Your Universe Online According to new research from the University College London, the melt season across the Arctic is getting longer by five days every ten years. Julienne Stroeve, Professor of Polar Observation and Modeling at UCL Earth Sciences, led the team in analyzing satellite data. The analysis, published in Geophysical Research Letters, revealed that the Arctic Ocean is absorbing even more of the sun’s energy in summer, leading to an even...

Antarctic ice shelf
2014-03-03 05:04:27

McGill University In the mid-1970s, the first available satellite images of Antarctica during the polar winter revealed a huge ice-free region within the ice pack of the Weddell Sea. This ice-free region, or polynya, stayed open for three full winters before it closed. Subsequent research showed that the opening was maintained as relatively warm waters churned upward from kilometers below the ocean's surface and released heat from the ocean's deepest reaches. But the polynya -- which...

Bering Land Bridge Was Home To Early Natives For 10,000 Years: Study
2014-02-28 09:47:53

April Flowers for redOrbit.com - Your Universe Online After the ancestors of modern day Native Americans left Asia, they spent approximately 10,000 years living in the shrubby lowlands of the Bering land bridge, according to genetic and environmental evidence. There is no available archaeological evidence, however, because it drowned beneath the Bering Sea when the sea levels rose about 18,000 years ago. Dennis O'Rourke, a University of Utah anthropologist, worked with archaeologist...

Adelies Ross Sea ice floes
2014-02-27 05:21:14

April Flowers for redOrbit.com - Your Universe Online The Ross Sea is a major, biologically productive ecosystem in the Antarctic, which "clearly will be extensively modified by future climate change" in the coming decades as longer periods of ice-free open water are created by rising temperatures and changing wind patterns. According to a new paper funded by the National Science Foundation (NSF), these ice-free periods affect the life cycles of both predators and prey. The research...

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...
