West Antarctic Ice Sheet
2014-07-12 06:07:29

redOrbit Staff & Wire Reports - Your Universe Online Much of the climate change-related research published recently has focused on the impact of warming temperatures on the West Antarctic ice sheet – but what is it about this region that causes scientists to be so interested in it? According to the US National Oceanic and Atmospheric Administration (NOAA), the West Antarctic ice sheet contains two major slabs of frozen water (the Ronne and Ross Ice Shelves), as well as several...

New Sea Level Threat Created From Changing Antarctic Winds
2014-07-07 03:55:30

Australian Research Council's Centre of Excellence for Climate System Science New research shows projected changes in the winds circling the Antarctic may accelerate global sea level rise significantly more than previously estimated. Changes to Antarctic winds have already been linked to southern Australia’s drying climate but now it appears they may also have a profound impact on warming ocean temperatures under the ice shelves along the coastline of West and East Antarctic....

Greenland Ice Sheet Collapse Linked To Sea Level Rise 400,000 Years Ago: Study
2014-06-26 03:26:40

Oregon State University A new study suggests that a warming period more than 400,000 years ago pushed the Greenland ice sheet past its stability threshold, resulting in a nearly complete deglaciation of southern Greenland and raising global sea levels some 4-6 meters. The study is one of the first to zero in on how the vast Greenland ice sheet responded to warmer temperatures during that period, which were caused by changes in the Earth's orbit around the sun. Results of the study,...

Analyzing The Role Of The Ocean In Greenland Ice Sheet Melting
2014-06-24 06:51:19

redOrbit Staff & Wire Reports - Your Universe Online Ice loss from the Greenland Ice Sheet has increased four-fold over the past four decades, and while warmer atmospheric conditions are to blame for increased melting at the glacier’s surface, scientists now report that oceans play a vital role in how quickly the ice sheet will melt and how much total mass will be lost. According to researchers from the Woods Hole Oceanographic Institution (WHOI) and the University of Oregon,...

greenland Petermann Glacier
2014-06-16 04:01:50

redOrbit Staff & Wire Reports - Your Universe Online Newly discovered massive blocks of ice located underneath the ice of Greenland could help scientists learn more about the behavior of ice sheets and how they will respond to global warming, according to research appearing in the latest edition of Nature Geoscience. Lead author Robin Bell, a geophysicist at Columbia University's Lamont-Doherty Earth Observatory, and her colleagues used ice-penetrating radar to discover the ragged...

West Antarctica's Thwaites Glacier Is Melting Due To Geothermal Heat
2014-06-10 10:18:21

Gerard LeBlond for redorbit.com - Your Universe Online Researchers from the Institute for Geophysics at The University of Texas at Austin (UTIG) have discovered that Thwaites Glacier is being eroded by the ocean, as well as being melted from geothermal heat. Their findings are published in the current edition of the Proceedings of the National Academy of Sciences (PNAS). Accurate information from beneath the West Antarctic Ice Sheet has previously been inaccessible, but new findings of...

explaining the Last Glacial Maximum
2014-06-03 05:48:44

redOrbit Staff & Wire Reports - Your Universe Online A team of MIT scientists has turned to the Southern Ocean in search of an explanation for the Last Glacial Maximum (LGM), a period in the Earth's climate history during which the northern continents were covered by ice sheets, according to new research appearing in the Proceedings of the National Academy of Sciences. Plankton fossils in deep-sea sediments contain chemical traces that reveal rearranged ocean water masses, as well...

NASA IceBridge Wraps Up Arctic Field Campaign
2014-05-29 03:43:26

By George Hale, NASA Starting With Sea Ice IceBridge's campaign began on Mar. 10 when NASA's P-3 research aircraft left Wallops for Thule. For the first part of the campaign, researchers studied Arctic sea ice from Thule and Fairbanks, Alaska. Early in each campaign IceBridge spends a week in Alaska to survey sea ice north of Alaska. In addition, researchers study sea ice conditions across the entire Arctic Basin traveling from Thule to Fairbanks and back. IceBridge's sea ice...

Antarctic Ice Sheet Became Unstable At The End Of The Last Ice Age
2014-05-29 05:20:26

redOrbit Staff & Wire Reports - Your Universe Online The Antarctic Ice Sheet started melting approximately 5,000 years earlier than previously believed following the last ice age, according to new research appearing in this week’s edition of the journal Nature. The study, which comes in the wake of research suggesting that destabilization of some of the West Antarctic Ice Sheet has already begun, also said that the shrinkage of the ice sheet accelerated and caused rapid sea level...

Buried Fossil Soils Found To Be Rich In Carbon
2014-05-26 03:40:43

By Terry Devitt, University of Wisconsin-Madison Soils that formed on the Earth’s surface thousands of years ago and that are now deeply buried features of vanished landscapes have been found to be rich in carbon, adding a new dimension to our planet’s carbon cycle. The finding, reported today (May 25, 2014) in the journal Nature Geoscience, is significant as it suggests that deep soils can contain long-buried stocks of organic carbon which could, through erosion, agriculture,...

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...
