antarctic sea ice extent
2014-07-23 02:00:24

European Geosciences Union (EGU) New research suggests that Antarctic sea ice may not be expanding as fast as previously thought. A team of scientists say much of the increase measured for Southern Hemisphere sea ice could be due to a processing error in the satellite data. The findings were published July 22 in The Cryosphere, a journal of the European Geosciences Union (EGU). Arctic sea ice is retreating at a dramatic rate. In contrast, satellite observations suggest that sea ice...

Scientists Tracking Breakup Of Arctic Summer Sea Ice
2014-07-17 03:27:40

By Hannah Hickey, University of Washington As sea ice begins to melt back toward its late September minimum, it is being watched as never before. Scientists have put sensors on and under ice in the Beaufort Sea for an unprecedented campaign to monitor the summer melt. The international effort hopes to figure out the physics of the ice edge in order to better understand and predict open water in Arctic seas. "This has never been done at this level, over such a large area and for such...

Siberia Yamal Peninsula
2014-07-17 10:01:06

Joshua Garrett for redOrbit.com - Your Universe Online What could cause an 80 meter hole to form somewhere in northern Siberia? A meteorite strike? Aliens? Cthulhu? Researchers all over the world are scratching their heads over this one, as no one seems to have an answer they are 100 percent sure of. Reported by the Siberian Times, this giant hole of unknown depth appeared rather suddenly in the Yamal Peninsula, which is said to translate as “end of the world,” giving the whole...

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

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...

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...
