The Health Of Antarctic Glaciers Relies On Salt Intake: NASA
2013-12-06 10:19:26

April Flowers for redOrbit.com - Your Universe Online An intriguing link between sea ice conditions and the melting rate of Totten Glacier, the glacier in East Antarctica that discharges the most ice into the ocean, has been found by a NASA-led study. The discovery, published in Nature Communications, involves cold, extra salty water—brine—that forms within openings in sea ice. The findings will add to our understanding of how ice sheets interact with the ocean, and may improve our...

Scientists Find Rapid Warming Threatens Rich Seafloor Communities
2013-12-04 10:09:25

University of Hawaii at Manoa Deep inside the dramatic subpolar fjords of Antarctica, researchers from the University of Hawai'i at Mānoa have discovered an unexpected abundance and diversity at the seafloor. During a recent expedition, UH scientists for the first time studied the seafloor communities of glacier dominated fjords along the west Antarctic Peninsula, a region undergoing very rapid climate warming. The scientists expected to find impoverished seafloor communities highly...

Airborne Radar Looks Through Thick Ice During NASA Polar Campaigns
2013-12-03 15:23:42

NASA The bedrock hidden beneath the thick ice sheets covering Greenland and Antarctica has intrigued researchers for years. Scientists are interested in how the shape of this hidden terrain affects how ice moves -- a key factor in making predictions about the future of these massive ice reservoirs and their contribution to sea level rise in a changing climate. NASA has been monitoring Antarctic and Arctic ice since 2009 with the Operation IceBridge airborne mission. Although the primary...

Warm Water Causes Arctic Glaciers To Sizzle As They Melt
2013-11-28 06:11:28

[ Watch the Video: Melting Glacial Ice Has Its Own Sound ] April Flowers for redOrbit.com - Your Universe Online One of the most prominent sounds of a warming planet has been recorded and identified by scientists at the University of Alaska: the sizzle of glacial ice as it melts into the sea. Trapped air bubbles squirting out of the disappearing ice causes a noise that might provide clues to the rate of glacier melt and help researchers better monitor the fast-changing polar...

Greenland Ice Sheet Is Hiding Subglacial Lakes
2013-11-28 04:29:14

redOrbit Staff & Wire Reports - Your Universe Online Researchers have discovered a pair of subglacial lakes discovered over 800 meters beneath the Greenland Ice Sheet – the first ever to be discovered in the island nation, according to research appearing in the latest edition of the journal Geophysical Research Letters. The two lakes are reportedly between eight and 10 square kilometers in surface area, but might have been up to three times larger than their current size at one...

Arctic Fossil Record Traces Greenland Ice Sheet's Past
2013-11-23 05:24:05

April Flowers for redOrbit.com - Your Universe Online There have been many studies telling us how small the Greenland ice sheet is today. A new study, published in the journal Geology, reveals that the ice sheet was actually smaller between 3,000 and 5,000 years ago. Surprisingly, the sheet was as small during this period as it has ever been in recent history. The international research team used a new technique they developed for interpreting the Arctic fossil record. “What’s...

Predictions of sea level rise could become more accurate, thanks to new insight into how glacier movement is affected by melting ice in summer Predictions of sea level rise could become more accurate, thanks to new insight into how glacier movement is affected by melting ice in summer. Studies of the Greenland ice sheet, including during a record warm summer, are helping scientists better understand how summer conditions affect its flow. This is important for predicting the future...

Moraine Research May Alter Thinking On Climate’s Effect On Glaciers
2013-11-20 07:58:56

redOrbit Staff & Wire Reports - Your Universe Online A Dartmouth College-led study published in the latest edition of the journal Quaternary Geochronology describes a newly discovered, more accurate method to date the soil and rock debris left behind by high altitude tropical glaciers. The research could alter pre-existing interpretations of how climate change affected equatorial ice masses, the study authors explained in a statement Tuesday. Currently, scientists use a variety of...

Algae Reveal History Of Arctic Sea Ice
2013-11-19 12:15:57

Brett Smith for redOrbit.com - Your Universe Online An international team of researchers has developed a novel method for tracking changes in Arctic sea ice through the analysis of growth layers of seafloor algae, according to their report in the Proceedings of the National Academy of Sciences. The study found that the algae Clathromorphum compactum accumulates a calcite crust as it grows and changes to this crust over time can be analyzed to reveal historical conditions of the...

Glacier ‘Tiger Stripes’ Slowing Down Ice Flow In Antarctica
2013-11-08 17:21:54

Lee Rannals for redOrbit.com – Your Universe Online Researchers writing online in the journal Science say they have found narrow stripes of dirt and rock underneath Antarctic glaciers create friction zones that slow the flow of ice toward the sea. These ribs, or “tiger stripes,” provide friction that hinders the glaciers from slipping along the underlying bed of rock and sediment. Understanding how these regions form and subside could help scientists know more about the flow of...

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...
