An enhanced approach to capturing changes on the Earth's surface via satellite could provide a more accurate account of how ice sheets, river basins and other geographic areas are changing as a result of natural and human factors. In a first application, the technique revealed sharper-than-ever details about Greenland's massive ice sheet, including that the rate at which it is melting might be accelerating more slowly than predicted. Princeton University researchers developed a...

Columbia Glacier Should Stop Retreating By 2020
2012-11-27 08:30:37

April Flowers for redOrbit.com - Your Universe Online Alaska's Columbia Glacier, one of the fastest moving glaciers in the world, will cease to move by approximately 2020, according to a new study from the University of Colorado Boulder. The research team included members from CU-Boulder's Cooperative Institute for Research in Environmental Sciences, Institute of Arctic and Alpine Research, Department of Civil, Environmental, and Architectural Engineering, NASA and the Extreme Ice...

Oil Companies Work In Extreme Conditions
2012-11-26 11:49:18

University of Stavanger The northward shift of Norway's oil industry means it must adjust to temperatures down to -30°C, storms, sleet and snow, and drift ice; and to the blackest night "Try to imagine changing a tyre in freezing weather, snow and darkness," says professor Tore Markeset, a specialist in cold climate technology at the University of Stavanger (UiS). That is his way of visualizing the challenges facing oil companies seeking to produce oil and gas from the far north...

Ocean Currents Helps Predict Arctic Sea Ice
2012-11-21 15:07:41

Lee Rannals for redOrbit.com - Your Universe Online Researchers at MIT have developed a new method for optimally combining models and observations of the Arctic Ocean to accurately simulate the seasonal extent of the ice change and the ocean circulation beneath. The Arctic Ocean freezes each winter to form sheets of sea ice that spread over millions of square miles. This ice then acts as a massive sun visor for the Earth and helps to reflect solar radiation and shield the planet from...

Glaciers Will Continue To Shrink Regardless Of Temperature
2012-11-16 15:50:50

Michael Harper for redOrbit.com — Your Universe Online The Himalayan glaciers are going to continue to shrink, no matter which way the temperatures go, according to new research published in the journal Geophysical Research Letters. Summer Rupper, a geology professor at Brigham Young University, has just returned from her research in the Bhutan region of the Himalayas and has reported findings that nearly 10% of these glaciers will disappear within the next 30 years. She also...

Rising Temperatures Could Lead To Sea Levels Rising Three Feet Or More
2012-11-15 13:56:59

April Flowers for redOrbit.com - Your Universe Online A rapid response between global temperatures and ice volume/sea-level that could lead to sea-levels rising by over 3 feet have been revealed by a new study from the University of Southampton. Global ice-volume variability has been one of the main feedback mechanisms in climate change during the last few million years. This is because of the strong reflective properties of large ice sheets. Scientists reconstruct ice volume...

NASA Studies Antarctic Sea Ice
2012-11-14 19:43:13

Alan McStravick for redOrbit.com — Your Universe Online A new study by NASA and the British Antarctic Survey tries to explain the increase of ice cover in the Antarctic that is seemingly contrary to the effects of climate change that have been witnessed over the previous two decades. In their report, they purport they have the first direct evidence that this increase in sea ice cover is due to changing winds that have had an impact on the changes to Antarctic sea ice drift. The...

Anthropogenic Climate Change Leads To Melting Glaciers And Rising Sea Level
2012-11-14 15:22:41

University of Innsbruck Between 1902 and 2009, melting glaciers contributed 11 cm to sea level rise. They were therefore the most important cause of sea level rise. This is the result of a new assessment by scientists of the University of Innsbruck. They numerically modeled the changes of each of the world´s 300 000 glaciers. Until 2100, glaciers could lead to an additional 22 cm of sea level rise. Since 1900 the global sea level has risen by approximately 20 cm. Melting glaciers...

Winds Responsible For Antarctic Sea Ice Growth
2012-11-12 05:17:56

redOrbit Staff & Wire Reports - Your Universe Online While global warming has caused extensive melting of sea ice in the Arctic region in recent years, the opposite phenomenon has been occurring in Antarctica, and now experts believe they've discovered the reason why. In a report released Sunday, a team of scientists revealed that shifting wind patterns surrounding the southernmost continent have resulted in slight increase in regional sea ice. That conclusion comes following an...

What Triggered Earth's Last Big Freeze
2012-11-06 09:53:08

April Flowers for redOrbit.com - Your Universe Online Climate scientists have long debated whether floodwaters from melting of the Laurentide Ice Sheet flowed northwest into the Arctic first, or east via the Gulf of St. Lawrence to weaken ocean thermohaline circulation and have a frigid effect on global climate. This debate concerning the melt, which ushered in the last major cold episode about 12,900 years ago, has been raging for about 30 years. A research team from the University 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...
