Arctic Is Changing Before Our Eyes
2012-12-07 05:07:03

Lee Rannals for redOrbit.com - Your Universe Online The 2012 Arctic Report Card was released on Thursday, showing a record low snow coverage and record low sea ice extent. The report card calls on the expertise of 140 scientists from 15 countries to summarize the state of the Arctic. Martin Jeffries of the Office of Naval Research warns that "if we are not already there, we're clearly on the verge of seeing a new Arctic." The report shows a longer growing season with greener...

Snow Cover Worldwide Is At Record Lows
2012-12-04 07:25:37

April Flowers for redOrbit.com - Your Universe Online A new European Space Agency (ESA) study of snow cover observed by satellites reveals record lows in Eurasia for June each year since 2008. Three of the past five years have seen record low cover in North America, as well. Since satellite observations began some 45 years ago, this is the lowest June snow extent on record. Snow cover in June is falling faster than climate models have predicted. It is even disappearing faster than...

Ice Sheet Loss At Both Poles Is Clearly Increasing
2012-11-30 08:10:18

April Flowers for redOrbit.com - Your Universe Online In a new study that ends 20 years of uncertainty, an international team of satellite experts have produced the most accurate assessment of ice losses from Antarctica and Greenland to date. Published in the journal Science, the landmark study shows that the melting of the Antarctic and Greenland ice sheets has contributed 11.1 millimeters to global sea levels since 1992, amounting to one fifth of all sea level rise over the survey...

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...

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...
