April Flowers for redOrbit.com - Your Universe Online An international team of scientists, led by Julie Brigham-Grette of the University of Amherst, has analyzed the longest continental sediment core ever collected in the Arctic to provide “absolutely new knowledge” of Arctic climate from 2.2 million to 3.6 million years ago. "While existing geologic records from the Arctic contain important hints about this time period, what we are presenting is the most continuous archive...

Iceberg Production Modeled For Greenland Glaciers
2013-05-09 05:59:32

April Flowers for redOrbit.com - Your Universe Online Climate change impacts on the surface of the Greenland Ice Sheet have been widely studied. An understanding, however, of the key processes in iceberg production has eluded researchers for a long time. A new study, led by the Universite Libre de Bruxelles, presents a sophisticated computer model that provides fresh insight into the impact of climate change on the production of icebergs by Greenland glaciers. The model also demonstrates...

NASA's Arctic IceBridge Campaign Closes With Much Success
2013-04-30 14:14:59

Lee Rannals for redOrbit.com — Your Universe Online NASA said its Operation IceBridge team has finished up another successful campaign to continue collecting data of Arctic ice measurements. IceBridge was started in 2009 to help continue and expand a dataset started by NASA's Ice, Cloud and Land Elevation Satellite (ICESat) in 2003. During this year's campaign, the team measured sea ice, mapped sub-ice bedrock and gathered data on Greenland's glaciers by flying science missions...

1000-year Antarctic Peninsula climate reconstruction A new 1000-year Antarctic Peninsula climate reconstruction shows that summer ice melting has intensified almost ten-fold, and mostly since the mid 20th Century. Summer ice melt affects the stability of Antarctic ice shelves and glaciers. The research, published this week in the journal Nature Geoscience, adds new knowledge to the international effort that is required to understand the causes of environmental change in Antarctica and...

Antarctic Glacial Melt May Be Natural
2013-04-15 11:05:27

Brett Smith for redOrbit.com - Your Universe Online As the debate over climate change continues, so does the publication of studies that support or challenge the notion that human activity is the main driver of rising temperatures. According to a new study in“¯Nature Geoscience, the dramatic thinning of glaciers in Western Antarctica is due to natural variation, and cannot be attributed directly to carbon emissions. "If we could look back at this region of Antarctica in...

Researchers Predict Sea Ice-Free Arctic Summers By 2050
2013-04-13 08:18:46

April Flowers for redOrbit.com — Your Universe Online The question of ice-free summers in the Arctic, for most scientists, is not "if," but "when." A new study by two National Oceanic and Atmospheric Administration (NOAA) scientists says that "when" is coming sooner than many thought. Already, the Arctic has experienced a loss of thick, multi-year ice, with last September´s extent being less than half the average of 1979-2000. The scientists, James Overland...

Antarctic Ice Flow Critical To Health Of The Planet
2013-04-10 10:43:29

April Flowers for redOrbit.com - Your Universe Online "Go with the flow" has been a standard, if somewhat glib, piece of nearly universally applicable advice for a long time — and never more so than now. Shujie Wang, a geography doctoral student at the University of Cincinnati's McMicken College of Arts & Sciences, recently led a team of researchers who discovered that the best way to monitor the environmental health of the Antarctic is just to go with the flow. The ice...

Peruvian Ice Cores Reveal History Of Earth's Tropical Climate
2013-04-05 13:11:38

April Flowers for redOrbit.com - Your Universe Online Earth's tropical climate history has been revealed in unprecedented detail — year by year, for almost 1,800 years — by two annually dated ice cores drawn from the tropical Peruvian Andes. In 2003, a research team led by Ohio State University retrieved core samples from a Peruvian ice cap. They noticed some startling similarities to ice cores they had gathered from Tibet and the Himalayas. Even though the cores were taken...

Greenland's 2012 Record Ice Melt Due To Thin Cloud Cover
2013-04-04 11:15:46

April Flowers for redOrbit.com - Your Universe Online Global sea levels would rise by 24 feet if the sheet of ice covering Greenland were to melt in its entirety tomorrow. But it is very unlikely that nearly two million cubic miles of ice will wash into the ocean overnight. Researchers have been tracking increasing melt rates since 1979. Last summer the melt was so extensive that ice core records show similar events only about once every 150 years over the last four millennia. "In...

Arctic Ice Cover Continues To Shrink
2013-04-04 08:52:02

[ Watch the Video: An Interesting Year for Arctic Sea Ice ] April Flowers for redOrbit.com - Your Universe Online The Arctic Ocean's ice cover shrank to its lowest extent on record last September at the end of the northern hemisphere summer. This continues a long-term trend diminishing the ice to about half the size of the average summertime extent from 1979 to 2000. The sea ice refreezes during the cold and dark Arctic winter, achieving its maximum extent usually in late February or...

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...
