New Study Sheds Light On Little Ice Age
2012-01-30 15:44:41

University of Colorado researchers report that they have answered some questions surrounding Earth's Little Ice Age, which started between A.D. 1275 and 1300, and lasted into the late 19th century. According to the new study, the Little Ice Age was triggered by repeated, explosive volcanism and sustained by a self-perpetuating sea ice-ocean feedback system in the North Atlantic Ocean. Professor Gifford Miller, who led the study, said the team's evidence from radiocarbon dates from dead...

University of Miami study offers new geochemical clues to understand conditions just prior to major climatic event In a study published in the journal Geology, scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science suggest that the large changes in the carbon isotopic composition of carbonates which occurred prior to the major climatic event more than 500 million years ago, known as 'Snowball Earth,' are unrelated to worldwide glacial events. "Our...

Most people are aware of the notoriously dangerous driving conditions that occur on icy roads during the winter, but fewer know about the hazards of participating in winter recreation such as ice skating, fishing and hockey, or simply walking on ice. All Hands Fire Equipment offers some important guidelines that should be remembered when dealing with ice during outdoor recreation in the winter months. (PRWEB) January 23, 2012 The big question that comes up regarding winter sports is...

Glacier Cores From Eastern European Alps May Yield New Climate Clues
2012-01-10 05:41:00

Researchers are beginning their analysis of what are probably the first successful ice cores drilled to bedrock from a glacier in the eastern European Alps. With luck, that analysis will yield a record of past climate and environmental changes in the region for several centuries, and perhaps even covering the last 1,000 years.  Scientists also hope that the core contains the remnants of early human activity in the region, such as the atmospheric byproducts of smelting metals. The...

Unprecedented levels of greenhouse gases in the Earth's atmosphere are disrupting normal patterns of glaciation, according to a study co-authored by a University of Florida researcher and published online Jan. 8 in Nature Geoscience. The Earth's current warm period that began about 11,000 years ago should give way to another ice age within about 1,500 years, according to accepted astronomical models. However, current levels of carbon dioxide are trapping too much heat in the atmosphere to...

Image 1 - Russian River Runoff Freshening Beaufort Sea
2012-01-05 13:33:42

According to findings published in the journal Nature, Russian river water was diverted hundreds of miles to a different part of the ocean in response to a decades-long shift in atmospheric pressure. Researchers found that a low pressure pattern created by the Arctic Oscillation from 2005 to 2008 drew Russian river water away from the Eurasian Basin and into the Beaufort Sea. This diversion resulted in adding 10 feet of freshwater over the central part of the Beaufort Sea. "Knowing...

SMOS Versatility Offers Sea Ice Mapping
2011-12-21 04:27:20

ESA´s SMOS mission is proving to be extremely versatile. Not only does this pioneering satellite offer crucial data on soil moisture and ocean salinity, but it can also map the thickness of ice floating in the polar seas. The Soil Moisture and Ocean Salinity (SMOS) satellite carries an innovative passive microwave radiometer to capture images of ℠brightness temperature´. These images correspond to microwave radiation emitted from Earth´s surface and can be related to...

Climate change effects to be monitored with new fiber-optic distributed temperature sensing Half-mile long thermometers have been dropped through the Ross Ice Shelf in Antarctica that will give the world relevant data on sea and ice temperatures for tracking climate change and its effect on the glacial ice surrounding the continent. The study based at the University of Nevada, Reno is funded by the National Science Foundation's Office of Polar Programs and other NSF grants. "This...

Image 1 - Antarctic Expedition Checks CryoSat Data
2011-12-10 04:41:07

Next week marks 100 years since Roald Amundsen reached the South Pole. As a team of scientists brave the Antarctic to validate data from ESA´s CryoSat mission, it´s hard to imagine what these first intrepid explorers would have thought of today´s advances in polar science. The remote and vast expanse of the Antarctic is arguably the most hostile environment on Earth — infamously claiming the lives of Captain Robert Scott and his party all those years ago in their fated...

French Alps Glaciers Have Decreased 26% In 40 Years
2011-12-08 06:18:02

A new study has found that the glaciers in the French Alps have lost a quarter of their area in the past 40 years. Marie Gardent, from the University of Savoie, and colleagues assessed about 600 glaciers in broad areas incorporating the Ecrins, Belledonne, Vanoise, Ubaye and Grande Rousse Arves massifs. The team used map archives, past satellite imagery and aerial photographs to assess the areas.  Manual inspection was used to ensure that the automatic delineation methods used in...

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...
