Climate In Arctic More Vulnerable Than Thought
2012-06-25 10:10:11

First analyses of the longest sediment core ever collected on land in the terrestrial Arctic provide documentation that intense warm intervals, warmer than scientists thought possible, occurred there over the past 2.8 million years First analyses of the longest sediment core ever collected on land in the terrestrial Arctic, published this week in Science, provide documentation that intense warm intervals, warmer than scientists thought possible, occurred there over the past 2.8 million...

Deglaciation Data Opens Door For Earlier First Americans Migration
2012-06-25 04:06:21

A new study of lake sediment cores from Sanak Island in the western Gulf of Alaska suggests that deglaciation there from the last Ice Age took place as much as 1,500 to 2,000 years earlier than previously thought, opening the door for earlier coastal migration models for the Americas. The Sanak Island Biocomplexity Project, funded by the National Science Foundation, also concluded that the maximum thickness of the ice sheet in the Sanak Island region during the last glacial maximum was 70...

Elephant Seals Assist In Ice Shelf Research

Brett Smith for redOrbit.com In the Bizarro world of climate change crusaders, what is good is bad, what is up is down, and what is hot is cold. New research published this week in the American Geophysical Union journal Geophysical Research Letters asserts that an Antarctic ice shelf melting slower than expected is good news for those of us who dislike massive flooding – but bad news for those sounding the alarm against global warming. During the two-year study, researchers led...

Ancient Antarctica Was A Completely Different Place
2012-06-18 04:13:26

A new university-led study with NASA participation finds ancient Antarctica was much warmer and wetter than previously suspected. The climate was suitable to support substantial vegetation -- including stunted trees -- along the edges of the frozen continent. The team of scientists involved in the study, published online June 17 in Nature Geoscience, was led by Sarah J. Feakins of the University of Southern California in Los Angeles, and included researchers from NASA's Jet Propulsion...

Eemian Period Is A Poor Analogue For Current Climate Change
2012-06-15 04:34:14

The Eemian interglacial period that began some 125,000 years ago is often used as a model for contemporary climate change. In the international journal “Geophysical Research Letters” scientists from Mainz, Kiel and Potsdam (Germany) now present evidence that the Eemian differed in essential details from modern climatic conditions. Joint press release of the Academy of the Sciences and the Literature Mainz and the GEOMAR | Helmholtz Centre for Ocean Research Kiel. To address...

Derek Walter for redOrbit.com A team of Harvard researchers has developed a superior method for keeping metal surfaces free of ice and frost. It´s a difficult task, but one that could have substantial implications for metal surfaces used in wind turbines, aircraft, refrigeration systems, marine vessels and the construction industry. Airplane wings, railings, and other fabrication parts are just a sample of how often metal is used throughout the world in most of the largest...

[ Watch the Video ] redOrbit Staff & Wire Reports NASA officials announced on Thursday that an expedition they sponsored had uncovered a massive bloom of phytoplankton in the ice-capped waters of the Arctic Ocean -- a discovery which the U.S. space agency has called "as dramatic and unexpected as finding a rainforest in the middle of a desert." The findings, which came as part of Impacts of Climate on EcoSystems and Chemistry of the Arctic Pacific Environment (ICESCAPE)...

80-Year-Old Photos Aid In Greenland Ice Melt Study
2012-05-30 09:11:47

Researchers from Denmark´s University of Copenhagen have gained new insight into the loss of ice mass in Greenland´s glaciers thanks to a chance discovery of 80-year-old photo plates discovered in a Danish basement. It is often difficult for scientists to assess the scale and speed of Arctic ice melt, but the extremely rare photos provide them with a more accurate picture. Greenland´s ice was rapidly melting in the 1930s, followed by a cooling period in middle of the 20th...

Using statistical tool, researchers are able to track where the melting that contributes to sea level rise happens It was used to help Apollo astronauts navigate in space, and has since been applied to problems as diverse as economics and weather forecasting, but Harvard scientists are now using a powerful statistical tool to not only track sea level rise over time, but to determine where the water causing the rise is coming from. As described in an April 23 paper in the Proceedings 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...
