Pasquali Realty Group is reminding homeowners that there is still time to take precautions to protect their household plumbing and water meter from freezing. Burke, VA (PRWEB) October 16, 2014 Homeowners sometimes need to deal with frozen pipes during cold stretches during the winter months. Pasquali Realty Group, a Northern Virginia real estate company suggests the following tips to protect their household plumbing from freezing: — Allow room heat to freely circulate around meters and...

WASHINGTON, Oct. 16, 2014 /PRNewswire-USNewswire/ -- NASA is carrying out its sixth consecutive year of Operation IceBridge research flights over Antarctica to study changes in the continent's ice sheet, glaciers and sea ice. This year's airborne campaign, which began its first flight Thursday morning, will revisit a section of the Antarctic ice sheet that recently was found to be in irreversible decline. http://photos.prnewswire.com/prnvar/20081007/38461LOGO For the next several...

Antarctic Sea Ice Reached New Record High Extent This Year
2014-10-10 03:41:14

[ Watch The Video: The Arctic And The Antarctic Respond In Opposite Ways ] Provided by Kate Ramsayer, NASA Sea ice surrounding Antarctica reached a new record high extent this year, covering more of the southern oceans than it has since scientists began a long-term satellite record to map sea ice extent in the late 1970s. The upward trend in the Antarctic, however, is only about a third of the magnitude of the rapid loss of sea ice in the Arctic Ocean. The new Antarctic sea ice...

ARC Centre of Excellence for Climate System Science Current changes in the ocean around Antarctica are disturbingly close to conditions 14,000 years ago that new research shows may have led to the rapid melting of Antarctic ice and an abrupt 3-4 meter rise in global sea level. The research published in Nature Communications found that in the past, when ocean temperatures around Antarctica became more layered - with a warm layer of water below a cold surface layer - ice sheets and...

Flights Rerouted Due To 35,000 Walruses Massed On Alaskan Beach
2014-10-03 07:47:41

Eric Hopton for redOrbit.com – Your Universe Online A dense mass of Pacific walruses, estimated to be 35,000 strong, has gathered on a beach in northwest Alaska, approximately five miles north of Point Lay. Scientists believe this unprecedented number of animals has been driven to shore by a lack of sea ice. The UK’s Guardian newspaper reported today that the United States Federal Aviation Authority (FAA) has rerouted flights in the area in order to reduce the risk of planes causing a...

George Hale, NASA's Goddard Space Flight Center Thanks in part to support from NASA and the National Science Foundation, scientists have produced the first-ever detailed maps of bedrock beneath glaciers in Greenland and Antarctica. This new data will help researchers better project future changes to glaciers and ice sheets, and ultimately, sea level. Researchers at the Center for Remote Sensing of Ice Sheets, or CReSIS, at the University of Kansas in Lawrence, Kansas, recently built...

Greenland Ice Sheet
2014-09-30 04:38:53

Brett Smith for redOrbit.com - Your Universe Online Prevailing models from the melting of the Greenland ice sheet have made the calculation that the ice sheet sits atop hard bedrock. A new study from a team of British and American scientists has thrown out that assumption, however, and found that the ice sheet may be melting faster than previously thought. Published in the journal Nature Communications, the team’s report is based on the calculation, derived from ground surveys,...

European Space Agency Although not designed to map changes in Earth’s gravity over time, ESA’s extraordinary satellite has shown that the ice lost from West Antarctica over the last few years has left its signature. More than doubling its planned life in orbit, GOCE spent four years measuring Earth’s gravity in unprecedented detail. Scientists are now armed with the most accurate gravity model ever produced. This is leading to a much better understanding of many facets of our...

Antifreeze Proteins Prevent Freezing And Melting For Antarctic Fish
2014-09-24 03:04:19

University of Illinois at Urbana-Champaign Antarctic fish that manufacture their own "antifreeze" proteins to survive in the icy Southern Ocean also suffer an unfortunate side effect, researchers report: The protein-bound ice crystals that accumulate inside their bodies resist melting even when temperatures warm. The finding is reported in the Proceedings of the National Academy of Sciences. "We discovered what appears to be an undesirable consequence of the evolution of antifreeze...

Sea Ice Helps Remove CO2 From The Atmosphere
2014-09-23 03:30:21

University of Southern Denmark Climate change is a fact, and most of the warming is caused by human activity. The Arctic is now so warm that the extent of sea ice has decreased by about 30 pct. in summer and in winter, sea ice is getting thinner. New research has shown that sea ice removes CO2 from the atmosphere. If Arctic sea ice is reduced, we may therefore be facing an increase of atmospheric concentration of CO2, researchers warn. Due to global warming, larger and larger areas of...

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...
