April Flowers for redOrbit.com - Your Universe Online When thick ice covered the Arctic during the last ice age, many scientists assumed that the deep currents below the ice that feed the North Atlantic Ocean and help drive the global ocean currents slowed or possibly even stopped. A new study reveals that the deep Arctic Ocean has been churning briskly for the last 35,000 years, through the chill of the last ice age and warmth of modern times. These findings, published in the journal...
U.S. Naval Research Laboratory Geochemistry analysis conducted by the U.S. Naval Research Laboratory of fossil sediment injection structures off the New Zealand coast in February and March reveal no presence of modern day expulsions of methane gas, a potential contributor to global 'greenhouse effect' warming. The main focus of this most recent expedition was to investigate the geological origin of seafloor anomalies discovered during a 2007 marine-life survey on the Chatham Rise....
Brett Smith for redOrbit.com - Your Universe Online Exactly 60 years after Sir Edmund Hillary reached the summit of Mount Everest, Microsoft has unveiled “Everest: Rivers of Ice,” a website designed to virtually bring Earth’s highest peak to laptops and touch screens around the world. Using high-resolution video and photographic panorama content to display the Greater Himalaya region, Rivers of Ice is the result of a collaboration between the Internet Explorer 10 team and...
April Flowers for redOrbit.com - Your Universe Online The public and policymakers alike were caught off guard when Hurricane Sandy hit the east coast of the US last fall. The majority of the destruction came from the storm surge and flooding that followed the storm, leading researchers to pay attention to how climate change and sea-level rise may have played a role in the disaster, and how those same factors may impact the shoreline in the future. Benjamin P. Horton, an associate...
ANN ARBOR, Mich., May 29, 2013 /PRNewswire/ -- SNO(TM) glacier water from Iceland, already rated "purest water on the planet," has chalked up yet another third-party certification, this one from the highly-respected National Sanitation Foundation (NSF). SNO (www.iglacierwonders.com) received NSF's certification, symbolizing it has met NSF's stringent compliance standards assuring consumers this product has undergone extensive product testing and analysis, including a complete...
There is growing recognition that reductions in Arctic sea ice levels will influence patterns of atmospheric circulation both within and beyond the Arctic. New research in the International Journal of Climatology explores the impact of 2007 ice conditions, the second lowest Arctic sea ice extent in the satellite era, on atmospheric circulation and surface temperatures. Two 30-year simulations, one using the sea ice levels of 2007 and another using sea ice levels at the end of the 20th...
Lee Rannals for redOrbit.com - Your Universe Online Ocean data collected over 135 years ago by the crew of the HMS Challenger oceanographic expedition has helped confirm global warming. Researchers from NASA and the University of Tasmania used the data to provide further confirmation that humans have played a part in today's changing global climate. The team combined the ship's measurements of ocean temperatures with modern observations from the international Argo array of ocean...
Lawrence LeBlond for redOrbit.com - Your Universe Online Researchers publishing a paper in the latest issue of the journal Science have found through Antarctic planktonic ice core examinations that the continental ice cap formed more than 33 million years ago. Scientists from the Andalusian Institute of Earth Sciences (IACT), a joint collaboration between the University of Granada and the Spanish National Research Council (CSIC), said the seasonal primary productivity of planktonic...

The dusky pademelon (Thylogale brunii), also known as the dusky wallaby, is a marsupial that can be found on the Kai and Aru islands, Papua New Guinea, and in the Trans Fly savanna and grasslands ecoregion in Papua Province in Indonesia. It prefers a habitat in both arid and tropical savannahs, forests, shrublands, lowlands, and grasslands. This species was named after its discoverer, Cornelis de Bruijn, and was once commonly known as philander, or “friend of man,” and the Aru Island...
Desert greening is made up of any number of methods used to revitalize deserts. So far, only arid and semi-arid desert are meant when using this expression. The icy deserts and other types are considered to be unsuitable. The different methods include landscaping methods to reduce evaporation, erosion, consolidation of topsoil, temperature, sandstorms and more, permaculture in general, planting trees, regeneration of salty, polluted, or degenerated soils, floodwater retention and...
Mammoth Cave National Park is located in the state of Kentucky in the United States. The park holds 52,830 acres of land that was once inhabited by Native Americans. Many mummies and artifacts have been found in Mammoth Cave and surrounding caves to support this. It is thought that first man of European descent to visit the area was John Houchin or Francis Houchin. The legend says that one of the brothers was hunting a wounded bear that entered the cave to hide. The first documented discovery...
Coral reefs are submerged structures consisting of calcium carbonate secreted by corals. Coral reefs are colonies of small animals found in marine waters that enclose few nutrients. The majority of coral reefs are constructed from stony corals, which then consist of polyps that come together in groups. The polyps are like small sea anemones, to which they are very closely related. Unlike the sea anemones, coral polyps secrete hard carbonate exoskeletons which provide support and protections...
Mudflats, or otherwise known as tidal flats, are coastal wetlands that form when mud is left behind by tides or rivers. They’re found in sheltered regions such as bayous, lagoons, estuaries, and bays. Mudflats might be seen geologically as exposed layers of bay mud, a result from the deposition of estuarine silts, marine animal detritus, and clays. The majority of the sediment in a mudflat is within the intertidal zone, therefore the flat is submerged and exposed about twice per day. In...
