University of Innsbruck Between 1902 and 2009, melting glaciers contributed 11 cm to sea level rise. They were therefore the most important cause of sea level rise. This is the result of a new assessment by scientists of the University of Innsbruck. They numerically modeled the changes of each of the world’s 300 000 glaciers. Until 2100, glaciers could lead to an additional 22 cm of sea level rise. Since 1900 the global sea level has risen by approximately 20 cm. Melting glaciers are...
April Flowers for redOrbit.com - Your Universe Online There are almost as many global climate models as there are climate scientists. Even with all of these models, however, it's very difficult to pin down how warming temperatures globally will affect any specific region. A research team from The City College of New York and the University of Liege, Belgium, and supported by the National Science Foundation (NSF), have made the "global local" using the output of three global models and...
ARC Centre of Excellence for Coral Reef Studies Big fish that have grown up in marine reserves don’t seem to know enough to avoid fishers armed with spear guns waiting outside the reserve. The latest research by an Australian team working in the Philippines into the effects of marine reserves has found there is an unexpected windfall awaiting fishers who obey the rules and respect reserve boundaries – in the form of big, innocent fish wandering out of the reserve. “There are...
The terms “gas” and “sea” for many will invoke associations of reserves, business, and a lot of money. Whatever the association, most of the efforts in Israel’s energy field are being directed at gas buried deep under the Mediterranean seabed. Now a new geophysical study, the first of its kind in Israel, has uncovered a system of active gas springs in the Haifa Bay seabed, at relatively shallow depths, only a few dozen meters below the surface. The study, published in the journal...
TAOS, N.M., Nov. 13, 2012 /PRNewswire/ -- The poster was created to honor the 50(th) Anniversary of the first five American mountaineers to reach the Everest's summit in May 1963, and the entire expedition that supported that historic effort. The poster, created by artist Elizabeth Mercuri, is being released in a numbered, Limited First Edition of only 250, and is available exclusively on the website of the Himalayan Stove Project http://www.himalayanstoveproject.org. The poster...
University of Hawaii ‑ SOEST Scientists from the University of Hawaii at Manoa (UHM) published a study today in Nature Climate Change showing that besides marine inundation (flooding), low-lying coastal areas may also be vulnerable to "groundwater inundation," a factor largely unrecognized in earlier predictions on the effects of sea level rise (SLR). Previous research has predicted that by the end of the century, sea level may rise 1 meter. Kolja Rotzoll, Postdoctoral Researcher at the...
redOrbit Staff & Wire Reports - Your Universe Online While global warming has caused extensive melting of sea ice in the Arctic region in recent years, the opposite phenomenon has been occurring in Antarctica, and now experts believe they've discovered the reason why. In a report released Sunday, a team of scientists revealed that shifting wind patterns surrounding the southernmost continent have resulted in slight increase in regional sea ice. That conclusion comes following an...
April Flowers for redOrbit.com – Your Universe Online When toxic seaweed threatens the health of coral, what does the coral do? It calls for help, of course. A new study, published in Science, reveals that corals under attack send signals to fish "bodyguards." The fish respond quickly, moving in to trim back the toxic alga that can kill the coral if not removed in a timely manner. A team from the Georgia Institute of Technology has found evidence that these mutualistic fish respond to...
ESA The first plane to reach Antarctic research base Concordia in nine months landed yesterday, bringing fresh food and replacements for the crew that spent winter in one of the most isolated places on Earth. Summer has definitely arrived. Concordia research station in Antarctica is a place of extremes. In winter, no sunlight is seen for almost four months and the typical crew of 12-15 live in complete isolation. In summer, the Sun stays above the horizon and over 50 scientists flock to...
Rapid advances in the new and developing field of restoration sedimentology will be needed to protect the world's river deltas from an array of threats, Indiana University Bloomington geologist Douglas A. Edmonds writes in the journal Nature Geoscience. The commentary, published this week in the November issue, addresses the fact that land is disappearing from river deltas at alarming rates. And deltas are extraordinarily important: They are ecologically rich and productive, and they are...

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...
