Arctic Lakes Soak Up More Greenhouse Gases Than They Emit: Study
2014-07-18 03:19:15

University of Alaska Fairbanks New University of Alaska Fairbanks research indicates that arctic thermokarst lakes stabilize climate change by storing more greenhouse gases than they emit into the atmosphere. Countering a widely-held view that thawing permafrost accelerates atmospheric warming, a study published this week in the scientific journal Nature suggests arctic thermokarst lakes are 'net climate coolers' when observed over longer, millennial, time scales. "Until now, we've...

Siberia Yamal Peninsula

Joshua Garrett for redOrbit.com - Your Universe Online What could cause an 80 meter hole to form somewhere in northern Siberia? A meteorite strike? Aliens? Cthulhu? Researchers all over the world are scratching their heads over this one, as no one seems to have an answer they are 100 percent sure of. Reported by the Siberian Times, this giant hole of unknown depth appeared rather suddenly in the Yamal Peninsula, which is said to translate as “end of the world,” giving the whole...

Forces Of Martian Nature

ESA The surface of Mars is pocked and scarred with giant impact craters and rocky ridges, as shown in this new image from ESA’s Mars Express that borders the giant Hellas basin in the planet’s southern hemisphere. The Hellas basin, some 2300 km across, is the largest visible impact structure in the Solar System, covering the equivalent of just under half the land area of Brazil. The images presented here were taken on 13 January 2014 by the high-resolution stereo camera on Mars...

Twelvemile Lake permafrost
2014-06-11 06:47:04

April Flowers for redOrbit.com - Your Universe Online Most studies on Arctic permafrost are harbingers of doom. As the sea ice melts, the permafrost is being affected, and releasing large amounts of greenhouse gases such as carbon and methane. These gases will accelerate the process of global warming, creating a vicious cycle. A new study from the US Geological Survey and McGill University, published in Geophysical Research Letters, has revealed a surprise in permafrost research....

New Study Finds That Lava Carved The Giant Valleys Of Mars
2014-05-13 07:17:31

April Flowers for redOrbit.com - Your Universe Online In 1877, Giovanni Schiaparelli of Italy first described what he called "canali" on the surface of Mars. These straight landforms on the Martian equatorial region form a conspicuous net-like system of deep gorges called the Noctis Labyrinthus, which is clearly visible. Noctis Labyrinthus leads into the even larger Valles Marineris canyon, which is 2500 miles long,  125 miles wide and 4 miles deep. Together, these two systems would span...

Chaos Causes Beauty
2014-04-11 10:57:36

ESA Beautiful streamlined islands and narrow gorges were carved by fast-flowing water pounding through a small, plateau region near the southeastern margin of the vast Vallis Marineris canyon system. Images captured on 7 December 2013 by ESA’s Mars Express show the central portion of Osuga Valles, which has a total length of 164 km. It is some 170 km south of Eos Chaos, which lies in the far eastern section of Valles Marineris. Osuga Valles is an outflow channel that emanates from...

Permafrost Thawing Could Accelerate Global Warming
2014-04-08 15:41:51

Kathleen Haughney, Florida State University A team of researchers lead by Florida State University have found new evidence that permafrost thawing is releasing large quantities of greenhouse gases into the atmosphere via plants, which could accelerate warming trends. The research is featured in the newest edition of the Proceedings of the National Academy of Sciences. “We’ve known for a while now that permafrost is thawing,” said Suzanne Hodgkins, the lead author on the paper...

Desert greening
2013-04-25 16:10:03

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...

Theodore Roosevelt National Park
2013-04-18 01:20:13

Theodore Roosevelt National Park is located in western North Dakota in the United States. The park contains 70,446 acres of land that is separated into three distinct badland areas known as the Elkhorn Ranch Unit, the South Unit, and the North Unit. Roosevelt  first visited the area in 1883, while hunting for bison, and is said to have “fallen in love” with the badlands. After investing a large sum of money into the Maltese Cross Ranch, Roosevelt had his own cabin built, which he later...

A drainage divide, water divide, divide, or watershed is the line that separates neighboring drainage basins. In flat country the divide may be invisible (just a notional line on the ground either side of which water starts its journey to different waterways). While, in hilly country, the divide lies along peaks and ridges. Drainage divides are important geographical, and sometimes political boundaries. Roads and railways often follow divides to minimize slopes and marshes and rivers....
