Antarctic Permafrost Melting Faster Than Previously Thought
2013-07-24 17:51:21

Lee Rannals for redOrbit.com - Your Universe Online Scientists reported in the journal Scientific Reports that permafrost in a section of Antarctica is melting faster than expected. Data from Garwood Valley in the McMurdo Dry Valleys region of Antarctica has shown that melt rates accelerated consistently from 2001 to 2012, rising to about ten times the valley's historical average for the present geologic epoch. Scientists previously thought the region's ground ice to be in equilibrium,...

Mars Water May Have Come From Orographic Precipitation
2013-07-24 06:49:15

redOrbit Staff & Wire Reports - Your Universe Online Orographic precipitation, or rain and snow that falls when moist prevailing winds are forced upwards by mountain ridges, appears to have played a role in the formation of some Martian valleys, researchers from Brown University in Rhode Island report in a recently published study. While the valley networks that cover the surface of the Red Planet provide strong evidence water once flowed on Mars, the source of that ancient water...

Fly Through Valles Marineris On Mars
2013-07-15 11:38:00

ESA [ Watch The Video Fly-through movie of Hebes Chasma ] Glide through part of the largest canyon on Mars, Valles Marineris, in this stunning color movie from ESA's Mars Express. Valles Marineris is not just the largest canyon on Mars, but at 4000 km long, 200 km wide and 10 km deep it is the largest in the entire Solar System. The movie focuses on an enclosed 8 km-deep trough in the northern most part of Valles Marineris, called Hebes Chasma. The movie glides over impact...

Meteor Impact Crater Found Beneath Iowa Town
2013-07-11 04:39:36

Lee Rannals for redOrbit.com - Your Universe Online A meteor crater from 470-million-years-ago lies buried several hundred feet beneath the town of Decorah, Iowa, according to an airborne geophysical survey reported in EARTH Magazine. Geologists first hypothesized the crater's existence while examining cuttings from water wells drilled near the town. During this examination they discovered evidence of a previously unknown shale deposit that was nearly a perfect circle, roughly 3.4 miles...

Mars Express Shows Of The Red Planet's Flood History
2013-06-06 13:39:33

Lee Rannals for redOrbit.com — Your Universe Online The European Space Agency (ESA) said that a new image taken by its Mars Express orbiter shows off flood events that took place on the Red Planet. The flooding events that took place at Kasei Valles carved out an impressive channel system on Mars that stretches nearly 580,000 square miles. The mosaic taken by Mars Express comprises of 67 images taken with the spacecraft's high-resolution stereo camera. Kasei Valles is one of...

Pebbles, Sand In Martian River Network Show Signs Of Ancient Water
2013-06-05 09:19:44

April Flowers for redOrbit.com - Your Universe Online The most convincing evidence yet that the frigid deserts of Mars were once a habitable environment crossed by flowing water are presented by pebbles and sand scattered near an ancient Martian river network. The findings of this study, led by scientists at NASA´s Mars Science Laboratory mission, were published in the journal Science. The research team says that the discovery of sand grains and small stones that bear the telltale...

Researchers Suprised By Arctic Resiliency In Carbon Storage
2013-05-17 08:15:10

April Flowers for redOrbit.com - Your Universe Online Certain assumptions were made by UC Santa Barbara doctoral student Seeta Sistla and her adviser, environmental studies professor Josh Schimel, when they traveled north recently to study the effects of long-term warming on the carbon storage of the Arctic. "We expected that because of the long-term warming, we would have lost carbon stored in the soil to the atmosphere," said Schimel. He explained that the gradual warming would...

Underground Explosions Responsible For Pits Inside Twin Craters On Mars
2013-04-11 11:32:25

ESA Dramatic underground explosions, perhaps involving ice, are responsible for the pits inside these two large martian impact craters, imaged by ESA´s Mars Express on 4 January. The ℠twin´ craters are in the Thaumasia Planum region, a large plateau that lies immediately to the south of Valles Marineris, the largest canyon in the Solar System. The northernmost (right) large crater in this scene was officially given the name Arima in early 2012, but the southernmost...

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....
