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...

A team of geoscientists from Southwest Research Institute (SwRI) using newly available remote-sensing technology has achieved unprecedented detail in quantifying subtle, long-period changes in the water levels of shallow lakes and ponds in hard-to-reach Arctic wetlands. Analysis comparing time-lapsed, high-resolution satellite imagery of the Ahnewetut Wetlands in Kobuk Valley National Park, Alaska, revealed an accelerated loss of surface water in shallow thaw lakes and ponds over a recent...

Siberia Could Experience Widespread Permafrost Thaw Due To Global Warming
2013-02-23 09:07:48

Lee Rannals for redOrbit.com — Your Universe Online More evidence is pointing to the nightmare scenario that global warming is taking a toll on our planet. Oxford University scientists say that a global temperature rise of 2.7 degrees Fahrenheit could thaw the ground over a large area of Siberia, threatening the release of carbon from soil. If the thawing of Siberia's permafrost occurs, it could see that over 1,000 gigatons of the greenhouse gases carbon dioxide and methane are...

Arctic Permafrost Melt Releasing Carbon Dioxide At Unprecedented Rate
2013-02-12 09:23:50

Lawrence LeBlond for redOrbit.com - Your Universe Online Editor's note (Feb 16): This story earlier reported that thermokarst failures were occurring do to permafrost melt. However, permafrost doesn't melt, it thaws. The changes have been made to this story to reflect that. Researchers studying Arctic thermokarst failures in Alaska were alarmed to find climate-warming carbon dioxide gas may be releasing into the atmosphere at an unprecedented rate. This release is being caused by...

Understanding Travel Patterns Of Microbes Blowing In The Wind
2013-02-07 09:32:18

U.S. Department of Agriculture (USDA) With help from a wind tunnel and the latest DNA technology, U.S. Department of Agriculture (USDA) scientists are shedding light on the travel patterns of microbes in soils carried off by strong winds. The work has implications for soil health and could lead to management practices that minimize the damage to soils caused by wind erosion. Wind erosion is an emerging issue in soil conservation efforts. Agricultural Research Service (ARS) scientists...

Scientists have developed a new way to rescue the Bogong High Plains and their endangered alpine wetlands from invading European willows. The new strategy calls for an exclusive focus on eradicating willows within the threatened bogs — patches of muddy ground where the soil is always wet, says Dr Joslin Moore from the National Environmental Research Program´s (NERP) Environmental Decisions Hub and the Royal Botanic Gardens Melbourne. “After a severe bushfire burned out...

Chiton Teeth Inspire Solar Cell, Lithium-ion Improvements

[ Watch the Video: Using Snail Teeth to Improve Solar Cells and Batteries ] April Flowers for redOrbit.com - Your Universe Online A new study led by the University of California, Riverside's Bourns College of Engineering is using the teeth of a coastal California marine snail to create less costly and more efficient nanoscale materials in an effort to improve solar cells and lithium-ion batteries. Published in the recent issue of Advanced Functional Materials, assistant professor of...

Wetland
2013-04-19 18:19:23

A wetland is an area of land that is saturated with water, either permanently or seasonally, such that it takes on the traits of a distinct ecosystem. First and foremost, the factor that distinguishes the wetlands from other land forms or water bodies is the unique vegetation that has adapted to its characteristic soil conditions. The wetland consists mostly of hydric soil, which is supportive of aquatic plants. The water that is found in wetlands can be saltwater, brackish, or freshwater....
