Frozen arctic soil contains nearly twice the greenhouse-gas-producing organic material as was previously estimated, according to recently published research by University of Alaska Fairbanks scientists. School of Natural Resources & Agricultural Sciences professor Chien-Lu Ping published his latest findings on the Nature Geoscience and Scientific American Web sites. Wielding jackhammers, Ping and a team of scientists dug down more than one meter into the permafrost to take soil samples...

TUCSON, Ariz. -- A fork-like conductivity probe has sensed humidity rising and falling beside NASA's Phoenix Mars Lander, but when stuck into the ground, its measurements so far indicate soil that is thoroughly and perplexingly dry. "If you have water vapor in the air, every surface exposed to that air will have water molecules adhere to it that are somewhat mobile, even at temperatures well below freezing," said Aaron Zent of NASA Ames Research Center, Moffett Field, Calif., lead scientist...

Greenhouse gas emissions from previously frozen organic carbon in soil are seen as larger than previously believed The thawing of permafrost in northern latitudes, which greatly increases microbial decomposition of carbon compounds in soil, will dominate other effects of warming in the region and could become a major force promoting the release of carbon dioxide and thus further warming, according to a new assessment in the September 2008 issue of BioScience. The study, by Edward A. G. Schuur...

Scientists have found that the ground is drying out in a 13,700-year-old peat bog, just another sign, they say, of the Earth's warming climate. Ecologist Ed Berg says the peat bog is turning into forest. "There has been a big change," Berg said. Core samples taken from the bog show moss nearly 22 feet under the ground, with no sign of trees or shrubs growing here for centuries, Berg said. The bog could be covered by black spruce trees during the next 50 years, he said. Alaska is one state,...

By CHARLIE PATTON HILLIARD - As he watched the two-minute promotional DVD in his living room, Frank Watts got a little emotional. "This brings goose bumps to me," Watts said. Soil has that effect on Watts, a 64-year-old pedologist who has spent his life digging around in what he refuses to call dirt. "I don't like the word 'dirt,' " he said. It's soil. Soil, as the two-minute promotional clip documents, is the subject of a new exhibition at the Smithsonian National Museum of Natural...

TOOLIK LAKE, Alaska _ Ground here that for tens of thousands of years was frozen solid is terra firma no more. Across the tundra and coast of the Arctic Ocean, land is caving in. Soils loosed by freshly thawed earth set off a new era of rot, and of bloom _ dumping a bonanza of nutrients into a top-of-the-world environment that swirls from months of midnight sun to deep-freeze dark. Will nature channel the nourishment of this soil into a great flowering of plant life that soaks up...

By Susan Kuczka, Chicago Tribune Jun. 18--Fox Waterway Agency workers temporarily staked three massive floating bogs to the Grass Lake shoreline Tuesday, preventing a potentially dangerous backup of floodwater from the Fox River. The bogs had broken off from the Chain O' Lakes State Park and Conservation Area. "The thing is huge," said Ingrid Ruttendjie, the agency's executive director, after taking a boat tour of the land mass that had plugged the channel connecting Glass Lake and Lake...

The rate of climate warming over northern Alaska, Canada, and Russia could more than triple during periods of rapid sea ice loss, according to a new study led by the National Center for Atmospheric Research (NCAR). The findings raise concerns about the thawing of permafrost, or permanently frozen soil, and the potential consequences for sensitive ecosystems, human infrastructure, and the release of additional greenhouse gases."Our study suggests that, if sea-ice continues to contract rapidly...

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....
