Erosion News Stories
Current Erosion News Events, Discoveries and Articles
Invisible waves shape continental slope
A class of powerful, invisible waves hidden beneath the surface of the ocean can shape the underwater edges of continents and contribute to ocean mixing and climate, researchers from The University of Texas at Austin have found. (2008-07-01)
Special topics in environmental mechanics
With rapid development of economics since the 1980s, people have been increasingly realized that the environment plays an important role in the sustainable development of society and economy. (2008-07-01)
Feeding and fueling the future: the bioenergy potential of reviving abandoned agricultural land
Across the globe, hundreds of millions of acres of once-productive agricultural land lie abandoned, according to a new report from researchers at Stanford University and the Carnegie Institution for Science. If this land was used to grow crops for conversion into biofuel, it could help ease the energy crunch without worsening the world food shortage or contributing to global warming. (2008-06-25)
Ebb and flow of the sea drives world's big extinction events
If you are curious about Earth's periodic mass extinction events such as the sudden demise of the dinosaurs 65 million years ago, you might consider crashing asteroids and sky-darkening super volcanoes as culprits. (2008-06-16)
Ecological globalization
Ecosystems are constantly exchanging materials through the movement of air in the atmosphere, the flow of water in rivers and the migration of animals across the landscape. (2008-06-02)
Reforestation using exotic plants can disturb the fertility of tropical soils
In many regions of the world, the impact of human activity on the environment intensified considerably over the past century. The high world population growth rate and the expansion of areas given over to crop production associated with climatic changes (longer periods of drought, irregular rainfall patterns) induced by global warming, have contributed to the acceleration of desertification. (2008-05-30)
Some biofuels might do more harm than good to the environment, study finds
Biofuels based on ethanol, vegetable oil and other renewable sources are increasingly popular with government and environmentalists as a way to reduce fossil fuel dependence and limit greenhouse gas emissions. (2008-05-28)
Nitrogen retained through loss
The nitrogen cycle plays a major role in seagrass fields. Dutch researcher Arie Vonk studied the nitrogen dynamics of seagrasses in Indonesia. He discovered that the interaction between seagrasses, animals and microorganisms results in an efficient nitrogen cycle in tropical seagrass fields. Consequently the nitrogen lost from seagrasses is still retained. (2008-05-23)
Culture affects how teen girls see harassment
Teenage girls of all ethnic and socioeconomic backgrounds still experience sexism and sexual harassment - but cultural factors may control whether they perceive sexism as an environmental problem or as evidence of their own shortcomings. (2008-05-15)
Woody and aquatic plants pose greatest invasive threat to China
Although China currently has fewer invasive woody plants than the United States, China's potential for invasion by nonnative trees and shrubs is high, according to an article in the May 2008 issue of BioScience. (2008-05-01)
