'Hidden-hero' microbes in soil, water may help naturally clean toxic sites

...aches into groundwater that extends in radioactive plumes for miles from the contaminated site. But soon, Florida State University Associate Professor Joel Kostka and his FSU oceanography department team will help clean up the mess. During the course of a forthcoming five-year study funded by the U.S. ...

Extraordinary life found around deep-sea gas seeps

...ap seafloor topography and substrate and to detect plumes of methane-enriched water. The scientists then lowered a towed video and still camera system over each site to identify seep organisms and the extent of the seafloor they covered. With the live video feed, the scientists observed 30?0 cm long tube...

Breath of the dragon: ERS-2 and Envisat reveal impact of economic growth on China's air quality

...rces over China that overlap with nitrogen dioxide plumes are linked to power plants. Further to the west there is also sulphur dioxide produced from smouldering underground coal seam fires. Burrows is the scientist who - supported by an international team - proposed both GOME and SCIAMACHY to national s...

Sensor web simulation investigates technique to improve prediction of pollution across the globe

...as lightning induced wildfires that can emit large plumes of particulates into the troposphere. Fossil fuel burning in industrial areas and vehicular traffic in metropolitan areas are also major pollutant sources. Complex chemical interactions and atmospheric processes can transport these pollutants across ...
