*Krafla volcano gives geologists unique, unexpected opportunity to study magma*
Geologists drilling an exploratory geothermal well in 2009 in the Krafla volcano in Iceland met with a big surprise: underground lava, also called magma, flowed into the well at 2.1 kilometers (6,900 feet) depth.
It forced the scientists to stop drilling. (more…)
A Million-Dollar Question
Sleeping Beauty’s kingdom was overgrown by vines when she fell into a deep sleep. Researchers at the Smithsonian in Panama and the University of Wisconsin at Milwaukee received more than a million dollars from the U.S. National Science Foundation to discover why real vines are overtaking the American tropics. Data from eight sites show that vines are overgrowing trees in all cases.
“We are witnessing a fundamental structural change in the physical make-up of forests that will have a profound impact on the animals, human communities and businesses that depend on them for their livelihoods,” said Stefan Schnitzer, research associate at the Smithsonian Tropical Research Institute in Panama and associate professor at the University of Wisconsin at Milwaukee.

WASHINGTON —The extreme rain events that have caused flooding across northern Australia may become an increasingly familiar occurrence, new research suggests. The study uses the growth patterns in near-shore corals to determine which summers brought more rain than others, creating a centuries-long rainfall record for northern Australia. (more…)
GAINESVILLE, Fla. — The number of reported shark attacks last year increased worldwide but declined in Florida, according to the University of Florida’s International Shark Attack File annual report released today.
Ichthyologist George Burgess, director of the file housed at the Florida Museum of Natural History on the UF campus, said Florida typically has the highest number of attacks worldwide, but 2010 marked the state’s fourth straight year of decline. Florida led the U.S. with 13 reported attacks, but the total was significantly lower than the yearly average of 23 over the past decade. (more…)
GAINESVILLE, Fla. — Twenty years after biologists attempted to determine the ecological damages to marine life from the Exxon Valdez oil spill, scientists dealing with the BP disaster find themselves with the same problem: the lack of critical data to determine the ecological consequences of human-induced environmental disasters, a University of Florida researcher said.

WASHINGTON — Five days before intense monsoonal deluges unleashed vast floods across Pakistan last July, computer models at a European weather-forecasting center were giving clear indications that the downpours were imminent. Now, a new scientific study that retrospectively examines the raw data from these computer models, has confirmed that, if the information had been processed, forecasters could have predicted extremely accurate rainfall totals 8-10 days beforehand.

*Research project completes drilling for the year, reaching two miles below West Antarctic Ice Sheet*
On Friday, Jan. 28 in Antarctica, a research team investigating the last 100,000 years of Earth’s climate history reached an important milestone completing the main ice core to a depth of 3,331 meters (10,928 feet) at West Antarctic Ice Sheet Divide (WAIS). The project will be completed over the next two years with some additional coring and borehole logging to obtain additional information and samples of the ice for the study of the climate record contained in the core.
As part of the project, begun six years ago, the team, funded by the National Science Foundation (NSF), has been drilling deep into the ice at the WAIS Divide site and recovering and analyzing ice cores for clues about how changes in the concentration of greenhouse gases in the atmosphere have influenced the Earth’s climate over time.

Being in a warm room can make the idea of global warming seem more likely, according to researchers from the University of Chicago Booth School of Business and the Haas School of Business at University of California, Berkeley. (more…)
