AUSTIN, Texas—Conducting a rapid response research mission after Hurricane Ike, scientists at The University of Texas at Austin surveyed the inlet between Galveston Bay and the Gulf of Mexico, discovering the hurricane significantly reshaped the seafloor and likely carried an enormous amount of sand and sediment out into the Gulf.
A resounding vote of international petroleum geologists from around the globe concluded that the mud volcano was triggered by drilling of a nearby gas exploration well.
This may have implications for compensation of the local population affected.
Lusi started to erupt in East Java, Indonesia, on May 29th 2006, and is still spewing huge volumes of boiling mud over the surrounding area. It has displaced around 30,000 people from their homes and swamped 12 villages.

Boulder, CO, USA - The latest issue of GSA BULLETIN spans the globe, examining ancient soils in Big Bend National Park, Texas; loess soils in Nebraska, including the greatest known thickness of the Peoria Loess in the world; folding, faulting, and metamorphism as seen in detailed geologic mapping across Pakistan; tectonic fractures in Southeast Viti Levu, Fiji; subsidence in Mexico City; groundwater arsenic in Araihazar, Bangladesh; the formation of the Andes; and earthquakes in the Seattle fault zone.

After eight years of near-zero growth in atmospheric methane concentrations, levels have again started to rise.
"This is not good news for future global warming," says CSIRO's Dr Paul Fraser, who co-authored a paper to be published in Geophysical Research Letters, a journal of the American Geophysical Union.
A quarter-million people were killed when a tsunami inundated Indian Ocean coastlines the day after Christmas in 2004. Now scientists have found evidence that the event was not a first-time occurrence.
A giant Atlantic bluefin tuna weighing more than half a ton had the honor of being fitted with the 1000th electronic tracking tag placed on this threatened species when it was caught and released on Monday (October 20) in the Gulf of St. Lawrence off Port Hood, Nova Scotia.
(Washington, DC – October 29, 2008) The U.S. Environmental Protection Agency (EPA) is collaborating with the National Geographic Society and the World Resources Institute to develop tools that will help to fully account for the value of ecosystem services.
Ecosystem services are the goods and services people obtain from natural systems. These benefits include clean air and water, erosion and flood control, soil enrichment, food, and fiber.

EPFL researchers have developed a numerical model that can re-create the state of Switzerland's Rhône Glacier as it was in 1874 and predict its evolution until the year 2100. This is the longest period of time ever modeled in the life of a glacier, involving complex data analysis and mathematical techniques.The work will serve as a benchmark study for those interested in the state of glaciers and their relation to climate change.
The thickness of sea ice in large parts of the Arctic declined by as much as 19% last winter compared to the previous five winters, according to data from ESA's Envisat satellite.
Athens, Ga. – Current models of global climate change predict warmer temperatures will increase the rate that bacteria and other microbes decompose soil organic matter, a scenario that pumps even more heat-trapping carbon into the atmosphere. But a new study led by a University of Georgia researcher shows that while the rate of decomposition increases for a brief period in response to warmer temperatures, elevated levels of decomposition don't persist.
