Israel as a Natural Gas Exporter? Posted: 05 Jan 2011 07:34 PM PST A major gas field discovered in the Mediterranean off the coast of Israel may convert the country from a major importer of natural gas to a significant exporter.

First Underwater Robot to Cross the Atlantic Posted: 05 Jan 2011 07:18 PM PST “The first underwater robotic vehicle — or "glider" — to cross an ocean will be the centerpiece of a new exhibit in the Sant Ocean Hall at the Smithsonian National Museum of Natural History.”

Arizona: Debris Flow Hazards on Alluvial Fans Posted: 05 Jan 2011 06:55 PM PST “This study evaluated methods to quantify the risk of debris-flow initiation and runout potential to impact alluvial fan flooding hazards in Maricopa County. Debris flows are unsteady, non-uniform, very poorly sorted sediment slurries that are generated when hillslope soils become saturated and fail.” Quoted from the Arizona Geological Survey’s Open File Report.

Corals Provide Evidence of Changing Oceanic Currents Posted: 05 Jan 2011 06:53 PM PST “Examination of deep sea corals reveals that there have been drastic changes to oceanic currents in the western North Atlantic since the 1970s. The influence of the cold water Labrador Current, which is in periodic interchange with the warm Gulf Stream, has been decreasing continually since the 1970s. ” Quoted from the EAWAG press release.
