Scientists From Across the Globe Warn of Drastic Water Shortages

submitted by: ucsandiego
In the Sierra Neveda, snowpack will shrink by 30 to 90 percent by the end of the century. On the other side of the planet, in the Himalayas, about 70 percent of glaciers are set to disappear. These changes are both caused by climate change and will lead to dramatic water shortages for hundreds of millions of people across the globe, scientists said during a press conference Wednesday at UC San Diego. http://ucsdnews.ucsd.edu/thisweek/2009/05/11_icemelt.asp

Chemical and Physical Characteristics of Pulverized Tejon Lookout Granite Adjacent to the San Andreas and Garlock Faults: Implications for Earthquake Physics: Matthew Sisk, M.S. Candidate, Department of Geological Sciences, San Diego State University - We present new detailed analysis of pulverized Tejon Lookout granite from sections adjacent to the San Andreas and Garlock faults in southern California. The granite is pulverized in all exposures within about 100 m from both faults....

2008 Tawani Antarcitc Expedition Video

submitted by: Edeker
In November 2008, an international team of distinguished scientists, educators and explorers embarked on a six week expedition to Antarctica. Their primary mission was to study the icy ecosystems of the Schirmacher Oasis and the perennially ice-covered Lake Untersee. In this exceptionally hostile environment, the team hoped to find a new species of "extremophile" - a hardy life form that exists and flourishes in conditions inhospitable to most known organisms. These discoveries could...

TIR spectroscopy of shocked Deccan basalt: Implications for Mars and Martian meteorites: Shawn Wright, Institute of Meteoritics, Department of Earth and Planetary Sciences, University of New Mexico - Hundreds of thousands of impact craters dominate the surfaces of the Moon, Mercury, and Mars. There exists much geomorphic and spectral evidence for basalt on those surfaces, so basaltic target rocks are most likely common. However, little work has been done on the thermal infrared (TIR)...

Imaging Fault Damage Zones with Seismic and Geodetic Data - Elizabeth Cochran, Department of Earth Sciences, University of California, Riverside: During earthquakes slip is often localized on preexisting faults, but it is not well understood how the structure of crustal faults may contribute to slip localization and energetics. Growing evidence suggests that the crust along active faults suffers anomalous strain and damage during large quakes. Data collected along several faults including...

Not-So-Simple Cinder Cone Plumbing Systems: Examples From the Sierra Nevada - Brandon Browne, Department of Geological Sciences, California State University Fullerton: Cinder cones situated in continental monogenetic volcanic fields are generally thought to erupt single magma batches over short periods of time. However, field mapping efforts combined with petrologic, geochemical, and thermobarometric analysis of erupted products from two unrelated volcanic fields in California (Red Cones, 5...
