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...

The Cretaceous-Paleogene ("KT") Boundary In Belize and Alabama - David T. King, Jr., Department of Geology and Geography, Auburn University, Alabama: Belize - At Albion Island in northern Belize, Cretaceous-Paleogene (KT) boundary deposits, also known as the Albion formation, rest upon karsted and fractured Maastrichtian dolostones. These deposits consist of a basal impactoclastic clay layer (~ 1 to 2-m thick) and an upper carbonate-rich, coarse impactoclastic breccia layer (up to 15-m...

Calit2 Bluff Erosion Project

The cliffs along the San Diego coastline are more than just fodder for picture postcards — a number of residential homes sit perched atop them, and in certain areas, the railroad tracks that serve Amtrak and County Coaster come within several feet of the cliff edge.
