Science Nation - Antarctica Rocks

submitted by: nsf
Geologist John Goodge looks for clues about Antarctica's past in the two percent of the continent that is not covered in ice! The University of Minnesota, Duluth professor studies rocks that help provide evidence about how this desolate continent has formed and changed over time. He also hopes to get a better idea of what the Earth looked like long before the seven continents we have now. Goodge and his colleagues are supported by the U.S. Antarctic Program, which is managed by the National...

Super-eruptions: Volcanic Activity with a Global Impact; Stephen Self, Volcano Dynamics Group, Department of Earth Science, The Open University, Senior Volcanologist, US NRC - Every now and again, Earth suffers from tremendous explosive volcanic eruptions, much bigger than those witnessed in modern times. Although the return period for such events is long, perhaps every 10-100,000 years depending on the size, it is statistically more likely that Earth will next experience a large...

Scenario-Based Seismic Loss Estimation for San Diego County, California: Loren Wimmer, M.S. Candidate, Department of Geological Sciences, San Diego State University, Advisor Dr. Steven Day - A study was done to estimate seismic losses to San Diego County, California, and test the sensitivity of those loss estimates to the choice of ground motion model. The scenario chosen was a magnitude 7.1 earthquake on the Rose Canyon Fault Zone. A rupture surface for this scenario was defined following...

Biotic Response of Ostracodes to the Middle Eocene Climatic Optimum (MECO; 40.0 Ma) in the Southern Indian Ocean (ODP Site 748): Jared Warner, M.S. Candidate, Department of Geological Sciences, San Diego State University - The long-term cooling trend from “greenhouse” to “icehouse” conditions through the middle-to-late Eocene (49.0 – 33.7 Ma) was interrupted by the middle-Eocene Climatic Optimum (MECO; ~40.0 Ma), a transient (~500 kyr) global warming of ~4-6 C° widely recorded in...

The Recent Prehistoric Geochemical Evolution of Summit Lavas From Kilauea Volcano, Hawaii: Dale Burns, M.S. Candidate, Department of Geological Sciences, San Diego State University - Lavas from Kilauea Volcano display rapid geochemical and isotopic variations (e.g., 206Pb/204Pb or Nb/Y ratios) on a time scale of decades to centuries. The wall of Kilauea Caldera at Uwekahuna Bluff exposes a sequence of recent prehistoric, caldera-filling lavas (erupted mostly between AD 900-1400). Here we...
