Planetary geoscience, paleontology, and more at GSA Annual Meeting in Denver next month

Date:9/19/2007

lutionary events were a consequence. This interdisciplinary Pardee Keynote Symposium presents a comprehensive synthesis of relationships among oxygen levels, evolution, and extinctions from a variety of perspectives. Topics include: analysis of major and minor mass extinctions in light of results from the newest generation of models computing past oxygen and carbon dioxide levels; and recent evidence linking rapid global warming and associated anoxia in the past to paleontological and molecular fossil evidence. A new model for mass extinctions that differs greatly from the understanding of an impact-associated mass extinction will be discussed.

Identifying America's Most Vulnerable Oceanfront Communities: A Geological Perspective
Sunday, 28 October, 1:30-5:30 p.m., CCC 708-710-712

This Pardee Keynote Symposium focuses on 12 beaches at extreme risk of destruction, several of which have already been destroyed at least once. In a context of rising sea level and increased storm activity, top coastal experts address common geologic and historic risk factors and weigh future options for these communities. Long-term ramifications of continued coastal development and engineering during a time of global change will be discussed.

New Data, Models, and Concepts of the San Andreas Fault System
Tuesday, 30 October, 1:30-5:30 p.m., CCC 605-607

New results from the San Andreas Fault Observatory at Depth (SAFOD) and other ongoing studies will be presented in this Pardee Keynote Symposium focused on the San Andreas Fault system in central California. The first-ever core samples recovered from an active, plate-bounding fault at seism
