- P1 Global Climate Changes: Abrupt Late Pleistocene Climatic Reversals and Modern Global Warming
GSA Quaternary Geology and Geomorphology Division
Don J. Easterbrook, Western Washington University, Bellingham, WA; Ed Evenson, Lehigh University, Bethlehem, PA; John Gosse, Dalhousie University, Halifax, NS, Canada
- This session will explore global, late Pleistocene, rapid climatic changes, focusing on the Younger Dryas and Intra-Allerod Cold Period, and aspects of global warming during the past century and earlier natural climatic changes.
- Tuesday, November 4, 8 a.m.-12 noon.
- P2 His View of Life: Reflections on the Scientific Legacy of Stephen J. Gould
Warren D. Allmon, Paleontological Research Institution, Ithaca, NY; Patricia Kelley, University of North Carolina, Wilmington, NC; Robert M. Ross, Paleontological Research Institution, Ithaca, NY
- This session will explore the legacy of Stephen Jay Gould. Speakers will reflect upon and attempt to clarify Gould's views, some of which were widely misunderstood, and explicate interrelationships among his views in disparate subjects.
- Sunday, November 2, 8 a.m.-12 noon.
- P3 Modeling Metamorphism: Petrology, Geochemistry, and Tectonics
Mineralogical Society of America, Geochemical Society; GSA Structural Geology and Tectonics Division
Michael Brown, University of Maryland, College Park, MD; Barbara L. Dutrow, Louisiana State University, Baton Rouge, LA
- Metamorphism involves the study of global-scale cycles, for example, from diagenesis to exhumation of metamorphic rocks, and from ocean floor sedimentation to formation of mountain belts and global climate change. This session addresses a broad theme that is fundamental for mineralogy, petrology, geochemistry, tectonics and earth system science.
- Monday, November 3, 1:30-5:30 p.m.
- P4 Neoproterozoic Geobiology: Fossils, Clocks, Isotopes, and Rocks
GSA Geobiology and Geomicrobiology Division; NASA Astrobiology Institute (NAI); GSA Sedimentary Geology Division; Paleontological Society; Geochemical Society; Precambrian (at large)
Shuhai Xiao, Tulane University, New Orleans, LA; Alan J. Kaufman, University of Maryland, College Park, MD
- Sedimentologists, paleontologists, geochemists, and earth system modelers are brought together to present new data and models (stimulated by the "snowball Earth" hypothesis) on the Neoproterozoic Earth, in order to better understand the relationship between tectonic, climatic, and biological change at the end of the Proterozoic Eon.
- Wednesday, November 5, 8 a.m.-12 noon.
- P5 Preservation of Random Mega-scale Events on Mars and Earth: Influence on Geologic History
GSA Planetary Geology Division
Mary G. Chapman and Lazlo Keszthelyi, U.S. Geological Survey, Flagstaff, AZ
- This session presents the state of our understanding of large-scale, rapid-acting geologic processes, such as bolide impact, superplume eruption, catastrophic flood, and edifice collapse that are obvious on Mars yet scarcely recognized on Earth.
- Tuesday, November 4, 1:30-5:30 p.m.
- P6 The Paleoenvironmental and Paleoclimatic Framework of Human Evolution
GSA Archaeological Geology Division, GSA Quaternary Geology and Geomorphology Division; GSA Sedimentary Geology Division; Society for Sedimentary Geology (SEPM)
Gail M. Ashley, Rutgers University, Piscataway, NJ; Craig S. Feibel, Rutgers State University, New Brunswick, NJ
- Recent discoveries and established facts regarding the paleoenvironment and paleoclimatic context of human evolution will be examined with the goal of shedding some light on the puzzle of human origins.
- Monday, November 3, 8 a.m.-12 noon.
- P7 The Science of Lewis and Clark: Historical Observations and Modern Interpretations
GSA Engineering Geology Division; U.S. Geological Survey; U.S. Department of the Interior; GSA History of Geology Division; History of Earth Science Society
Paul M. Santi, Colorado School of Mines, Golden, CO
- The year 2003 is the 200th anniversary of the initiation of the Lewis and Clark Expedition. This session will gather scientists, historians, and science policy makers to explore the scientific impacts of the expedition as well as the changes in scientific interpretations and government support of science since the expedition.
- Wednesday, November 5, 1:30-5:30 p.m.
