Fortieth Anniversary of Sloss's Cratonic Sequences: Sequence Stratigraphy of the Sauk Sequence
GSA Sedimentary Geology Division
Kevin R. Evans, Southwest Missouri State University, Springfield, MO; James F. Miller, Southwest Missouri State University, Springfield, MO
- Sloss's classic publication on North American stratigraphy introduced the concept of Sequences. We encourage papers on all aspects of sequence stratigraphy within the Sauk Sequence. This session follows a field trip to spectacular localities in western Utah. ORAL and POSTER
- Stratigraphy; Sediments, Carbonates; Paleontology/Paleobotany

Clinoforms: Past, Present, and Modeled
GSA Sedimentary Geology Division; Society for Sedimentary Geology
Charles A. Nittrouer, University of Washington, Seattle, WA; Lincoln F. Pratson, Duke University, Durham, NC; David Mohrig, Massachusetts Institute of Technology, Cambridge, MA
- Clinoforms are a fundamental unit of stratigraphy that is observed in a range of sedimentary environments over scales of centimeters to tens of kilometers. This session will examine observational (modern and ancient), experimental, and modeling studies of their formation. ORAL and POSTER
- Stratigraphy; Sediments, Clastic; Marine/Coastal Science

Advances in Stratigraphic Analyses Using Ground Penetrating Radar
GSA Geophysics Division; GSA Engineering Geology Division; GSA Sedimentary Geology Division
Gregory S. Baker, University at Buffalo (SUNY), Buffalo, NY; Harry M. Jol, University of Wisconsin, Eau Claire, WI
- The session will cover a broad range of ground penetrating radar (GPR) studies related to stratigraphic analyses. Topics include reservoir and environmental site characterization, hydrogeophysics, geological hazard investigation, and stratigraphic-facies analyses of geomorphic environments (including eolian, fluvial, glacial, and coastal). ORAL and POSTER

The Geologic Record of Biosphere Dynamics-The Key to Understanding the Biotic Effects of Future Environmental Change
GSA Geobiology and Geomicrobiology Division
Karl W. Flessa, University of Arizona, Tucson, AZ; David A. Feary, National Research Council, Washington, D.C.
- This session will focus on a recent National Research Council report that proposes strategies for integrating earth and biological sciences as a means of understanding biotic response to environmental change, and recommends programmatic, infrastructural, and management changes to best advance this emerging interdisciplinary science area. ORAL
- Geomicrobiology

Geology and Paleoecology of the Beringian Subcontinent: To Honor the Career of David M. Hopkins
Alaska Quaternary Center (AQC)
Sarah J. Fowell, University of Alaska, Fairbanks, AK; Patricia Heiser, University of Alaska, Anchorage, AK
- The concept of Beringia as a subcontinent with a unique flora and fauna can be largely attributed to David M. Hopkins. This session will highlight current research by Dave's students, coworkers, and colleagues. Presentations should focus on advances in Beringian paleoecology and future research directions. ORAL and POSTER
- Quaternary Geology/Geomorphology; Paleoclimatology/Paleoceanography; Archaeological Geology

Testing Rodinia Using New Maps Compiled for Each Craton through IGCP 440
GSA Structural Geology and Tectonics Division, International Geologic Correlation Project; Tectonics Special Research Center
Karl E. Karlstrom, University of New Mexico, Albuquerque, NM; Svetlana V. Bogdanova, University of Lund, Lund, Sweden
- The pre-Pangean supercontinent of Rodinia has been the subject of debate since it was proposed over a decade ago. This session will present results from an international correlation project (IGCP 440) designed to compile new data from each craton to test some of the numerous models for the shape, evolution, and even the existence of Rodinia. ORAL
- Tectonics; Precambrian Geology

New Perspectives on Neoproterozoic-Early Paleozoic Development of Western Laurentia: In Honor of John Cooper
GSA Sedimentary Geology Division
Mike Pope, Washington State University, Pullman, WA; Chris Fedo, George Washington University, Washington, D.C.
- This session will examine new perspectives (e.g., detrital zircon geochronology, LA-MC-ICP-MS, detailed sequence stratigraphy, isotope chemostratigraphy, geobiology, etc.) that are being used to determine the Neoproterozoic-Early Paleozoic development of western Laurentia. ORAL and POSTER
- Stratigraphy; Sediments, Carbonates; Sediments, Clastic
- T128
Barremian to Turonian Carbonate Platform Facies in Northeastern Mexico, their Paleogeographic, Paleoceanic, and Paleoclimatic Implications: Comparison with Coeval Facies Elsewhere in the Tethys (Posters)
GSA Sedimentary Geology Division; Society for Sedimentary Geology
Florentin J. Maurrasse, Florida International University, Miami, FL
- Comparison of Lower to Upper Cretaceous facies of northeastern Mexico with coeval deposits around the Tethys for a better understanding of spatial and temporal changes in relation to the paleogeography, paleoceanography, and paleoclimate of that time interval. POSTER
- Stratigraphy; Paleoclimatology/Paleoceanography; Sediments, Carbonates
- T129
The Jurassic System of North America: Stratigraphy, Tectonics, and Depositional History (Posters)
GSA Structural Geology and Tectonics Division; GSA Sedimentary Geology Division; Society for Sedimentary Geology
