Special Technical Sessions

All sessions will take place at the Minneapolis Convention Center, 1301 Second Avenue South, Minneapolis, Minnesota 55403 USA.

The following special sessions extend and enhance opportunities for diverse learning and presentation modes within the technical program. Each four-hour session will be structured by the individual organizers to best fit their purpose, in order to provide an interesting and unique session for the meeting attendees. For more information on these sessions, please contact the organizers.

GSA Geophysics Division 40th Anniversary Special Session
(GSA Geophysics Division)
Walter Mooney,USGS; Randy Keller University of Oklahoma; Kevin Mickus, Missouri State University; Audrey Huerta, Central Washington University
This special session is to celebrate the 40th anniversary of the GSA Geophysics Division. Geophysical studies of lithospheric structure, composition and evolution — from the near surface to the lithospheric-asthenospheric boundary - have made giant leaps during the past decades. We highlight the major scientific discoveries concerning the lithosphere, from top to bottom, with invited keynote presentations of past George P. Woollard (GSA Geophysics Division) award winners. The last talk will be given by the 2011 George P. Woollard award winner.

The Past Yucca Mountain Project—Advancing Science and Technology for the Future: Was It Worth the Cost?
Richard R. Parize, The Pennsylvania State University; Claudia M. Newbury, US DOE (retired); Ardyth M. Simmons, Los Alamos National Laboratory
Regulatory requirements for a nuclear waste repository at Yucca Mountain, Nevada, anticipated that characterization of the natural system and calculations of future performance would use established methodologies and technologies, but these were not always sufficient for the time scales and level of detail required. During the life of the program (1988–2010), approximately $1.1B was spent on scientific and technical investigations across a wide range of disciplines. This symposium reviews the innovative work conducted by the program investigators, transfer of those methodologies and technologies to the wider scientific community, and asks the question — was it worth the price?

Crossing the Digital Divide: Availability of Geoscience Knowledge for Resolving Environmental and Societal Challenges
(GSA Environmental and Engineering Geology Division; GSA Hydrogeology Division; GSA Geoinformatics Division; GSA Geology and Society Division; American Association of State Geologists; U.S. Geological Survey; British Geological Survey)
A. Keith Turner, Colorado School of Mines; D.A. Keefer, Illinois State Geological Survey; Holger Kessler, British Geological Survey
This special session addresses the entire digital geoscience data collection, management, and dissemination process, including: making and maintaining digital data resources, digital tools for 3D/4D geologic modeling, associated process modeling, visualization, and options for collaborative web-enabled outreach. Experiences with process modeling for hydrogeologic investigations have led the USGS, the British Geological Survey, and the Illinois Geological Survey, to adopt an integrated holistic Earth modeling approach, supported by digital data management, visualization, and dissemination tools, and to focus on development of linked-process models across a range of earth and social science processes.

Planetary Geology Division 30th Anniversary—Then And Now: The Past 30 Years Of Solar System Exploration
(GSA Planetary Geology Division)
Simon A. Kattenhorn, University of Idaho; David Williams, Arizona State University;
This session will provide a retrospective on the major advances in understanding the geologic histories of planets and moons over the past 30 years, in celebration of the 30th anniversary of the Planetary Geology Division. We describe the history of solar system exploration in this time frame with emphasis on characterizing planetary surfaces and unraveling the geologic processes and histories that have resulted in the astounding geologic diversity of our solar system.

Water and Sediment Dynamics in Agricultural Landscapes: Towards Prediction of Watershed Sediment Yield
(GSA Quaternary Geology and Geomorphology Division; GSA Environmental and Engineering Geology Division; GSA Hydrogeology Division; GSA Geology and Society Division; GSA Geophysics Division; GSA Geoinformatics Division; Soil Science Society of America)
Patrick Belmont, Utah State University; Karen B. Gran, University of Minnesota–Duluth; Carrie E. Jennings, University of Minnesota
This session brings together a diverse group of geographers, geomorphologists, hydrologists, soil scientists, and agricultural scientists to evaluate approaches for predicting water and sediment yield in agricultural landscapes.
