New Feature at SAGEEP 2009: Session Keynotes

A new feature for SAGEEP 2009 is five presentations that have been designated as Session Keynotes. A preliminary list of Special Sessions, Sessions, Chair(s) and Oral Presentation titles follows.

Odysseus Unbound: Geophysics in the Search for Homer’s Ithaca
Presented by Greg Hodges, Chief Geophysicist, Fugro Airborne Surveys
The Odysseus Unbound project includes analysis of the Paliki Peninsula for supporting evidence that it was once the island of Ithaca, home of Odysseus. Geophysical surveys including airborne EM, magnetometry and LIDAR; marine seismic surveys; and ground resistivity, magnetometry, gravity and seismic refraction are being used to read the geological history of this island over the last 3200 years.

The Self-Potential Method: Did the Ugly Duckling of Environmental Geophysics Become a Beautiful Swan?
Presented by Andre Revil, Professor, Colorado School of Mines
While discovered in the first part of the 19th Century, the self-potential method has been considered for a long time as a scientific curiosity and was nicknamed by some researchers as the ugly duckling of environmental geophysics. Over the past 15 years, the self-potential method has been developed to the point where it can be considered as a powerful method in hydrogeophysics.

The “Nuclear Renaissance” and its Implications for Geophysics
Presented by Tom Dobecki, Chief Geophysicist, Shaw Environmental and Infrastructure
With promises from Presidential candidates and an almost-acceptance from many environmental groups, nuclear power plants are a topic of conversation and a work opportunity for geophysicists. It has been nearly 40 years (a geophysical generation) since the last US nuclear power plant went through licensing – so are we ready to support this task and cross all the hurdles between the proposal and turning on the switch?

Robust, Broadband Finite Difference Time Domain Modeling of EM Propagation in the Subsurface
Presented by Jeffrey Daniels, Professor and Assoc. Dean for Research and Graduate Studies, College of Mathematical and Physical Sciences, The Ohio State University
Three dimensional finite difference time domain modeling (FDTD) has been used for many years. Early versions were fraught with problems, including an inability to model a broad range of frequencies, difficulty modeling large physical property contrasts, and no ability to vary the grid size within the model. A new FDTD modeling capability allows accurate forward modeling over a wide frequency range (1 MHz – 2 GHz), a wide range of EM properties, and includes a graphical interface engine to simplify and expedite the input of 3D models.

Soil Magnetism Research: State of the Art and Future Directions
Presented by Remke Van Dam, Asst. Professor, Michigan State University
A recent international workshop was held to define the current state of knowledge about soil magnetic properties and recommend directions for future research. Magnetic soil properties are traditionally investigated in studies of soil development, climate, and pollution as well as a rapid tool for archaeological site assessments. More recently, the potentially deleterious impacts of soil magnetism on detection of targets such as UXO and landmines have been recognized. However, little information is available globally that allows for effective mitigation strategies for UXO and landmine detector technologies.
