Second International Workshop on Induced Polarization in Near-Surface Geophysics

October 31 - November 2, 2011

Workshop Description

This workshop will be the continuation of a previous workshop entitled "International Workshop on Induced Polarization in Near-Surface Geophysics", held in Bonn, Germany September 30-October 1, 2009. The aim of that workshop was to present recent developments and applications of the method for near-surface hydrogeological and environmental investigations. The 2011 workshop will focus specifically on improving our understanding of the mechanisms generating IP signals in the Earth.

Induced polarization (IP) or complex resistivity (conductivity or permittivity) is a non-intrusive geophysical method used to image the subsurface. Although historically developed to detect ore bodies, the IP method has more recently emerged as an exciting technology in the emerging field of hydrogeophysics and biogeophysics. In particular, literature over the last decade has conclusively demonstrated the unique potential of the IP method as a geophysical imaging tool for characterization of hydraulic properties and monitoring of biogeochemical transformations in the subsurface.

These recent developments have been in part driven by considerable improvements in instrumentation, macroscopic modeling and tomography techniques and the understanding of the microscopic origin of IP at the pore scale levels. However, there is still a gap in our fundamental understanding of IP mechanisms and a unified theory is still missing. Consequently, the full potential of the IP method as a non-invasive subsurface imaging tool has not been exploited. One fundamental problem is that various polarization mechanisms exist and may overlap in the frequency range of laboratory and field measurements.
