RESEARCH:

Current research in progress:

  • "Microbial Influences on Geophysical Signatures: A Proxy for the Understanding and the Monitoring of Natural Attenuation", funded by U.S. Department of the Interior, Geological Survey, Regional Water Resources Research Program (Missouri): In this collaborative project with Dr. Estella Atekwana (University of Missouri - Rolla) we are studying the role of electrical geophysics as potential non-invasive indicators of natural attenuation of organic sediments. Laboratory column experiments have been designed in which geochemical indicators of bioremediation will be compared with the frequency dependent electrical response.

  • "Investigating the complex resistivity (0.01-1000 Hz) response to saturation state for unconsolidated sediments",  funded by the National Science Foundation, Earth Sciences ProgramIn this laboratory project we are determining the low-frequency (0.1-1000 Hz) electrical response of a range of unconsolidated sediments during saturation and drainage. In particular, we are studying changes in the polarization at the grain-fluid interface as saturation changes. Link to NSF Award Abstract

  • "Improving interpretation of lithological parameters from Spectral Induced Polarization (SIP) measurements", funded by the American Chemical Society - Petroleum Research Fund: In this laboratory project we intend to make measurements of the low-frequency (0.1-1000 Hz) clay-sand mixtures with varying clay mineralogy. We hope to improve understand of the induced polarization response of unconsolidated materials.  

  • "Collaborative research: Evaluation of mass transport in a large Maine peatland", funded by the  National Science Foundation, Earth Sciences Program:: In this collaborative project with Dr. Andrew Reeve (Dept. of Geology at U.Maine) we adopting a joint hydrogeological/geophysical approach to the study of the controls on nutrient transport in a large peatland. Included in this work are fundamental laboratory measurements to evaluate the electrical properties of organic sediments. The field geophysics includes (a) stratigraphic mapping using resistivity, induced polarization and ground penetrating radar (b) long term tracer monitoring using electrical imaging. Link to NSF Award Abstract

 

  • "Electrical geophysics to assist evaluation of reactive barrier integrity and performance", funded by the U.S. Department of Energy: In this project we are evaluating the utility of high resolution 2D/3D cross-borehole electrical imaging (resistivity and induced polarization) for determining the integrity of permeable reactive barriers (PRBs). Our measurements at the Kansas City DOE plant indicate that electrical imaging is a highly effective approach to PRB characterization.

COMMUNITY

Students enrolled in  Geophysics classes engage in field experiences designed to help the local community. During the Winter 2000 semester students conducted a 2-day field survey at the historic Vaile Mansion, in Independence, Missouri. The Vaile Historic Preservation Society is engaged in reconstructing the past in the grounds of this 120 year old house. UMKC students used modern geophysical equipment in an effort to locate foundations of old buildings, old pipes and a lost wine cellar.
