- Airborne Geophysical for Detection of Unexploded Ordnance
- Working in conjuction with researchers Oak Ridge National Laboratory, we
are working to improve the utility of airborne geophysical methods for the
detection of unexploded ordnance (UXO). A demonstration at Edwards Air Force
Base showed that helicopter-mounted magnetometers flown at and elevation of
3-5m can detect many of the typical targets of UXO surveys. My current research
focuses on correction of the data for variations in helicopter flight height.
Flying this close to the ground, even small altitude fluctuations can drammatically
alter the recorded anomaly amplitude.
- Geophysical Mapping of Shallow Karst
- Researchers at Temple University in collaboration with
engineers at Lafayette College have used a 90-acre
athletic area (Metzger Field) for several years as a
research site to study the utility of multielectrode
resistivity for mapping pinnacled bedrock and solution
features associated with karst terrain. The results of
multielectrode resistivity soundings at this site compare
favorably with drilling data. Currently, we are studying
the relative merits of 2D and 3D resisitivity imaging for
shallow karst targets.
- Spontaneous Potential Mapping of Redox Conditions
- At a test site near Oyster, VA, a negative spontaneous
anomaly correlates with a plume of groundwater emanated
from a trenches containing tomato canning wastes.
Biodegradation of the tomato waste has depleted the
dissolved oxygen in this plume and created a reducing
environment. Our research involves testing whether or not
spontaneous potential (SP) can be used to map soil and
groundwater oxidation-reduction (redox) conditions.
