▪ Abstract Ground penetrating radar (GPR) is a near-surface geophysical technique that can
provide high resolution images of the dielectric properties of the top few tens of meters of the …

Microorganisms participate in a variety of geologic processes that alter the chemical and
physical properties of their environment. Understanding the geophysical signatures of …

This study provides an evaluation of the utility and resolution of different geoelectrical
methods in mapping contaminant distribution in the subsurface, and provides a window into …

Geophysical site characterization investigations at fuel spill sites have been generally
guided by a working hypothesis which assumes that the light non-aqueous phase liquids …

The presence of free charges and numerous discontinuities separating liquid, gas, and solid
phases in partially saturated soils give rise to Maxwell‐Wagner polarization that may …

Geophysical methods can be used to obtain an image of the near surface of the earth. This
image will display the spatial variation in the geophysical properties of the subsurface. In …

A method for tomographically estimating electromagnetic (EM) wave attenuation based on
analysis of centroid frequency downshift (CFDS) of impulse radar signals is described and …

We investigated the bulk electrical conductivity and microbial population distribution in
sediments at a site contaminated with light nonaqueous-phase liquid (LNAPL). The bulk …

Near surface electromagnetic geophysical techniques are proven tools to support soil
ecosystem services and soil exploration. Such geophysical techniques provide …

Methods for remote and ground‐based sensing of soil water content often rely on
determination of bulk dielectric permittivity which may be affected by factors other than water …
