Large concentrations of magnetite in sedimentary deposits and soils with igneous parent material have been reported to affect geophysical sensor performance. We have undertaken the first systematic experimental effort to understand the effects of mag

Magnetic behavior of soils can seriously hamper the performance of geophysical sensors. Currently, we have little understanding of the types of minerals responsible for the magnetic behavior, as well as their distribution in space and evolution throu

Internal erosion is one of the main causes of earthen structure failure. The early signature of internal erosion is important in identifying a possible failure point. In this study, we test the feasibility of using electrical resistivity tomography t

We report complex permittivity, conductivity, magnetic susceptibility, and attenuation for soils collected from a typical site in a current theater of operations. Our experimental setup consists of three network analyzers along with custombuilt sampl

Buried infrastructure at Military Construction (MILCON) project sites can cause large project cost overruns if not located and removed prior to the start of the project. This project demonstrated how geophysical survey tools can be utilized to locate
