Abstract:
During the last century, electrical geophysics has been transformed from a simple resistivity method to a modern technology that uses complex data-acquisition systems and high-performance computers for enhanced data modeling and interpretation. Not only the methods and equipment have changed but also our ideas about the geoelectrical models used for interpretation have been modified tremendously. This paper describes the evolution of the conceptual and technical foundations of EM methods. It outlines a framework for further development, which should focus on multitransmitter and multireceiver

Abstract:
Electromagnetic (EM) methods are among the original techniques for subsurface characterization in exploration geophysics because of their particular sensitivity to the earth electrical conductivity, a physical property of rocks distinct yet complementary to density, magnetization, and strength. However, this unique ability also makes them sensitive to metallic artifacts — infrastructure such as pipes, cables, and other forms of cultural clutter — the EM footprint of which often far exceeds their diminutive stature when compared to that of bulk rock itself.

Abstract:
Any geophysical measurement is a filter through which the distribution of a certain physical parameter in the subsurface is seen, and the sensitivity function is a characteristic of the method that reveals the nature of this filter. Insight into the structural pattern of the sensitivity function pertaining to a certain transmitter-receiver configuration provides the geophysicist with an image that allows an immediate qualitative understanding of the characteristics of the method. The assets and shortcomings of different measuring configurations can be discussed and understood, and the sensitiv

Floridablanca is an 18th century archaeological site located in southern Argentina.

Abstract:
The size and low resistivity of the clay cap associated with a geothermal system create a target well suited for electromagnetic (EM) methods and also make electrical detection of the underlying geothermal reservoir a challenge. Using 3-D numerical models, we evaluate four EM techniques for use in geothermal exploration: magnetotellurics (MT), controlled‐source audio magnetotellurics (CSAMT), long‐offset time‐domain EM (LOTEM), and short‐offset time‐domain EM (TEM). Our results show that all of these techniques can delineate the clay cap, but none can be said to unequivocally detect the reserv

Within the State of Arkansas, there is an increasing number of aging dams and levees that have little to no documentation concerning their construction or composition.

Techniques such as electrical resistivity tomography, seismic refraction, and electromagnetic induction have been used to image dams and levees.

Three electrical and electromagnetic geophysical methods were used to examine the moisture and permeability distribution and identify fractures in a partially saturated, fractured ash-flow tuff near Superior, Arizona. Experiments using ground penetrating radar (GPR) to locate targets with known orientations in the tuff were used to assess the angular limits of fracture detection from radar profiles. Identification of fractures from radar records appears to be limited to those with dips of less than 45°. The application of a single well electrical tracer (SWET) technique proved effective in

The receiving antennas consist of three mutually orthogonal antennas which are placed on the ground in an arbitrary orientation.

Abstract:
Time Domain Reflectometry (TDR) and other in-situ and remote sensing dielectric methods for determining the soil water content had become standard in both research and practice in the last two decades. Limitations of existing dielectric methods in some soils, and introduction of new agricultural measurement devices or approaches based on soil dielectric properties mandate improved understanding of the relationship between the measured effective permittivity (dielectric constant) and the soil water content. Mounting evidence indicates that consideration must be given not only to the volume frac
