“…The prototype Geometrics OhniMapper was tested and data were cômpared to that collected with the traditional galvanic system by Aunga with excellent results. The OhniMapper resuits had a consistent upward bias when compared to the Auriga measurements and the system is very sensitive to coupling when small dipole antenna (25 m) are used, but data acquisition rates are very rapid.. Two-dimensional IP inversion resuits of dipole-dipole data are spectacular (Frangos, 1997) in defining the waste. The resistivity resuits mapped conductivity variations in both the host and the waste.…”

A baseline study in electromagnetic (EM) exploration of the shallow subsurface (< 10 m) was performed at the Idaho National Engineering Laboratory (INEL) Cold Test Pit (CTP) for the purpose of identifying and evaluating existing commercial and expenmental instrumentation, integrating those technologies with multidimensional interpretational algorithms, and identifying gaps in shallow subsurface EM imaging technology. Rapid magnetic field systems are excellent anomaly detectors. Electric field measurements are necessary to support eurrently available multidimensional inversion. A three-component time-domain dataset appears to have a significant amount of information for three dimensional inversion, but no such algorithms have been identified. The eleven systems, filling the geophysical sounding range from ground penetrating radar (GPR) to lowfrequency electrical geometrical techniques are represented in this study as shown below. All data and survey descriptions are available on the world wide web at http://vetem.lbl.gov . Educators and students are encouraged to use the data.

“…Two goals of the study are (1) identifying methods for acquiring data that can support multidimensional inversion, and (2) that the data will be interpreted many times by different individuals and groups. Interpretation of the data is not the intention of this paper, but inversion results are an important part of the overall study: Alumbaugh and Newman (1997) are performing multidimensional inversion of data acquired with the loop-loop Slingram frequency domain method ;Frangos, (1997) has been working with colleagues on the induced polarhation data; and Tezkan and &her (1997) are performing 2-D inversion on data collected with the plane wave (magnetotelluric) method utilizing radio sources. Tests with the application of 1D inversion on the loop-loop data resulted in a model showing conductive bedrock at depth instead of a shallow conductora classic response for the case of 1D inversion over a highly 3D target.…”

The electromagnetic integrated demonstration (EMID) is a baseline study in electromagnetic (EM) exploration of the shallow subsurface (e 10 m). Eleven distinct EM systems, covering the geophysical spectrum, acquired data on a grid over the Idaho National Engineering Laboratory (INEL) Cold Test Pit (CTP). The systems are investigated and evaluated for the purpose of identifying and reviewing existing geophysical charactefiation instrumentation (commercial and experimental), integrating those technologies with multi-dimensional interpretational algorithms, and identifying gaps in shallow subsurface EM imaging technology. The EMlD data, are valuable for testing and evaluating new interpretational software, and developing techniques for integrating multiple datasets. The experimental field techniques shows how the acquisition of data in a variety of array configurations can considerably enhance interpretation. All data are available on the world wide web (http://vetem.lbl.gov). Educators and students are encouraged to use the data for both classroom and graduate studies. The purpose of this paper is to explain why, where, how and what kind of data were collected. It is left to the reader to assess the value of a given system for their particular application. Information about the EMID is organized into two general categories: survey description and system evaluation.
