Abstract

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