Paper Abstract

A methodology and system is presented for phenomenological research for near and far-field data collection, processing, and analysis of seismic, acoustic, and electromagnetic signatures associated with facilities in operation or under construction. A discussion of sensor selection and positioning considers the signature sources, the background environment, the signal propagation media, and the signal levels of interest. To acquire data of sufficient quality for robust analysis, the Enhanced Field Data Acquisition Logging sensors (EFDALS) system is utilized, providing a rugged and portable, high-fidelity digital recording capability. This system, comprised of a variety of transducers, front-end signal conditioners, digitizers, and digital audio tape recorder, has been integrated with the data reduction, processing, and archiving capabilities developed during seven years of reliable data acquisition.
