INSTRUMENTATION AND TECHNIQUES FOR SIMULTANEOUS MEASUREMENT AND SYNCHRONOUS TRANSCRIPTION OF TELLURICS

Abstract

A program was undertaken to measure and analyze the variations of the telluric fields for a particular band of frequencies. The term telluric field is restricted to the variations with periods of several minutes or less that occur in the earth's electric field. An experimental project was initiated to measure and record the variations simultaneously at two sites. Later, these recorded data are synchronously transcribed onto one magnetic tape in preparation for analysis. This analysis describes the instrumentation of the mobile measuring system, the transcription system, and the operational techniques that are used to make the measurements and transcriptions.
