Abstract
An improved method and apparatus for detecting telluric noise information while performing induced polarization prospecting. Telluric noise electrodes are positioned on an equipotential line lying about an input current electrode forming part of a conventional IP electrode spread. The telluric noise record obtained from the noise electrodes is essentially free of IP input signal waveform.
