ABSTRACT:
In magneto-telluric geophysical exploration, the earth's electric telluric field in two orthogonal directions is determined. Electrodes are positioned on the earth's surface so that measured potentials between adjacent electrodes measures the earth's telluric field in known directions. These measurements are converted to signals representing the earth's telluric field in two specified orthogonal directions. The measurements are made between electrodes spaced along a cable which is laid on the ocean floor.
