B022 IMPROVING SIGNAL-TO-NOISE IN ELECTRICAL AND EM METHODS WITH SENSOR ARRAYS Abstract 1 The accuracy and depth of information of electrical and electromagnetic geophysical surveys is largely determined by the limits of signal detection. Many of these surveys today employ multiple sensors to collect data efficiently. However the use of multiple sensors can also be exploited to improve the signal fidelity from each sensor which translates to more accurate geological models and greater depth of investigation. In this paper we present a two step algorithm for the removal of harmonic noise and atmospheric transients the first step is the removal
