Abstract
Harmonic noise generated by power lines and electric railways has plagued geophysicists for decades. The noise occurs as electric and magnetic fields at the fundamental frequency of power transmission (typically 60 Hz in North America) and its harmonics. It may be recorded directly during time-domain measurements of electric and magnetic felds, or indirectly, by geophone cables during the acquisition of seismic data.
