ABSTRACT OF THE DISCLOSURE A monochromatic interference signal is removed from seismic data records by transmitting into the earth a seismic signal having a null component in its power spectrum at substantially the frequency of the interference signal. When cross-correlation techniques are used to determine subsurface characteristics, the cross-correlation product of the detected signal with the transmitted signal will contain a substantially zero component at the frequency of the interference signal.
