Abstract: A method includes receiving data representing measurements acquired by seismic sensors in response to energy that is produced by shots of a seismic source. The energy that is produced by the seismic source for each shot includes a plurality of discrete frequencies of discrete frequency bands that are within a frequency range of interest and are separated by at least one excluded frequency or frequency band. The data may be processed to determine at least one characteristic of a geologic structure.

Abstract: A technique includes towing at least one seismic source in connection with a survey of a structure; and operating the seismic source(s) to fire shots, where each shot is associated with a frequency sweep. The technique includes varying phases of the frequency sweeps from shot to shot according to a predetermined phase sequence to allow noise in an energy sensed by seismic sensors to be attenuated.
