Abstract:
1. A method for acquiring marine seismic data, comprising: towing at least one seismic energy source in a body of water; actuating the at least one seismic energy source at a plurality of spatial positions, a distance between each of the plurality of actuations being randomly different than any other distance, the difference between successive distances being sufficiently large to enable detection of corresponding differences between a position of the at least one seismic energy source corresponding to each actuation using detected seismic signals; recording seismic energy detected by at least one seismic sensor substantially continuously through a plurality of actuations of the at least one seismic energy source, the recording comprising recording a geodetic position of the at least one seismic energy source and the at least one seismic sensor at each actuation; and processing the recorded seismic energy into a discrete shot record comprising a trace corresponding to a recorded signal at an actual position of the at least one seismic energy source and the at least one sensor at each actuation.
