Abstract:
1. A method for marine seismic surveying, comprising: towing a plurality of seismic sensors disposed on a plurality of seismic streamers in a body of water; actuating a seismic energy source in the body of water at selected times; detecting seismic signals at the seismic sensors resulting from the actuation of the seismic energy source; creating a seismic data trace for each of the detected signals; determining at least one Fresnel zone for at least some of the seismic data traces; computing a contribution of each of the seismic data traces to each one of a plurality of bins defined in a predetermined pattern, each contribution based on the Fresnel zone associated with each seismic data trace; based on the computed contributions, determining a maximum lateral distance between longitudinally corresponding seismic sensors on each streamer that will result in a contribution sum in each bin exceeding a selected threshold; and at least one of storing and displaying the maximum lateral distance.
