<p>A method is disclosed for acquiring seismic data in an area having periodic acoustic interference. A time window in which the periodic acoustic interference is substantially attenuated is sensed. The discharge time of the acoustic source is then adjusted so that the desired portion of the seismic signal produced by the acoustic source arrives at the acoustic receiver within a subsequent time window. The method may be used in a marine environment by configuring a seismic survey vessel's navigation and control system to produce time mode shooting, where the acoustic source is discharged at selected predetermined times, rather than at selected predetermined locations along the vessel's path, and then adjusting the acoustic source discharge time so the desired portion of the seismic signal arrives at the acoustic receiver within a subsequent time window.</p> |
