1. A method, comprising:

  • towing a plurality of sensor streamers behind a vessel in a body of water, wherein a forward end of each sensor streamer is associated with a respective lateral distance D from a centerline of the vessel;

    controlling the plurality of sensor streamers in a first survey mode which includes;

    determining, for each sensor streamer, a desired deflection force for a plurality of deflector devices located at different points on that sensor streamer, wherein the desired deflection force is determined according to a monotonically increasing function of the lateral distance D for that sensor streamer; and

    applying, to the deflector devices of each sensor streamer, the corresponding desired deflection force.
