1. A method for gathering geophysical data, comprising:

  • towing geophysical data gathering equipment behind a survey vessel in a body of water, the equipment including at least one geophysical source and an array of sensor streamers extending behind the vessel;

    determining a geodetic location of a first steering reference point at a forward end of the sensor streamers;

    determining a reference direction based on the first steering reference point and a selected location on the survey vessel; and

    laterally deflecting both at least one sensor streamer included in the array of sensor streamers and the at least one geophysical source, wherein the laterally deflecting is based on the determined geodetic location of the first steering reference point and the determined reference direction.
