Abstract In a first embodiment the invention comprises a method for gathering geophysical data, including towing geophysical data gathering equipment behind a survey vessel in a body of water, said equipment including an array of sensor streamers extending behind said vessel, and determining a geodetic location of a streamer steering reference point at a forward end of the sensor streamers and a reference direction. At least one sensor streamer included in said array of sensor streamers is laterally deflected in response to the determined geodetic location of said streamer steering reference point and the determined reference direction. -12A -12 19, 19 ]1 2-1 17A 18 18 20A 18 18 14 20A 24 24 24 20A 14 24 20 20 20A 20 20 24 22 22 29 29 22 22 23 29 23 23 29 23 29 29 29 29 22 22 22 22 26 26 26 26 26A 26A 26A 26A 22 22 22 22 23 27 23 23 27 23 29 29 29 29 22 22 22 22 26 26 26 26 26A 26A 26A 26A 22 22 22 22 23 23 23 23 29 29 29 29 22 22 22 22 25A 25A 25A 25A 25 25 25 25 |
