A marine acoustic source system for generating an acoustic wave in a body of water, the marine acoustic source system comprising a first marine acoustic source array having first and second external source sub-arrays, each sub-array including one 5 or more individual source elements and a cable connecting to a vessel; a first actuator device connected to the first external source sub-array; a first rope connecting to the first actuator device to a first lead-in that is configured to connect to a head of a streamer; wherein the first actuator device is configured to control a length of the first rope in order to control a position of the first source array relative to the streamer; and a o deflector connected to the second external source sub-array and configured to maintain a distance between the first and second external source sub-arrays substantially constant when a length of the first rope varies. |
