Claim Text:
1. A method for seismic prospecting in an aquatic medium using a device comprising at least one seismic cable provided with sensors and at least one moving seismic source, comprising the following steps: moving the cable in the water using two drones each placed at one end of the cable and which maintain tension in the cable that keeps the cable in a quasi-stationary or stationary position, the movement of the cable being restricted by minimizing the deviation of the cable with respect to a desired route in the terrestrial reference frame, the movement of the cable also being restricted by a maximum track curvature value in the water, and, at the same time, moving the seismic source, emitting waves via the seismic source, and sensing reflections of the waves by the cable, wherein at a moment the moving of the cable is performed, one of the two drones sets the cable in motion by orienting the heading by pulling in a first direction, while the other drone pulls in a second direction to maintain a minimum tension in the cable.
