A method for seismic prospecting in an aquatic medium using a device having at least one seismic cable provided with sensors and at least one moving seismic source. The method includes the following steps: 1) moving the cable in the water using two drones each placed at one end of the cable and which maintain tension in the cable, the movement of the cable minimizing the deviation of the cable with respect to a desired route in the terrestrial reference frame where the movement of the cable is also being restricted by a maximum track curvature value in the water, and, at the same time; and 2) moving the seismic source in a reference frame connected to the cable, emitting waves via the seismic source, and sensing reflections of the waves by the cable.
