Abstract
In seismic surveys at sea a system for maintaining the sources of seismic energy (2) at the same level when emitting their signals includes sensors (5) provided close to the sources of energy (2) for emitting signals representing pressure conditions and/or motion transmitted to a control unit (9). These signals are compared by control unit (9) for controlling driving devices (6) for the suspension lines (3) for the sources of seismic energy (2), so that their distances from the surface of the sea may be controlled to keep all sources (2) at the same level.
