A buoy for recording seismic signals while underwater. The buoy includes a body; a buoyancy system configured to control a buoyancy of the body to descend to a predetermined depth (H); a propulsion system configured to actively adjust a position of the body at a given position (X, Y); a seismic sensor located on the body and configured to record the seismic signals; and a control device configured to control the buoyancy system to maintain the body substantially at the predetermined depth (H) and to control the propulsion system to maintain the body substantially at the given position (X, Y) while the buoy records seismic data, and also to instruct the seismic sensor when to record seismic signals.
