An autonomous underwater vehicle (AUV) for recording seismic signals during a marine seismic survey. The AUV (200) includes a body (204) having a flush shape; a buoyancy system (202) located inside the body and configured to control a buoyancy of the AUV while traveling underwater; a processor (108) connected to the buoyancy system and configured to select one of plural phases for the buoyancy system at different times of the seismic survey, wherein the plural phases include a neutral buoyancy, a positive buoyancy and a negative buoyancy; and a seismic sensor (110) for recording seismic signals.
