In this paper we propose the use of autonomous underwater vehicles to enable faster and cheaper ocean bottom seismic acquisition. Our effort is focused on buoyancy-driven vehicles as this method of propulsion is extremely low-powered, enabling the units to have very long endurance and, therefore, making them suited to seismic acquisition on a large scale. We show that, for development-style surveys, these units can potentially double the acquisition efficiency. Furthermore, their ease of deployment makes them suited to acquisitions purposely designed for velocity estimation via full-waveform inversion, either on their own or in hybrid configuration with a streamer vessel.
