Abstract
Systems and methods of optical link communication with seismic data acquisition units are provided. The systems and methods can perform at least portions of seismic data acquisition survey. A plurality of seismic data acquisition units can be deployed on a seabed. An optical communications link can be established between an extraction vehicle and at least one of the seismic data acquisition units. A frequency of the at least one seismic data acquisition unit can be syntonized or synchronized via the optical communications link. The at least one seismic data acquisition unit can be instructed to enter a low power state subsequent to syntonizing the frequency of the at least one seismic data acquisition unit. The seismic data acquisition unit can exit the low power state and acquire seismic data in an operational state.
