Abstract
Systems and methods of performing a seismic survey in a marine environment are provided. The system includes a seismic data acquisition unit disposed on a seabed in the marine environment. The seismic data acquisition unit includes a local pressure sensor, an optical transmitter and an optical receiver to determine one or more pressure values. The system includes an extraction vehicle including a reference pressure sensor, an optical transmitter, and an optical receiver to establish an optical communications link with the seismic data acquisition unit, and generate reference pressure data. The system includes at least one of the local pressure sensor and the one or more pressure values calibrated based on the reference pressure data generated by the extraction vehicle.
