Claim Text:
1. A method of performing seismic exploration in an aqueous medium, comprising: receiving, by an ocean bottom seismometer (OBS) unit disposed in the aqueous medium, sub-aqueous environmental data; converting, by a data conversion module of the OBS unit, the sub-aqueous environmental data into an optical signal having a first format configured for optical transmission in the aqueous medium; establishing, via the OBS unit and at least one of a remotely operated vehicle (ROV) and an autonomous underwater vehicle (AUV), an optical link through the aqueous medium determining, by at least one of the OBS unit, the ROV, and the AUV a characteristic of the aqueous medium based on the optical link established via the OBS unit and the at least on of the ROV and the AUV; adjusting, by the OBS unit, a parameter associated with the optical signal based on the characteristic of the aqueous medium; transmitting, by an optical transmitter of the OBS unit via the optical link through the aqueous medium established by the OBS unit and the at least one of the ROV and the AUV, the optical signal in the first format, the parameter of the optical signal transmitted through the aqueous medium adjusted based on the characteristic of the aqueous medium; receiving, by an optical receiver of the at least one of the ROV and the AUV, the optical signal transmitted through the aqueous medium via the optical link; converting, by the at least one of the ROV and the AUV, the optical signal transmitted through the aqueous medium into a non-optical signal having a second format; and transmitting the non-optical signal in the second format from the at least one of the ROV and the AUV to a marine vessel.
