Archaeological Investigations

Side scan sonar, mulitbeam, and marine magnetometer surveys sometimes reveal archaeologically-sensitive features requiring video documentation. Depending on water depth, currents, and visibility, OSI employs either hired divers or an ROV to undertake the video documentation. In challenging environments, the ROV provides an ideal resource for vessel-controlled video documentation. USBL positioning is employed to aid in finding the artifact and then documenting its position.
