摘要

Utility companies have been laying pipelines and cables across the ocean floor for more than a century. Prior the introduction of GPS, marking their position was a difficult and tedious task, fraught with error. It is extremely important to know the exact location of existing lines before undertaking dredging operations or when new pipes and cables are laid down. Regulations require they be buried from several feet to several meters under the ocean bottom to prevent snagging by boat anchors and fishing trawls. This depth of burial typically makes them impossible to find with conventional metal detectors. Two pieces of equipment have proved most effective in finding them; a pinpointing magnetometer and a cable tracker. The pinpointing magnetometer is a very sensitive device that locates iron and steel pipes buried up to 16 ft in the bottom, and the cable tracker is powerful enough to detect a power or communications cable at more than 30 ft away.
