Description:Two submarine cables were installed by plow burial in the seafloor through Olympic Coast National Marine Sanctuary for the Pacific Crossing fiber optic telecommunications system in 1999 and 2000. At the time, there were no published studies on impacts of submarine cable installation to seafloor habitats or biological communities. This made it challenging for resource management and permitting agencies to determine appropriate measures associated with these installations. A reasonable assumption was that the trenching required to bury the cables could disrupt benthic communities. As a result, the authorization to install the cable in Olympic Coast National Marine Sanctuary required post-installation field studies to monitor the impact of cable installation on benthic habitats and biological communities and the extent of recovery over time.
