USCG is Testing Eco-Friendly Moorings for Navigational Buoys

The United States Coast Guard (USCG) uses navigational buoys to direct water traffic and to protect vulnerable benthic ecosystems such as seagrass communities and coral reefs in U.S. waters. However, most buoys are currently attached to the seafloor by concrete anchors, also called sinkers, and heavy metal chains that can have just as significant an impact on marine life themselves.
