Sound Evidence: Historic shipwrecks and landscape emerge and are protected using sidescan sonar.

摘要

During the dark hours of an early summer night thieves worked quickly on the shipwreck site, blowing a large hole in the sea floor with their propwash deflector. After exposing a pile of cannon, anchors, and other wreckage, they laid their target open like a wound, ready for looting. Divers used hand-held sledges to pound on the cannon to see if any were made of bronze, and after ascertaining that they were all iron, they selected two for removal. They used lift bags or a derrick cable to break the guns away from their 235-year-old resting place and loaded them onto a boat. Only weeks later, divers from the Lighthouse Maritime Archaeological Program (LAMP) in St. Augustine, Florida encountered the looted site and reported the theft to local and state authorities.
