Centuries-old ship discovered off NC coast

Scanning sonar from a scientific expedition has revealed the remains of a previously unknown shipwreck more than a mile deep off the North Carolina coast.

Artifacts on the wreck indicate it might date to the American Revolution.

Marine scientists from Duke University, North Carolina State University and the University of Oregon discovered the wreck on July 12 during a research expedition aboard the Woods Hole Oceanographic Institution (WHOI) research ship Atlantis.

They spotted the wreck while using WHOI’s robotic autonomous underwater vehicle Sentry and the manned submersible Alvin. The team had been searching for a mooring that was deployed on a previous research trip in the area in 2012.

Among the artifacts discovered amid the shipwreck’s broken remains are an iron chain, a pile of wooden ship timbers, red bricks (possibly from the ship cook’s hearth), glass bottles, an unglazed pottery jug, a metal compass, and another navigational instrument that might be an octant or sextant.

The wreck appears to date back to the late 18th or early 19th century, a time when the United States was expanding its trade with the rest of the world by sea.

“This is an exciting find, and a vivid reminder that even with major advances in our ability to access and explore the ocean, the deep sea holds its secrets close,” expedition leader Cindy Van Dover, director of the Duke University Marine Laboratory, said in a statement.

“I have led four previous expeditions to this site, each aided by submersible research technology to explore the sea floor — including a 2012 expedition where we used Sentry to saturate adjacent areas with sonar and photo images,” Van Dover said. “It’s ironic to think we were exploring within 100 meters of the wreck site without an inkling it was there.”

“This discovery underscores that new technologies we’re developing to explore the deep-sea floor yield not only vital information about the oceans, but also about our history,” said David Eggleston, director of the Center for Marine Sciences and Technology (CMAST) at NC State and one of the principal investigators of the science project.

James Delgado, director of the Marine Heritage Program, notes that the wreck rests along the path of the Gulf Stream, which mariners have used for centuries as a maritime highway to North American ports, the Caribbean, the Gulf of Mexico and South America.

“The find is exciting, but not unexpected,” he said. “Violent storms sent down large numbers of vessels off the Carolina coasts, but few have been located because of the difficulties of depth and working in an offshore environment.”

Bob Waters of WHOI piloted Alvin to the site of the newly discovered shipwreck after Sentry’s sonar-scanning system detected a dark line and a diffuse, dark area which they thought could be the missing scientific mooring. Bernie Ball of Duke and Austin Todd of NC State were aboard Alvin as science observers.

The expedition has been focused on exploring the ecology of deep-sea methane seeps along the East Coast. Van Dover is a specialist in the ecology of deep-sea ecosystems that are powered by chemistry rather than sunlight, and Eggleston studies the ecology of organisms that live on the seafloor.

“Our accidental find illustrates the rewards — and the challenge and uncertainty — of working in the deep ocean,” Van Dover said. “We discovered a shipwreck but, ironically, the lost mooring was never found.”
