A statement on Duke University's website says the team's sonar devices noticed "a dark line and a diffuse, dark area." The team first thought it was a "scientific mooring" they had previously lost in an earlier expedition. Instead, they came upon the underwater mysterious shipwreck.
"This is an exciting find," the team's leader and Duke University's Marine Laboratory director Cyndy Van Dover stated. "Even with major advances in our ability to access and explore the ocean, the deep sea holds its secrets close."
Van Dover said she had led a number of expeditions near the area over the past few years, and was surprised to discover the mysterious shipwreck just days ago.
"It's ironic to think we were exploring within 100 meters of the wreck site without an inkling it was there."
The remains aboard the wrecked ship, including an iron chain, bricks, glass bottles, and navigational instruments "indicate it might date to the American Revolution" or the 19th century, according to Duke University.
