The expedition led by Duke marine scientist Cindy Van Dover found the previously unknown wreck in mile-deep waters on July 12 using an underwater robot and a manned submarine.
They've found artifacts including an iron chain, glass bottles, an unglazed pottery jug and navigational instruments including a metal compass. Archaeologists who examined photos of the artifacts say the wreck appears to date back as far as the late 18th century, which would make it a rare find.
