The team gained incredibly detailed data by conducting laser line-scanning surveys of both ships, followed by successful photogrammetric modeling to generate three-dimensional images. Using manned submersibles the researchers were able to access the sites of both shipwrecks, and caught the first sight of the vessels since the day they sank 74 years ago.ĭiagram (top) and sonar image (below) of U- 576. A multi-agency interdisciplinary team of researchers embarked upon a productive and rewarding 15-day expedition to visit the wrecks, which sit 40 miles offshore under 700 feet of water, and were successful in their mission to virtually recreate the underwater battlefield. In August and September, archaeologists revisited the maritime legacy of North Carolina's Outer Banks in a successful effort to explore the remains of a World War II convoy battlefield consisting of two vessels, U- 576 (a German submarine) and Bluefields (a Nicaraguan merchant ship that was part of an Allied convoy). Read on for the second part in a series about the expedition. This summer, archaeologists from Monitor National Marine Sanctuary explored the remains of a World War II convoy battlefield.
