At the beginning of July in 2014, E/V Nautilus dove on an unknown sonar target, thought to be a 500 foot-long shipwreck. After a survey of the wreck with ROV Hercules, the Corps of Exploration successfully identified the vessel as USS Peterson (DD-969). Learn more about the dive in photos, or in this blog post.
This expedition focused on documenting the myriad natural and cultural resources that lie in U.S. waters for the joint National Geographic and 60 minutes television special, The Unknown America. Some exploration sites visited include brine pools, deep-water coral reefs, and several shipwreck sites. These include German U-boat U-166 & Robert E. Lee.
