The hulking wreck has been a regular destination for divers but a riddle to historians: What ship came to rest in 85 feet of water 10 miles off Absecon Inlet along New Jersey's coastline ?
Now, federal officials have an answer.
The National Oceanic and Atmospheric Administration announced today that it has confirmed that the ship is the Robert J. Walker, an iron-hulled steamer doing mapping work for the U.S. Coast Survey that sank 153 years ago after a violent collision with a 250-ton schooner.
Twenty sailors aboard the Walker died, making it the worst accident in the history of the U.S. Coast Survey or its successor, the National Oceanic and Atmospheric Administration.
The wreck was discovered by fishermen in the 1970s but its identity was a mystery until June when a NOAA ship conducting surveys for navigation safety in the aftermath of Superstorm Sandy made a positive identification. Retired NOAA Capt. Albert Theberge and Joyce Steinmetz, a Ph.D. candidate in maritime archaeology at East Carolina University, provided impetus for the project.
"It's estimated there are 3 million shipwrecks in the waters of the world," said James Delgado, director of maritime heritage for NOAA's office of national marine sanctuaries. "You can't go out and look for every one, but sometimes the situation arises when you have an opportunity to do that. This was a perfect convergence of opportunity."
