Two more cannons from Blackbeard's Queen Anne Revenge have been brought up from the ocean floor off the Crystal coast.
The fall dive netted researchers cannon balls, rigging gear and sounding weights that were recovered Monday from the Beaufort Inlet. The two smaller cannons, which were used for close firing at ships, were recovered Friday and weigh about 500 pounds each.
The North Carolina Department of Cultural Resources says researchers will work at the site through October and hope to recover four heavier cannons that remain on the ocean floor.
Intersal, Inc., a private research firm, discovered the shipwreck in 1996.
