| October 5, 2010 | Archaeologists seeking ancient booty dive to Blackbeard's pirate ship | | Washington: Archaeologists are once again heading back to the sea off North Carolina's coast in a continuing effort to recover artefacts from the wreck believed to be Blackbeard's flagship. The boat, called Queen Anne's Revenge, is believed to have
sunk in 1718 near Beaufort, N.C. Archaeologists in the state aim to save a dozen
cannons, which are up to 8 feet long and weigh as much as a ton, and the ship's
1,800-pound anchors by preventing the process that corrodes iron in saltwater.
To do so, they apply skinny aluminium rods to the boat that act as anodes, supplying
an electrical charge that inhibits corrosion. "Visibility on the bottom is about
six inches with a dive light and zero without," Fox News quoted a team member
as writing on the restoration effort's Facebook page. "Occasional surge shifts
you back and forth a few feet. Working on repositioning the 6" suction and preparing
to re-expose the grids covered over by last week's weather," the team member
stated.
The Daily News of Jacksonville reported that last week's heavy rain and winds
kept the team from investigating the wreck. QAR archaeological field director
Chris Southerly said the team knew it would lose days due to bad weather. "It's
imperative that we stop the damaging effects of salt water on these treasures,"
Southerly said of the underwater corrosion-prevention process. "This is a good
alternative to help stabilize them when in-laboratory space is not available,"
he stated.
