QAR Inspection Dive - August 18, 2004
Chris Southerly 08/20/04
Summary
UAB staff members Richard Lawrence, Chris Southerly, Nathan Henry, and
Julep Gillman-Bryan conducted an inspection of the Queen Anne's Revenge
shipwreck site, August 18, 2004. Winds were light from the south and
seas relatively calm (2-3 feet). Diving conditions were generally favorable
with visibility 4-5 feet between high and slack tide. Hurricane Charley
recently passed just west of the site, August 14, 2004, moving overland
up the North Carolina coast. During the storm, winds in the area measured
37mph sustained, with gusts up to 49mph. Storm surge was estimated at
2-3 feet along the Bogue Banks beaches, and therefore on the QAR site.
The site area shows evidence of scour around the main
pile. Ballast and concretions east of the baseline between 70 and 80
north are again exposed, not seen since after Hurricane Isabel in September
2003. (Figure 1).Cannon C-1 is very exposed, almost completely above
the surrounding sand (Figure 2).Cask hoops and rigging elements to the
southwest side of the pile were also exposed more than previously observed.(Figure
3).Sacrificial planking at the south edge of the pile that is normally
buried was easily visible extending up to 5 feet south covered only
with a light dusting of sand.(Figure 4).Sandbags could be seen along
the north side of the pile at the edge of past excavation areas and
along the east side.(Figure 5). Anchor A-1 was exposed completely down
to the ring and anchor A-3 was exposed almost to the stock. Part of
the wooden stock of anchor A-3 was also exposed just to the north of
the anchor. The area south of BL60 was still sanded in.
Details
The buoy was thrown on the pile coordinates, and RWL entered the water
with a mooring buoy. Once RWL located the site, the mooring line was
fastened to the east screw-eye and R/V Snap Dragon secured to the mooring.
RWL proceeded with general recon and site cleanup. NCH entered the water
with the digital camera to do general recon and document conditions
and site exposure. Once RWL returned, CWS entered the water to take
sand elevations and conduct a visual recon (Figure 6). JGB also conducted
a site reconnaissance and as the last diver in the water, retrieved
the buoy and released the mooring line from the east screw-eye. A single
fragment of stoneware found near the exposed planking south of the pile
was recovered because of the likelihood of it being lost (Figures 7,
8). Detailed sand measurements show a deposition of sand to the north
area of the site, scour in the immediate vicinity of the pile (especially
to the east and south), and a slight sand loss to the south area of
the site (Figure 9).
