The crew and visiting scientists during the assessment project consisted of divers from the UAU, Intersal, MRI, the North Carolina Maritime Museum (NCMM), the University of North Carolina at Wilmington (UNCW), IMS, the University of North Carolina Center for Public Television (UNCTV), and ECU. CFCC provided valuable topside assistance by recording water quality and lifting three of the ship's cannons. Researchers have invested a tremendous amount of field time in assessing the shipwreck. Countless hours have been spent on all phases of the project including planning, historical research, media relationships, and public education. The magnitude of the overall commitment is well reflected in the dive logs from the 1997 and 1998 fall expeditions. During that period of thirty-eight field days, investigators made 832 dives and spent more than 797 hours on the sea floor studying the shipwreck and its surroundings.

A remote sensing magnetometer survey initially located Queen Anne's Revenge. The magnetometer detects variations, or anomalies, in the earth's magnetic field produced by ferrous objects. Additional surveys conducted in the general vicinity of Queen Anne's Revenge located a large anchor 420 feet south of the main site. The anchor may be associated with the shipwreck since it appears to date from the same time period. Side-scan sonar was used on several occasions; however, the low relief and small size of exposed portions of the site presented a negligible image. Sub-bottom penetrating sonar was not attempted because of the shallow deposition of the cultural materials and the underlying densely packed sand bottom.

The main concentration of visible remains found at the site measures 25 feet by 15 feet and includes eleven cannons, two large anchors, a grappling hook, numerous iron cask hoops, several iron deadeye strops used to secure the ship's rigging, a cluster of cannonballs, and a large number of ballast stones and concretions (Figure 6). Divers located a third anchor 50 feet north of the main concentration. The maximum relief above the surrounding seabed is approximately 4 feet, with most of the exposed remains being less than 2 feet.

Test excavations have revealed that buried materials extend to the north anchor. Buried materials observed during explorations on the north side of the exposed wreckage include iron concretions such as cask hoops and unidentifiable objects. A section of wooden hull oriented in a northerly direction from under the mound of exposed wreckage was uncovered and recorded in 1998.

Test excavations also revealed large ballast stones adjacent to the exposed remains on the east side of the site. A probing survey on the west side indicated that cultural remains are confined to within 15 feet of the mound. Excavations to the south exposed additional cannons, bringing the total to eighteen. In that area divers also found a rich collection of small artifacts including numerous lead shot, pewter plates and chargers, intact glass wine bottles, pottery fragments, medical and scientific instruments, and even a few flakes of gold. The extent of the buried cultural deposits has not been determined to the south or west of these test units; however, it is not expected to extend much further, based on the lack of positive contacts during the probing survey.
