RE: Oak Island Coring Project: Central Area Analysis
Dear Ms. Finegan and Mr. Bernstein,
Post Office Box 2494
5290 River Road
Washington NC 27889-2494
I would like to confirm that Tidewater Atlantic Research (TAR) reviewed the 173-statute
miles of magnetometer and sonar data GeoDynamics recently collected in the central area
off Oak Island (Figure 1). Analysis of the magnetometer data identified 149 anomalies
(Figure 2; Appendix A). All 149 signatures appear to be generated by debris. None of
those magnetic anomalies have signature characteristics indicative of association with
vessel remains. Likewise, the 18 sonar targets (Figure 3; Appendix B) represent debris and
bottom surface features. Based on the magnetometer and sidescan sonar data TAR
reviewed, no shipwreck remains are located in the survey area.
Best regards,
Gordon P. Watts, Jr., Ph. D, RPA
Director
