Sonar reading taken by the Navicula in 1988, highlighting the anomalous sonar targets |
The target of the dive are the anomalous sonar targets detected by a survey ship called the "Navicula" in 1988, operating on behalf of the Bedford Institute of Oceanography. The targets were described as "may not be boulders". What is compelling about these sonar targets is that they reside on or near the presumed path taken by the "dark object" on that evening on October 4, 1967, when the "dark object", apparently under its own power, exited Shag Harbour, and ultimately, turned northward towards Shelburne about 27 km away.
The targets highlight something on the seabed which appears to be inconsistent with the rest of the seabed surrounding these anomalies. The dive on July 20 was executed to determine the diving conditions in that part of the coast, and to possibly discover the anomalous sonar targets. Both objectives were satisfied, although, only two of the four targets were discovered and therefore, remains inconclusive.
