If Andrew is an “expert,” why the hypothesis?
Today’s sub-bottom profiler and the associated computer programs are the cutting edge in locating a submerged wreck. The printout of the reflected bottom with the overburden removed is a fantastic view of a wreck that has been totally encrusted with the remains of the Teredoworms which ate her. In the runs where the profiler picked up the anomaly, it penetrated the crust and further showed the bedrock three feet below. All that remains of the wreck is contained below the “Teredo crust”. Between the crust and the bedrock are the remains of an ancient historical shipwreck.
