Since I don't claim to be an expert in anything. I have a question for side scan sonar experts and experts on coral formations.
A few years ago I was on a side scan sonar survey outside the Fishers permitted area. An investor from another supposed wreck side a few miles away from where the Fishers found the Atocha wanted a survey done.
We went to the GPS numbers of this supposed wreck site. When I met the guy that wanted the survey done, I told him that I knew divers that dove the site with the guy that said there was a wreck there and and they said the only thing there was a flat bottom and no sign of a wreck.
We surveyed about 2 miles on either side of those numbers and came up with nothing but a flat bottom. I then suggested that we survey another 2 to 3 miles out into deeper water. Which put us about 4 or 5 miles away from the GPS numbers we were given and probably 8 to 10 miles away from the Fishers area.
The only thing we came up with was a flat bottom, until we came to one spot that showed a small anomaly. About 10 ft long and 3 or 4 ft high. The side scan operator thought it might be coral. We were in about 250 ft of water.
I'm not sure it was coral, since the bottom was clear every were around it for miles.
Any thoughts on what the anomaly might be? I was only a deck hand on that survey and I was wondering if this might be something other then coral and if I should give the GPS numbers to the Fishers to check out. I still have the numbers on our chart plotter.
Just curious.
