This is a pretty good media blitz by Odyssey. Very interesting company. Having invested time in the effort to document (not raid) shipwrecks, I'm not exactly sure what I think about Odyssey. One thing that became clear to me is that the rate of deterioration of a wreck can change after many years. A firm like Odyssey has the incentive to get to wrecks that otherwise would not be discovered, and given the right approach, I do support that. But I digress...
Looking at the side scan, at least what little they allowed to be seen, its hard to draw a firm conclusion. One of the pictures does not seem to show a lot of a relief shadow. I can't form an opinion about how tall this is, but I do think there are some kind of drag marks over it. Hard to image how the circle could form naturally or even as an anomaly. I do believe something is there. I also believe that seeing more of the surrounding detail would reveal more about what is going on there and its pretty obvious to me that's why they are only showing the area right around the circular feature.
One way you could get a circular artifact that way would be to have a cylindrical object (like a submarine) hit the bottom straight up & down and then have the superstructure break in half, leaving a nice neat circular cross section. I've seen that happen with a plane (WWII era Harpoon) that stood on its nose for years and eventually came apart during an earthquake (nisqually). That would certainly leave a similar kind of pattern, but of course you would then see the rest of the remaining wreckage nearby.
Cool stuff. Makes me super interested in Odyssey, which of course is obviously the purpose of the "UFO" article. This kind of exploration requires large dollars and lots of investors.
Hey Odyssey.....do you need a data warehouse guy with a background in shipwreck exploration? I could make some availability for something like that.
