When they were mapping the area, I understood they were using some kind of sonar like equipment that would bounce some kind of reflection off from anything on the sea floor. They would then calculate the depth and eventually a relief of what the bottom looked like. Would that work something like a fish finder??
I'm no expert on this subject, but that's my impression, yes -- the system works very much like a fish finder, except that it produces images with much higher resolution... enough, presumably, to reveal wreckage on the sea floor. I'm not aware of an anomalous finding in previous mapping... sounds interesting! if it's not too much trouble and you can remember where you saw that, could you please provide a source?
