Thanks Rick. Just made myself seasick watching, rewinding, rewatching, and trying to track the object as it comes into view, lurches back out of view off the right side of the screen (at 0:55), and then comes back into view. The shape I thought I was seeing definitely ends up morphing into something else as the ROV moves closer and over it (at a different angle from the view provided in the original still shot). I guess the perceived "anchor shape" ends up being a bit of an optical illusion, and it loses that linear appearance after the vantage point shifts.
Indeed, at the risk of stating the obvious, the coral and other growth on that bottom makes it very difficult to discern objects. I'm actually having a hard time perceiving the possible "man-made" objects delineated by the arrows as non-natural things. I could see where the top yellow arrow on the right might presumably equate to the worm gear (?), but how did Jeff pick the stuff in this shot out as being non-natural? Apologies if I'm asking something that's already answered somewhere, but is there a write-up (or discussion) somewhere here on the site that "breaks down" what we think is visible in this debris field photo, and why these objects might fit the criteria of being man-made? Do they seem to match up with specific components on the Bevington object? Just curious as to what specific attributes of the noted objects makes Jeff 100% confident that they aren't natural?
Thanks for tolerating the newbie!
