Thanks guys. I also wanted to present a few objects that I spotted that I don’t recall being discussed previously. In the first image (image “4L59.00”) the white circle and arrow shows some object with a tiny box or cutout attached to it. Immediately above it is a nice round hole that, to me, seems like it was there before the object sank. There is a similarly sized half-hole to the right.
The second image (7L08.17) shows a few more interesting things. The white arrow points to a flat, backwards “C” shaped object, the red arrows point to a suspiciously straight ledge, and the green arrow points to a circular object that only became apparent after viewing the image in 3D.
The last thing I saw was a wire rising up from the seabed. I don’t have a screenshot for it yet. It is visible from around 1:22 to 1:56 in the video to the right of the large boulder in the center of the image. As the ROV flies over it, you can see its coiled like the filament in an old light bulb. Seems too rigid to be whip coral.
Oh, and here are a couple side-by-side versions of the images, although I would highly recommend finding a pair of 3D glasses to view the full-res pictures.
