Oh I've gone through the images many times over, and continue to spot things I haven't noticed before. Nothing that's worthy of posting on the forum,.. yet.... I'm not going to point to out of focus bubbles or sea shells (aka metallic nipples) and ask "what's that?... no you're pointing to the wrong object, but wait that looks interesting too, like a stirrup shape..." ZOOM in and use your reasoning skills to judge before posting. IMO.
Images 568 through 595 intrigue me the most, but I can't quite say why. There's more to see in terms of topography, possibly because they fall within the line, on the new 2015 GPS plot map, that the supposed anomaly was established on the 2012 sonar map. But I still can't attribute these features to the anomaly since I don't know if the camera actually matched up to the GPS coordinates taken from the SURFACE of the water. I also can't discern the 3d dimensional qualities of these features (height/depth) since the images provide only so much 2d information. It's hard to say, at Niku, how much coral can grow on (and obscure) a relatively intact man-made object that's been sitting underwater at 600ft for 75+ years. Could it be totally encrusted over by now??
