Title: 2012 Debris Field in 3D
Post by: Byron Ake on July 02, 2013, 03:10:24 PM
Hello everyone! Short time lurker first time poster here. First, I must say that I am really impressed by the forum, especially the way we can communicate directly with Ric and discuss developments even before it is officially posted to the TIGHAR home page.

After watching the Debris Field footage on YouTube a few dozen times I decided to try to grab a few frames and put them together to create a 3D effect. The results are shown below. Please note that I have absolutely no experience with 3D photography and that this video was not shot with 3D in mind, so the results are not optimal. You will need a pair of anaglyph (red/cyan) glasses to view the photos. I will try to post some side-by-side photos later for those who want to try the cross-eye method. I have also done some very basic processing on the images to better show the detail. Any comments?

If I may, in 3D, these two objects look man-made and nearly identical:

They look more similar in his excellent image than in mine for some reason.

Nice job Byron,  possible manmade semiburied object with right angle and larger object appears manufactured.

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.

Byron, could be a length of pipe or tubing, with an open butt end, intersecting your circle at 10:30 position on 4L59, can you post it minus the circle please?

I keep coming back to this on the video and these pictures for months now!

Is there anybody else that sees the guts of a radial engine, with the aluminum parts of the engine dissolved and the rods surrounding the hub splayed out ?
In which case does anyone else see a section of carb heat shroud at the top...stainless and half round from the top of the engine?
(Flew an Otter with a 1340 for years, and that is how they are arranged; the cylinders and the cases dissolve first and leave a cluster of rods after a long time...carb heat shroud lasts as it's stainless.)

Okay...just wanted to say it !?!

The stuff that looks like wire could also be some of that stiff  old style plastic/rubber stuff called koroseal; we used to tie stuff to the engine and landing gear with it...as I remember it's square...I've promoted this before but unsuccessfully !

With no idea of size, other than that fish, I am suckered in every time I watch the utube...

Had to ask...the engine and wheel of at least one side could logically be adjacent.

Just so you'll know I'm not as immune to conjecture as I pretend to be...(off to bed now!

Bill

I really hope you guys are right and Jeff Glickman agrees with you that there are man-made objects there, but I have to say that spending day after day in the control van of the ROV last summer made me pretty cynical about identifying odd shapes as man-made objects.  I can't tell you how many times we saw something really interesting, went over and looked closely at it, and said, " Oh, I see. It's only coral."  After a few hundred of those you learn to be careful about what you think you see. 

In my experience - including my experience at Niku - man-made objects underwater hit-you-up-side-the-head-with-a-two-by-four.  They're not coral-encrusted suggestive shapes. Take a look at the airplane parts in Lessons from a Buffalo (http://tighar.org/Publications/TTracks/2013Vol_29/February_2013/Lessons_From_A_Buffalo.pdf).  That's what 70+ year old airplane debris in a coral reef environment looks like.

Ric

All the video's i have watched, I have not come across 2 objects that are the same with same feature's apart from rocks or plant's,

Can you show me a plant that matches the two objects top left of this image ?

I have no idea whether those objects are coral or plant material but I see no indication that they are man-made.

I'm having trouble bringing up this Buffalo reference. Link correct?

Works for me.  It's a pdf of an article that appeared in the March 2013 issue of TIGHAR Tracks.  You can also get to it by going to:

What a difference tumbling an additional 975 feet (985-10) can make to the integrity of an aircraft.

Well in the first two with the red tones...they are the same as in the video but without the red of course...
I don't know how to do the arrows and that sort of thing...but it's been identified with yellow arrows in the past...it's been nudging me for a long time; I even sent Jeff G. some pictures of radials that were relics from being on a saltwater beach...but before i learned how to post on here so not even sure if they ever reached him...I sent them email.
If it comes under discussion again I'll leap on it !!
But right now it's not worth zero-ing in on, probably....it would be noticeable in that 3D picture if it really is there. (But not something people would recognize unless familiar with dis-assembled radial engines).

Here is a crop of that pipe-like object. I’m not convinced it is man made though. In fact, after studying the images further I find myself rethinking some of the objects I highlighted earlier, especially the shelf (red arrows) in the second image. I found another very similar feature toward the end of the video so I am no longer considering it man-made, although the reverse “C” and small box features still intrigue me.

Yes, that coral is tricky. The only experience I have at discerning coral from man-made stuff is what has been posted on this website. This must be the worst environment (other than say, a thermal vent) to search for 75 year old airplane parts in.

Without stirring up too much more debate, I also wanted to mention the “wheel” just down the slope in the video. I believe it is an illusion. I have nothing solid to prove it- it just seems to me to be awkward if you watch the video thinking it is a wheel and tire, even a deflated one. In the 3D rendering, it doesn’t have much depth, and I don’t see any hard border between the sand (or whatever you call the white stuff) and the object. Looks to me to be a shadow. That shadow part appears sunken in, but it might be just because there is no information there for the brain to interpret. Unfortunately the parallax is horrible in this image, even worse than the others. If you watch the video, as the ROV flies over the object, you get the impression that it is not very wide. Also the scale is off. If the object were 3 ft in diameter like an Electra wheel the ROV would have to be moving pretty quickly. I’d be very interested to know what Jeff or other experts see in the 3D images. Well worth the few bucks for the glasses IMHO.

I'm trying to stay on Topic - ha.  Would it be possible to see more of the debris field video then the piece currently up there?

That's the entire clip.

Thanks John.  This illustrates to an even greater extent than the Buffalo, "In my experience - including my experience at Niku - man-made objects underwater hit-you-up-side-the-head-with-a-two-by-four.  They're not coral-encrusted suggestive shapes."
