I believe that a relative depth of one area that is adjacent to an adjoining area of a different depth may be resulting in sharp contrasts of light and dark resulting from reflection of light missing the areas that are darker because they are deeper. I think this could be coming into play in the area with the 'rope' looking pattern. I just think this is contributing to what is being seen in the picture of at least the 'rope' area. Could the concentric nature of the'rope' be the result of the concentric structue of some coral.

Jeff, the wire/rope in the video appears to be a benign object that some have speculated has nothing to do with whatever it is caught up in. Fishing cable, wire trace etc... Yet it is threaded through whatever it is down there. If it is coral playing tricks on us then somehow the coral has managed to slide on top of or, grow around certain stretches of the wire/rope but not others. At some points the wire/rope is found settled in-between 2 parallel strips of coral, 3 occasions, and appears to have become attached to the coral by a round black object at one point.
Who knows what is down there? For sure it isn't nothing. We shall see very soon IMHO

Jeff, Thanks very much. As it turns out, you just happen to be the person I believe I need to contact. I've tried sending a copy of the photo that you posted on January 7, 2012, to info@Mote.org, Mote Marine Laboratory, however, each time I try they email me saying there is no attachment. I was going to see if they would respond as to what is in the photo. Maybe you, or someone, want to give it a try? Thanks again.

Not sure if this is the best place for this question but it is relevant to the ROV search.  Has any attempt been made to model the flow of water over and down the the reef?  In particular I am thinking about the outflow from the lagoon after storms or high tides. The "landing strip" area is not far from the main channel and that flow should move materials on the upper reef during periods of drainage.  I think the NC shelters the "landing strip" somewhat from the channel but it still may influence the distribution of debris down the reef face and may need to be taken into account in terms of the area to be searched.

Hi Matt-----glad to have you amoungst us!
I think that maybe andrew can answer that----I believe I was told that the outflow moves southeast, from left to right. The NC is northwest of the lagoon channel, so i'm thinking any from there might be downstream, maye closer to the landing channel---or maybe alittle bit further?????

Matt / Tom 

I think I'll post a reply in the "Lagoon as catchment basin" thread.  I don't want to distract you guys from finding all those chunks of coral.  :-)

Matt, if you can imagine a section of aircraft skin finally being freed from the superstructure it was once fastened to then it would be at the mercy of the tides/currents/storms etc...
Being lightweight and thin by it's very nature plus, a large area in comparison to it's thickness, it would not take much to set it on it's way.
The main problem with sections of aircraft skin being washed up on the Pacific Islands during this era is that WW2 was raging and there were an awful lot of aircraft around at that time in the Pacific theatre of operations. So a lump of aircraft skin turning up on an island could have come from hundreds of sources. If WW2 hadn't got in the way (bad timing) then a lump of aircraft skin being washed up on a Pacific Island during this era would have stuck out like a beacon.
That's just my opinion of course and, is open to debate (no more discussions on philosophy please, try and keep the thread on topic)
To recap:
WW2= lots of sources of wreckage
No WW2= one source of wreckage?

I do hope this is just 'lumps of coral'
