How long are wrecks estimated to last down there? I'm talking with sediment build up and so forth? Of course, the water will most likely preserve the wreck, but how long can it last before it gets covered up? I ask because I'm picturing a future where we're long gone and someone else is discovering out ruins and piecing together our society from what we've left behind.
I know we've found boats (like that one found in the Solent) from a very long time ago on the ocean floor. Of course, with this wreck being a giant hunk of metal, I'm sure it'll be relatively easy to locate even when buried by sediment.
This video has some interesting information on the deterioration of the Titanic, I imagine a similar thing would be happening in this case. Spoiler: seems like the Titanic will essentially be totally gone in about 1000 years due to deterioration from bacteria that create a byproduct from metabolism that corrodes the iron.
