Lonewold 50 - We have no real idea of the sea floor conditions in the search zone, apart from that sea floor mapping done decades ago.
This is one of the most unexplored sea bottom regions in the world.
The best we know is from that old mapping - and that is, that the sea floor in the region largely consists of soft, fine, silty clayey sediments.
Think heavy consistency mangrove mud, under 8000-9000psi pressure.
Personally, I'd be deeply concerned about the suction effect of trying to retrieve any wreckage from such material, after having gained extensive experience in trying to recover items buried deeply, in fine silty clayey sediments, on land!
