Wreck of the RMS Titanic the debris field was surveyed in Robert Ballard's 1986 expedition, pairs of shoes were observed lying next to each other on the sea bed. The flesh, bones, and clothes had long since been consumed but the tannin in the shoes' leather had apparently resisted the bacteria, leaving the shoes as the only markers of where a body had once lain. Ballard has suggested that skeletons may remain deep within "Titanic"s hull, such as in the engine rooms or third-class cabins. This has been disputed by scientists, who have estimated that the bodies would have completely disappeared by the early 1940s
Wreck of the RMS Titanic of the University of Seville in Spain, has determined that the wreck of "Titanic" will not exist by 2037 and that preservation of "Titanic" is impossible. "Unfortunately, because Titanic is 2.3 miles down, it is very difficult or impossible to preserve. It is film which will preserve it for history now," says Mann. "It has already lasted for 100 years, but eventually there will be nothing left but a rust stain on the bottom of the Atlantic... I think Titanic has maybe 15 or 20 years left. I don't think it will have too much longer than that." Other scientists
