Wreck of the RMS Titanic intact and undamaged dresser behind it. Robert Ballard has suggested that areas within the ship or buried under debris, where scavengers may not have been able to reach, may still contain human remains. According to Charles Pellegrino, who dived on "Titanic" in 2001, a finger bone encircled by the partial remains of a wedding ring was found concreted to the bottom of a soup tureen that was retrieved from the debris field. It was returned to the sea bed on the next dive. The longest-lasting inhabitants of "Titanic" are likely to be bacteria and archaea which have colonized the metal
Wreck of the RMS Titanic extreme pressure would have compressed the bodies into gelatinous lumps. (In fact, this was incorrect. Whale falls, a phenomenon not discovered until 1987 – coincidentally, by the same submersible used for the first manned expedition to "Titanic" the year before – demonstrate that water-filled corpses, in this case cetaceans, can sink to the bottom essentially intact. The high pressure and cold temperature of the water would have prevented significant quantities of gas forming during decomposition, preventing the bodies of "Titanic" victims from rising back to the surface.) In later years, numerous proposals were put forward to salvage "Titanic". However, all
