Wreck of the Titanic
The wreck of British ocean liner RMS Titanic lies at a depth of about 12,500 feet (3,800 metres; 2,100 fathoms), about 325 nautical miles (600 kilometres) south-southeast off the coast of Newfoundland. It lies in two main pieces about 2,000 feet (600 m) apart. The bow is still recognisable with many preserved interiors, despite deterioration and damage sustained by hitting the sea floor; in contrast, the stern is heavily damaged. The debris field around the wreck contains hundreds of thousands of items spilled from the ship as she sank.
The Titanic sank on April 15, 1912, after striking an iceberg during her maiden voyage. Numerous expeditions unsuccessfully tried using sonar to map the seabed in the hope of finding the wreckage. In 1985, the wreck was located by a joint French–American expedition led by Jean-Louis Michel of IFREMER and Robert Ballard of the Woods Hole Oceanographic Institution, which was made possible in part by support secured after their successfully finding two nuclear Cold War submarines at the request of the US Navy. The wreck has been the focus of intense interest and has been visited by numerous tourist and scientific expeditions, including by the submersible Titan, which imploded near the wreck in June 2023, killing all five aboard.
Controversial salvage operations have recovered thousands of items, many of which have been conserved and put on public display. Many schemes have been proposed to raise the wreck, including filling it with ping-pong balls, injecting it with 180,000 tons of Vaseline, or using half a million tons of liquid nitrogen to encase it in an iceberg that would float to the surface. No plan on how to raise the remains of the ship has ever come to fruition, all defeated by the immense cost of even attempting it, impracticality of the suggested method, the vast depth at which the ship rests, or all three. Most significantly, after more than 100 years on the ocean floor, the wreck is too fragile to be raised, and it is protected by a UNESCO convention.
Almost immediately after the Titanic sank on 15 April 1912, proposals were advanced to salvage it from its resting place in the North Atlantic Ocean, despite her exact location and condition being unknown. The families of several wealthy victims of the disaster – the Guggenheims, Astors, and Wideners – formed a consortium and contracted the Merritt and Chapman Derrick and Wrecking Company to raise the Titanic. The project was soon abandoned as impractical as the divers could not even reach a significant fraction of the necessary depth, where the pressure is over 6,000 pounds per square inch (40 megapascals),[dubious – discuss] about 400 standard atmospheres. The company considered dropping dynamite on the wreck to dislodge bodies which would float to the surface, but finally gave up after oceanographers suggested that the 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 crewed expedition to the Titanic the year before – demonstrate that water-filled corpses, in this case cetaceans, can sink to the bottom essentially intact. The high pressure and low 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 the Titanic. However, all fell afoul of practical and technological difficulties, a lack of funding and, in many cases, a lack of understanding of the physical conditions at the wreck site. Charles Smith, a Denver architect, proposed in March 1914 to attach electromagnets to a submarine which would be irresistibly drawn to the wreck's steel hull. Having found its exact position, more electromagnets would be sent down from a fleet of barges which would winch the Titanic to the surface. An estimated cost of US$1.5 million ($35.5 million today) and its impracticality meant that the idea was not put into practice. Another proposal involved raising the Titanic by means of attaching balloons to her hull using electromagnets. Once enough balloons had been attached, the ship would float gently to the surface. Again, the idea got no further than the drawing board.
In the mid-1960s, a hosiery worker from Baldock, England, named Douglas Woolley devised a plan to find the Titanic using a bathyscaphe and raise the wreck by inflating nylon balloons that would be attached to her hull. The declared objective was to "bring the wreck into Liverpool and convert it to a floating museum". The Titanic Salvage Company was established to manage the scheme and a group of businessmen from West Berlin set up an entity called Titanic-Tresor to support it financially. The project collapsed when its proponents found they could not overcome the problem of how the balloons would be inflated in the first place. Calculations showed that it could take ten years to generate enough gas to overcome the water pressure.
A variety of proposals to salvage the ship were made during the 1970s. One called for 180,000 tons of molten wax (or alternatively, Vaseline) to be pumped into the Titanic, lifting her to the surface. Another proposal involved filling the Titanic with ping-pong balls, but overlooked the fact that the balls would be crushed by the pressure long before reaching the depth of the wreck. A similar idea involving the use of Benthos glass spheres, which could survive the pressure, was scuppered when the cost of the number of spheres required was put at over $238 million.
An unemployed haulage contractor from Walsall named Arthur Hickey proposed to encase the Titanic inside an iceberg, freezing the water around the wreck in a buoyant jacket of ice. The ice, being less dense than liquid water, would float to the surface and could be towed to shore. The BOC Group calculated that this would require half a million tons of liquid nitrogen to be pumped down to the sea bed. In his 1976 thriller Raise the Titanic!, author Clive Cussler's hero Dirk Pitt repairs the holes in the Titanic's hull, pumps it full of compressed air and succeeds in making it "leap out of the waves like a modern submarine blowing its ballast tanks", a scene depicted on the posters of the subsequent film of the book. Although this was an "artistically stimulating" highlight of the film, made using a 55-foot (17 m) model of the Titanic, it would not have been physically possible. At the time of the book's writing, it was still believed that the Titanic sank in one piece.
