The wreck of the RMS 'Titanic' lies at a depth of about 12,500 feet (3.8 km; 2.37 mi), about 370 miles (600 km) south-southeast off the coast of Newfoundland. It lies in two main pieces about a third of a mile (600 m) apart. The bow is still recognisable with many preserved interiors, despite deterioration and damage sustained hitting the seafloor. In contrast, the stern is completely ruined. A debris field around the wreck contains hundreds of thousands of items spilled from the ship as she sank.

'Titanic' sank in 1912, when she collided with an iceberg during her maiden voyage. Numerous expeditions tried using sonar to map the sea bed in the hope of finding it but were unsuccessful. In 1985, the wreck was finally located by a joint French–American expedition led by Jean-Louis Michel and Robert Ballard of the Woods Hole Oceanographic Institution.

At 12.48 am on Sunday 1 September 1985 pieces of debris began to appear on the research vessel Knorr's screens. One of them was identified as a boiler, identical to those shown in pictures from 1911. The following day, the main part of the wreck was found and Argo (an unmanned deep-towed undersea video camera) sent back the first pictures of Titanic since her sinking 73 years before. The discovery made headlines around the world.
