The RMS Titanic remains where she sank on April 15, 1912: 3,800 meters (12,500 ft) below the North Atlantic, 600 km south-southeast of Newfoundland. The bow and stern lie 600 m apart, surrounded by a debris field spanning 2 km².
5,500+ artifacts since 1987: personal effects, ship fittings, coal, a 17-ton hull section ("The Big Piece" displayed in Las Vegas). Expeditions (Woods Hole, IFREMER, RMS Titanic Inc., OceanGate) have mapped the site via ROV, photogrammetry, and sonar.
Bacteria (Halomonas titanicae) consume ~180 kg of iron daily. The bow may collapse within decades. The wreck is becoming an artificial reef—corals, anemones, rattail fish, crustaceans colonizing the steel. In situ preservation with 3D documentation is the emerging consensus.
