Wreck of the RMS Titanic but have been consumed by other organisms. "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 of IFREMER and Robert Ballard of the Woods Hole Oceanographic Institution. The wreck has been the focus of intense interest and has been visited by numerous expeditions. Controversial salvage operations have recovered thousands of items, which have been conserved and put on public display.
Atlantic Ocean and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Equatorial Counter Current subdivides it into the North Atlantic Ocean and the South Atlantic Ocean at about 8°N. Scientific explorations of the Atlantic include the Challenger expedition, the German Meteor expedition, Columbia University's Lamont-Doherty Earth Observatory and the United States Navy Hydrographic Office. The oldest known mentions of an "Atlantic" sea come from Stesichorus around mid-sixth century BC (Sch. A. R. 1. 211): "Atlantikoi pelágei" (Greek: Ἀτλαντικῷ πελάγει; English: 'the Atlantic sea'; etym. 'Sea of Atlantis') and in "The Histories" of Herodotus
