Titanic Presentation Notes * Process Used to Find the Titanic: (Bobby) * Discovered by Robert Ballard on September 1st, 1985 * Logbook of the Californian enabled Ballard to estimate the speed and direction of drift of the lifeboats. * The Californian was between five to ten miles away from the Titanic at the time of the disaster and reported in its log that they had experienced drift * Also Ballard knew that the Titanic had to be north of where the lifeboats were found * Titanic stemmed from a secret United States Navy investigation of two wrecked nuclear submarines * For 6 days, the Argo searched the sea floor and nothing came up. However, on the last day the team discovered a boiler * How the Titanic Sank: (Gary) * When a ship it sinks it leaves a path of debris (objects from within the ship or objects breaking off). Depending how deep the vessel sinks this debris can be scattered over a large distance. On a shorter descent, the debris falls more or less vertically. However, as the Titanic sank 21/2 miles a huge debris field was expected. A new search strategy was formed. This time they would first look for the debris field rather than the Titanic herself. * Things Learned From Wreckage: (Gary) * The ship did not have a large gash as previously thought, but actually a series of punctures * It was confirmed that the ship split into two while going down * Technology Used to Find the Ship: (Jordan) * The Argo, used by Robert Ballard, was an unmanned deep-towed sled that carried light-sensitive video equipment * Capable of reaching 6,000 meters * ROV Jason was launched in 1988 * Had better imaging and maneuvering * Tested fiber-optic cables in deep sea * Artifacts Retrieved: (Nick) * Many things were recovered; things like furniture
