On August 18th, an expedition team will be heading out to the Titanic site to create a 3D map of the wreckage 2.5 miles beneath the sea. 1,522 people died in the Titanic shipwreck in 1912; oceanographer Robert Ballard discovered the remains in 1985, and since then a bunch of different expeditions have headed out there in an attempt to salvage artifacts or take photos. But this one appears to be by far the most technologically intensive and expensive mission.
The "dream team" of archaeologists, oceanographers and other scientists want to get the best assessment yet on the two main sections of the ship, which have been subjected to fierce deep-ocean currents, salt water and intense pressure.
…The expedition will use imaging technology and sonar devices that never have been used before on the Titanic wreck and to probe nearly a century of sediment in the debris field to seek a full inventory of the ship's artifacts.
