A team of scientists launched  an expedition to the Titanic on August 18th to assess the deteriorating condition of the world's most famous shipwreck and create a detailed three-dimensional map that will “virtually raise the Titanic” for the public. The expedition to the site four kilometres beneath the North Atlantic is billed as the most advanced scientific mission to the Titanic wreck since its discovery 25 years ago.

The 20-day expedition  left St. John's, Newfoundland on Aug. 18, in partnership with RMS Titanic Inc., which has exclusive salvage rights to the wreck, and the Woods Hole Oceanographic Institution in Massachusetts. The expedition will not collect artifacts but will probe a 3-by-5 kilometre debris field where hundreds of thousands of artifacts remain scattered. Only about 50% of the debris field has ever been examined.
Some of the world's most frequent visitors to the site are part of the expedition along with a who's who of underwater scientists and organizations such as the National Oceanic and Atmospheric Administration.
Organizers say the new scientific data and images will ultimately all be accessible to the public.
“For the first time, we're really going to treat it as an archaeological site with two things in mind,” David Gallo, an expedition leader and Woods Hole scientist said. “One is to preserve the legacy of the ship by enhancing the story of the Titanic itself. The second part is to really understand what the state of the ship is.”

Since oceanographer Robert Ballard and an international team discovered the Titanic in 1985, most of the expeditions have either been to photograph the wreck or gather thousands of artifacts, like fine china, shoes and ship fittings. “Titanic” director James Cameron has also led teams to the wreck to record the bow and the stern, which separated during the sinking and now lie one-third of a mile apart. RMS Titanic made the last expedition to the site in 2004. The company, a subsidiary of Premier Exhibitions Inc. of Atlanta, conducts traveling displays of the Titanic artifacts, which the company says have been viewed by tens of millions of people worldwide. 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.

Mr. Gallo said while the rate of Titanic's deterioration is not known, the expedition approaches the mission with a sense of urgency.
“We see places where it looks like the upper decks are getting thin, the walls are thin, the ceilings may be collapsing a bit,” he said. “We hear all these anecdotal things about the ship is rusting away, it's collapsing on itself. No one really knows.”
The expedition is using 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.
“We're actually treating it like a crime scene,” Mr. Gallo said. “We want to know what's out there in that debris field, what the stern and the bow are looking like.”
“Never before have we had the scientific and technological means to discover so much on an expedition to Titanic,” said P.H. Nargeolet, who is co-leading the expedition. He has made more than 30 dives to the wreck.

Bill Lange, a Woods Hole scientist who is  leading the optical survey and one of the first to visit the wreck, said a key analysis will be comparing images from the first expedition 25 years ago and new images to measure decay and erosion.
“We're going to see things we haven't seen before. That's a given,” he said. “The technology has really evolved in the last 25 years.”
“I'm sure there will be future expeditions because this is the just the beginning of a whole new era of these kind of expeditions to Titanic – serious, archaeological mapping expeditions,” said Mr. Gallo .
