Titanic Debris Site Mapped by Underwater Robots

Researchers have mapped the entire debris field of the doomed ship, RMS Titanic, using underwater robots and found new clues to learn what happened to the ship 100 years ago, when it hit an iceberg and sank killing more than 1,500 people.

A team of researchers have mapped the entire three-by-five-mile Titanic debris field using sonar imaging and more than 100,000 photos taken from underwater robots.

Explorers have earlier mapped the floor around the wreckage but those old maps were incomplete.

"With the sonar map, it's like suddenly the entire room lit up and you can go from room to room with a magnifying glass and document it," Parks Stephenson, a Titanic historian, was quoted as saying.

"Nothing like this has ever been done for the Titanic site," he added.

The team, which began mapping the debris in 2010, is now planning to air a two-hour documentary on the expedition on 15 April, 100 years after the Titanic sank.
