A computer generated image of the Titanic wreckage
For almost three-quarters of a century its location at the bottom of the ocean was a maritime mystery.
Even when explorers found the wreck of the Titanic in 1985, they struggled to understand exactly what happened on that terrible night she sank.
Now researchers have come up with the clearest picture yet of the huge debris field at the bottom of the North Atlantic.
They used two robot vehicles to scan the ocean bottom day and night with sonar cameras, moving at 3mph back and forth in a grid pattern.
They then stitched together the 130,000 high-resolution photos on a computer to provide a detailed mosaic of the wreck.
The American team hope the results will provide clues about how the superliner broke apart after hitting an iceberg, killing more than 1,500 people on its maiden voyage.
New detail: Researchers have pieced together what is believed to be the first comprehensive map of the entire 3-by-5-mile Titanic debris field. This image shows the main body of the vessel
Mapping: This image shows debris surrounding the stern of the Titanic on the bottom of the North Atlantic Ocean. An expedition team used sonar imaging and more than 100,000 photos taken from underwater robots to create the map
Extraordinary: The large bow and stern sections which rest about half a mile apart from each other can be seen here. They separated when the ship split apart as it began to sink
