For 100 years, the great ship Titanic has rested in its final grave on the ocean floor. Now on the anniversary of its sinking, National Geographic offers this exclusive look at remarkable new imagery of the ship, the science of underwater mapping, and new findings linking artifacts to Titanic passengers. Did the Titanic actually just sink or was there something more dramatic to its final fated hours? National Geographic presents compelling analysis of the Titanic's likely path to the ocean floor, complete with an exclusive mosaic of seamlessly integrated sonar images showing for the first time ever in fine detail the complete debris field, 1 mile in diameter. In addition, never-before-seen clarity of debris field items such as the boilers come to life in these unprecedented images. New research linking artifacts with Titanic victims allows National Geographic to tell some of the personal stories of the items on tour. And the remains of the hulking ship fuel breakthroughs in the science of underwater decomposition.
