A full-scale digital scan of the Titanic has provided unprecedented insight into the final hours of the doomed vessel, revealing structural details, crew efforts, and iceberg damage that had previously gone unseen.
The 3D "digital twin" was created from over 700,000 high-resolution images captured by underwater robots at a depth of 3,800 metres in the North Atlantic.
It offers a complete, panoramic view of the shipwreck for the first time, allowing researchers to study the disaster site in forensic detail.
The bow section of the liner lies upright on the seabed, while the stern, located 600 metres away, is a tangled mass of metal—evidence of the extreme forces unleashed as the ship broke apart and sank in 1912, killing over 1,500 people.
"This is like a crime scene, and the full scan lets us understand what really happened," said Titanic analyst Parks Stephenson.
The scan also uncovered critical clues, including a smashed porthole likely caused by the iceberg, a boiler room near the ship's break point, and an open steam valve on the stern—suggesting engineers kept power flowing until the last moment.
'These men held chaos at bay, allowing lifeboats to be launched in light, not darkness,' said Stephenson.
A computer simulation based on the ship's blueprints and navigation data shows that the iceberg caused a series of narrow hull punctures, each only the size of an A4 sheet of paper, but collectively spread across six watertight compartments—more than Titanic could withstand.
'The difference between survival and sinking was razor thin,' said Simon Benson, naval architecture expert at the University of Newcastle.
Though parts of the hull remain buried in silt, the scan continues to offer new information. Personal belongings can also be seen scattered on the ocean floor, bringing the human tragedy into sharper focus.
The data was collected for a National Geographic documentary, Titanic: The Digital Resurrection, produced with Atlantic Productions and Magellan. Experts say the scan may take years to fully analyse.
'She still has stories to tell,' Stephenson said. 'And each time, she leaves us wanting more.'
