What Does the New Digital Scan Reveal About the Titanic’s Final Moments?

Few events have captured the public imagination as enduringly as the tragedy of the RMS Titanic. The supposedly unsinkable ocean liner sank after striking an iceberg during its maiden voyage from Southampton, England, on the night of April 14, 1912, claiming over 1,500 lives.

The wreck was discovered by Robert Ballard and Jean-Louis Michel in 1985 and has been extensively studied ever since, with numerous expeditions bringing both researchers and tourists down to the bottom of the North Atlantic.

Yet each of those expeditions, though undoubtedly awe-inspiring, has been limited by the obvious constraints of being 12,500 feet (3,800 m) below the ocean’s surface, in near-total darkness. Some submersibles have inadvertently damaged the fragile wreck, and the deep-sea expeditions themselves are inherently dangerous, as underlined by the recent tragedy of OceanGate’s Titan submersible, which imploded in June 2023. The Titanic itself is gradually disappearing due to the inexorable forces of time and marine microbes.

In 2022, however, a full-sized digital scan of the Titanic was completed by the deep-sea mapping company Magellan Ltd. The project was also spearheaded by Atlantic Productions, which is releasing a documentary about the effort, entitled Titanic: Digital Resurrection, on National Geographic this Friday.

To create the digital rendering, a pair of robotic submersibles spent over 200 hours surveying the wreckage, capturing over 700,000 photos and millions of laser measurements. It’s the largest underwater scan ever undertaken, totaling 16 terabytes of data.

The digital scan provides a detailed 3D view of the entire ship, from the upright bow to the mangled stern, which is located around 2,600 feet (800 m) away. The entire area is surrounded by debris from the ship and personal items belonging to the passengers, which were also captured in the scan.

Secrets from the ocean floor:

  • Although the Titanic’s “digital twin” hasn't been made available to the public yet, researchers have viewed the life-size projection and were able to zoom in and out. This level of detail has already provided compelling evidence about what happened in the Titanic's final hours - and even minutes.

  • For example, the scan has revealed an open steam valve and several concave boilers in the boiler room, suggesting that they were still operating as the ship sank. This corroborates survivor accounts that the lights stayed on until the moment the Titanic sank beneath the waves. The heroic effort by the ship’s engineers to keep shoveling coal into the furnaces likely saved many lives by providing enough visibility to launch the lifeboats while continuing to send out distress signals.

  • Digital twinning is a major breakthrough for archaeologists, scientists, and historians, who have used the technology to preserve significant and often vulnerable works of art, architecture, and even entire cities, from Michelangelo’s David to Pompeii to St. George’s Cathedral in Lviv, Ukraine.
