A detailed digital model of the sinking of the Titanic shows that the “unsinkable” ship was almost certainly destroyed after it struck an iceberg 113 years ago. Based on more than 715,000 underwater images, as well as a full-size three-dimensional movie model made for a new film, Titanic: the Digital Resurrection. The computer simulation in new research reveals insights into one of the deadliest maritime tragedies in history.

Titanic’s Digital Twin Reveals Violent Breakup and Heroic Crew Actions in Historic Detail

As per the statement from National Geographic, the documentary leverages advanced underwater scanning technology used by deep-sea mapping firm Magellan. Working alongside Atlantic Productions, the team spent three weeks capturing sonar data to produce the most precise digital model of the Titanic to date, accurate down to the rivet. The wreck is still sitting 12,467 feet below the surface of the Atlantic Ocean, where it settled after striking an iceberg four days into its inaugural journey from Southampton to New York.

With the digital reconstruction, researchers have been able to analyse the ship’s hull in new ways, revealing that it burst under pressure, rather than breaking cleanly in half. The team also found a steam valve in the hull that had been left open, which supports eyewitness reports that the engineers had continued to work to the end to keep power flowing and distress signals broadcasting. These selfless acts likely saved many lives, the documentary suggests.

Personal items such as pocket watches and purses were digitally catalogued and linked to their owners, lending a deeply human touch to the cold wreckage. A shark tooth charm was among the more unique finds. They found no trace of the fictional “Heart of the Ocean” necklace from James Cameron’s 1997 film, contrary to popular culture myths.

On April 11, 2022—the 113th anniversary of the ship’s fateful voyage—the documentary Titanic: The Digital Resurrection changed the narrative of one of mankind’s most notorious maritime disasters by combining wrenching memories with modern technology.
