The first full-sized 3D scan of the Titanic shipwreck, released recently, could reveal more information about the ocean liner's fateful journey across the Atlantic more than a century ago. The high-resolution images, published by the BBC, use deep-sea mapping to reconstruct the wreck, which lies at a depth of nearly 4,000 metres (13,100 feet). Deep-sea mapping company Magellan Ltd and Atlantic Productions, which is producing a documentary about the project, completed the reconstruction in 2022. Submersibles controlled remotely from a specialist ship spent over 200 hours surveying the wreck at the bottom of the Atlantic, collecting over 700,000 images for the scan. Gerhard Seiffert, who led the expedition's planning, told the BBC that they were not allowed to touch anything "so as not to damage the wreck." "The other challenge is that you have to map every square centimetre – even uninteresting parts, like on the debris field you have to map mud, but you need this to fill in between all these interesting objects," Seiffert said. The images show the wreck – its stern and bow lying apart surrounded by debris – as if it were lifted from the water, revealing even the smallest details, like the serial number on one of the propellers. "Now we are finally getting to see Titanic without human interpretation, derived directly from evidence and data," Parks Stephenson, who has studied the Titanic for many years, told the BBC. Stephenson said there is "still much to learn" from the wreck, which is "essentially the last surviving eyewitness to the disaster".
