Shipwrecks of Shackleton and Scott recreated in 3D digital form after deep sea expedition

Canadian scientists visit remains of polar exploration vessels Shipwrecks of Shackleton and Scott recreated in 3D digital form after deep sea expedition Canadian scientists visit remains of polar exploration vessels in ‘golden era for shipwreck investigating’ Moments after devouring the final glimmers of light, the seafloor offered nothing but darkness and silt. Then the bow appeared. More than 1,000ft (305 metres) below the surface of the Labrador Sea, off the coast of Canada, the skeleton of the final ship used by the famed polar explorer Ernest Shackleton appeared in its silty grave. “To see a very large ship in the abyss, and to realise you are among the first humans to see it, and to realise that it is largely intact is a powerful experience,” said John Geiger, the head of the Royal Canadian Geographical Society (RCGS). “It moves you.” Days later, Geiger was again inside the Alvin, the first submersible to take people to the Titanic shipwreck four decades prior, staring at the remains of the Terra Nova – the ship used by Robert Falcon Scott on his ill-fated Antarctic expedition.

Geiger, the expedition leader, said the project represented a “golden era for shipwreck hunting and investigating” as technological leaps allowed researchers to better map and model the final resting sites of the famed ships. The 21-day expedition left Woods Hole Oceanographic Institution in Massachusetts on 2 July and for two weeks has been attempting to digitally preserve the final ships of Britain’s most acclaimed polar explorers.

Photograph: Martin Hartley/Canadian Geographic Shackleton was among the titans of an era historians often refer to as the “heroic age” of Antarctic exploration, one defined by obsession and hubris. His 1914 exploration trip to the Antarctic region on the Endurance ended after his ship was trapped in the ice and eventually crushed. The crew survived on ice floes, then made their way to Elephant Island, off the east coast of Antarctica. Over repeated trips that took months, Shackleton ensured his entire team survived. In 1922, at 47, he died of a heart attack while on Quest, the ship he had outfitted to explore Canada’s high Arctic. The Quest later sank in 1962 and wasn’t discovered until 2024, in an expedition also led by Geiger. The Terra Nova, a wooden-hulled three-masted ship, carried Scott and his crew in their 1910 bid to be the first people to reach the south pole. Scott reached it on 17 January 1912, only to learn that the Norwegian explorer Roald Amundsen had beaten him by a month. Scott and all four members of his south polar party died on the return journey. The Terra Nova carried news of their deaths to the world and was later used in the Newfoundland seal fishery before sinking in 1943. The RCGS team used underwater imaging technology developed by the Canadian company Voyis to build detailed, three-dimensional models of the wrecks, in the knowledge that the Terra Nova and the Quest will one day be fully reclaimed by the ocean.

We’re seeing these ships magically appear through this process in front of us on the screen,” said Geiger. “It’s just mind-boggling.” While Shackleton suffered his heart attack on the Quest, neither ship experienced casualties prior to sinking – meaning there were no large, unsolved mysteries surrounding their fates. Instead, for this expedition, Geiger said the aim was to inspire a new generation of explorers. “There’s so little of the ocean that’s mapped,” he said. “The territorial waters of Canada are largely unmapped in the Arctic. There’s so little we know and I’m staggered at the ignorance we have about the oceans and about ocean life.” Recent advances in submersible technology promise to reveal new frontiers in exploration. Five years ago, the Alvin was approved to extend the depths it could safely explore, from 14,700ft to 21,300ft.

If there wasn’t a titanium hull and a lot of sea water [between the Alvin and the wreck], you feel like you could just reach out and touch it.” View image in fullscreen Five years ago, the Alvin submersible was approved to extend the depths it could safely explore to 21,300ft. Photograph: Martin Hartley/Canadian Geographic Geiger said although the expedition relied on the tools of modern explorers, it was driven by the age-old human experience of pushing towards the unknown. “Future expeditions will surely use robots and automated vehicles. But I don’t think we can ever abandon, when possible, the human role in exploration. Because what is lost is poetry, romance and wonder. Those are not the characteristics of machines. They are the uniquely human threads that connect us to the past – and what push us forward.” Explore more on these topics Science Canada Americas Marine life Exploration Oceans news Share Reuse this content
