The wrecks of the last ships of famed explorers Sir Ernest Shackleton and Capt. Robert Falcon Scott have been replicated using 3-D imagery in minute detail, creating “digital twins” to preserve them for posterity.
asserted
wrecks → replicate → posterity
The 3-D digital replicas, created by knitting together tens of thousands of images captured on the ocean floor during an expedition this summer, are to be unveiled Wednesday at the Royal Canadian Geographical Society’s Ottawa headquarters for viewing by the public.
asserted
replicas → create → public
And the replicas will later be made available to schools across the country.

In 2024, the RCGS discovered the wreck of Sir Ernest Shackleton’s last ship, Quest – on which the renowned polar explorer died suddenly during an Antarctic voyage in 1922 – at a depth of 390 metres, off the coast of Newfoundland and Labrador.
asserted
explorer → discover → Newfoundland
This summer, an international expedition led by the RCGS went back to view the wreck up close in the Labrador Sea and, using a remotely operated vehicle, captured the first clear images of the sunken vessel.
asserted
expedition → lead → vessel
A three-man team – including RCGS chief executive John Geiger – became the first to directly set eyes on the historic wreck through the portholes of a submersible.
asserted
team → include → submersible
(The mini-submarine they used was the same one that in 1986 captured the first pictures of the Titanic, which sank off the coast of Newfoundland in 1912.)
asserted
which → use → 1912
The Canadian-led RCGS expedition then set sail to waters off Greenland’s coast to survey Terra Nova, the last vessel of famed Antarctic explorer Capt. Scott, who perished with his entire team while returning from a much-vaunted expedition to the South Pole in 1912.
asserted
who → lead → 1912
During the Second World War, Terra Nova was chartered to carry supplies to Greenland.
asserted
Nova → charter → Greenland
The ship, built in Dundee, Scotland, and launched in 1884, was damaged in 1943 while at sea and was deliberately sunk after the crew were rescued.
asserted
crew → build → sea
Digital twins of both wrecks, as well as models being made of them, will preserve them for posterity, Mr. Geiger said.

Geiger → make → posterity
The expedition used photogrammetric technology from Voyis Imaging, a company based in Waterloo, Ont., to capture detailed portraits of both ships.
asserted
expedition → use → ships
Tens of thousands of high-resolution images of the shipwrecks have now been knitted together “into a complete lucid picture” of both vessels, he said.
asserted
he → knit → vessels
The RCGS has also made a film of the expedition and a gallery of still photographs, including underwater images of the wrecks, for the exhibition.

RCGS → make → exhibition
“These wrecks are going to eventually disappear – they’re deteriorating, and there will come a point where they won’t exist at all,” Mr. Geiger said.
asserted
Geiger → go → ?
“They’ll just have been subsumed into the seabed.
asserted
They → subsume → seabed
And so what we’ve been able to do is capture – almost as if in amber – this moment, what these ships are like today.”
The RCGS-led expedition, which included the non-profit Massachusetts-based Woods Hole Oceanographic Institution, found that Quest had suffered considerable damage when she sank.
asserted
she → do → damage
Her masts were down, her nameplate – which dated back to Shackleton’s last expedition – was lost and the vessel was covered in sea life and abandoned fishing nets.
asserted
vessel → date → life
After the explorer’s death aboard the ship, it was used in several daring adventures, including helping to rescue a Danish crew marooned on ice floes off the coast of Greenland, Mr. Geiger said, speaking from London last week, where he was launching a book he wrote about Shackleton.
asserted
he → use → Shackleton
According to Mr. Geiger’s book, Quest, Shackleton’s Last Ship and the End of the Heroic Age, the vessel was chosen in 1930 by 23-year-old British Arctic explorer Gino Watkins to investigate the feasibility of an air route linking London with Winnipeg, via several hops from Scotland to the Faroe Islands, Iceland, Greenland and to Baffin Island.
uncertain
vessel → accord → Island
After its career as an exploration vessel ended, Quest returned to its original vocation as a sealing ship.
asserted
Quest → end → ship
It sank off the coast of Labrador after suffering damage in 1962.
asserted
It → sink → 1962
Mr. Geiger said Terra Nova, found in waters at a depth of 179 metres, off the coast of Greenland, was “a much more beautiful ship than Quest, which was a small, kind of stubby little workman-like vessel.”
asserted
which → say → Quest
The Terra Nova wreck was also better preserved than Quest, and the expedition discovered navigation equipment used during Capt. Scott’s ill-fated expedition to the Antarctic.
asserted
expedition → preserve → Antarctic
Although Terra Nova’s hull had split in two, its original rudder, propeller, two masts, as well as its wheel and ceramic mugs abandoned by its crew when she sank in 1943, were visible.
asserted
she → split → 1943
Mr. Geiger said “the imagery is absolutely striking” and will be closely studied, including to gain more insight into the sea creatures that have made them their homes.
asserted
them → say → creatures
He said the 3-D images are “extremely powerful” and make the viewer “feel like you’re basically swimming over the wrecks.”
asserted
you → say → wrecks
