Archaeologists working on Canada’s remote Sable Island say they may have uncovered the remains of a historic shipwreck that could date to before the 20th century. The discovery comes from the island long known as the “Graveyard of the Atlantic,” where hundreds of ships have been lost over centuries.
Sable Island lies about 185 miles (300 km) southeast of Halifax, Nova Scotia. Since 1583, more than 350 ships have been destroyed near the narrow sandbar. Many sank offshore, while others broke apart and were buried beneath the island’s shifting dunes. Researchers now believe one of those long-lost vessels has resurfaced beneath the sand.
Excavation reveals well-preserved remains
In May 2025, a team of underwater and terrestrial archaeologists began excavating the site on Sable Island’s North Beach. The project also included a Mi’kmaw archaeological technician working alongside Parks Canada researchers.
Over two weeks, the team carefully uncovered parts of the ship just below the sandy surface. Despite decades—or possibly centuries—beneath the dunes, researchers described the remains as “remarkably well preserved.”
Sable Island’s constantly shifting sands often bury shipwrecks for long periods before winds and storms expose them again.
“You can see broken up bits of shipwrecks that appear now and then as the sands reveal them inland on the island and also along the beaches,” said Rebecca Dunham, a terrestrial archaeologist with Parks Canada.
Artifacts provide clues to the ship’s identity
Determining the ship’s identity remains difficult. Much of the structure is damaged, and only fragments of the vessel have survived.
“It’s very difficult to have diagnostic or particular features visible on these wreck sections that can that you can say, ‘Hey, that’s potentially part of this wreck from this time period,’” Dunham said. Still, the excavation revealed several important clues.

Some wooden pieces and copper fragments carry the British Royal Navy broad arrow mark. The symbol was used to identify materials owned by the British government or navy. Archaeologists also identified parts made from Bermuda cedar, a wood commonly used in shipbuilding during the 18th and 19th centuries because of its durability.
These discoveries suggest the wreck could be connected to one of three historic ships lost near Sable Island: HMS Barbadoes, the naval sloop Swift, or the schooner Emeline.
Historical records point to an early 19th-century disaster
Historical documents describe the loss of HMS Barbadoes and three other ships that were traveling from Bermuda to Newfoundland in the early 1800s.
According to those records, one vessel from the group managed to reach Halifax and warn authorities about the disaster. Researchers believe the debris field uncovered on Sable Island may be connected to that event.
“The island is revealing to us through the exposure of particular artifacts and features that we can associate with wreck events,” Dunham said. “We’re relying on the island to reveal stories rather than seeking them out specifically.”
If confirmed, the discovery would be unusual. Archaeologists rarely manage to link a wreck on Sable Island to a clearly documented ship loss from before the 20th century.
A sandbar long feared by sailors
Sable Island stretches about 44 kilometers across the North Atlantic and is known today for its wild horses and protected ecosystem. But for centuries, sailors viewed it as one of the most dangerous places along major shipping routes.
Hidden sandbars extend far beyond the visible shoreline, creating a large underwater hazard. Storms, thick fog, and powerful currents often pushed ships toward the shallow sands.
“It’s the nature of the island,” Dunham said. “The island itself is not large, but the sandbars continue underwater for quite a distance to the north and south. So it’s like a massive obstacle in the ocean.”
Harsh conditions challenge modern researchers
Even today, the island’s environment can make archaeological work difficult. Strong winds frequently sweep across the dunes, sometimes blasting researchers with sand during fieldwork.
“Sometimes it can be a beautiful day, and other days the wind’s up, and it’s roaring out there, and you’re trying to do field work and getting sand blasted in the process,” Dunham said.
Despite these challenges, the excavation offered a rare opportunity for collaboration. Underwater and terrestrial archaeologists from Parks Canada were able to study the same wreck site together.
Researchers say further analysis of the materials and construction details will be needed before the ship’s identity can be confirmed. For now, the shifting sands of Sable Island continue to reveal another chapter in the region’s long maritime history.
