Parks Canada has confirmed that the shipwreck discovered in Terror Bay by the Arctic Research Foundation (ARF) is indeed the HMS Terror. The crew of the ARF’s research vessel Martin Bergmann notified the government agency of their find on September 11th. Parks Canada’s Underwater Archaeology Team arrived to explore the wreck on September 15th. With help from the Canadian Coast Guard and Environment and Climate Change Canada, the team surveyed the site with side-scan sonar and a multi-beam echosounder. Underwater archaeologists dove the wreck three times.
The dives took place during difficult weather conditions and through poor visibility. The wreck’s upper deck is heavily covered by silt and marine life. Nevertheless, the divers were able to observe a number of features that were typical or unique to 19th century British polar exploration ships and the wreck has a number of design specifications that were common to both HMS Erebus and HMS Terror, including three masts, iron bow sheathings and a double-wheeled helm. There are no wrecks other than HMS Erebus with these features in the region.
Comparing this solid archaeological data to an extensive research archive that includes ship plans of HMS Erebus and HMS Terror, Parks Canada’s Underwater Archaeology Team was able to confirm that the wreck is HMS Terror. The scans showed the well preserved wreck has and features matching the historic records for HMS Terror, including: the configuration of the bowsprit (the spar extending from the ship’s bow); placement of the ship’s helm; the boarding port; and deck scuppers (holes on the side of the ship to allow drainage) which differ from HMS Erebus.
The Parks Canada marine archaeologists found that the shipwreck is intact from stem to stern. No artifacts or human remains were spotted on board, but the visibility was so bad that doesn’t mean there aren’t any to be found. The thick layer of silt and marine life is obscuring anything on the deck. It’s also preserving it.
Next on the agenda is working with the Government of Nunavut and the Designated Inuit Organizations to protect the wreck site.
