Underwater archaeologists were the first people in nearly 170 years to lay eyes on the HMS Erebus, a British ship that sank during an ill-fated exploration of the Canadian Arctic. The ship was one of two that went missing during John Franklin's infamous expedition to find a Northwest Passage between the Atlantic and Pacific Oceans. The sunken vessel was discovered in September 2014 during a search led by Parks Canada. [Read full story about the HMS Erebus shipwreck

During a two-day investigation at the site of the wreck, divers took measurements and photographs of the ship. They also collected artifacts, including this bronze bell. Their findings proved that they were looking at the HMS Erebus, and not its sister ship, the HMS Terror. (Credit: Parks Canada)


When in use, the bell would have been struck every half hour, day and night, not only to mark the time, but also to signal the crew's changing shifts, according to Parks Canada. The bell stopped ringing some time in 1846, when Franklin's expedition became trapped in ice.

"The bell of HMS Erebus provides a tangible and compelling connection to the Franklin ships and is an important part of naval and Canadian history," Leona Aglukkaq, Canada's Minister of the Environment, said in a statement. "The recovery of this important artifact is the crowning achievement for an incredibly successful 2014 search campaign that has captivated Canadians and the entire world." (Credit: Parks Canada)
