NUNAVUT, CANADA—Last month, underwater archaeologists from Parks Canada with the support of Royal Canadian Navy divers descended to the wreck site of HMS Erebus, lost nearly 170 years ago during Sir John Franklin’s expedition to find the Northwest Passage. The ship, discovered late last summer in remote Arctic waters, was covered with kelp. Over the course of the five-day project, the team removed the kelp from the well-preserved ship’s port side. “It’s tedious, but all of a sudden you have a shipwreck that looks like a wreck site,” senior underwater archaeologist Ryan Harris told CBC News. “We haven’t identified what caused it to sink. Maybe on the starboard side we’ll see some evidence of trauma,” he added. The divers found Franklin’s cabin, and they recovered a cannon, ceramic plates, and two brass buttons from the uniform of a non-commissioned officer of the Royal Marines. “Those are the artifacts that are probably the most personal,” Harris said.
