Parks Canada has wrapped up this year's search for the twin ships of the Franklin Expedition with tonnes of new data, but no sign of the vessels Erebus and Terror.
The government's chief underwater archaeologist says the search team was able to cover 150 square kilometres of sea floor near O'Reilly Island in Queen Maud Gulf.
Ryan Harris says about the same amount of sea floor remains to be covered in the area, which is considered the final resting place for the ships of the doomed 19th-century expedition to the Northwest Passage.
Harris says there's one year left in Parks Canada's three-year project to find the ships, but he's confident they will be found.
Earlier this summer, the same team found the wreck of the HMS Investigator, one of the ships sent out to find Franklin, in shallow water on the west end of the passage.
