An archive in Belfast is being used in an operation to clear an oil leak from a shipwreck half way across the world.
The MV Schiedyk lies an estimated 400 feet under water off the western coast of Vancouver in Canada.
It sank in January 1968 after hitting an underwater ledge.

More than 50 years later, an oil leak has been traced back to the wreck.
National Museums NI is helping the Canadian coastguard’s operation by supplying plans and images from the building of the 483ft cargo ship in Belfast in 1949.
