Three 40-foot cargo containers bound for Ketchikan went overboard in what was described as a weather-related mishap in British Columbia's Milbanke Sound.

Salvage operations are being conducted by Northland Services, the marine transportation company that operates the barge involved in the weekend incident.

Shawn Richardson, Northland's operations manager in southeast Alaska, says the tug Kirsten H was towing the barge Hunter Bay on a
regular run when the containers of "various cargo" went overboard. He says all the customers have been contacted.
