A 53-year-old man was evacuated from a freighter on Lake Superior by a U.S. Coast Guard helicopter on Thursday after a medical emergency.

The crew member aboard the James R. Barker, which left Two Harbors earlier this week with a load of iron ore pellets bound for Indiana Harbor, Ind., exhibited "symptoms of a medically urgent nature and was recommended by a U.S. Coast Guard flight surgeon to be evacuated to a trauma center," the Coast Guard reported in a news release.

The Barker was in Canadian waters of Lake Superior; Canadian officials requested support from the Coast Guard's air station in Traverse City, Mich. A Coast Guard MH-60 Jayhawk helicopter responded, hoisted the crewman from the freighter and transported him to Marathon, Ontario. From there, he was transported to a hospital in Sault Ste. Marie, Ontario.

The crewman was not identified; his condition was not available Thursday night.

Lt. Ted Borny, the Jayhawk pilot, noted that the Coast Guard works with its Canadian counterparts "on a regular basis for search and rescue, ice operations and numerous other missions across our shared maritime border."
