Coast Guard divers from Regional Dive Lockers East and West and U.S. Navy divers join in Operation Nanook, an exercise organized by the Canadian Coast Guard and the Canadian Maritime Command. The operation promotes international cooperation and strengthens the ability to respond to emergencies in the Arctic. The Royal Danish Navy also participated. In the exercise shown here, a diver 'bounce' dives 130 feet, trying to find sunken fuel barges. During a bounce dive, the diver descends directly to the maximum depth, spends very little time at that depth and ascends directly at a safe rate to the surface.
