In this photo provided by the U.S. Coast Guard, a plume of smoke rises from a derelict Japanese ship after it was hit by canon fire by a U.S. Coast Guard cutter on Thursday, April 5, 2012, in the Gulf of Alaska. The Coast Guard decided to sink the ship dislodged by last year's tsunami because it was a threat to maritime traffic and could have an environmental impact if it grounded.
