The derelict Japanese fishing vessel RYOU-UN MARU drifts more than 125 miles from Forrester Island (near Dixon Entrance) in Southeast Alaska where it entered U.S. waters on Saturday (3-31-12). The fishing vessel has been drifting unmanned at sea since the 2011 Fukoshima earthquake and subsequent tsunami more than a year ago. The crew of a Coast Guard C-130 dropped a data buoy to help monitor the drift of the hulk. (U.S. Coast Guard photo by Air Station Kodiak)
