Derelict ship reaches Alaska waters

Questions over what to do with a derelict Japanese shrimping vessel floating in the Gulf of Alaska are circulating around several governmental agencies.

The ship is a remnant of last year's Japanese earthquake and subsequent tsunami.

The Coast Guard's main concerns with the ship are potential maritime traffic problems, as well as its environmental impact.

US Senators Mike Begich and Maria Cantwell are also worried about the vessel's impact.

They say that research needs to be done in order to better understand possible impacts from debris from the quake.

The ship is currently headed towards Sitka at a rate of about one mile per hour, but Coast Guard officials say there is no immediate concern.
