Greenpeace activists display placards inside the Department of the interior. The boards call attention to the series of disasters around Shell's 2012 Arctic Drilling program while Secretary of the Interior Ken Salazar addressed the opening of a Ocean Energy Safety Advisory Committee meeting. The protest follows Shell's Kulluk drilling rig breaking from a tow and running aground near Kodiak Island, Alaska on Dec. 29 and reports that the United States Coast Guard is conducting a criminal investigation of safety issues with Shell's Noble Discoverer rig currently in Seward.
