NEW ORLEANS, La. (Oct. 6, 2006)--Coast Guard Petty Officer 3rd Class Luis Cabrera corrects a nautical chart Friday, Oct. 6, 2006, at Coast Guard Station New Orleans. Unlike roadmaps, nautical charts are often corrected because the position of objects, such as buoys, often changes with tides and currents. USCG photograph by Petty Officer 2nd Class NyxoLyno Cangemi
