Navigation General · Publications & Corrections

Which publication is the primary source for correcting U.S. nautical charts to reflect changes in aids to navigation, channel depths, and new dangers?

Explanation

The weekly Notice to Mariners published jointly by NGA and NAVCEN contains chart corrections, changes to nautical publications, and new hazards affecting ocean and coastal waters. Local Notices to Mariners (issued by each USCG District) cover inland, coastal, and Great Lakes changes and are used to supplement NtMs for U.S. waters.
