The National Oceanic and Atmospheric Administration (NOAA) has
launched an electronic chart update service via its Nautical Charts Internet site. Users may access chart
updates published in the USCG Local Notice to Mariners, NIMA Notice to
Mariners, and Canadian Coast Guard Notice
to Mariners. Chart updates
include information on aids to navigation changes, hazards to
navigation, and other essential information for safe navigation.
