Automated
Notice to
Mariners
System
(ANTMS)
The ANTMS is used by the DMAHTC to process navigational data and
to produce the Notice to Mariners, the Summary of Corrections, the List
of Lights, and Sailing Directions. Your ship can query the ANTMS by
message to obtain the latest navigation information while you are at sea.
For example, this could be of great importance if you have not received
the most recent issues of Notice to Mariners and want to check for the
latest corrections to charts you will be using to enter your next port.
Instructions explaining how to gain access to the ANTMS may be
obtained by writing to the DMAHTC, Attention: NVS, and requesting a
copy of the Automated Notice to Mariners Communications Users
Manual.
Local Notice to
The Local Notice to Mariners is published weekly by the U.S. Coast
Mariners
Guard. It contains information of a local nature. As the U. S. Coast
Guard is responsible for maintaining all U.S. Aids to Navigation, they
report any changes that may have been made. This may include
information such as the movement of buoys and markers, and changes in
depth of the water due to dredging. It will also contain information on
bridge closings, harbor restrictions, and general information concerning
harbors and local coastal areas.
