Maritime Administration Advisories

Maritime Administration Advisories rapidly disseminate information on maritime danger, safety, and government policy, and other time sensitive matters pertaining to U.S.-flag vessel operations. Maritime Administration Advisories are issued by the Office of Security to vessel masters, ship operators, and other U.S. maritime interests. Advisories are communicated via telex or other message formats, and published on the Maritime Administration’s web site and the National Imaging and Mapping Agency's Weekly Notice to Mariners.
