Maritime Safety Information (MSI)

Chair, WWNWS: Christopher G. Janus  (U.S.A. - NAVAREA IV and XII Coordinator)


The United States (U.S.) is the NAVAREA IV and XII Coordinator and Brazil is the NAVAREA V Coordinator under the IMO/IHO World-Wide Navigational Warning Service (WWNWS), which means the internationally and nationally coordinated service for the promulgation of navigational warnings. As a NAVAREA Coordinator, the U.S. and Brazil have the responsibility for promulgating Maritime Safety Information (MSI) in the form of navigational warnings, from the coastal countries within the NAVAREA. Such information includes the following: failure and/or changes to major navigational aids, newly discovered wrecks or natural hazards including icebergs in or near main shipping lanes, hazardous military operations and areas where search and rescue, anti-pollution operations and cable-laying or other underwater activities are taking place. NAVAREA IV, V, and XII are staffed 24 hours per day, 365 days per year.
