The Worldwide Navigational Warning Service,

Abstract

In the early 1970's both the International Hydrographic Organization (IHO), an intergovernmental agency dedicated to the improvement of nautical charting, an the Intergovernmental Maritime Consultative Organization (IMCO), a U.S. agency dedicated to safety of life at sea, became concerned over the lack of a coordinated worldwide radio service to keep deep sea mariners aware of hazards to navigation. Through their joint efforts the Worldwide Navigational Warning Service (WWNWS) was established, becoming fully operational on 1 April 1980. The WWNWS covers all international shipping routes through a system of 16 NAVAREA Broadcasts, all of which transmit warnings in English (the primary language of the NAVAREA II broadcast is in French) and some of which transmit warnings also in an additional language. This paper describes the development of the initial WWNWS, the mechanism for service improvement and advances which have been made to date, and improvements foreseen for the future. Specific examples from the broadcast experience of the Coordinator for NAVAREA IV and XII and the Northwest Atlantic and Northeast Pacific NAVAREAs, respectively, are given. (Author)
