positioning data, navigation aid information, and vessel traffic information. POISE is one
mechanism for communication and coordination among local/regional and national
stakeholders regarding our Marine Transportation system.
APPLICABILITY AND SCOPE. POISE is a path to port related information that exists on the
World Wide Web (WWW). It contains pages of links and has no data of its own. The web
pages are organized into 45 geographic areas. Each web page is maintained at the Captain of
the Port in the locations shown in Enclosure (1).
Most data sources within POISE are located outside the US Coast Guard. POISE contains
links to services already available on the WWW ... like the Physical Oceanographic Real-
Time System (PORTS) operated by the National Oceanographic and Atmospheric
Administration (NOAA). POISE categorizes links and provides an index or overview of
on-line information available for the major waterways in the U.S. See Enclosure (4) for an
example of required and optional links.
Who might use POISE? Anyone. Typical users may be mariners, harbor pilots, voyage
planning & Coast Pilot-like users, port authorities, shipping agents etc. It is a free web
site that points users to other information links, some of which may require conditions of
entry (i.e., a credit card number or an account agreement with a commercial enterprise.)
Coast Guard units will also use POISE to improve outreach and customer satisfaction.
REQUESTS FOR CHANGES. Units and individuals may recommend changes by writing via
the chain of command to Commandant (G-MWV).
