The information in RAMN 2012 is grouped into five parts:

  2. Pacific Coast, Western Arctic (includes Athabasca-Mackenzie Watershed)
  3. Vessel Traffic Services

  5. Environment Canada

Part 1 provides mariners with advance information on proposed changes to facilities and services. It includes the Canadian Maritime Mobile Safety and Public Correspondence communication frequencies, a legend for centre listings and the telephone/facsimile/telex directory of MCTS centres along with the Regional offices' addresses.

Part 2 lists, in tabular form, detailed operational information about individual facilities in each of the areas covered. MCTS centres provide continuous year round communications and special services except as noted.

Part 3 provides consolidated information concerning Vessel Traffic Services.

Part 4 describes the various procedures, services and systems available, together with general observations or directions for their use.

The proper use of radio frequencies and procedures is essential to minimize congestion and delays on the channels available for communication.

Part 5 provides all relative information concerning Environment Canada's services in marine meteorology that are delivered by the Canadian Coast Guard.
