🔍 Key Concepts
• NAVAREAs (Navigational Areas) and how they divide the world’s oceans for Maritime Safety Information (MSI) broadcasts
• The role of U.S. Coast Guard Communications Area Master Stations (CAMS) such as NMF, NMC, NMO, NOJ
• Which U.S. coast corresponds geographically to NAVAREA IV
💭 Think About
• First, identify the geographic limits of NAVAREA IV. Which ocean area and which coast of the U.S. does it cover?
• Next, match each callsign (NOJ, NMF, NMC, NMO) to its primary location and ocean region (e.g., Alaska, Pacific, Atlantic, etc.).
• Then, decide which station’s normal coverage area lines up with the NAVAREA IV region you identified.
✅ Before You Answer
• Confirm the geographic boundaries of NAVAREA IV on an official NAVAREA/MSI chart or list.
• Verify the home location and coverage of each listed USCG station (Kodiak, Boston, San Francisco, Honolulu).
• Make sure the station you choose actually serves the Atlantic vs. Pacific vs. Alaskan region that matches NAVAREA IV.
