🔍 Key Concepts

• NAVAREA system used for navigational warnings (part of the Worldwide Navigational Warning Service) • Geographic coverage of western North Atlantic and Caribbean Sea on standard ocean basin maps • How NAVAREAs for the Pacific and Indian Oceans are numbered compared to those for the Atlantic

💭 Think About

• Look at which ocean basin the western North Atlantic and Caribbean Sea belong to and recall which NAVAREA numbers are assigned to that region. • Think about which NAVAREA numbers (X, XI, XII) are more often associated with areas in the Pacific or Indian Oceans, and which one is linked to the western Atlantic. • If you’ve seen a NAVTEX or NAVAREA warning example for the U.S. East Coast or Caribbean, what NAVAREA number was shown in that example?

✅ Before You Answer

• Confirm which NAVAREAs are typically associated with the Pacific Ocean and eliminate those choices. • Make sure the NAVAREA you choose actually covers both the western North Atlantic AND the Caribbean Sea, not just one or a different ocean. • Double-check that the remaining NAVAREA number you’re considering is operated/coordinated by a state bordering the U.S. East Coast / Caribbean region.
