🔍 Key Concepts

• NAVAREA (Navigational Area) system used for Maritime Safety Information (MSI) broadcasts under the IMO World-Wide Navigational Warning Service (WWNWS) • Geographic coverage of NAVAREAs in the Western North Atlantic and Eastern Pacific • Which NAVAREA numbers are assigned to areas around the continental United States, Alaska, Hawaii, and U.S. territories

💭 Think About

• Think about which ocean regions the continental U.S. borders and match those to the NAVAREA numbers that cover the Western North Atlantic and the Eastern Pacific. • Consider where Alaska and Hawaii are located and whether they fall in the same NAVAREAs as the Atlantic or Pacific coasts of the U.S., or in different ones. • Eliminate any NAVAREA pairs that are clearly associated with regions far from North America, such as the South Atlantic, Indian Ocean, or Southern Ocean.

✅ Before You Answer

• Verify which NAVAREA covers the Western North Atlantic, including the U.S. East and Gulf coasts. • Verify which NAVAREA covers the Eastern North Pacific, including the U.S. West Coast and Alaska. • Confirm that the NAVAREA pair you choose corresponds specifically to North American coastal waters, not South America, Europe, or Africa.
