🔍 Key Concepts

• Aids to Navigation (ATON) responsibilities in U.S. waters • Which agency creates charts and sailing directions (NOAA) versus which maintains lights and buoys (USCG) • The purpose and typical contents of the Light List compared to other publications

💭 Think About

• Think about which publication is most directly tied to the operation and maintenance of lights, buoys, and other navigation aids • Ask yourself which agency (NOAA or USCG) is known for surveying and charting versus operating navigational aids and enforcing regulations • Match each option with the agency you associate it with: Which ones are more like "charting and reference books" and which one is more like an operational list of aids?

✅ Before You Answer

• For each choice, decide: Is this mainly about mapped geographic information (surveys, coast descriptions, water depths) or about specific navigation aids and their characteristics? • Verify which agency is primarily responsible for creating nautical charts and coastal sailing directions (hint: not the Coast Guard) • Identify which option sounds like a publication that would list lights, buoys, and beacons with details like color, period, and range—that is the one most logically tied to the U.S. Coast Guard
