🔍 Key Concepts

• Light Lists and what information they contain • Difference between aids to navigation (buoys, lights, daybeacons) vs. charting and surveying responsibilities • Roles of NOAA/National Ocean Service vs. U.S. Coast Guard

💭 Think About

• Ask yourself: Which agency is primarily responsible for maintaining and publishing information about operational aids to navigation, such as buoys and lights, for mariners? • Think about which agency runs or oversees the physical aids to navigation system on U.S. waters, not just mapping or scientific study of the oceans. • Consider which organization issues Notices to Mariners and updates about changes to lights and buoys.

✅ Before You Answer

• Verify which agency is directly in charge of aids to navigation in U.S. waters. • Confirm which organization produces Light Lists, while another produces Nautical Charts and Coast Pilots. • Make sure you distinguish between hydrographic/nautical charting duties and operational navigation aid duties.
