🔍 Key Concepts

• NAVTEX and marine safety information (MSI) responsibilities in U.S. waters • Which U.S. agency has primary responsibility for maritime safety broadcasts and SAR (search and rescue) • Difference between environmental science agencies and maritime safety / law-enforcement agencies

💭 Think About

• Ask yourself: Which of these organizations routinely issues marine safety information and urgent marine broadcasts on VHF and other marine radio systems? • Consider which agency operates rescue coordination centers and is in charge of keeping mariners informed about immediate navigational hazards. • Think about which agencies are more focused on weather and ocean data, and which are focused on operational safety and warnings to mariners.

✅ Before You Answer

• Verify which organization is responsible for marine safety broadcasts (MSIBs, safety calls on VHF, NAVTEX in U.S.). • Check which agency actually runs the maritime distress and safety communication system in U.S. coastal waters. • Confirm that the choice you pick is known for operational alerts to vessels, not just data collection, research, or port administration.
