Which organization uses UMIBs to alert mariners?

Which organization uses UMIBs to alert mariners?

• A. Coast Guard (SMC)
• B. Navy
• C. Port Authority
• D. Fisheries Service

Answer: (A)

Urgent Maritime Information Broadcasts provide time-sensitive safety information to mariners under the GMDSS, designed for rapid dissemination of critical alerts in a specific area. In the United States, the Coast Guard operates the authority that issues these UMIBs to mariners, through its SMC. This role focuses on maritime safety and rapid alerting, which is why the Coast Guard is the organization that uses UMIBs to alert mariners. The Navy, Port Authority, and Fisheries Service have different primary missions (defense, local port operations, and fisheries management, respectively) and do not routinely issue UMIBs for mariner alerts.
