Question 413 Deck General

The correct answer is A) weekly by the 9th Coast Guard District. The Great Lakes Edition of the Notice to Mariners is published weekly by the 9th Coast Guard District, which is responsible for the U.S. Coast Guard operations in the Great Lakes region. This publication provides important updates and information to mariners navigating the Great Lakes. The other options are incorrect because the Army Corps of Engineers publishes a separate navigation publication for the Great Lakes, the Naval Oceanographic Office is not involved in the publication of the Great Lakes Notice to Mariners, and the Commandant of the U.S. Coast Guard does not directly publish this regional navigation notice.
