Which publication serves as the weekly source for changes in charts or aids to navigation?

The Local Notice to Mariners is the correct publication that serves as the weekly source for reporting changes in navigational charts and aids to navigation. It is issued by the U.S. Coast Guard and provides mariners with important updates on buoy placements, lighthouse status, and other navigational information that can affect safe navigation.

This publication is crucial for vessel operators, as it helps them stay informed about any changes or updates that may impact their routes or safety at sea. Each issue includes specific details about alterations to navigational aids, changes in waterway conditions, and upcoming or completed projects that could influence navigation.

Other options, while related to navigation, serve different purposes. The Light List provides information specifically about the characteristics and locations of lights and buoys, rather than issuing week-to-week updates. The Chart Catalog contains a listing of available nautical charts but does not provide the ongoing updates that the Local Notice to Mariners does. The US Coast Pilot is a more comprehensive navigational guide providing descriptions of coastlines, harbors, and specific areas, but it is not released weekly and does not serve the immediate purpose of alerting mariners to changes.
