What are Notices to Mariners (NtM)?
Notices to Mariners (NtM) are critical publications that offer maritime safety updates and essential information for safe navigation at sea. These notices include corrections to nautical charts, navigational warnings, and changes to aids to navigation. They are issued regularly by various countries to ensure mariners have the most current and accurate data for safe navigation.
Definition and Purpose of NtM
NtMs are official publications that alert mariners to important changes affecting nautical charts and navigational safety. Their primary purpose is to provide timely information about hydrography changes, newly discovered hazards, and updates to navigational aids. By keeping their nautical products current with the latest NtMs, mariners can maintain situational awareness and navigate safely.
Obligation of Coastal States to Provide NtM
International maritime law mandates that every coastal state chart its coastal waters and share this information through NtMs. This ensures that all vessels navigating in these waters have access to accurate and up-to-date navigational data.
The U.S. Navy Hydrographic Office has been issuing weekly NtMs since 1886. In the United States, the National Geospatial-Intelligence Agency (NGA), National Ocean Service (NOS), and U.S. Coast Guard collaborate to publish the weekly Notice to Mariners. The Canadian Coast Guard (CCG) releases its Notice to Mariners publication monthly.
The below table is an example of how & when NtM are issued:

Local Notice to Mariners (LNM)
Local Notice to Mariners (LNM) are shared by each Coast Guard district, offering information specific to their jurisdiction. These notices address a broad spectrum of topics, including alterations to aids to navigation, temporary and permanent modifications to waterways, and critical safety advisories.
Broadcast Notice to Mariners (BNM)
Broadcast Notice to Mariners (BNM) serve as urgent safety advisories broadcast by the Coast Guard via radio stations. They deliver immediate alerts regarding hazards to navigation, such as drifting debris, malfunctioning aids to navigation, or other urgent matters necessitating prompt action from mariners.
Special Notice to Mariners (SNM)
Special Notice to Mariners (SNM) encapsulate critical annual information for mariners operating within a particular region. These notices detail seasonal buoy modifications, special events influencing navigation, or other enduring alterations to the maritime environment.
Country | Publication Frequency | Content |
Finland | 3 times per month (10th, 20th, last day) | Nautical channels, aids to navigation, obstructions, winter navigation |
United Kingdom | Annually (NP 247(2)) | Updates on sailing directions and miscellaneous nautical publications |
Content of Notices to Mariners
Notices to Mariners (NtM) are vital for sharing critical marine navigation notices. They ensure the safety and efficiency of maritime operations. These notices cover a wide range of topics, from corrections to nautical charts and publications to navigational warnings and hazards.
One of the primary functions of NtM is to provide updates and corrections to nautical charts and publications. These documents are essential for safe navigation. It is crucial that they are kept up-to-date with the latest information. NtM inform mariners about changes in depths, obstructions, and other critical details that may affect their voyage planning and execution.
Navigational Warnings and Hazards
NtM also serve as a platform for issuing navigational warnings and alerts about potential hazards. These may include reports of floating debris, ice formations, or other obstacles that could pose a risk to vessels. By promptly sharing this information, NtM help mariners make informed decisions and take appropriate precautions to ensure their safety and that of their crew and cargo.
Changes to Aids to Navigation
Another critical aspect covered by NtM is changes to aids to navigation, such as lighthouses, buoys, and beacons. These aids play a vital role in guiding vessels safely through waterways. Any alterations or malfunctions must be promptly communicated to mariners. NtM provide details on the location, characteristics, and status of these aids, enabling mariners to navigate with confidence and precision.
Other Important Marine Information
In addition to the above, NtM also include a wealth of other important marine information. This may encompass details on naval operations, regattas, and other events that may affect vessel traffic in specific areas. NtM provide valuable insights into hydrographic surveys and channel depths. This empowers mariners to plan their routes effectively and avoid potential groundings or collisions.
Accessing and Staying Up-to-Date with NtM
Ensuring safe navigation on the seas necessitates the most current and precise marine navigation data. Notices to Mariners (NtM) deliver vital maritime navigation safety advisories and updates, imperative for all mariners. It is crucial to remain current with NtM to safeguard vessels, crew, and cargo.
Weekly Publications and Printable Versions
Maritime authorities publish Notices to Mariners on a weekly basis. These are accessible in printable formats, facilitating mariners' ability to access and reference the latest marine navigation updates. Weekly NtM publications encompass a broad spectrum of topics, including corrections to nautical charts, navigational warnings, and changes to aids to navigation.
Overview of NtM by Week and Chart
NtM publications often organize notices by week and chart, simplifying navigation and referencing. This structure enables mariners to swiftly identify pertinent marine navigation information for their specific operational areas. The overview typically summarizes key changes and updates, along with references to affected charts and publications.
Reporting Uncharted Dangers, Changes, or Errors
Mariners play a crucial role in maintaining maritime sector safety by notifying authorities of uncharted hazards, changes, or inaccuracies in nautical products. This collaborative effort guarantees the accuracy and completeness of nautical navigation alerts, promoting marine navigation safety information throughout the maritime domain.
Reports of shoal soundings, uncharted dangers, and issues with aids to navigation can be radioed to the nearest coast radio station. Even with incomplete information, reports should be made with as much detail as possible.
Accurate location details are essential when reporting. Latitude and Longitude should only be specified when obtained by GPS. Upon receiving Hydrographic Notes, the National Hydrographic Office sends an acknowledgment, using the sender's ship or name as authority for the reported data.
Organization | Responsibility |
U.S. Naval Oceanographic Office (NAVOCEANO) | Conducts hydrographic and oceanographic surveys of foreign or international waters |
National Oceanic and Atmospheric Administration (NOAA) | Provides charts for marine and air navigation in the coastal waters of the United States and its territories |
U.S. Coast Guard | Collects, analyzes, and shares navigational and oceanographic data, ensuring safety at sea and improving the marine environment |
Reports on ice concentrations, thickness, and position, as well as floating derelicts, wrecks, man-made obstructions, and shoals, are crucial. They ensure accurate charting and navigation safety. Discolored water sightings are also significant, indicating possible water pollution.
