Overview weekly editions

To support safe navigation, the Hydrographic Service publishes the most important changes to nautical products. It does so by issuing Notices to Mariners (NtMs). Besides browsing the NtMs Database, you can download all notices in a booklet (PDF). This booklet contains all notices of that particular week and is therefore also known as the weekly edition.

If you discover any uncharted dangers, changes, or errors in our products, please let us know by sending an e-mail to hydro.admin@mindef.nl.

As of week 15 (13 April 2023), The Netherlands Hydrographic Service will no longer issue tracings for Notices to Mariners.

Do you see uncharted dangers, changes or errors in nautical charts? E-mail to hydro.admin@mindef.nl.
