Notices to Mariners contain important navigational information such as chart updates, changes in buoyage, prior warning of activities such as dredging, exclusion zones, harbour closures and byelaws etc.
Local Notices to Mariners are often available online and many harbour authorities allow you to subscribe for email updates as and when a new notice is published.
Admiralty Leisure (the leisure division of UKHO) has an web-based Leisure Notices to Mariners service, which has been specifically produced for Admiralty Leisure charts and folios. This details every chart on its own page and gives weekly updates of new information. Chartlets, if required, are available to download.
Imray has a similar corrections service on their website.
The UKHO publishes Navigational Warnings for NAVAREA1 and the UK Coast on its website. Many of these warnings are of a temporary nature, but others may remain in force for several weeks and may be superseded by Notices to Mariners.
Glasson Dock/River Lune Notices to Mariners are available by email from the Lancaster Port Commission.
