What the archive shows

1,132 messages are recorded since 1999-01-03 for the Irish Sea and St. George's Channel. The selection uses the IHO sea area; a message may describe an exercise, equipment outage or continuing operation as well as a hazard report.

Nav aids accounts for 656 of 1,132 recorded messages (58%), the largest category group in this selection.

The NGA historical archive froze in 2024-05; live collection began 2026-08-17. Counts around that gap are incomplete, and changes in reporting volume do not establish changes in incident frequency.
