What the archive shows
265 messages are recorded since 1997-07-03 for the Bristol 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 135 of 265 recorded messages (51%), 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.
