What the archive shows

1 messages are recorded since 2023-09-06 for the Gulf of Bothnia. The selection uses the IHO sea area; a message may describe an exercise, equipment outage or continuing operation as well as a hazard report.

1 recorded messages form a small sample; the category breakdown should be read as individual records rather than a pattern.

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.
