What the archive shows
257 messages are recorded since 1997-03-09 for the Gulf of Aden. The selection uses the IHO sea area; a message may describe an exercise, equipment outage or continuing operation as well as a hazard report.

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.
