What the archive shows

260 messages are recorded since 1991-09-16 for the Arctic Ocean. The selection uses the IHO sea area; a message may describe an exercise, equipment outage or continuing operation as well as a hazard report.

Missiles accounts for 101 of 260 recorded messages (39%), 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.
