What the archive shows

87 messages are recorded since 1970-02-04 for the Gulf of St. Lawrence. The selection uses the IHO sea area; a message may describe an exercise, equipment outage or continuing operation as well as a hazard report.

Icebergs accounts for 60 of 87 recorded messages (69%), 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.
