What the archive shows
121 messages are recorded since 1979-11-15 for the Sea of Marmara. The selection uses the IHO sea area; a message may describe an exercise, equipment outage or continuing operation as well as a hazard report.
Cable ops, Surveys tie for the largest recorded count, with 44 messages each.
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.
