Reading this warning
- DNC (Digital Nautical Chart)

- Underwater operations
- Divers or remotely operated vehicles are working below a vessel that cannot easily move out of the way.
- Until further notice
- The operation or danger has no scheduled end; the warning stays in force until a later message cancels it.
- Position (degrees and minutes)
- How warnings write positions: degrees, a hyphen, then minutes, with N/S and E/W — 49-40.8N 003-43.8W.
- Wide berth requested
