Reading this warning
- DNC (Digital Nautical Chart)
- A reference to one of the regions of NGA's Digital Nautical Chart, used to tell the reader which charts a warning affects.
- Semi-submerged
- Floating at or just below the surface, so hard to see by eye or radar.
- Adrift
- Loose and moving with wind and current — a vessel, container, buoy, log or anything else no longer secured.
- 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.
- Date-time group (DTG)
- A compact UTC timestamp — day, hour and minute followed by Z — such as 201500Z for the 20th at 15:00 UTC.
- CANCEL THIS MSG
- The warning's own expiry: a line telling the reader when the message cancels itself.
