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.
- Scientific mooring
- Instruments anchored to the seabed and held up by floats, sometimes just below the surface, left for months to measure the ocean.
- 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
- Keep well clear — or, when a distance is given ("TWO MILE BERTH REQUESTED"), at least that far away.
- Cancellation reference
- A line that cancels an earlier warning by its number, such as CANCEL HYDROLANT 1085/12.
- HYDROARC
- The U.S. long-range warning series for the Arctic Ocean.
