Original warning text
KARA SEA. RUSSIA. DNC 22. BOTTOM SCIENTIFIC MOORING ESTABLISHED UNTIL FURTHER NOTICE IN 72-24.14N 074-20.55E. 200 METER BERTH REQUESTED.
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.
