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.
Chart reference
The number of the nautical chart on which the reported position lies.
Scientific mooring
Instruments anchored to the seabed and held up by floats, sometimes just below the surface, left for months to measure the ocean.
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.
CANCEL THIS MSG
The warning's own expiry: a line telling the reader when the message cancels itself.
