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.
Mines and mine danger areas: Sea mines reported adrift or found, and areas where mines are known or suspected to remain.
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.
