Reading this warning

Underwater operations: Divers or remotely operated vehicles are working below a vessel that cannot easily move out of the way.
Track line joining: Introduces a route through a series of positions — a cable route, a tow's track or a survey line.
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.
CANCEL THIS MSG: The warning's own expiry: a line telling the reader when the message cancels itself.
