Reading this warning

Survey operations
A research or survey vessel is mapping the seabed or water column, often while towing equipment.

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.
