Reading this warning

Seismic survey
A survey that maps the rock beneath the seabed with sound pulses from air guns, recorded on streamers kilometres long.
Until further notice
The operation or danger has no scheduled end; the warning stays in force until a later message cancels it.
Area bound by
Introduces a list of positions that are the corners of an area — the polygon the warning applies to.
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.
