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.
- Towed array / streamer
- Equipment towed a long way behind a vessel — sonar, a hydrophone cable, a sampling sled — invisible at the surface.
- Tow / towing
- A vessel towing another vessel, a barge or a structure — slow, hard to manoeuvre, and with a long line between.
- 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.
- CANCEL THIS MSG
- The warning's own expiry: a line telling the reader when the message cancels itself.
