Original warning text
WESTERN SOUTH ATLANTIC. URUGUAY. SEISMIC SURVEY IN PROGRESS UNTIL FURTHER NOTICE BY M/V WESTERN REGENT TOWING TEN 8800 METER LONG CABLES ALONG TRACKLINE BETWEEN 35-25.87S 055-05.80W AND 35-27.57S 055-11.92W. EIGHT MILE BERTH REQUESTED.
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.
- 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.
- 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.
