Reading this warning

Dredging: A dredger is deepening a channel or moving sediment, often with floating or submerged pipelines to the shore.
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.
