[edit] Water level?
I do not understand why the sea level must have been 3000m lower in former times in order to form submarine canyons. The deepest is 1km. Did the author mean 3000ft?
One other thing: "Canyons may have been carved by turbidity currents, or dense, sediment-laden currents triggered by earthquake which flow down the continental margin." sound definitely wrong. I changed this to "Canyons may have been carved by turbidity currents (dense, sediment-laden currents which flow down the continental margin, triggered e.g. by earthquakes)", because a turbidite current is just what the next words discribe. The meaning of "Submarine canyon" is an underwater canyon.

[edit] Date of Discovery
In a link to this section, "Continental Shelf" mentions that submarine canyons were only recently found out about.
Any mention of a date on this page would seem appropriate.
