Cables are mostly damaged by fishing in coastal areas (continental =

that protects them. So it is crucial that the cable be buried at least =
one meter and preferably two meters in coastal waters. The big fishing =
boats scrape sea floor - the ecological equivalent of surface or =
'strip' mining. These boats scrap the ocean floor and can hit the cables =
or even sever them. =20
And consequently, the cables themselves have thicker and more rugged =
cladding in the coastal waters. A thick armor in the deep sea is simply =
too expensive and makes it difficult to raise the cable out of the water =
and repair it. Too much 'tension' according to the sailors that operate =
the ships that lay and repair these systems.=20
