this involved, I think, just intuiting signals from the nearfield
effects of the cable, no? 'drop a large sensor ontop-of/next-to the
cable, win!'

this I thought included the capabilities to drag the fiber/line into
the hull for 'work' to be done... I'd note that introducing signal
loss on the longhaul fiber seems 'risky', you'd have to know (and this
isn't hard I bet) the tolerances of the link in question and have a
way to stay inside those tolerances and not introduce new
splice-points/junctions/etc and be careful for the undersea cable
power (electric) requirements as well.

fun stuff!

and yea, why not just work with the landindstation operators to use
the existing monitoring ports they use? (or get a copy of the monitor
ports)
