No ref's, but it seems unlikely - they could more easily have used EM 
techniques on the cables.

If they were over the repeaters though, those had relays, whose clicking 
could perhaps have been detected acoustically.

I find it curious that the Germans didn't cut the transatlantic cables 
though - they knew where they were. Perhaps they didn't want to cut off 
an intelligence source?

The British (and Germans) both cut most of the UK-continent cables, 
though I have heard the British left one from Ireland, as they were 
reading the traffic.
