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
Well, take a look at this map and tell me how many TransAtlantic landing
stations are within several kilometers of each other.
Look at how the TransAtlantic cables converge to landing points (except for
Hibernia).

Hi Martin,
Look more closely. I agree the red dots are repeaters. The yellow dots are
repairs. And the yellow dots are bunched, which what you would expect for
