How the Moon Impacts Subsea Communication Cables: Poisson effect on pressurized cables | HackerNoon
Briefly

The Poisson effect in pressurized cables leads to an increase in cable length during high tide, which correlates positively with the measured phase delay (MPD).
By evaluating the Young modulus and Poisson ratio under static pressure, we estimate a ~4.5 cm length change for the cable during high tide, indicating its substantial effect on MPD.
