Ouessant Bell Marine
Author 'Charly' (Id 222595
) : Face the lighthouse of the Créac'h a bell underwater has been built on the coast in 1912. By time of fog, a bell electrified was submerged and operated from the lighthouse. The sound waves transmitted under water were received from surrounding ships equipped with hydrophones. The captured sounds were intended to situate himself in relation to the island. The system, quickly dethroned by the arrival of the radio, will be dismantled in 1919.
Of this system, it remains only a piece of building support arm supporting the bell (to the left in the photo).
