What is a Bubble curtain?

A bubble curtain is a system that produces bubbles in a deliberate arrangement in water, commonly referred to as a pneumatic barrier. The technique involves releasing bubbles of air under the water surface, which rise to create a barrier that can break the propagation of waves or the spreading of particles and contaminants. It is used for several purposes, including reducing shock wave propagation, controlling the movements of fish, and providing decoration and airing in aquariums^[1].
