Beneath the surface
Underwater structures are man-made constructions built beneath the water's surface or designed to operate while submerged.
The term covers a wide range: tunnels crossing beneath rivers or harbors, foundations for bridges and oil platforms, submarine bases, and artificial reefs.
In marine engineering and diving contexts, underwater structures often require specialized materials and techniques to withstand pressure, corrosion, and currents: The divers inspected the underwater structures supporting the pier.
