A storage structure is configured to be buoyant or retained above a water line. The storage structure includes a frame having a back beam, a left beam attached to the back beam, a right beam attached to the back beam and a front beam attached to the left beam and the right beam to form a substantially rectangular configuration, wherein prior to a last of the beams being secured together an interior space accessible through an opening. The storage structure includes a bladder configured to be positioned through the interior space though the opening wherein the bladder is sized to be retained within the interior space whether the storage structure is above the water line or buoyant, the bladder including a vent, a fill port and a drain wherein an amount of water within the bladder is manipulated to provide ballast or buoyancy to the storage structure. The storage structure includes at least one floor panel secured to the frame over the bladder, side walls extending from a perimeter of the floor panel, wherein one side wall includes a door for ingress and egress to the storage structure. The storage structure includes a roof attached to the side walls.

A shallow-sea self-submerging/floating profiling buoy based on a flexible solar material, and a use method thereof. The buoy includes a detection unit. The detection unit includes a shell assembly, a sensing assembly arranged at the top of the shell assembly, a hydraulic system arranged inside the shell assembly, and a control assembly arranged inside the shell assembly. The hydraulic system includes an inner oil bag, an outer oil bag, a first two-position two-way electromagnetic directional valve connected to the inner oil bag through a pipeline, a second two-position two-way electromagnetic directional valve connected to the inner oil bag through a pipeline, a third two-position two-way electromagnetic directional valve connected to the first two-position two-way electromagnetic directional valve, and a fourth two-position two-way electromagnetic directional valve connected to the second two-position two-way electromagnetic directional valve.
