The Station Main Frame is a free-floating balanced platform that is held in place by side anchors. It is designed for up to 20 meters of water level variation. It is constructed almost completely of type 316 stainless steel and will give years of service in fresh water.
Station flotation is provided by four large polystyrene floats (approximately 120 Kg of buoyancy) attached to the station cross arms just beneath the water surface. Two additional floats are attached to the central main mast. A large perforated disc is attached to the central mast about 3 meters below the surface and prevents the station from bobbing due to the surface waves.
The station supports the LDS instrumentation. The T-Chain hangs from one of the arms, metrology sensors are mounted at top, and the data logger is contained by a rectangular 'holster' just beneath the surface.
The station is weighted at the bottom so that it remains upright.
