Description: This state-of-the-art underwater optic and acoustic test tank is designed to be a resource for local academic, government and industrial researchers and product developers.
The 90,000-gallon tank is designed for development and testing of underwater measurement concepts and devices. The tank is built half below floor level and half above. It is fully supported on vibration isolators, and noise level measurements indicate that, acoustically, the tank is at least two times quieter than sea state.
Six 3 x 4-foot optical ports, each consisting of a good quality, low-iron glass, are built around the tank walls several feet above the floor. The instrumentation suite, which is under computer control, includes a variety of acoustic and laser-signal sources and power amplifiers. The tank holds either fresh or salt water, which have very different optical properties.
The filter system consists of a sand filter, bag filters, and UV sterilizer, which provides excellent water quality without the use of biocides.
