Fundamental to any underseas program is the platform used to carry the investigator beneath the sea. The fixed habitat offers long-term, continuous, in-situ observation and experimentation. Simmilar to a lockout submersible, it can deploy the best manipulation system to date: the human being. The saturation diving habitat, HYDROLAB, constructed in 1966 by Perry served as a shallow water underwater laboratory for science missions for fifteen years, beginning in 1970. The HYDROLAB was a cylindrical chamber 16 feet long by 8 feet in diameter, equipped with spartan accommodations, yet unmatched in its day in scientific support efficiency. Funded by the Perry Foundation and NOAA, the HYDROLAB was the basis of MUS&T’s coral reef research program. In 1978, with the reorganization of the Diving Program, the habitat operations began being conducted through the NOAA Undersea Research Program. From 1977-85, HYDROLAB, situated in Salt River Canyon, St. Croix, U.S. Virgin Islands, hosted over 120 scientific groups, 352 aquanauts totaling 11,251 excursion man-hours of safe diving to depths of 150 feet during 55,056 total saturation hours. The 85 scientific missions produced a 90% publication per mission productivity level. The habitat was decommissioned in 1985 and placed on display at the Smithsonian Institution’s National History Museum in Washington, D.C. The HYDROLAB legacy was maintained with the arrival of the undersea habitat AQUARIUS in 1987. |
