Navy Cable-controlled Undersea Recovery Vehicle ( CURV-III) was deployed within 24 hours 6,000 miles from its home base.
Through an international effort of the United States, Canada, and Great Britain, the U.S. Initial rescue efforts by Pisces III sister submersibles were unsuccessful. It sank to the bottom of the ocean with its two-man crew, Britons Roger Mallinson and Roger Chapman, stranded at a depth of 1,575 feet (480 m) and 72 hours of available life support, which they were able to extend to 76 hours by careful conservation. Pisces III was being used to bury cable and repeaters of the CANTAT-2 transatlantic telephone cable on the sea bottom off Ireland in 1973 when a buoyancy tank was inadvertently flooded. Main article: Rescue of Roger Mallinson and Roger Chapman Pisces II was the first production model of the design and was completed in 1968, with 9 more Pisces subs built before the manufacturer folded in the late 1970s.
Ut project pisces series#
Designed by Allan Trice, the Pisces series of submersibles are representative of early crewed submersibles built in the late 1960s and were proven workhorses in offshore exploration and oceanographic research. The pressure hull has a 7 ft (2.1 m) inside diameter and is made of HY-100 steel with 3 forward-looking acrylic windows, 6 in (15 cm) in diameter.
The vehicles have multiple view ports, sample collecting, environmental sensing, and instrument placement capabilities. Pisces class submersibles are three person research deep-submergence vehicles designed and built by Hyco International Hydrodynamics of North Vancouver in British Columbia with a maximum operating depth of 2,000 m (6,560 ft).

Ut project pisces software#
The software standardizes and stores the source data. PISCES is both software and a database containing information of fish species distribution in California historically, and in the present, according to primary source data, models, and leading experts. PISCES was developed with funding from the USDA Forest Service Region 5 and in collaboration with numerous experts in fish biology and distribution in California. This site contains exported data for those taxa, but does not yet include compiled maps. As of September 2012, it includes data on about half of the state's 129 native fish taxa. The data are compiled from multiple sources and experts and is stored and exported as rangemaps and summary maps. PISCES is software and data describing the best-known ranges for California's native fish.
