A bathyscape, bathyscaphe, or bathyscaph is a free-diving self-propelled deep-sea diving submersible, consisting of a crew cabin similar to a bathysphere suspended below a float (rather than from a surface cable, as in the classic bathysphere design) Image File history File links No higher resolution available. ...

The float is filled with petrol (gasoline) because this is readily available, buoyant, and for all practical purposes, incompressible. The incompressiblity of the petrol means the tanks can be lightly constructed as the pressure inside and outside of the tanks equalises and they are not required to withstand a significant pressure differential. Buoyancy can be trimmed easily by replacing petrol with water, which is denser. To descend, a bathyscaphe floods air tanks with sea water but unlike a submarine the water in the flooded tanks cannot be displaced with compressed air to ascend because the water pressures at the depths for which the craft was designed to operate are too great. For example, the pressure at the bottom of the Challenger Deep is more than seven times that in a standard "H-type" compressed gas cylinder. Instead, ballast in the form of iron shot is released to ascend, the shot being lost to the ocean floor. The iron shot containers are in the form of one or more hoppers which are open at the bottom throughout the dive, the iron shot being held in place by an electromagnet at the neck. This is a fail-safe device as it requires no power to ascend; in fact, in the event of a power failure, shot runs out by gravity and ascent is automatic.

Auguste Piccard, inventor of the first bathyscaphe, composed the name bathyscaphe using the Greek words bathys ("deep") and skaphos ("ship"). Auguste Piccard (1927) Auguste Antoine Piccard (January 28, 1884 – March 24, 1962) was a Swiss physicist, inventor and explorer. ...


The first bathyscape was dubbed FNRS-2, named after the Fonds National de la Recherche Scientifique, and built in Belgium between 1946-48 by Piccard. Propulsion was provided by battery-driven electric motors. The FNRS-2 was the first ever bathyscaphe built. ... The National Fund for Scientific Research (NFSR) (Dutch: NFWO, French: FNRS) is a government institution in Belgium for supporting scientific research. ... Electric motors of various sizes. ...


Piccard's second bathyscaphe was Trieste, which was purchased by the U.S. Navy in 1957. It had two water tanks and held 120,000 litres of petrol in eleven tanks for buoyancy [1]. In 1960 Trieste, carrying Piccard's son Jacques Piccard and Lt. Don Walsh, reached the deepest point on the earth's surface, the Challenger Deep, in the Mariana Trench. As of 2006 the two remain the only people to reach this extreme depth. The onboard systems indicated a depth of 37,800 ft (11,521 m) but this was later corrected to 35,813 ft (10,916 m) by taking into account variations arising from salinity and temperature. Later and more accurate measurements made in 1995 have found the Challenger Deep to be shallower at 35,798 ft (10,911 m). The bathyscaphe Trieste Trieste was a Swiss designed deep-diving research bathyscaphe (deep boat) with a crew of two people, which reached a record-breaking depth of about 10,900 m (about 35,760 ft), in the deepest part of the oceans, the Challenger Deep, in 1960. ...
