Speleonaut
''Speleonaut'' (named from the Greek words for "cave" and "sailor") is the submersible used by the cave diver Jochen Hasenmayer. After the 1989 decompression accident that left his legs paralyzed, Hasenmayer designed the ''Speleonaut'' with his friend Konrad Gehringer in order to continue exploring the Blauhöhle cave system, which begins at the base of the Blautopf spring in the Swabian Jura mountain range. The ''Speleonaut'' is wide and has nine engines, making it easy to maneuver in all directions. It is the first submarine designed specifically for the exploration of caves. According to Hasenmayer, the ''Speleonaut'' has been tested in Lake Constance Lake Constance (, ) refers to three bodies of water on the Rhine at the northern foot of the Alps: Upper Lake Constance (''Obersee''), Lower Lake Constance (''Untersee''), and a connecting stretch of the Rhine, called the Seerhein ().

Jochen Hasenmayer
Jochen Hasenmayer (born 28 October 1941 in Pforzheim, Germany) is a German speleologist and cave diver from Birkenfeld in Baden-Württemberg, whose spectacular dives have frequently made headlines. Cave diving Hasenmayer began his cave diving career in 1957 at the age of fifteen, exploring the Falkensteiner Höhle near Stuttgart. Beginning in the 1960s, Hasenmayer explored many karst springs and caves in the Swabian Jura and elsewhere in Southern Germany, including the Wimsener Höhle, the Aachtopf and the Blautopf. He became famous in 1985 due to the discovery of the ''Mörikedom'' ("Mörike Cathedral", named after the German pastor and poet Eduard Mörike), the second big air-filled chamber in the Blauhöhle, about into the cave system. Some of his terminuses (farthest point reached in a cave) have not been exceeded. In the late 1970s, Hasenmayer was among the divers who searched for an underwater connection between Kingsdale Master Cave and Keld Head in the Yorkshire D ...

Konrad Gehringer
Konrad Gehringer (4 June 1939 – 12 December 2003) was a German car mechanic and bus driver who had a one-man operation for producing electronic organs in Pforzheim, Germany. Gehringer was best known as the inventor and developer of the one-man submersible ''Speleonaut'', the first submarine designed for cave diving. The ''Speleonaut'' was designed in collaboration with Gehringer's friend, the cave diver Jochen Hasenmayer, who has used it since 1996 to explore the Blautopf The Blautopf (German for ''Blue pot'') is a Spring (hydrosphere), spring that is considered the source of the river Blau (Danube), Blau in the karst landscape on the Swabian Jura's southern edge.

Blauhöhle
The Blauhöhle is the largest known cave system in the Swabian Alps in southern Germany. The Blauhöhle presumably originated in a time when the Danube still flowed through the Blau valley. Since the shifting of the Danube, several small rivers, the Schmiech, the Ach, and the Blau, have flowed through this valley. The cave system begins about 21 meters under water at the base of the Blautopf. It continues west and northwest, rising and falling several times until after a horizontal distance of about it comes above the level of ground water and opens into the second big air-filled chamber. The maximum depth of the cave under water is . This chamber was first discovered in 1985 by Jochen Hasenmayer, who named it ''Mörikedom'' (Mörike Cathedral, named after Eduard Mörike). Hasenmayer's diving accident in the Wolfgangsee resulted in a long break in its exploration. For several years the cave has been explored by the ''Arbeitsgemeinschaft Blautopf'' (Blautopf Study Group, or C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cave Diving
Cave-diving is underwater diving in water-filled caves. It may be done as an extreme sport, a way of exploring flooded caves for scientific investigation, or for the underwater search and recovery, search for and recovery of divers or, as in the Tham Luang cave rescue, 2018 Thai cave rescue, other cave users. The equipment used varies depending on the circumstances, and ranges from Free-diving, breath hold to Surface-supplied diving, surface supplied, but almost all cave-diving is done using scuba equipment, often in specialised configurations with engineering redundancy, redundancies such as Sidemount diving, sidemount or backmounted twinset. Recreational cave-diving is generally considered to be a type of technical diving due to the lack of a free surface during large parts of the dive, and often involves planned Decompression (diving), decompression stops. A distinction is made by recreational diver training agencies between cave-diving and cavern-diving, where cavern diving i ...

Submarines Of Germany
A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or informally to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub). Submarines are referred to as ''boats'' rather than ''ships'' regardless of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and submarines were adopted by several navies. They were first used widely during World War I (1914–1918), and are now used in many navy, navies, large and small. Their military uses include: attacking enemy surface ships (merchant and military) or other submarines; aircraft carrier protection; Blockade runner, blockade running; Ballistic missile submarine, nuclear deterrenc ...

Lake Constance
Lake Constance (, ) refers to three bodies of water on the Rhine at the northern foot of the Alps: Upper Lake Constance (''Obersee''), Lower Lake Constance (''Untersee''), and a connecting stretch of the Rhine, called the Seerhein (). These waterbodies lie within the Lake Constance Basin () in the Alpine Foreland through which the Rhine flows. The nearby '' Mindelsee'' is not considered part of Lake Constance. The lake is situated where Germany, Switzerland, and Austria meet. Its shorelines lie in the German states of Baden-Württemberg and Bavaria; the Swiss cantons of St. Gallen, Thurgau, and Schaffhausen; and the Austrian state of Vorarlberg. The actual locations of the country borders within the lake are disputed. The Alpine Rhine forms, in its original course ( Alter Rhein), the Austro-Swiss border and flows into the lake from the south. The High Rhine flows westbound out of the lake and forms (with the exception of the Canton of Schaffhausen, Rafzerfeld and Bas ...
