Helgoland Habitat
The underwater laboratory " Helgoland" is a former German submarine station, and the first dive stationary system for saturation diving for use in colder waters.
History
The underwater laboratory (UWL ) was built in 1969 by the company Dräger in Lübeck on behalf of the Biologische Anstalt Helgoland. After gaining experience from the first use of a wet room was cultivated in 1971.
In 1972, the station was handed over to the GKSS Research Centre in Geesthacht. From this it was used until 1981 in the Baltic Sea, the North Sea and the North Atlantic. First stop of the insert was 1969 off Helgoland. In this application, the island of Karl- Heinz Schumann and the student Winfried Kreytenberg came on 6 December 1969 in 25 feet of water southeast dune when working on the underwater laboratory killed; they should release the connection between underwater laboratory and supply tonne. The laboratory was founded in April 1970 by a floating crane " Magnus 4" and placed on the pier in South Haven Helgoland.
Other stations in 1971 before Eckernförde nine meters in 1973 again off Helgoland in 23 feet of water, 1974 in Lübeck Bay in 15 feet of water in 1975 against Rockport at 33 meters depth, as well as in the years 1975 to 1981 respectively, in the Bay of Lübeck in water depths of between eleven and 15 meters.
1998 gave the GKSS Research the UWL as a gift to the German Oceanographic Museum. It was transported by water from Geesthacht to Stralsund, where it has since been exhibited in Nautineum Stralsund.
Specifications
The UWL contained in a relatively small space all the necessary facilities for a stay of several weeks of marine scientists on the seabed. The pressure inside equal to the outside pressure; decompression was performed at the end of the insert.
The underwater laboratory has air conditioning and a good thermal insulation. The laboratory was lowered by flooding the ballast tanks with seawater; the appearance of the water pressed from the tanks using compressed air.
