Abstract : The document reports the first test results with the underwater test facility called Helgoland. The document gives technical data and description of the newly designed and built laboratory, how the atmosphere is controlled, communication systems, etc. There is an underwater depot close by to the underwater laboratory to house in greater quantities the necessary commodities, such as Silica gel, Limestone. 38 m away from the underwater laboratory there is the so called Iglu submerged where the aquanauts take their rest periods. From here they have telephone communications with the laboratory. The report also describes how the underwater laboratory is supplied with the necessary gases and electric power; television, telephone, telegraph and other communication systems with the outside world. Safety devices are described, e.g., a one man rescue chamber brings a person to land in case of emergency. The Helgoland underwater laboratory has been designed and built after an electrical model which modeled the gas-transport in the organism was studied. The idea of the laboratory was prompted when mineworkers were rescued with a special appratus (Dahlbuschbombe) which brought them up into a decompression chamber where they underwent slow decompression.
