Konstruktive Probleme Der Ozeanographischen Forschung

Following a prelirninary reference to the scientific and economic signifi­ cance of oceanographic research, the various technological methods of subaqueous research are being dealt with. The limits imposed on diving depth and diving time respectively can be considerably increased by under­ water vehicles and underwater houses. This provides for the "deepening" of oceanic research and an expansion of the possibilities of oceanic ex­ ploitation. The buoyancy and ballast systems as weH as the design principles are discussed on the strength of existing bathyscaphes. The crucial point of the expositions rests with the treatment of problems involved with stress and design as are encountered in underwater schemes. Besides an American and a French underwater laboratory there is detailed reference to a German underwater laboratory, presently under construction off Helgoland at an initial depth of 20 m, planned to be taken into operation during the summer of 1969. Resume Apres une breve introduction concernant la signification scientifique et economique de la recherche fondamentale oceanographique, l'auteur expose les differentes methodes technologiques de recherche sous-marine. Les limites des profondeurs et des temps de plongee peuvent etre considerable­ ment accrues a l'aide de stations et d'engins sous-marins. 11 en resulte un « approfondissement» de la recherche fondamentale des mers et des oceans ainsi qu'un elargissement de leurs possibilites d'exploitation.
