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.
