Of current interest: Closed-circuit television proved effective in underwater research

AN UNDERWATER APPLICATION of closed-circuit television, which is enabling the U. S. Fish and Wildlife Service, Department of the Interior, to observe and test the performance of experimental fishery methods and equipment under actual oceanic conditions, was reported recently by Theodore A. Smith, vice-president and general manager of the engineering products division, Radio Corporation of America (RCA). The application represents the first practical demonstration in the United States of underwater television as a research tool for experimental, work in fishery operations, and gives promise of a wide range of uses in marine biology and explorations.
