Abstract : This report gives an account of the use of the deep submergence research vehicle Deepstar 4000 by the U. S. Navy Underwater Sound Laboratory during the period 1 July to 23 October 1967. The report has been divided into two major sections: an overview of the planning and operation of the program, and a general summary of the research conducted during the operation. Operation Deepstar consisted of 53 scientific research dives conducted along a 2500-mile track from the Gulf of Mexico to south of Newfoundland. Research dives were made to obtain data concerning (1) surface, bottom, and volume reverberation, (2) the biological composition of the deep scattering layer, (3) detailed physical features of the ocean bottom, (4) ambient electromagnetic noise in the sea, (5) ambient acoustic noise, and (6) the applicability of DRV's for target strength measurements.
