Oceanographic and Underwater Acoustics Research
Abstract
Investigations were continued in a broad program of research in physical oceanography, submarine geophysics (including underwater sound), and submarine geology. Dr. Voorhise, using the temperature and pitotmeter current- shear measurements from the thermistor chain, found an equatorial counter- current in the Atlantic similar to the Cromwell current of the Pacific. Miss Bunce, Mr. Parker, and others in an intensive bathymetric survey found the channel (minimum depth cir. 2000 fms.) through the MidAtlantic Ridge by which cold water passes from the western Atlantic basin into the eastern Atlantic, and Miss Bunce, and Mr. Crampin successful measured the thickness of the continental crust, 23 km to a layer having a seismic velocity of about 7.6 km/ sec, under the continental shelf south of Ireland. Analysis of acoustical, geophysical, geological, and bioacoustical data proceeded as rapidly as possible in competition with the sea-going program. (Author)
