The publication contains Section VI of the Oceanographic Atlas of the North Atlantic Ocean. Presented in this section is the sound velocity structure in the North Atlantic Ocean from the Equator to 68 deg. N and Caribbean, Gulf of Mexico, southern portion of the Norwegian Sea, North Sea, Baltic Sea, Mediterranean, and Black Sea. The primary source of information for this atlas was machine processed serial oceanographic data from the historical files of the National Oceanographic Data Center (NODC). These data include all serial stations for the North Atlantic Ocean and its adjacent seas for the period beginning some time in 1902 to 1 August 1962. Sound velocity information was computed from temperature, salinity, and depth data according to the equation developed by W. D. Wilson. The atlas was preceded by U. S. Naval Oceanographic Office Technical Report 171, 'An Interim Report on the Sound Velocity Distribution in the North Atlantic Ocean,' in which a selected group of 488 sound velocity profiles was analyzed by a method similar to the one used herein. Results agree very well, especially in low latitudes. Increasing the data input approximately fortyfold broadened the sound velocity envelopes slightly, necessitated relocation of some boundaries in the North Atlantic, and of course, greatly increased the confidence level of this atlas.
