Abstract : All available sound velocity data in the North Atlantic Ocean between 15 degrees and 65 degrees N. latitude and east of 65 degrees W. longitude (excluding the Labrador Sea) have been analyzed in terms of the seasonal areal extent and average axial depth of the upper sound channel, the annual areal extent and average depth of the subsurface sound velocity maximum, and the annual average depth of the deep sound channel axis. The vertical extent of these and other sound velocity structures are shown on nine north-south and nine east-west sound velocity cross-sections that extend to a maximum depth of 5000 meters. These cross sections include four winter/summer pairs along the same meridian and three winter/summer pairs along the same parallel. In addition, sound velocity/temperature-salinity comparisons for winter and summer are given for 50 locations throughout the North Atlantic Ocean. (Author)
