Abstract : A Hewlett Packard 67 (or 97) calculator program used to convert a bathythermograph trace to a sound profile was evaluated. The program was found to use a truncated form of Leroy's equation, adequate over the shallow depths ( 2000 meters) considered. However, use of a constant oceanic-wide salinity value was found to give erroneous estimates of the layer depth and the depth of the deep sound channel axis in ocean areas where moderately large vertical salinity gradients are encountered. This result led to the recommendation that the program be rewritten to allow the use of a salinity profile representative of the are being sampled. (Author)
