Not AvailableThe knowledge of the sound distribution in the sea is of importance in fathmetry and in sonar studies. It is with a view to find the corrections to various echo-sounders with different 'sounding velocities' for use in the Arabian Sea, along the South-Western coast of India, this study has been undertaken. As a preliminary, the results for the period immediately after the South-West monsoon only, are given in this paper. As it would be of interest for further studies in locating the subsurface barriers by sonic method and because of the importance of the sound velocity in under-water acoustics, the distribution of sound velocity is fully discussed without making any special reference to the individual problems.Not Availabl
