Description During the cruise 190 of R.V. Gaveshani, the sparker signal was recorded in the analog form on audio cassettes. This signal has been digitized and a statistical computation, viz. the normalized cross-correlation function between successive echoes, has been determined from it. The normalized cross-correlation function is used to calculate the amount of coherence between consecutive echoes. The values computed are differentiated into different groups based on the reference classification of Drapeau and King (1972) and Fader et al. (1977). The results obtained helped in determining the sediment type
