Digital processing of marine seismic data

The enormous amount of marine seismic data makes it necessary to process the data with a high speed digital computer. This paper is concerned with the application of digital signal processing techniques to the marine seismic data. The objectives of the study are two-fold: (1) to improve the data, i.e. to enhance the signal-to-noise ratio of the data and (2) to reconstruct the seismic profile from the digitally filtered data for a better interpretation of the ocean bottom and the subbottom structure. Cepstrum analysis, deconvolution, and Walsh domain processing of the data are discussed and the unpublished computer results are presented in detail.
