摘要：

The author presents the results of experiments on compressing / decompressing the data describing sea-bottom structure by means of lossless compression based on LZ77 and PPM. In order to increase the compression ratio, the input data were transformed (reordered) and stored in a differential form. These data were then compressed in a standard way. The results lead to a proposition of a lossless compression method of sea-bottom data.
