Abstract Research on seabed classification and recognition is of great significance.The reflection intensity of sub-bottom profile data is mainly related to the seabed sediment types.In this paper,the authors selected a sub-bottom profile data in the South China Sea as the study object,drew the contour map by extracting the RMS amplitude of the sub-bottom profile data and analyzed the macroscopic characteristics of the seabed sediment in the study area.Compared with deep sea video recording,the method of seabed amplitude characteristic attributes of sub-bottom profile data is suitable for direct seabed analysis.
