This paper studies the interpretation of high-resolution shallow seismic profile. Firstly, it is necessary to do some indoor fine processing to get a high quality profile, such as adaptive filtering, true amplitude recovery, tides differences and so on, especially the processes to remove the multiple waves. Based on the theory of seismic stratigraphic and combined with the previous survey data and drilling information, eight major targets are interpretated to describe quaternary sediment of this study area. Meanwhile, this paper analyzes the feature and the possible stratigraphic time of each layer. In addition, the database for interpreting is created by using the human-computer interaction way in a workstation, which makes the recognition of the characteristics of sedimentary layers much easy.

The variable period reverberation which is caused by undulating seabed topography is the main disturbance in neritic area seismic exploration. This paper analyzes the forming course of variable period reverberation in theory, deduces the formula which is about the frequency features of variable period reverberation and discusses the frequency features of period reverberation when the cable and seismic source are in the different water depth. A model for the study of featuers of veriable period reverberation is discribed. The results shows that the modeling results accords well with the computing results in theory. The study can play an important role in removal of reverberation from marine seismic records.
