Near-surface 2D seismic survey in the transition zone near Sakhalin island: case study

This paper is based on the results of shallow 2D seismic survey performed in the transition zone (land-shallow water) at the construction site of a bridge between mainland and Sakhalin Island (Eastern Russia). The purpose of the research was to obtain geological sections in the transition zone, that are necessary for further linking of marine and land seismic data. A special attention was given to assumptions on location of the upper boundary of a rocky base.
