Distortion and Correction of C-Boom Subbottom Profiles From the Shallow Sea Areas

Subbottom profile survey is an important means for marine engineering survey,hazardous geological investigation and continental shelf geological research.The accuracy of profile interpretation can directly influence the reliability of the results from geological investigations.Because the transducer and the hydrophone of the C-Boom Subbottom Profiler are mounted separately,stratum distortion can be caused if the profiler is seen as a self-excited and collected single-channel seismic system,particularly when water depth is very shallow in the surveying area,and the shallower the water depth,the greater the stratum distortion rate.According to the basic principle of the profiler,formula for calculating the stratum distortion rate and correcting the stratum distortion have been worked out for the C-Boom Subbottom Profiler,hence providing helpful references for using C-View software to interpret such profile data more accurately.
