Abstract

Abstract

Both the parametric array and spark source sub-bottom profilers have high resolution.Bycomparing the working principles and measured profiles, it is found that parametric array and the spark source sub-bottom profilers do not interfere with each other. And the ghost wave effect of the spark source may cause difficulties in the interpretation of the sub-bottom profilers within 10m below the seabed, while the parametric array sub-bottom profiler has a very high resolution in the profilewithin 10m.The good complementarity of the two methods makes us possible to use them in the geo- logical survey offshore, and the accuracy of regional geological survey can be much improved.
