SKEWNESS AND CORRECTION METHOD OF THE SUBBOTTOM PROFILE FROM VERY SHALLOW SEA WATER ZONE

Liu Jinjun Qi Guojun(Institute of Marine Geology,MGMR,Qingdao,266071,China)  
Subbottom profiling is an important method of continental-shelf Quaternary geolo-gy,hazardous geology and engineering geology. The quality of a profile and the correct-ness interpretation can directly influence reliability of study results.The subbottom pro-file system is only a close-to single-track system that vertically emits and receives sig-nals,as there is some distance between hydrophone and seismic source.Too shallow wa-ter can lead to skewness of a profile due to delay of reflection time from horizons,short-ening of travelling time from one horizon to another,too big the interval velocity calcu-lated and rough relief.And meeting points of a profile cannot close if the profiling isdone in an area where tidal range is big. So,correction of subbottom profiles acquired atshallow sea water is very necessary.
