커버이미지 없음

&nbsp;&nbsp;A marine seismic exploration with the 400㎐ bubble pulser 1200 system was carried out.<BR>&nbsp;&nbsp;The seismic survey was conducted along the 5 survey lines(total length of 4㎞), and the aim of this survey was to profile depth of sediment layer and bedrock with SINCDAS(Single Channel Data Acquisition System) developed by this study. The field data is displayed with variabel-density method and compared with borehole log to confirm accuracy of seismic data interpretation.<BR>&nbsp;&nbsp;The subsurface structure consists of the upper clay layer and the lower silt-clay layer. But the bedrock depth is not found because of extremely shallow survey depth and multiple reflections.
