High-resolution multi-channel marine seismic survey using a sparker source

  A sparker source with the center frequency of 1㎑ or higher can not be easily applied for the multi-channel marine seismic survey because of stacking difficulties. Thus, it has been applied mainly to the single channel marine seismic survey. For examining the applicability of sparker source to multi-channel marine seismic survey, 8-channel seismic data were obtained from the field and processed, and a 2-D seismic section was drawn up. From this study it can be concluded that, a sparker source with the center frequency of 1㎑ or higher can be applied to the multi-channel marine seismic survey, and the seismic section with high vertical resolution can be generated. The high-resolution seismic section would be very useful for subsurface geological structure analysis in the shallow sea.
