Experiment and Application of A Aparker Source in Seismic Exploration in Coastal Tidal Flats

Abstract

We investigate a field experiment in coastal tidal flats in Jiangsu Province using a sparker source, to test the seismic data acquisition system and detect the shallow layers in the real scenarios. We also compare the geophones with 60Hz and 10Hz natural frequency in shot gather as well as in stacked profiles. We process the different data separately, and then process them together in a wide-line mode. As predicted, the fold is doubled showing a higher signal to noise ratio. Through the routine multi-domain integrated noise removal and effective data processing, the signal-to-noise ratio and resolution of the seismic data get largely improved, and thus we successfully obtain the high-quality seismic profiles. The practical experiment results are of importance for shallow geological and environmental detections, as well as for geo-hazard prevention study in the related areas.
