Abstract

Fiber optic distributed acoustic sensing (DAS) is a novel technology for seismic data acquisition and particular suitable for vertical seismic profiling, near surface structure imaging and natural seismic monitoring. In this paper, a series of field trials verifying the performance of DAS for detecting marine seismic data are conducted in the geological condition of lagoon. The results show DAS can detect surface waves and longitudinal waves generated by artificial earthquake, and the surface waves have higher main frequency and wider bandwidth and the wave field information of seismic data is more abundant compared to geophone under the same source and the same offset condition.
