Abstract: This paper introduces in detail the development process, current situation, and outlook of geophysical data processing technologies used in Qingdao Institute of Marine Geology. The key geophysical processing technologies, such as multi-beam high-precision imaging and acoustic information extraction, gravity and magnetic data processing and interpretation, shallow water high-resolution sub-bottom profiling / single-channel seismic processing, low signal-to-noise ratio small-interval multi-channel seismic imaging, long-spread and multi-channel seismic data processing, three dimensional hydrate seismic processing, and geophysical inversion and target recognition, are summarized and the future development prospect of these data processing technologies are envisaged. These technologies have been successfully applied to marine basic geological survey, coastal zone survey, deep-sea geological survey, and oil- gas and hydrate resource exploration projects, providing good supports to marine geological survey and research.
