Abstract: This paper briefly summarized the current status, application scopes, main problems and development trends of marine geological and geophysical survey technology. It is observed that the technology for marine geological/geophysical survey will move step by step towards visualization, integration, automation, digitization and underwater dynamic positioning. The marine geophysical survey technology will further develop from offshore survey to deep sea exploration, from shipborne operation to near-seabed and in-situ observation, and from single exploration technology to integrated and refined exploration technology as well as multi-directional and three-dimensional comprehensive survey technology.
