Abstract: The application of artificial intelligence algorithm in marine geology is a very popular research direction at present, and it has been applied in many directions such as marine geological survey, marine geological disaster evaluation, and marine geological modeling. Marine engineering geological survey is the basis of marine engineering geological research, and the refinement and automatic processing of data has a very important role in data mining and efficiency improvement. This paper firstly introduces the historical development brief and research status of artificial intelligence, neural network, machine learning and deep learning, and summarizes the relationship among them. Then an overview of the application of artificial intelligence in the field of marine geology and engineering geology is given, which mainly includes geophysical survey, geological sampling, and geological hazard evaluation. The results show that AI algorithms can be better applied to various problems such as geophysical survey, geological sampling, and geological hazard evaluation, only that they are less applied in the field of marine engineering geology at present. Finally, the application prospects and future outlook of artificial intelligence in the field of marine engineering geology were elaborated, summarizing several major constraints that currently exist and providing suggested scientific guidance on the future development direction.
