Abstract: The study of deep ocean geology, as one of the major trends of world scientific research, is critical important in both the scientific research and social development. In order to explore the research status of deep ocean geology of the world, their research hotspots and frontiers, the software of CiteSpace was selected by the authors to analyze the papers in the Web of Science Databases. The results suggest that this approach is still in the stage of development and has broad research and application potentials. It entered a rapid development stage in the years around 1990s. Developed countries such as some European countries and the United States have made outstanding achievements in the field. Although China has made great progress in recent years, there is still a long way to go. Papers on deep ocean geology are still not closely linked and improvement is required. Tectonics and sedimentology remain the hot disciplines. Geochemistry and geophysics have become the popular research methods. Submarine canyons are the hot research areas and the Holocene is the main era for research.
