As an irreplaceable high-tech advanced equipment and emerging equipment for ocean observation and exploration,marine unmanned autonomous observation equipment is the pioneer of ocean observation and exploration field. Improving ocean mobile observation capabilities based on marine unmanned observation equipment is an important technical means for building a three-dimensional,continuous,and real-time underwater observation network in the future. The development and use of marine unmanned autonomous observation equipment will profoundly affect the way of ocean observation and exploration in the future. Based on the analysis of the development and application status of marine unmanned observation equipment at home and abroad,the main problems and gap in the development of marine unmanned observing equipment of our country is considered,and the future development and application of marine unmanned observing equipment is expected.
