The invention relates to an underwater control system for a seabed hydrothermal fluid and cold spring observation subsurface buoy and a relevant observation method and belongs to the technical field of ocean observation. By the adoption of the underwater control system for the seabed hydrothermal fluid and cold spring observation subsurface buoy and the relevant observation method, the problem that actual maritime observation of the physical and chemical characteristics of a hydrothermal fluid and cold spring spout cannot be achieved at present is solved. The underwater control system for the seabed hydrothermal fluid and cold spring observation subsurface buoy comprises a main control chip, a wireless positioning module, a power supply module, an acoustic communication module, an acoustic beacon module, a hydraulic control module, a load rejection control module, a microstructure measurement module and a conductance-temperature-depth (CTD) module. All the modules are connected with the main control chip. The method for achieving seabed hydrothermal fluid and cold spring observation by controlling the subsurface buoy comprises the steps that initialization is conducted, all the modules are started to measure surrounding parameters, and data are stored and transmitted in real time; the subsurface buoy is controlled to dive, be located in a fixed-depth position and float upwards; and the subsurface buoy is recovered. By the adoption of the underwater control system for the seabed hydrothermal fluid and cold spring observation subsurface buoy and the relevant observation method, structural measurement of the physical fields such as the temperature, the salinity and the depth of the area of the hydrothermal fluid or cold spring spout can be achieved; meanwhile, the working state of the subsurface buoy can be monitored in real time, and the task planning of the subsurface buoy can be adjusted in real time.
