Description

technical field [0001] The invention relates to the technical field of marine monitoring equipment, and relates to an instrument capable of detecting covering most of the ocean, in particular to a surface drifting buoy data acquisition controller capable of monitoring ocean subsurface currents and their flow paths. Background technique [0002] Surface drifting buoys (hereinafter referred to as buoys) are marine instruments that drift with the current, use the Argos satellite system for positioning, and have real-time data transmission functions. The buoys are equipped with temperature sensors to obtain surface water temperature, and use the Lagrangian method to measure surface velocity on a large scale and track the trend of ocean currents, and thus analyze the distribution characteristics of ocean currents in the observed sea area and the surface temperature of the water body, and further understand and understand the surface ocean currents and their flow paths in the obser...

Problems solved by technology

After 2000, with the efforts of some scientific researchers in my country, marine monitoring equipment suitable for my country's national conditions has gradually been put into use. However, it has been found through practice that the existing buoy equipment has the defects of single function and large power loss.
