Description

technical field [0001] The invention belongs to the technical field of marine environment monitoring. The invention relates to an artificial upwelling marine environment multi-parameter real-time continuous three-dimensional monitoring system. Background technique [0002] Natural upwelling is a key ocean physical process, which can bring nutrient-rich deep seawater to the middle and upper layers, so that the primary productivity of the ocean in the upwelling area reaches 6 times that of the ocean, and the fish production reaches 75 times that of the ocean. Make the upwelling area a region with higher marine productivity in the world, so that on the one hand, fishery output can be increased, and on the other hand, the marine ecological environment can be improved. [0003] Artificial upwelling is a geoengineering method that uses some devices to lift the deep seawater with low temperature and rich nutrients to the surface, so that the upper layer contains lower nutrient sal...

AI Technical Summary

Problems solved by technology

At present, the monitoring station can collect some data periodically, but the measurement parameters are mainly temperature, salinity, dissolved oxygen, etc., and the amount of data is limited, which cannot meet the requirements of three-dimensional monitoring; the monitoring ship can observe at fixed points, but it is expensive and cannot meet the long-term observation The advantages of satellite remote sensing monitoring are large monitoring range, all-weather, easy processing and translation of image data, real and continuous quantitative monitoring, etc., but the repeated observation cycle is long and the spatial resolution is low, so it is limited to a certain extent

Chinese patent CN 201497507 U discloses a full-section monitoring system of marine elements, which is organically combined with a buoy observation device and a submerged buoy observation system, which can realize observation from the sea surface to the bottom of the sea, and can realize the requirements of multi-parameters, but does not meet the horizontal distribution requirements

Chinese patent CN 201397138Y discloses a real-time monitoring system for the polar near-shore marine environment, which transmits electric energy and signals through cables, and can continuously and real-time monitor the polar near-shore sea areas for a long time. Meet the requirements of horizontal deployment

Since the artificial upwelling system is far away from the shore and requires overall horizontal and vertical data, the above two patents cannot be well applied to the artificial upwelling system

In summary, the existing monitoring methods are difficult to meet the real-time, continuous, three-dimensional, and long-term monitoring requirements of the artificial upwelling marine environment, and cannot be directly applied to the monitoring of the artificial upwelling marine environment.
