Abstract: A device for monitoring deep-sea sediment environment in mining polymetallic nodules is provided. The monitoring system includes: acoustic Doppler flow profilers, a self-potential probe, a turbidity meter and an underwater camera. The invention can realize long-term in-situ observation of sediment disturbance, and can realize the mechanical recovery of probe rod-type equipment without large-scale mechanical devices, thereby reducing the overall weight of the recovery equipment and increasing the probability of successful equipment recovery. Compared with the existing long-term in-situ observation equipment on the seabed, it is more environmentally friendly, efficient, energy-saving and reliable.

Abstract: The present invention relates to the technical field of long-term in-situ monitoring of sediment disturbance in deep-sea surface mineral mining, and more particularly to a device for monitoring deep-sea sediment environment in mining polymetallic nodules. The monitoring system comprises: acoustic Doppler flow profilers, a spontaneous potential probe, a turbidity meter and an underwater camera. The invention can realize long-term in-situ observation of sediment disturbance, and can realize the mechanical recovery of probe rod-type equipment without large-scale mechanical devices, thereby reducing the overall weight of the recovery equipment and increasing the probability of successful equipment recovery. Compared with the existing long-term in-situ observation equipment on the seabed, it is more environmentally friendly, efficient, energy-saving and reliable.
