1. An observation system for the re-suspension quantity of submarine sediments by deep-sea internal waves, comprising:

  • a submarine observation platform frame located at a bottom of the system,an anchor mooring counterweight located below the submarine observation platform frame, anda mooring rope arranged vertically,wherein the anchor mooring counterweight is a cuboid gravity anchor provided with a fixed ring in a middle of an upper surface, and floating materials are arranged at a top of the submarine observation platform frame;

    the submarine observation platform frame is equipped with a turbidity meter, a sediment catcher, a high-precision temperature and salinity detect a single-point current meter and two acoustic release transponders connected in parallel;

    upper ends of the two acoustic release transponder are connected with the submarine observation platform frame, and lower ends of the two acoustic release transponder are connected through a rope penetrating through the fixed ring;

    the mooring rope has a bottom end connected with the submarine observation platform frame and a top end connected with a first glass floating ball assembly;

    a second glass floating ball assembly, a release ring and a main floating body are sequentially arranged on the mooring rope from the bottom end to the first glass floating ball assembly at the top end;

    two or more auxiliary floating bodies are mounted at different positions of the mooring rope;

    the main floating body is located in a middle of the mooring rope and is equipped with two acoustic Doppler current profilers, wherein one of the two acoustic Doppler current profilers faces upwards and is configured for observing a flow field above the main floating body, and an other one of the two acoustic Doppler current profilers faces downwards and is configured for observing a flow field below the main floating body, allowing achieving full-depth flow measurement from a sea surface to a seabed;

    a flow measurement layer has a thickness of 8-24 m; and

    each said auxiliary floating body is equipped with a turbidity meter and a high-precision temperature and salinity detector.
