System Composition

1) The system adopts a single point tensioning anchor system, which is suitable for long-term observation in waters with a depth of 1500-6000m;

2) The main float can be equipped with 2 TRDI LongRanger 75KHz ADCPs; One unit measures the layered vertical current profile of the main float up to the sea surface;

Measure the vertical ocean current profile of the main float about 500m downwards with one unit.

3) Multiple SBE37 CTDs can be configured on the anchor rope to measure the temperature, salinity, and pressure of seawater in the water layer of interest.

Multiple SBE56 T are installed on the anchor rope to intensively measure the seawater temperature of the water layer being monitored.

Multiple TRDI DVS are installed on the anchor rope to measure single point ocean current parameters (such as turbulence parameters) of the water layer of interest.

4) All measuring instruments used are powered by underwater battery packs and perform long-term, continuous measurements in a self capacitive manner.

5) Install one Evo Logics S2C acoustic communication machine underwater on the main float, and integrate it with two ADCPs to communicate with the Evo Logics S2C acoustic communication machine placed on the scientific research vessel. Send the data of the two 75KHz ADCPs to the scientific research vessel.

The deep-sea submersible buoy system consists of measuring instruments, anchoring systems, and acoustic communication systems.

1) The measuring instrument consists of 2 TRDI Long Ranger 75KHz ADCPs, multiple SBE37 CTDs, multiple TRDI DVS, and multiple SBE56 T sensors.

2) The anchor system consists of one Flotec 49 "main float, wireless beacon and receiver, flashing beacon, multiple Flotec 18" solid floats, multiple NMS-FS-6700 17 "glass floats, three EdgeTech ORE 8242XS acoustic releases, one set of acoustic release parallel mechanism, Cortland 10mm sheathed Kevlar cable, two Miller 3TC Link swivel rings, stainless steel shackles, stainless steel anchor chains, gravity anchors, etc.

3) The acoustic communication system consists of a pair of Evo Logics S2C acoustic communication machines and one set of underwater battery compartments.
