reporter learned from of the Chinese Academy of Sciences on the 28th that the "Exploration 2" scientific research ship carried "Deep Sea Warrior" manned submersible and completed a series of sea trial tasks and has returned to Sanya a few days ago. During the sea trial, scientific researchers successfully set up large-depth in-situ scientific experimental stations on the seabed, which will achieve long-term unmanned scientific research in the deep sea.

In-situ Scientific Experiment Station is a new deep-sea equipment technical system proposed by my country in recent years. It takes the deep-sea/absolute base station as the core, can carry a variety of unmanned submersibles, and can be connected to platforms such as chemistry/biology laboratories to carry out a series of scientific exploration and scientific experiments in the deep-sea/absolute in situ.
"The layout of an in-situ scientific experimental station on the seabed is equivalent to moving the testing and analysis instruments of the land laboratory to the seabed as a whole." Associate researcher Chen Jun, an associate researcher at the Institute of Deep Sea Science and Engineering of the Chinese Academy of Sciences, introduced that compared with the traditional ocean survey method of obtaining land laboratory testing after sampling from the seabed, conducting scientific experiments in the deep sea can avoid damage or missing sample data caused by environmental changes.

According to reports, the in-situ scientific experimental station system set up this time will work independently on the seabed, and can conduct its own status monitoring and intelligent management. All data will be regularly transmitted back to the shore-based control center through the deep-sea glider relay communication, and scientific researchers can also remotely control the in-situ scientific experimental station.
The in-situ scientific experimental station deployed this time is equipped with a megawatt-hour lithium battery energy system, achieving a new breakthrough in energy density. The energy system can store 1,000 kWh of electricity, supporting in-situ scientific experiments to work on the seabed for more than half a year.

This sea trial was conducted to connect the submarine base station to the in-situ laboratory through the "Deep Sea Warrior" manned submersible, and verified the base station's submarine navigation capability and autonomous site movement function, the in-situ laboratory's autonomous operation mode switching function, and the inductively coupled wireless communication function. Following
, the in-situ scientific experimental station will also be connected to more intelligent unmanned experiments, detection and information transmission systems to achieve long-term unmanned scientific research in the deep sea.
