Chinese (researcher) have deployed an in-situ scientific experiment station on the seabed that will enable long-term unscrewed scientific research in the deep sea. The in-situ scientific experiment station is a new deep-sea system (suggest) by China in recent years. Usually, (tradition) marine surveys take samples from the seabed and get hem tested in the land labs. For in-situ testing in the deep sea, damage or loss of sample data due to environmental changes can (avoid).
