CCTV News on May 28th, the scientific research ship “Science” of the Institute of Oceanology, Chinese Academy of Sciences, first observed evidence of the existence of gaseous water in the deep sea hydrothermal area. The result was officially published today (May 28) in the authoritative journal of Earth Science, Geophysical Research Letters.
Researchers at the Institute of Oceanography, Chinese Academy of Sciences found an inverted lake formed by a large number of “mushroom-type” hydrothermal chimney structures through the HD camera “Discovery” in the deep sea hydrothermal area . The lake is full of sparkling water. This is due to the strong light reflection layer formed by the huge temperature and density difference. Raman spectroscopy acquisition and temperature measurement of different layers in the water body of the inverted lake were carried out by deep-sea laser Raman spectroscopy in-situ detection system and deep-sea hydrothermal temperature probe. The results show that the water body in the lake is inverted in this area, from the top to the bottom are the high-temperature steam phase, the mixed phase of hydrothermal fluid and seawater, and the normal seawater phase at the bottom. The temperature of the top fluid can reach 383.3 ℃. 
Researcher Zhang Xin, Institute of Oceanology, Chinese Academy of Sciences: < / strong> Gaseous water is water that reaches its vaporization temperature, which is equivalent to the presence of a large bubble on the bottom of the sea, but the reason why this large bubble does not rise upward is that we covered a layer of hot liquid The sulfide mineral, which is equivalent to an inverted bowl, covers this bubble. 
The deep-sea hydrothermal system has bred abundant mineral and genetic resources, It is even considered to be related to the origin of life, and has always attracted the attention of the scientific community. According to experts, gaseous water can remain on the sea floor in the area, thanks to the unique hydrothermal chimney structure in the area. This new discovery helps to reveal such low-density meteorology, the hydrothermal sulfide mineralization process of the hydrothermal eruption system, and its impact on the deep-sea environment.
