Description

technical field

[0001] The invention relates to the field of hydrothermal vent positioning, in particular to a device, method and system for quickly searching and locating deep-sea hydrothermal vents. Background technique

[0002] After the "Alvin" manned submersible first discovered a hydrothermal area in the waters of the Galapagos Islands on the East Pacific Sea Rise in 1977, the submarine hydrothermal area, with its unique high temperature, high pressure, and anoxic environment, is rich in mineral deposits. Resources and unique biological and genetic resources have aroused the astonishment and great interest of scientists. The research on hydrothermal regions has both scientific and economic significance, and the discovery of hydrothermal vents is the basis of the research. Submarine hydrothermal activities are mainly distributed in mid-ocean ridges and back-arc basins, and some are located in volcanic arcs and intraplate volcanoes. Judging from the hydrothermal areas ...
