Abstract

The invention relates to a fast search and positioning device, method and system for deep-sea hydrothermal vents. The device includes: a receiving hydrophone array, a beam scanning unit, a hydrothermal vent detection unit and a hydrothermal vent directional positioning unit, the receiving hydrophone array is used to collect underwater acoustic data, and the beam scanning unit detects the hydrothermal Acoustic data is processed to obtain an acoustic signal, and the hydrothermal vent detection unit is used to judge whether there is a hydrothermal vent according to the acoustic signal, and the directional positioning unit for the hydrothermal vent is used to locate the hydrothermal vent when the hydrothermal vent exists. Location of hydrothermal vents. The invention can realize long-distance rapid search and precise positioning of deep-sea hydrothermal vents.

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 ...
