Hydrothermal plume is an important symbol of hydrothermal activity. Seafloor polymetallic sulfide deposits are products of hydrothermal activity. At the present stage, seafloor polymetallic sulfide prospection and exploration in the mid-ocean ridges are mainly based on the detection of hydrothermal plume and combined with the comprehensive anomaly detection information to realize the breakthrough from the discovery of hydrothermal vents to the discovery of mineral deposits. Based on the hydrothermal plume as the research object, from the three aspects of near-bottom observations, dispersion mechanism and distribution characteristics, this paper summarizes the latest progress and aspects need to be improved of hydrothermal plume, and emphasizes the hydrothermal mapping as a prospective tool for seafloor polymetallic sulfide deposits in the mid-ocean ridges. Finally, this paper points out in conclusion that the spatial and temporal continuity, parameter diversification will be the development trend of hydrothermal detection, which will help promote understanding of hydrothermal plume distribution characteristics and will provide more detailed data to the study on the model of the hydrothermal fields.
