“…High-frequency sound waves propagate over long distances, and can be used in deep water environments and turbid water bodies. They also have a broad monitoring coverage area, which is conducive to capturing underwater oil droplets [62]. Currently, research has found that the backscattering property of acoustic technology can be well applied to the monitoring of underwater oil spills.…”

“…An echo sounder can identify underwater oil leaks by the changes in acoustic backscattering intensity [59][60][61]. Multibeam sensors have good target classification and recognition functions, and can provide a three-dimensional diffusion map of oil droplets in the water column [62][63][64]. Side-scan sonar can quickly monitor large areas of oil spills through the image of acoustic reflectivity [65,66].…”

“…Active detection refers to the analysis of the movement of oil droplets and gases according to the echoes by emitting sound waves into oil droplets and gases in the deep sea [81]. Active acoustic detection is commonly used for underwater oil droplet and low solubility gas monitoring [60][61][62][63]67,73,82,83]. However, active detection requires higher working power and is suitable for short-time-period monitoring, while deep-sea oil spill monitoring requires a longer working period.…”

Acoustic monitoring is an efficient technique for oil spill detection, and the development of acoustic technology is conducive to achieving real-time monitoring of underwater oil spills, providing data references and guidance for emergency response work. Starting from the research background of oil spills, this review summarizes and evaluates the existing research on acoustic technology for monitoring underwater oil spills. Underwater oil spills are more complex than surface oil spills, and further research is needed to investigate the feasibility of acoustic technology in underwater oil spill monitoring, verify the accuracy of monitoring data, and assess its value. In the future, the impact mechanism and dynamic research of acoustic technology in oil spill monitoring should be explored, and the advantages and differences between acoustic technology and other detection techniques should be compared. The significance of auxiliary mechanisms combined with acoustic technology in oil spill monitoring should be studied. Moreover, acoustic research methods and experimental techniques should be enriched and improved to fully tap into the future value of acoustic technology.
