Abstract: |
Marine biological acoustic scattering layer is widely distributed all over the world. Its diel vertical migration mechanism is closely related to the physical characteristics of the surrounding ocean circulation, and plays an important role in the carbon cycle in the ocean. In this paper, the recent advances in the acoustic scattering layer was reviewed, the research methods and achievements of the diurnal vertical migration of the marine biological acoustic scattering layer in various fields were collected, including the research status domestic and overseas, the acoustic detection methods of the scattering layer, and the global distribution changes. Marine biological acoustic scattering layer is rich in fishery resources. Studying and exploring the scattering layer can help us understand the marine physical environment and the distribution of local marine fishery resources, which is of great significance to the development and utilization of fishery resources. |
