持续变化的北极环境及极地声学研究新进展

Recent advances in polar acoustics research in the continually changing Arctic

  • 摘要: 在全球变暖的大趋势下, 北极海域气候环境和海洋环境持续变化, 主要表现为海冰体量逐渐变少、夏季开阔海域面积逐渐扩大、多年冰持续减少、冰边缘区水文分层更加复杂等。在其影响下, 北极海域水声环境也在发生持续的变化。论文从新时期北极海域的海冰、水文和海底等波导环境特性出发, 综述了北极海域声传播特性、冰下噪声特性、冰区混响特性等方面的最新研究成果; 并结合国内外开展的北极声学观测试验, 重点介绍了水声环境效应综合观测、冰下水声通信导航以及冰层形态声学监测等方面的进展。最后对北极水声学研究进行了总结, 并展望了未来发展趋势。

     

    Abstract: Under the general trend of global warming, the climate and marine environment of the Arctic seas are changing persistently, which are manifestations of gradual decrease in the volume of sea ice, the gradual expansion of the open sea area in summer, the continuous reduction of multi-year ice. The hydrological stratification in the ice edge zone has become more complex. Under the influence of the phenomenon in oceanographical variabilities, the underwater acoustic environment in Arctic is also undergoing persistently changes. Starting from the characteristics of waveguide environments such as sea ice, hydrology, and seafloor in the new epoch Arctic seas, this article summarizes the latest research progress of the acoustic propagation characteristics, under-ice noise characteristics, and under-ice reverberation characteristics of the Arctic. Combining the domestic and foreign research progress of the Arctic acoustic observation experiments, special emphases are given on the comprehensive environmental observation of underwater acoustics, under-ice acoustic communication and navigation, and ice morphology acoustic monitoring. Finally, the research of the Arctic underwater acoustics is summarized and the future development trends are predicted.
