摘要
海冰是全球气候变化的敏感指示器,对全球热平衡、大气环流、海洋水循环和温盐平衡起到至关重要的作用。海冰厚度作为海冰中最重要的参数之一,也是最难探测的地球物理参数。在回顾和分析基于仰视声纳、走航观测、电磁感应、微波遥感等方法进行极地海冰厚度探测和应用研究的基础上,着重阐述近年来利用卫星测高技术估算极地海冰厚度的研究现状与趋势,为我国开展相关科研工作提供参考。
Sea ice thickness is an important parameter and indicator of climate change that influences the sea ice mass balance, interaction between the ocean and atmosphere, and ocean circulation. This paper reviewed the current sit- uation and progress regarding the detection of polar sea ice thickness using different technologies. The operating principles, advantages, disadvantages, and research status of upward looking sonar, ship-based monitoring sys- tems, electromagnetic induction sounding, microwave remote sensing, and satellite altimetry were summarized. These technologies can provide the basis for improved research on polar sea ice thickness in the future.
