Abstract:

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 situation 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 systems, 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.

Key words: sea ice thickness, satellite altimeter, ship-based monitoring, eletromagnetic induction sounding, research progress
