Progress and Development Trend of Global Refined Seafloor Topography Modeling

  • 摘要: 精细的海底地形模型在海底板块构造运动、水下载体航行保障、海洋资源勘探等方面具有重要作用。回顾国内外海底地形探测技术和模型构建的发展,讨论当前全球海底地形精细建模的研究现状和面临的主要挑战,总结今后全球海底地形精细建模的发展趋势,认为基于卫星测高技术的海洋重力场反演仍是未来全球海底地形精细建模的主要技术手段,并且新体制测高卫星如双星跟飞测高和SWOT(surface water ocean topography)二维海面高测量任务将为进一步提升海洋重力场以及海底地形模型精度提供数据源,结合地形复杂度优化海底地形反演理论方法有望带来理论创新,探索人工智能技术用于海底地形精细建模值得关注。

     

    Abstract: The refined seafloor topography models play an important role in fields of submarine plate tectonic movement, underwater carrier navigation support and marine resource exploration and so on. This paper reviews the development of seafloor topography detection technology and model construction, and discusses the current research status and main challenges of the global refined seafloor topography modeling. Also, the developing trends of global seafloor topography modeling are summarized, considering that the technology of recovering seafloor topography from altimeter-derived marine gravity anomalies is still the main way to construct global seafloor topography models. New altimeter satellites such as dual satellite tandem altimeter and surface water ocean topography will provide data sources for further improving the accuracy of marine gravity field and seafloor topography models. Optimization of seafloor topographic inversion theory based on topographic complexity is expected to bring theoretical innovation. It is worth paying attention to explore the application of artificial intelligence technology in global seafloor topography modeling.
