全球冰湖测深统计数据

该数据集收集了全球公布的冰湖测深数据，包括青藏高原及周边地区，加拿大和美国西部，南美安第斯山等地区。记录的重要属性包括冰湖名称、位置、类型、测深年份、对应面积、体积、最大水深和文献来源。冰湖分类按照冰湖之间的拓扑关系进行分类，分别是冰川末端接触湖，冰川末端非接触湖，冰川槽谷湖，冰面湖，冰川阻塞湖。完善的冰湖测深统计工作是拟合冰湖体积-面积经验公式的基础，对于开展冰湖水量评估，开放冰湖水深分布模型至关重要。This dataset compiles globally published glacial lake bathymetric data, covering regions including the Tibetan Plateau and its surrounding areas, western Canada and the United States, the Andes Mountains in South America, and other global regions. Key recorded attributes include glacial lake name, geographic location, type, bathymetric survey year, corresponding surface area, volume, maximum water depth, and literature source. Glacial lakes are classified based on their topological interrelationships, and are divided into five categories: glacier-terminally contact lakes, glacier-terminally non-contact lakes, glacial trough lakes, supraglacial lakes, and glacial-dammed lakes. Comprehensive glacial lake bathymetric statistics serve as the foundation for fitting empirical volume-area formulas of glacial lakes, and are critical for conducting glacial lake water volume assessments and developing glacial lake water depth distribution models.
