Long-term ice phenology records for 78 lakes in the Northern Hemisphere

Lake ice is an important resource supporting water quality, local biodiversity, arctic transportation, and regional economies. Long-term surveys of lake ice collected in situ are the gold standard for monitoring in environmental science., Here, we present ice phenology records for 78 lakes in the Northern Hemisphere spanning up to 578 years. These surveys include 12 different countries across North America and Eurasia collected by researchers, community scientists, priests, and digital observations. This database includes information about ice phenology (ice-on dates, ice-off dates, ice cover duration), lake characteristics (e.g., size, location, names), and meta-data about each data source (e.g., how the data was collected). Our intention is that this database may be used to understand factors driving lake ice patterns and the biological or socio-economic consequences.

湖冰是支撑水质维持、本土生物多样性保护、北极交通以及区域经济发展的重要自然资源。长期原位采集的湖冰调查数据是环境科学监测领域的金标准。本研究提供了北半球78座湖泊的冰物候（ice phenology）记录，观测时长最长可达578年。这些调查数据覆盖北美与欧亚大陆的12个国家，数据来源包括科研人员、社区科学工作者、神职人员的实地观测以及数字化观测记录。本数据库涵盖冰物候相关信息（封冻日期、融冻日期、冰盖持续时长）、湖泊基本属性（如面积、地理位置、名称），以及各数据源的元数据（如数据采集方式）。本数据库旨在助力研究人员解析驱动湖冰变化模式的关键因素，以及其带来的生态与社会经济影响。
