📉 研究结果揭示，全球地表水稳定同位素从赤道向两极、从沿海向内陆逐渐贫化。这种变化在不同区域表现出显著差异，反映了水循环的复杂性和多样性。

🌡️ 地理位置、地形条件和气象因素（尤其是温度）是控制地表水同位素变化的关键因素。数据集的分析强调了这些因素对水循环的深刻影响。

💡 该数据集为深入理解水循环和气候变化提供了重要信息，并为全球水资源管理和研究提供了关键数据参考，具有重要的科学和应用价值。

Open-access: Global Stable Isotope Dataset for Surface Water. The dataset consists of three main elements: website data from IEAE (GNIR), water isotope website from University of Utah, measured data and reference data – 22,432 surface water sampling sites across seven continents. Put together by Li et al (2025). Dataset link in the comments.

Abstract
“Hydrogen and oxygen stable isotopes are widely used as tracers of the water cycle, and surface water is an integral part of the water cycle. Compared with other waterbodies, surface water is more susceptible to different natural and anthropogenic factors, and an accurate understanding of surface water changes is of great significance in ensuring regional water security, maintaining ecological balance, and promoting sustainable economic and social development. The spatial and temporal distributions of global surface water stable isotope data are extremely uneven on a global scale due to factors such as observation conditions and instrumental analysis. For this reason, we have compiled and analysed the stable hydrogen and oxygen isotope data in surface water from 22 389 sampling stations worldwide from 1956 to 2023, with 102 511 data records. The results indicate the following: (1) global surface water stable isotopes are gradually depleted from the Equator to the poles and from the coast to the interior. However, there are significant differences in the spatial and temporal distributions of surface water isotopes in different regions. (2) The variation in stable isotopes in surface water is controlled by geographic location, topographic conditions and meteorological factors (especially temperature), and its heterogeneity is considerable. The global stable isotope dataset of surface water provides vital information for an in-depth understanding of the water cycle and climate change. It can provide essential data references for global water resource management and research.”
