Global Stable Isotope Dataset for Surface Water

The Dataset consists of three main elements: website data (GNIR data, http://nucleus.iaea.org/wiser/explore, water isotopes website, http://wateriso.utah.edu/waterisotopes), measured data and references data. The dataset encompasses 22389 surface water sampling sites across seven continents. Since 2015, an ecohydrological observation system has been implemented in the Shiyang River Basin in the arid zone of Northwest China to systematically gather surface water stable isotope data, serving as the primary source of measured data. The improvements in isotopic data v1.1 are mainly to remove some duplicates and incorrect data.

本数据集包含三大核心组成部分：网站数据（含GNIR数据、访问链接http://nucleus.iaea.org/wiser/explore，以及水同位素网站http://wateriso.utah.edu/waterisotopes）、实测数据与参考文献数据。该数据集覆盖全球七大洲共计22389个地表水采样点位。自2015年起，中国西北干旱区石羊河流域已搭建生态水文观测系统，系统性采集地表水稳定同位素数据，该数据为本数据集实测数据的主要来源。v1.1版本的同位素数据改进主要为移除部分重复数据与错误数据。
