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.
