{"id":"https://openalex.org/T10398","display_name":"Groundwater and Isotope Geochemistry","description":"This cluster of papers focuses on the stable isotopic analysis of groundwater and precipitation, including the use of isotopes to study nitrate contamination, groundwater recharge, climate change impacts, and water quality. It also addresses global depletion of groundwater resources and hydrogeochemical processes influencing groundwater composition.","keywords":[{"id":"https://openalex.org/keywords/stable-isotopes","display_name":"stable isotopes","score":0.2195},{"id":"https://openalex.org/keywords/groundwater-hydrochemistry","display_name":"hydrogeochemistry","score":0.4284},{"id":"https://openalex.org/keywords/oxygen-18","display_name":"oxygen-18","score":0.4102},{"id":"https://openalex.org/keywords/water-rock-interaction","display_name":"water-rock interaction","score":0.3275},{"id":"https://openalex.org/keywords/groundwater-age","display_name":"groundwater age","score":0.8041},{"id":"https://openalex.org/keywords/stable-water-isotopes","display_name":"stable water isotopes","score":0.4411},{"id":"https://openalex.org/keywords/isotope-hydrology","display_name":"isotope hydrology","score":0.7964},{"id":"https://openalex.org/keywords/submarine-groundwater-discharge","display_name":"submarine groundwater discharge","score":0.4792},{"id":"https://openalex.org/keywords/groundwater-mixing","display_name":"groundwater mixing","score":0.6814},{"id":"https://openalex.org/keywords/deuterium-excess","display_name":"deuterium excess","score":0.6128},{"id":"https://openalex.org/keywords/groundwater-residence-time","display_name":"groundwater residence time","score":0.6664},{"id":"https://openalex.org/keywords/groundwater-salinization","display_name":"groundwater salinization","score":0.3277},{"id":"https://openalex.org/keywords/meteoric-water","display_name":"meteoric water","score":0.2203},{"id":"https://openalex.org/keywords/silicate-weathering","display_name":"silicate weathering","score":0.2634},{"id":"https://openalex.org/keywords/delta18o","display_name":"\u03b418O","score":0.2495},{"id":"https://openalex.org/keywords/shallow-groundwater","display_name":"shallow groundwater","score":0.2099},{"id":"https://openalex.org/keywords/precipitation-isotopes","display_name":"precipitation isotopes","score":0.5998},{"id":"https://openalex.org/keywords/hydrogen-and-oxygen-isotopes","display_name":"hydrogen and oxygen isotopes","score":0.4552},{"id":"https://openalex.org/keywords/groundwater-dating","display_name":"groundwater dating","score":0.8563},{"id":"https://openalex.org/keywords/environmental-isotopes","display_name":"environmental isotopes","score":0.7698},{"id":"https://openalex.org/keywords/evaporite-dissolution","display_name":"evaporite dissolution","score":0.4086},{"id":"https://openalex.org/keywords/geothermal-fluids","display_name":"geothermal fluids","score":0.2024},{"id":"https://openalex.org/keywords/groundwater-flow-paths","display_name":"groundwater flow paths","score":0.3437},{"id":"https://openalex.org/keywords/geothermal-water","display_name":"geothermal water","score":0.2441},{"id":"https://openalex.org/keywords/groundwater-origin","display_name":"groundwater origin","score":0.7825}],"legacy_keywords":"Groundwater; Isotopes; Stable; Precipitation; Nitrate; Recharge; Climate Change; Water Quality; Hydrogeochemical Processes; Global Depletion","ids":{"openalex":"https://openalex.org/T10398","wikipedia":"https://en.wikipedia.org/wiki/Groundwater_isotope_hydrology"},"subfield":{"id":"https://openalex.org/subfields/1906","display_name":"Geochemistry and Petrology"},"field":{"id":"https://openalex.org/fields/19","display_name":"Earth and Planetary Sciences"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"},"siblings":[{"id":"https://openalex.org/T11740","display_name":"Geochemistry and Elemental Analysis"},{"id":"https://openalex.org/T12218","display_name":"Coal and Its By-products"},{"id":"https://openalex.org/T13067","display_name":"Geological Modeling and Analysis"},{"id":"https://openalex.org/T13209","display_name":"Cold Fusion and Nuclear Reactions"},{"id":"https://openalex.org/T13443","display_name":"Mineralogy and Gemology Studies"}],"works_count":77593,"cited_by_count":1141541,"works_api_url":"https://api.openalex.org/works?filter=topics.id:T10398","updated_date":"2026-10-22T03:01:35","created_date":"2024-01-23T15:27:06"}
