- Aniqlik: Picarro — δ¹⁸O uchun < 0,05‰, δ²H uchun < 0,3‰; LGR — δ¹⁸O uchun ≤ ±0,2‰, δ²H uchun ±0,8‰.
Annotatsiya
This work presents the dataset of stable water isotopes of oxygen and hydrogen measured in water samples from different sources (precipitation, surface water, groundwater, tap water) across Kazakhstan from 2017 to 2018 and from 2020 to 2023. The dataset includes results on isotopic composition of 399 water samples, namely precipitation: event-based (n = 108), cumulative monthly (n = 22); surface water: lakes, reservoirs, brooks, rivers, channels (n = 175), groundwater: shallow and artesian groundwater, spring (n = 85), tapwater (n = 9). For each sample name of the source, location, latitude, longitude and date of sampling, measurement uncertainty (one standard deviation) are available. The samples were assessed by plotting the data in dual δ18O vs. δ2H isotope space with reference to values found in the published literature and fitting a linear regression equation for Astana (event) precipitation. Overall, this is the first dataset covering wide range of sources across Kazakhstan, which could be used by global and regional water resource assessments and studies such as tracing water sources, hydrograph separation and end-member analyses, isotope mass balance, evapotranspiration partitioning, residence time analysis and groundwater recharge.

Sodda qilib aytganda
To‘plamda 2017–2018 va 2020–2023-yillarda Qozog‘iston bo‘ylab olingan 399 ta suv namunasidagi kislorod va vodorod barqaror izotoplari nisbatlari jamlangan: 130 ta yog‘in namunasi (108 tasi alohida yog‘in hodisalaridan, 22 tasi oylik), daryo, soy, kanal, ko‘l va suv omborlaridan 175 ta yer usti suvi namunasi, 85 ta yer osti suvi va 9 ta vodoprovod suvi namunasi. Yer osti suvlari orasida 76 tasi sayoz (bosimsiz) suvlar, 8 tasi o‘zi oqib chiqadigan artezian quduqlaridan va bittasi buloqdan.
Har bir namuna uchun manba, joy, koordinatalar, sana va o‘lchov xatosi ko‘rsatilgan. 2017–2018-yillar namunalari Potsdamdagi Germaniya Yer haqidagi fanlar tadqiqot markazida (GFZ), 2020–2023-yillar namunalari Nazarboyev universitetida tahlil qilingan. Yer usti suvlari orasida Balxash, Kichik Orol va Issiqko‘l kabi yirik oqmas ko‘llar, Orol dengizi havzasidagi Kambash ko‘li hamda Sirdaryo, Nura, Esil va Ertis daryolari bor. Ostonadagi alohida yog‘in hodisalari asosida mahalliy meteor suvlar chizig‘i chiqarilgan.
Mualliflar uni butun mamlakatni qamrab olgan shu turdagi birinchi to‘plam deb ataydi; u suv manbalarini aniqlash, izotop balansi, suvning qatlamda turish vaqtini baholash va yer osti suvlarining to‘yinishini o‘rganishga mo‘ljallangan. Ma’lumotlar Mendeley Data’da e’lon qilingan.
