Description

The presented dataset contains results of stable water isotope composition of water samples collected during 2017-2023 across Kazakhstan with one lake sample from Kyrgyzstan (Issyk-kul Lake). The dataset has the oxygen and hydrogen isotopic ratios (δ2H and δ18O) expressed in per mil (‰) after normalization of raw measurements with international accepted reference standards (i.e VSMOW2 and SLAP2) along with measurements error reported as one standard deviation. The dataset (n=399) consist of following water source types: precipitation (n=130) - event precipitation (n=108), monthly cumulative (n=22); surface water (n=175) – rivers (n=69), brooks (n=19), channels (n=7), lakes (n=78), reservoirs (n=2); groundwater (n=85) - shallow groundwater (n=76), artesian (free-flowing) groundwater (n=8), a spring (n=1); tap water (n=9. The Excel spreadsheet containing data has five tabs: 1) Precipitation events; 2) Precipitation monthly; 3) Surface water; 4) Groundwater; 5) Tap water. The tabs have the following columns: Sample no, Sample ID, Sample type, Sample subtype, Event type (for event precipitation), Sample description, Date, Location, Coordinate 1, (Lat N), Coordinate 2, (Lon E), Comment, Measurement method, δ18O, ‰, 1σ (standard deviation for oxygen), δ2H, ‰, 1σ (standard deviation for hydrogen).
