Stable water isotopic observations in surface snow over Antarctica provide a foundation for validating isotopic models and interpreting Antarctic ice core records.

The dataset contains a total of 1867 data points, including 1604 locations for oxygen isotope ratio (δ 18 O) and 1278 locations for deuterium isotope ratio (δ 2 H). 1204 locations have both δ 18 O and δ 2 H, from which d-excess (d-excess = δ 2 H − 8 × δ 18 O) can be calculated.
