Table 1.

Interquartile ranges (IQR 25–75%) for measured δ¹⁸O and δ²H (in ‰,VSMOW) values, and for the derived LMWL intersections (δ¹⁸O_LMWLi and δ²H_LMWLi), given for all sample types in both plots (sandy and clayey plots). Precip contains both measured bulk precipitation as through-fall. Different letters per column represent statistical differences (non-parametric Kruskal–Wallis test with Dunn post hoc analysis, P < 0.05) between sample types with χ² being the chi-squared value.
