^(a)δ-values are expressed as per mil relative to Vienna Standard Mean Ocean Water (VSMOW)
^(b)Standard deviation (SD) means an external reproducibility for each analyses
^(c)Delta prime (δ’) is defined as 10³ × ln(δ^xO + 1) by Miller (2002). The VSMOW-SLAP scaling factor (1.019) is applied to linearized delta prime values
^(d)δ-values are obtained from linearized delta values after normalization by the scaling factor
^(e)Deviation of ¹⁷O/¹⁶O ratio of sample is estimated as: Δ’¹⁷O = δ’¹⁷O_VSMOW-SLAP − 0.5278 × δ’¹⁸O_VSMOW-SLAP + 0.040
