- (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(δxO + 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’17OVSMOW-SLAP − 0.5278 × δ’18OVSMOW-SLAP + 0.040
