  1. (a)δ-values are expressed as per mil relative to Vienna Standard Mean Ocean Water (VSMOW)
  2. (b)Standard deviation (SD) means an external reproducibility for each analyses
  3. (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
  4. (d)δ-values are obtained from linearized delta values after normalization by the scaling factor
  5. (e)Deviation of 17O/16O ratio of sample is estimated as: Δ’17O = δ’17OVSMOW-SLAP  0.5278 × δ’18OVSMOW-SLAP + 0.040
