Comment:
Weight correction factor (Sigma f) corrects the species-depending fractionation factors ranging from +1.6‰ to -2.5‰ for different coccolithophore species. Sigma f = (-1.2a-1.6b+2.5c+2.5d+2.2e-1.6g)/100, with a b c d e g represents estimates of the weigth percent of species. a = gephyrocapsids, b = Emiliana huxleyi, c = Calcidiscus leptoporus, d = Umbilicosphaera sp., e = Syracosphaera sp., g = Pseudoemiliana lacunosa. Vital effect adjustment is calculated from raw delta18O data (Nelsen et al., 1986, doi:10.1594/PANGAEA.683884): d18O(vea) = d18O(raw) + Sigma f
