Carbon stable isotopes (δ13C) in modern sea water samples and planktic foraminifera Globigerina bulloides from core top and down core sediments are used to estimate the distribution of δ13C of dissolved inorganic carbon (DIC) in the surface waters of the southwest Pacific in the modern, pre‐industrial (PI) and over the last 25 kyr. The predicted δ13C distribution in the modern (δ13CDIC), PI (δ13CPI) and late Holocene (from planktic foraminifera Globigerina bulloides (temperature corrected ‐ δ13CG.bulloidesTC) from core tops) display a broad peak at the Subtropical Front (STF) and subantarctic surface waters (SASW) due to the combination of high biological productivity and thermodynamic air‐sea gas exchange of CO2 in this region. The estimated δ13CPI values... |
