The influence of seawater carbonate ion concentration [CO32−] on the stable carbon isotope composition of the planktic foraminifera species Globorotalia inflata
I Wilke, T Bickert, FJC Peeters - Marine Micropaleontology, 2006 - Elsevier
We sampled the upper water column for living planktic foraminifera along the SW-African
continental margin. The species Globorotalia inflata strongly dominates the foraminiferal
assemblages with an overall relative abundance of 70–90%. The shell δ18O and δ13C
values of G. inflata were measured and compared to the predicted oxygen isotope
equilibrium values (δ18Oeq) and to the carbon isotope composition of the total dissolved
inorganic carbon (δ13CDIC) of seawater. The δ18O of G. inflata reflects the general gradient …
