Calibration of the carbon isotope composition (C-13) of benthic foraminifera
The carbon isotope composition (C-13) of seawater provides valuable insight on ocean circulation, air-sea exchange, the biological pump, and the global carbon cycle and is reflected by the C-13 of foraminifera tests. Here more than 1700 C-13 observations of the benthic foraminifera genus Cibicides f...

The carbon isotope composition (C-13) of seawater provides valuable insight on ocean circulation, air-sea exchange, the biological pump, and the global carbon cycle and is reflected by the C-13 of foraminifera tests. Here more than 1700 C-13 observations of the benthic foraminifera genus Cibicides from late Holocene sediments (C-13(Cibnat)) are compiled and compared with newly updated estimates of the natural (preindustrial) water column C-13 of dissolved inorganic carbon (C-13(DICnat)) as part of the international Ocean Circulation and Carbon Cycling (OC3) project. Using selection criteria based on the spatial distance between samples, we find high correlation between C-13(Cibnat) and C-13(DICnat), confirming earlier work. Regression analyses indicate significant carbonate ion (-2.60.4)x10(-3)/(molkg(-1)) [CO32-] and pressure (-4.91.7)x10(-5)m(-1) (depth) effects, which we use to propose a new global calibration for predicting C-13(DICnat) from C-13(Cibnat). This calibration is shown to remove some systematic regional biases and decrease errors compared with the one-to-one relationship (C-13(DICnat)=C-13(Cibnat)).
