Schmidt, G.A., and S. Mulitza, 2002: Global calibration of ecological models for planktic foraminifera from coretop carbonate oxygen-18. Mar. Micropalaentol., 44, 125-140, doi:10.1016/S0377-8398(01)00041-X.

A global dataset of coretop planktic foraminiferal δ¹⁸O_c is combined with a global database of seawater δ¹⁸O_w observations and ocean climatologies to determine robust optimum parameters for an ecological model for six commonly measured species and varieties. These parameters consist of the temperature ranges, optimum temperatures, depth habitat, and the amount of secondary calcification for G. ruber (white), G. ruber (pink), N. pachyderma (l), N. pacyderma (r), G. sacculifer, and G. bulloides. This approach produces ecological models and temperature ranges consistent with previous work, and manages to reproduce the coretop oxygen-18 carbonate values remarkably well. The standard error of modelled values of coretop calcite globally and for all species is 0.53‰, compared to an error of 1.2‰ when assuming annual average mixed layer equilibrium calcite.
