Planktic foraminifera oxygen isotope ratios and Mg/Ca ratios and associated calcification temperature of sediment core 3cBx


Multi-species planktonic foraminifera oxygen isotope ratios (measured on a Finnigan MAT 253) and Mg/Ca ratios (measured on a Perkin Elmer Optima 4200DV ICP-AES) and associated calcification temperature estimates for core 3cBx. Measurements were done on approximately 40 specimens in the 355-425 micrometer fraction. Cleaning for Mg/Ca was done using both oxidative and reductive steps. Radiocarbon ages measured on the planktonic foraminifera (Trilobatus sacculifer) are included to reproduce and update the age-depth model of the core.
