Isotopes and Mg/Ca-derived sea-surface temperature records of sediment core MD01-2386


δ18O values (versus Pee Dee belemnite standard) of C. wuellerstorfi (3-10 specimens, >154µm) and G. ruber (white) sensu stricto (8-12 specimens, 250-350µm). The stable isotope composition was measured by Finnigan-MAT253 mass spectrometer equipped with an automatic carbonate preparation device (Kiel III) at the State Key Laboratory of Marine Geology, Tongji University. The isotopic results were calibrated on the Pee Dee Belemnite scale using the China National standard NBS 19. The SD is ±0.07‰. Sample preparation for Mg/Ca measurements on G. ruber samples followed Lea et al. (2000; doi:10.1126/science.289.5485.1719). The Mg/Ca measurements for the upper 400 cm were done using on ICP-MS at the Department of Earth Sciences, University of California, Santa Barbara, the remaining samples were analyzed at the State Key Laboratory of Marine Geology, Tongji University. The Mg/Ca to temperature conversion followed Hollstein et al. (2017; doi:10.1002/2017PA003122). The records cover the last ~142 kyr.
