| contents | This data file contains benthic foraminiferal oxygen isotope (δ¹⁸O) and carbon isotope (δ13C) records from ODP Site 807 A. Data from the depth intervals 0.17–8.37 mbsf and 26.27–42.37 mbsf were previously published in Zhang et al. (2007) and Du et al. (2016), respectively. Isotope measurements are based on the >150µm fraction of C. wuellerstorfi where available. If C. wuellerstorfi was not available, specimens of U. peregrina and C. mundulus were used for analysis. All stable isotopic analyses were performed at the State Key Laboratory of Marine Geology, Tongji University on Finnigan MAT 252 or 253 mass spectrometers. External reproducibility based on replicate analyses of benthic foraminiferal samples is 0.07‰ and 0.04‰ for δ18O and δ13C.Various benthic foraminiferal species fractionate oxygen and carbon isotopes differently when forming tests, resulting in offsets in δ18O and δ13C. To account for this, we adopted such conventional correction factors of C. wuellerstorfi and C. mundulus/Uvigerina peregerina that 0.64 ‰ was subtracted from the δ18O and 0.9 ‰ was added to the δ13C of Uvigerina peregerina (Duplessy et al., 1984; Shackleton, 1974). |
