| contents | Reactive phase Be isotopes, 10Be and 9Be, and major elament measurements were performed on 37 samples from site J1004 hole A. d18O of Neogloboquadrina pachyderma and U. peregrina are measured from the same core for 138 and 143 samples, respectively. The age-depth model for J1004 was published in Riechelson et al., (2023). We follow the method of Sproson et al., (2021) for extracting and measuring reactive Be isotopes in sediments. 10Be/9Be was measured using a National Electrostatic Corporation (NEC) accelerator mass spectrometer (AMS), of 5 MV terminal voltage, at the University of Tokyo (UTokyo), Micro Analysis Laboratory, Tandem accelerator (Matsuzaki et al., 2007). Absolute values were obtained using the KNB5-2 standard (10Be/9Be = 8.558 × 10−12; (Nishiizumi et al., 2007). Decay correction is performed on 10Be concentration using a 10Be half-life of 1.387 Ma. The 10Be/9Be ratios were corrected for 10Be paleo-production using the paleomagnetic reference records of the geomagnetic dipole moment (Korte et al., 2011) following von Blanckenburg et al. (2015). Major elements concentrations were measured by a Rigaku 3270 model X-ray fluorescence (XRF) analysis using glass beads and following the method of Shiroya et al., (2013). Planktonic and benthic foraminifera (Neogloboquadrina pachyderma and U. peregrina, respectively) from the >125 μm size fraction were sonicated in MilliQ water to remove debris prior to analyzing d18O on a Micromass Optima mass spectrometer with a Multiprep device at Rutgers University. |
