Comment:
Flux fusion measurements of elemental concentrations were used to calibrate the scanning X-ray fluorescence (XRF) Fe-count data from EW37JPC. Elemental intensities from EW37JPC were measured using an XRF core scanner (ITRAX, Cox Ltd., Sweden) at LDEO at 2-mm resolution, using an integration time of 10s and a molybdenum x-ray source set to 30 kV and 50 mA. The intensities were calibrated with flux fusion concentration measurements from EW37JPC. Sediment samples spanning the range of XRF intensities were randomized, interspersed with standard reference materials (e.g., JLS-1, JDO-1, SCO-1, AGV-2, DTS-2b, W-2a), ashed, digested in HF and HNO3 overnight, and diluted for analysis on an Agilent 720 Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) at LDEO. The ICP-OES data provide a robust calibration (R2=0.80 for Ca, R2=0.90 for Sr) for the high-resolution XRF records. We calculated Fe flux by multiplying the bulk sediment mass flux record (Zhou et al., 2021, DOI: 10.1016/j.epsl.2021.116910) by the calibrated Fe-concentration data.
