Here table S20
Table S20. XRF-based weight % carbonate (calc. wt % CaCO3) and CaCO3 mass accumulation rates for IODP Site U1403. XRF counts of Ca ) were linearly correlated to mass
spectrometry inferred measurements of weight % carbonate (from Table S12) and discrete shipboard measurements (Norris et al. 2014). This correlation was used to calculate
the 'calc. wt % CaCO3' shown below for all XRF measurements of Ca. This calculated wt % carbonate was used in combination with linear sedimentation rates and linearly
interpolated dry bulk density measurements (interpolated from shipboard measurements in Norris et al. 2014) to calculate the carbonate mass accumulation rates below.
