Observed and Predicted Bulk Sediment Uranium Isotope Composition (δ234U) for ODP 1094 Over the Last 500 kyr

This is supplementary data associated with a manuscript entitled "Anomalous 234U/238U Isotopic Composition in Southern Ocean Sediments" by N. Redmond, C. T. Hayes, S. K. Glasscock, E. Rohde, R. F. Anderson, and D. McGee

Variables
Sample ID - Section of ODP 1094 core. Hole-Core-Section-Depth(cms)
MCD_TOP - Meters Composite Depth at the top of the section
Age (Hasenfratz et al., 19) - in kyrs, based on tuning of benthic δ18O to LR04 stack
U-238 - Concentration of 238U in bulk sediment, units in ppm or micrograms/gram.
aU - Authigenic uranium concentration, calculated from removing th-based detrital U fraction from bulk 238U, units in ppm or micrograms/gram
δ234U Observed - Uranium isotope composition observed in bulk sediment, written as the per mil deviation from secular equilibrium, units in ppm or micrograms/gram
δ234U Observed Error - Uncertainty Uranium isotope composition observed in bulk sediment, written as the per mil deviation from secular equilibrium, units in ppm or micrograms/gram
δ234U Modeled - Uranium isotope composition predicted in bulk sediment by a mixing model of authigenic and detrital U, decayed with age to match observed data, written as the per mil deviation from secular equilibrium, units in ppm or micrograms/gram
δ234U Modeled Error - Uncertainty of Uranium isotope composition predicted in bulk sediment by a mixing model of authigenic and detrital U, decayed with age to match observed data, written as the per mil deviation from secular equilibrium, units in ppm or micrograms/gram
