Comment:
Laboratory code/label: IUPH: Institute for Environmental Physics, University of Heidelberg, Germany.
delta234/238U, measured: Measured 234U/238U activity ratios (d234Um) are presented as deviation in permil from the equilibrium value.
delta234/238U, initial: Decay corrected 234U/238U activity ratios (d234Ui) are calculated from the given ages; decay constants by Cheng et al. (2013) (URI: https://doi.org/10.1016/j.epsl.2013.04.006).
Cold-water coral ages, isotope concentration and ratios. U-series datings were obtained from Lophelia pertusa or Madrepora oculata.
