Comment:
Notes: Uncertainties of concentrations include all weighing errors; isotope ratios are independent of weighing uncertainties. All isotope ratios are expressed as acivities and are calculated using the decay constants of Cheng et al. (2000), Holden (1990), and Jaffey et al. (1971). Depth = top of sample interval
