The analytical reproducibility based on pooled standard # deviations of duplicate measurements of samples is =< 0.01 units for the MBT # index and ~0.01 units for the CBT ratio, or ~0.02 pH units and ~0.2C in the temperature # estimates. # # Variables: # depth Depth (cm) # yrBP radiocarbon years B.P.
