Details on the Method
Calculating ΔR from a marine sample whose year of collection is known
involves 2 steps:
- Intersect the calendar year of collection with the marine calibration
curve and determine the corresponding 14C age (reverse-calibrate).
- Subtract the reverse-calibrated collection year from the mean of the
14C age of the marine sample
The uncertainty of ΔR is the uncertainty of the marine sample 14
