C14 Radiocarbon Dating - Sample - SRR?
SRR?
Shell (outer part) from a layer in a shell midden. PROBLEM: As of 2009, the calibration is uncertain because the marine effect varies (Ascough PhD) and it is not safe simply to correct the age by 405 C14 years. CHECK NEEDED to see if d13C value really positive or '-' simply not entered by me.
