OxCal - University of Oxford In April 2014 I published a guest article about statistical methods applicable to radiocarbon dating, which criticised existing Bayesian approaches to the problem. The OxCal program is intended to provide radiocarbon calibration and analysis of archaeological and environmental chronological information. The current version is 4.3 and works with IntCal13. It is available for online use or downloading.
Radiocarbon calibration - Wikipedia A standard – subjective Bayesian – method of inference about the true calendar age of a single artefact from a radiocarbon date determination (measurement) involved using a uniform-in-calendar-age prior. Radiocarbon dating measurements produce ages in "radiocarbon years", which must be converted to calendar ages by a process called calibration. Calibration is needed because the atmospheric 14 C / 12 C ratio, which is a key element in calculating radiocarbon ages, has not been constant historically.
ORAU - Oxford Radiocarbon Accelerator Unit I argued that this did not, as claimed, equate to not including anything but the radiocarbon dating information, and was not a scientifically sound method for inference about isolated examples of artefacts. My article attracted many comments, not all agreeing with my arguments. OxCal; The Oxford Radiocarbon Accelerator Unit ORAU is a radiocarbon laboratory engaged in collaborative research across many disciplines where the measurement of.
Interpreting Radiocarbon Dates SpringerLink This article follows up and expands on points in my original article, and discusses objections raised. Radiocarbon dating involves determining the radiocarbon age of (a sample from) an artefact and then converting that determination to an estimate of the true calendar age , using a highly nonlinear calibration curve. Summary. Radiocarbon dating has become the premiere method for dating organic remains of the last 50,000 years, and sophisticated calibration by reference to tree-ring sequences allows us to convert radiocarbon years into calendar years for samples less than 24,000 years old.
