CALIB Home Page.It is one of several similarly formed cosmogenic nuclides.Newly formed carbon-14 atoms oxidize to carbon dioxide and become thoroughly mixed with the other atmospheric gases, through atmospheric dynamics.The package also allows Bayesian analysis of sequences, phases, tree-ring sequences, age-depth models, etc. BCal: Online Bayesian radiocarbon calibration tool. Developed at the Department of Probability & Statistics, University of Sheffield (UK), this allows users to obtain calibrated dates on data sets entered via a Web browser.Cal Pal: Cologne Radiocarbon CALibration and PALaeoclimate Package.

The radiocarbon dating method is based on the fact that plant and animal tissue levels of carbon-14 remain relatively constant during life, but taper off at a predictable rate in surviving remains. Typically, traces of radiocarbon can be detected in organic remains up to 50,000 years old.
