A and waterlogged Oaks in Ireland and Germany, and Kauri in New Zealand to provide records extending back over the last 14, years. For older periods we are able to use other records of with idependent age control to tell us about how radiocarbon changed in the past.

The information from measurements on tree rings and other samples of known age including speleothems, marine corals and samples from sedimentary records with independent dating are all compiled into calibration curves by the IntCal group. These are the basis for the calibrations performed by the programs like CALIB and OxCal.

For more detail see the OxCal manual. Calibration of radiocarbon determinations is in principle very simple. If you have a radiocarbon measurement on a sample, you can try to find a tree ring with the same proportion of radiocarbon. Since the calendar age of the tree rings is known, this then tells you the age of your sample. The pair of blue curves show the radiocarbon measurements on the tree rings plus and minus one standard deviation and the red curve on the left indicates the radiocarbon concentration in the sample.

The grey histogram shows possible ages for the sample the higher the histogram the more likely that age is. The results of calibration are often given as an age range. This is not intended to be an exhaustive summary of radiocarbon calibration conventions but a brief guide. The first indicates the proportion of radiocarbon atoms in the sample as compared to samples modern in The second is directly derived from this on the assumption that the half-life of radiocarbon is years and the amount of radiocarbon in the atmosphere has been constant.

Once calibrated a radiocarbon date should be expressed in terms of cal BC, cal AD or cal BP. The cal prefix indicates that the dates are the result of radiocarbon calibration using tree ring data. These values should correspond exactly to normal historical years BC and AD. These are the basis for the calibrations performed by the programs like CALIB and OxCal.

These values should correspond exactly to normal historical years BC and AD. The term cal BP means the number of years before and can be directly compared to calendar years.

This method will tell you the years in which the radiocarbon concentration of tree rings is within two standard deviations of your measurement e.

This requires a computer since the calculations are more complicated.

The OxCal program is intended to provide radiocarbon calibration and analysis of archaeological and environmental chronological information. The current version is 4. It is available for online use or downloading. A variety of different chronological models can be included in the analysis. The information for such analysis can be entered using the user interface or in the form of text command files. This version is available for online use or download.

Please follow the following link to sign on or get a password:. Please see the installation instructions for further details. The IntCal20, SHCal20 and Marine20 data files are bundled with OxCal with the kind permission of the compilers. Full details are given in Radiocarbon IntCal20 special issue. An EMail distribution list is held of people who might be interested in announcements about updates and changes to this program:.

There is also a discussion group for those interested in discussing use of the program, reporting bugs or suggesting improvements members can send mail to this group but not the announcement list :. Previous versions of OxCal are avaliable for download. Note that some of these have different setup requirements. Version was 3.

It has the same functionality as CAL25 but with a new user interface.. New York: Marcel Dekker. Multiple papers have been published both supporting and opposing the criticism. Wikidata Q August The 10MV tandem accelerator ANTARES is a state-of-the-art facility for ion beam analysis and accelerator mass spectrometry. The wood in these rings once laid down remains unchanged during the life of the tree.

This affects the ratio of 14 C to 12 C in the different reservoirs, and hence the radiocarbon ages of samples that originated in each reservoir. BST 12 p.
