Radiocarbon dating calibration methods carbon dating of genesis
Details Calibration of a radiocarbon age of 6550 ± 40 BP of a terrestrial sample from the Northern Hemisphere, using Int Cal04 calibration curve and Ox Cal program version 3.10.
In 2002, Caitlin Buck was recruited to the IWG and asked to offer advice on statistical methods for curve construction.
Win Cal25 is a Windows remake of the CAL25 DOS program. Users can view and make maps and compute estimates for the Marine Radiocarbon Reservoir Age of the surface ocean based on model and measured radiocarbon reservoir age estimates.
It has the same functionality as CAL25 but with a new user interface.. As described in: "Marine Radiocarbon Calibration Curve Spanning 0 to 50,000 Years B. Based on Paired 230Th/234U/238U and 14C Dates on Pristine Corals," by Richard G. Mortlock, Tzu-Chien Chiu, Li Cao, Alexey Kaplan, Thomas P. The program operates on the Google Earth and Google Map application engines and features overlay data sets particularly useful for interpreting the radiocarbon reservoir age estimates. Southeast Asia and Anatolia 14Sea Project: 14C database of Anatolia, the Aegean, and southeast Europe available in downloadable Excel files.
Details C concentrations are mainly due to variations in the rate of radiocarbon production in the atmosphere, caused by changes in the Earth's magnetic field and variability in solar activity, and changes in the carbon cycle.
The result is that radiocarbon and calendar ages are not identical, and the radiocarbon ages have to be converted to calendar ages using a calibration curve, which describes the atmospheric C concentration in the past measured in precisely and independently dated materials.
