Win Cal25 is a Windows remake of the CAL25 DOS program. United Kingdom Archaeological site index to radiocarbon dates from Great Britain and Ireland: database of over 4000 dates from the British Isles. Search access via the Archaeology Data Service catalogue.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. Oxford Radicarbon Accelerator Unit (ORAU) Datelist Index.
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.
During this time the C level intermediate between these two reservoirs.
Marine samples living in the surface ocean (e.g., shells, corals and planktonic foraminifera), therefore appear older than contemporaneous terrestrial samples.

For a radiocarbon value measured in a sample S (Fs), bomb radiocarbon delivers two possible calendar dates (T1 and T2), indicated by the grey boxes (Hua, 2009).
