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.
These samples usually undergo acid/base/acid pretreatment (AAA) prior to graphitization.
Acid/base concentrations, temperatures, and times are sample specific.
AMS, on the other hand, can in principle detect a much higher proportion (typically about 1% of the total) allowing sample sizes to be smaller by a factor of about a thousand.
The method is relatively new because it needs very complicated instruments first developed for Nuclear Physics research in the late 20th century.
The listowner reserves the right to implement moderation if that charter stipulation is ignored.Sediments can undergo various pretretments depending on what type of sediment it is.Depending on what the client requests, bulk organics, humic acids, and/or carbonates from a sediment can be pretreated and analyzed.The program can be used for calibration of dates using the Int Cal curves or post-bomb data.Comparisons can also be made to any user-supplied data-set.
