Three to four years often elapse between publication of the revised Int Cal and Marine curves.Between, publication and ratification of calibration curves new data sets may be added while others, determined to be problematic, are removed.

Our calibration curve has the advantage that each data point has a measured calendar age (230Th/234U/238U) and radiocarbon age with know errors that are independent of each other.

There are sufficient calibration data such that our curve is stable and the primary improvements with future versions will be in the reduction of computed calendar year uncertainties. We appreciate the value of a stable internationally-ratified radiocarbon calibration curve; however, researchers want the best available calibration curve in order to make the most accurate and precise conversion of radiocarbon years to calendar years.

Hence, our expanded data set bolsters our argument that corals demonstrate the greatest potential for providing a “backbone” calibration curve beyond 20,000 years B. Considering the dramatic increase in ocean, climate, and archeological research spanning the past 50,000 years, there is a high and growing demand for radiocarbon calibration.

To avoid a proliferation of calibration curves using outdated versions of our calibration data, we will only offer an on-line version.

To better serve the archeological community, we shall also release the calibration data and access to our curve to Cal Pal at the same time we update our curve.
