We will present a method for synchronizing radiocarbon and Greenland ice core time scales back to 16,000 years ago based on Bayesian wiggle matching of cosmogenic radionuclide records.The method utilizes the strength of the high relative precision of ice core time scales as well as the small absolute age uncertainty from tree-ring chronologies and U/Th dated speleothems.This approach can be employed most directly in the case of wood samples with many years growth present (but not able to be dated by dendrochronology), where the tree-ring series of unknown date can be compared against the similarly constructed (super 14) C calibration curve built from known-age wood.This process of curve-fitting has come to be called "wiggle-matching." In this paper, we look at the requirements for getting good precision by this method: sequence length, sampling frequency, and measurement precision.The method has both advantages and limitations vis-a-vis the calibration of individual dates.High-precision chronologies are needed for studies of rapid climate changes.‘@kindle.com’ emails can be delivered even when you are not connected to wi-fi, but note that service fees apply.Find out more about the Kindle Personal Document Service.

Alan Hogg has been involved in dating key New Zealand tephras for many years, by Bayesian methods, including C wiggle matching the archaeologically important Kaharoa (AD 1314 ± 12) and Taupo (AD 232 ± 5) tephras.

We also look at 3 case studies: one a piece of wood which has been independently dendrochronologically dated, and two others of unknown age relating to archaeological activity at Silchester, UK (Roman) and Miletos, Anatolia (relating to the volcanic eruption at Thera).

In some standalone versions the first time you run the Ox Cal program there may be some delay and so the first calibration/view curve operation you do may have to be repeated.
