“…This modeling approach is widely used in Europe and the Near East to improve and refine regional cultural chronologies (Bayliss et al, 1999, Bronk Ramsey et al, 2010Colledge and Conolly, 2010), using legacy 14 C dates to construct chronological models that are then refined with complimentary higher precision AMS 14 C dates. Archaeologists working in the Americas are also starting to use the approach in productive ways (Culleton et al, 2012; Inomata et al, 2013;Jazwa et al, 2013;Kennett et al, 2011Kennett et al, , 2013a.…”

“…Although wiggle matching can be performed visually, quantification of the relationship improves the confidence of the calibration procedure. Wiggle matching has been achieved using classical statistical techniques (Pearson, 1986;Vogel et al, 2001) or, more recently, a probabilistic approach (Bayliss et al, 1999, Bronk Ramsey et al, 2001Slusarenko et al, 2001).…”

The dating of dipterocarp tree rings: establishing a record of carbon cycling and climatic change in the tropics.ABSTRACT: In a first step to obtain a proxy record of past climatic events (including the El Niñ oSouthern Oscillation) in the normally aseasonal tropical environment of Sabah, a radial segment from a recently fallen dipterocarp (Shorea superba) was radiocarbon dated and subjected to carbon isotope analysis. The high-precision radiocarbon results fell into the ambiguous modern plateau where several calibrated dates can exist for each sample. Dating was achieved by wiggle matching using a Bayesian approach to calibration. Using the defined growth characteristics of Shorea superba, probability density distributions were calculated and improbable dates rejected. It was found that the tree most likely started growing around AD 1660-1685. A total of 173 apparent growth increments were measured and, therefore, it could be determined that the tree formed one ring approximately every two years. Stable carbon isotope values were obtained from resin-extracted wholewood from each ring. Carbon cycling is evident in the 'juvenile effect', resulting from the assimilation of respired carbon dioxide and lower light levels below the canopy, and in the 'anthropogenic effect' caused by increased industrial activity in the late-nineteenth and twentieth centuries. This study demonstrates that palaeoenvironmental information can be obtained from trees growing in aseasonal environments, where climatic conditions prevent the formation of well-defined annual rings.

“…Second, Bayesian probability, which allows prior knowledge to be included in the assessment of radiocarbon chronologies (Buck et al, 1991), is becoming increasingly used in the evaluation of radiocarbon dating series (e.g. Zeidler et al, 1998, Bayliss et al, 1999Buck et al, 2003). Indeed, a Bayesian probability routine that is suitable for evaluating sequenced data, is incorporated into the OXCAL 14 C calibration program (Bronk Ramsey, 1999, 2001.…”

2004. Bayesian analysis of radiocarbon chronologies: examples from the European Late-glacial.ABSTRACT: Although there are many Late-glacial (ca. 15 000-11 000 cal. yr BP) proxy climate records from northwest Europe, some analysed at a very high temporal resolution (decadal to century scale), attempts to establish time-stratigraphical correlations between sequences are constrained by problems of radiocarbon dating. In an attempt to overcome some of these difficulties, we have used a Bayesian approach to the analysis of radiocarbon chronologies for two Late-glacial sites in the British Isles and one in the Adriatic Sea. The palaeoclimatic records from the three sites were then compared with that from the GRIP Greenland ice-core. Although there are some apparent differences in the timing of climatic events during the early part of the Late-glacial (pre-14 000 cal. yr BP), the results suggest that regional climatic changes appear to have been broadly comparable between Greenland, the British Isles and the Adriatic during the major part of the Late-glacial (i.e. between 14 000 and 11 000 cal. yr BP). The advantage of using the Bayesian approach is that it provides a means of testing the reliability of Late-glacial radiocarbon chronologies that is independent of regional chronostratigraphical (climatostratigraphical) frameworks. It also uses the full radiocarbon inventory available for each sequence and makes explicit any data selection applied. Potentially, therefore, it offers a more 'objective' basis for comparing regional radiocarbon chronologies than the conventional approaches that have been used hitherto.
