Hence, we would like to be able to use C wiggle-matching to provide a comparable level of precision and reliability, particularly on shorter tree-ring sequences (~30 annual growth rings) that up until now would not routinely be sampled.We present the results of AMS wiggle-matching five oak tree-ring sequences, spanning the period covered by the vast majority of surviving Medieval buildings in England (about AD 1180–1540) when currently we have only decadal and bidecadal calibration data.This book takes the pulse of how archaeology, science-based research methods and the Bible interface at the beginning of the 21st century.The book brings together leading archaeologists, Egyptologists, Biblical scholars, radiocarbon dating specialists and other researchers who have embraced radiocarbon dating as a significant tool to test hypotheses concerning the historicity of aspects of the Old Testament or Hebrew Bible (hereafter, simply the Bible).Facilitated by a floating varve chronology and relatively stable 14C reservoir ages, the results show the possibility to assess the contribution of old carbon solely based on the 14C wiggle-matching of bulk sediments.

Methods: High precision conventional dating, AMS, interpretation in terms of climate change.

Here we report a new high-precision 14C wiggle-match age of A. 946 ± 3 obtained from a 264 year old tree trunk (with bark) killed during the eruption, using the Ox Cal's Bayesian modeling approach with 27 sequentially sampled annual rings of decadal intervals.

The new chronology conforms well to the calendar date of A. 946 for the eruption inferred from historical documentary evidence. Since the stratospheric volcanic sulfates are the main cause of large-scale climate perturbations, this finding indicates that the Millennium eruption of Changbaishan volcano might have limited regional climatic effects, rather than global or hemispheric impact as implied by its magnitude.

Present topics: Periods with increasing atmospheric 14C concentrations (Hallstatt plateau, younger Dryas, Maunder minimum).
