RECENT DEVELOPMENTS IN CALIBRATION FOR ARCHAEOLOGICAL AND ENVIRONMENTAL SAMPLES

Abstract:
<jats:title>ABSTRACT</jats:title> <jats:p>The curves recommended for calibrating radiocarbon (<jats:sup>14</jats:sup>C) dates into absolute dates have been updated. For calibrating atmospheric samples from the Northern Hemisphere, the new curve is called IntCal20. This is accompanied by associated curves SHCal20 for the Southern Hemisphere, and Marine20 for marine samples. In this “companion article” we discuss advances and developments that have led to improvements in the updated curves and highlight some issues of relevance for the general readership. In particular the dendrochronological based part of the curve has seen a significant increase in data, with single-year resolution for certain time ranges, extending back to 13,910 calBP. Beyond the tree rings, the new curve is based upon an updated combination of marine corals, speleothems, macrofossils, and varved sediments and now reaches back to 55,000 calBP. Alongside these data advances, we have developed a new, bespoke statistical curve construction methodology to allow better incorporation of the diverse constituent records and produce a more robust curve with uncertainties. Combined, these data and methodological advances offer the potential for significant new insight into our past. We discuss some implications for the user, such as the dating of the Santorini eruption and also some consequences of the new curve for Paleolithic archaeology.</jats:p>Oxygen isotope dating of oak and elm timbers from the portcullis windlass, Byward Tower, Tower of London
