Multi-Proxy Tree-Ring Dating during the Younger Dryas
The world's longest tree-ring chronology comprises thousands of oak and pine series from Germany and continuously covers the Holocene back to 12,325 cal BP. A lack of relict wood from the Younger Dryas cold reversal ca. 12,900–11,700 cal BP, however, challenges the extension of this absolutely dated ring width record further back in time. Here, we combine 646 high-resolution stable oxygen isotope and 795 radiocarbon measurements from subfossil pi…
Radiocarbon Protocols and First Intercomparison Results From the Chronos 14 Carbon-Cycle Facility, University of New South Wales, Sydney, Australia
The Chronos 14 Carbon-Cycle Facility is a new radiocarbon laboratory at the University of New South Wales, Australia. Built around an Ionplus 200 kV MIni-CArbon DAting System (MICADAS) Accelerator Mass Spectrometer (AMS) installed in October 2019, the facility was established to address major challenges in the Earth, Environmental and Archaeological sciences. Here we report an overview of the Chronos facility, the pretreatment methods currently e…
Quality Dating: A Well-Defined Protocol Implemented at ETH for High-Precision 14C-Dates Tested on Late Glacial Wood
Advances in accelerator mass spectrometry have resulted in an unprecedented amount of new high-precision radiocarbon ( 14 C) -dates, some of which will redefine the international 14 C calibration curves (IntCal and SHCal). Often these datasets are unaccompanied by detailed quality insurances in place at the laboratory, questioning whether the 14 C structure is real, a result of a laboratory variation or measurement-scatter. A handful of intercomp…
Illuminating Intcal During the Younger Dryas
As the worldwide standard for radiocarbon ( 14 C) dating over the past ca. 50,000 years, the International Calibration Curve (IntCal) is continuously improving towards higher resolution and replication. Tree-ring-based 14 C measurements provide absolute dating throughout most of the Holocene, although high-precision data are limited for the Younger Dryas interval and farther back in time. Here, we describe the dendrochronological characteristics …
The IntCal20 Northern Hemisphere Radiocarbon Age Calibration Curve (0–55 cal kBP)
Radiocarbon ( 14 C) ages cannot provide absolutely dated chronologies for archaeological or paleoenvironmental studies directly but must be converted to calendar age equivalents using a calibration curve compensating for fluctuations in atmospheric 14 C concentration. Although calibration curves are constructed from independently dated archives, they invariably require revision as new data become available and our understanding of the Earth syste…
Speed Dating: A Rapid Way to Determine the Radiocarbon Age of Wood by EA-AMS
Radiocarbon measurements in tree rings can be used to estimate atmospheric 14 C concentration and thereby used to create a 14 C calibration curve. When wood is discovered in construction sites, rivers, buildings, and lake sediments, it is unclear if the wood could fill gaps in the 14 C calibration curve or if the wood is of historical interest until the age is determined by dendrochronology or 14 C dating. However, dendrochronological dating is s…
