ABSTRACT Radiocarbon (14C) 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 14C 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 system improves. In this volume the… 
Updated Cariaco Basin 14C Calibration Dataset from 0–60 cal kyr BP
ABSTRACT We present new updates to the calendar and radiocarbon (14C) chronologies for the Cariaco Basin, Venezuela. Calendar ages were generated by tuning abrupt climate shifts in Cariaco Basin
Composition and consequences of the IntCal20 radiocarbon calibration curve
Abstract Radiocarbon calibration is necessary to correct for variations in atmospheric radiocarbon over time. The IntCal working group has developed an updated and extended radiocarbon calibration
Marine20—The Marine Radiocarbon Age Calibration Curve (0–55,000 cal BP)
ABSTRACT The concentration of radiocarbon (14C) differs between ocean and atmosphere. Radiocarbon determinations from samples which obtained their 14C in the marine environment therefore need a
Radiocarbon offsets and old world chronology as relevant to Mesopotamia, Egypt, Anatolia and Thera (Santorini)
Three radiocarbon time-series of archaeological and historical importance from the Mediterranean-Anatolian region are investigated, which indicate offsets from IntCal20 (~0–22 14C years), which are critical for the precise understanding of historical and environmental events across the Mediterranean Basin and Near East.
SHCal20 Southern Hemisphere Calibration, 0–55,000 Years cal BP
ABSTRACT Early researchers of radiocarbon levels in Southern Hemisphere tree rings identified a variable North-South hemispheric offset, necessitating construction of a separate radiocarbon
Recent Developments in Calibration for Archaeological and Environmental Samples
ABSTRACT The curves recommended for calibrating radiocarbon (14C) dates into absolute dates have been updated. For calibrating atmospheric samples from the Northern Hemisphere, the new curve is
Plateaus and jumps in the atmospheric radiocarbon record – potential origin and value as global age markers for glacial-to-deglacial paleoceanography, a synthesis
Abstract. Changes in the geometry of ocean meridional overturning circulation (MOC) are crucial in controlling past changes of climate and the carbon inventory of the atmosphere. However, the
Glacial-to-deglacial reservoir and ventilation ages on the southwest Iberian continental margin
Abstract Detailed assessments of past changes in surface and deep ocean reservoir ages are required to obtain robust 14C-based chronologies of planktic foraminifera and provide insights into ocean
Testing and Improving the IntCal20 Calibration Curve with Independent Records
ABSTRACT Connecting calendar ages to radiocarbon (14C) ages, i.e. constructing a calibration curve, requires 14C samples that represent, or are closely connected to, atmospheric 14C values and that
Plateaus and jumps in the atmospheric radiocarbon record – Potential origin and value as global age markers for glacial-to-deglacial paleoceanography, a synthesis
Abstract. Changes in the geometry of ocean Meridional Overturning Circulation (MOC) are crucial in controlling changes of climate and the carbon inventory of the atmosphere. However, the precise


Radiocarbon calibration uncertainties during the last deglaciation: Insights from new floating tree-ring chronologies
Abstract Radiocarbon dating is the most commonly used chronological tool in archaeological and environmental sciences dealing with the past 50,000 years, making the radiocarbon calibration curve one
Intcal04 Terrestrial Radiocarbon Age Calibration, 0–26 Cal Kyr BP
A new calibration curve for the conversion of radiocarbon ages to calibrated (cal) ages has been constructed and internationally ratified to replace IntCal98, which extended from 0–24 cal kyr BP
INTCAL98 radiocarbon age calibration, 24,000-0 cal BP.
The focus of this paper is the conversion of radiocarbon ages to calibrated (cal) ages for the interval 24,000-0 cal BP (Before Present, 0 cal BP = AD 1950), based upon a sample set of
IntCal09 and Marine09 Radiocarbon Age Calibration Curves, 0–50,000 Years cal BP
The IntCal04 and Marine04 radiocarbon calibration curves have been updated from 12 cal kBP (cal kBP is here defined as thousands of calibrated years before AD 1950), and extended to 50 cal kBP,
High-Precision Radiocarbon Age Calibration for Terrestrial and Marine Samples
Single-year and decadal radiocarbon tree-ring ages are tabulated and discussed in terms of 14 C age calibration. The single-year data form the basis of a detailed 14 C age calibration curve for the
Illuminating Intcal During the Younger Dryas
ABSTRACT As the worldwide standard for radiocarbon (14C) dating over the past ca. 50,000 years, the International Calibration Curve (IntCal) is continuously improving towards higher resolution and
