The IntCal20 Northern Hemisphere Radiocarbon Age Calibration Curve (0–55 cal kBP)

ABSTRACT Radiocarbon ( 14 C) ages cannot provide absolutely dated chronologies for archaeological or paleoenvironmental studies directly but must be converted to calendar age eq...

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 extende...

The North Atlantic atmosphere-sea surface 14C gradient during the Younger Dryas climatic event

Radiocarbon calibration beyond 20,000 ¹⁴C yr B.P. by means of planktonic foraminifera of the Iberian Margin

We present a new set of 14 C ages obtained by accelerator mass spectrometry (AMS) on planktonic foraminifera from a deep-sea core collected off the Iberian Margin (MD952042). Th...

Elastic Tie-Pointing—Transferring Chronologies between Records via a Gaussian Process

We consider a general methodology for the transferral of chronologies from a master reference record containing direct dating information to an undated record of interest that d...

Comparison of ¹⁴C and U-Th Ages in Corals from IODP #310 Cores Offshore Tahiti

Shallow-water tropical corals can be used to calibrate the radiocarbon timescale. In this paper, we present a new data set based on the comparison between 14 C ages and U-Th age...

²³⁰Th-²³⁴U and ¹⁴C Ages Obtained by Mass Spectrometry on Corals

In 1988, Fairbanks conducted a drilling expedition off the south coast of Barbados to recover submerged corals contemporaneous with the last deglaciation. Core recovery was exce...
