IntCal13 and Marine13 Radiocarbon Age Calibration Curves 0–50,000 Years cal BP
The IntCal09 and Marine09 radiocarbon calibration curves have been revised utilizing newly available and updated data sets from 14C measurements on tree rings, plant macrofossils, speleothems,…
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…
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,…
The Holocene Asian Monsoon: Links to Solar Changes and North Atlantic Climate
A 5-year-resolution absolute-dated oxygen isotope record from Dongge Cave, southern China, provides a continuous history of the Asian monsoon over the past 9000 years, and shows that some, but not all, of the monsoon variability at these frequencies results from changes in solar output.
A High-Resolution Absolute-Dated Late Pleistocene Monsoon Record from Hulu Cave, China
The record links North Atlantic climate with the meridional transport of heat and moisture from the warmest part of the ocean where the summer East Asian Monsoon originates and generally agrees with the timing of temperature changes from the Greenland Ice Sheet Project Two (GISP2).

Marine04 Marine Radiocarbon Age Calibration, 0–26 Cal Kyr Bp
New radiocarbon calibration curves, IntCal04 and Marine04, have been constructed and internationally ratified to replace the terrestrial and marine components of IntCal98. The new calibration data…
Millennial- and orbital-scale changes in the East Asian monsoon over the past 224,000 years
An absolute-dated oxygen isotope record from Sanbao cave, central China, is presented that completes a Chinese-cave-based record of the strength of the East Asian monsoon that covers the past 224,000 years, supporting the idea that tropical/subtropical monsoons respond dominantly and directly to changes in Northern Hemisphere summer insolation on orbital timescales.
The IntCal20 Northern Hemisphere Radiocarbon Age Calibration Curve (0–55 cal kBP)
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…
Timing, Duration, and Transitions of the Last Interglacial Asian Monsoon
Thorium-230 ages and oxygen isotope ratios of stalagmites from Dongge Cave, China, characterize the Asian Monsoon and low-latitude precipitation over the past 160,000 years, indicating that insolation triggered the final rise to full interglacial conditions.
