Implication

Calibration study reveals an updated 0–50,000-year radiocarbon curve incorporating an interhemispheric offset of 43 ± 23 years, indicating improved Southern Hemisphere chronological accuracy.

Key Points

To update the Southern Hemisphere radiocarbon calibration curve (SHCal13) spanning 0 to 50,000 cal BP using expanded empirical datasets and improved offset modeling.
Incorporated new Southern Hemisphere radiocarbon datasets extending direct measurement coverage to 2145 cal BP, including the ANSTO Younger Dryas Huon pine series.
Modeled periods lacking direct Southern Hemisphere data using Northern Hemisphere IntCal13 records adjusted by an autoregressive process to capture interhemispheric offset variations.
Constructed the comprehensive SHCal13 calibration curve extending back to 50,000 cal BP.
Identified an average interhemispheric radiocarbon offset of 43 ± 23 years relative to the Northern Hemisphere IntCal13 dataset.
