SHCAL20 Southern Hemisphere calibration, 0-55,000 years cal BP
Early researchers of radiocarbon levels in South Hemisphere tree rings identified a variable North-South hemispheric offset, necessitating construction of a separate radiocarbon calibration curve for the Southern Hemisphere. We present here SHCal20, a revised calibration curve from 0-55,000 cal BP,...
