Abstract

Radiocarbon is a useful means for obtaining the age of death of a carbon-bearing organism. With the help of international scientists, a robust calibration has been developed back to 50,000 years ago. Annual tree rings provide the calibration back to ~12,594 year BP and corals and forams helped refine this calibration back to 50,000 years ago using uranium-series dating in conjunction with radiocarbon dating. Corals have also played a role in trying to understand the oceanic uptake of CO2 and for tracking ocean currents and circulation.
