Learn about groundbreaking radioisotope dating techniques in this scientific colloquium presented at the Centre for Quantum Technologies. Explore how the Atom Trap Trace Analysis (ATTA) method enables precise dating of water and ice samples between 100,000 and 1 million years old - beyond the capabilities of traditional carbon dating. Discover how this innovative technique captures and detects individual atoms of noble-gas isotopes like 81Kr, 85Kr, 39Ar, and 41Ca at extremely low abundances of 10-17 to 10-11. Follow the worldwide scientific collaboration using ATTA to map groundwater flow in major aquifers and date ancient ice cores from Antarctica, Greenland, and the Tibetan Plateau. Gain insights into how this technology, developed over six decades, is now accessible to the broader earth science community for advanced geological research and understanding Earth's history.
