With this blog we would like to inform you about our ECHOES project. Exact Chronology of Early Societies (ECHOES) is a 5-year project funded by the European Research Council and based at the University of Groningen. Its central aim is to develop a new approach to radiocarbon dating, one that is accurate to the exact calendar year. The technique will be built on the recent discovery of annual rises, or ‘spikes’, in the concentration of radiocarbon in the atmosphere.
