Standardised datasets will help us date climate events and more
Determining numbers like weights, lengths, times and ages relies on a standardised dataset to which to compare, a practice that exists from ancient times. The Egyptian cubit in the 3rd millennium BC was the length from the elbow to the tip of the middle finger. When it comes to pinning down specific events in our Earth's past, luminescence dating is a group of methods commonly employed. It quantifies the last exposure to sunlight of sediments and is widely used to investigate climate events over the most recent 2.6 billion years of our planet. The EU-funded CREDit project will significantly enhance the accuracy of these methods by developing chronological reference datasets for luminescence dating.
