From light signals to sediment pathways : developing luminescence as a sediment tracing tool

A novel luminescence-based method reveals sediment pathways and dynamics in the Wadden Sea, a UNESCO World Heritage site vulnerable to climate change. By measuring light exposure history in individual sand grains using optimized imaging techniques (EMCCD camera), researchers can track how added sand mixes with native sediments during coastal nourishment—a critical process for erosion management. Field experiments quantified subaqueous bleaching of luminescence signals, providing insights into complex sediment movement in tidal channels and beaches, such as the Ameland Inlet. This approach offers a precise tool to understand and preserve fragile coastal ecosystems.
