Short summary
We analyse 8 samples from the East Greenland Ice-core Project (EGRIP) ice core, Greenland, using an underexplored method: single particle time of flight analysis. For the first time, we investigated thousands of particles from different climatic stages while applying a new approach to estimate particle sizes based on prior data. We characterise particles and clusters providing new insights on trace elements in ice sheets. This approach has enormous potential for analysing million-year-old ice.
