Major elemental concentrations from NGRIP ice core across the interstadial period GI-21.2 D. Della Lunga, W. Müller, S. O. Rasmussen, A. M. Svensson, and P. Vallelonga

Short summary
In our study we combined the wealth of information provided by Greenland ice cores with an ultra-high-resolution technique well known in geoscience (laser ablation). Our set-up was developed and applied to investigate the variability in concentration of ions across a rapid climatic change from the oldest part of the last glaciation, showing that concentrations drop abruptly from cold to warm periods, representing a shift in atmospheric transport that happens even faster than previously thought.
