Short summary
Impurities in ice cores can be preferentially located at the boundaries between crystals of ice, impacting the interpretation of high-resolution data collected from ice core samples. Through use of a modelling framework, we demonstrate that one-dimensional signals can be significantly affected by this association, meaning high-resolution measurements must be carefully designed. Accounting for this effect is important for interpreting ice core data, especially for deep ice samples.
