A detailed investigation of major ion concentrations of snow and ice in the summit region of Penny Ice Cap (PIC) was performed to determine the effects of summer melt on the glaciochemical time‐series. While ion migration due to meltwater percolation makes it difficult to confidently count annual layers in the glaciochemical profiles, time‐series of these parameters do show good structure and a strong one year spectral component, suggesting that annual to biannual signals are preserved in PIC glaciochemical records.
