Analysis of an Antarctic ice core by ion chromatography (Mg2+, Na+, Cl−, and SO42− content)
This study presents the ion chromatography analysis of an Antarctic ice core (IC-3; 85°59’S, 81°35’W) and discusses Mg2+, Na+, Cl-, and SO42− concentration data. The Mg2+, Na+ and Cl- concentration peaks, are environmentally interpreted as winter layers and lower concentrations are considered as sum...
