Analysis of an Antarctic ice core by ion chromatography (Mg 2+ , Na + , Cl - , and SO 4 2- content)

Abstract

This study presents the ion chromatography analysis of an Antarctic ice core (IC - 3 ; 85°59 ' S , 81°35 ' W) and discusses Mg 2+ , Na + , Cl - , and SO 4 2− concentration data . The Mg 2+ , Na + and Cl - concentration peaks , are environmentally interpre - ted as winter layers and lower concentrations are considered as summer ones and can be directly associated to sea spray . The higher concentrations in winter are probably caused by transport of marine air masses over the Antarctic ice sheet , which are stronger in this season . There are probably additional sources for Cl −
