Brief description

This is a trace ion chemical record from Mill Island (65o33'10"S, 100o47'06"E) 120m ice core. The ice core was drilled in January 2010 using the intermediate-depth ice core drill (ECLIPSE ice coring drill, Icefield Instruments, Inc.). The ice core was then processed in a clean freezer laboratory to retrieve samples for trace ion chemistry measurements. Trace ion chemical measurements were carried out using a suppressed ion chromatograph (IC). Samples were analysed using a Dionex (TM) AS18 ICS- 55 3000 (2 mm) microbore ion chromatograph. The major ion species measured in this data were methanesulfonic acid (CH3SO-3 [MSA]), chloride (Cl-), nitrate (NO-3 ), sulphate (SO2-4 ), sodium (Na+), magnesium (Mg2+), and calcium (Ca2+).
