Chemical concentrations of trace ions at the Mill Island ice core site
Listed in NASA Earthdata CMR
This is a trace ion chemical record from Mill Island (65o33'10"S, 100o47'06"E) 120m ice core.
Description
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+).

Anions (i.e. MSA, Cl-, SO2-4 , and NO-3 ) were analysed using an IonPac (R) AS18 separation column and AG18 guard column. Cation (i.e. Na+, Mg2+, and Ca2+) analysis was performed using CS12A separation columns. The system performed anion and cation analysis simultaneously using dual isocratic pumps.
