All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).
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+). 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.
