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 data record describes work conducted by Thomas Mooney on Macquarie Island during the 2008/09 and 2009/10 field seasons.
The experimental design of this work included sampling three sites located in uncontaminated areas, within the vicinity of the Macquarie Island research station. One transect (length: 50 m) was located per site; each transect spanned a soil carbon gradient, from sandy to peaty soil types. Each 50 m transect included 10 plots (plot size 1 m2). Seven pairs of soil cores were collected from each plot. Soil core dimensions were 70 mm diameter x 70 mm deep. Soil core pairs were spiked with Special Antarctic Blend (SAB) diesel; one unspiked control and six spiked concentrations per plot. After spiking, cores were incubated under field-realistic conditions for 15 days. After incubation, one core per pair was used for invertebrate extraction, the other was used for soil physicochemical analysis. Percentage cover of plant species and bare ground were surveyed for each plot.
The data provided with this record include details of soil core fuel spike, springtail species counts, soil physicochemical properties and vegetation cover within plots.
This work formed part of TMs PhD research (Mooney 2013). PhD supervisors were Dr Catherine King (AAD) and Associate Professor Nigel Andrew (UNE). Funding was provided by AAS projects 2933 and 4100 (King) and 4036 (Snape) and an Australian Postgraduate Award to TM (University of New England, Australia).

There were some issues with heterogeneity of the fuel spike into the soil cores that prevented use of Total Petroleum Hydrocarbon (TPH) concentrations, measured via gas chromatography. The soil fuel concentration data provided is therefore calculated, based on volume of fuel added to cores on a soil dry mass basis.
