Description

Soil cores were collected from numerous locations across the Macquarie Island Isthmus. Replicate samples were collected from each location and a single sample was collected from 50cm depth below the surface. Soil cores were cylindrical, diameter 70 mm, depth 70 mm and included surface vegetation where present. Invertebrates were extracted from the soil core using a heat gradient process. Specimens were preserved in ethanol following extraction.
Invertebrates were identified under microscope to the lowest practicable level, which was species level for most taxa. Mites (Acarina) were identified to morphotype.

The easting, northing and elevation for each sample site was collected by Lauren Wise of the AAD and Josie van Dorst of the University of NSW using a Trimble differential GPS and the post processing was done by Dan Wilkins of the AAD. The elevations were derived using the global geoid model EGM96.
To convert the eastings and northings of the sample sites to eastings and northings on the WGS84 datum of the Australian Antarctic Data Centre's GIS data representing the Macquarie Island station buildings and structures, add 1.40 metres to the eastings and 0.2 metres to the northings as given on page 3 of the survey report "Macquarie Island OSG Survey Campaign, Voyage 8 Round Trip, March 2002" by John VanderNiet and Nick Bowden of the Office of the Surveyor General, Tasmania.
