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. Column labels Sample - Unique numerical sample identifier Depth - Depth of collection: surface = 0 cm, depth = 50 cm below surface Location - Location identifier code Easting - easting (m) Northing - northing (m) Elevation (m) - Height above sea level (m) Parisotoma insularis - Abundance of Parisotoma insularis in core sample Folsotoma punctata - Abundance of Folsotoma punctata in core sample Tullbergia bisetosa - Abundance of Tullbergia bisetosa in core sample Ceratophysella denticulata - Abundance of Ceratophysella denticulata in core sample Hypogastrura viatica - Abundance of Hypogastrura viatica in core sample Hypogastrura purpurescens - Abundance of Hypogastrura purpurescens in core sample Cryptopygus antarcticus - Abundance of Cryptopygus antarcticus in core sample Cryptopygus caecus - Abundance of Cryptopygus caecus in core sample Cryptopygus lawrencii - Abundance of Cryptopygus lawrencii in core sample Cryptopygus tricuspus - Abundance of Cryptopygus tricuspus in core sample Polykatianna davidii - Abundance of Polykatianna davidii in core sample Lepidocyrtus sp. - Abundance of Lepidocyrtus sp. in core sample Megalothorax sp. - Abundance of Megalothorax sp. in core sample Acarina 1 - Abundance of Acarina 1 in core sample Acarina 2 - Abundance of Acarina 2 in core sample Acarina 3 - Abundance of Acarina 3 in core sample Acarina 4 - Abundance of Acarina 4 in core sample Acarina 5 - Abundance of Acarina 5 in core sample Acarina 6 - Abundance of Acarina 6 in core sample Acarina 7 - Abundance of Acarina 7 in core sample Acarina 8 - Abundance of Acarina 8 in core sample Big dark tick - Abundance of Big dark tick in core sample Spider - Abundance of Spider in core sample Microscolex macquariensis - Abundance of Microscolex macquariensis in core sample Enchytraeus albidus - Abundance of Enchytraeus albidus in core sample Nematode species - Abundance of Nematode species in core sample Styloniscus otakensis - Abundance of Styloniscus otakensis in core sample Harpacticoid - Abundance of Harpacticoid in core sample Puhuruhuru patersoni - Abundance of Puhuruhuru patersoni in core sample Stenomalium sp. - Abundance of Stenomalium sp. in core sample Thinophilus (fly) - Abundance of Thinophilus (fly) in core sample Australimyza - Abundance of Australimyza in core sample Grasshopper? - Abundance of Grasshopper? in core sample Slug sp. - Abundance of Slug sp. in core sample 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.
