Macquarie Island soil property data - January to March, 2013

Replicate samples were collected from each location and a single sample was collected from 50cm depth below the surface. Soil samples were collected in plastic sample jars.

Column labels Sample - Unique numerical sample identifier Location - Location identifier code Easting - easting (m) Northing - northing (m) Depth - Depth of collection (cm) below surface % Organic - Organic matter determined by loss on ignition at 550 degrees centigrade % 2mm - Proportion of sample by mass with particle size greater than 2mm determined by dry sieving % 63 um - Proportion of sample by mass with particle size greater than 63 micron, less than 2mm determined by dry sieving % less than 63 um - Proportion of sample by mass with particle size less than 63 micron determined by dry sieving % Water - Proportion of water in field collected sample, determined by loss of mass after drying at 80deg C until constant weight Cond uS/cm - Electrical conductivity of soil determined using field conductivity probe after addition of milli-Q water and shaking for 2 h pH - pH of soil determined using field pH probe after addition of milli-Q water and shaking for 2 h
