Description

Soil samples were collected and analysed from five locations within the East Trinity wetland to examine the temporal changes in the soil chemistry that had occurred since the inundation of this wetland.

Data Collection Start Date

9-2013

Data Collection End Date

9-2013

Methodology

Soil profiles had previously been collected and analysed at or close to these sites (i.e. within 10 m).

Triplicate intact soil profiles were collected from each site to a depth of 1.2 m. Soil samples were collected from a total of 14 sampling depths (i.e. 0-5 cm, 5-10 cm, 10-15 cm, 15-20 cm, then every 10 cm to 1.2 m) using a range of implements (i.e. spades, and augers). At each location soil pits were dug using a spade to approximately 0.2 m, and then a gouge auger or Russian D-section auger was used to obtain soil samples below the base of the pit down to 1.2 m.

The soil field pH and redox potential (Eh) were determined on the triplicate samples using calibrated electrodes linked to a TPS WP-80 meter; Eh measurements are presented versus the standard hydrogen electrode.

Soil samples were stored in sealed 50 mL centrifuge tubes. Each centrifuge tube was filled to the top, capped and each cap was wrapped in Parafilm to minimise the potential for sulfide oxidation. The soil samples were transported in cold iceboxes and were stored refrigerated on return to the Southern Cross GeoScience laboratory.
