<p>This dataset comprises a comprehensive archive of soil subsite samples collected from TERN Ecosystem Surveillance monitoring plots across Australia. In addition to the 1-meter soil pit, soil subsite samples are taken from nine locations across the 1-hectare monitoring plot from three depths (0-10cm, 10-20cm and 20-30cm). Each of the nine subsites are selected to represent the variation in micro habitats across the monitoring plot. Collected following the standardised Ecosystem Surveillance methodology, the dataset includes over 33,600 soil subsite samples archived in the TERN Australia Soil and Herbarium Collection, located at the University of Adelaide's Waite Campus.</p> <p>Each record includes detailed metadata such as voucher barcode for soil collected from the three depths at each of the nine subsites, site and visit information and sampling details. Soil subsite samples are accessible and available for loan upon request through the EcoPlots Samples portal via an Expression of Interest.</p>

<p>This dataset comprises a comprehensive archive of soil metagenomic samples collected from TERN Ecosystem Surveillance monitoring plots across Australia. In addition to the nine subsite locations across the 1-hectare monitoring plot, soil metagenomic samples are collected from the top layer of soil. These samples can support microbial DNA analysis, including assessments of soil biodiversity, microbial function and ecological responses to environmental change. Each of the nine subsites are selected to represent the variation in micro habitats across the monitoring plot. Collected following the standardised Ecosystem Surveillance methodology, the dataset includes over 10,400 soil metagenomic samples archived in the TERN Australia Soil and Herbarium Collection, located at the University of Adelaide's Waite Campus. </p> <p>Soil metagenomic samples are preserved under climate-controlled conditions to maintain DNA integrity for future molecular analysis. These samples are openly available to researchers and support a broad range of ecological, agricultural, and microbiological studies. Each record includes detailed metadata such as voucher barcode, site and visit information and sampling details. Soil subsite samples are accessible and available for loan upon request through the EcoPlots Samples portal via an Expression of Interest.</p>
