<div>The soil gas database table contains publicly available results from Geoscience Australia's organic geochemistry (ORGCHEM) schema and supporting oracle databases for gas analyses undertaken by Geoscience Australia's laboratory on soil samples taken from shallow (down to 1 m below the surface) percussion holes. Data includes the percussion hole field site location, sample depth, analytical methods and other relevant metadata, as well as the molecular and isotopic compositions of the soil gas with air included in the reported results. Acquisition of the molecular compounds are by gas chromatography (GC) and the isotopic ratios by gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS). The concentrations of argon (Ar), carbon dioxide (CO₂), nitrogen (N₂) and oxygen (O₂) are given in mole percent (mol%). The concentrations of carbon monoxide (CO), helium (He), hydrogen (H₂) and methane (C₁, CH₄) are given in parts per million (ppm). Compound concentrations that are below detection limit (BDL) are reported as the value -99999. The stable carbon (¹³C/¹²C) and nitrogen (¹⁵N/¹⁴N) isotopic ratios are presented in parts per mil (‰) and in delta notation as δ¹³C and δ¹⁵N, respectively.</div><div><br></div><div>Determining the individual sources and migration pathways of the components of natural gases found in the near surface are useful in basin analysis with derived information being used to support exploration for energy resources (petroleum and hydrogen) and helium in Australian provinces. These data are collated from Geoscience Australia records with the results being delivered in the Soil Gas web services on the Geoscience Australia Data Discovery portal at https://portal.ga.gov.au which will be periodically updated.</div>

<div>Join the team behind the Digital Atlas of Australia to explore how they are collaborating with government partners to transform how we access and use location data. </div><div>&nbsp;</div><div>In this webinar, key partner agencies - earlier adopters of the Australian Government’s new geospatial platform - will share valuable insights on how they are using the Digital Atlas. You will learn how the Australian Bureau of Statistics, the Department of Social Services, and the Department of Industry, Science and Resources, are making their data easier to access and use and the innovative, interactive maps and tools they’re creating collaboratively to unlock place-based insights to inform their policy, program and service delivery.&nbsp;&nbsp;</div><div>&nbsp;</div><div>Whether you're a seasoned professional or new to geospatial data, this webinar will showcase how the Digital Atlas is transforming decision-making and driving cross-sector innovation. &nbsp;</div><div>&nbsp;</div><div><strong>About the Digital Atlas of Australia</strong></div><div>Developed and delivered by Geoscience Australia, the Digital Atlas provides access to hundreds of curated trusted national datasets in one location. It uses location as the connecting thread to bring together data on Australia’s geography, people, economy and the environment to support informed place-based decisions across various sectors.</div><div><strong>&nbsp;</strong></div><div>Learn more about the Digital Atlas: https://digital.atlas.gov.au/pages/about</div>
