Datasets

The mesac Open Data Portal datasets contain detailed records of seismic surveys and geochemical data, and they are made available here to industry, researchers and the public.

  • Quaternary dune ranges

    An interpretation of Quaternary dune ranges for South Australian palaeodrainage systems, which are marked by sand ridges and reworked sand on topographic highs during the Quaternary. Those dune systems were interpreted from outcrops, Landsat data,...
