The 2017 Fowler Domain and Western Gawler Craton SkyTEM312 AEM Survey was conducted by Geoscience Australia as part of a collaborative project between the Commonwealth of Australia (Geoscience Australia) and its partner the State of South Australia (Department of State Development: Geological Survey of South Australia). Geoscience Australia contracted SkyTEM Australia Pty Ltd to acquire 312M SkyTEM (Interleaved Low Moment and High Moment) AEM data over the Fowler Domain and Western Gawler Craton in South Australia. The raw (binary) data were processed by SkyTEM Aps Denmark, SkyTEM Australia Pty Ltd’s proprietary software.The survey area consists of 4941 line km of time-domain AEM geophysical data acquired in a single survey block located to the east of Ooldea, SA. The traverse lines were flown in a NW - SE orientation with line spacing of 2500 and 5000m. The data have been inverted with the AarhusInv Program using the Aarhus Workbench LCI algorithm. The data release package includes: - Point-located Low Moment & High Moment dB/dt electromagnetic data with associated position, altimeter, orientation, and derived ground elevation data. These data are in ASCII column format with associated ASEG-GDF2 header files. - Point-located conductivity data derived from the inversion of the observed data with the AarhusInv Program using the Aarhus Workbench LCI algorithm. - Gridded data (600m cell size) in ER Mapper® binary raster grid format with associated header files for the conductivity depth slices derived from the Aarhus Workbench LCI data, with and without depth of investigation (DOI) masking. - Gridded magnetics and elevation data in ER Mapper® binary raster grid format with associated header files. - Graphical multiplots, in PNG format, for each flight line showing Aarhus Workbench LCI model sections (with DOI mask line) with profiles of the Low & High moment Z component dB/dt data and the model fit residual. - Contractor supplied Operations Report. - ESRI shapefiles of the flight lines.- Metadata and License files.
