A total of 4,612.3 line km of transient EM and magnetic data were acquired. The projected grid coordinates have been supplied in GD2020 / MGA Zone 55. The aim of the survey is to provide geophysical information to support investigations of the regional groundwater system and to better understand the architecture of the aquifers within the upper few hundred metres of the GAB intake beds. It will provide data to allow for the study of the following at a reconnaissance scale: a) trends in regolith thickness and variability b) variations in bedrock conductivity c) conductivity of key bedrock (lithology related) conductive units under cover d) the groundwater resource potential of the region Geoscience Australia (GA) flew the survey as part of the Great Artesian Basin (GAB) Project. The Australian Government, through the National Water Infrastructure Fund – Expansion, commissioned GA to undertake the GAB project. The project is led by GA, in collaboration with the Department of Agriculture, Water and the Environment; Department of Infrastructure, Transport, Regional Development and Communications; the Bureau of Meteorology; and state and territory government water agencies across Queensland, South Australia, New South Wales and the Northern Territory. {"type": "Polygon", "coordinates": [[[145.7609, -28.5354], [152.7068, -28.5354], [152.7068, -20.9138], [145.7609, -20.9138], [145.7609, -28.5354]]]} 145.7609 152.7068 -28.5354 -20.9138 EARTH SCIENCES Electrical and Electromagnetic Methods in Geophysics GEOPHYSICS Published_External Summary document (pdf) [600 KB] documentDigital Summary document (pdf) [600 KB] PDF Processing report [12.6 MB] documentDigital Processing report [12.6 MB] ZIP Processed electromagnetic data [261 MB] documentDigital Processed electromagnetic data [261 MB] ZIP Elevation data and associated images [10 MB] documentDigital Elevation data and associated images [10 MB] ZIP Inverted electromagnetic data [984 MB] documentDigital Inverted electromagnetic data [984 MB] ZIP Flight path information and associated images [7.7 MB] documentDigital Flight path information and associated images [7.7 MB] ZIP Magnetic data and associated images [12.6 MB] documentDigital Magnetic data and associated images [12.6 MB] ZIP
