This package contains Airborne Electromagnetic (AEM) data from the “SkyTEM helicopter EM Ord-Keep rivers region” survey which was flown over the Ord-Keep Rivers Region, Western Australia/Northern Territory, Australia during May - June 2017. High resolution magnetics were also acquired during the flights. As shown in Figure 1, the area is located in the 1:250000 map sheets of SD52-14 (Cambridge Gulf), SD52-11 (Port Keats) and SD 52-15 (Auvergne) near the town of Kununurra. 8100 line km of TEM and magnetic data were acquired. The projected grid coordinates have been supplied in GDA94 MGA Zone 52. The aim of the survey is to provide geophysical information to support investigations of the regional groundwater system and identify regional groundwater sources. It will provide data to allow for the modelling 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 e) palaeovalley systems known to exist in the region. This report lists the SkyTEM system information and specifications relevant for this survey, and describes the processing carried out on the data. Geoscience Australia commissioned the survey as part of the Exploring for the Future (EFTF) program. The EFTF program is led by Geoscience Australia (GA), in collaboration with the Geological Surveys of the Northern Territory, Queensland, South Australia and Western Australia, and is investigating the potential mineral, energy and groundwater resources in northern Australia and South Australia. The EFTF is a four-year $100.5 million investment by the Australian Government in driving the next generation of resource discoveries in northern Australia, boosting economic development across this region (https://www.ga.gov.au/eftf).
