Abstract

A SkyTEM airborne electromagnetic (AEM) survey was flown during the period 09 to 24 August 2017 in the Daly River Region, Northern Territory, Australia. The area is located in the 1:250000 map sheets, SD52-08 (Pine Creek), SD52-12 (Fergusson River), SD52-16 (Delamere), SD53-09 (Katherine) and SD53-13 (Larrimah) south-southeast of the city of Darwin. Approximately 3379 line kilometres 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, identify regional groundwater sources and mitigate risk in irrigation development. 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
