New airborne geophysical data to aid salinity management
12 September 2007
Airborne geophysical survey data from Billabong Creek in New South Wales and Honeysuckle Creek in Victoria have been incorporated into the National Airborne Geophysical Database.
The data, released on Tuesday 11th September, was gathered through a pilot project designed to test the relevance of airborne geophysical data for mapping the distribution of salt-affected land and sub-surface salt. The aim of the project was to map the sub-surface geology to aid in the mapping of groundwater movement and subsequent salt mobilisation.
The project, funded by the Murray Darling Basin Commission, was developed from the National Geophysics Project originally sponsored under the National Dryland Salinity Program.
Two surveys were conducted to collect airborne electromagnetic data with separate surveys conducted to collect airborne magnetic & radiometric data.
The magnetic and radiometric surveys collected 30,862 and 13,770 line kilometres of data for Billabong Creek and Honeysuckle Creek respectively. The electromagnetic surveys collected 5,522 and 6,082 line kilometres of data for Billabong Creek and Honeysuckle Creek respectively.
The magnetic and radiometric data is available for free download via GADDS.
The AEM data only is available on CD-ROM at a cost of $99.00 per CD. To obtain these products please contact the Geoscience Australia Sales Centre, GPO Box 378, Canberra, ACT, 2601.
