Remote geophysical data acquisition tools, such as gravity and magnetic surveys, have proved very successful in mapping the underlying geology of the Australian continent. Similarly, these geophysical methods can also be applied in Australia’s offshore areas for mapping the continental margin using marine vessels (surface and submarine) and aircraft. The use of airborne magnetic surveys in these environments provides a cost-effective means of mapping large areas of offshore geology. These datasets greatly contribute to the assessment of the petroleum potential of offshore basins through providing an understanding of regional geology, basin architecture, and crustal discontinuities, as well as showing the distribution of igneous rocks.
