Kakadu Stage II 1, NT, 1983 (P616), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the Kakadu Stage II, NT, 1983 survey were acquired in 1982 by the NT Government, and consisted of 46936 line-kilometres of data at a line spacing between 150m and 150m, and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Lessons from Cyclone Larry in co-ordinated earthquake post-disaster surveys

Natural disasters provide an invaluable opportunity to capture data for improving our
understanding of risk. Observed damage types and their predominance provide useful
insights into the factors contributing to building vulnerability and consequential
community risk. They also facilitate the appraisal of mitigation measures directed at
reducing that risk where it is found to be high. Survey activities that followed the impact
of Tropical Cyclone Larry have highlighted the benefits of a co-ordinated survey response
to natural hazard impacts. The response to this event involved liaison with local
emergency management and the broad participation of recognised wind engineering
experts. Survey techniques were refined to achieve a more efficient and comprehensive
approach that ensured consistency, utility and transferability of the data for all
collaborators. The refined approach proved very successful and may provide a useful
model for similar post-disaster exercises directed at earthquake damage. The sudden
nature by which earthquakes inflict damage without warning points to having
arrangements already established beforehand for the best survey outcomes. Proposals
for advancing such preplanning are presented.

Cooper Basin Source Rock Geochemistry: Regional Hydrocarbon Prospectivity of the Cooper Basin Data Pack 2

The Cooper Basin is a Pennsylvanian to Middle Triassic intracratonic basin in northeastern South Australia and southwestern Queensland (Gravestock et al., 1998; Draper, 2002; Carr et al., 2016). Exploration activity in the region has recently expanded with explorers pursuing a range of newly-identified unconventional hydrocarbon plays (Goldstein et al., 2012; Menpes et al., 2013; Greenstreet, 2015). In support of this ongoing exploration activity in the region, Hall et al. (2016a) reviewed the Cooper Basin source rock geochemistry and maturity based on a compilation of updated and quality controlled publically available total organic carbon (TOC), Rock-Eval pyrolysis and vitrinite reflectance data. This is the first study of its kind to be undertaken for the Cooper Basin as a whole and builds on the previous work of Boreham &amp; Hill (1998) in South Australia. This data pack contains the supplementary material accompanying this report.
The distribution, quantity, quality and thermal maturity of the organic matter were described for all formations within the PennsylvanianÂ¿Permian Gidgealpa Group and collectively for the formations within the Triassic Nappamerri Group (Hall et al., 2015a, 2016a). Where possible, data were also analysed by lithology. The total organic carbon (TOC) and Rock-Eval pyrolysis data were used to investigate source rock quality, maturity and kerogen type. Original Hydrogen Index (HIo) values for each formation and lithology were determined through the analysis of a subset of low maturity samples and through application of a maturity correction based on Cooper Basin-specific kinetics (Deighton et al., 2003; Mahlstedt et al., 2015). Where data density permits, maps of present day TOC content and both present day HI and original HI were created, showing the spatial variation in the amount and quality of the source rock present now and prior to the onset of hydrocarbon generation.
This data pack includes all TOC and Rock Eval data for the Cooper Basin stratigraphic evaluated in Hall et al. (2016a). It also includes the grids of present day TOC for the shale and/or coaly shale intervals, along with the grids of present day and original HI by formation. These datasets quantify the spatial distribution, quantity and quality of the source rocks and provide important insights into the hydrocarbon prospectivity of the Cooper Basin (Hall et al., 2015b; Kuske et al., 2015).
This was the first study to be completed as part of the Australian Petroleum Source Rock Mapping project, a new work program being undertaken at Geoscience Australia to improve our understanding of the petroleum resource potential of Australia's sedimentary basins.
