AUSGeoid98 v.1.0 data files:  (sj52-02)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

SW Canning Basin (La Grange, Munro, Mandora), WA, 1989 (P550), radiometric line data, AWAGS levelled

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected 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.
 This SW Canning Basin (La Grange, Munro, Mandora), WA, 1989 (P550), radiometric line data, AWAGS levelled were acquired in 1989 by the WA Government, and consisted of 37055 line-kilometres of data at 1500m line spacing and 150m 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.

Earthquake Risk in Australia

Earthquake risk maps of Australia were prepared using a computer program which selected events from a regional earthquake file and calculated maximum values of acceleration, velocity and intensity at the nodes of a half degree grid, using a scaling rule of the Kanai form Y = aebmR-c. The parameters a, b and c determined by Esteva and Rosenblueth for the Western United States of America were used. For each node on the grid the Y values were plotted against the return period (years) on logarithmic scales. The results, which were compiled from the period 1960-1972, were extrapolated to give expected values of ground acceleration, ground velocity and intensity for a fifty-year return period. These values were plotted and contoured at the following zone boundaries: [see pdf for details]. The following nine Zone-2 areas together with the maximum expected ground accelerations for a fifty-year return period were delineated: Meckering (12m/s2); Gippsland (5m/s2); Picton (4.9m/s2); Cape Otway (4.5m/s 2); Broome (4.2m/s 2); Lower Eyre Peninsula (3.8m/s2, excludes Port Lincoln); east of Carnarvon (3.2m/s2), and the Simpson Desert (4.0m/s2).

Hay NSW Hydrogeological map of the Murray Basin series 1:250 000

The objectives of hydrogeologically mapping the Murray basin were to generate a set of maps at 1:250 000 scale to: 

show the influence of groundwater on land salinisation and surface water salinity 
delineate useable groundwater resources 
highlight present and potential salinity hazard and 
enhance community awareness and understanding of groundwater systems and processes 

and provide a groundwater data-base for the Murray Basin to facilitate land and water resource management decisions. 
The production of the Murray Basin Hydrogeological Map Series was a major coordinated Government action in the management of groundwater to combat degradation through salinisation and enable sustainable land and water use in the Murray Basin.  The Hydrogeological Map Series was a collaborative effort between the various water authorities of South Australia, Victoria and New South Wales. 
Explaining this product in detail is an article by Evans, W.R. 1992, "The Murray Basin Hydrogeological Map Series", Water pp. 20-23.

Mapping the strontium isotope distribution in northern Australia

Strontium isotopes (87Sr/86Sr) are useful in the earth sciences (e.g., recognising geological provinces, studying geological processes) as well in archaeological (e.g., informing on past human migrations), palaeontological/ecological (e.g., investigating extinct and extant taxa’s dietary range and migrations) and forensic (e.g., validating the origin of drinks and foodstuffs) sciences. Recently, Geoscience Australia and the University of Wollongong have teamed up to determine 87Sr/86Sr ratios in fluvial sediments selected from the low-density National Geochemical Survey of Australia (www.ga.gov.au/ngsa). The initial study targeted the northern parts of the Northern Territory and Queensland in Australia. The samples were taken from a depth of ~60-80 cm depth in floodplain deposits at or near the outlet of large catchments (drainage basins). A coarse grain-size fraction (&lt;2 mm) was air-dried, sieved, milled then digested (hydrofluoric acid + nitric acid followed by aqua regia) to release total strontium. Preliminary results demonstrate a wide range of strontium isotopic values (0.7048 &lt; 87Sr/86Sr &lt; 1.0330) over the survey area, reflecting a large diversity of source rock lithologies, geological processes and bedrock ages. Spatial distribution of 87Sr/86Sr shows coherent (multi-point anomalies and gradients), large-scale (&gt;100 km) patterns that appears to be consistent, in many places, with surface geology, regolith/soil type and/or nearby outcropping bedrock. For instance, the extensive black clay soils of the Barkly Tableland define a &gt;500 km-long northwest-southeast trending low anomaly (87Sr/86Sr &lt; 0.7182). Where carbonate or mafic igneous rocks dominate, a low to moderate strontium isotope signature is observed. In proximity to the outcropping Proterozoic metamorphic provinces of the Tennant, McArthur, Murphy and Mount Isa geological regions, high 87Sr/86Sr values (&gt; 0.7655) are observed. A potential link between mineralisation and elevated 87Sr/86Sr values in these regions needs to be investigated in greater detail. Our results to-date indicate that incorporating soil/regolith strontium isotopes in regional, exploratory geoscience investigations can help identify basement rock types under (shallow) cover, constrain surface processes (e.g., weathering, dispersion), and, potentially, recognise components of mineral systems. Furthermore, the resulting strontium isoscape can also be utilised in archaeological, paleontological and ecological studies that aim to investigate past and modern animal (including humans) dietary habits and migrations.

Darwin Harbour Habitat Mapping Program: Morphology Surfaces

The seafloor morphology mapping approach used to derive this dataset follows Geoscience Australia’s draft National Seafloor GeoMorphology (NSGM) mapping scheme (Nanson and Nichol, 2018). The NSGM scheme is an extension of the Dove et al. (2016) approach, which characterises the seafloor in two sequential parts: Part 1 maps the seafloor Morphology (shape) using bathymetry data, and Part 2 uses additional data to interpret seafloor Geomorphology for those mapped morphological shapes. Part 1 of the NSGM scheme was applied to the project dataset, and consists of three hierarchical levels: Province, Surface and Feature. This dataset contains Surface shapefiles that comprise three categories: Plane (&lt;2 degrees), Slope (2-10 degrees) and Escarpment (&gt;10 degrees).This dataset is published with the permission of the CEO, Geoscience Australia
