AUSGeoid98 v.1.0 data files: Lagrange (se51-10)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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.

Tasmanian Gravity Data (P198849), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 Tasmanian Gravity Data (P198849) contains a total of 92 point data values acquired at a spacing between 20 and 100 metres. The data is located in TAS and were acquired in 1988, under project No. 198849 for None.

AusAEM1 Interpretation Data Package

The AusAEM1 airborne electromagnetic survey extends across an area exceeding 1.1 million km2 over Queensland and the Northern Territory. Approximately 60,000 line kilometres of data were acquired at a nominal line spacing of 20 km (Ley-Cooper et al., 2020). To improve targeting and outcomes for mineral, energy and groundwater exploration, we conducted a regional interpretation of this dataset to characterise the subsurface geology of northern Australia. The interpretation includes the depth to chronostratigraphic surfaces, compilation of stratigraphic relationship information, and delineation of structural and electrically conductive features. In addition to help connecting correlative outcropping units separated by up to hundreds of kilometres, the results led to 3D mapping of palaeovalleys and prompted further investigation of electrical conductors and their relationship to structural features and mineralisation. Approximately 200,000 regional depth point measurements, each attributed with detailed geological information, are an important step towards a national geological framework, and offer a regional context for more detailed, smaller-scale AEM surveys. Refer to Wong et al., (2020) for more details on the AusAEM1 interpretation.

Survey of Kalgoorlie Earthquake Damage

Australia has a low seismicity when compared to countries located along tectonic plate boundaries.  Seismic risk, however, is the combination of hazard, community exposure and infrastructure vulnerability.  The legacy of older unreinforced masonry buildings is a particular subset of the built environment that may contribute disproportionately to community risk.  Documented information on the damage to buildings caused by earthquake events is fundamental to understanding this risk.
The Earthquake
Earlier this year on the 20th April a magnitude 5.0 (ML) earthquake shook the Western Australian goldfields town of Kalgoorlie.  The earthquake was shallow (1.7 km) and was located immediately south of the business district of the Kalgoorlie suburb of Boulder (refer Figure 1).  The severity of ground motion was found to vary markedly across the town with the older masonry building stock in Boulder experiencing a greater intensity of shaking than the corresponding building age group in the Kalgoorlie business district 4 km away.  The event has provided the best opportunity to examine the earthquake vulnerability of Australian buildings since the Newcastle Earthquake of the 28th December 1989, over twenty years prior.
The Survey
Following the earthquake Geoscience Australia (GA) arranged a staged collaborative survey that would capture information from which vulnerability knowledge could be derived.

Georgetown ppm thorium grid geodetichg

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 radiometric thorium grid has a cell size of 0.00042 degrees (approximately 45m) and shows thorium element concentration of the Georgetown, Qld, 1998/99 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1998 by the QLD Government, and consisted of 65969 line-kilometres of data at 200m line spacing and 80m terrain clearance.

Hydrology of Lake Amadeus, a groundwater-discharge playa in central Australia

Lake Amadeus, a large playa in central Australia, is part of a 500 km long groundwater discharge zone, which extends from Lake Hopkins, in Western Australia, to the Finke River. In this zone, groundwater discharges and evaporates at playa surfaces over a total area of 1750 km2. Groundwater flows towards Lake Amadeus in Cainozoic sediments which overlie fractured Proterozoic bedrock.  Sediments beneath the lake bed are saturated with sodium-magnesium chloride rich brine, which contains about 250 g/L total dissolved solids. The lake bed is generally dry and contains areas of heaved gypsum ground and slightly lower, flat, halite-encrusted zones which are occasionally flooded. Gypsum is actively precipitating in the capillary zone above the water-table, which is generally at a depth of 0.30-0.50 m. In Lake Amadeus and other nearby playas the total mass of salt stored is estimated as about 6000 million tonnes and this has accumulated in about 12000 years. Water-budget calculations show that groundwater recharge in the catchment of 90 000km2 is approximately 1 mm/year, which is only 0.4 per cent of the incident rainfall.
