AUSGeoid98 v.1.0 data files: Birdsville (sg54-05)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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

Application of European Macroseismic Scale - 1998 in the Asia-Pacific Region

The paper presents the application of the European Macroseismic Scale - 1998 (EMS-98) in assessing vulnerability of the building stock in the Asia-Pacific region. Two case study areas have been selected for the purpose, i.e., Muzaffarabad (Pakistan) and Padang (Indonesia) which experienced severe earthquake shaking in 2005 and 2009 respectively.  Typical building types in these areas are defined and compared to the standard construction types of the EMS-98.
The inventory of 750 buildings in Muzaffarabad was obtained from a field survey carried out after the 2005 Kashmir earthquake that struck the city and its hinterland, and subsequently updated in 2007 after conducting more surveys. The surveys documented the key building features so that the primary parameters affecting vulnerability and typical failure mechanisms could be identified. Additionally, about 520 buildings were surveyed in several other cities of Pakistan.
The inventory of 4,000 buildings in Padang was acquired from the 2009 Padang Region Damage Survey undertaken following the 2009 West Sumatra Earthquake which was supported by the Australia-Indonesia Facility for Disaster Reduction. During the survey, the building stock in Padang was classified into a schema consisting of 54 types and observed damages were categorised into 9 severities. An effort was made to map the building stock and observed damages from the survey outcomes to EMS-98 definitions.
This paper highlights the flexibility and robustness that EMS-98 offers for use outside of the European region and describes the limitations and possible improvements in the current version of the scale for global application. These include the addition of new building types (e.g., dhajji, high-set timber construction, low-set timber construction and brick veneer), inclusion of a very high vulnerability class, consideration of building vintage and storey class in vulnerability assignment and damage description for wooden structures. Treatment of subjectivity and uncertainty are the key areas requiring more attention in making improvements in EMS-98 and making it a global scale.

Mount Lyndhurst - SADME Road Gravity (P196668), 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 Mount Lyndhurst - SADME Road Gravity (P196668) contains a total of 75 point data values acquired at a spacing between 1000 and 3500 metres. The data is located in SA and were acquired in 1966, under project No. 196668 for Department of Mines and Energy South Australia (SADME).

Exploring for the Future: new U–Pb geochronology for the South Nicholson region and implications for stratigraphic correlations

Zircon and xenotime U–Pb SHRIMP geochronology was conducted on samples from the South Nicholson Basin, and western Mount Isa Orogen.  These samples were collected from outcrop and core from the Northern Territory and Queensland.  The age data indicate the South Nicholson Basin was deposited after ca 1483 Ma but deposition most likely had ceased by ca 1266 Ma; the latter age likely represents post-diagenetic fluid flow in the area, based on U–Pb xenotime data.  Geochronology presented here provides the first direct age data confirming the South Nicholson Group is broadly contemporaneous with the Roper Group of the McArthur Basin, which has identified facies with high hydrocarbon prospectivity.  In addition, geochronology on the Paleoproterozoic McNamara Group provides new age constraints that have implications for the regional stratigraphy.  The data obtained in this geochronological study allow for a comprehensive revision of the existing stratigraphic framework, new correlations and enhances commodity prospectivity in central northern Australia.

GSQ Normanton Doserate grid geodetic

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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This GSQ Normanton Doserate grid geodetic has a cell size of 0.00083 degrees (approximately 90m) and shows the terrestrial dose rate of the Normanton, Qld, 2008. The data used to produce this grid was acquired in 2008 by the QLD Government, and consisted of 115883 line-kilometres of data at 400m line spacing and 80m terrain clearance.

Groundwater salinity estimation using borehole and AEM data: a framework for uncertainty analysis

Salinity of groundwater directly affects its suitability for different uses, including human consumption, stock water, agricultural use, and mineral or energy extraction. Traditionally, direct measurements of groundwater salinity at monitoring bores that intersect an aquifer have been used to map the spatial distribution of groundwater salinity. However, drilling is a logistically and economically challenging task, and we are usually left with a sparse set of measurements from which to infer groundwater salinity over large spatial extents. Airborne electromagnetic (AEM) sounding provides a solution to this problem. This is because AEM can be flown rapidly and cost-effectively over large swathes of land, and high subsurface bulk conductivities inferred from the AEM are well correlated with groundwater salinity in porous aquifers. We present here a methodology and case study from the Keep River Plains in the Northern Territory that provides information for land and watershed managers about the confidence with which salinity can be mapped over large areas using AEM. Extensive pore fluid sampling of the saturated zone, which lies beneath the watertable, enables this workflow to be used effectively. The results provided by our method can feed into decision making while accounting for uncertainty, enabling remote communities to manage their land and water resources effectively.

Redistribution of Elements by Metamorphism

Some published studies have suggested that chemical redistribution within
the earth's crust, can take place during metamorphism. This concept is
supported indirectly by a statistical study of chemical analyses of regionally
metamorphosed rocks, and directly by - a study of two contact Metamorphic aureoles
in the Canberra 1:250,000 Sheet area. Such redistribution provides an
opportunity for segregation of original trace constituents of solid rocks, and
should be taken into consideration as a possible source of ore in metamorphic
terrains.

GSSA Andamooka ReducedToPole grid geodetic

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.
This magnetic grid has a cell size of 0.0004 degrees (approximately 41m).The data are in nanoTesla (or nT). The data used to produce this grid was acquired in 2017 by the SA Government, and consisted of 81874 line-kilometres of data at 200m line spacing and 60m terrain clearance. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey.
