AUSGeoid98 v.1.0 data files:  (sk54-13)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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

Victoria River Downs 1 200, NT, 1998 (P1004), 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 Victoria River Downs 1 200, NT, 1998 (P1004), radiometric line data, AWAGS levelled were acquired in 1998 by the NT Government, and consisted of 90466 line-kilometres of data at 400m line spacing and 60m 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.

Galilee Basin region: Discovered resources data guide

Statements of existing knowledge are compiled for known mineral, coal, hydrocarbon and carbon capture and storage (CCS) resources and reserves in the Galilee Basin region. This data guide illustrates the current understanding of the distribution of these key resource types within the Galilee Basin region based on trusted information sources. It provides important contextual information on the Galilee Basin and where additional details on discovered resources can be found.
The Galilee Basin region contains 6 known metallic mineral deposits, with most of these containing the critical mineral vanadium. There are 17 coal deposits found in the basin containing thermal and metallurgical coal. The primary form of coal in the deposits is thermal coal. The Galilee Basin hosts large coal tonnages, with known black coal resources of approximately 33 billion tonnes.
The Galilee Basin and overlying basins are known to contain significant hydrocarbon resources. The majority of the known hydrocarbon resources are found in the Julia Creek oil shale deposits located in the Eromanga Basin above the Galilee Basin. Moderate coal seam gas (CSG) resources have also been identified in the basin; however, conventional gas resources are more limited.
At this time, there are no active or planned Carbon Capture and Storage (CCS) projects in the basin.

Detailed seismic velocity/depth models of the Upper lithosphere of the Pilbara Craton, Northwest  Australia

Detailed velocity/depth models of the crust of the Pilbara Craton have been produced from amplitude studies of refracted and reflected seismic waves and their travel-times. On three profiles, a near-surface high-velocity layer, in which the velocity sometimes reaches 6.65 km s-1, is interpreted as Hamersley Basin strata overlying the crystalline basement. The seismic velocity in the near-surface crystalline basement is about 6.0 km s-1, and increases with depth through the crust, reaching 6.1-6.2 km s-1 at 11-14 km depth. Below this , at about 15 km depth, a steeper gradient to 6.35-6.45 km s-1 defines an intracrustal seismic boundary. In the lower part of the crust, velocity gradients increase the velocity to 6.6-7.2 km s-1 . In some models, second-order velocity increases with depth are used to explain bright cusps in the data. although these could also be caused by topography on the crust/mantle boundary. The crust/mantle boundary is transitional over 4-5 km, and upper mantle (Pn) velocities range from 7.5 to 8.5 km s-1 . On one profile, a sub-Moho boundary at which the velocity increases from 8.2 to 8.35 km s-1 was recognised 14 km below the crust/mantle boundary.  Previously published seismic models of the region show lateral inhomogeneity in the crust of the Capricorn Orogenic Belt, and this complicates a quantitative analysis of the amplitudes of seismic signals recorded in the orogen. However, a qualitative analysis based on the observed amplitudes, the positions of the ray-critical cusps of the previously published models , and the gravity field suggests that , while the intracrustal boundary at about 15 km depth may be sharp, the lower crust in the orogen must have high seismic velocities (and densities) and the crustal thickness in the previous models is probably not an overestimate. Increasing metamorphic grade with depth in the Yilgarn Craton probably ensures positive velocity gradients in the crust in the craton , so that the crustal thickness in the previously published models is considered reasonable. Thus, the interpreted large difference in crustal thickness between the Pilbara Craton (approximately 30 km) and the Yilgarn Craton ( 50 km) is substantiated.

Pacific Sea Level and Geodetic Monitoring Project Levelling & GNSS Monitoring Survey Reports: Port Villa, Vanuatu, March 2019

The Australian Bureau of Meteorology (BoM), Geoscience Australia (GA) and the Pacific Community (SPC) work together on the Australian Aid funded Pacific Sea Level and Geodetic Monitoring Project (PSLGMP). The project is focused on determining the long-term variation in sea level through observation and analysis of changes in the height of the land (using Global Navigation Satellite System (GNSS) data) and changes in the sea level (using tide gauges managed and operated by the BoM. It is the role of GA and SPC to provide information about ‘absolute’ movement of the tide gauge (managed by BoM) using GNSS to continuously monitor land motion and using levelling (SPC) to measure the height difference between the tide gauge and GNSS pillar every 18 months.
Land movement caused by earthquakes, subsidence and surface uplift have an important effect on sea level observations at tide gauges. For example, a tide gauge connected to a pier which is subsiding at a rate of 5 mm per year would be observed as a rate of 5 mm per year of sea level rise at the tide gauge. Because of this, it is important to measure, and account for, the movement of land when measuring ‘absolute’ sea level variation - the change in the sea level relative to the centre of the Earth. Relative sea level variation on the other hand is measured relative to local buildings and landmass around the coastline.
Geoscience Australia’s work enables more accurate 'absolute' sea level estimates by providing observations of land motion which can be accounted for by BoM when analysing the tide gauge data.
This report provides the results of the GNSS monitoring survey &amp; high precision level survey completed between the Sea Level Fine Resolution Acoustic Measuring Equipment (SEAFRAME) tide gauge and the GNSS Continuously Operation Reference Station (CORS) in Port Vila, Vanuatu from 4th to 13th March 2019 It also provides an updated height of the tide gauge derived from GNSS time series analysis and precise levelling observations.
