Heathcote Area Northern Plains, Victoria Gravity (P198141), 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 Heathcote Area Northern Plains, Victoria Gravity (P198141) contains a total of 374 point data values acquired at a spacing of 100 metres. The data is located in VIC and were acquired in 1981, under project No. 198141 for Department of Minerals and Energy (Victoria); University of Melbourne.

Carpentaria Basin (Rutland Plains,Hann River,Cooktown), QLD, 1974 (P410), 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 Carpentaria Basin (Rutland Plains,Hann River,Cooktown), QLD, 1974 survey were acquired in 1974 by the QLD Government, and consisted of 24597 line-kilometres of data at 3000m 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.

GSQ Normanton Elevation grid geodetic

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This GSQ Normanton Elevation grid geodetic is elevation data for the Normanton, Qld, 2008. This survey was acquired under the project No. 1148 for the geological survey of QLD. The grid has a cell size of 0.00083 degrees (approximately 90m).  This grid contains the ground elevation relative to the geoid for the Normanton, Qld, 2008. It represents the vertical distance from a location on the Earth's surface to the geoid. The data are given in units of meters. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

Estimation of seismic quality factor Q for Victoria, Australia

The effective quality factor Q for S wave attenuation in the Victorian lithosphere has been calculated using both the spectral ratio and coda Q methods.  The frequency range studied was 2-20 Hz, and Q was found to be frequency dependent.  A simple model has been adopted, with a low Q in the top 4 km of the crust that varies from 20 at a frequency of 1 Hz to 60 at 10 Hz.  The lower crust has a higher Q that varies from 100 at 1 Hz to 700 at 10 Hz. Empirical formulae for Q determined by linear regression of logarithmic plots of amplitude versus frequency are  Q = 20f 0.5 for the 4 km thick upper crust, and  Q = 100f 0.85 for the lower crust, where f is frequency.

Cretaceous coccoliths in the middle Eocene of the western and southern margins of Australia: evidence of a significant reworking episode

A reworking episode is indicated by occurrences of upper Cretaceous coccoliths among middle Eocene assemblages in four basins (Carnarvon, Perth, Eucla, and Otway Basins) along the Australian western and southern margins. The episode falls within the coccolith biostratigraphic interval from the lowest occurrence of Cyclicargolithus reticulatus to the highest occurrence of Daktylethra punctulata, which correlates with the foraminiferal zonal interval P.12-P,13. At the time of the episode (about 45-44 Ma) the sea advanced along the southern margin from the west, causing a transgression in the Eucla Basin and an ingression in the Otway Basin.  Coincident with this sea-level rise, and probably the cause of it, was a major acceleration in the spreading rate south of Australia. In the absence of known in-situ occurrences of upper Cretaceous coccoliths on the southern margin or offshore to the south, the Naturaliste Plateau is thought to have been the most likely provenance for the reworked taxa in the Eocene of the Eucla and Otway Basins - short-lived strong currents stripped off coccolith-rich upper Cretaceous sediments on the plateau and transported them eastward. In the Perth Basin a local source, the upper Cretaceous coccolith-rich Gingin Chalk/ Lancelin Beds, is suggested for the reworked taxa, whereas in the Carnarvon Basin a distant source is more likely.

AUSGeoid98 v.1.0 data files: (sc54-10)

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.

Vanuatu Earthquake 17 Dec 2024 land motion impact observed by GNSS

On 17th of December 2024 at 01:47:26 UTC, a magnitude 7.2 earthquake with a depth of 50 km occurred about 20 km West-North-West of Port Vila in Vanuatu1. The earthquake caused significant building damage and caused disruptions in the communication lines across the region.
A Global Navigation Satellite Systems (GNSS) Continuously Operating Reference Station (CORS), known as ‘PTVL’, operates in Port Vila, Vanuatu, as part of the International GNSS Service (IGS) network, Asia-Pacific Reference Frame (APREF) network and South Pacific Regional GNSS Network (SPRGN). The site is located at the Vanuatu Weather Service Office, Port Vila. The GNSS station is operated through funding provided by Australian Aid, under the Climate and Oceans Support Program in the Pacific (COSPPac).
This report is the preliminary ground motion analysis of this event that occurred in Vanuatu on 17 December from Global Navigation Satellite Systems data.

3D Geologic Modelling for Groundwater Applications in the Condamine headwater sub-catchments, Queensland

Geoscience Australia has developed a computer-generated 3D model which conceptualises the key
hydrogeological components of the Hodgson and Kings Creek sub-catchments in south-eastern
Queensland. These are headwater tributaries of the Condamine River, and are situated in the
agriculturally important Darling Downs region south-west of Toowoomba. Groundwater is an
important resource for rural communities and landholders in the area, and is used extensively for
crop irrigation, stock and domestic purposes, and town water supplies. Our principal objective in
building the 3D model was to help promote greater understanding and appreciation of the region's
groundwater resources among the numerous local people and communities that rely upon
groundwater, but who may not be familiar with the key concepts and principles which govern its
intrinsic behaviour. Additionally, the model can be applied by surface water and groundwater
scientists, water planners and natural resource managers to assist in the ongoing study, management
and administration of the region's important aquifer systems.
