Pilbara Block (Mt Bruce, Turee Ck, Edmund), WA, 1985 (P509), 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 Pilbara Block (Mt Bruce, Turee Ck, Edmund), WA, 1985 (P509), radiometric line data, AWAGS levelled were acquired in 1985 by the WA Government, and consisted of 27957 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.

Dynamic modelling for feasibility study of the shallow CO2 injection experiment at the CO2CRC Otway site, Victoria, Australia

A dynamic modelling study was undertaken to assess the feasibility of a planned CO2 injection experiment into a shallow fault at the CO2CRC’s Otway Research Facility. The aim was to identify key physical properties that strongly influence migration behaviour but are presently unmeasured. Two different simulators (CMG-GEM and TOUGH2) were used to model this experiment. Both simulation efforts indicate that the proposed experiment is feasible, but show the need for better data on the maximum injection pressure and the permeability distribution in the near-surface region (including the continuity of the clay layer). During the simulation with high injection rate, there could be a rapid accumulation of CO2 at the early injection stage due to the constraints of maximum injection pressure. The modelling results suggest that the dominant trapping mechanisms are likely to be free CO2 gas trapped by the upper clay layer and residual trapping. The total amount of CO2 that could be injected increased with greater injection pressure, injection rate and maximum residual gas saturation. The results suggest that dissolution of CO2 is likely to continue to increase during the injection and post-injection stages. After the CO2 injection phase, the gas was found to spread laterally within the reservoir and moved upward along the permeable grid cells at the modelled fault. A comparison between the modelling approaches suggests that if there is a desire to have CO2 migrate up the fault and reach the upper clay layer, it will be important to conduct the injection experiment at the most permeable sections of the fault and inject CO2 into a shallow high permeability layer. It is necessary to clarify whether there is an unsaturated zone beneath the clay layer as this is speculated to exist but is unknown.

eo-tides - Tide modelling tools for large-scale satellite Earth observation analysis

The `eo-tides` package provides powerful parallelized tools for integrating satellite Earth observation (EO) data with ocean tide modelling. The package provides a flexible Python-based toolkit for modelling and attributing tide heights to a time-series of satellite images based on the spatial extent and acquisition time of each satellite observation. 

`eo-tides` leverages advanced tide modelling functionality from the `pyTMD` tide prediction software, combining this fundamental tide modelling capability with EO spatial analysis tools from `odc-geo`. This allows tides to be modelled in parallel automatically using over 50 supported tide models, and returned in standardised `pandas` and `xarray` data formats for further analysis.

Tools from `eo-tides` are designed to be applied directly to petabytes of freely available satellite data loaded from the cloud using Open Data Cube's `odc-stac` or `datacube` packages (e.g. using Digital Earth Australia or Microsoft Planetary Computer's SpatioTemporal Asset Catalogues). Additional functionality enables evaluating potential satellite-tide biases, and validating modelled tides using external tide gauge data — both important considerations for assessing the reliability and accuracy of coastal EO workflows. In combination, these open source tools support the efficient, scalable and robust analysis of coastal EO data for any time period or location globally.

Archean Mafic-Ultramafic Magmatic Events Resource Package

This Resource Package contains two major products: GA Record 2009/41 and two full-colour, A0-sized map sheets (containing maps at 1:5 million, 1:6 million, and 1:3 million scales) that show the continental extent and age relationships of Archean mafic and ultramafic rocks and associated mineral deposits throughout Australia. These rocks have been assigned to twenty-six Archean Magmatic Events (AME) ranging in age from the Eoarchean ~3730 Ma (AME 1) to the late Neoarchean ~2520 Ma (AME 26).
The temporal and spatial relationships of these Magmatic Events in the Pilbara Craton, Hamersley Basin, Sylvania Inlier, Yilgarn Craton, and Gawler Craton are represented on a Time-Space-Event Chart on Sheet 1. An enlarged inset map on this sheet provides in more detail the polygon and line data of the events in the Pilbara Craton, Hamersley Basin, and Sylvania Inlier.
Sheet 2 shows the interpreted distribution and characterisation of Archean mafic-ultramafic magmatic rocks in the Yilgarn Craton. In particular, potential new areas of komatiitic rocks under cover that elsewhere in the craton host significant resources of nickel, copper, and platinum-group elements, are highlighted. Other maps on Sheet 2 summarise the nickel resource endowment and crustal neodymium model ages of various geological provinces in the Yilgarn Craton. 
These map sheets, when used in association with another recently produced map 'Australian Proterozoic Mafic-Ultramafic Magmatic Events (GeoCat 66114; published in 2008)', summarise the temporal and spatial evolution of Precambrian mafic-ultramafic magmatism in Australia. 
Record 2009/41 (Geocat 69935) is a user guide for the `Australian Archean Mafic-Ultramafic Magmatic Events' map (Geocat 69347). It compiles all the geological and geochronological data that underpins the information portrayed on the map.
The Resource Package also contains in addition to the maps and record, a spreadsheet of data that support the maps and a time-series animation summarising all the Archean Mafic-Ultramafic Magmatic Events.

Draft Environmental Geoscience Program

Community concern about changes in the earth's environment has intensified during the past decade. The Government's response is reflected in the Prime Minister's statement on the Environment, in the setting up of the Resource Assessment Commission to investigate the developmental and environmental use of resources, and in the ASTEC review of environmental research in Australia.
There is increasing recognition that science provides the framework for the protection of the Australian environment and for the responsible use of its resources.
The geosciences are vital for the understanding of the environment, the development of essential resources, and the simultaneous conservation of environmental quality and diversity.
The Government's new charter for BMR, tabled in the Senate in June 1989, recognised the need for BMR to provide the knowledge base for the resolution of environmental issues.
For BMR to respond to the increasing demand for geoscientific base line data and advice in the context of sustainable development for Australia, it needs to identify the areas of geoscience necessary to take on a new role in understanding and conserving Australian earth resources in parallel with its traditional role of guiding the development of those resources.
It is proposed that new environmental projects should be managed under a new Unit of Environmental Geoscience.
For 1989/90 the development of the program will require approximately 1% of BMR resources - in professional staff and funding. In 1990/91, expenditure should be close to 2%. For fully operational programs in 1991/92 we estimate costs will be around 5-6% of total BMR resources.

Cargelligo NSW Hydrogeological map of the Murray Basin 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.

NSW Geol Survey, (Inverell, Grafton, Maclean), 1984 (P500), 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 NSW Geol Survey, (Inverell, Grafton, Maclean), 1984 survey were acquired in 1982 by the NSW Government, and consisted of 23800 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.
