The King Island scheelite mine

In the years immediately preceding the present war, 75 per cent of the world's production of tungsten concentrates came from southeast Asia; approximately 50 per cent came from China.  This production consisted almost wholly of wolfram.  With the entry of Japan into the war in 1941 and its occupation of Indo-China, Thailand and Burma, these supplies were cut off from the United Nations.  This cessation of supplies made it necessary that all countries amongst the United Nations should make intensive efforts to increase their production of tungsten ores and concentrates.  In Australia, the effort was necessary in order that as much tungsten concentrate as possible could, after domestic requirements were satisfied, be exported to Great Britain and the United States of America.   As the King Island Scheelite Mine was (and still is) the largest producer of tungsten concentrates in Australia, the possibilities of increased production from the that mine were among the first to be considered.

GSWA Menzies South 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 GSWA Menzies South Doserate Grid Geodetic has a cell size of 0.00021 degrees (approximately 22m) and shows the terrestrial dose rate of the Menzies South, WA, 2013. The data used to produce this grid was acquired in 2013 by the WA Government, and consisted of 93645 line-kilometres of data at 100m line spacing and 50m terrain clearance.

Effects of Ignoring Survey Design Information for Data Reuse

Data is currently being used, and reused, in ecological research at unprecedented rates. To ensure appropriate reuse however, we need to ask the question: “Are aggregated databases currently providing the right information to enable effective and unbiased reuse?” We
investigate this question, with a focus on designs that purposefully bias the selection of sampling locations (upweighting the probability of selection of some locations). These designs are common and examples are those that have unequal inclusion probabilities or are stratified. We perform a simulation experiment by creating datasets with progressively more bias, and examine the resulting statistical estimates. The effect of ignoring the survey design can be profound, with biases of up to 250% when naive analytical methods are used. The bias is not reduced by adding more data. Fortunately, the bias can be mitigated by using an appropriate estimator or an appropriate model. These are only applicable however, when essential information about the survey design is available: the randomisation structure (e.g. inclusion probabilities or stratification), and/or covariates used in the randomisation process. The results suggest that such information must be stored and served with the data to support inference and reuse.

Mapping Geological Storage Prospectivity of CO2 for the World's Sedimentary Basins and Regoinal Source to Sink Matching

Identification of major hydrocarbon provinces from existing world assessments for hydrocarbon potential can be used to identify those sedimentary basins at a global level that will be highly prospective for CO2 storage. Most sedimentary basins which are minor petroleum provinces and many non-petroliferous sedimentary basins will also be prospective for CO2 storage. Accurate storage potential estimates will require that each basin be assessed individually, but many of the prospective basins may have ranges from high to low prospectivity. The degree to which geological storage of CO2 will be implemented in the future will depend on the geographical and technical relationships between emission sites and storage locations, and the economic drivers that affect the implementation for each source to sink match. CO2 storage potential is a naturally occurring resource, and like any other natural resource there will be a need to provide regional access to the better sites if the full potential of the technology is to be realized. Whilst some regions of the world have a paucity of opportunities in their immediate geographic confines, others are well endowed. Some areas whilst having good storage potential in their local region may be challenged by the enormous volume of CO2 emissions that are locally generated. Hubs which centralize the collection and transport of CO2 in a region could encourage the building of longer and larger pipelines to larger and technically more viable storage sites and so reduce costs due to economies of scale.

Cooper Basin region: Groundwater conceptual model data guide

Across Australia, groundwater is a vital resource that supports and strengthens communities, culture, the environment and numerous industries.
Movement of groundwater is complicated, taking place horizontally, vertically and across different timescales from weeks to millions of years. It is affected by changes in climate, human use and geological complexities such as the type, geometry and distribution of rocks. Understanding how all these factors interact is known as a groundwater conceptual model and it is an important first step.
This groundwater conceptualisation includes the Cooper Basin and the overlying Eromanga and Lake Eyre basins as well as surface-groundwater interactions. Figure 1 shows the locations of the cross sections used to conceptualise groundwater in the Cooper Basin region. In the Cooper Basin this includes 1 aquifer in the Lake Eyre Basin, 5 aquifers in the Eromanga Basin and 1 aquifer in the Cooper Basin (Wainman et al., 2023a, b). Additional aquifers in the Permian sequence have not been included in this assessment, as they are yet to be fully investigated (Evans et al., 2020).
Confidence for each aquifer was calculated for both salinity and water levels (Gouramanis et al., 2023a, b, c). The confidence for each aquifer was added to show the overall confidence for the basin. The level of knowledge across all aquifer is moderate to low.
The groundwater conceptualisations summarises the groundwater flow and potential connectivity between aquifers. Figures also show the distribution of the aquifers and aquitards, average salinity, potential aquifer yield and confidence over an area of 50 km along the cross section lines.

Alice Springs Region - Simpson Desert North 1, NT, 2003 (P1024), 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 Alice Springs Region - Simpson Desert North, NT, 2003 survey were acquired in 2003 by the NT Government, and consisted of 52000 line-kilometres of data at 400m line spacing and 80m 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.
