Light Hydrocarbon Geochemistry of the Vulcan Sub-Basin, Timor Sea : Rig Seismic Survey 97 : Project 121.19

In October/November 1990 the Australian Bureau of Mineral Resources (BMR) carried out an 18 day combined water column geochemical and high resolution seismic survey on the Vulcan Sub-basin region of the Timor Sea. This report presents the results of the water column geochemical (direct hydrocarbon detection or DHD) aspects of that program. During the program, 2730 km of DHD data were obtained along 44 lines over the Vulcan Sub-basin, the Ashmore Platform and the Londonderry High. Ten water bottom hydrocarbon anomalies were detected during the program. Seven of these anomalies fell into two distinct groupings, which were associated with: 
-   the Skua field and surrounding fault blocks,
-   the intersection of the NE-trending Vulcan Sub-basin/Londonderry High Boundary Zone with a prominent NW-trending transfer fault zone. 
The composition of the hydrocarbon anomalies within the Skua grouping was generally consistent with them having an oil-prone, Late Jurassic source,, and is thus compatible with the known composition of the hydrocarbons in the Skua accumulation. The composition of the other grouping was more consistent with a gas/condensate source; they may have originated from more gas prone Permo-Triassic source rocks on the edge of the Londonderry High. The remaining anomalies were all very weak, and may have been due to biogenic activity. The data indicate that the DHD technique can be useful at a prospect level within the Timor Sea (for example, it did remotely detect the Skua accumulation). The types of accumulations which are most easily detected using DHD are those with a significant gas cap, a relatively shallow (&lt;2000 m) reservoir, and faulting which extends from the reservoir horizon to near the seafloor. Furthermore, the data suggest that transfer fault zones provide important pathways for hydrocarbon migration in this region.

GSV Glenelg VIMP Vic pot tho ura totg 4band radiometric grid geodetic

This GSV Glenelg VIMP Vic pot tho ura totg 4band radiometric grid geodetic is an airborne-derived radiometric Potassium, Thorium and Uranium data over a sun shaded total count radiometric data for the Glenelg, Vic, 1995 VIMP Survey (GSV3053). 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 uranium (K), uranium (U) and uranium (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 GSV Glenelg VIMP Vic pot tho ura totg 4band radiometric grid geodetic has a cell size of 0.0005 degrees (approximately 49m). The data used to produce this grid was acquired in 1994 by the VIC Government, and consisted of 24973 line-kilometres of data at 200m line spacing and 80m terrain clearance. The grid was produced by applying the colours red to the Potassium ground concentration, green to the Thorium concentration and blue to the Uranium concentration. The colours were clipped to a 99% linear scale. These colours were transparent over a shaded Total Count. This clipping will necessarily introduce some artefacts into the ratio grids in areas of very low radioelement concentrations. The 3-band image was superposed on the sun shaded TC grid of the same survey to produce the final image.

Geology of the Galbraith

These data are a digital representation of information depicted on the printed map of the Galbraith 1:250 000 Geological Series produced by AGSO and the Geological Survey of Queensland (GSQ) in 1972 (1st edition).
Data present include geological polygons (litho-stratigraphic units), linear structural features (faults, dykes, folds, trends, lineaments etc), and point features (mines, structural points etc). Polygons have a range of attributes extracted from each individual map including unit name, age and lithological description, while lines and points are feature coded according to the AGSO publication 'Symbols Used On Geological Maps' (BMR 1989). A standard look-up table of AGSO geological codes and associated descriptions is available (see ADDITIONAL METADATA).
The data has gradually evolved from elementary CAD quality data into its present topologically structured GIS format, and hence has many imperfections and inconsistencies. Data has undergone rigorous validation and testing that includes over 80 different tests. See ADDITIONAL METADATA for more information on the data standards used.

Integrated geoscience for improved groundwater management in the Upper Darling Floodplain, New South Wales

The Darling River is the primary water source for communities on the Upper Darling River Floodplain (UDF) in arid northwest New South Wales. A 70% reduction in mean annual flow down the Darling over the past 80 years, due to droughts and over-extraction, has resulted in critical water shortages and water quality issues for communities and ecosystems. Presently there is a limited understanding of the spatial extent and controls on the occurrence of lower salinity groundwater within the surrounding Darling Alluvium; a possible&nbsp;alternative water source that is also important to groundwater-dependent ecosystems.
&nbsp;
The UDF project, part of the Australian Government’s Exploring for the Future program is working in collaboration with State partners to collect and integrate new data with existing hydrogeological knowledge. The project aims to improve the hydrogeological understanding of the region to help inform water management decisions and increase water security. A key focus of the project is the Darling Alluvium (DA)—a closed regional groundwater system comprising unconsolidated Cenozoic sediments deposited primarily by the paleo and current Darling River systems and their tributaries. Connectivity with aquifers of varying quality, within the underlying Murray and Great Artesian Basins, is also being investigated. 
&nbsp;
Integration of airborne electromagnetic (AEM), hydrometric and hydrochemical data with lithology logs and geological maps has revealed a broad trend in groundwater–surface water dynamics. In the upper reaches of the floodplain systems appear to be disconnected, while in the lower reaches losing stream conditions prevail. In the losing stream setting, resistive AEM signatures, at depths of up to 60 m below ground level and extending laterally for several hundred metres from the river, indicate a hydraulic gradient away from the river. Low salinity groundwater measured in shallow bores suggest the potential for a significant quality groundwater resource. Further investigations will improve confidence in the geometry of fresh water zones, recharge rates, connectivity with underlying saline aquifers and relationships with groundwater-dependent ecosystems.&nbsp;

AUSGeoid98 v.1.0 data files: (se57-06)

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.

Reconciling neotectonic and seismic recurrence rates in SW WA

The seismicity of the southwest corner of Western Australia has long thought to have been unusual. Everingham (1968) and Everingham and Tilbury (1972) undertook an analysis of the historical earthquake catalogue for south-western Australia, and concluded that the catalogue is complete above magnitude 4.5 since 1900, and probably since 1878. 
Michael-Leiba (1987) concluded that there was a sudden increase in seismicity around 1949. The geomorphology of the area (eg. the generally flat landscape) is not consistent with the seismicity rate for the last 40 years, which includes three scarp forming earthquakes, being typical of the seismicity over the Quaternary.

Recharge and discharge estimation in data poor areas: User guide for the recharge and discharge estimation spreadsheets and MapConnect

This project involved two phases, the first of which compiled reviews of recharge and discharge studies that have been undertaken in Australia (Crosbie et al., 2010a; O'Grady et al., 2010). It also involved preliminary identification of the parameters (climate, soils, regolith, near-surface geology, landforms, vegetation etc.) that determine recharge and discharge rates along with a review of the appropriate scale mapping approaches available for these parameters (Pain et al., 2011). The second phase of the project utilised empirical relationships derived from data collected in Phase 1 of the project in a decision tree methodology that guides the user to the most appropriate estimate for recharge/discharge given the data availability. 
This report provides detailed instruction in the use of both recharge and discharge spreadsheets and the associated GIS datasets previously made available via Geoscience Australia's MapConnect website.

Treading lightly: How geoscience is revealing human impacts in Antarctica

Antarctica conjures images of expansive white icesheets but what about the 1% not covered by ice? Though small, these exposed islands of rock are hotspots of human and animal activity. Tourism, infrastructure development, and research activities can harm these fragile environments and in the dry Antarctic climate, damage from walking and vehicle tracks can persist for years. Geoscience Australia’s landscape vulnerability project has been addressing knowledge gaps about how these environments react to disturbance by people, how they recover, and new methods to track landscape change. Through this work, GA is helping build Australia’s capability as a leader in Antarctic environmental stewardship and meet our obligations under the Antarctic Treaty System and domestic legislation.
