Bulk Source Rock Database Table

The bulk source rock database table contains publicly available results from Geoscience Australia's organic geochemistry (ORGCHEM) schema and supporting oracle databases for the bulk properties of sedimentary rocks that contain organic matter and fluid inclusions taken from boreholes and field sites. The analyses are performed by various laboratories in service and exploration companies, Australian government institutions, and universities, using a range of instruments. Sedimentary rocks that contain organic matter are typically referred to as source rocks (e.g., organic-rich shale, oil shale and coal) and the organic matter within the rock matrix that is insoluble in organic solvents is named kerogen. Data includes the borehole or field site location, sample depth, stratigraphy, analytical methods, other relevant metadata, and various data types including; elemental composition, and the stable isotopes of carbon, hydrogen, nitrogen, and sulfur. Results are also included from methods that separate the extractable organic matter (EOM) from rocks into bulk components, such as the quantification of saturated hydrocarbon, aromatic hydrocarbon, resin and asphaltene (SARA) fractions according to their polarity. The stable carbon (13C/12C) and hydrogen (2H/1H) isotopic ratios of the EOM and derivative hydrocarbon fractions, as well as fluid inclusion oils, are presented in delta notation (i.e., &delta;13C and &delta;2H) in parts per mil (‰) relative to the Vienna Peedee Belemnite (VPDB) standard.

These data are used to determine the molecular and isotopic compositions of organic matter within rocks and associated fluid inclusions and evaluate the potential for hydrocarbon generation in a basin. Some data are generated in Geoscience Australia’s laboratory and released in Geoscience Australia records. Data are also collated from destructive analysis reports (DARs), well completion reports (WCRs), and literature. The bulk data for sedimentary rocks are delivered in the Source Rock Bulk Properties and Stable Isotopes web services on the Geoscience Australia Data Discovery Portal at https://portal.ga.gov.au which will be periodically updated.

Penola 1:250 000, R502 historical topographic map

The R502 series of maps has been replaced by the National Topographic Map Series (NTMS). The R502 series consists of 542 map sheets and covers Australia at a scale of 1:250,000. It was compiled from aerial photography, but only about one quarter of the series was contoured. The standard sheet size is 1 degree of latitude by 1.5 degrees of longitude. Transverse Mercator map projection and Clark 1858 datum were used. Coverage of the country was completed in 1968.

Northern Depths of the Great Barrier Reef bathymetry survey (FK200930/GA4866)

This resource includes bathymetry data acquired during the Northern Depths of the Great Barrier Reef survey on RV Falkor using its Kongsberg EM302 multibeam sonar system. The EM710 data acquired on this survey will be included in a future release.
The primary objective of the survey was to explore the Cape York Peninsula region, through geophysical mapping of the shelf edge and continental slope adjacent to the barrier reefs and around the seven detached reefs lying north of Cape Weymouth, including within the large Wreck Bay. The offshore Cape York area is considered a frontier marine region with very little multibeam data collected previously in this far northern section of the Great Barrier Reef. The survey aimed to reveal the full inventory of submarine canyons, drowned reefs and any other significant seabed features in the region.
A secondary objective was to conduct geophysical mapping of the Swain slide, an underwater landslide on the slope adjacent to the Swain Reefs in the southern Great Barrier Reef, with a headscarp about 10 km wide and a debris field extending ~20 km from the headscarp. The mapping aimed to reveal the full extent of the debris field and nature of the debris material proximal to the headscarp.
Another objective was to conduct geophysical mapping around the steeper slopes around reefs in the eastern Coral Sea Marine Park, including the Saumarez, Frederick, Kenn, Wreck and Cato Reefs. The mapping aimed to fill data gaps between existing airborne LIDAR bathymetry over the shallow reefs and previously collected multibeam data around the steeper flanks. 
To achieve these objectives, the survey extended over 47 days, leaving Brisbane, Australia on September 30, 2020 and returning to Brisbane, Australia on November 17, 2020. The voyage was split into three legs, with port calls made at Cairns and Horn Island in the Torres Strait.
Geophysical mapping involved the use of both Kongsberg EM302 and EM710 multibeam systems on the RV Falkor, typically operated in Dual Swath mode. In depths deeper than ~1200 m, the EM710 was turned off. Backscatter and water column data were also collected on both multibeam systems.
This V1 dataset contains two 64m resolution 32-bit geotiff files of the FK200930  survey area produced from the processed EM302 only bathymetry data.
This dataset is not to be used for navigational purposes.
This dataset is published with the permission of the CEO, Geoscience Australia.

Tallaringa South - Th equivalent concentration grid (AWAGS, no nasvd)

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 Geological Survey of South Australia commissioned the Gawler Craton Airborne Survey (GCAS) as part of the PACE Copper initiative. The airborne geophysical survey was flown over parts of the Gawler Craton in South Australia. The program was designed to capture new baseline geoscientific data to provide further information on the geological context and setting of the area for mineral systems (http://energymining.sa.gov.au/minerals/geoscience/pace_copper/gawler_craton_airborne_survey). 
This radiometric thorium grid has a cell size of 0.0004 degrees (approximately 42m) and shows thorium element concentration of the Tallaringa South Airborne Magnetic Radiometric and DEM Survey, SA, 2017 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2017 by the SA Government, and consisted of 146285 line-kilometres of data at 200m line spacing and 60m terrain clearance. To constrain long wavelengths in the grid, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey grid.

Community risk in Mackay: a multi hazard risk assessment

Mackay, in Central Queensland, lies about mid way between Brisbane and Cairns and with a resident population around 71,400. The Mackay urban area, which is the focus of this study, is home to around 59,000.
This study makes extensive use of Geoscience Australia's Risk-GIS method, which is a fusion of the decision support capabilities of geographical information systems, or GIS and the philosophy of risk management. The analysis of risk involves assessing the levels of hazard at Mackay, developing an understanding of the vulnerability of the elements which are at risk within the community and synthesising a range of event scenarios. A comprehensive building database is used to generate damage assessments for the various scenarios with each suburb ranked for its contribution to overall community vulnerability and for exposure to the various hazards. These two rankings determine total risk for each suburb by hazard, which allows the overall community risk from the various hazards to be compared.
