Frontier basins of the west Australia continental margin: Specific surface areas of seabed sediments.

Geoscience Australia marine reconnaissance survey GA2476 to the west Australian continental margin was undertaken as part of the Australian Government's Offshore Energy Program between 25 October 2008 and 19 January 2009 using the German research vessel RV Sonne. The survey acquired geological, geophysical, oceanographic and biological data over poorly known areas of Australia's western continental margin in order to improve knowledge of frontier sedimentary basins and marginal plateaus, and allow assessment of their petroleum prospectivity and environmental significance. Four key areas were targeted: the Zeewyck and Houtman sub-basins (Perth Basin), the Cuvier margin (northwest of the Southern Carnarvon Basin), and the Cuvier Plateau (a sub-feature of the Wallaby Plateau). These areas were mapped using multi-beam sonar, shallow seismic, magnetics and gravity. Over the duration of the survey a total of 229,000 km2 (26,500 line-km) of seabed was mapped with the multibeam sonar, 25,000 line-km of digital shallow seismic reflection data and 25,000 line-km of gravity and magnetic data. Sampling sites covering a range of seabed features were identified from the preliminary analysis of the multi-beam bathymetry grids and pre-existing geophysical data (seismic and gravity). A variety of sampling equipment was deployed over the duration of the survey, including ocean floor observation systems (OFOS), deep-sea TV controlled grab (BODO), boxcores, rock dredges, conductivity-temperature depth profilers (CTD), and epibenthic sleds. Different combinations of equipment were used at each station depending on the morphology of the seabed and objectives of each site. A total of 62 stations were examined throughout the survey, including 16 over the Houtman Sub-basin, 16 over the Zeewyck Subbasin, 13 in the Cuvier margin, 12 over the Cuvier Plateau and four in the Indian Ocean. This dataset comprises total chlorin concentrations and chlorin indices measured on the upper 2 cm of seabed sediments.

Murloocoppie/Wintinna, SA, 1991 (P577), 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 Murloocoppie/Wintinna, SA, 1991 (P577), radiometric line data, AWAGS levelled were acquired in 1991 by the SA Government, and consisted of 130600 line-kilometres of data at 400m line spacing and 100m 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.

Australian petroleum accumulations report. Amadeus Basin, central Australia

Three economic (1 oil and gas/condensate, 1 gas/condensate, and 1 gas) and fourteen uneconomic (6 oil, 7 gas, and 1 oil/gas) petroleum accumulations have been discovered since 1963 in the Amadeus Basin of central Australia.
The petroleum in the Amadeus Basin mainly occupies the structural, fold- related traps within the Upper Proterozoic to Upper Ordovician marine to marginal marine clastic and evaporitic sequences.  It is believed to be of algal/bacterial origin.  The API gravity ranges from 18 to 54o for crude oils, and from 52 to 64o for condensates; gases are dry and wet.
The basin's estimated petroleum resources as at 31 December 1985 comprise 5.74 x 106m3 of oil, 1.53 x 106m3 of natural-gas liquids, and 14.93 x 109m3 of sales gas.
Production from Mereenie (oil) and Palm Valley (gas/condensate) accumulations commenced during 1984.  Up to 31 December 1985 the cumulative production from the basin stood at 156.3 x 103m3 of oil and condensate, and 44.0 x 106m3 of sales gas.  The gas/condensate is transported 146 km to Alice Springs through a 20-cm-diameter pipeline; the oil is transported 269 km to Alice Springs through a 20cm pipeline and from there by rail tankers to Adelaide refinery.  As from February 1987 gas from Palm Valley will also be transported to Darwin via a 1537-km pipeline of 35.3 cm diameter.

Severe Wind Hazard Assessment for South East Queensland - local wind hazard data

The wind hazard climate in South East Queensland is a combination of tropical cyclones, thunderstorms and synoptic storms. This dataset provides estimated average recurrence interval (ARI) or annual exceedance probability (AEP) wind speeds over the region, based on an evaluation of observational (thunderstorms and synoptic winds) and simulated data (tropical cyclones). 

The tropical cyclone wind hazard was evaluated using Geoscience Australia's Tropical Cyclone Risk Model (TCRM), which provides a spatial representation of the AEP wind speeds arising from tropical cyclones. Thunderstorm wind hazard was evaluated from analysis of observed wind gusts across South East Queensland, aggregated into a single 'superstation' to provide a single representative hazard profile for the region.

The resulting combined wind hazard estimates reflect the dominant source of wind hazard in South East Queensland for the most frequent events (exceedance probabilities greater than 1:50) is thunderstorm-generated wind gusts. For rarer events, with exceedance probabilities less than 1:200, TC are the dominant source of extreme gusts.&nbsp;

Local effects of topography, land cover and the built environment were incorporated via site exposure multipliers (Arthur & Moghaddam, 2021), which are based on the site exposure multipliers defined in AS/NZS 1170.2 (2021).

The local wind hazard maps were used to evaluate the financial risk to residential separate houses in South East Queensland.

Wind speeds are provided for average recurrence intervals ranging from 1 year to 10,000 years. No confidence intervals are provided in the data.

Earthquake Risk and Mitigation Assessment in Tasmania - A collaborative project between the Tasmanian Department of State Growth and Geoscience Australia

The project has been a collaboration between the Tasmanian Department of State Growth and Geoscience Australia, with geotechnical and geological support from Mineral Resources Tasmania (MRT) in the same Department. The project has augmented a range of information products developed by Geoscience Australia (GA) in the areas of earthquake hazard, community exposure, vulnerability and retrofit measures. These were used to assess the current earthquake risk in Tasmanian communities and the opportunities to mitigate it in the high pedestrian exposure precinct of the Hobart central business district. In augmenting the inputs to this project, Mineral Resources Tasmania has facilitated access to available geotechnical and building exposure information. Mineral Resources Tasmania has also contributed their geological knowledge of the state of Tasmania in developing the deliverables.
The outcomes of the project have been communicated at workshops convened in Hobart and Launceston. Attendees included representatives from emergency management, local government, police, fire agencies, ambulance, critical infrastructure and design professionals. Significantly, resources were identified that can inform decision making to address the risk posed by the most vulnerable, and often valuable from a heritage perspective, building type, older URM.
The hazard, scenario impact and risk products have been provided as spatial layers to support state initiatives in the Planning, Preparedness, Response and Recovery areas.
