Southwest Margin Data Package

Between October 2008 and February 2009, Geoscience Australia undertook two major surveys off the coast of Western Australia.  Areas of interest included the Mentelle and northern Perth Basins, the Southern Carnarvon Basin, the southern Exmouth Sub-basin (Northern Carnarvon Basin) and the Wallaby Plateau. 
These surveys collected a range of data, including industry-standard seismic reflection data and gravity and magnetic data. 
In addition to the new data collected, Geoscience Australia has reprocessed existing open file 2D seismic data within the survey area.
These data are available for purchase. Please complete the order form on the downloadable information sheet and return to Geoscience Australia.

Unlocking Antarctica Building an open access, accessible satellite data platform

Digital Earth Antarctica is an exciting new platform that is being developed by Geoscience Australia. The platform, based on Open Data Cube technology, will enable access to corrected continental scale satellite data for all of Antarctica and its surrounding areas of sea ice. Time-series data that has been corrected and validated for Antarctic conditions will be openly accessible to users for the first time, providing a vast resource of data spanning decades. The need for monitoring and understanding change across Antarctica has never been greater with rapid changes in sea ice, ice sheets and the oceans now observed and forecast to increase over coming decades with far-reaching consequences for global climate, sea level rise, ocean circulation and dependent ecosystems. Continued satellite monitoring, and the development of infrastructure that ensures data discovery and analysis, is critical for supporting our Antarctic science capability and providing a robust basis for decision makers.

Our ability to observe Antarctica systematically at a continental scale has been constrained by difficulties accessing, storing and pre-processing satellite imagery prior to analysis. Factors such as cloud masking, reflectivity, prolonged periods of darkness, changes in atmospheric water vapour, aerosols and signal scattering mean that corrections applied to satellite data in other regions and in existing global products aren’t fully applicable to Antarctic conditions. Digital Earth Antarctica will focus on providing analysis ready optical data from Landsat and Sentinel-2 collections, as well as Sentinel-1 for synthetic aperture radar backscatter and interferometric data. Synthetic aperture radar (SAR) data over Antarctica is crucial for overcoming the challenges of sustained observing during periods of cloudiness and darkness.

This presentation will provide an overview of Digital Earth Antarctica’s planned processing pipelines to produce analysis ready optical and SAR data and the wealth of opportunities that will be unlocked to observe, monitor and understand Antarctic systems.

Installed Geothermal and Geoexchange Capacity

The Australian Geothermal Association compiled data on the installed capacity of direct-use geothermal and geoexchange systems in Australia, including large-scale ground source heat pumps and hot sedimentary applications through to December 2018. Large-scale direct-use hot sedimentary aquifer systems includes systems to heat swimming pools or provide hydronic heating systems. In geoexchange systems, the Earth acts as a heat source or a heat sink, exploiting the temperature difference between the surface (atmosphere) and at depth. The temperature of the Earth just a few metres below the surface is much more consistent than atmospheric temperature, especially in seasonal climates. These resources do not require the addition of geothermal heat.

GSNSW Exploration NSW Area U Southern Peel magnetic grid geodetic

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.
This GSNSW Exploration NSW Area U Southern Peel magnetic grid geodetic has a cell size of 0.00048 degrees (approximately 50m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2001 by the NSW Government, and consisted of 31584 line-kilometres of data at 250m line spacing and 80m terrain clearance.

AUSGeoid98 v.1.0 data files:  (sc54-04)

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.

Hierarchical classification and vector ordination in the distinction of limestones in the Fairfield Group Canning Basin, Western Australia

The existence of two Formations, the Laurel and Gumhole, in the Upper Devonian to Lower Carboniferous Fairfield Group from the Lennard Shelf in the Canning Basin has been established during field studies and confirmed using a multivariate analysis based on petrographic and geochemical data. Limestones of the Gumhole Formation are generally characterised by a dominance of either ooids or brachiopods, or the presences of bryozoa, as well as higher levels of Mn, Fe, Pb, Zn and the ratio Ca/Mg than are present in the limestones of the Laurel Formation, which are characterised by the presence of either pelecypods or silt, and higher levels of Mg, Sr, and the ratio Sr/ Ca. For the study, two representative groups of limestones from these formations were analysed. The analysis involved a taxonometric technique incorporating classification, ordination and diagnostic programs, and utilized in all 19 petrographic and 14 geochemical attributes. In both groups, at least 74 per cent of the samples were successfully differentiated on the criteria presented.

Pb-isotope data from base-metal deposits in central Australia: implications for Proterozoic stratigraphic correlations

Pb-isotope data for samples of lead-bearing minerals collected in central Australia provide useful age information, based on recently developed Pb-isotope mixing models.  The Strangways Metamorphic Complex and the Bonya Metamorphics in the Arunta Block are hosts to stratabound base-metal lodes with model Pb-ages clustered with that of vesicle-filling galena from the lower Hatches Creek Group in the southern Tennant Creek Block.  It is suggested, therefore, that these units in the northern and central Arunta Block are time-depositional equivalents of the Hatches Creek Group, the age of which has been independently established by zircon geochronology as 1820-1810 Ma. This time interval was an episode of extension, rift-style deposition and generation of volcanogenic base-metal deposits in the northern and central Arunta Block.  The model Pb-age of the Oonagalabi prospect, and hence its host, the Bungitina metamorphics, appears younger than that for the Strangways Metamorphic Complex, but field evidence requires a more complex interpretation, involving metasomatic addition of radiogenic lead. Other deposits in the northern Arunta Block have Pb-isotope characteristics that show they are younger than their host rocks, and are thus related to granite intrusion or later tectonism. Home of Bullion lead has a range of compositions that can be interpreted to indicate formation probably in the Late Proterozoic.  The isotopic composition of lead in the gold lodes of the Tennant Creek district indicates model Pb-ages consistent with introduction shortly after deposition of their host rocks, during folding and granite emplacement.
