Orroroo 1:250 000 topographic map

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD. Projection: Universal Traverse Mercator (UTM) Medium: Paper, flat and folded copies.

Geophysical Technique Mix to Resolve Offshore Basement Problems

The basement beneath Australia's offshore basins was the cradle for sediments involved in oil and gas formation. Knowledge of basement depth, boundaries and evolution provides clues to the petroleum potential of Australia's sedimentary basins. 
The problem is finding the right combination of geophysical techniques to define basement offshore, and knowing what adjustments to make to reduce unwanted effects in definition.
Geoscience Australia's Alexey Goncharov outlines his team's exciting new basement and crustal studies that are tackling the problems.

Results for calibration of Sentinel-1A using the Australian corner reflector array

Geoscience Australia has permanently deployed 40 trihedral corner reflectors in Queensland, Australia, covering an area of approximately 20,000 km2. The array of corner reflectors was constructed as part of the AuScope Australian Geophysical Observing System (AGOS) initiative to monitor crustal deformation using Interferometric Synthetic Aperture Radar (InSAR) techniques. The array includes 34 corner reflectors of 1.5m, 3 reflectors of 2.0m and 3 reflectors of 2.5m inner leg dimensions. Through the design process and the precision manufacturing techniques employed, the corner reflectors are also highly suitable for calibration and validation of satellite-borne Synthetic Aperture Radar (SAR) instruments.
Nine of the 1.5m corner reflectors in the AGOS array had their Radar Cross Section (RCS) individually characterised at the Defence Science and Technology Organisation¿s outdoor ground reflection range, prior to permanent deployment in Queensland.  The RCS measurements for the corner reflectors were carried out at X and C-band frequencies for both horizontal and vertical transmit-receive polarisations, and at a range of elevation and azimuth alignments. 
The field performance of the AGOS corner reflectors has been studied using SAR data from a range of satellites including Sentinel-1A. This study focuses on the calibration of the Sentinel-1A satellite presenting results from exercises undertaken both at Geoscience Australia and the European Space Agency¿s Mission Performance Centre as part of the satellite commissioning and routine phases. Radiometric calibration results in conjunction with geometric calibration and validation results for Sentinel-1A products from Stripmap and Terrain Observation with Progressive Scans (TOPS) modes are presented in this paper.
The current configuration for most corner reflectors in the AGOS array is set to serve calibration requirements for a broad range of SAR missions on ascending orbital passes. However, the design allows for mission-specific corner reflector alignment if needed, as in the case of the 2.5m and 2.0m reflectors which have specifically been aligned to support calibration of the L-band SAR instrument on ALOS-2.  Results reported in this paper could inform the need for re-configuring one or more corner reflectors in the array to specifically support ongoing calibration of the Sentinel-1A and B satellites.
The permanently deployed AGOS corner reflector infrastructure presents an opportunity for independent calibration and comparison of SAR instruments on current and future satellite missions, and is considered an important Australian contribution to the global satellite calibration and validation effort.

Elkedra 1, NT, 1999 (P1006), 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 Elkedra 1, NT, 1999 (P1006), radiometric line data, AWAGS levelled were acquired in 1999 by the NT Government, and consisted of 121182 line-kilometres of data at 400m line spacing and 60m 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.

Geology and hydrology, Alice Springs Town and Inner Farm Basins, Northern Territory

The Alice Springs Town Basin is a small basin filled with Quaternary alluvium, which has provided the town with water. The Inner Farm Basin is more complex, with aquifers in unconsolidated deposits of Quaternary and Tertiary age, and in Precambrian rocks. They provide groundwater for domestic and agricultural use. The results of a geophysical survey were used to plan three drilling programmes which were undertaken to investigate the occurrence of groundwater and to construct production bores for the town water supply. Several methods have been tried to construct efficient bores. The two basins contain groundwater of nine different chemical types; groundwater suitable for domestic use occurs in the vicinity of the Todd River.

Storm Tides

Historical settlement patterns have resulted in Australia having most of its major city developments situated on the coastline. Storm tides are a major natural hazard for coastal regions. Severe storms and cyclones contribute 29 per cent of the total damage cost from natural hazards to the Australian community. In 1999 prices, this amounts to A$40 billion during the period 1967 to 1999 (including the cost of deaths and injuries).
A storm surge is an increase in coastal water levels well above the normal high tide. If the storm surge is combined with daily tidal variation, the combined water level is called the storm tide. When the resulting storm tide exceeds the normal tidal range, local beach topography will dictate whether significant coastal inundation will occur.

Northeast Pilbara geological digital data. Digital geology of Marble Bar, Port Hedland, Nullagine and Yarrie

These data are a digital representation of information depicted on printed maps from the Australia 1:250, 000 Geological Series produced by AGSO and the Geological Survey of Western Australia (GSWA) between 1972 and 1982.  The data are gridded according to the standard Australian 1:250, 000 sheet breakup.  The complete dataset is comprised of the 4 1:250, 000 sheets covering marble Bar, Nullagine, Yarrie and Port Hedland in Western Australia.
Data present include geological polygons (stratigraphic units), linear structural features (faults,
dykes, folds, trends, lineaments etc).
Polygons have a range of attributes extracted from each individual map including unit name, age and lithology, 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 descriptions is available.  Pilbara Data has gradually evolved from elementary 'CAD' quality data into its present topologically structured GIS format, and hence has many imperfections and inconsistencies.  The spatial accuracy of data from some older maps is particularly problematical.  Data has undergone only moderate checking.  These map sheets were originally compiled on poor topographic bases.  For a more accurate coverage of geology, use the adjusted digital version.

AUSGeoid98 v.1.0 data files:  (sc50-13)

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.

Neoproterozoic and Cambrian chemostratigraphic mega-sequences of the Officer Basin; a regional framework to assist petroleum and mineral exploration

Well and seismic correlation schemes exist for the Western Australian and South Australian parts of the Officer Basin but there are inconsistencies between the western and eastern regions. Hence, as part of the Exploring for the Future Officer-Musgrave Project, a chemostratigraphic correlation has been determined for the sedimentary fill of the Officer Basin with emphasis on Neoproterozoic to Cambrian rocks. The correlations have been developed on whole rock inorganic geochemical data obtained from the analysis of 10 study wells which span the basin from Western Australia and into South Australia. A total of 8 chemostratigraphic mega-sequences (MS) are recognised across the basin, that in turn are subdivided into a total of 24 chemostratigraphic sequences. MS1 to MS6 include the Neoproterozoic to Cambrian sedimentary rocks and are the focus of this study. The Neoproterozoic–Cambrian mega-sequences MS1 to MS4 broadly correspond to the previously defined Centralian supersequences CS1 to CS4 and provide robust well-control to the regional seismic correlations. Confidence in the correlation of these old rocks are important since they contain both potential source and reservoir rocks for petroleum generation and accumulation. MS7 is equivalent to the Permian Paterson Formation, while MS8 is equivalent to the Mesozoic section. The elemental data has also been used to elucidate aspects of the petroleum system by characterising reservoirs and identifying fine-grained siliciclastics deposited in anoxic environments which may have source potential. This work is expected to further improve geological knowledge and reduce the energy exploration risk of the Officer Basin, a key focus of this program.

Australia's Identified Mineral Resources 2010

Australia's Identified Mineral Resources 2010 presents estimates of Australia's mineral resources at end of December 2009 for all major and several minor mineral commodities (Table 1) based on published and unpublished data available to Geoscience Australia. These resource estimates provide a long term view of what is likely to be mined.  They are compared with national totals of ore reserves for each commodity, which provides the industry view of what is likely to be mined in the short to medium term.  Mine production data are based on figures from the Australian Bureau of Agricultural and Resource Economics and Sciences.  World ranking of Australia's mineral resources have been calculated mainly from information in publications of the United States Geological Survey.  A summary of significant industry developments also is presented.  
Australia's Identified Mineral Resources 2010 provides information on and analysis of mineral exploration expenditures in Australia for 2008-09 and the calendar year 2009.  Trends in expenditure are presented and discussed.
