Geology of the Officer Basin, Western Australia

This bulletin presents the results of a reconnaissance regional mapping project carried out in the Western
Australian part of the Great Victoria Desert and the southern half of the Gibson Desert (Fig. 1). In this
area a relatively thin veneer of nearly flat-lying Phanerozoic rocks overlies a thick, folded Proterozoic
sequence. The sedimentary sequences in this area are collectively referred to as forming the Officer Basin
in Western Australia. However, parts of the sequence are continuous with, or equivalent to, sequences in
adjacent basins.

Gosses Bluff Gravity (P196815), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 Gosses Bluff Gravity (P196815) contains a total of 1481 point data values acquired at a spacing between 100 and 800 metres. The data is located in NT and were acquired in 1968, under project No. 196815 for Bureau of Mineral Resources (BMR).

Relational databases for geoscience data: HYDROCHEM, a case study.

Millions of data points have been acquired or compiled through both phases of the Exploring for the Future (EFTF) program at Geoscience Australia (GA). This data that graces the EFTF Portal and appears in many publications has another home within specialist databases designed and built to house the specific data that GA collects. One such database is HYDROCHEM, which was implemented as part of the Enhanced Data Delivery (EDD) and National Groundwater Systems (NGS) projects. HYDROCHEM hosts 190,097 rows of groundwater, surface water and rainfall water chemistry analyses. This data was either previously hosted in the GNDWATER database, or compiled from legacy data stores. The redevelopment of GNDWATER to HYDROCHEM saw the de-duplication and updating of sample and site-specific metadata into other GA databases, such as SAMPLES, BOREHOLES and FIELDSITES. The redevelopment also added additional constraints to the database, including minimum metadata requirements, constrained look-up tables for units of measure, laboratory, method, filter sizes, standards and uncertainty types. Other features include minimum and maximum values for particular analytes and delivery of the data in standardised GA-preferred units of measure.

Coastal Seabed Mapping Survey, Vestfold Hills, Antarctica, February-March 2010 (AAS 2201) - Post Survey Report

From February to March 2010, Geoscience Australia (GA) conducted an multibeam survey of the coastal waters of the Vestfold Hills in the Australian Antarctic Territory. The survey was conducted jointly with Australian Antarctic Division (AAD) and the Deployable Geospatial Survey Team (DGST) of the Royal Australian Navy. The survey was aimed primarily at understanding the the character of the sea floora round Davis to better inform studies of the benthic biota and the possible impacts of the Davis Station sewage outfall. DGST were involved so the data could be used to update and extend the nautical charts of the Davis area.

Geology of the Burketown

These data are a digital representation of information depicted on the printed map of the Burketown 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.

Estimating Extreme Geoelectric Field Values for the Australian Region

There are a number of global initiatives to understand and mitigate the impacts of extreme space weather on critical infrastructure and modern society. This paper provides the results of an analysis to estimate extreme geoelectric field values for the Australian region to facilitate evaluation of Australia's power system response to extreme geomagnetic storms. Geoelectric fields are calculated using a grid of modeled magnetotelluric impedance tensors obtained from a 3‐D conductivity model of the Australian region. Statistical metrics derived from grids of geoelectric field time series are analyzed as a function of Dst index for different storm days to extrapolate geoelectric fields to extreme storm levels over a range of ground conductivity conditions. For Carrington event storm levels, geoelectric field values of 5.3 ± 3.8 V/km in the north‐south direction and 9.6 ± 4.3 V/km in the east-west direction are expected for areas of electrically resistive rocks near coastlines that are adjacent to deep highly conductive oceans, and inland, where there are large contrasts between the electrical conductivities of different rock types across Australia. Further, geoelectric field values may change by at least an order of magnitude over the grid spacing interval of 50 km in these areas. The results of the analysis also suggest that upscaling grids of geoelectric field time series derived from an observed storm by the ratio of extreme storm Dst to the observed storm Dst are a valid approach for the Australian region that provides extreme storm scenarios for different storm morphologies.

GSWA Perth Basin North TMI 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 GSWA Perth Basin North TMI Grid Geodetic has a cell size of 0.00083 degrees (approximately 87m). The units are in nanoTesla (or nT).

Maps and More: Applying Spatial Sciences to Enhance Disaster Resilience for Development in Papua New Guinea

The workshop "Maps and More: Applying Spatial Sciences to Enhance Disaster Resilience for Development in PNG" was designed as an event to bring together a broad range of actual and potential future members in the PNG disaster resilience community to discuss the application of spatial sciences for informing resilience outcomes. Importantly, it included specialists and representatives of agencies who may not have regarded themselves as important contributors of spatial data or information for disaster resilience, and it provided an opportunity to understand the potential to contribute to resilience outcomes.
The workshop commenced with a series of presentations on the meaning of spatial sciences, disaster resilience, disaster risk and impact, and how disaster preparedness and mitigation differs from response to a disaster. The role of spatial data and information as a tool for decision making was emphasised, and the variety of contributing spatial data themes was described. The difference between producer and end user of spatial data and associated products was made, and selected organisations were invited to present on how they currently produce and/or use spatial data relevant to understanding of natural hazards and their potential impacts.
