Duketon total count grid geodetic

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 terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This Duketon total count grid geodetic has a cell size of 0.00083 degrees (approximately 87m) and shows the terrestrial dose rate of the Duketon, WA, 1994. The data used to produce this grid was acquired in 1994 by the WA Government, and consisted of 47160 line-kilometres of data at 400m line spacing and 80m terrain clearance.

Booligal NSW Hydrogeological map of the Murray Basin series 1:250 000

The objectives of hydrogeologically mapping the Murray basin were to generate a set of maps at 1:250 000 scale to: 

show the influence of groundwater on land salinisation and surface water salinity 
delineate useable groundwater resources 
highlight present and potential salinity hazard and 
enhance community awareness and understanding of groundwater systems and processes 

and provide a groundwater data-base for the Murray Basin to facilitate land and water resource management decisions. 
The production of the Murray Basin Hydrogeological Map Series was a major coordinated Government action in the management of groundwater to combat degradation through salinisation and enable sustainable land and water use in the Murray Basin.  The Hydrogeological Map Series was a collaborative effort between the various water authorities of South Australia, Victoria and New South Wales. 
Explaining this product in detail is an article by Evans, W.R. 1992, "The Murray Basin Hydrogeological Map Series", Water pp. 20-23.

Medium Resolution Satellite Imagery of Australia from DMCii

The Disaster Monitoring Constellation (DMC) is a constellation of satellites (presently eight) owned by various countries; operating together to provide frequent observations of the Earth for monitoring natural disasters.
The DMC satellites operate in the visible to near-infra-red part of the spectrum, which makes them very useful for crop and forest monitoring as well as general earth observation.
DMC satellites have been used in emergency response in Australia, providing daily images of the progress of floods through Queensland and New South Wales during the February 2012 flood event.
DMC imagery is also used to augment data acquired from the Landsat series of satellites. The DMC SLIM-6-22 sensor has a slightly higher spatial resolution of 22 metres and a higher revisit rate of four days; compared to Landsat 5 TM sensor with a spatial resolution of 30 metres and a revisit rate of 16 days. In addition the dual sensor layout on the satellites allows a 620 kilometre wide swath to be acquired in a single pass. DMC satellites have three spectral bands: green, red and near infra-red; where seven bands are available from Landsat 5 TM data.
Comparisons of the current generation of DMC satellites with Landsat-7 ETM+ have demonstrated that the calibration accuracy is within 1 - 3%. To maintain the calibration the DMC satellites are routinely cross-calibrated with Landsat-7 ETM+.
Landsat-5 was a key source of imagery throughout the world; until the acquisitions of imagery was suspended in 2011. To address the shortfall in access to medium resolution data, Geoscience Australia has acquired large regional coverage of DMC data from DMC Imaging International (DMCii). This acquisition will help to address monitoring needs until Landsat-8 imagery is available in mid-2013.

Mitigation of Residential Wind Risk in South East Queensland

The region of coastal South East Queensland (SEQ) represents a large concentration of population, business activity and infrastructure that is important to the economy of Queensland and Australia. The region is also subject to severe storms that can generate damaging winds, particularly as a result of thunderstorm and tropical cyclone activity. This risk posed by severe wind is not well understood, nor are the optimal strategies for managing and potentially reducing this risk.
The Severe Wind Hazard Assessment for South East Queensland (SWHA-SEQ) project has had the central objectives to gain an improved understanding of the current wind risk in this region and to develop actionable information that could inform future strategies to manage and reduce this risk. It has also included other related issues associated with future climate, strata title vulnerability, the implications of strong growth in the region and the identification of places of last resort. The project has had fifteen partners that have included local government, insurance, emergency management, State government more broadly and the research community. The two-year project commenced in October 2020 and was completed in December 2022.
This paper presents a summary of part of the research undertaken along with the outcomes in the areas of wind hazard, residential exposure definition, house vulnerability assessment, risk and mitigation. Key findings are summarised and their implications in the areas of the spatial variability of risk across the region, mitigation of vulnerability at property level, and the effectiveness of prioritised retrofit in the region.

Phosphatic organisms and the correlation of Early Cambrian carbonate formations in central Australia

Phosphatic and phosphatised organisms, mainly elements of multisclerite forms, tubes, and inarticulate brachiopods, have been found in predominantly dolostone formations in three widely separated areas of central Australia: the eastern Amadeus Basin, and the Huckitta and Marqua-Hay River regions of the Georgina Basin.  The faunas are of similar composition and age in the three areas, and permit lithological correlation of the Todd River Dolomite, the Errarra Formation, and the Red Heart Dolomite of each area, respectively. They also permit correlation with the more diversely fossiliferous sequences of the Flinders Ranges of South Australia, and indicate that these may be younger than previously thought.

Geomorphic and habitat mapping of submarine canyons of the Australian continental margin

Submarine canyons inﬂuence oceanographic processes, sediment transport, productivity and benthic biodiversity from the continental shelf to the slope and beyond. The relative inﬂuence of an individual canyon on these processes will, in part, be determined by its form, shape and position on the continental margin. Based on the latest bathymetry data for the Australian margin, we have mapped 753 submarine canyons and derived a large number of geomorphic metrics based on canyon form, shape and position. In this presentation we highlight key results, which show that these canyon metrics describe a wide variety of canyon form and physical complexity that is consistent with the geological evolution of the Australian margin and the local inﬂuence of geological and geomorphological processes. Thus, Australian submarine canyons cluster in the east, southeast, west and southwest where the margin is steepest and continental shelf is narrow. Subsequently, we used 22 environmental variables (including many of the geomorphic metrics) as surrogates to derive estimates of habitat potential for these submarine canyons. Our analysis shows that the high geomorphic and oceanographic diversity of Australian submarine canyons creates a multitude of potential habitat types, notably for benthic infaunal and epifaunal communities. Canyons with particularly high benthic habitat potential are located mainly offshore of the Great Barrier Reef and the New South Wales coast, on the eastern margin of Tasmania and Bass Strait, and on the southern Australian margin. Many of these canyons have complex bottom topography, are likely to have high primary and secondary production, and have less potential for sediment disturbance due to bottom current. Canyons that incise the shelf tend to score higher in habitat potential than those conﬁned to the slope. This habitat potential is exempliﬁed by Perth Canyon, a large shelf-incising canyon on the southwest Australian margin, which we present in this talk as a case study. High-resolution (20m) multibeam sonar data for the canyon reveals the geomorphic complexity characterised by escarpments, transverse ridges, large-scale mass movements and active bedform ﬁelds. This geodiversity and the interaction of the Perth Canyon with regional oceanographic currents (the Leeuwin Current and Undercurrent) provide highly diverse habitats for benthic fauna such as deep-sea corals and sponges and a variety of pelagic fauna including cetaceans (e.g., Australian pygmy blue whales, minke whales, sharks and tunas).
