Southern McArthur Basin Gravity Survey 2013 (P201381), 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 Southern McArthur Basin Gravity Survey 2013 (P201381) contains a total of 6278 point data values acquired at a spacing between 2000 and 4000 metres. The data is located in NT and were acquired in 2013, under project No. 201381 for Northern Territory of Australia (Northern Territory Geological Survey).

AUSGeoid98 v.1.0 data files: Macdonald (sf52-14)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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.

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.

Towards a tectonic framework for the Gawler Craton

The tectonic evolution of the Gawler Craton is defined by two periods of tectonism both of which lead to apparent cratonisation. Megacycle 1 developed during the period 2550 Ma to 2400 Ma, and megacycle 2 tectonic events occurred from 1900 Ma to 1550 Ma. Recent research has lead to recognition of major basin(s) in the eastern and northern Gawler Craton, that formed around 1760-1720 Ma. Detritus in part was derived from a source region that has affinities with lower Willyama Supergroup sources. The role of plate margin processes in the evolution of the Gawler Craton is discussed. The St Peter Suite resembles an arc system, however sutures and even the polarity of possible subduction remain unclear. It is suggested that fertile mineralised regions are characterised by tectonic processes that lead to hydration of lower crust and upper mantle, and a tectonic regime that lead to large-scale deeply-derived fluid systems.  We need to understand which structures were active during dehydration events and where major boundaries exist in terrains. We need to image those systems geophysically, and look for crust-mantle connections where rehydration processes are likely to have occurred

Geological Cross-section of the Wessel Rise, Eastern Arafura Basin

The eastern Arafura Basin contains a sedimentary sequence over 12 km thick, comprising Mid Proterozoic, Cambrian, Ordovician, Devonian, Cretaceous and Tertiary aged sediments.
Analysis is dependant on jump correlation to the well data that occurs outside the area in the Goulburn Graben, and to the outcrop in the Wessel Islands. The thicknesses present include up to 1 km of Mesozoic, 2 to 3.5 krn of Lower Palaeozoic and over 9 km of Mid Proterozoic. The Mesozoic sequence thickens to the east, and the Palaeozoic and Proterozoic thicken to the north and northeast. Excellent source potential occurs within the Proterozoic and Lower Palaeozoic, and good potential exists for
both seal and reservoir units within the Palaeozoic. Low geothermal gradients enhance the prospectivity of the Palaeozoic in this area. Very little structuring is evident in the Phanerozoic, but a major angular unconformity is present within the Mid Proterozoic sequence.

Open source flood simulation with a 2D discontinuous-elevation hydrodynamic model

A new finite volume algorithm to solve the two dimensional shallow water equations on an unstructured triangular mesh has been implemented in the open source ANUGA software, which is jointly developed by the Australian National University and Geoscience Australia. The algorithm supports discontinuous-elevation, or 'jumps' in the bed profile between neighbouring cells. This has a number of benefits compared with previously implemented continuous-elevation approaches. Firstly it can preserve stationary states at wet-dry fronts without using any mesh porosity type treatment. It can also simulate very shallow frictionally dominated flow down sloping topography, as typically occurs in direct-rainfall flood models. In the latter situation, mesh porosity type treatments lead to artificial storage of mass in cells and associated mass conservation issues, whereas continuous elevation approaches with good performance on shallow frictionally dominated flows tend to have difficulties preserving stationary states near wet-dry fronts. The discontinuous elevation approach shows good performance in both situations, and mass is conserved to a very high degree, consistent with floating point error. 

A further benefit of the discontinuous-elevation approach, when combined with an unstructured mesh, is that the model can sharply resolve rapid changes in the topography associated with e.g. narrow prismatic drainage channels, or buildings, without the computational expense of a very fine mesh. The boundaries between such features can be embedded in the mesh using breaklines, and the user can optionally specify that different elevation datasets are used to set the elevation within different parts of the mesh (e.g. often it is convenient to use a raster DEM in terrestrial areas, and surveyed channel bed points in rivers).  

The discontinuous elevation approach also supports a simple and computationally efficient treatment of river walls. These are arbitrarily narrow walls between cells, higher than the topography on either side, where the flow is controlled by a weir equation and optionally transitions back to the shallow water solution for sufficiently submerged flows. This allows modelling of levees or lateral weirs much finer than the mesh size. 
A number of benchmark tests are presented illustrating these features of the algorithm, along with its application to urban flood hazard simulation and comparison with field data. All these features of the model can be run in serial or parallel, on clusters or shared memory machines, with good efficiency on 10s - 100s of cores depending on the number of mesh triangles and other case-specific details.
