Mapping of Australian Fire Weather Potential

Wildfires are one of the major natural hazards facing the Australian continent. Chen (2004) rated wildfires as the third largest cause of building damage in Australia during the 20th Century. Most of this damage was due to a few extreme wildfire events. For a vast country like Australia with its sparse network of weather observation sites and short temporal length of records, it is important to employ a range of modelling techniques that involve both observed and modelled data in order to produce fire hazard and risk assessment products with utility. This paper details the use of statistical modelling of both observations and climate model simulations (downscaled gridded reanalysis information) in the development of extreme fire weather potential maps.
Indicators of fire weather potential such as the McArthur Fire Forest Danger Index (FFDI) are widely used by fire management agencies to assess fire weather conditions and issue public warnings. FFDI is regularly calculated at weather stations using measurements of weather variables and fuel information. As it has been shown that relatively few extreme events cause most of the impacts, the ability to derive the spatial distribution of the return period of extreme FFDI values contributes important information to the understanding of how potential risk is distributed across the continent. 
The long-term tendency of FFDI has been assessed by calculating the return period of its extreme values from point-based observational data using extreme value distributions. The spatial distribution of the return period of FFDI was obtained by applying an advanced spatial interpolation algorithm to the measurements made at weather stations.  As an illustration, maps of 50 and 100-year return period of FFDI under current climate conditions are presented (based on both observations and reanalysis climate model output).

Metamorphic Evolution and Integrated Terrane Analysis of the Eastern Yilgarn Craton: Rationale, Methods, Outcomes and Interpretation

A metamorphic database covering the entire eastern Yilgarn Craton has been compiled from pre-existing mapping, 14,500 sites with qualitative metamorphic information, and 470 new key sites with detailed quantitative metamorphic data including P, T, temperature/depth ratio and P-T paths. The derived temporal and spatial patterns contrast with previous tectonic models and invariant crustal depth with the single prograde metamorphic event of the long-standing metamorphic paradigm. In particular, there are large variations in peak metamorphic crustal depths (12 to 31 km), and five metamorphic periods can now be recognised.
&#149;  Ma:     Very localised, low-P granulite of high temperature/depth ratio (&gt;50ÂºC/km).
&#149;  M1:     High-P (8.7kb), low temperature/depth ratio (&lt;20ÂºC/km) assemblages localised to major shear zones with clockwise isothermal decompression P-T paths.
&#149;  M2: Regional matrix parageneses with T ranging 300-550ÂºC across greenstone belts and elevated temperature/depth ratio of 30-40ÂºC/km throughout. Tight clockwise paths evolved through maximum prograde pressures of 6 kb and peak metamorphic pressures of 3.5-5.0 kb.
&#149;  M3a: An extension related thermal pulse localised on the Ockerburry Fault and post-volcanic late basins. Anticlockwise paths to peak conditions of 500-580ÂºC and 4.0 kb, define moderately high temperature/depth ratio of 40-50ÂºC/km.
&#149; M3b: Multiple localised hydrothermal alteration events during a period of exhumation from 4 kb to 1 kb.
Metamorphic patterns during each event have been temporally and spatially integrated with the new deformation framework (Blewett &amp; Czarnota, 2007c) by a process of metamorphic domain analysis and using metamorphic field gradients. The continual evolution with time of fundamental metamorphic parameters throughout the entire history have been constructed as evolution curves and integrated with the deformation, magmatic, stratigraphic and mineralization history.

AUSGeoid98 v.1.0 data files:  (sl54-02)

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.

Nobjuno Detailed Gravity Survey, NT (P199216), 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 Nobjuno Detailed Gravity Survey, NT (P199216) contains a total of 332 point data values acquired at a spacing between 40 and 800 metres. The data is located in NT and were acquired in 1992, under project No. 199216 for None.

GSWA Devils Creek Doserate 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.

Landscape evolution and tectonics in southeastern Australia

Rivers flowing north and west across southeastern Australia are older than the formation of the eastern continental margin and the Murray Basin. In the Jurassic and most of the Cretaceous, Australia was bound by land to the east (Pacifica), from which rivers carried sediment to the Eromanga-Surat Basin. The Otway-Gippsland Basin, bound to the north by the Victoria Divide, accumulated sediment from the early Cretaceous. At about 80 Ma, tectonic rifting along the line of the present continental shelf cut off the headwaters of Australian rivers then rising in Pacifica, beheading many rivers and reducing the sediment supply to the sedimentary basins. The input of coarse fluvial sediment to the Eromanga-Surat Basin ceased, but was maintained to the Otway-Gippsland Basin. In the Palaeocene, the Murray Basin started to sink, creating a divide between the Murray and Eromanga-Surat Basins and cutting off the southern sediment supply to the latter. Down-warping along the Tasman Sea margin formed the Great Divide between Tasman Sea drainage and the inland sedimentary basins. Rivers east of this divide were reversed, and a Great Escarpment was formed which retreated inland. Cainozoic volcanicity and Miocene faults with throws of hundreds of metres have further complicated the topography. The history derived from the study of river development and the evolution of major divides is paralleled by that of basin sedimentation. Basin down-warping formed the major divides, and led to the erosional development of the present landscape .
