The coverage of this dataset is over the Taree region . The C3 LAS data set contains point data in LAS 1.2 format sourced from a LiDAR ( Light Detection and Ranging ) from an ALS50 ( Airborne Laser Scanner ) sensor . The processed data has been manually edited to achieve LPI classification level 3 whereby the ground class contains minimal non-ground points such as vegetation , water , bridges , temporary features , jetties etc . Purpose: To provide fit-for-purpose elevation data for use in applications related to coastal vulnerability assessment, natural resource management ( especially water and forests) , transportation and urban planning . Additional lineage information: This data has an accuracy of 0.3m ( 95 confidence ) horizontal with a minimum point density of one laser pulse per square metre. For more information on the data's accuracy, refer to the lineage provided in the data history .

We describe a new framework for quantitative bushfire risk assessment that has been produced in the Bushfire Cooperative Research Centre's (Bushfire CRC) research program. The framework is aimed at assisting state of the art fire research in Australia and fire risk managers in state and territory governments. There is a need for improved bushfire risk information to address the recommendations on bushfire risk management from the inquiries held after disastrous fires in the past decade. Quantitative techniques will improve this risk information however quantitative bushfire risk assessment is in its infancy in Australia. We use the example of calculating house damage and loss to describe the elements of the framework. The framework builds upon the well-defined processes in the Australian Risk Management standard (AS/NZS ISO 31000:2009) and the National Emergency Risk Assessment Guidelines.

In this study, two hyperspectral instruments were used on sonic-cored drillhole materials to assess the value of hyperspectral methods for hydrogeological investigations: (1) the Hylogger core scanner; and (2) the Portable Infrared Mineral Analyser (PIMA). The hylogger provides continuous coverage down the logged sonic cores in the visible to near-infrared (VNIR), short wavelength infrared (SWIR), and thermal infrared (TIR) bands. The PIMA is used on individual samples, and was used to cross-check SWIR results from the Hylogger. Further validation of the methods was carried out using XRD analysis of selected samples. The hylogging method successfully mapped the distribution of clays and oxides in both the aquitards and aquifers. The Coonambidgal Formation shallow aquifer is dominated by montmorillonite, and the Menindee Formation and Blanchetown Clay aquitard by kaolinite with lesser montmorillonite. Clay mineralogy in the Calivil Formation was strongly controlled by sedimentary facies, with muddy units predominantly kaolinite, with lesser nontronite, and clays in sandy units either kaolinite-dominant or smectite-dominant. The two clay mineral associations were also found to correlate with different hydraulic conductivity trends in the Nuclear Magnetic Resonance logging of the aquifer. The underlying Renmark Group contained mixed kaolinite and smectite. Mapping of oxide species (and Munsell colours) was also informative in terms of mapping overprinting redox zones, with goethite found to be ubiquitous in all formations. Haematite was however, detected only locally in the Calivil Formation and Renmark Group. Overall, we conclude that hyperspectral logging of drillcore is a powerful tool for use in detailed hydrogeological investigations.

The Great Artesian Basin Water Resource Assessment (the Assessment) provides an analytical framework to assist water managers in the Great Artesian Basin (GAB) to meet National Water Initiative commitments. This report presents the findings of the Assessment for the Surat region - one of four reporting regions in the Assessment, including the Surat, Central Eromanga, Western Eromanga and Carpentaria regions.

Fluid escape features and their correlation with subsurface geology have been studied in the Capel and Faust basins, offshore Eastern Australia, as part of the petroleum prospectivity assessment of these frontier basins. New high resolution 2D seismic, gravity, magnetic and multibeam bathymetry data significantly improved the geological understanding of the area through imaging of the deeper structure of sedimentary depocentres and exposure of a wide range of seafloor features. Integration of seafloor features identified on multibeam bathymetry data with subsurface fluid flow pathways interpreted from seismic data provides insights into the nature of fluid flow mechanisms and seal integrity in the Capel and Faust basins. Seafloor features identified include mega-pockmarks, polygonal faults, buried mud-volcanoes, forced-folds above saucer-shape sills, and slope failures with associated debrites along basement bounding faults. The correlation between the distributions of modern bathymetric features and subsurface fluid flow pathways indicate that fluid flow has been mainly driven by Cenozoic igneous activity. The magmatism and fluid flow activity have implications for petroleum prospectivity. Ongoing magmatism, fluid flow and fault reactivation during the Cenozoic adds to the risk of hydrocarbon charge relative to regional seal formation and structure emplacement. Hydrocarbon accumulations that may have formed within the deeper syn-rift and the pre-rift sections are less likely to have been affected by the Cenozoic magmatic and fluid flow processes and, therefore, may represent lower-risk exploration targets.

Polgons representing Hydrogeological basement (base of the Jurassic-Cretaceous sequence) units in contact with base of the Great Artesian Basin. Compiled by Bruce Radke and used in conjuction with 'Great Artesian Basin hydrogeological units directly overlying the basement (base of the Jurassic-Cretaceous sequence)' to represent the hydraulic interconnection between the Great Artesian Basin and basement units.

This database contains the monthly mean and montly long term mean fields from the NCEP/NCAR Reanalysis 1960-2000. Files contain the following data: airsfc.mon.mean.nc - surface air temperature land.nc - land/sea mask slp.mon.mean.nc - sea level pressure sst.mnmean.nc - sea surface temperature (see SST_README for more details) uwnd.mon.mean.nc - U (eastward) component of wind vwnd.mon.mean.nc - V (northward) component of wind shum.mon.mean.nc - specific humidity (this file does not contain all vertical levels, unlike the other 3-d variables) For all the above, files with 'ltm' instead of 'mean' contain the long-term monthly mean data.
