The Surface Hydrology Points (Regional) dataset provides a set of related features classes to be used as the basis of the production of consistent hydrological information. This dataset contains a geometric representation of major hydrographic point elements - both natural and artificial. This dataset is the best available data supplied by Jurisdictions and aggregated by Geoscience Australia it is intended for defining hydrological features.

Geoscience Australia carried out a marine survey on Carnarvon shelf (WA) in 2008 (SOL4769) to map seabed bathymetry and characterise benthic environments through colocated sampling of surface sediments and infauna, observation of benthic habitats using underwater towed video and stills photography, and measurement of ocean tides and wavegenerated currents. Data and samples were acquired using the Australian Institute of Marine Science (AIMS) Research Vessel Solander. Bathymetric mapping, sampling and video transects were completed in three survey areas that extended seaward from Ningaloo Reef to the shelf edge, including: Mandu Creek (80 sq km); Point Cloates (281 sq km), and; Gnaraloo (321 sq km). Additional bathymetric mapping (but no sampling or video) was completed between Mandu creek and Point Cloates, covering 277 sq km and north of Mandu Creek, covering 79 sq km. Two oceanographic moorings were deployed in the Point Cloates survey area. The survey also mapped and sampled an area to the northeast of the Muiron Islands covering 52 sq km. cloates_3m is an ArcINFO grid of Point Cloates of Carnarvon Shelf survey area produced from the processed EM3002 bathymetry data using the CARIS HIPS and SIPS software

This survey was undertaken as part of a research porgram within the Torres Strait CRC aimed at understanding marine biophysical processes in Torres Strait and their effect on seagrass habitats. This is the second of 2 Geoscience Australia surveys undertaken as part f the program. Data collected on the survey includes sediment samples, suspened solids samples, multibeam, and oceangrahic current data.

This use of this data should be carried out with the knowledge of the contained metadata and with reference to the associated report provided by Geoscience Australia with this data (Reforming Planning Processes Trial: Rockhampton 2050). A copy of this report is available from the the Geoscience Australia website (http://www.ga.gov.au/sales) or the Geoscience Australia sales office (sales@ga.gov.au, 1800 800 173). This file identifes the storm tide inundation extent for a specific Average Recurrence Interval (ARI) event. Naming convention: SLR = Sea Level Rise s1a4 = s1 = Stage 1(extra-tropical storm tide), s2 = Stage 2 (tropical cyclone storm tide) (relating to Haigh et al. 2012 storm tide study), a4 = area 4 and a5 = area 5 2p93 = Inundation height, in this case 2.93 m Dice = this data was processed with the ESRI Dice tool.

This data release includes a three-dimensional (3D) geological map of the Cooper Basin region which has been produced from 3D inversions of Bouguer gravity data using geological data to constrain the inversions. It also includes predictions of temperature and temperature uncertainty which have been produced from the 3D map. The 3D geological map delineates regions of low density within the basement of the Cooper and Eromanga basins. These are inferred as granitic bodies, which may act as heat sources. It also delineates the stratigraphy of the sedimentary basins which provide thermal insulation. This release is the second version of the 3D map of the Cooper Basin region. It builds on Version 1 of the Cooper Basin Region Geological map, released in 2009. The 3D map is supplied in Gocad® format as a voxet. The voxet contains the following properties: Geology - defined as lithology number (integer) corresponding to each geological unit in the 3D map: 0 - Air 1 - Surficial 2 - Allaru 3 - Cadna-owie 4 - Westbourne 5 - Nappamerri 6 - Toolachee 7 - Patchawarra 8 - Tirrawarra 9 - Warrabin Trough 10 - Basement (central) 11 - Undifferentiated granite 12 - Big Lake Suite granodiorite 13 - Devonian granite 14 - Basement (northwest) 15 - Basement (southeast) Heat_Flow - Predicted heat flow (in mW/m2) throughout the volume of the map Heat_Production_Rate - input heat production rate (in W/m3) assigned to each geology unit Temperature_degC - predicted temperature in degrees celcius throughout the volume of the map Temperature_Standard_Deviation_degC - standard deviation on the temperature predictions Temperature_Standard_Deviation_percent - standard deviation on the temperature predictions, calculated as a percentage of the predicted temperature Thermal_Conductivity - final thermal conductivity values (W/mK), calculated at the modelled temperature.

The wind hazard outputs are a series of rasters, one for each average recurrence interval considered, presenting peak wind hazard (peak from all directions) as measure in km/h. This file identifies the extent of inundation from sea-level rise combined with Highest Astronomical Tide (HAT) which is 3.9 m AHD. The name of the file indicates the scneraio water height, e.g. p3p9_LGAClip indicates the inundation shown is for 3.9 m above AHD and that the file has been clipped by the Local Government Area (LGA) to remove the offshore inundation identified.

Geoscience Australia carried out marine surveys in Jervis Bay (NSW) in 2007, 2008 and 2009 (GA303, GA305, GA309, GA312) to map seabed bathymetry and characterise benthic environments through colocated sampling of surface sediments (for textural and biogeochemical analysis) and infauna, observation of benthic habitats using underwater towed video and stills photography, and measurement of ocean tides and wavegenerated currents. Data and samples were acquired using the Defence Science and Technology Organisation (DSTO) Research Vessel Kimbla. Bathymetric mapping, sampling and tide/wave measurement were concentrated in a 3x5 km survey grid (named Darling Road Grid, DRG) within the southern part of the Jervis Bay, incorporating the bay entrance. Additional sampling and stills photography plus bathymetric mapping along transits was undertaken at representative habitat types outside the DRG. darlingrd_1m is an ArcGIS layer of the backscatter grid of the Darling Road survey area produced from the processed EM3002 and EM3002D backscatter data of the survey area using the CMST-GA MB Process

These colour and greyscale images are digital pictorial representations of the grid of the Magnetic Anomaly Map of Australia (third edition). This grid was compiled from 9 million line-kilometres of TMI data held in the National Airborne Geophysics Database. The data were collected in surveys conducted by AGSO (formerly the Bureau of Mineral Resources, Geology and Geophysics (BMR))and by airborne geophysical companies operating under contracts to AGSO and State and Territory Geological Surveys, either separately or in joint projects. Data from a number of other surveys, carried out for private companies, were acquired by AGSO. These images contain anomalies with wavelengths as small as 3200 m. The original grid data with a cell size of 15 seconds of arc (about 400m) used for the preparation of these images are available from AGSO in digital form for the whole continent, and on an individual 1:1 000 000 sheet area basis. Point located data are available on a survey basis.

The data represents the possibility that the substrate is rocky. It was created from the averaged topographic relief layer. The data values range from 0 to 100.
