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

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.

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.

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

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 measured in km/h.

This metadata encompasses shape files found in the "geological" directory on the CD-ROM. They are as follows:- sedimentary_basins.shp The dataset provides outlines and names of a clipped region of Australian sedimentary basins and sub-basins onshore and offshore, in the Bass Straight region (see Geographic Extent Polygon). They were compiled as part of Geoscience Australia marketing activities aimed at encouraging further exploration of Australian oil and gas reserves. techtonics.shp This dataset is a spatial representation of a database of the Tectonic Elements of the Australian region (clipped to mentioned Polygon Coordinate String), based on Geoscience Australia interpretations of existing datasets and on other published information. The database is under constant development as Geoscience Australia carries out new interpretations. basin_elements.shp These data contain interpreted basin bounding faults and basin hinges for the Bass and Durroon Basins. Fault and hinge interpretations have been based on Geoscience Australia's seismic, magnetic, and gravity datasets. Basin bounding Faults define major structures that in seismic data were interpreted to have been active during basin forming deformation. Basin Hinges define hinge lines where syn-basin tectonic structures and sedimentation make way for post-basin tectonic structures and sediment infill. Basin hinges have also been marked along areas of significant stratigraphic thinning and some volcanically dominated areas.
