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

Geoscience Australia is the Australian Government's technical advisor on all aspects of geoscience and custodian of the nation's geographic and geological data. We study the Earth's processes and apply this knowledge to address Australia's most importance economic, social and environmental challenges.

Research on fluid and melt inclusions began with the work of Sorby and Zirkel in the mid-1800s and grew very slowly for the next 100 years. Although Russian scientists began systematic study of inclusions in the 1930s, it was not until about 1960 that publications mentioning or using fluid inclusions began to increase from a few a year to the present level of about 700. Early research focused on ore deposits, first on temperatures and salinities of ore fluids and then on their stable isotopic and major element compositions. Publications using or mentioning melt inclusions began to grow somewhat later in about 1980 and have increased to today's level of about 200. Early work on melt inclusions focused on igneous rocks with an emphasis on immiscibility and volatile elements and then on rare elements. Recent research on both fluid and melt inclusions has taken advantage of single-inclusion analytical methods to investigate speciation and partitioning in both natural and experimental magmatic and aqueous systems.

This dataset is a Gocad sgrid format of The Cooper Basin 3D Map Version 2: Thermal Modelling and Temperature Uncertainty released in August 2012 (Meixner et al., 2012). The Cooper Basin 3D Map Version 2 was produced from 3D inversions of Bouguer gravity data using geological data to constrain the inversions. The 3D map delineates regions of low density within the basement of the Cooper/Eromanga Basins that are inferred to be granitic bodies. The 3D map was originally released in two Gocad formats: surfaces and a voxet. Here it is presented as an sgrid. References: Meixner, A.J., Kirkby, A.L., Lescinsky, D.T., and Horspool, N.H., 2012.

The Radiometric Map of Australia dataset comprises grids of potassium, uranium, and thorium element concentrations, and derivatives of these grids, that were derived by seamlessly merging over 550 airborne gamma-ray spectrometric surveys in the national radioelement database

The 1:250 000 scale geological map series now covers almost all of Australia and has been produced over many years by AGSO and its counterpart state bodies. The quality of maps has improved steadily over the years. Modern maps are produced with the aid of satellite images and aircraft-obtained magnetic and gamma-ray images.

This data is a collection of data used to create the NATMAP 1:30,000k general reference map of Christmas Island.

Coal Seam Gas (CSG) activities will have an impact on groundwater. But what will be the magnitude, extent and timing of that impact? Faced with this question, and in the absence of comprehensive datasets, groundwater professionals are unable to respond with confidence. CSG activities, with some notable exceptions, are mostly carried out in stratigraphic units far below, or at a lateral distance from, those monitored by existing groundwater monitoring networks. How then can groundwater experts advise regulators and industry appropriately as to the likelihood and nature of impacts to groundwater from CSG activities? Commonwealth approval conditions for the development of CSG projects in the Surat Basin are empowered by the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) as it pertains to the protection of Matters of National Environmental Significance (MNES) including springs that host EPBC-listed threatened species and communities. The projects are approved on the basis that there will be no significant impact to MNES. The approval conditions include the requirement for regional monitoring of groundwater levels and quality for the early detection of impacts to springs. In the absence of sufficient time series data that would support sophisticated modelling, the predictive power of simple groundwater flow calculations, together with regional groundwater models, may be deployed to evaluate the envelope of magnitude, extent and timing of groundwater responses. It is proposed that these same tools may be used to develop both monitoring networks and triggers for remedial action that can adapt to increased data availability and changing production scenarios and take account of the inertia in both the physical response within the groundwater system and the institutional response from either the regulator or industry. This will facilitate the protection of groundwater-dependant ecosystems through timely and adaptive management responses whilst ensuring that CSG projects are neither injudiciously promoted, nor prematurely curtailed, through lack of monitoring data or through misinterpretation of changes in those data. This abstract was developed for the International Association of Hydrogeologists Congress, Perth, 2013 based on work undertaken for Department of Sustainability, Environment, Water, Population and Communities.
