Ground Penetrating Radar (GPR) Data - Adelaide Metropolitan Beaches Survey

This record contains processed and topographically corrected Ground Penetrating Radar (GPR) data (.segy, .bmp), and a summary shapefile collected on fieldwork at  Adelaide Metropolitan Beaches, South Australia for the Bushfire and Natural Hazards CRC Project, Resilience to Clustered Disaster Events on the Coast - Storm Surge. The data was collected from 16-19 February 2015 using a MALA ProEx GPR system with a 250 MHz shielded antennae. The aim of the field work was to identify and define a minimum thickness for the beach and dune systems, and where possible depth to any identifiable competent substrate (e.g. bedrock) or pre-Holocene surface which may influence the erosion potential of incident wave energy. Surface elevation data was co-acquired and used to topographically correct the GPR profiles. This dataset is published with the permission of the CEO, Geoscience Australia.

Murray Basin Hydrogeological project : progress report 13 for half year ending 31 March 1985

At Bureau of Mineral Resources, Project staff concerned with the geological phase have devoted much effort to checking and editing bore hole stratigraphic data and in compiling a report on the subsurface stratigraphic database; these tasks have proceeded in parallel with the computer-assisted drawing of structure contour maps of stratigraphic units and aquifers. The cartographic work, together with the writing of a text on the geology of the Basin, is continuing. A preliminary edition of a 1:1 million scale Cainozoic geology map of the Basin was published in February. Work on the hydrogeological aspects of the Project continued with the compilation of data from four 1/4 million scale map sheets, and some water sampling in previously little known areas.

Isa-Georgetown Block B, QLD, 2000, Prospectivity Plus Initiative (P827), radiometric line data, AWAGS levelled

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.
 This Isa-Georgetown Block B, QLD, 2000, Prospectivity Plus Initiative (P827), radiometric line data, AWAGS levelled were acquired in 2000 by the QLD Government, and consisted of 42035 line-kilometres of data at a line spacing between 200m and 400m, and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

AusBathyTopo (Bass Strait) 30m 2022 - A regional-scale depth model (20220003C)

The Bass Strait Digital Elevation Model (DEM) is a compilation of all available bathymetry data for the area of seabed between the coastlines of Victoria and northern Tasmania, extending approximately 460 km from west of King Island to east of Flinders Island. The Bass Strait is bounded by a continental slope incised with numerous canyons, including the prominent Bass Canyon on the eastern side. The region encompasses islands and exposed rocks, drowned paleo-shorelines and dunefields, fringed by a rugged coastline. Bathymetry mapping of the seafloor is vital for the protection of Bass Strait, allowing for safe navigation of shipping, improved environmental management and resource development. Australian Hydrographic Office-supplied ENC tile spot depths were used to develop the general bathymetry variation across the entire region. Shallow- and deep-water multibeam survey data reveal the complexity of the seafloor for the continental shelf and adjacent canyons which incise the western and eastern sides of Bass Strait. Airborne LiDAR bathymetry acquired by the Australian Hydrographic Office cover most of the northern Tasmanian nearshore and coast, with some coverage gaps supplemented by Landsat-8 satellite derived bathymetry data. The Geoscience Australia-developed Intertidal Elevation Model DEM improves the source data over the intertidal zone. Highly accurate photogrammetry coastline data developed for the Tasmania, Victoria and New South Wales coastlines, and Near Surface Feature data representing shoal features observable in aerial imagery, were used to improve the land/water interface of the numerous island and rock features. All source bathymetry data were extensively edited as 3D point clouds to remove noise, given a consistent WGS84 horizontal datum, and where possible, an approximate MSL vertical datum.This dataset is not to be used for navigational purposes.

GA0334 Vlaming sub-basin Species identification of worms from grab

The Vlaming Sub-basin Marine Survey GA-0334 was undertaken by the RV Solander in March and April 2012 as part of the Commonwealth Government's National CO2 Infrastructure Plan (NCIP). The purpose was to acquire geophysical and biophysical data to help identify sites suitable for the long term storage of CO2 within reasonable distances of major sources of CO2 emissions.
This dataset contains identifications of animals collected from 31 Van Veen grabs deployed during GA-334. Sediment was elutriated for ~ 5 minutes over a 500um sieve. Retained sediments and animals were then preserved in 70% ethanol for later laboratory sorting and identification. During sorting, all worms were separated and sent to Infaunal Pty Ltd for identification to species or operational taxonomic unit (OTU). Lynda Avery completed identifications on 17 April 2013, and specimens were lodged at the Museum of Victoria in May 2013. Blank cells in the species matrix indicate a value of '0'. Site refers to the station number, and grab refers to the cumulative number of grabs performed at that point in the survey.
Data is presented here exactly as delivered by the taxonomist, and Geoscience Australia is unable to verify the accuracy of the taxonomic identifications. 
See GA Record 2013/09 for further details on survey methods and specimen acquisition.

Depth phases from local earthquakes

Synthetic seismogram modelling and observations suggest that depth phases from local crustal earthquakes are of the type sX , where X stands for Pg, Pn , and the reflections from the crust-mantle boundary , mainly PMP and SMS. Depth phases of the type pX generally have much smaller amplitudes and are unlikely to stand out in seismograms . The differential times sX-X provide a very good control of focal depth. Examples of earthquakes that occurred in May and June 1991 in an area northwest of Kempsey (New South Wales) and in September 1991 near St George (Queensland) indicate that their foci were in the uppermost crust, at depths of between 2 and 3 km

Critical mineral potential in the Tasman Element, eastern Australia

This extended abstract presents an overview of critical minerals in Australia, with emphasis on the Tasman Element. It first defines what a critical element is, and then presents a list of critical minerals with deposit types and examples that host or potentially host the critical minerals. The geological and geochemical controls on the distribution of critical elements are then discussed, with emphasis on rare earth elements, intrusion-related rare metals, critical minerals extracted from sphalerite concentrates, and lateritic nickel, cobalt and scandium. Finally it discusses critical mineral potential in the Tasman Element and describes international, national and state government support for critical mineral exploration and development.
