Esperance Gravity Spherical Cap Bouguer Grid Geodetic

Gravity data measure small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 Esperance Gravity Spherical Cap Bouguer Grid Geodetic is a complete Bouguer anomaly grid for the Esperance Gravity Survey 2013 (P201361) survey. This gravity survey was acquired under the project No. 201361 for the geological survey of WA. The grid has a cell size of 0.00489 degrees (approximately 498m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 7892 gravity stations were acquired to produce this grid.

Seabed gravel, mud and sand content in the Browse region in the Australian continental EEZ 2014

This dataset provides the spatially continuous data of seabed gravel (sediment fraction &gt;2000 Âµm), mud  (sediment fraction &lt; 63 Âµm) and sand content (sediment fraction 63-2000 Âµm) expressed as a weight percentage ranging from 0 to 100%, presented in 0.0025 decimal degree (dd) resolution raster grids format and ascii text file. 
The dataset covers the Browse region in the Australian continental EEZ.
This dataset supersedes previous predictions of sediment gravel, mud and sand content for the basin with demonstrated improvements in accuracy. Accuracy of predictions varies based on density of underlying data and level of seabed complexity. Artefacts occur in this dataset as a result of insufficient samples in relevant regions. This dataset is intended for use at the basin scale. The dataset may not be appropriate for use at smaller scales in areas where sample density is insufficient to detect local variation in sediment properties. To obtain the most accurate interpretation of sediment distribution in these areas, it is recommended that additional samples be collected and predictions updated.

AUSGeoid98 v.1.0 data files:  (sj51-16)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

The 2023 National Seismic Hazard Assessment of Australia Rationale for changes in hazard

Geoscience Australia, together with contributors from the wider Australian seismology community, have produced a new National Seismic Hazard Assessment (NSHA23), recommended for inclusion in proposed updates to Standards Australia’s&nbsp;AS1170.4. NSHA23 builds on the model framework developed for NSHA18, and incorporates scientific advances and stakeholder feedback received since development of that model. Key changes include: further refinement and homogenisation of the earthquake catalogue; revisions to the fault source model through inclusion of newly identified faults and revised activity rates on some faults; assessment of ground motion models through quantitative comparison against observations; and inclusion of a specific ground motion model for shaking from plate-boundary earthquakes in northern Australia. Expert elicitation was used to capture epistemic uncertainty surrounding model choices. The elicitation focused on decision points that sensitivity analysis had shown were more important for hazard, where new models had been developed, and where model choices had been controversial in NSHA18. Key questions included which catalogue to use as the basis for calculating hazard, the weighting of different source model classes (background, regional, seismotectonic, smoothed seismicity and smoothed seismicity with faults), and the selection and weighting of ground motion models for different tectonic regions. NSHA23 hazard results for capital cities show minor changes compared with NSHA18, with the exception of Darwin. Here the ground motion with a 10% probability of exceedance in 50 years increases significantly, a result that is attributed to inclusion of a new, more realistic ground motion model for plate-boundary earthquakes in this unique tectonic setting.
This paper was presented to the 2023 Australian Earthquake Engineering Conference 23-25 November 2023 (https://aees.org.au/aees-conference-2023/)

Cambro-Ordovician conodonts from the Burke River structural belt, Queensland

Conodonts from the Upper Cambrian Chatsworth Limestone and Gola Beds and the Lower Ordovician (Tremadocian) Ninmaroo Formation were examined in order to determine the sequence of conodont species. Over 5000 specimens from 600 trough-samples representing a total of 10,000 feet of section were identified. Fifty-three species are described, of which 13 are new and 2 have been given open nomenclature. They are referred to 16 genera, of which one, Strigaconus, is new, and two are indeterminate. No Assemblage Zones could be erected for the Upper Cambrian. However, six Assemblage Zones (in ascending order - Cordylodus proavus, Oneotodus bicuspatus-Drepanodus simplex, Cordylodus oklahomensis-C. findstromi, Cordylodus prion-Scolopodus, Cordylodlls rotundatusC. anglllatus, and Chosonodina herfllrthi-AcodllS) are erected in the Tremadocian. Comparison of our zones with previously described conodont sequences from Europe, North America, and Korea shows that they can be used for intercontinental correlation. Local correlation of sections sampled over a distance of 59 miles shows a diachronous rise of the- lithological members of the Ninmaroo Formation to the south. The phylogenetic relationships of Upper Cambrian and Tremadocian conodont species are discussed. Two root-stocks are recognized in the Upper Cambrian - the coelocerodontids, and the westergaardodinids. A development from a coelocerodontid ancestor of Oneotodus nakamllrai Nogami gave rise to the majority of Tremadocian species, which are characterized by diverse cordylodids and scolopodids. The minor westergaardodinid root-stock gave rise to only two species of Chosonodina. Rates of sedimentation (calculated from the thicknesses of the conodont Assemblage Zones) show a general decrease upwards throughout the sequence, and a decrease southwards along the outcrop, from Black Mountain to Mount Datson.

Seabed imagery from IN2017_V01, Sabrina Seafloor survey, East Antarctica

Six camera tow transects were completed during survey IN2017-V01 on the RV Investigator in January to March 2017. This survey focussed on the upper slope and outer continental shelf on the Sabrina Coast seafloor in East Antarctica. Camera tows targeted seafloor depths between 480 and 1680 m. Imagery was collected using the Marine National Facilities Deep Tow Camera. This system collects oblique downward facing still images with a Canon 1DX and high definition video with a Canon C300. Four DSP&L 3150 High Output SeaLite Sphere lights were used, with MicroSeaLasers providing a 10cm scale guide on the images. Several sensors are also attached to the towed body, including a SBE 37 for CTD measurements, a Kongsberg Mesotech – 1007D altimeter, a Druck PMP 5074 pressure sensor and two Sonardyne USBLs for locational accuracy of the towed body. The USBL failed for tow A008CAM02, with locations recorded as ship’s position instead and camera position based on layback calculations. Images failed to record on A004CAM01, with only 2 images saved. Due to a timing error between the images and the other sensors, there is an offset between the CTD, altimeter and pressure data and the images. This is currently being resolved by the MNF. Tows were designed to run down slope to reduce potential for colliding with the bottom. All tows were run with a ship speed over the ground of approximately 2 kt. All still images were saved in jpeg format with video footage recorded to HD1080i50 format. The video data is unclipped and includes descent and ascent in the water column. Following collection still images were colour corrected in Adobe Photoshop to remove the blue bias. 

Images are available on the NCI with the following file structure:
MARINE IMAGERY COLLECTION
└─ PLATFORM_NAME
   └─ CAMPAIGN_NAME
      └─ DEPLOYMENT_NAME
         ├─ images/

Where
- PLATFORM_NAME is the name of the platform (e.g. Towed still imagery, Towed video imagery)
- CAMPAIGN_NAME is the name of a campaign (e.g. IN2017_V01)
- DEPLOYMENT_NAME is the name of the deployment or dive (e.g. IN2017_V01_A04_CAM01 is the voyage name, following by station number, followed by camera tow number)
- images/ is a directory containing video and still image files
- metadata.csv is a file containing position info and references to image files (e.g. timestamp, image_filename, depth from sensor on camera frame, altitude, CTD temperature, conductivity, pressure, dissolved oxygen, salinity, latitude, longitude and depth from USBL unless otherwise specified, comments)

We thank the Marine National Facility, the IN2017-V01 scientific party-led by the Chief Scientists L.K. Armand and P. O’Brien, MNF support staff and ASP crew members led by Capt. M. Watson for their help and support on board the RV Investigator. This dataset is published with the permission of the CEO, Geoscience Australia and according to MNF data policy.

GSWA Broome North Canning 1 Magnetic Grid Geodetic

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data 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 GSWA Broome North Canning 1 Magnetic Grid Geodetic has a cell size of 0.00083 degrees (approximately 90m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2009 by the WA Government, and consisted of 76474 line-kilometres of data at 400m line spacing and 60m terrain clearance.

Total sediment metabolism, bulk carbonate, mineral specific surface area, major and trace elements and carbon and nitrogen concentrations and isotopes of seabed sediments - Caswell Sub-basin, Browse Basin Marine Survey (GA0345/GA0346/TAN1411)

Geoscience Australia (GA) conducted a marine survey (GA0345/GA0346/TAN1411) of the north-eastern Browse Basin (Caswell Sub-basin) between 9 October and 9 November 2014 to acquire seabed and shallow geological information to support an assessment of the CO2 storage potential of the basin. The survey, undertaken as part of the Department of Industry and Science's National CO2 Infrastructure Plan (NCIP), aimed to identify and characterise indicators of natural hydrocarbon or fluid seepage that may indicate compromised seal integrity in the region. 
The survey was conducted in three legs aboard the New Zealand research vessel RV Tangaroa, and included scientists and technical staff from GA, the NZ National Institute of Water and Atmospheric Research Ltd. (NIWA) and Fugro Survey Pty Ltd. Shipboard data (survey ID GA0345) collected included multibeam sonar bathymetry and backscatter over 12 areas (A1, A2, A3, A4, A6b, A7, A8, B1, C1, C2b, F1, M1) totalling 455 km2 in water depths ranging from 90 - 430 m, and 611 km of sub-bottom profile lines. Seabed samples were collected from 48 stations and included 99 Smith-McIntyre grabs and 41 piston cores. An Autonomous Underwater Vehicle (AUV) (survey ID GA0346) collected higher-resolution multibeam sonar bathymetry and backscatter data, totalling 7.7 km2, along with 71 line km of side scan sonar, underwater camera and sub-bottom profile data. Twenty two Remotely Operated Vehicle (ROV) missions collected 31 hours of underwater video, 657 still images, eight grabs and one core.
This catalogue entry refers to total sediment metabolism, bulk carbonate and mineral specific surface area measurements, and major and minor trace elements and carbon and nitrogen concentrations and isotopes in the upper 2 cm of seabed sediments.

Uranium mineral systems: ore-forming processes and relationships among deposit types

Shared geological and geochemical processes are involved in the formation of particular groups of uranium deposits.  Three families of uranium mineral systems are recognised: magmatic-, metamorphic- and basin-related.  End-member fluids in each family are magmatic-hydrothermal, 'metamorphic' (including fluids reacted with metamorphic rocks at elevated temperatures), and surficial fluids such as meteoric water, lake water and seawater. Most well known uranium deposit types can be accommodated within this tripartite framework, which explicitly allows for hybrid deposit types.
