Beetaloo Sub-basin Seismic Monitoring Project

Geoscience Australia is Australia’s pre-eminent public sector geoscience organisation and is the Australian Government's trusted advisor on the geology and geography of Australia. Geoscience Australia is partnering with the Department of the Environment and Energy’s Geological and Bioregional Assessment (GBA) Program to provide information that will assess the environmental impacts of shale and tight gas development to inform regulatory frameworks and appropriate management approaches. Through this program, Geoscience Australia are conducting passive seismic monitoring deployments in the Beetaloo Sub-basin region of Northern Territory. This monitoring project aims to gather new information about natural seismic (i.e., earthquake) activity and to monitor any change to the environment due to planned hydraulic fracturing activities in the region. This information will be used by Geoscience Australia, the public and other organisations to build knowledge of potential human-induced seismic activity that may affect communities or the environment.

Hydrocarbon Migration and Seepage in the Timor Sea and Browse Basin North West Shelf Australia:  An Integrated SAR, Geological and Geochemical Study

AGSO and in collaboration with Nigel Press and Associates, AUSLIG and Radarsat International (RSI) have undertaken an interpretative study of hydrocarbon migration and seepage in the offshore Bonaparte and Browse Basins, North-Western Australia.  The study used Radarsat images, detailed water column Geochemical Sniffer and Airborne Laser Fluorosensor data, acquired over a number of many years.  The intrepertations derived from these seepage technologies were compared and contrasted, and then intergrated with a wide variety of petroleum geological information, including regional seismic data, isopach maps, key reservoirs, source and sealing units and fault maps.  All the data and many more have been placed into a 'regional' ArcView GIS associated with the final reports, Acrobat and Powerpoint files.

CERF Underwater Video and Stills from Carnarvon Shelf

Geoscience Australia carried out a marine survey on Carnarvon shelf (WA) in 2008 (SOL4769) to map seabed bathymetry and characterise benthic environments through co-located sampling of surface sediments and infauna, observation of benthic habitats using underwater towed video and stills photography, and measurement of ocean tides and wave-generated 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.
TheGA0308_Carnarvon_SOL4976 folder contains video footage and still images. The MS databse, the Excel files are video characterisation datasets: Carnarvon_video data (export).mdb;  all_substrata_tx.xls (transect level);  all_substrata_patch.xls (patch level);  all_benthos_tx.xls (transect level);  all_benthos_patch.xls (patch level);  Carnarvon_QAQC_VIDEOlog.doc  (QAQC document);  Attribute_metadata.xls (attribute definition). Underwater towed-video footage abd still images represent the raw data. Video characterisation datasets include percent cover of substrata and benthic taxa characterised at two spatial scales: transect scale (mean values per transect) and patch scale (mean values for each patch type within a transect).

Broome earthquake - Post event analysis

On 14 July 2019 a magnitude 6.6 (Mw) earthquake occurred in the Indian Ocean, 210 km WSW of Broome. This event, equal to the largest recorded in Australia, has provided an important learning opportunity. When the earthquake struck, Geoscience Australia issued an earthquake notification. The event was deemed ‘potentially tsunamigenic’, however, after further analysis, the Joint Australian Tsunami Warning Centre issued a national No Threat tsunami bulletin. No deaths or injuries were recorded and reports indicated only minor damage to buildings.
Given the low frequency and potentially high impact of earthquakes on Broome, this event was a rare opportunity for the emergency management sector to improve its understanding of this hazard. Using Geoscience Australia’s crowdsourced “Felt Reports”, DFES internal incident management system records, media reports, social media and eyewitness accounts, DFES was able to carry out a detailed post incident analysis. 
Key opportunities include: Stronger “Drop, Cover and Hold” messaging, and an improved understanding and communication of self-evacuation triggers
This poster presents WA Department of Fire and Emergency Services’ (DFES) insights and lessons learned from analysis of GA’s macroseismic information products (felt reports) as part of DFES’ post-event review of the Broome earthquake 14 July 2019.

Barlee Jackson total count grid geodetic

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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This Barlee Jackson total count grid geodetic has a cell size of 0.00083 degrees (approximately 86m) and shows the terrestrial dose rate of the Barlee, Jackson, WA, 1997. The data used to produce this grid was acquired in 1997 by the WA Government, and consisted of 104998 line-kilometres of data at 400m line spacing and 50m terrain clearance.

Antipodean fugitive terranes in southern Laurentia

Paleoproterozoic arc and backarc assemblages accreted to the south Laurentian margin between 1800 Ma and 1600 Ma, and previously thought to be indigenous to North America, more likely represent fragments of a dismembered marginal sea developed outboard of the formerly opposing Australian-Antarctic plate. Fugitive elements of this arc-backarc system in North America share a common geological record with their left-behind Australia-Antarctic counterparts, including discrete peaks in tectonic and/or magmatic activity at 1780 Ma, 1760 Ma, 1740 Ma, 1710-1705 Ma, 1690-1670 Ma, 1650 Ma and 1620 Ma. Subduction rollback, ocean basin closure and the arrival of Laurentia at the Australian-Antarctic convergent margin first led to arc-continent collision at 1650-1640 Ma and then continent-continent collision by 1620 Ma as the last vestiges of the backarc basin collapsed. Collision induced obduction and transfer of the arc and more outboard parts of the Australian-Antarctic backarc basin onto the Laurentian margin where they remained following later breakup of the Neoproterozoic Rodinia supercontinent. North American felsic rocks generally yield Nd depleted mantle model ages consistent with arc and backarc assemblages built on early Paleoproterozoic Australian crust as opposed to older Archean basement making up the now underlying Wyoming and Superior cratons.

Probabilistic Inversion of Audio-frequency Magnetotelluric Data and Application to Cover Thickness Estimation for Mineral Exploration in Australia

We have developed a Bayesian inference algorithm and released open-source code for the 1D inversion of audio-frequency magnetotelluric data. The algorithm uses trans-dimensional Markov chain Monte Carlo to solve for a probabilistic resistivity-depth model. The inversion employs multiple Markov chains in parallel to generate an ensemble of millions of resistivity models that adequately fit the data given the assigned noise levels. The trans-dimensional aspect of the inversion means that the number of layers in the resistivity model is solved for rather than being predetermined. The inversion scheme favours a parsimonious solution, and the acceptance criterion ratio is theoretically derived such that the Markov chain will eventually converge to an ensemble that is a good approximation of the posterior probability density (PPD). Once the ensemble of models is generated, its statistics are analysed to assess the PPD and to quantify model uncertainties. This approach gives a thorough exploration of model space and a more robust estimation of uncertainty than deterministic methods allow.
We demonstrate the application of the method to cover thickness estimation for a number of regional drilling programs. Comparison with borehole results demonstrates that the method is capable of identifying major stratigraphic structures with resistivity contrasts. Our results have assisted with drill site targeting, and have helped to reduce the uncertainty and risk associated with intersecting targeted stratigraphic units in covered terrains. Interpretation of the audio-frequency magnetotelluric data has also improved our understanding of the distribution and geometries of sedimentary basins undercover. From an exploration perspective, mapping sedimentary basins and covered near-surface geological features supports the effective search for mineral deposits in greenfield areas.
