Depth to magnetic basement of the Arunta-Georgina-Amadeus-Musgrave region

The depth to magnetic basement map was constructed from drill hole, seismic and magnetic depth estimation methods. The depth estimation methods included froward modelling on profile data and estimates generated from an updated spectral method. The spectral method, which provided the majority of the magnetic depth estimates, was developed by Meixner and Johnston as part of this study and is based on the Specter and Grant method that has been updated to incorporate fractal magnetisation distribution. These updates have improved depth estimation accuracy.

Great Artesian Basin groundwater flow model scenario outputs: GABtran model: Climate change

Modelled groundwater levels from 2010 to 2070 used to estimate the impact of climate change and future groundwater resource development on groundwater levels in the GAB.
The modelling considered different scenarios of climate and groundwater development: Scenario A (historical climate and current development); Scenario C (future climate and current development) and Scenario D (future climate and future development).  The future climate scenarios included the wet extreme (wet), the median (mid) and the dry extreme (dry).
The raster grids "Cdry.grd"", "Cmid.grd" and "Cwet.grd" show predicted hydraulic head for the year 2070 based on projections of future climate and the continuation of current rates of groundwater extraction 
The files "Cdry-Base.grd", "Cmid-Base.grd" and ""Cwet-Base.grd" represent predicted differences between the hydraulic heads produced by Scenario C at 2070, and the modelled spatial distributions of hydraulic head for the year 2010 (Base scenario).
The files "Cdry-A.grd", "Cmid-A.grd" and "Cwet-A.grd" represent predicted differences between hydraulic heads for 2070 produced by Scenario C and the current climate and development scenario (Scenario A).

Stratigraphic framework and structural architecture of the Upper Cretaceous in the deep-water Otway Basin – implications for frontier hydrocarbon prospectivity

Geoscience Australia has undertaken a regional seismic mapping study that extends into the frontier deep-water region of the offshore Otway Basin. This work builds on seismic mapping and petroleum systems modelling published in the 2021 Otway Basin Regional Study. Seismic interpretation spans over 18 000 line-km of new and reprocessed data collected in the 2020 Otway Basin seismic program and over 40 000 line-km of legacy 2D seismic data. Fault mapping has resulted in refinement and reinterpretation of regional structural elements, particularly in the deep-water areas. Structure surfaces and isochron maps highlight Shipwreck (Turonian–Santonian) and Sherbrook (Campanian–Maastrichtian) supersequence depocentres across the deep-water part of the basin. These observations will inform the characterisation of petroleum systems within the Upper Cretaceous succession, especially in the underexplored deep-water region.

GSWA Mt Anderson McLarty Hills North Canning 3 Doserate 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 GSWA Mt Anderson McLarty Hills North Canning 3 Doserate Grid Geodetic has a cell size of 0.00081 degrees (approximately 88m) and shows the terrestrial dose rate of the Mt Anderson - McClarty Hills, WA, 2009 (North Canning 3). The data used to produce this grid was acquired in 2009 by the WA Government, and consisted of 99192 line-kilometres of data at 400m line spacing and 60m terrain clearance.

GSNSW Exploration NSW Area G SE Darling Basin magnetic first vd 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 GSNSW Exploration NSW Area G SE Darling Basin magnetic first vd grid geodetic is a first vertical derivative of the Total Magnetic Intensity grid for the NSW DMR, Discovery 2000, 1995, S.E. Darling Basin, AREA G.
This grid has a cell size of 0.00097 degrees (approximately 100m). The grid has units of nanoTesla per km (or nT/km). The data used to produce the TMI grid was acquired in 1995 by the NSW Government, and consisted of 42604 line-kilometres of data at 400m line spacing and 80m terrain clearance. A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid.

Real-Time Community Internet Intensity Maps and ShakeMaps for Australian Earthquakes

Geoscience Australia provides 24/7 monitoring of seismic activity within Australia and the surrounding region through the National Earthquake Alerts Centre (NEAC). Recent enhancements to the earthquakes@GA web portal now allow users to view felt reports, submitted online – together with reports from other nearby respondents – using the new interactive mapping feature. Using an updated questionnaire based on the US Geological Survey’s Did You Feel It? System, Geoscience Australia now calculate Community Internet Intensities (CIIs) to support near-real-time situational awareness applications. Part of the duty seismologists’ situational awareness and decision support toolkit will be the production of real-time “ShakeMaps.” ShakeMap is a system that provides near-real-time maps of shaking intensity following significant earthquakes. The software ingests online intensity observations and spatially distributed instrumental ground-motions in near-real-time. These data are then interpolated with theoretical predictions to provide a grid of ground shaking for different intensity measure types. Combining these predictions with CIIs provides a powerful tool for rapidly evaluating the likely impact of an earthquake. This paper describes the application of the new felt reporting system and explores its utility for near-real-time ShakeMaps and the provision of situational awareness for significant Australian earthquakes.

Darwin Harbour Habitat Mapping Program: Predicted standard error for interpolated surface Carbon – Nitrogen Ratio in sediments

This resource contains a predicted carbon – nitrogen ratio standard error grid for the greater Darwin Harbour region as part of a baseline seabed mapping program of Darwin Harbour and Bynoe Harbour. This project was funded through offset funds provided by an INPEX-led Ichthys LNG Project to the Northern Territory Government’s Department of Environment and Natural Resources (NTG-DENR) with co-investment from Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS). The intent of this program is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps and information to underpin marine resource management decisions. The predicted carbon – nitrogen ratio standard error grid was derived from a compilation of multiple surveys undertaken by GA, AIMS and NTG-DENR between 2011 and 2017, including GA0333 (Siwabessy et al., 2015), GA0341 (Siwabessy et al., 2015), GA0351/SOL6187 (Siwabessy et al., 2016), GA4452/SOL6432 (Siwabessy et al., 2017), GA0356 (Radke et al., 2017), and GA0358 and GA0359 (Radke et al., 2018), adding to those from previous surveys GA4425 and GA0333 collected by GA, AIMS, NTG-DENR and Darwin Port Authority.

Euclidean Distance to the Australian Coastline

This dataset was created in ArcGIS and provides the direct distance from all grid cell points of the Australian Exclusive Economic Zone (adjacent to the mainland) to the Australian coastline. The distance measured is in decimal degrees and meters. 
The distance to the coastline is likely to reflect some degree of exposure to a wave/current regime. The proximity to land is also likely to reflect the potential influence of river discharge (sediment and fresh water), wind blown dust, and anthropogenic pollutants.
