Frome Embayment TEMPEST AEM Survey: Inversion Report and Data Package

Airborne Electromagnetic data are being acquired by Geoscience Australia in areas considered to have potential for uranium or thorium mineralisation under the Australian Government's Onshore Energy Security Program (OESP). The surveys have been managed and interpreted by Geoscience Australia's Airborne Electromagnetic Acquisition and Interpretation project. In contrast to industry style deposit scale investigations, these surveys are designed to reveal new geological information at regional scale. The Frome Embayment AEM survey was acquired using the TEMPESTTM AEM system by Fugro Airborne Surveys under contract to GA. The survey covers a total of 32 300 line km and an area of 95 450 km2, the largest AEM survey by area ever flown in Australia.
Phase-1 data, that is, contractor quality-controlled and quality-assessed data for the Frome survey, were released during March 2011. Phase-2 data, that is Geoscience Australia layered earth inversion (GA-LEI) data and derived products are included in this data release. The data and products described in this report are available from the GA AEM website, and are contained on the accompanying DVD.

Sea Level Monitoring Project : CGPS Coordinate Time Series Analysis Report

The Sea Level Monitoring Project was initially developed in the early 1990's (known at that time as the South Pacific Sea Level and Climate Monitoring Project) as a response to concerns expressed by South Pacific Forum Leaders about the potential impacts of global warming on sea levels and climate in the South Pacific. This Australian aid project was established with the goal of providing an accurate, long term record of sea levels in the South Pacific both for Forum countries and for the international scientific community that need such information to better understand how the Pacific oceanographic and meteorological environment is changing. During the 1990's a network of high resolution sea level and climate monitoring stations was established in the South West Pacific and observations from those stations were made available to stakeholders. In 2001, a Continuous Global Positioning System (CGPS) monitoring component was added and CGPS instruments were established near and linked to the sea level tide gauges stations in all partner countries so as to enable the measurement of vertical land movements. Vertical land motion at sea level stations can be equal or larger than the local absolute sea level signal, thus masking sea level change related information recorded at those stations. Therefore, the CGPS network is a crucial component for reliably determining absolute sea level change. This document reports the analysis results of CGPS coordinate time series from 2001 to 2013.

St Arnaud uranium 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.
This radiometric uranium grid has a cell size of 0.00042 degrees (approximately 42m) and shows uranium element concentration of the St Arnaud Infill merge, 1990 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1990 by the VIC Government, and consisted of 18970 line-kilometres of data at a line spacing between 200m and 400m, and 100m terrain clearance.

A multidisciplinary geoscientific approach for understanding Australia's hidden groundwater potential - Geoscience Australia's Exploring for the Future Program

Groundwater is critical to Australia’s future economic development and is the only reliable water source for many regional and rural communities. It also sustains environmental and cultural assets including springs and groundwater-dependent ecosystems. The demand for groundwater in Australia is expected to increase with population growth, economic development and climate change. Geoscience Australia, in partnership with Commonwealth, State and Territory governments is delivering national and regional groundwater investigations through the Exploring for the Future (EFTF) Program to support water management decisions.
Geoscience Australia’s groundwater studies apply innovative geoscience tools and robust geoscientific workflows to increase knowledge and understanding of groundwater systems and assessment of groundwater resource potential for economies, communities and the environment. Through integrating geological and hydrogeological data, airborne electromagnetic and ground-based geophysical, hydrogeochemical and remote sensing data, we have developed new geological and hydrogeological conceptual models and identified potential managed aquifer recharge sites in a number of areas across Northern Australia. 
The EFTF program is focussed on improving our understanding of Australia's groundwater through a National Groundwater Systems project as well as two regional-scale groundwater investigations in Southern Australia. We are commencing an inventory of Australia’s groundwater systems in onshore basins that includes a compilation and broad interpretation of hydrogeological information. This is the basis for the collation and curation of nationally seamless groundwater information to support informed decision making and water resource coordination across jurisdictions. 
All data and value-added products are freely available for public use via the Exploring for the Future Data Discovery portal (https://portal.ga.gov.au/).
This Abstract was submitted to the 2022 Australasian Groundwater Conference 21-23 November (https://agc2022.com.au/)

AUSGeoid98 v.1.0 data files: (se57-11)

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 signature of terrestrial impacts

The high level of endogenic geological activity makes the terrestrial record of impact difficult to read. Terrestrial processes, such as erosion, rapidly modify craterforms and ultimately remove the evidence of impact. In their largely uneroded states, terrestrial impact structures have the basic so-called simple and complex forms observed on other planetary bodies, but few of them have morphometric parameters, such as apparent and true depth and stratigraphic uplift, that can be defined.  Erosion severely affects such parameters, and can even result in a positive topographic form due to differential erosion. The principal criterion for the recognition of terrestrial impact structures is, therefore, not their form, but the occurrence of shock-metamorphic effects. These are well-documented and are described briefly. In parautochthonous target lithologies, they are limited to the central portion of the original crater floor, and attenuate radially and with depth. Shock effects also occur in allochthonous lithologies, such as breccias and impact-melt rocks.  In addition to a characteristic geological signature, terrestrial impact structures have characteristic geophysical signatures. The most common is a Bouguer gravity low, which extends out to the rim. The low is due to impact-induced brecciation and fracturing . It increases in value with increasing size, reaching a limiting value of ~300 Âµm s-2 (~300 g.u.).  In large impact structures, it can be accompanied by a central relative high. The magnetic signature can be more varied but generally corresponds to a subdued low. Local intense magnetic anomalies can occur in the centres of large structures, D &gt;40 km; these magnetic highs have various sources, but many are due to post-impact hydrothermal alteration.  Impact can also lead to a reduction in seismic velocities and resistivity of the target rocks.  The geophysical, geological, and morphological characteristics at terrestrial impact structures are summarised in tabular form as an aid to the recognition of additional structures.
