Preview of Geoscience Australia's Science Strategy 2028

Geoscience Australia's value to the nation, outlined in our overarching Strategy 2028, is through our science.  However, the way that we apply our science to support a strong economy, resilient society and sustainable environment cannot be taken for granted. 
Our new Science Strategy 2028, to be launched by Geoscience Australia's Chief Scientist, Dr Steve Hill, during this event, will support Strategy 2028 in our mission to be the nation's trusted advisor on the geology and geography of Australia. It will provide strategic direction for developing and delivering the science that underpins our core business. 
Dr Hill will outline how our guiding Science Principles apply to our way of working -- not just the way in which we work as an organisation, but also in the way that we work with our partners in using science to create benefits for all Australians.

A National Space Policy: Views from the Earth Observation Community

Australia has been receiving Earth Observations from Space (EOS) for over 50 years. Meteorological imagery dates from 1960 and Earth observation imagery from 1979. Australia has developed world-class scientific, environmental and emergency management EOS applications. 
However, in the top fifty economies of the world, Australia is one of only three nations which does not have a space program. The satellites on which Australia depends are supplied by other countries which is a potential problem due to Australia having limited control over data continuity and data access.
The National Remote Sensing Technical Reference Group (NRSTRG) was established by Geoscience Australia as an advisory panel in 2004. It represents a cross-section of the remote sensing community and is made up of representatives from government, universities and private companies. Through the NRSTRG these parties provide Geoscience Australia with advice on technical and policy matters related to remote sensing. 
In February 2009 the NRSTRG met for a day specifically to discuss Australia's reliance on EOS, with a view to informing the development of space policy. This report is the outcome of that meeting. Australia has some 92 programs dependent on EOS data. These programs are concerned with environmental issues, natural resource management, water, agriculture, meteorology, forestry, emergency management, border security, mapping and planning. Approximately half these programs have a high dependency on EOS data. While these programs are quite diverse there is considerable overlap in the technology and data.
Of Australia's EOS dependent programs 71 (77%) are valued between $100,000 and $10 million and 82 (89%) of all these programs have a medium or high dependency on EOS data demonstrating Australia's dependency on space based imaging.
Earth observation dependencies within currently active Federal and state government programs are calculated to be worth just over $949 million, calculated by weighting the level of dependency on EOS for each program. This includes two programs greater than $100 million in scale and one program greater than a billion dollars in scale. 
This document is intended as a summary of Australia's current space and Earth observation dependencies, compiled by the NRSTRG, to be presented to the Federal Government's Space Policy Unit, a section of the Department of Innovation, Industry, Science and Research, as an aid to space policy formation.

GSV East Gippsland Vic 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 GSV East Gippsland Vic magnetic grid geodetic has a cell size of 0.0005 degrees (approximately 49m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 1998 by the VIC Government, and consisted of 16736 line-kilometres of data at a line spacing between 200m and 400m, and 75m terrain clearance.

Australian extreme windspeed baseline climate investigation project

This study has examined the observed record of peak gust wind speed (daily maximum 3-second averaged gust wind speed) in order to establish the existence of bias between the early part of the record (measurements obtained using pressure-tube Dines anemometers) and the later part of the record (measurements obtained using cup anemometers). 
All observational data as well as metadata was obtained from the Bureau of Meteorology. The 38 recording stations considered were in the most part staffed by Bureau of Meteorology officers. To isolate the issue of anemometer replacement, only observing stations located at airports (i.e. those with consistent exposure) and with more than 30 years of record were considered. The visual inspection of the observed daily peak gust wind speed time-series for most of the Bureau of Meteorology observing sites considered in this study is sufficient to indicate that in general the early part of the observing record contains a higher frequency of extreme events, and also the largest amplitude extreme events.
Statistical analysis of the daily maximum gust wind speed observations was conducted by employing extreme value distributions (EVD) to examine the difference between two datasets:
(1) time-series of Dines &amp; cup anemometer observations (no overlap for each station)
(2) coincident Dines &amp; cup anemometer observations

The Delamerian Orogen: exposing an undercover arc

Short abstract: The Delamerian Orogen is spatially and temporally extensive, covering five states in central and eastern Australia. The orogen records the transition from Proterozoic Australia to the Phanerozoic Tasmanides, starting with rifting of the Rodinian supercontinent and transition to a passive margin from ca. 830 to 530 Ma, then developing as a convergent eastern Gondwanan margin from ca. 530 Ma that was terminated by the mid-to-late Cambrian Delamerian Orogeny. The orogen was later impacted by younger geodynamic events, particularly in the Ordovician-Silurian-Devonian. Due to the paucity of exposure, in particular in its central segment, and the complex cover sequences, significant parts of the Delamerian Orogen remain poorly documented. The orogen is also underexplored for resources despite demonstrated potential for magmatic-hydrothermal and other mineral systems. As part of the Exploring for the Future program, the Darling-Curnamona-Delamerian project is working to improve geodynamic framework and mineral systems knowledge through a range of activities including; analysis of legacy drill core, new stratigraphic drilling and major geophysical data acquisition campaigns (airborne electromagnetic, deep crustal seismic reflection, magnetotelluric). Significant first results reveal the existence of a corridor of Siluro-Devonian igneous rocks flanked by Cambrian igneous rocks within the Loch Lilly-Kars Belt, possibly related to an episode of rifting or extension, with potential for rift-related and magmatic-hydrothermal mineral systems of that age.

Geochemical Mass Transfer Patterns as Indicators of the Architecture of a Complete Volcanic-Hosted Massive Sulfide Hydrothermal Alteration System in the Panorama District, Pilbara, Western Australia

Outstanding exposure across the Panorama district, in the Archean Pilbara block of Western Australia, reveals a cross section through a complete volcanic-hosted massive sulfide (VHMS) hydrothermal alteration system in an area of low metamorphic grade and very low strain. Geochemical maps, in combination with alteration maps, document mass transfer across this alteration system. Feldspar-bearing rocks at the top of the volcanic pile are enriched in K and Si, but depleted in Na, in contrast to those at the bottom of the volcanic pile that are enriched in Na and depleted in K. Sericite-quartz altered rocks are typically enriched in Si and depleted in Ca, Na, and Fe, whereas chlorite-quartz altered rocks, which dominate transgressive feldspar-destructive alteration zones, are marked by K-Ca-Na depletion and Mg-Fe enrichment. 
Copper and Zn are strongly depleted in rocks at the base of the volcanic pile and, to a lesser extent, in transgressive feldspar-destructive alteration zones. The amount of metal leached from the volcanic pile is far greater than that contained in known deposits, and thus a magmatic metal source is not necessary to explain the formation of the Panorama VHMS deposits. 
Mass-transfer patterns at Panorama have similarities to existing models for regional VHMS hydrothermal alteration systems, including the distribution of alkali elements in feldspar-bearing semiconformable alteration zones and the presence of a base metal-depleted zone at the base of the volcanic pile. However, there are significant differences, both in the architecture of the hydrothermal alteration system and in mass-transfer patterns. These include Si enrichment rather than depletion at the top of the volcanic pile, widespread Mg enrichment outside of the upper semiconformable alteration zones, the absence of a silica cap rock above the base metal depleted zone, more hydrous alteration assemblages in the zones of base metal depletion, and extensive zones of transgressive feldspar-destructive alteration.

Hydrogeology of the Adavale, Cooper, Galilee and north Bowen basins

The Australian Government's Trusted Environmental and Geological Information program is a collaboration between Geoscience Australia and CSIRO. Part of this program includes baseline geological and environmental assessments. 

Hydrogeological information has been collated for the Adavale, Cooper, Galilee and north Bowen basins and overlying basins, including the Eromanga and Lake Eyre basins. This information will provide a regionally-consistent baseline dataset that will be used to develop groundwater conceptualisation models.

Publicly-available data within these basin regions have been compiled from over 30&nbsp;000 boreholes, 120 stream gauges, and 1100 rainfall stations, resulting in revised hydrostratigraphic frameworks. From the published literature, 14 major hydrostratigraphic units are recognised within the basin regions. For each of these major hydrostratigraphic units, we determined the salinity, Darcian yield, specific yield/storativity, groundwater reserve volume for unallocated groundwater, groundwater levels/hydrological pressure, likelihood of inter-aquifer connectivity, rainfall, connectivity between surface water and groundwater, and water-use volume statistics, where relevant, for each basin, hydrogeological province and aquifer. We then adopted a play-based approach to develop holistic hydrostratigraphic conceptualisations of the basin regions. 

Within the Adavale Basin we have defined a new hydrogeological province including two new aquifers defined as the moderate salinity and moderately overpressured Buckabie-Etonvale Aquifer, and the hypersaline and hyper-overpressured Lissoy-Log Creek-Eastwood Aquifer. Similarities between the upper Buckabie-Etonvale Aquifer of the Adavale Basin and lowermost Joe Joe Group of the Galilee Basin suggests connectivity between the upper Adavale and lower Galilee basins. Hydraulic pressures (up to 1500 m of excess freshwater head) calculated for the Lissoy–Log Creek–Eastwood Aquifer indicate that if the aquifer was to be breached, there is potential localised risk to overlying aquifers and surface environments, including infrastructure.
