Improving how we engage with land-connected people about geoscience

Output Type: Exploring for the Future Extended Abstract

Short Abstract: Under the Exploring for the Future (EFTF) program, Geoscience Australia staff and collaborators engaged with land-connected stakeholders that managed or had an interest in land comprising 56% of the total land mass area of Australia. From 2020 to 2023, staff planning ground-based and airborne geophysical and geological data acquisition projects consulted farmers, National Park rangers and managers, Native Title holders, cultural heritage custodians and other land-connected people to obtain land access and cultural heritage clearances for surveys proposed on over 122,000 parcels of land. Engagement did not always result in field activities proceeding. To support communication with this diverse audience, animations, comic-style factsheets, and physical models, were created to help explain field techniques. While the tools created have been useful, the most effective method of communication was found to be a combination of these tools and open two-way discussions.

Cambridge Pendulum Isogals (P195099), gravity point data

Gravity data measures 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 Cambridge Pendulum Isogals (P195099) contains a total of 57 point data values acquired at a spacing of 250000 metres. The data is located in ACT, NSW, NT, QLD, SA, TAS, VIC, WA and were acquired in 1950, under project No. 195099 for Bureau of Mineral Resources (BMR).

A regional perspective of the Paleo- and Mesoproterozoic petroleum systems of northern Australia

Seismic reflection mapping, geochemical analyses and petroleum systems modelling have increased our understanding of the highly prospective Mesoproterozoic and Paleoproterozoic source rocks across northern Australia, expanding the repertoire of exploration targets currently being exploited in Proterozoic petroleum systems. Data collected during the Exploring for the Future program have enabled us to redefine and increase the extent of regional petroleum systems, which will encourage additional interest and exploration activity in frontier regions. Here, we present a review of the Paleoproterozoic McArthur and Mesoproterozoic Urapungan petroleum supersystems, and the most up-to-date interpretation of burial and thermal history modelling in the greater McArthur Basin (including the Beetaloo Sub-basin), South Nicholson Basin and Isa Superbasin. We also present potential direct hydrocarbon indicators imaged in the 2017 South Nicholson Deep Crustal Seismic Survey that increase the attractiveness of this frontier region for hydrocarbon exploration activities.

Linking patterns and processes on a tropical sediment-starved shelf: Insights from cluster analysis on physical and geochemical variables

Geoscience Australia undertook seabed mapping surveys in the eastern Bonaparte Gulf in 2009/2010 to deliver integrated information relevant to marine biodiversity conservation and offshore infrastructure development. The survey objectives were to characterise the physical, chemical and biological properties of the seabed, document potential geohazards and to identify unique or sensitive benthic habitats and collect baseline information on these habitats.  Different clustering methods were applied to a 124 sample dataset comprising 74 physical and geochemical variables which describe organic matter (OM) reactivity/quantity/source and geochemical processes relevant to biodiversity. Infauna data were used to assess different groupings because they are an important food source for epibenthic crustaceans and fish and purveyors of ecosystem services including nutrient cycling and mineralisation. Clusters based on physical/geochemical data discriminated infauna better than geomorphic features. Major variations amongst clusters included grainsize and a cross-shelf transition in from authigenic-Mn /As enrichments (inner shelf) to authigenic-P enrichment (outer shelf) which relate to energy levels and sediment oxygen status. Groups comprising raised features had the highest reactive OM concentrations (e.g. based on  low chlorin indices and C:N-ratios, and high k) and benthic algal -13C signatures. Surface area normalised OM concentrations higher than continental shelf norms were observed in association with: (i) low -15N, inferring Trichodesmium input; and (ii) pockmarks. The pockmarks are shown to impart bottom-up controls on seabed chemistry and cause inconsistencies between bulk and pigment OM pools. The geochemical data and clustering methods provide insight into ecosystem processes which influence biodiversity patterns in the region.  Low Shannon-Wiener diversity occurred in association with low porewater pH and evidence for low sediment redox status and high energy levels, while the highest beta-diversity was observed at euphotic depths. Pair-wise ANOSIM results for infauna are brought together in a summary model which highlights the influence of the clusters on beta diversity.

Toward an effective global green economy: International Critical Minerals Mapping Initiative (CMMI)

Critical minerals can be defined as mineral commodities that are essential for economic or techological development but have significant supply risk owing to geological, technological or political factors. Geoscience Australia, along with the United States Geological Survey and the Geological Survey of Canada, have entered into a joint project, the Critical Minerals Mapping Initiative, to decrease this supply risk through a better understanding of geological controls on the distribution and deportment of critical minerals in mineral systems. This project will improve this understanding through (1) documentation of the concentration of critical minerals in ores, (2) development of mineral deposit/system classification that will enable assessment of system- and deposit-scale analysis of these concentration data, and (3) development of models to predict and model mineral potential of major and critical commodities in mineral systems, including basin-hosted, iron oxide-copper-gold and porphyry epithermal systems, at the global, craton, province and district scales. These new data and understandings will reduce the supply risk for critical minerals and enhance discovery of these and related minerals world-wide.

Cobar P5009 EXT 4 Potassium ground concentration grid

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 potassium grid has a cell size of 0.00039074 degrees (approximately 40m) and shows potassium element concentration of the Cobar Magnetic and Radiometric Survey, 2021 in units of percent (or %). The data used to produce this grid was acquired in 2021 by the NSW Government, and consisted of 53617 line-kilometres of data at 200m line spacing and 60m terrain clearance.

Murray Basin Hydrogeological Project : progress report 10 for half year ending 30 September 1983

The Steering Committee met in June. An important aspect of the meeting was a discussion on the hydrogeological phase of the Project, which at Bureau of Mineral Resources (BMR) formally began at the beginning of July.  It was considered that the hydrogeological assessment should include: 
the acquisition from State Authorities of all available data, which would then be entered into a BMR database designed for the Project; 
the preparation of an initial report assessing the available data and recording deficiencies, together with accompanying maps including the following: 
     1:1 million scale water table and potential contours for the three/four hydrostratigraphic units; 
     1:1 million scale salinity variations including specific ions, for the three/four hydrostratigraphic units; 
     1:2.5 million scale maps depicting amount of water abstracted-added per unit area, recharge-discharge areas, distribution and type of salting, streamflow-groundwater interactions, and distribution of aquifer parameters for a 7-layer hydrogeological model (aquifers and aquicludes).
Compilation of the 1:1 million scale geological map of the basin continued at BMR.

AUSGeoid98 v.1.0 data files:  (sd54-10)

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.

Evaluating Geoscience Australia's Groundwater Activities - Impact and Return on Investment Study

The Exploring for the Future program is a world leading program, delivering public geoscientific data and information required to empower decision-makers and attract future investment in resource exploration and development. Geoscience Australia engaged Alluvium Consulting Australia to quantify the impact and value of groundwater activities and outputs to the quadruple bottom line through an evaluation of 2 case studies, namely: 

• National Hydrogeological Mapping 
• The Southern Stuart Corridor project. 

This involved understanding the impact pathways for these case studies and the collection of data to be used in a cost benefit analysis. The work sought to provide feedback to Geoscience Australia, stakeholder groups and the broader community on the value of Geoscience Australia’s groundwater activities. 

The case study evaluations were facilitated by a series of specific questions, which were developed to guide data collection and the building of a knowledge base around the impact and value of the work in each case study and associated outputs. The questions broadly fell under the following categories: 

1. Uptake and Usage 
2. Impact 
3. Benefit 

These evaluations were framed around the program impact pathway developed for each case study. This is a description of how inputs are used to deliver activities, which in turn result in outcomes and impacts (changes) for stakeholders, including the environment. 

The primary means of data collection to help answer the key evaluation questions was through online workshops and interviews with key stakeholders for each case study. These were undertaken between March 10 and March 24, 2023. In these workshops and interviews, representatives from industry, community and government agencies were asked if they could identify instances where case study program outputs were used for particular purposes, such as prioritising research or investment, advising Members of Parliament, or education and training. These examples were then explored further to understand what outcomes and benefits were derived from the use of the case study outputs, and how critical were the case study outputs to achieving those outcomes and benefits

Outer Darwin Harbour Marine Survey 2015: Total sediment metabolism, mineral specific surface area, carbonate and element concentrations and C and N isotopes in seabed sediments.

This resource contains surface sediment data for Outer Darwin Harbour collected by Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Northern Territory Government (Department of Land Resource Management) during the period from 28 May and 23 June 2015 on the RV Solander (survey SOL6187/GA0351). This project was made possible through offset funds provided by INPEX-led Ichthys LNG Project to Northern Territory Government Department of Land Resource Management, and co-investment from Geoscience Australia and Australian Institute of Marine Science. The intent of this four year (2014-2018) 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 that underpin marine resource management decisions. The specific objectives of the survey were to:

Obtain high resolution geophysical (bathymetry) data for outer Darwin Harbour, including Shoal Bay;
Characterise substrates (acoustic backscatter properties, grainsize, sediment chemistry) for outer Darwin Harbour, including Shoal Bay; and 
Collect tidal data for the survey area.

Data acquired during the survey included: multibeam sonar bathymetry and acoustic backscatter; physical samples of seabed sediments, underwater photography and video of grab sample locations and oceanographic information including tidal data and sound velocity profiles. These datasets comprise total sediment metabolism, mineral specific surface area and carbonate and element concetrations, and C and N isotopes of seabed sediments.
