Isotopic Atlas of Australia: Geochronology compilation for South Australia. Version 1.0

This Record presents the first version of a South Australia (SA) geochronology compilation developed as part of Geoscience Australia’s Isotopic Atlas of Australia, which commenced under the Exploring for the Future (EFTF) program and continues to support the objectives of the Resourcing Australia's Prosperity initiative (RAPi). The compilation brings together 1,101 interpreted radiometric ages for geological units across South Australia, derived from Geoscience Australia’s Sensitive High Resolution Ion Microprobe (SHRIMP) datasets, Geological Survey of South Australia technical reports, peer-reviewed literature and academic theses. While non-exhaustive, the compilation provides a consistent and standardised framework for examining the timing of geological processes across the State. Completion of the SA compilation represents a significant milestone for the Isotopic Atlas, achieving continent-wide coverage of interpreted geochronological data.



Ages in the SA compilation are derived from both borehole samples (539) and outcrop samples (562), supporting regional-scale geological synthesis. The dataset spans a broad temporal range from the Paleoarchean to the Cenozoic (~3250 to 2.2 Ma), reflecting the long and episodic geological evolution of South Australia. It is dominated by U–Pb geochronology, with fewer contributions from Rb–Sr, Sm–Nd, K–Ar, Ar–Ar and Re–Os systems. Recorded geological events include igneous crystallisation, metamorphism, deposition, hydrothermal activity, cooling, deformation, mineralisation and isotopic resetting. Temporal analysis highlights a dominant Proterozoic concentration of igneous crystallisation ages (~1800–1550 Ma), consistent with major tectono-magmatic events in South Australia, particularly within the Gawler Craton, and a smaller early Paleozoic peak (~550–400 Ma) associated with the Delamerian Orogeny. The compilation is spatially biased toward the Gawler Craton, and interpretations are therefore weighted toward its geological history; improved coverage of other provinces and isotopic systems is anticipated in future updates.



The SA geochronology compilation is accessible via the Geoscience Australia Data Portal, GA Web Services and a static snapshot associated with this Record, supporting interactive analysis, flexible data download and GIS integration. This first-pass compilation establishes a robust foundation for temporal geological analysis and provides a framework for the ongoing expansion and refinement of South Australia’s geochronological record.

Quantitative mapping of the East Australian Current encroachment using time series Himawari-8 sea surface temperature data

The East Australian Current (EAC) is a complex and highly dynamic western boundary current (WBC) component of the South Pacific Gyre. The interaction between the EAC and the continental shelf significantly influences the coastal ocean dynamics and the marine ecosystem off the southeast coast of Australia. In this study, we attempted to map the spatial structure of the sea surface temperature (SST) signature of the EAC system using Himawari-8 SST data, and to investigate the spatial and temporal evolution of the EAC encroachment for the period July 2015 to Sept 2017. The very high spatiotemporal resolution of Himawari-8 SST images has enabled the mapping of the highly dynamic EAC using a Topographic Position Index (TPI) method. The results demonstrated that the TPI mapping was able to capture the complex spatial structure of the EAC system, based on which the spatial variability and temporal evolution of EAC’s meanders, offshoots, separation, eddies, and extensions along its path have been clearly documented. Using an eddy-resolving, data assimilating numerical ocean model, we were able to relate the EAC's SST signature with its surface current speed signature, with an overall area ratio of overlap ~60% between the two signatures. Temporal wavelet analyses indicated that the variability of the EAC encroachment is dominated by an eddy-shedding timescale, being 65~80 days upstream and 90~100 days downstream of the EAC separation point. In the upstream, the EAC’s proximity to the coast also exhibited seasonal cycle in the 2 year (26 months) study period, with the encroachment being stronger during austral summer and weaker during austral winter. Off the eastern coast of Tasmania, powerful summer pulses of the EAC encroachment were observed, which is an expression of the seasonality of the EAC boundary flow in this region. Upstream, we believe that the “encroach and accelerate” mode of the EAC would drive coastal upwelling which can occur all year round with local maximum typically in summer. Downstream, the “encroach and decay” mode of the western arm of the EAC or its eddies is less likely to induce and sustain bottom water uplift. The seasonal current sheer previously observed upstream on the continental shelf is believed to be a combined effect of the stronger EAC encroachment and the enhanced temperature difference between shelf and EAC waters (i.e. thermal wind effect) in summer compared to winter.

Ambient Noise Tomography of The Australian Continent Using 40 Years of Passive Seismic Records in Australia

The Australian continental crust has a rich and complex tectonic history, reflected in seismic tomography by sharp velocity contrasts. In this study, we utilise data from all available temporary seismic deployments in Australia through AusPass (https://auspass.edu.au/), the Australian Permanent Seismic Network (ANSN), and the  AusArray network (https://www.eftf.ga.gov.au/ausarray), which covers the continent in a 2° × 2° array. AusArray, initially funded through the Exploring for the Future program continues with an expanded deployment as part of the Resourcing Australia's Prosperity initiative.   We compute hourly cross-correlations and stack them to generate noise correlation functions (NCFs) for each station pair. Dispersion curves are extracted from NCF spectra using an automated workflow, enabling us to perform ambient noise tomography (ANT) across the Australian continent.

Our ANT model, constructed from surface wave velocity maps from 60s to 2s periods, resolves well-known major sedimentary basins as well as several recently discovered smaller basins. We validate our model against deep-crustal active seismic profiles in Australia and observe remarkable agreement between the two datasets. Additionally, we compare our results with borehole data, interpreted basin analysis from gravity, magnetic, and active seismic surveys, revealing the lateral extent and depth of major basins such as the Canning, Officer, and Great Artesian basins. In the Great Artesian Basin, we detect extremely low velocities in regions with significant water saturation. These findings highlight ANT as a robust tool for imaging first-order, large-scale crustal structures, offering valuable insights into Australia’s geological framework.

Redmap (New South Wales) - Sightings of Shark and Ray Species

Redmap is a primarily a website that invites the community to spot, log and map marine species that are uncommon in their region, or along particular parts of their coast. The information collected is mapped and displayed on the site, demonstrating, in time, how species distributions may be changing.

Sightings are divided into two categories – those with a photo that can be ‘verified’ by a marine biologist, and sightings without photos that we call community sightings (anecdotal). All the information collected, with and without photos, is mapped and will be used in the following years to map out a ‘story’ of changes occurring in our marine environment.

The main data collected includes the species sighted (normally selected from a list comprising preselected species of interest), the location, date/time and activity being undertaken.  Other optional information gathered include biological data such as sex, size and weight and environmental data such as water depth and temperature and habitat.

This record is associated with live data (and will subsequently change over time) and spatial elements have reduced accuracy.  It is also subject to a three year embargo (ie. does not contain data less than three years old).  If you wish to discuss obtaining a citable, static dataset, that is current and/or contains accurate spatial elements, please email enquiries@redmap.org.au.

Quantifying fish behaviour and commercial catch rates in relation to a marine seismic survey

The impact of seismic surveys on the catchability of marine fish is a contentious issue, with claims that seismic surveys may negatively affect catch rates. However little empirical evidence exists to quantify the impacts or determine potential causes. In this study, we used a 2-D seismic survey in the Gippsland Basin, Bass Strait, Australia in April 2015 as an opportunity to quantify fish behaviour (field-based) and commercial fisheries catch (desktop study) across the region before and after airgun operations. Three species found in abundance (gummy shark, swell shark, tiger flathead) were acoustically tagged and released within one of two acoustic arrays (experimental and control zone) and monitored before, during and after the seismic survey. In the field study, only 35% of the gummy sharks and 30% of the swell sharks were subsequently detected two days after release, although various individuals returned sporadically over the period of monitoring including during the seismic survey operations. Behaviour consistent with a possible response to the seismic survey operations was restricted to flathead which increased their swimming speed during the seismic survey period and changed their diel movement patterns after the survey. We also investigated the potential impacts of the seismic survey on catch rates using Commonwealth fisheries logbook data from Jan 2012 – Oct 2015. Fifteen species and two gear types (Danish seine, gillnet) were modelled to examine differences in catch rates before and after the seismic survey. The catch rates in the six months following the seismic survey were different than predicted in nine out of the 15 species examined, with six species (tiger flathead, goatfish, elephantfish, boarfish, broadnose shark and school shark) showing increases in catch following to the seismic survey, and three species (gummy shark, red gurnard, sawshark) showing reductions. Overall, we found little evidence consistent with behavioural or catch rate changes induced by the seismic survey in the targeted species, although behavioural data were limited because many sharks left the acoustic receiver array prior to the commencement of the seismic survey.
