Understanding potential resource prospectivity 1D burial and thermal history modelling of the Adavale Basin

Lateral variation in maturity of potential Devonian source rocks in the Adavale Basin have been investigated using nine 1D burial thermal and petroleum generation history models, constructed using existing open file data. These models provide an estimate of the hydrocarbon generation potential of the basin. Total organic carbon (TOC) content and pyrolysis data indicate that the Log Creek Formation, Bury Limestone and shale units of the Buckabie Formation have the most potential as source rocks. The Log Creek Formation and the Bury Limestone are the most likely targets for unconventional gas exploration.

&nbsp;

The models were constructed used geological information from well completion reports to assign formation tops and stratigraphic ages to then forward-model the evolution of geophysical parameters. The rock parameters, including facies, temperature, organic geochemistry/petrology, were used to investigate source rock quality, maturity and kerogen type. Suitable boundary conditions were assigned for paleo-heat flow, paleo-surface temperature and paleo-water depth. The resulting models were calibrated using bottom hole temperature and measured vitrinite reflectance data.

&nbsp;

The results correspond relatively well with published heat flow predictions, however a few wells show possible localised heat effects that differ from the overall basin average. The models indicate full maturation of the Devonian source rocks with generation occurring during the Carboniferous and again during the Late Cretaceous. Any potential accumulations may be trapped in Devonian sandstone, limestone and mudstone units, as well as overlying younger sediments of the Mesozoic Eromanga Basin. Accumulations could be trapped by localised deposits of the Cooladdi Dolomite and other marine, terrestrial clastic and evaporite units around the basin. Migration of the expelled hydrocarbons may be restricted by overlying regional seals, such as the Wallumbilla Formation of the Eromanga Basin. Unconventional hydrocarbons are a likely target for the Adavale Basin with potential either for tight or shale gas in favourable areas from the Log Creek Formation and Bury Limestone.

MH370 Phase 1 150m Bathymetry datasets (GA-4421,GA-4422 & GA-4430)

On behalf of Australia, the Australian Transport Safety Bureau (ATSB) is leading search operations for missing Malaysian airlines flight MH370 in the Southern Indian Ocean. Geoscience Australia provided advice, expertise and support to the ATSB to facilitate bathymetric surveys, which were undertaken to provide a detailed map of the sea floor topography to aid navigation during the underwater search. Bathymetric data was acquired by multibeam sonar mounted on the hull of multiple vessels (GA survey reference: GA-4421, GA-4422 &amp; GA-4430). Bathymetric surveys were conducted from June 2014 to February 2017, collecting over 710,000 square kilometres of data in the search area and along transit lines (to and from the search area). This dataset allows exploration of the seafloor topography of bathymetry data at a resolution of 150 m across the search and transit areas of the Southern Indian Ocean. The dataset is overlain on a hillshade created from the 150m resolution bathymetry data. The hillshade was created with the parameters of point illumination azimuth at 45 degrees and altitude of 45 degrees.

This dataset is not to be used for navigational purposes.

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.

RV Investigator Voyage IN2026_V01 CTD Data

This record describes the CTD data collected on Investigator voyage IN2026_V01, titled: "Cook Ice Ecosystems and Sediments (COOKIES)." The voyage took place between January 02, 2026 and February 25, 2026 (AEST), departing from Hobart and returning to Hobart.

Data for 37 CTD deployments were acquired using the Sea-Bird SBE911 CTD unit #24, fitted with 36 twelve-litre bottles on the rosette sampler. Sea-Bird-supplied calibration factors were used to compute the pressures and preliminary conductivity values. CSIRO-supplied calibrations were applied to the temperature data. The data were subjected to automated QC to remove spikes and out-of-range values.

37 CTD casts were performed. A Benthic CTD camera was attached to the CTD to observe seafloor approximately ~4 m off bottom. Waiting 20 seconds after camera before firing bottom bottles as they use the same channels.

Cast summary:
• #1 – primary sensor channel had blockage, cleared ¾ on way down
• #2 – primary sensor blockage on way down
• #21, 22, 23 – yoyo casts to 600m – No bottles fired

The final conductivity calibration was based on a single deployment grouping. There were no changes to the sensors used throughout the voyage. The final calibration from the secondary sensor had a standard deviation (SD) of 0.00128 PSU, well within our target of ‘better than 0.002 PSU’. The standard product of 1-decibar binned averages were produced using data from the secondary sensors.

The dissolved oxygen data calibration fit had a SD of 0.8692μM. The agreement between the CTD and bottle data was good.
PAR, CDOM, transmissometer, Chlorophyll-A, and Backscatter sensors were also installed on the auxiliary A/D channels of the CTD.
The collected data were processed (quality-controlled), and subsequently archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).

Additional information regarding this dataset may be contained in the Voyage Summary and the Data Processing Report.

Land access and Indigenous engagement for Australian geoscience

The Exploring for the Future (EFTF) program is unmatched for the scale of geoscience data acquisition across northern Australia, covering 37 648 individual land parcels and 2.9 million km2. The scale of works has raised many new challenges for Geoscience Australia (GA) through the diverse range of field activities, and the numerous stakeholders from different social and cultural backgrounds, across multiple jurisdictions. Success of the program depended on the development and maintenance of a social licence to operate. This was broadly achieved for fieldwork activities through early engagement with stakeholders, including free, prior and informed consent. Here, we present two case studies of stakeholder engagement for facilitation of data collection: one focuses on broadscale, low-impact field activities associated with the AusAEM survey; and the other on Indigenous-focused engagement related to the Barkly Seismic Survey. Because of the complexity of project planning and managing such a large number of stakeholders, GA’s project governance team was expanded; it now includes a dedicated Land and Marine Access team and a commitment to adopt world-leading engagement practices. One practice is to consider impacts and benefits for all stakeholders—not just landholders—of field activities and data acquisition programs. This includes a plan for how the data are delivered back to the communities and stakeholders, and how information exchanges can be built into projects. The aim is for stakeholders to hold GA in the highest regard and understand the benefits to the Australian people, and ultimately their own communities, from the geoscientific data that GA produces.

Notes on Australian Lower Cretaceous palaeogeography

A small collection of marine Lower Cretaceous Mollusca from Mount Samuel area, central Western Australia, consists of six genera and seven species which are known from the Roma Formation beds of the Great Artesian Basin. It is suggested that a communicating seaway existed between the Great Artesian Basin and Mount Samuel area during Aptian times. Migration of marine organisms probably took place along a southern route through Officer and Eucla Basins, but may have possibly proceeded directly to the west from Rumbalara. It is also suggested that at the same time another seaway existed between Mount Samuel area and the Dampier Peninsula.The sediments of the Great Artesian Basin occur in two areas in the Northern Territory, viz, in the vicinity and to the east of Rumbalara, at the southern extreme of the Northern Territory where they are of Aptian age and are correlated with beds of Roma Formation in Queensland; and up to about one hundred miles south of the Gulf of Carpentaria, close to the Queensland border, where they are of Aptian and of Upper Albian age and can be correlated with the Roma and Tambo Formation beds of Queensland.

A New High-resolution Depth Model for the Terre AdÃ©lie and George V Shelf and Margin, East Antarctica

Abstract: The Collaborative East Antarctic Marine Census (CEAMARC) surveys to the Terre AdÃ©lie and George V shelf and margin highlight the requirement for a revised high resolution depth model that can be used as a spatial tool for improving physical models of the region. We have combined available shiptrack and multibeam bathymetry, coastline
and land topographic data to develop a new high-resolution depth model, called GVdem. GVdem spans an area 138Â°E to 148Â°E longitude and 63Â°S to 69Â°S latitude, with a choice of three ESRI grids with cell pixel sizes: 15 arcsec, 9 arcsec and 3.6 arcsec. The revised depth model is an improvement over previously available regional-scale grids, and highlights seabed physiographic detail not previously observed for this part of East Antarctica. In particular, the extent and complexity of the inner-shelf depressions are revealed and their relationship with large shelf basins and adjacent flat-topped banks.

Tectonic geomorphology and Holocene uplift rates of the Lae Urban Area, Papua New Guinea

The city of Lae is Papua New Guinea (PNG)’s second largest, and is the home of PNG’s largest port. Here, a convergence rate of ~50 mm/yr between the South Bismarck Plate and the Australian Plate is accommodated across the Ramu-Markham Fault Zone (RMFZ). The active structures of the RMFZ are relatively closely spaced to the west of Lae. However, the fault zone bifurcates immediately west of the Lae urban area, with one strand continuing to the east, and a second strand trending southeast through Lae City and connecting to the Markham Trench within the Huon Gulf.

 

The geomorphology of the Lae region relates to the interaction between riverine (and limited marine) deposition and erosion, and range-building over low-angle thrust faults of the RMFZ. Flights of river terraces imply repeated tectonic uplift events; dating of these terraces will constrain the timing of past earthquakes and associated recurrence intervals. Terrace riser heights are typically on the order of 3 m, indicating causative earthquake events of greater than magnitude 7.



Future work will expose the most recently active fault traces in trenches to assess single event displacements, and extend the study to the RMFZ north of Nadzab Airport. These results will inform a seismic hazard and risk assessment for Lae city and surrounding region.
