2800 km of bathymetric and seismic reflection profiles covering about 110,000 km² of the Argo Abyssal Plain, analyzed by the Australian Ocean Data Network. The data reveals the tectonic and sedimentary history from the Late Jurassic to the present, including newly identified structural features like the Joey, Wombat, and Kivi Grabens. Five sedimentary sequences have been correlated with ODP Site 765 and DSDP Site 261, representing strata from the uppermost Jurassic to the Plio-Pleistocene.
AGSO digital seismic data adheres to the standard tape formats described by Barry et al. (1975). The dataset includes trace header mnemonics defined by AGSO and CogniSeis DISCO software, with variations for unstacked field data and optional entries like SHOT and SPN. It serves as a format description for marine seismic and navigation data, detailing conventions for shot point annotation and historical numbering changes.
Australia's remote offshore Capel and Faust basins are covered by approximately 6,000 km of industry-standard 2D seismic data acquired in late 2006 and early 2007. The data was acquired by Geoscience Australia as part of efforts to evaluate the resource potential of frontier basins. This record details the interpretation of that seismic data, complementing the release of digital interpretations in workstation formats.
Cambrian to Late Devonian geological data for Victoria, Australia, describing the evolution of the Lachlan Fold Belt and Delamerides. The dataset likely contains information on rock types, structural events, and mineral deposits, including world-famous turbidite-hosted gold and significant base-metal deposits. It is provided by the Australian Ocean Data Network via data.gov.au.
130 sampling stations were occupied during a 29-day research cruise in early 1987 aboard the R.V. Rig Seismic. Scientists from the Australian Ocean Data Network recovered Paleozoic to Quaternary rocks and sediments, alongside heatflow measurements, to assess petroleum potential. Headspace gas analyses indicate widespread thermogenic hydrocarbons across the Otway Basin and west Tasmanian margin.
Seismic refraction studies conducted near boreholes at Bewick, Hayman, and Heron Islands on the Great Barrier Reef, and across 124 profiles on six reefs in the Capricorn/Bunker Reefs. The data, hosted by the Australian Ocean Data Network, reveals a seismic discontinuity interpreted as the Holocene/pre-Holocene unconformity at depths of 8-23 meters. Results suggest modern reef growth forms are influenced by the shape of this pre-Holocene surface.
Interpretation of seismic refraction data from the southwestern coast of the Papuan Peninsula and the northwest Coral Sea provides insights into crustal composition and thickness. The dataset, sourced from the Australian Ocean Data Network, includes measurements of sediment thickness, P-wave velocities, and Moho depths across the region. It was last updated on 2026-06-27.
Nine peer-reviewed articles from the Australian Geological Survey Organisation's journal, published in volume 15, issue 3. The collection includes research on topics such as cleavage classification, Archaean gold mineralisation, and landscape evolution in Australia. The dataset is hosted by the Australian Ocean Data Network on data_gov_au.
Palynological analyses from four fully cored boreholes in the central west Murray Basin provide a biostratigraphic framework for geological factors related to groundwater. The study, augmented by analysis from other boreholes, covers sediments from the Early Cretaceous to the Middle Miocene. Data is provided by the Australian Ocean Data Network and was last updated on 2026-06, though the original study date is unspecified.
140 sediment samples from the Hawkesbury River system were analyzed for texture, heavy metals, organochlorine pesticides, and nutrients. The data, sourced from the Australian Ocean Data Network, reveals low contaminant levels in the main channel but elevated concentrations near urbanized and industrialized areas, particularly from sewage effluent. Sediments provide a long-term integrated assessment of contaminant sources and dispersion in this large, dynamic ecosystem.
From 10 to 17 April 1997, the Australian Geological Survey Organisation chartered the R.V. Melville to map the sea bed east and northeast of Tasmania. The cruise used a SeaBeam 2000 multibeam sonar system, a magnetometer, and a gravity meter to determine sea bed morphology and character for tectonic and sedimentological studies. Satellite gravity images and sparse existing profiles were used to plan the survey.
Recent geological mapping, drilling, and geophysical reassessment provide new details on the Lander Trough, a 300 km by 100 km crustal downwarp in Australia's Wiso Basin. The data distinguishes three rock sequences, including a thick (up to 800 m) Cambrian-Ordovician wedge that upgrades the area's petroleum potential. This dataset from the Australian Ocean Data Network, last updated in 2026, compiles findings on the trough's structure and its relation to the Alice Springs Orogeny.
Australian Institute of Marine Science (AIMS) materials for the study 'Multi-scale collapse of coral cover under climate change'. The collection includes simulation code, input generation scripts, and model outputs for Great Barrier Reef case studies. The associated paper is in review at Nature Communications.
The Murray Basin was forested throughout the Tertiary, transitioning to open woodlands and grasslands in the Plio-Pleistocene. This text-based dataset from the Australian Ocean Data Network describes step-like precipitation decreases from the late Oligocene and a distinct late Miocene-early Pliocene Nothofagus phase. It concludes that evidence for dryland salinity, as seen today, is absent throughout the Tertiary and early Pleistocene.
Fresh to brackish groundwaters ranging from 250 to 2250 mg/L occur in fractured bedrock aquifers beneath dryland salinity sites at Yass in the Southern Tablelands of New South Wales. The dataset, sourced via the Australian Ocean Data Network, describes the chemical composition of these waters, which originate from recent meteoric sources and represent various hydrochemical types. Chemical processes include water-rock interaction, ion exchange, and microbially mediated reactions with organic matter.
Niue Island is a raised coral atoll with an area of 259 km^2. The dataset, published by the Australian Ocean Data Network, contains findings from drilling, gravity, magnetic, and electrical resistivity surveys, describing the island's geology and freshwater lens configuration. It was last updated on 2026-06-27.
Australian Ocean Data Network presents a dataset on the tectonic geomorphology and Holocene uplift rates of the Lae Urban Area in Papua New Guinea. The data relates to the Ramu-Markham Fault Zone, where a convergence rate of ~50 mm/yr is accommodated, and includes analysis of river terraces indicating past earthquake events. This work was presented at the 2023 Australian Earthquake Engineering Society Conference.
A geological reconnaissance report from the Australian Ocean Data Network describes nodular bauxite deposits on Manus Island. The report details three separate surface occurrences, their volcanic origins, and favorable formation conditions of high temperature and rainfall. It includes chemical analyses showing high available alumina content and recommends further prospecting.
The southern McArthur Basin in Australia's Northern Territory contains mid-Proterozoic sedimentary rocks. The bulletin describes a sequence divided into four stratigraphic groups with thicknesses up to 4500 meters and ages dating to about 1690-125 Ma. It was published by the Australian Ocean Data Network and last updated in 2026.
Stable isotope and chemical data for thermal waters and fumarolic exhalations from the Rabaul caldera in Papua New Guinea. The dataset includes D/H and O18/O16 ratios, anion ratios, and trace metal contents like Fe, Mn, and Zn. It was published by the Australian Ocean Data Network and last updated in June 2026.
