The Australian Ocean Data Network provides a geological description of the Surat Basin in Queensland. The dataset describes 2500 meters of Jurassic and Cretaceous sediments, detailing depositional environments and structural features. It includes 1974 estimates of petroleum reserves, citing 51 billion m3 of gas and 31 million m3 of oil, and notes considerable reserves of bituminous coal and oil shale.
AGSO Journal vol.15 no. 3 is a collection of nine peer-reviewed scientific articles published by the Australian Geological Survey Organisation. The articles cover topics including cleavage classification, Archaean gold mineralisation, geological mapping, earthquake seismicity, landscape evolution, marine benthic communities, foraminiferid correlations, conodont apparatus structure, and basaltic volcanism. The dataset is provided by the Australian Ocean Data Network and was last updated on 2026-06-04.
Data from Nauru Island, a karstified dolomitic limestone island in the central Pacific Ocean, describes the hydrochemistry of a freshwater layer overlying a brackish water mixing zone. The dataset, hosted by the Australian Ocean Data Network, likely contains measurements of groundwater salinity, saturation indices for carbonate minerals, and partial pressure of CO2. It was last updated on 2026-06-04.
An overview of coastal waterway flushing across Australia, classifying five major environmental types based on the Sf/So salinity ratio. The dataset likely contains geographic and temporal salinity data used to estimate freshwater residence time, a proxy for dissolved anthropogenic input. It was published by the Australian Ocean Data Network.
Seismic refraction studies conducted near shallow boreholes at Bewick, Hayman, and Heron Islands, and across 124 profiles on six reefs in the Capricorn/Bunker group. The data, sourced from the Australian Ocean Data Network, reveals a seismic discontinuity at depths of 8-23 meters, equated with the Holocene/pre-Holocene unconformity. Results show the pre-Holocene surface morphology influences modern reef growth forms, challenging a latitudinal genetic sequence model.
140 sediment samples from the Hawkesbury River system were analyzed for texture, heavy metals, organochlorine pesticides, and nutrients. The dataset, hosted by the Australian Ocean Data Network, provides a long-term integrated assessment of environmental impact in a large dynamic ecosystem. Sediment contaminant levels reflect varied land use, from low-intensity areas to zones impacted by urbanization, industry, and sewage discharge.
Greenland Ice Sheet outlet glaciers are mapped in this dataset of 50-meter resolution digital elevation models (DEMs). The data were collected by NASA's airborne GLISTIN-A radar between 2016 and 2019, comprising 81 repeated swaths around the ice sheet periphery. This Level 3 product is processed for consistency to facilitate analysis of year-to-year glacier surface elevation changes.
AGSO Cruise 125 collected swath-mapping and reflection seismic data off Tasmania and during transits between New Zealand and Australia in 1994. The dataset includes bathymetric maps at scales of 1:250,000, 1:1,000,000, and 1:100,000, produced from the SIMRAD EM12D system on the R.V. L'Atalante. The Australian Ocean Data Network hosts the report and associated map files.
AGSO Formats for Marine Seismic and Navigation Digital Data is a technical specification document from the Australian Ocean Data Network. It details the trace header format for digital seismic data, adhering to standards from Barry et al. (1975) and incorporating AGSO-specific mnemonics used in DISCO software. The document explains critical fields like SHOT and SPN, and clarifies a major numbering convention change for data released prior to 1993.
Fresh to brackish groundwaters ranging from 250 to 2250 mg/L occur in fractured bedrock aquifers beneath dryland salinity sites in the Southern Tablelands of New South Wales. The dataset, provided by the Australian Ocean Data Network, describes the chemical composition of these waters, which originate from recent meteoric sources and are shaped by water-rock interaction, ion exchange, and microbial processes. The data was last updated on 2026-06-04.
Interpretation of seismic refraction data from the southwestern coast of the Papuan Peninsula and the northwest Coral Sea. The dataset includes sediment thickness, P-wave velocities, and Moho depth, published by the Australian Ocean Data Network and last updated in June 2026.
Eight earthquake focal mechanisms and in-situ stress measurements from mines, tunnels, and quarry floors across Australia indicate substantial horizontal compression in the continent's crust. Measurements from a 200 km north-south traverse near the 1968 Meckering and 1970 Calingiri earthquakes show a high regional compressive stress oriented about 77°E of N, with values ranging from 4 MPa to 23 MPa. The dataset, sourced from the Australian Ocean Data Network, includes results from sites tested in 1978-1979 in New South Wales, showing varying principal stress orientations across different regions.
A 2026 dataset from the Australian Ocean Data Network describes submarine volcanoes in the forearc region of the New Georgia Group, Solomon Islands. It includes details on specific features like Kavachi, Kana Keoki, and the elusive Cook volcano, reporting on their composition, activity, and bathymetric surveys. The data suggests the region is very poorly surveyed, highlighting a need for further mapping.
Laboratory experiment data examines the effects of temperature, salinity, and food availability on the burrowing activity of the polychaete Capitella sp. 1. The dataset includes measurements of burrow depth, area of activity, and associated sediment chemistry using pH and O2 fluorosensors. Results show burrowing behavior and sediment solute exchange are affected by environmental stressors.
Twelve research articles from the BMR Journal of Australian Geology and Geophysics volume 11, issue 1, constitute this collection. Articles cover topics including a century of earthquakes in the Dalton-Gunning region, probabilistic earthquake risk maps for Tasmania, Australia's petroleum potential, and Upper Cambrian trilobites in New South Wales. The dataset provides a snapshot of Australian geological and geophysical research from the late 20th century.
130 sampling stations from a 1987 research cruise provide geological, geochemical, and heatflow data from the Otway and Sorell Basins. Heatflow calculations from 20 stations indicate the zone of thermal maturation for hydrocarbons is 2-4 km deep. Headspace gas analyses show widespread thermogenic hydrocarbons, suggesting mature source rocks are common in the region.
Lord Howe Rise velocity data acquired during the 2006/07 summer survey GA302. The report describes seismic reflection, refraction, and potential field data collected by Geoscience Australia. This work aimed to improve confidence in sediment thickness estimation for frontier petroleum province evaluation.
A textual scientific report details the vegetation and climate evolution of the Murray Basin from the Tertiary to the early Pleistocene. The description likely contains paleoecological data derived from pollen analysis, tracing shifts from rainforest to eucalypt forests and grasslands. It was published by the Australian Ocean Data Network and last updated in June 2026.
Late Triassic to Cainozoic geological samples were dredged from the northern Exmouth Plateau margin in water depths of 2000-5600 meters by research vessels R.V. Sonne and R.V. Rig Seismic. The dataset, provided by the Australian Ocean Data Network, includes detailed petrography and microfacies analysis defining seven major lithofacies associations. These analyses enable correlation with coeval platform carbonates in the Alps and Mediterranean area of the Tethys ocean.
Recent geological mapping, stratigraphic drilling, and geophysical reassessment provide information on the Lander Trough in the Wiso Basin. The data describes three rock sequences, including a thick Cambrian-Ordovician sedimentary wedge, and assesses the trough's dimensions and petroleum potential. The dataset is hosted by the Australian Ocean Data Network and was last updated in 2026.
