130 sampling stations were occupied during a 29-day 1987 research cruise aboard the R.V. Rig Seismic. The cruise collected geological, geochemical, and heatflow data over the Otway and Sorell Basins off west Tasmania. Heatflow calculations from 20 stations and headspace gas analyses indicate widespread thermogenic hydrocarbons and mature source rocks.
An examination of coastal waterway flushing across Australia, classifying five major environment types based on the Sf/So salinity ratio. The dataset likely contains derived parameters like freshwater residence time, used as a proxy for dissolved anthropogenic input. It was published by Geoscience Australia Data and last updated on 2026-04-30.
Geoscience Australia Data provides a paleoecological analysis of the Murray Basin from the Tertiary into the early Pleistocene. The description details major vegetation transitions, including a shift from widespread rainforest to eucalypt wet sclerophyll forest in the mid-late Miocene and a distinct late Miocene-early Pliocene Nothofagus phase. It concludes that evidence for salinity during this period is only associated with marine environments, with no indication of modern dryland salinity.
The central west Murray Basin in Australia is the focus of this palynological analysis from four fully cored boreholes. The dataset likely contains pollen and dinoflagellate data used to establish a biostratigraphic framework for geological factors related to groundwater. The study, augmented by analysis from other boreholes, was produced by Geoscience Australia Data.
Geoscience Australia Data provides a dataset from laboratory experiments examining the effects of temperature, salinity, and food availability on the burrowing activity of the polychaete Capitella sp. 1. The data includes measurements of burrow depth, area of activity, and associated sediment chemistry using pH and O2 fluorosensors. The dataset was last updated on 2026-04-30.
2500 meters of Jurassic and Cretaceous sediments form the Surat Basin, containing significant fossil fuel resources. Geoscience Australia Data provides this geological description, which includes estimates of 51 billion cubic meters of gas and 31 million cubic meters of oil reserves from 1974. The report details depositional environments, structural features, and the basin's geological evolution up to its current stable state.
Volume 11, Issue 1 of the BMR journal contains 12 research articles on Australian earth sciences. The issue includes studies on earthquake history, continental seismic mapping, Cambrian trilobites, and petroleum potential. It was published by Geoscience Australia Data and last updated in April 2026.
Seismic refraction data from 124 profiles conducted on six reefs in the Capricorn/Bunker group of the Great Barrier Reef. The dataset, provided by Geoscience Australia, correlates seismic discontinuities with borehole data to study the pre-Holocene surface beneath modern reefs. The data was last updated on 2026-04-30.
Gippsland Basin, Australia, was the site of 18 dredge hauls during the 1998 Franklin Cruise FR11/98. The study recovered volcanic, volcaniclastic, and calcareous rocks, providing lithological and paleo-environmental information for the deepwater basin. The dataset likely contains information on rock types, ages, and sample locations from seismic-guided dredging.
Geochemical data for thermal waters and fumarolic exhalations from the Rabaul caldera in Papua New Guinea. The dataset includes stable isotope (D/H and O18/O16) ratios, anion ratios, and trace metal contents (Fe, Mn, Zn) used to investigate water origins. It was published by Geoscience Australia and last updated on 2026-04-30.
The CAR FIREACE Arctic Ice and Cloud Radiation BRDF V2 dataset consists of satellite observations from the CAR instrument. It provides bidirectional reflectance factor values across varying spectral bands to study Arctic cloud-radiation feedbacks and surface energy budgets. The data was produced by the National Aeronautics and Space Administration and last updated in March 2026.
June 2007 observations from the Cloud and Land Surface Interaction Campaign (CLASIC) in the Southern Great Plains of the United States. The data set consists of measurements from the CAR instrument aboard a Sky Research Jetstream-31 aircraft, providing bidirectional reflectance factor values at varying spectral bands. It was collected by the National Aeronautics and Space Administration.
DISCOVER-AQ, a NASA Earth Venture mission, collected bidirectional reflectance distribution function (BRDF) measurements over Colorado in 2014. The CAR instrument aboard a NASA P-3 aircraft obtained these observations over agricultural and urban areas. This data set includes bidirectional reflectance factor values at varying spectral bands to support satellite monitoring of air pollution.
The Early Cretaceous Eumeralla Formation comprises four informal lithostratigraphic units identified through wireline-log analysis and sedimentary data. Geoscience Australia Data published this analysis, which was last updated on 2026-04-30. The units represent depositional environments ranging from coal swamps and flood plains to freshwater lakes and high-energy stream channels.
140 sediment samples from the Hawkesbury River system between Windsor and Broken Bay were analyzed for texture, heavy metals, organochlorine pesticides, and nutrients. The dataset, provided by Geoscience Australia, offers a long-term integrated assessment of environmental impact in a large dynamic ecosystem. It reflects land use patterns, with low contaminant levels in the main channel and elevated concentrations near urban, industrial, and recreational areas.
About 2800 km of bathymetric and seismic reflection profiles cover 110,000 km² of the Argo Abyssal Plain in the eastern Indian Ocean. The data reveal newly identified structural features like the 400-450 km long Joey Graben and document tectonic evolution from the Late Jurassic to the Miocene. Five sedimentary sequences have been correlated with lithology from ODP Site 765 and DSDP Site 261.
Geoscience Australia Data provides evidence on horizontal compressive stress in the Australian continent. The dataset includes focal mechanism determinations from eight earthquakes since 1967 and in-situ stress measurements from mines, tunnels, and shallow over-coring tests. Measurements were taken along a 200 km north-south traverse and at several sites in New South Wales during 1978-1979.
Geoscience Australia survey data identifies volcanic cones, flows, and sills on the seafloor of the offshore Lord Howe Rise Capel-Faust region. Analysis of seismic data and swath bathymetry reveals at least two distinct ages of volcanism: Miocene-Pliocene (approx. 4-7 Ma) and Eocene-Oligocene features. The survey area includes the Gifford Guyot and examines potential seamount chain alignments.
Geoscience Australia provides an updated collection of navigation data for marine seismic surveys conducted in Australian waters. The collection includes original navigation files, 2003 SNIP navigation files, and digitized survey track maps, cleansed and made available in KML and Shapefile formats. Users should note the data is not final and may contain errors.
A geological reconnaissance report from Geoscience Australia details nodular bauxite deposits observed in three localities on Manus Island. The report describes the deposits' formation from recent volcanic rocks overlying a Miocene or younger basement and includes analyses showing high available alumina content. The data is provided in PDF and HTML formats and was last updated on 2026-04-30.
