Geoscience Australia Data provides palynological analyses from four fully cored boreholes in the central west Murray Basin. The data includes analyses from the Woodlands-1, Manilla-1, Piangil West-2, and Hatfield-1 holes, augmented by reference to other sequences. The study aims to provide a biostratigraphic framework for geological factors related to groundwater, covering intervals from the Early Cretaceous to the Middle Miocene.
The Lord Howe Rise in the southwest Pacific is the focus of a deep stratigraphic drilling proposal to core Cretaceous and older sediments up to 2500 meters below the seafloor. Geoscience Australia and JAMSTEC submitted the proposal to the International Ocean Discovery Program in 2015, with drilling planned for 2019 or 2020. Preparations included 2D seismic surveys in 2016 and 2017 to map crustal structure and acquire geotechnical data.
UK fishing ports like Lowestoft and Great Yarmouth are the source for this archived collection of herring data from 1905 to 1990. The dataset likely contains biological measurements, scale growth analysis, survey records, and associated environmental observations. It is stored by the Government Digital Service as a substantial archive of hundreds of physical files, ledgers, and log books.
Approximately 6000 km of 2D seismic data were acquired in the Capel and Faust basins east of Brisbane between December 2006 and January 2007. The survey, conducted by Geoscience Australia and the RV Tangaroa, also collected gravity, magnetic, multibeam sonar, and sub-bottom profiler data, along with seafloor samples. These datasets are designed to define the region's petroleum prospectivity and inform marine environmental planning.
The Surat Basin in eastern Australia contains a 2500-meter-thick sequence of Jurassic and Cretaceous sediments. Geoscience Australia Data provides this geological description, which includes estimated petroleum reserves of 51 billion m³ of gas and 31 million m³ of oil from 1974. The description details sedimentary cycles, marine incursions, and volcanic activity from the Jurassic through the Miocene.
Three distinct high-energy fluvial depositional systems (A-C) are distinguished within the Lower Cretaceous Eumeralla Formation, with sandstone bodies reaching up to 70 meters thick. This dataset contains relationships, thicknesses, and palaeocurrent data from outcrops in the eastern Otway Basin, characterizing systems ranging from medial alluvial fans to distal braid plains. The model suggests volcanic detritus was sourced from infrarift complexes south of the present Aptian-Albian coastline.
Preliminary bathymetric and geomorphic mapping results from the RV Polarstern Expedition PS141 (EASI-3) in 2024. The dataset reveals submerged glacial features on the East Antarctic continental shelf, including iceberg scours and grounding zone wedges. It was prepared for the Australian Antarctic Research Conference in November 2024.
A geospatial dataset from Geoscience Australia describing the Ivanhoe Block, a concealed basement ridge complex affecting groundwater flow in the New South Wales part of the Western Riverine Plain. The data likely includes information on aquifer structures, groundwater salinity, and regional discharge zones, used to assess risks of land salinisation. The record was last updated on 2026-04-20.
Yass in the Southern Tablelands of New South Wales is the location for this dataset of fresh to brackish groundwaters. The data, provided by Geoscience Australia, describes groundwater chemistry from fractured bedrock aquifers beneath dryland salinity sites. The chemical composition is derived from processes including water-rock interaction, ion exchange, and microbially mediated reactions.
Geoscience Australia Data provides information on 18 dredge hauls recovered from the deepwater Gippsland Basin during the 1998 Franklin Cruise FR11/98. The dataset describes lithologies, ages, and paleo-environments of rocks and sediments, including Late Cretaceous volcanics and Neogene calcareous strata. The study was based on seismic reflection profiles and morphological features to site the dredges.
A detailed lithostratigraphic analysis of the Early Cretaceous Eumeralla Formation, a non-marine volcaniclastic unit in southern Australia. The dataset, from Geoscience Australia, identifies four basin-wide informal units and interprets their depositional environments. The analysis links sedimentary facies to Aptian-Albian sea-level changes and the influence of intrabasinal volcanism.
The Huon Gulf region in New Guinea features a semi-enclosed oceanic basin and the New Britain Trench, which is over 8000 metres deep. The dataset, published by Geoscience Australia, includes seismic reflection profiles and bathymetric soundings that reveal large-scale tectonic structures and sediment pathways. It describes the morphology of the continental shelf and submarine canyons, with data last updated on 2026-04-20.
AGSO (Australian Geological Survey Organisation) provides a format description for digital marine seismic and navigation data. The description details standard and optional trace header entries, including variations for unstacked data and conventions for shot point annotation and data polarity. The format is based on established geophysical standards and includes notes for data released before and after 1993.
Hundreds of files, ledgers, and log books from a fisheries data archive contain biological, survey, and market data on herring. The collection includes individual fish age, length, weight, maturity, vertebrae counts, and scale projection data. Associated environmental observations and spatial catch distribution information were collected by scientists at ports like Lowestoft and Great Yarmouth.
2016-2018 CTD depth profiles collected as part of a baseline assessment of marine water quality around Vanuatu in the South Pacific. The dataset supports the Commonwealth Marine Economies Programme and includes measurements from coastal waters around Efate and Tanna islands, focusing on the urbanized area of Port Vila. It was published by Cefas, UK, in 2020.
Geoscience Australia provides an updated collection of navigation data for marine seismic surveys in Australia. The data includes original navigation files, 2003 SNIP navigation files, and digitised survey track maps, cleansed and made available in KML and Shape file formats. Users should note the data is not final and may contain errors.
Geoscience Australia Data provides stable isotope and chemical analyses of thermal waters and volcanic exhalations from the Rabaul caldera in Papua New Guinea. The data includes D/H and O18/O16 ratios, anion ratios, and trace metal contents like Fe, Mn, and Zn. These measurements were used to investigate the origin of geothermal fluids, revealing a mixed source of meteoric and marine water.
Victoria provides the only well-exposed section across the southern Lachlan Fold Belt and easternmost Delamerides. The dataset details depositional, magmatic, and structural evolution from the Cambrian to the end of the Devonian, including the location of world-famous turbidite-hosted gold deposits and significant base-metal deposits in rift systems. It covers rock types from Late Proterozoic or Cambrian calc-alkaline arc volcanics and MORB-types to Silurian rift volcanics and sediments.
Geoscience Australia survey data identifies volcanic cones, flows, and sills on the seafloor of the northern Lord Howe Rise. The dataset includes features from at least two distinct volcanic ages: Miocene-Pliocene (approximately 4-7 Ma) and Eocene-Oligocene. Analysis is based on seismic data and swath bathymetry from a recent survey, with findings presented at the Australian Earth Sciences Convention in 2010.
The Murray Basin in Australia provides a record of vegetation and climate changes from the Tertiary to the early Pleistocene. The data, sourced from Geoscience Australia, describes a transition from high-precipitation forests to open woodlands and grasslands, with specific events like the Nothofagus phase. It examines the relationship between these changes, marine transgressions, and the historical absence of dryland salinity.
