140,000 square kilometers of the Wiso Basin in Australia's Northern Territory are documented in this hydrogeological inventory. The dataset, hosted by the Australian Ocean Data Network, groups descriptive attributes into themes like geology, groundwater, and land use. Its last update was recorded on 2026-05-04.
A study area from 112°E to 122°E seaward of the Totten Glacier and Sabrina Coast in East Antarctica. The dataset, published in Marine Geology in 2020, describes submarine canyons and ridges formed by mixed contourite-turbidite systems, indicating sediment accretion and mass movement processes. These features are proposed as prime locations for sampling sedimentary records of glacier-ocean interaction.
Geoscience Australia Data collected geological, geochemical, and heatflow data during a 29-day research cruise in early 1987. Scientists aboard R.V. Rig Seismic occupied 130 sampling stations using dredges, corers, grabs, and a heatflow probe across the Otway Basin and west Tasmanian margin. The samples include Paleozoic volcanics, Cretaceous to Tertiary sedimentary rocks, and Quaternary sediments, all taken along seismic profiles.
Daily volcanic gas emissions from Costa Rica's Rincón de la Vieja volcano include tons of SO2, CO2, and H2S molar ratios. Measurements from May 2023 to May 2024 were collected by permanently installed DOAS and Multi-GAS instruments operated by OVSICORI-UNA. A data gap between December 2023 and March 2024 resulted from a malfunction of the Multi-GAS instrument's SO2 sensor.
Geoscience Australia Data provides hydrochemical data from a groundwater-seawater mixing zone on Nauru Island. The dataset describes the chemical evolution of freshwater to seawater, including saturation indices for carbonate minerals like dolomite, calcite, and aragonite at specific total dissolved solids levels. It was last updated on 2026-05-14.
A geological bulletin describes the stratigraphy and structure of the southern McArthur Basin in Australia's Northern Territory. The sequence is divided into four stratigraphic groups, including the Tawallah Group (~4500 m thick) and the combined McArthur and Nathan Groups (~5500 m thick). The data was published by Geoscience Australia and was last updated on 2026-05-14.
A geospatial dataset describes the hydrogeology of Niue Island, a raised coral atoll in the South Pacific Ocean with an area of 259 km². The data likely contains results from drilling, gravity and magnetic surveys, and electrical resistivity depth probes, indicating freshwater layer thickness and aquifer properties. It was published by Geoscience Australia Data and last updated in May 2026.
Eighteen dredge hauls recovered from the deepwater Gippsland Basin during the 1998 R/V Franklin cruise FR11/98 provide lithological and age data for this region. The collection includes volcanics, volcaniclastics, and calcareous sediments spanning from the Late Cretaceous to the Holocene. Geoscience Australia Data published this information to characterize the little-known deepwater basin.
AGSO Cruise 125, conducted by Geoscience Australia, collected swath-mapping and reflection seismic data in the Tasman Sea off Tasmania in 1994 using the French research vessel L'Atalante. The cruise produced a suite of bathymetric maps at scales from 1:1,000,000 to 1:100,000, covering transit routes and detailed survey areas. Data includes ship tracks, sonar imagery, and contour maps.
Geoscience Australia Data provides an overview of coastal waterway flushing across Australia. The dataset likely contains quantitative parameters like the Sf/So salinity ratio and freshwater residence time estimates, derived from salt and water mass balances. It identifies five major coastal environment types based on geographic and temporal climate forcing factors.
Geoscience Australia survey data identifies volcanic features on the seafloor of the offshore Lord Howe Rise Capel-Faust region. The data includes at least two distinct ages of volcanism: Miocene-Pliocene (approximately 4-7 Ma) cones and Eocene-Oligocene volcanic edifices. Presented at the Australian Earth Sciences Convention in July 2010.
Laboratory experiments from Geoscience Australia Data examine the effects of abiotic stressors on infaunal burrowing. The data likely contains results from tests on the polychaete Capitella sp. 1 under controlled temperature (15, 21, and 32°C), salinity (16, 22, 28, and 34), and food availability (low, moderate, high) conditions, with associated sediment chemistry measurements. The dataset was last updated on 2026-05-14.
Geoscience Australia Data provides a report on submarine volcanoes in the forearc region of the New Georgia Group, Solomon Islands. The description details specific features like Kavachi, Kana Keoki, and Cook volcano, including their composition, activity, and depths. The data was last updated on 2026-05-14.
Geoscience Australia Data provides stable isotope and chemical data for thermal waters and volcanic exhalations in the Rabaul caldera, Papua New Guinea. The dataset includes D/H and O18/O16 ratios, anion ratios, and trace metal contents used to investigate the origin of geothermal fluids. It was last updated on 2026-05-14.
140 sediment samples from the Hawkesbury River system in Australia were analyzed for texture, heavy metals, organochlorine pesticides, and nutrients. The dataset, provided by Geoscience Australia Data, reflects environmental impacts from land use, urbanization, and sewage discharge. Sediment analysis provides a long-term integrated assessment of contaminant sources and dispersion in this large coastal catchment.
Geoscience Australia provides a 2D animation illustrating groundwater sampling techniques. The animation shows simplified equipment, measurement processes, and how scientists use the resulting data. It was last updated on 2026-06-10 and is part of a series of Field Activity Technique Engagement Animations.
A paleoenvironmental analysis describes vegetation and climate changes in the Murray Basin from the Tertiary to the early Pleistocene. The description details step-like decreases in precipitation from the late Oligocene and specific floral events like the Nothofagus phase in the late Miocene-early Pliocene. It was published by Geoscience Australia Data and last updated in May 2026.
Groundwater samples from fractured bedrock aquifers beneath dryland salinity occurrences in the Yass region of New South Wales. The data, provided by Geoscience Australia, likely contains measurements of major cations and anions, with salinity ranging from fresh to brackish (250 to 2250 mg/L). The chemical composition is described as resulting from water-rock interaction, ion exchange, and microbial processes.
The Otway Basin in southern Australia contains the Early Cretaceous Eumeralla Formation, a volcaniclastic sedimentary sequence. Geoscience Australia Data analyzed wireline logs and sedimentary data to define four basin-wide lithostratigraphic units, interpreting their depositional environments from coal swamps to high-energy stream channels. The data suggests a single integrated drainage system persisted in the basin from the Aptian to the late Albian, influenced by sea-level changes and intrabasinal volcanism.
124 seismic refraction profiles were completed on six reefs in the Capricorn/Bunker Reefs area. The dataset, from Geoscience Australia Data, contains results from studies near boreholes at Bewick, Hayman, and Heron Islands. It shows a seismic discontinuity at depths of 8-23 meters, equated with the Holocene/pre-Holocene unconformity.
