Nauru Island's karstified limestone hosts a thin freshwater layer over a thick brackish water mixing zone where salinity increases gradationally to seawater at about 70 meters below sea level. Hydrochemical data, likely from Geoscience Australia, shows groundwater evolves from HCO3-Ca-Mg type to seawater, with saturation indices for carbonate minerals like dolomite and calcite increasing with salinity. The dataset distinguishes between open and closed system chemical evolution trends based on the partial pressure of CO2.
Geoscience Australia Data provides a paleoenvironmental analysis of the Murray Basin from the Tertiary to the early Pleistocene. The description details vegetation shifts from rainforest to open woodlands and changes in precipitation, with specific events like the Nothofagus phase. It examines the relationship between these changes, marine transgressions, and the historical absence of dryland salinity.
Geoscience Australia Data provides a study of the Early Cretaceous non-marine volcaniclastic Eumeralla Formation in the Otway Basin. The analysis identifies four basin-wide lithostratigraphic units and interprets their depositional environments, from coal swamps to high-energy stream channels. The dataset, last updated on 2026-03-25, includes interpretations linking sedimentation to Aptian-Albian sea-level changes and intrabasinal volcanism.
NOAA's historical hurricane data spans 182 years, from 1842 through 2024. This feature layer, sourced from the International Best Track Archive for Climate Stewardship (IBTrACS), includes storm positions, intensities, and attributes. It is hosted by the Myanmar Information Management Unit and was last updated in March 2026.
Evidence from earthquake focal mechanisms and in-situ stress measurements indicates substantial horizontal compression across the Australian continent. The dataset includes reliable focal mechanism determinations from eight earthquakes since 1967 and in-situ measurements from multiple sites, including a 200 km north-south traverse near the Meckering and Calingiri epicenters. Data was collected by Geoscience Australia Data, with the record last updated on 2026-03-25.
Geoscience Australia Data provides stable isotope and chemical data for thermal waters and volcanic exhalations from the Rabaul caldera in 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 2026-03-25.
Manus Island in Papua and New Guinea is the subject of a geological reconnaissance report describing nodular bauxite deposits. The report details three separate surface occurrences derived from volcanic rocks, likely of Miocene or younger age, and includes chemical analyses of individual nodules. The document was published by Geoscience Australia Data and was last updated on 2026-03-25.
Two dry-season surveys of Keppel Bay and Casuarina Creek collected data on biogeochemical properties of the water column and underlying sediments. The dataset was published by Geoscience Australia Data and was last updated in March 2026. It was created to understand sediment, nutrient, and agrochemical pathways in macrotidal estuaries facing ecological change from agricultural activities.
Interpretation of seismic refraction data from the southwestern coast of the Papuan Peninsula and the northwest Coral Sea. The dataset includes sediment thicknesses of 1 to 10 km, P-wave velocities of 6.07 km s^-1 and 6.9 km s^-1, and Moho depths ranging from 19 to 29 km. It was published by Geoscience Australia Data.
Geoscience Australia survey data identifies volcanic features like cones, flows, and sills on the seafloor of the Lord Howe Rise's Capel-Faust region. Analysis of seismic and bathymetry data reveals at least two distinct volcanic ages: Miocene-Pliocene (approx. 4-7 Ma) and Eocene-Oligocene. The data was presented at the Australian Earth Sciences Convention in July 2010.
Geoscience Australia Data provides a geological and geochemical dataset covering 5,030 km² in the Tantangara and Brindabella 1:100,000 sheet areas of New South Wales and the Australian Capital Territory. The data describes the region's complex geological history, including sedimentation from the mid-Ordovician to the Middle Devonian, multiple volcanic and intrusive events, and subsequent deformation. The dataset was last updated on 2026-03-25.
A 2023 study of the Ramu-Markham Fault Zone near Lae, Papua New Guinea, presented at the Australian Earthquake Engineering Society Conference. The data likely contains geospatial information on fault traces, river terraces, and uplift rates to inform seismic hazard assessment. It was published by Geoscience Australia Data and last updated in March 2026.
Geoscience Australia provides an updated collection of navigation data for marine seismic surveys in Australian waters. The data is based on the UKOOA-standard P190 navigation file format and is available in both KML and Shapefile formats. Users should note the data is not final and may contain errors, as the cleansing process is ongoing.
A 2026 report from Geoscience Australia describes submarine volcanoes and volcanic activity in the forearc region of the New Georgia Group, Solomon Islands. The description includes specific volcanoes like Kavachi and Cook, with details on their composition, depth, and historical activity reports. It highlights the region's poor bathymetric survey coverage and the need for modern mapping.
Eleven PIRATA buoy stations provide in-situ validation for this daily, 0.05-degree resolution sea surface temperature dataset covering the Tropical Atlantic from 45°S to 15°N and 70°W to 15°W. The Oceanographic Modeling and Observation Network (REMO) at LMA/UFRJ operationally produces this Level 4 analysis by blending infrared AVHRR and microwave TMI satellite data using a Barnes optimal interpolation technique to create a daily cloud-free product. This dataset is part of the international Group for High Resolution Sea Surface Temperature (GHRSST) initiative.
A geological dataset describing the Ivanhoe Block, a concealed basement ridge complex affecting groundwater systems in the New South Wales Riverine Plain. The data likely contains information on aquifer structures, flow deflection, and strata-bound salinity used for a three-fold subdivision of the Renmark Group. The dataset originates from Geoscience Australia and was last updated in March 2026.
Groundwater samples from fractured bedrock aquifers beneath dryland salinity occurrences at Yass in the Southern Tablelands of New South Wales. The dataset, provided by Geoscience Australia Data, describes fresh to brackish waters with total dissolved solids ranging from 250 to 2250 mg/L. The chemical composition is derived from processes including water-rock interaction, ion exchange, and microbially mediated reactions.
2002 to 2009 data from the European Space Agency's Envisat satellite, carrying the Advanced Along-Track Scanning Radiometer (AATSR). This dataset provides high-accuracy global skin sea surface temperature (SST) measurements, processed according to GHRSST standards, to support a multi-decade climate record. It is produced by the European Space Agency and distributed by NOAA and NASA.
Between December 2006 and January 2007, Geoscience Australia acquired approximately 6000 km of 2D seismic data in the Capel and Faust basins, located 800 km east of Brisbane. A 2007 marine reconnaissance survey by RV Tangaroa added gravity, magnetics, multibeam sonar, sub-bottom profiler, and seafloor sample data. These datasets are designed to define the region's petroleum prospectivity and inform marine environmental planning.
AGSO Cruise 125 collected swath-mapping and reflection seismic data in the Tasman Sea off Tasmania in 1994 using the French research vessel L'Atalante. The dataset includes maps at scales of 1:250,000, 1:1,000,000, and 1:100,000, covering ship tracks, sonar imagery, and bathymetric contours. The data was aggregated by Geoscience Australia and last updated on the platform in March 2026.
