140 sediment samples from the Hawkesbury River estuary and fluvial sections were analyzed for texture, heavy metals, organochlorine pesticides, and nutrients. The dataset, hosted by the Australian Ocean Data Network, provides an integrated assessment of environmental impact from varied contaminant sources like urbanization, industry, and sewage. It was last updated on 2026-04-10.
A geological study of the Early Cretaceous Eumeralla Formation in the Otway Basin, southern Australia. Wireline-log analysis and sedimentary data discriminate three major basin-wide informal lithostratigraphic units, with a fourth unit present in the western basin. The Australian Ocean Data Network published this analysis, last updated on 2026-04-10.
The Australian Ocean Data Network provides a report on submarine volcanoes in the forearc region of the New Georgia Group, Solomon Islands. The description details specific volcanoes like Kavachi and Cook, including their composition, activity, and depth measurements. The dataset was last updated on 2026-04-10.
Manus Island in Papua New Guinea was surveyed for bauxite deposits during a geological reconnaissance. The report describes three nodular bauxite occurrences derived from volcanic rocks, with analyses showing high available alumina content. It was published by the Australian Ocean Data Network and last updated in April 2026.
Stable isotope and chemical studies of volcanic exhalations and thermal waters from the Rabaul caldera in Papua New Guinea, aggregated by the Australian Ocean Data Network. The data includes D/H and O18/O16 ratios, anion ratios, and trace metal contents (Fe, Mn, Zn) for waters in Matupi Harbour and Sulphur Creek, and fumarolic exhalations from Tavurvur and Rabalankaia volcanoes. The dataset was last updated on 2026-04-10.
The Tantangara and Brindabella 1:100,000 Sheet areas cover 5030 km² in New South Wales and the Australian Capital Territory, within the Lachlan Fold Belt. The dataset describes the geological history, including sedimentation, volcanism, and deformation events from the Ordovician through the Quaternary. It was published by the Australian Ocean Data Network and last updated on April 10, 2026.
259 km^2 Niue Island is a raised coral atoll with a peripheral ridge 60 m high and an internal basin 35 m high. The dataset, from the Australian Ocean Data Network, includes results from drilling, gravity and magnetic surveys, and electrical resistivity probes, describing a freshwater layer 40-170 m thick that decreases near the coast. It was last updated on 2026-04-10.
Hydrochemical data from a karstified limestone island in the central Pacific Ocean describes the evolution of freshwater to seawater in a brackish mixing zone. The dataset, sourced from the Australian Ocean Data Network, includes saturation indices for carbonate minerals like dolomite, calcite, and aragonite at specific total dissolved solids concentrations. It was last updated on 2026-04-10.
From 10 to 17 April 1997, the Australian Geological Survey Organisation (AGSO) conducted a swath-mapping cruise using the R.V. Melville. The survey aimed to map sea bed morphology and character off eastern Tasmania and in the Gippsland Basin using a SeaBeam 2000 multibeam sonar system, a magnetometer, and a gravity meter. The data was intended to aid tectonic, basin, and sedimentological studies, as well as the fishing industry and future geological sampling.
S-band radar measurements from the TU Delft transportable atmospheric radar TARA, placed at the remote sensing site in Cabauw. The dataset includes profiles of equivalent reflectivity factor, horizontal wind speed and direction, and vertical Doppler velocity. It is provided by the Ministerie van Binnenlandse Zaken en Koninkrijksrelaties under a CC-BY-4.0 license.
Approximately 6000 km of 2D seismic data were acquired in water depths of 1300-2500m east of Brisbane. Geoscience Australia and the RV Tangaroa collected this data between 2006 and 2007, integrating seismic, gravity, magnetic, and seafloor sampling to assess petroleum potential and marine habitats. The survey identified sediment depocentres up to 150 km long with up to 7 km of fill.
Global GeoTIFF raster maps show average annual landslide hazard and exposure of population, roads, and critical infrastructure. The eight files cover a 16-year period from 2001 to 2016 at 30 arc-second resolution, totaling approximately 20.3 GB. The data was produced by NASA using the Landslide Hazard Assessment for Situational Awareness (LHASA) model.
Geoscience Australia's GA302 marine survey acquired seismic velocity data during the summer of 2006/07 over the Capel and Faust Basins on the Lord Howe Rise. The survey was the final phase of the Big New Oil initiative, aiming to provide high-quality data to support petroleum prospectivity evaluation in frontier basins. The report describes seismic reflection, refraction, and potential field data from the survey.
Autonomous underwater gliders weighing 52kg collect repeated subsurface observations at a fraction of conventional costs. The Ocean Gliders Facility deploys Slocum and Seaglider types around Australia to study boundary currents and coastal ecosystems. Data is presented in delayed mode, with the record last updated in April 2026.
A 2026 paper from the Australian Ocean Data Network describes the Ivanhoe Block, a concealed basement ridge complex affecting groundwater flow in the New South Wales part of the Western Riverine Plain. The document analyzes the structure's role as a regional groundwater divide and its impact on salinity distribution, partitioning the plain into discharge and buffer zones. It assesses the risk of land salinisation for different zones, identifying the Balranald-Hatfield area as most at risk.
Laboratory experiments tested the effects of three abiotic stressors on the burrowing activity of the polychaete Capitella sp. 1. The study used temperature levels of 15, 21, and 32°C, salinity levels of 16, 22, 28, and 34, and three food availability treatments. Data was contributed by the Australian Ocean Data Network and last updated on 2026-04-10.
AGSO Cruise 125 collected swath-mapping and reflection seismic data during a 1994 voyage from Auckland to Adelaide aboard R.V. L'Atalante. The dataset includes maps at scales of 1:250,000, 1:1,000,000, and 1:100,000 covering transit routes and detailed survey areas off Tasmania. Maps feature ship tracks, sonar imagery, and bathymetric contours at 20, 25, and 50-meter intervals.
Evidence from 1967 onward indicates substantial horizontal compression across the Australian continent. The dataset includes focal mechanisms from eight earthquakes and in-situ stress measurements from sites including a 200 km north-south traverse near Meckering and Calingiri, and multiple sites in NSW tested during 1978-1979. Data was aggregated by the Australian Ocean Data Network.
M2SMNXEDI is a monthly data collection of extreme detection indices derived from NASA's MERRA-2 global atmospheric reanalysis. The dataset covers the period from January 1980 to the present and is computed based on a 1991-2020 climatology. It is produced by the NASA Global Modeling and Assimilation Office using the Goddard Earth Observing System Model.
