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.
Daily cloud-free foundation sea surface temperature analysis for the Mediterranean Sea, produced operationally by Ifremer/CERSAT. The dataset merges infrared and microwave observations from multiple satellite sensors, including AVHRR, AATSR, SEVIRI, AMSRE, TMI, and GOES, using optimal interpolation on a 0.02-degree grid. It is a GHRSST Level 4 product supported by the European Commission and supersedes the previous regional analysis.
A 1987 marine research cruise collected geological, geochemical, and heat flow data from 130 sampling stations in the Otway and Sorell Basins off western Tasmania. The cruise recovered rock samples ranging from Palaeozoic to Quaternary age and conducted headspace gas analyses on sediment cores. The data, provided by Geoscience Australia, was gathered to assess the petroleum potential of the region.
Eastern Tasmania and the Gippsland Basin were surveyed from 10 to 17 April 1997 by the Australian Geological Survey Organisation. The R.V. Melville used a SeaBeam 2000 multibeam sonar, a magnetometer, and a gravity meter to map sea bed morphology and character. The data was intended to aid tectonic, basin, and sedimentological studies, as well as the fishing industry.
A report describing velocity data from the GA302 marine seismic survey conducted in the summer of 2006/07. The data includes seismic reflection, refraction, and potential field measurements over the Capel and Faust Basins on the Lord Howe Rise. The survey was part of the Australian Government's Big New Oil initiative to support frontier petroleum exploration.
Geoscience Australia Data provides a geological bulletin describing the mid-Proterozoic sedimentary rocks of the southern McArthur Basin in Australia's Northern Territory. The description details four stratigraphic groups with thicknesses up to 12 kilometers, rock types including quartz sandstone, dolostones, and volcanics, and structural features like the Batten Fault Zone. The dataset was last updated on 2026-03 25.
Laboratory experiments measured the burrowing activity of the polychaete Capitella sp. 1 under controlled abiotic stressors. The dataset likely contains results from tests at three temperatures (15, 21, and 32°C), four salinity levels (16, 22, 28, and 34), and three food availability treatments. Data from Geoscience Australia, last updated in March 2026, examines how these stressors affect sediment chemistry via bioturbation.
AGSO Journal volume 15 number 3 contains nine peer-reviewed scientific articles on Australian earth sciences. The articles cover topics including cleavage classification, gold mineralisation, geological mapping, earthquake forecasting, landscape evolution, marine communities, and paleontological correlations. The content is published by Geoscience Australia Data and was last updated in March 2026.
Delaware data on advisories issued for water quality problems in selected recreational water areas. The dataset includes advisory details such as start and end dates, reasons, and types. It is provided by data.delaware.gov and was last updated in April 2026.
Daily sea surface temperature analysis from 2002 onward, produced operationally by Ifremer/CERSAT in France. This dataset provides a cloud-free foundation sea surface temperature field at approximately 2 km resolution for the Galapagos Islands and Eastern Central Pacific region. It is generated by merging and optimally interpolating calibrated microwave and infrared observations from multiple satellite sensors.
140 sediment samples from the Hawkesbury River system were analyzed for texture, heavy metals (Cd, Co, Cu, Fe, Mn, Ni, Pb, Zn), organochlorine pesticides (DDT, DDD, DDE, HCB, chlordanes, aldrin, lindane, heptchlor, H-epoxide, dieldrin), and nutrients (organic P, available P, inorganic P, total P, TOC, TKN). The data, sourced from Geoscience Australia, provides a long-term integrated assessment of environmental impact from sources like urbanization, industry, and sewage. It was last updated on 2026-03-25.
Seismic refraction studies conducted near boreholes at Bewick, Hayman, and Heron Islands on the Great Barrier Reef. The dataset includes 124 profiles from six reefs in the Capricorn/Bunker group, measuring a seismic discontinuity at depths of 8-23 meters.
