Photographs document regional study areas in Alabama, Georgia, and Oklahoma, USA, captured during the 2003 Soil Moisture Experiment (SMEX03). The dataset was produced by the National Aeronautics and Space Administration to support ground validation for satellite-based soil moisture measurements. It provides visual context of land surface conditions concurrent with remote sensing data collection.
A dataset from the Australian Ocean Data Network describes the hydrochemistry of a groundwater-seawater mixing zone on Nauru Island, a karstified dolomitic limestone island in the central Pacific Ocean. It details the evolution of freshwater bicarbonate-calcium-magnesium groundwater to seawater, with saturation indices for carbonate minerals increasing with salinity. The dataset was last updated on 2026-04-16.
AGSO digital seismic data formats adhere to standards from Barry et al. (1975). Trace header mnemonics are based on CogniSeis DISCO software and AGSO definitions. The data includes variations for unstacked data, static corrections, and optional entries like SHOT or SPN.
A quantitative parameter, Sf/So, identifies five major types of coastal environment around Australia based on salinity ratios. The Australian Ocean Data Network provides this overview, which uses a general equation of salt and water mass balances to estimate freshwater residence time. Geographic and temporal variation in climate forcing factors exert major controls on residence time and flushing of Australian coastal environments.
Jurassic and Cretaceous sediments up to 2500 meters thick form the Surat Basin in eastern Australia. The geological description details fluvial deposition, marine incursions, volcanic activity, and subsequent erosion and weathering. It includes a 1974 resource estimate of 51 billion cubic meters of gas and 31 million cubic meters of oil, alongside coal and oil shale reserves in the Walloon Coal Measures.
The Riverine Plain of New South Wales in the central Murray Basin contains the Ivanhoe Block, a concealed basement ridge complex affecting groundwater flow. The dataset likely contains information on aquifer structures, groundwater salinity distribution, and risk zones for land salinisation. It is provided by the Australian Ocean Data Network via data.gov.au.
18 dredge hauls of rocks and sediments recovered from the deepwater Gippsland Basin during the 1998 Franklin Cruise FR11/98. The study provides lithology, age, and paleoenvironment information for the basin, categorizing samples into Late Cretaceous volcanics, volcaniclastics, Neogene calcareous sediments, and Quaternary calcareous oozes. The data was collected by the Australian Ocean Data Network.
Geoscience Australia's seismic marine survey GA302 acquired velocity data during the summer of 2006/07 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 basin acreage release. The report reviews seismic reflection, sonobuoy refraction, and stacking velocity data.
In early 1987, scientists aboard R.V. Rig Seismic conducted a 29-day research cruise over the Otway Basin and Sorell Basin of the west Tasmanian margin. The Australian Ocean Data Network provides data from 130 sampling stations using dredges, corers, grabs, and a heatflow probe. The cruise aimed to provide new geological, geochemical, and heatflow data in an area with considerable petroleum potential.
Geoscience Australia developed spatial datasets modeling natural hazards under current and future climate conditions for the Rockhampton Regional Council. The project considered tropical cyclone wind, bushfire, storm tide, coastal erosion, and sea-level rise. Outputs include a technical report, hazard maps, and digital spatial data.
Geoscience Australia provides updated navigation data for marine seismic surveys in Australia. The collection includes original navigation files, 2003 SNIP navigation files, and digitised survey track maps, formatted in UKOOA standard P190. Data is available in KML and Shape file formats for use in various geobrowsers.
The Lander Trough in the southern Wiso Basin of Northern Territory contains geological mapping, stratigraphic drilling, and geophysical reassessment data. Beneath superficial material, three rock sequences are distinguished: Late Palaeozoic sandstone, Cambrian or Ordovician sediments and volcanics, and Proterozoic basement. The trough is a crustal downwarp approximately 300 km long and 100 km wide, bounded by a fault system linked to the Alice Springs Orogeny.
Tasmania's Forth River near Devonport was the site of a seismic refraction survey conducted in 1960. The survey aimed to ascertain bedrock depth and type for a proposed dam site, as requested by the Hydro-Electric Commission of Tasmania. The record is provided by Geoscience Australia Data.
High-resolution bathymetry data was used to model landscape change during sea-level rise in the Bass Strait region. The analysis finds shoreline transgression rates exceeding 30 meters per year, indicating 15 kilometers of land would drown within a human lifetime. This dataset, published in Quaternary Science Reviews in 2025, provides a benchmark for understanding land-bridge flooding and its impact on human migrations.
Qilian Shan region seismic data supporting crustal structure analysis. The dataset comprises receiver functions derived from short-period dense seismic arrays, authored by Long Chen and published under CC-BY-4.0 license. It was last updated on May 13, 2026, and is distributed as a 139.9 MB ZIP file.
The Early to Middle Cambrian Stansbury Basin preserves a palaeogeographic zonation from shallow shelf carbonates to extensional rift facies. Sedimentation occurred from about 540 Ma to at least 510 Ma, with a distinctive phase of thick rift sedimentation in the Kanmantoo Trough from 526 Ma. This dataset, provided by the Australian Ocean Data Network, describes the basin's tectonic framework and its potential for various types of mineralisation.
A 7.4 MB Excel dataset containing expression profiles of circular RNAs in bronchoalveolar lavage fluid cells from mice exposed to fine dust PM2.5 particles. The data accompanies a freely accessible journal article and was authored by Kayla Valladares. It was last updated on May 13, 2026.
Colorado's Surface Water Supply Index (SWSI) compares current basin water volumes against historical data for the same month. The dataset provides sub-basin-level calculations including streamflow, forecasts, and reservoir storage components. It is published by data.colorado.gov and was last updated in April 2026.
Forty-two major Mesozoic lithofacies types were recovered from a 1990 dredging program on the northern Exmouth Plateau and Rowley Terrace offshore northwest Australia. The Australian Ocean Data Network hosts this dataset, which provides geological control for seismic interpretations. The rocks document Late Triassic to Early Cretaceous depositional environments, including shelf carbonates, volcanics, and siliciclastics.
14C dating of mollusc shells and sea-grass root fibres reveals a 6000-year history of relative sea-level fall in northeastern Spencer Gulf. The dataset, provided by the Australian Ocean Data Network, includes precise elevation measurements of beach ridges and subtidal sea-grass deposits. It details four distinct events from 6000 years B.P. to the present, with sea level falling from a peak of +3-4 meters to near present levels.
