A 2006/07 marine survey by Geoscience Australia acquired seismic reflection, refraction, and potential field data over the Capel and Faust Basins on the Lord Howe Rise. The report describes velocity data aimed at improving sediment thickness estimation for evaluating petroleum prospectivity in these frontier basins. It reviews seismic reflection data, sonobuoy refraction data, and stacking velocities from processing.
Interpretation data from approximately 6,000 km of 2D seismic surveys acquired over the remote Capel and Faust basins in late 2006 and early 2007. The record was published by Geoscience Australia and is intended to complement the release of digital interpretations in workstation formats. Scientific conclusions from the integrated seismic, potential field, and bathymetry data are published separately.
A 1959 seismic refraction survey determined depths to bedrock at the Callide Creek dam site in Queensland. The survey, conducted for the Queensland Irrigation and Water Supply Commission, includes cross-sections showing rock layers identified by seismic velocity. After correcting a systematic 18% underestimation, depth determinations were accurate to within 10 feet.
Geoscience Australia Data provides a geological assessment of the Lander Trough in the Northern Territory's Wiso Basin. The report describes three rock sequences, including a thick Early Palaeozoic wedge, and analyzes the trough's structure as a 300 km by 100 km crustal downwarp. The data was last updated on 2026-04-30.
Interpretation of seismic refraction data reveals sediment thickness up to 10 km and Moho depths from 19 to 29 km in the Gulf of Papua and northwest Coral Sea. The dataset, from Geoscience Australia, models the crust as continental under the Papuan Peninsula and Eastern Plateau and oceanic under the Moresby Trough. It supports tectonic models for the region's formation under tensional stress.
A 2026 dataset from Geoscience Australia describing submarine volcanoes in the forearc region of the Solomon Islands' New Georgia Group. The report details specific features like Kavachi, Kana Keoki, and the elusive Cook volcano, noting their composition, activity, and depths. It highlights the region's poor bathymetric survey coverage and the need for modern sonar mapping.
Niue Island is a raised coral atoll with an area of 259 km^2 and a freshwater layer that varies from 40-170 m thick. The dataset likely contains results from drilling, gravity, magnetic, and electrical resistivity surveys conducted by Geoscience Australia. It describes the island's unique aquifer structure, where the classical Ghyben-Herzberg freshwater lens does not exist.
Two dry-season surveys of Keppel Bay and Casuarina Creek in the Fitzroy Estuary, conducted by Geoscience Australia. The dataset includes biogeochemical properties of the water column and underlying sediments, aiming to understand sediment, nutrient, and agrochemical pathways in a macrotidal tropical estuary. The report covers climate, hydrology, sampling strategy, water column observations, and sediment properties.
From 10 to 17 April 1997, the Australian Geological Survey Organisation (AGSO) conducted a marine survey using the R.V. Melville to map the seabed east and northeast of Tasmania, including the deep-water Gippsland Basin. The survey employed a SeaBeam 2000 multibeam sonar system, a magnetometer, and a gravity meter to collect data on seabed morphology, roughness, and geophysical properties. Its aims included supporting tectonic and sedimentological studies, aiding the fishing industry, and planning future geological sampling.
Fresh to brackish groundwaters in the range of 250 to 2250 mg/L occur in fractured bedrock aquifers beneath dryland salinity sites at Yass in the Southern Tablelands of New South Wales. The dataset, provided by Geoscience Australia Data, describes the chemical composition of these waters, which originate from recent meteoric sources and are shaped by water-rock interactions, ion exchange, and microbial processes. The data was last updated on 2026-04-30.
Mid-Proterozoic sedimentary rocks from the southern McArthur Basin in Australia's Northern Territory, documented by Geoscience Australia. The sequence is divided into four stratigraphic groups with thicknesses up to 4500 meters and includes formations of quartz sandstone, basic volcanics, stromatolitic dolostones, and evaporitic deposits. The structure is dominated by the Batten Fault Zone, a half-graben containing up to an estimated 12 km of sedimentary rock.
Model output data generated by the THMB 1.2 (Terrestrial Hydrology Model with Biogeochemistry) simulates water flow through groundwater, rivers, lakes, and wetlands. The dataset provides mean monthly simulated water height above flood stage, river discharge, and inundated area for the Amazon and Tocantins River basins from 1939 to 1998. The model operates on a 5-minute latitude-longitude grid with a 1-hour time step.
Approximately 70 sampling stations in Lago Curuai, Brazil, provide concentrations of suspended solids, dissolved carbon, chlorophyll-a, and measurements of turbidity, pH, temperature, and conductivity. Data was collected by the ORNL_CLOUD organization across four distinct phases of the Amazon's hydrological cycle from 2003 to 2004. This dataset captures seasonal dynamics in a major tropical floodplain system.
Soil carbon dioxide, nitrous oxide, and volumetric water content measurements document a controlled drought experiment in the humid Amazon. Data from the Tapajos National Forest site spans December 1999 to June 2002, with samples collected every two to three months. This dataset was produced by the ORNL_CLOUD organization for the LBA-ECO project to study forest response to severe water stress.
March–May 2016 marine geophysical data acquired onboard the JAMSTEC vessel R/V Kairei in collaboration with Geoscience Australia. The dataset includes a 680 km long east-west seismic profile, ~600 km of high-resolution 2D seismic data, and multibeam bathymetry, gravity, and magnetic data. It was presented at the 2016 Seismological Society of Japan Fall Meeting.
Gridded regression coefficients derived from satellite altimeter data for the Antarctic Ice Sheet. The data result from a multiple linear regression analysis of ice surface elevation time series, including parameters for the Southern Annular Mode (SAM) and El Niño/Southern Oscillation (ENSO). Four grids are provided, derived from analyses with different spatial smoothing filters and firn densification model corrections.
Soil samples from 11 sites on the northern Tibetan Plateau contain measurements of physicochemical properties, microbial biomass, enzyme activities, and microbial abundance. The dataset, created by Luyun Chen and last updated on 2026-04-26, includes soil organic carbon, total nitrogen, phosphorus, C:N:P ratios, bacterial and fungal abundance, and extracellular enzyme activities. These data can be used to examine associations between precipitation variation and soil elemental imbalance, microbial stoichiometric stability, and resource-acquisition strategies.
G-LiHT's Canopy Height Model (GLCHMK) data product provides LiDAR-derived maximum canopy height and canopy variability information. The data is collected by NASA's Goddard Space Flight Center using an airborne imaging system over forest communities in the Conterminous United States, Alaska, Puerto Rico, and Mexico, starting in 2011. Processed data is provided as a Google Earth overlay KML file at a nominal 1-meter spatial resolution over locally-defined areas.
