Geoscience Australia's 2014–15 seismic survey data provides a reassessment of the tectonic evolution and petroleum prospectivity of the northern Houtman Sub-basin offshore Western Australia. Interpretation enabled mapping of the Moho, basement, and major syn-rift sequences, along with creation of a 3D geological model covering the survey area. This study significantly reduced exploration risk in this frontier region.
Several cylinders of carbon dioxide (CO2) and methane (CH4) were used as calibration standards to improve measurement comparability. The Boreal Ecosystem-Atmosphere Study (BOREAS) stored these standards in field laboratories in Saskatchewan and Manitoba from May 1994 until November 1996. The dataset is provided by the National Aeronautics and Space Administration.
A 300 km long and 100 km wide crustal downwarp, the Lander Trough contains up to 800 meters of Cambrian and Ordovician sediments. This report details its structure, rock sequences, and petroleum potential based on recent geological mapping and geophysical data reassessment. The Australian Ocean Data Network published the findings, last updated in April 2026.
The Lander Trough in Australia's Northern Territory is a 300 km long by 100 km wide crustal downwarp. This report details three rock sequences, including Cambrian-Ordovician sediments up to 800 meters thick, and assesses the area's petroleum potential based on comparisons to nearby basins. The Australian Ocean Data Network published this geological study, which was last updated in April 2026.
124 seismic refraction profiles were collected from six reefs in the Capricorn/Bunker group of the Great Barrier Reef. The dataset contains geophysical measurements used to map a subsurface discontinuity at depths of 8-23 meters, equated to the boundary between Holocene and pre-Holocene carbonates. This work was conducted by the Australian Ocean Data Network, with data last updated in April 2026.
124 seismic refraction profiles were collected across six reefs in the Capricorn/Bunker group of the Great Barrier Reef. The data, managed by the Australian Ocean Data Network, identifies a seismic discontinuity at depths of 8-23 meters, correlating to the Holocene/pre-Holocene unconformity. This geophysical evidence was used to assess the influence of pre-Holocene substrate morphology on modern reef growth forms.
BMR Cruise 067 collected geological, geochemical, and heatflow data over the Otway and Sorell Basins off western Tasmania. The 29-day 1987 research cruise occupied 130 sampling stations using dredges, corers, grabs, and a heatflow probe. Scientists from the Australian Ocean Data Network gathered samples to assess petroleum potential and regional geology.
A 1987 research cruise collected geological, geochemical, and heatflow data from 130 sampling stations across the Otway Basin and west Tasmanian margin. Scientists aboard the R.V. Rig Seismic gathered rock samples and sediment cores over a 29-day period to assess petroleum potential. The dataset was contributed by the Australian Ocean Data Network.
Australian Ocean Data Network researchers conducted laboratory experiments to quantify the effects of temperature, salinity, and food availability on the burrowing activity of the polychaete Capitella sp. 1. The study measured burrow depth, area of activity, and used pH and O2 fluorosensors to monitor associated changes in marine sediment chemistry. The dataset was last updated in April 2026.
Experimental data examines the effects of temperature, salinity, and food availability on the burrowing activity of the polychaete Capitella sp. 1 and associated sediment chemistry. The dataset includes measurements from controlled laboratory experiments using pH and O2 fluorosensors. Data was contributed by the Australian Ocean Data Network and last updated in April 2026.
Nauru Island's karst aquifer features a thick brackish water mixing zone where salinity increases gradationally to seawater at about 70 meters below sea level. Groundwater chemistry evolves from HCO3-Ca-Mg type to seawater, with saturation indices for carbonate minerals like dolomite and calcite increasing with salinity. This dataset from the Australian Ocean Data Network, last updated in April 2026, documents these chemical transitions.
Hydrochemical data describes the evolution of freshwater to seawater across a brackish mixing zone in Nauru Island's karstified dolomitic limestone aquifer. The dataset, provided by the Australian Ocean Data Network, was last updated in April 2026. It details saturation indices for carbonate minerals like dolomite, calcite, and aragonite across a salinity gradient.
Miocene-Pliocene and Eocene-Oligocene volcanic features were identified on the seafloor of the northern Lord Howe Rise. The dataset includes analysis of seismic profiles and swath bathymetry from a Geoscience Australia survey. Findings were presented at the Australian Earth Sciences Convention in July 2010.
A Geoscience Australia survey identified volcanic cones, flows, and sills on the Lord Howe Rise seafloor. The data includes at least two distinct volcanic ages: Miocene-Pliocene (approximately 4-7 Ma) cones and Eocene-Oligocene features. Findings were presented at the Australian Earth Sciences Convention in July 2010.
Palynological analyses from four fully cored boreholes in the central west Murray Basin provide a biostratigraphic framework for groundwater-related geology. The study, augmented by analysis from other boreholes, was conducted by the Australian Ocean Data Network. It focuses on sediments from the Early Cretaceous to the Middle Miocene, including the Geera Clay aquitard and Renmark Group aquifers.
Palynological data from four fully cored boreholes in the central west Murray Basin provides a biostratigraphic framework for groundwater studies. The analysis, augmented by cores from other boreholes, identifies pollen and dinoflagellate zones from the Eocene to Miocene epochs. This work was contributed by the Australian Ocean Data Network.
Volume 15, issue 3 of the AGSO Journal contains nine peer-reviewed scientific articles covering topics from cleavage classification to paleontological records. The journal issue was published by the Australian Ocean Data Network and was last updated in April 2026. It serves as a collection of primary research in the earth sciences.
Volume 15, issue 3 of the AGSO Journal compiles nine peer-reviewed research articles on Australian earth sciences. The collection was published by the Australian Geological Survey Organisation, now Geoscience Australia, and is hosted by the Australian Ocean Data Network. The platform's metadata indicates a last update in April 2026.
Evidence from earthquake focal mechanisms and in-situ stress measurements indicates substantial horizontal compression across the Australian continent. Data includes reliable focal mechanism determinations from eight earthquakes since 1967 and in-situ measurements from mines, tunnels, and quarry floors across multiple states. The dataset is provided by the Australian Ocean Data Network and was last updated in April 2026.
Solomon Islands submarine volcanoes in the New Georgia Group forearc are documented, including the frequently active Kavachi volcano and the elusive Cook volcano. The dataset compiles reported volcanic activity, bathymetric survey findings, and geological composition from sources like the Australian Ocean Data Network. Information was last updated in April 2026.
