Research from 2026 by Dr. Chris Carson of Geoscience Australia and collaborators analyzes heat-producing elements in Antarctic rocks. The study measures heat production values ranging from 0.02 to 66 µW per cubic meter along a 275 km Prydz Bay coastline transect. This data challenges the assumption of uniform crustal heat flow in East Antarctic ice sheet models.
Water Framework Directive (WFD) Operational Catchments Cycle 2 is a dataset grouping WFD waterbodies at a scale smaller than management catchments. The data is provided by the Government Digital Service under an OGL-UK-3.0 license. It is based on surface water boundaries and excludes underlying groundwater data.
OPP-PRF: Remote Pathways of Ocean Heat Transport toward the Antarctic Ice Sheet is a NASA Earthdata project investigating mechanisms linking offshore ocean circulation to Antarctic ice melt. AMD_USAPDC researchers will use Lagrangian particle experiments in a Southern Ocean state estimate and autonomous float data from West Antarctica. The project aims to quantify pathways of Circumpolar Deep Water from the Antarctic Circumpolar Current to the continental slope.
A joint NSF/GEO-NERC project investigates the direct influence of surface meltwater on Antarctic Ice Sheet flow dynamics. The research includes a field campaign on Flask Glacier and a continent-wide remote sensing survey to test hypotheses about meltwater's impact on ice velocity and discharge. Project activities are scheduled through July 2026.
NASA Earthdata hosts a dataset from a project by AMD_USAPDC to revise models of glacier-ocean interactions. The project uses laboratory experiments to study melt rates influenced by ice roughness, geometry, ocean turbulence, and density stratification. Data includes high-resolution velocity, density, and temperature measurements near the ice-ocean interface, with a last updated date of 2026-04-30.
Geophysical models integrate 26,000 km of gravity and magnetic data with 2D seismic reflection data to interpret crustal architecture in the Houtman Sub-basin. The study was conducted by Geoscience Australia using data from surveys in 2008-2009 and 2014-2015. Its primary aims are to model sediment thickness, basement composition, and magmatic rock distribution.
The Gippsland region of Australia is the focus of this case study on marine seismic survey impacts. Researchers from the Australian Ocean Data Network published an integrated assessment of monitoring methods in 2018. The work analyzes field-based approaches for studying effects on cetaceans, fish, and invertebrates.
800 kilometers east of Brisbane, this collection contains integrated 2D seismic reflection, sonobuoy refraction, and marine potential-field data from deep-water basins. The Australian Ocean Data Network provides this dataset for the remote Capel and Faust Basins, located in 1000-3000 meters of water. It was last updated in April 2026.
Australia's 2019 National Gravity Compilation provides a continent-wide grid of de-trended global isostatic residual anomalies with a 435-meter cell size. It integrates nearly 1.4 million ground stations and 451,000 line kilometers of airborne gravity and gradiometry data collected from the 1940s onward by government, industry, and research bodies. The grid is processed with a tilt filter to highlight geological unit edges.
Nearly 1.8 million gravity observations, including 1.4 million ground stations and over 450,000 line kilometers of airborne surveys, were compiled to create this continental-scale grid. The Australian government's Geoscience Australia processed and quality-checked the data, which integrates measurements from the 1940s to 2019. This 2019 compilation applies a de-trended global isostatic residual (DGIR) tilt filter to highlight geological structure edges.
GBR4_H2p0 is a 4km-resolution hydrodynamic model of the Great Barrier Reef, forced by ocean boundary data from OceanMAPS and atmospheric data from ACCESS-R. The model incorporated tidal constituents from the global CSR tide model and river flow data from 71 Queensland rivers. It ran in near-real-time with daily updates until January 2024, when critical river-flow data was lost due to sensor damage during the monsoon season.
Over 1.8 million gravity observations underpin this 2019 national grid, including nearly 1.4 million ground stations and 451,000 line kilometers of airborne surveys. The Australian Ocean Data Network compiled this first vertical derivative grid from the Australian National Gravity Database and global offshore sources. It represents gravity data collected by government, industry, and research bodies from the 1940s to 2019.
Australia and its continental margins are covered by a gravity anomaly grid derived from approximately 1.8 million ground, airborne, and offshore observations. The grid has a cell size of 0.00417 degrees (approximately 435 meters) and integrates data from government surveys, industry, and research organizations dating from the 1940s to 2019. The Australian Ocean Data Network processed and released this compilation, which includes a first vertical derivative transformation of the complete spherical cap Bouguer anomaly.
Nearly 1.8 million gravity observations, including 1.4 million ground stations and 451,000 line kilometers of airborne surveys, underpin this national compilation. The Australian Ocean Data Network released this processed grid, derived from data collected from the 1940s to 2019, to reveal sub-surface geological structures. It represents the half vertical derivative of de-trended global isostatic residual anomalies across Australia and its continental margins.
Gravity anomaly data measures density variations in subsurface rocks across Australia and its continental margins. The compilation integrates nearly 1.8 million observations, including 1.4 million ground stations and 451,000 line kilometers of airborne gravity and gradiometry surveys collected from the 1940s to 2019. The Australian Ocean Data Network released this processed grid, derived from the 2019 Australian National Gravity Grids B series.
A 2019 compilation integrates approximately 1.8 million gravity observations from the 1940s onward. The grid is derived from ground stations, airborne surveys, and offshore data, processed by Geoscience Australia and partners. It provides a half vertical derivative of Bouguer anomalies at a 0.00417-degree cell resolution.

Gravity tilt anomaly data reveals geological structures beneath the Earth's surface across Australia. The compilation integrates nearly 1.4 million ground and marine gravity stations from a national database updated to September 2019. Geoscience Australia processed the data, applying a de-trended global isostatic residual (DGIR) calculation and a tilt filter to highlight geological edges.
